*********************

"It's hardly surprising that you've decided to reduce your waist," said Megan as she carefully measured Gloria's waist. "After all, with Mandy down to 15 inches and having her own range of corsetry and accessories, it's certainly time you joined the team."

"Yes, well, I just know how Stan looks at her; he used to look at me like that, with the hungry look as his cock tents his pants, but now it's all for her. So, maybe if I shrink-wrap myself he'll once again look at me like that. Besides, it's a challenge. I actually don't really need Stan, I prefer to make love with Mandy and I know she likes Stan's cock in her, but he's my husband so I guess I should do all I can to please him."

"Oh, I'm sure that just seeing you in a tight corset will please him," replied Megan, standing up with her measuring completed. "Now, how about we try a belt on you and see what we can get you down to today. Then we'll have a good idea of how much we should aim for with your first corset."

Gloria held the bar as Megan wrapped the belt around her midriff, sliding it through the loop and pulling it tight.

"How does that feel?"

"It's tight, but certainly not uncomfortably so. Can it go tighter?"

Megan pulled it another inch tighter then fitted the hooks onto the loops.

"I'll tighten it up here. Let me know if it feels unbearably tight."

Megan operated the over-center clasps and pulled the belt in another inch, this time fastened in place with the clasps.

"How's that feel now?"

"Really tight. I can feel my internal organs protesting, but it's bearable and for a good cause, so that's fine, thanks."

Gloria released her grip on the bar and cautiously brought her hands to her sides, experimentally moving to feel how the pressure felt around her waist. She walked a few steps before facing Megan with a grin on her face.

"It feels great. I never realized it would feel so sexy. No wonder Mandy likes it."

"Yeah, well, I guess that's why people wear corsets. The feeling is a combination the physical stimulation by compression of the internal sex organs, which we women have, as well as feelings of confidence that a small waist brings, plus the satisfaction of achievement at being able to improve upon nature. Add to that the extra attention sex-starved males pay us, and you have the perfect storm, or at least the perfect seduction. You'll find that men will most definitely treat you differently when you have that hourglass look."

"Oh, how about women? I think I prefer women to men. Certainly, I'm very grateful that Stan fills Mandy with most of his sperm, rather than always wanting to fuck me, and I really enjoy cleaning up her sloppy pussy afterwards."

"Well, then, I guess you most certainly have the best of both worlds. Would you like to feel how it feels to cum while wearing the belt?"

Gloria needed no second invitation. She turned towards Megan, wrapped her arms around her and the two women kissed, their tongues duelling, as Gloria unfastened the few buttons of Megan's top and skirt, removing her top so their naked breasts pressed against each other's, then pushed her skirt to the floor and cupped her flowing pussy beneath her bikini panties. After a few minutes they parted, their breathing short and rapid as they walked to the couch. Megan slipped her panties off as she lay on the couch and Gloria straddled her, her mouth at Megan's pussy, her pussy at Megan's mouth, in a sensuous 69.

Each woman explored, licked, caressed and penetrated the other with tongues, teeth and fingers. Gloria felt the arousal caused by the tight waist belt, felt how the constriction prevented her deep breathing, knew for the first time what Mandy had been through to achieve her 15-inch waist, and also felt her orgasm approaching as Megan expertly nibbled on her clit. She responded in kind and was rewarded by Megan's body writhing under her ministrations. She pushed a third finger into Megan's flowing vagina as Megan bit down harder on her clit, the combined added stimulation pushing them both over the top.

Both women were lost in their mutual orgasms, writhing against each other, neither hearing the door opening or the footsteps on the carpet. As they both relaxed in post-orgasmic bliss, Gloria was startled by a hard slap to her ass. She quickly turned her head and saw Stan standing beside her, a broad grin on his face.

"All part of the fitting process, no doubt," he said as he stepped back, giving the women space to disentangle themselves.

"Yes, darling, an essential part as well," smiled Gloria.

"An absolutely essential part," added Megan, reaching out to unzip Stan's fly and release his erect cock, "And it seems like your measuring stick's ready for some use as well."

"Mmmm, honey, so soon after Mandy emptied him this morning. I'm sure Megan has a remedy for that problem. She's so good at fitting things into places, aren't you, sweetheart."

Gloria and Megan vacated the couch, quickly stripped Stan and indicated that he should lie on his back, which he did, his cock waving in the air. Megan knelt beside the couch and took him deep into her mouth, deep-throating him for a few strokes before straddling him, sliding his cock into her wet vagina, then sitting down hard. Once she was seated, Gloria straddled her husband's face and positioned herself so that he could eat her pussy, which he began doing, sliding his rolled-up tongue into her gaping love tunnel, then licking and nibbling her clit. Meantime Megan had wasted no time in sliding back and forth on his cock, forcing it into her hungry hole as she and Gloria kissed and massaged each other's breasts, pinching and twisting their nipples to create jolts of sensuous pleasure through each other's body.

Despite having cum very recently, both women quickly approached their orgasms due to the multiple sources of sensation, while Stan also rapidly lost any control of the situation as his release approached while he struggled to breathe around his wife's pussy. He came first, his groaning muted by Gloria's pussy as he thrust upwards into Megan's cunt as hard as he could before squirting her full of his boiling cum. The feeling of being filled pushed Megan to her orgasm, causing her to give Gloria's nipples an extra strong twist which pushed her into full orgasm as well. She sat down hard on Stan's face, reducing his source of air still further as she writhed against Megan. Stan struggled to breathe, was unable to obtain enough air and fainted from lack of oxygen.

It was only a matter of seconds before both Megan and Gloria realized Stan's predicament. Gloria lifted herself off her husband's face and felt a wave of relief as he took a deep breath of air, then several more, then his eyes opened.

"Whew, that was intense," he said, once he could speak.

"Sorry, honey, I forgot you needed to breathe."

Gloria knelt beside the couch and kissed Stan briefly, allowing him to breathe. Megan lay backwards and slid off Stan's now deflating cock.

"Gloria, want some early lunch, darling?"

Gloria certainly wasn't going to turn down Stan's second-hand offerings from Megan's pussy. Quickly she began licking and sucking at her love hole, pulling her labia apart to suck out her husband's cum while also mouthing her clit and whole pussy area. The process took several minutes and only ended when Megan threw her head back and let out a scream as she came once again.

While Megan lay on the couch recovering, Stan held Gloria at arms' length looking at her tightly cinched waist.

"Like it, honey?"

"I do like it," he replied, observing afresh her curvaceous body and the way the smaller waist seemed to emphasize her breasts, "Are you going the whole way with corsets and everything?"

"Absolutely, if you want me to. I'd like to get down to 15-inches, like Mandy."

"Why are you doing this?"

"Well, the main reason is the challenge," replied Gloria, not wanting to admit that she also wanted the same attention from her husband that he had been paying to Mandy.

"Ok, yes, I like it and yes, please go ahead. It'll be great to have two corseted women in bed each night. Can I try to tighten your belt one more notch, darling?"

"Sure, honey, if you can."

As Megan dressed herself, Stan and Gloria kissed, then Gloria held the bar and concentrated on pulling her belly in as far as possible as Stan first tightened one, then the other, of the clasps. Once he was done, Gloria dropped her arms and moved her body, feeling the beginnings of the feeling that Mandy had described where the lower half of the body seemed to be out of contact with the upper part. She took a few steps, nearly fell but recovered, then stepped out more confidently. Even despite having cum so recently, the sight of his wife so tightly constricted had Stan becoming hard once again. However, he had work to do, so pulled on his clothing, kissed Gloria and walked out of the room, having completely forgotten why he had entered in the first place.

Gloria dressed, noticing how baggy her dress felt on her with her cinched waist, then carefully made her way downstairs and home. She decided to keep the belt on for the rest of the day before collecting her first corset, which Megan had said would be ready tomorrow.

When I returned home that evening, I admired Gloria's new shape as she stripped down to only her belt in our bedroom.

"What do you think of tight lacing?" I asked Gloria.

"Well, so far so good. Yes, I enjoy it, but I now know what you meant by the feelings you described."

"Great. Welcome to the club. Have you cum in it yet?"

"Yes, that was wonderful. I came with Megan while Stan fucked her. Quite a session, especially as Megan and I had both cum just before Stan arrived."

Gloria described the scene in Megan's office earlier in the day. During the description I sat with Gloria on the bed, crossing and uncrossing my legs as I felt my pussy flooding with arousal. At last she'd finished.

"Well, that's made me really horny. It's been ages since I came, a whole ten hours or so, which is almost a lifetime for a nympho like me," I chuckled, reaching towards Gloria.

She came towards me, and we embraced. She slowly stripped me down to my corset and crotch strap and we kissed sexily.

"I'm going to fuck you hard with the big dildo," I whispered into her ear, "And you're gonna love it!"

I fetched the dildo from the drawer and removed my tight crotch strap, then we made love together, each teasing, caressing, squeezing the other's breasts and nipples as well as opening each other's love tunnels until we were both past ready. I pushed one end of the dildo into Gloria's hole as far as it would go, then pushed the other end into me, feeling it work its way inside my tight sheath until we were able to lie together, our pussies touching, our legs scissoring each other's upper body as the huge dildo completely filled us both. Our hands reached for each other's pussy, caressing clits and asses as we moved our hips together, keeping the huge dildo completely inside our stretched vaginas as our arousal grew and we approached our climaxes. I needed more movement, so I rolled forwards until I felt the dildo withdraw slightly and bend in the middle. I tipped Gloria onto her back and we rearranged our legs so I was straddling her thighs, sitting on the dildo. I then started moving back and forth as well as up and down, causing the dildo to fuck our vaginas and our clits to press together while we could use our hands on each other's breasts.

In this way we rapidly pushed each other to new heights of arousal and after only a few minutes I came hard, leaning forward onto Gloria as waves of sensation poured through me. Feeling me cum on her must have been all that was needed to push Gloria over the top and I felt her hips thrusting up against mine as she moaned in ecstasy and writhed beneath me.

After we recovered we stayed like that, our bodies resting together, joined by the dildo, as we kissed and caressed lovingly. After a long time we parted, each cleaning up the love juices of the other with our tongues, then remained clad as we were for the short time until Stan arrived home. What better way to greet your man than naked, except for a tight corset or belt, and smelling strongly of sex?

Stan greeted us both with a huge smile, kisses and a cock that tented his trousers. We fixed drinks for us all, stripped him down to his undershorts, then told him about our early evening lovemaking, noticing the wet patch growing at the top of his tent pole. We then left him and went to the kitchen to make dinner while he took in the news on tv.

"Is it fair, do you think, for us to be constricted while Stan's completely free?" asked Gloria.

"Hmmm, I don't know. What's on your mind?"

"Well, I thought we could maybe tie up his cock and balls or something. If it's good enough for us to wear corsets and a crotch strap, maybe he could have a belt and crotch strap as well."

"Yes, a good idea. Are you getting a crotch strap with your corset?"

"Yes, absolutely. It'll be like yours, adjustable. I think we should see Megan and ask her to make one for Stan. Good idea?"

"Absolutely. Besides, it was pretty disgusting watching his cock ooze inside his shorts while we told him about our lovemaking, wasn't it?"

"Yes," agreed Gloria, "I'll have a word to Megan tomorrow when I collect my corset."

"I wonder if there's any way we could lock it on him," I mused.

We ate dinner, chatting amiably about non-sexual matters, undressed as we had been before dinner. We made no mention of our intentions for a crotch strap to Stan, he'd find out in due course. After dinner, when the dishes were stacked in the washer, Gloria and I walked Stan arm in arm to the bedroom.

"Right, stud, time to show us what you've got," I told him.

We stripped him and lay him on the bed. He lay quietly, his cock still at attention as it had been all evening, and Gloria produced some rope, with which she tied his wrists to the headboard. Stan looked a little concerned at this but we reassured him that it was fine, but it was our turn to be in charge. He seemed to accept this; what man wouldn't with two almost naked females wanting to tie him up before ravishing him? Then we tied his ankles to the corners of the bed so that he was now completely helpless.

"What now?" Gloria asked me in a whisper.

"I have an idea. Remember you had sore muscles a while ago and used some Deep Heat? Do you still have some?"

"Yes, hang on a sec."

Gloria left and a few minutes later returned with a small pot of Deep Heat in her hand.

"What now?"

"Well, I reckon his cock isn't hard enough yet. Let's try to harden it up, shall we?"

Gloria grinned. "Sounds like a plan."

We scooped generous portions of the cream from the jar and while Gloria began rubbing it on his cock, I began covering and rubbing it into his ball sac. To begin with Stan seemed to enjoy it, then the metholatum began working and he began protesting. Of course, by then it was no use protesting at all; nothing we could have done would have reduced the icy heat he was feeling until it had worked its course. All we did was simply continue rubbing it in as he began thrashing his hips around, trying to get away from our tender stimulation. His cock hardened more, his balls retracted, but still we gently applied the cream while he begged for mercy.

"Oh, poor darling," said Gloria in her most wifely tone as she added yet more cream to the head of his cock, "Do you like that, sweetheart? We'll have to put some more on then."

His protests fell on deaf ears. It appeared that as well as causing heat in his tender parts, it also caused numbness, which is what it was designed to do, just not in this particular muscle. After quite a long time we decided to take pity on him, and instead of rubbing more on we masturbated him instead, trying to bring him to orgasm, but without any success.

"He obviously needs to cum, otherwise he won't sleep well," said Gloria after 20 minutes of masturbation had no effect, "Why don't you fuck him?"

"Why don't you? He's your husband, after all."

"I know you like being fucked far more than me. I prefer women and oral, not cocks. And I know you need to cum after all this, otherwise you'll be grumpy and won't be able to sleep."

She was right. I needed to cum, at least once, and after masturbating Stan for a while I was horny as hell, wishing his cock was inside me.

"Ok, I'll fuck him and he can eat you out, deal?"

"Deal."

While Gloria straddled his face, sighing as she felt him begin to suck and lick her pussy, I straddled him behind her, easing his huge cock into my flowing vagina as she leant back against me, her back massaging my breasts. I reached around her and began massaging her breasts, pulling her nipples out, rubbing them as I moved my hips back and forth, feeling Stan's hard cock reaching all the best places inside me. However, it felt different from usual, there were different sensations inside, more stimulation and more heat. It felt nice at first, warming, sensual, but then Gloria pushed my hands off her breasts.

"Ouch, that's stinging," she cried.

I also felt the sensations in my vagina turn to a stinging sensation and suddenly realized the cause. We both had Deep Heat on our hands and, of course, Stan had Deep Heat on his cock, which was inside me. The heat in my pussy strengthened, and my clit began to feel the sensations as well. However, the sensations caused my horniness to increase and instead of lifting off Stan's cock, I began humping it harder, determined to satisfy myself before finishing.

Gloria was rocking her hips back and forth on Stan's mouth even as she tried unsuccessfully to wipe away the stinging in her breasts. Stan must have done something because she suddenly leant forward, pushing her clit into his mouth as she began gasping as she entered the end phase of her arousal. A few more seconds and she was there, humping against Stan's mouth, moaning as her trembling body experienced a strong orgasm.

The sensations of his wife orgasming on his mouth must have spurred Stan on to greater efforts as he fucked into me hard, lifting my knees off the bed as his huge cock pressed into the very end of my heated cunt. Then he held still, fully implanted inside me, and I felt his spurts of sperm flooding the end of my love tunnel. Despite the numbness and heat in my vagina, or maybe because of it, I came hard, the muscles in my vaginal walls clenching and releasing, sucking every last drop of cum from Stan as his cock pulsed inside me rhythmically.

We slowly collapsed onto Stan's bound body. Gloria reached forwards and unfastened his wrists, allowing him to hold us both. I felt his juices slipping down my tunnel past his softening cock, soothing the heat in my inflamed membranes, feeling Gloria's body beneath me relax as her breathing slowed. We rested like that for a long time, joined in post-orgasmic bliss as Stan's cock shrank and slowly slipped from my grasp.

When the time seemed right, I sat up and dismounted, allowing Gloria to do the same and untie Stan's ankles, until he also was able to sit up. We kissed, then I removed my corset, Gloria her belt and we all showered together, trying our best to remove all traces of Deep Heat from our bodies. Once that was done, we dried each other and climbed back into bed.
"Did you like your surprise, darling?" asked Gloria.

"Oh yes, and I seem to think it was a surprise for you also."

"I had certainly not thought that through," I commented, "Next time when we use Deep Heat I must let Gloria fuck you, not me."

"C'mon, you enjoyed it, didn't you?" asked Gloria.

"Yes," I admitted, "It was a wonderful experience and yes, I'm sure we'll do it again. I guess it was the surprise factor that caught me unawares."

"Me too," agreed Gloria.

"Me three," added Stan, as we settled into bed, one of his arms around each of us as we lay contentedly alongside him and fell asleep.

The following afternoon Gloria and I returned to collect her first corset. We went to the fitting room and Gloria stripped, then Megan fitted the red satin corset around her waist and began tightening it. It had been a snug fit when loose, as it was designed to be, and as the laces tightened Gloria felt the first effects of the unfamiliar constriction.

"Mmm, that feels good," she said with a smile, watching herself in the mirror as her waist began to slim. "I can only imagine what it must feel like when it's really tight."

"Well, soon you won't need to imagine because it will be really tight," replied Megan, pulling harder on the laces, "We obviously won't pull it up to its tightest today. Your body will need time to adjust, as you know from watching Mandy's body change."

Eventually Megan was satisfied with her efforts and stepped back to gain a better overview of the new garment. Gloria stroked her sides with her hands, feeling her compressed body encased in its sleeve of red satin. She tried walking, noticing the slight loss of control as she had to grip the back of a chair to steady herself.

"It feels like my insides are moving around looking for somewhere to spread," she said.

We laughed. "Yes, that's probably what's happening," I agreed, "Mine certainly have been looking for new places to go. Megan, I wonder if you'd mind looking at something for me please before we leave today."

"Sure, in a few minutes after we've finished with Gloria."

She made a final adjustment then she embraced Gloria, feeling her tight body against her own.

"I can't wait until we make love together," she whispered in Gloria's ear, "Sorry, I should have allowed more time between appointments today."

"That's fine, it'll wait for a while," replied Gloria, kissing Megan sexily.

While Gloria dressed, Megan asked me what she needed to look at.

"Well, I've noticed that recently when Stan has been fucking me he hasn't need able to enter me as deeply as before. It's as though my cunt's shortened or something. Can you have a look please."

I sat on the chair and wriggled my hips to the edge of the seat so I could spread my legs. Megan unfastened my crotch strap and spread my lips apart, then looked closely.

"This happens with tight lacing sometimes," she said, "It seems like your uterus has prolapsed, meaning that the pressure in your abdomen is pushing your womb down your vagina. Of course, this means that your cervix enters the top of your vagina and as the internal pressure increases, it moves further down, effectively shortening your cunt, as you've noticed."

"So, what do I do about it?" I asked.

"Well, firstly you stop tight lacing allow your abdomen to expand to accommodate your womb better, then you can exercise more to strengthen your pelvic floor muscles. If that doesn't work, you may need surgery to either reposition your womb from where it's moved to or have a complete hysterectomy."

I thought for a few seconds, then decided that none of these were good options. I did not want to stop tight lacing, did not want to give up the joy of being severely constricted. There had to be another option.

"What if I want to continue tight lacing?" I asked.

"Then, my dear, you will have to put up with the consequences." She grinned up at me. "There is another possibility which I've thought about if this was to happen to me, but it probably isn't recommended."

"What's that?" I asked, grasping at any possibility in the maelstrom of emotions I was feeling.

"You could use what you've got. I've seen online where a woman with a prolapse could take objects in her womb by stretching her cervix. She could take quite long and reasonably thick sounds through her cervix and into her uterus."

"As thick as Stan's cock?" I asked.

Megan chuckled. "Probably not, at least it wasn't shown, but that doesn't mean you couldn't work up to something like that."

My mind went into overdrive thinking about Stan fucking me in my womb, giving me direct sperm injections. "So, what do I need to do for that?" I asked.

"Why don't I come around tonight and we can explore," suggested Megan.

"It's a date."

"One more thing," said Gloria, now fully dressed, "We were discussing crotch straps and we've decided that Stan needs one as well as us. Good for the goose, and all that. Do you have any suggestions?"

Megan grinned. "Absolutely," she replied, "I'll bring a few around tonight and we can see how you like them."

We shared kisses and cuddles with Megan, then we left as her next client approached her door.

Once we arrived home, we both quickly stripped off our clothes, leaving our corsets on.

"I want to see if you can tighten me up any more," said Gloria, "It feels looser that it was so must have stretched."

"More likely you've shrunk or changed shape a bit," I commented as I untied the laces and began pulling the edges closer together as Gloria held a door frame for support. After a while I had tightened it as much as I could and tied off the laces. Gloria tried walking in it and found she was quite wobbly, which she took as a sign of progress.

"Now I want to see your cervix," she told me.

We went to the bedroom and I lay on my back on the bed, legs wide apart. Gloria removed my tight crotch strap and used her fingers and thumbs to spread my labia, then gently pushed her fingers inside my opening. Once they were inside, I could feel her pushing them in further then I felt her touch my cervix, which seemed to be only a half finger depth up my vagina, far lower than it was a few days earlier when I'd first noticed it.

"It's right there, almost popping out to meet me," she exclaimed. "How sexy is that!"

"I guess it's real sexy for you because it's not happening to you - yet. But it's a bit of a problem for me. Stan won't want just the head of his cock inside me, and what happens next? Does my whole womb come rushing out to meet you?"

Gloria considered this for a few minutes, all the while slowly stroking her fingers inside me. My mind released the concerns for my future as it focussed on the pleasures of the present and my hips began their dance of arousal automatically. Then Gloria changed her movements, inserting the fingers of both hands into my loosening entrance, pushing inside with two fingers of each hand until they bottomed out as they reached my cervix. She grinned up at me as I craned my head forwards to see what was happening.

The Gloria began stretching the sides of my entrance apart, pulling quite hard as she looked inside intently.

"I can see it," she cried, "I can see your cervix. It's all shiny and wet with a sort of closed hole in the middle, and it's only a few inches from the entrance. Push down, like you were straining to shit, and see if it moves further down."

She was obviously so lost in the moment that she seemed to have forgotten that I may not really want to force my womb out my cunt. However, I thought it would be an interesting experiment so I gritted my teeth and pushed, imagining that I was giving birth to a baby. I seemed to feel a spreading apart of my vaginal walls, which I thought might be my uterus moving downwards.

"Yes, it's moving down," came a joy-filled cry from Gloria. "I wonder how far you can push it down."

I relaxed. I didn't really want my uterus hanging out of me. But I had to admit, it was an interesting sensation.

"It's stopped coming to meet me, but hasn't retracted much when you relaxed," commented Gloria.

How far did I want to take this, I wondered? I remembered Megan's comment about using a sound to slide through my cervix.

"Do you want to try penetrating my cervix?" I asked Gloria.

"Ooohhh, yes, darling, that would be so fun. Can I?"

I nodded and Gloria opened our toy cupboard and selected a stainless-steel sound which, until now, had only been used in Stan's cock but would now penetrate my cervix. She wiped it with sterilizing solution, then knelt between my legs once again.

"I'll just coat the sound with some of your natural lube, which is oozing everywhere," Gloria told me as she rolled the sound around my inner labia. "Ok, it's sure slippery enough so here goes."

I felt the cold steel probing gently at the opening to my cervix, then, with a slight twinge of pain, it slipped inside.

"It's inside and I'm moving it back and forth," said a grinning Gloria.

"You're enjoying this, aren't you?"

"Oh yes, it's so hot, so sexy," she replied as she continued to move the sound inside me. I could feel a tugging sensation so asked what she was doing.

"I'm moving it sideways, trying to open the hole a little larger," she explained.

"Wouldn't it be easier to use a larger sound?"

"Probably, is that Ok with you?

"There's no pain, so yes, that's fine."

Over the course of the next hour we went from Gloria's tentative initial insertion to the largest sound in our collection, far larger that we had used on Stan, and I took them all. Once the entrance had been opened and had relaxed sufficiently, Gloria tried pushing the largest sound inside to see how much depth she could achieve. I could barely feel any movement so relied on her to tell me how far in it was as she slowly fed more and more inside.

"Ow," I yelled as I felt pain much further inside me that I would have expected.

"That must be the top," replied Gloria, retracting the sound slightly. "How's it feel?"

"It's fine except for when it hit the end. How far inside me is it?"

I felt Gloria's finger move between my lips then she removed the sound, her finger indicating the depth. It looked to be about three inches.

"All that was in my womb?" I asked.

"Yes, and there was another couple of inches inside your cunt as well. The sound was almost buried inside you."

"Wow, that's amazing. Do you want to try a finger now?"

"Ooohh yes, if that's Ok with you."

"Sure, just sterilize it first."

I watched as she sterilized her middle finger, the thickest and longest, then she let it air dry before running it around inside my pussy to collect my copious lube. Then she inserted it first into my vagina, where I could barely feel it, then I felt her spreading the cervical opening, gently easing the end of her finger inside. I watched her hand as it slowly approached my labia, the finger easing inside me, pain-free, with barely any feeling. The sexual excitement of this operation was most certainly not from a recipient's perspective, but was largely from observation of what was happening; all in the mind, your most powerful sexual organ.

"That's as deep as I can go," she said as I felt her clenched fingers pressing against my labia. I felt a surge of disappointment, then had an idea.

"Can your clenched fist fit inside my cunt opening?" I asked.

"Probably, do you want me to try?"

"Oh yes," I said, feeling the increasingly desperate need for some real sexual stimulation.

Gloria used her other hand to ease my pussy lips around her clenched hand, taking care to move it as little as possible. I felt my opening stretching as it fitted snugly around Gloria's clenched fist. I had been fisted in the past by both Gloria and Stan, so I knew her fist would fit inside and also knew that each time I had been fisted, I had cum hard. I felt the stretch spread to my clit and knew it would be engorged, sensitive and just crying out for attention.

"That's starting to feel really good," I said, "Can you stimulate my clit too, honey?"

"Sure, just be a little patient; wait till I'm fully inside."

A few minutes later I felt the twinge of pain once again.

"Ow, that's the end."

"Yes, I felt it too," she replied, pulling back slightly, "How's it feel?"

"Yeah, Ok, not as sexy as I'd have expected, and I really need to cum."

"I guess there aren't many, if any, nerve endings inside your uterus. If there was, then carrying a baby could be a nightmare. Now, the sexy bit, let's see what I can do for you."

Gloria began moving her hand back and forth very slightly, careful not to allow the rim of my tight entrance to slide off her fist. She also bent her head forward and took my engorged clit between her lips, using her tongue and lips, then her teeth to stimulate my sensitive organ. I relaxed, my head dropping back against the cushion as waves of erotic sensations poured through me. I began unconsciously humping my hips up and down, feeling Gloria's arm moving with me. Within a few seconds it seemed I was there.

"AAAARRRRGGGGHHHH!!" I screamed as I dropped into orgasmic ecstasy, waves of bliss pouring through my shuddering body.

Slowly I returned to reality, becoming aware of my surroundings, of Gloria watching me with wide eyes and a smile, and of her hand and finger fully inside the deepest core of my being.

"Mmmm, thank you, darling, that was wonderful," I murmured.

"Pleased you enjoyed it," she replied as she began slowly extricating her hand from my still clasping cunt. "We'll have to do it again sometime."

"Absolutely, and I want Stan to fuck me through my cervix too."

We cleaned up and spent the remainder of the afternoon in our corsets and very tight crotch straps only, waiting for Stan to arrive home. We discussed possibilities including putting a ball or other object into my opening before tightening the crotch strap, and pushing a water balloon inside my womb, then inflating it with water to expand my womb.

"After all, it must be able to expand, it's designed to take a baby," said Gloria.

"Yes, but that expansion takes nine months and is helped by hormones, we'd be doing it in a few minutes without hormones. Still, could be fun."

Stan was late and supper was ready when he arrived. He admired Gloria in her new corset then, as we ate supper, we told him what we'd learned today, the fun we'd had and the fun we had planned for him tonight. His cock was hard and drooling before we were even part way through.

"See, he certainly could do with a crotch strap to keep his appendage under control," said Gloria, "Saturday morning we have a fitting planned for you with Megan."

I noticed that his already hard cock seemed to become even harder at the mention of Megan.

We left the dirty dishes and headed to the bedroom where Stan wasted no time in making love with Gloria, still horny from the unreleased sexual tension after our earlier session. I watched as the lovers consummated their relationship, Stan commenting that Gloria felt much tighter than usual in her corset, which was very arousing. Gloria, for her part, managed to cum twice without allowing Stan to cum, meaning that when he turned to me he was still hard and ready.

"So, what do we do with you?" he asked.

Gloria roused herself after her second intense orgasm and knelt on the bed beside my spread legs.

"First off, you don't need to arouse Mandy because she's already aroused, so just spread her opening and have a look inside."

Stan did this and sure enough he could see my cervix part way down my vagina.

"It's right here," he exclaimed, "No wonder you've felt so shallow these past few times."

"Yeah, sorry sweetheart, I only found out today."

"But watch this," said Gloria, "Mandy, force down hard."

As Stan watched, I forced down, feeling my womb pushing its way further into my vagina.

"Oh wow. It looks like you're going to give birth to it. The cervix isn't nearly as small as I'd imagined it should be."

"That's probably because we stretched it this afternoon," grinned Gloria.

"So, you think I can put my cock inside your womb, through your cervix?" asked Stan.

"Well, I had my finger in this afternoon," said Gloria, holding up her finger.

"Well, I hope my cock's a bit thicker than that."

"It's designed to stretch; after all, a baby's head comes through it," I mentioned, "So, just do some stretching and we'll see what happens. Your cock's hard enough to cut wood at present, so I'm sure it can open me up without too much trouble."

Gloria spent the next little while repeating the process she'd gone though earlier to open me up, then when my cervix was soft and relaxed on her finger, and Stan's cock was drooling from having watched the whole operation, he stood between my widespread legs and pulled my ass to the edge of the bed.

"Time to go where no man has ventured before," he said dramatically and he bent down and looked at my gaping entrance.

He slipped his cock inside my entrance and pressed forward the short distance until he felt the head touch my uterus alongside my cervix. He then tried moving back and forward in the hope that the head would find the cervix, but to no avail. He moved up and down and sideways, with my hands on his hips guiding him as much as I could by feel, until finally he slipped forward a little more as his head lodged in the opening.

"I think that's it," he said with a smile, "Ready?"

"Yes, fill my womb with your cock, honey."

He pushed forward gently and I felt myself opening wider around his head. It was an interesting feeling, not really painful, not really arousing. He kept up a steady pressure and slowly he moved forward. He was filling my womb with his cock! The knowing that this was happening was far more arousing than the actual feeling of it happening. Stan was obviously far more aroused that I was and he pushed harder, the pressure increasing inside me until finally he was fully in me, his cock deep inside my womb. He grinned at me.

"Still Ok?"

"Yes, honey, it feels strange, but it's fine."

He began pulling out then pushing back in, each thrust and withdrawal becoming easier as my cervix obviously relaxed and expanded. I saw Gloria grinning at me as she stroked her prominent clit, obviously turned on by the scene in front of her. The slow fucking that Stan was doing must have been very arousing for him because I felt him speeding up, his thrusts becoming harder and faster. Then he could hold off the inevitable no longer and with a final deep thrust that pressed his pubic bone against my clit, he spurted his cum deep into me, directly into my womb. I thought it was fortunate that I had a contraceptive implant because otherwise I would have been almost certain to become pregnant.

After a short time, Stan relaxed and I felt his cock softening inside me before he withdrew it completely. He bent to kiss me and I pulled him onto me and we embraced.

"That was so hot," enthused Gloria, "I came too just from watching and stroking."

"Yeah, well it felt good for me too, but not enough for me to cum, so I'm horny as hell."

"Oh, darling, let me eat you out and suck out all Stan's hot cum."

I released Stan and Gloria knelt between my legs as she slid her tongue into my gaping hole then began licking, sucking and stimulating me as only another woman can do for me. I had three orgasms in close succession before she withdrew from me, the smile on her face covered in cum.

After Stan had left the following morning, Gloria and I sat at the breakfast table discussing the situation. We were both in our corsets and crotch straps, with just a sheer gown to keep the morning chill off our skin.

"I think we need to do some cervix training for you," said Gloria at length. "The reason you didn't cum this morning when Stan fucked you was that it took you too long to become dilated, so you missed out on the clit stim. What if you were kept dilated all the time?"
"That'd be cool, but what did you have in mind?"

"Well, there are two things we need to consider. Firstly, you don't want your womb to hang out of your cunt; it's not cool to have your womb between your knees." We both chuckled at the mental image this caused. "And it's also a good idea if your cervix is open and ready rather than having to be dilated each time you want a fuck. So, if we had a plastic device made that would fit into your vaginal opening and push your womb upwards, at the same time having a finger about an inch in diameter that would fit through your cervix, we could solve both problems with the one device, and it could also be held in place with your crotch strap."

I visualized how this would be and imagined how it would feel. Then I came up with an enhancement.

"Great idea, and it could have a tongue that fitted over my clit and it could also have a vibrator inside so I could be stimulated with it in place."

"Yeah, great idea, and it could be a remotely operated vibrator so I could carry the remote and stimulate you at will when we went out."

"Eeeew, you have a nasty mind, but I love the idea. Maybe we have one each."

"That sounds like fun," agreed Gloria, "I guess that I'll need one if my body responds to my tight-laced corset like your has, so why wait?"

We cleaned up the kitchen then did some research for companies that could make moulded plastic objects, finding one not too far away. We dressed in our normal manner, sexily and provocatively, and arrived at the company late morning, to be greeted by the receptionist.

"Good morning, welcome to The Plastic Moulding Company. I'm Melissa; how can I help you young ladies?" she asked.

I was very relieved that the first point of contact was female, it seemed to be easier to explain a situation to someone who was also the owner of the apparatus in question. As we described our requirements, Melissa's eyes seemed to open wider and she had a strange look on her face, one of apparent incredulity at what we were wanting to do. Once we'd finished, she seemed to take a few seconds to return to reality.

"I'm sure we can help you. We make all sorts of custom plastic devices, but I've certainly never heard of anything like this before."

"Maybe it could become a stock item," suggested Gloria with a grin.

Melissa pulled a funny face. "I doubt that would happen," she said, "I wouldn't want to tell the mainly male board of directors what that particular stock item was used for."

She pressed a buzzer and shortly afterwards a young man entered the foyer and was introduced as Chuck, who was the head of the design team.

"I'll let you explain to Chuck what it is you need," said Melissa diplomatically.

"Would you like to come through to my office?" invited Chuck.

His office was quite large with a comfortable couch, several chairs and a desk. He ushered us to the couch, telling us it was the most comfortable seating he had, and sat on a chair opposite us. Our short skirts rode up as we sat down and we kept out knees apart so he would have had an excellent view of our tightly strapped crotches, which was evident by the bulge that suddenly appeared in his pants.

"So, how can we help you?"

"It's probably easier to show you," suggested Gloria, standing up, "Lie on the couch, darling, and let Chuck see the problem."

I grinned in anticipation as I wriggled into a suitable position, spread my legs widely apart and pulled my skirt up to my waist. Gloria gave a running commentary as she unfastened my crotch strap, exposing my wet slit to Chuck's gaze. She then spread my lips apart, opened my entrance and inserted her finger to show how close my cervix was to the outside world. Then she explained what was required to solve this problem.

Chuck had a strange look of almost disbelief on his face, as though he was wondering whether this was actually happening or whether it was a dream, or possibly a nightmare. Eventually Gloria finished her demo with an invitation for Chuck to feel the problem himself. By now the bulge in his pants was extreme, looking like the zipper would fly apart at any second, and there was a wet spot where the head of his hard cock was obviously pressing.

"So, the main problem is that when Stan, our partner, fucks Mandy, he can't get in very deep unless he enters her cervix, but that takes time to open. So, if a plastic device could be made that will firstly lift Mandy's womb upwards or at least stop it prolapsing further, and secondly hold her cervix open, that would be great. If you like you can have a try and see what we mean."

It was very clear that Chuck was totally lost for words, his brain obviously struggling to take in the reality of the situation while two sexy women, one semi-naked, described their intimate problems to him and asked if he could design a solution. Eventually he found his tongue.

"That sounds like a good design," he replied, still looking at my exposed pussy intently.

"Have a feel and see what we mean," invited Gloria.

This time he accepted the offer (or was it a challenge?) and knelt beside the couch, tentatively reaching out his hand towards my crotch. Gloria would have none of his hesitation and grabbed his hand by the wrist and pushed it towards my open slit, sliding his fingers between my gaping lips.

"Push your fingers inside and feel how shallow she is," she told him.

He had little option but to follow her instructions and I felt him gently caress my lips then, finding more courage, he slowly pressed first one then two fingers into my entrance, pushing inside for the short distance until he encountered my cervix.

"Yes, I see what you mean," he said, "That's much shallower than the girls I've encountered in the past. So how do you have sex?" He smiled at me, sympathetically it seemed.

I explained how Gloria had dilated my cervix and allowed Stan to fuck me the previous night, but also lamented the fact that it seemed like quickies were now off the menu due to the time taken for dilation. Hence our request.

"Would you like to try?" asked Gloria, "We can see that you've got a hard problem."

Chuck belatedly and self-consciously covered his crotch, then realized the futility of his action and returned his hands to my pussy.

"Well, if you don't mind, Mandy, I'd love to have a try," he replied, his cheeks reddening in embarrassment.

"Well, then, stand up," ordered Gloria, taking control and unfastening his pants, pulling them and his undershorts to the floor. His long, hard cock bounced up and down in her face as she knelt before him. She opened her mouth and engulfed his head, causing him to groan in arousal as his hips reflexively moved back and forth. She then moved her head back and stood up.

"In her cunt, not in my mouth," she told him.

Chuck gripped the back of my thighs, lifting my hips off the couch as he positioned himself for his entrance. I felt the head of his cock between my labia, then felt him thrust inside, stopping after only a couple of inches as he pressed against my barely open cervix. He thrust back and forth several times but found that he could not make any further progress, as we had expected.

"So, now you see the problem," said Gloria. "I'm guessing that is not very satisfactory for you nor for Mandy."

We both agreed. "Right, Chuck, it's very obvious that you need and deserve some relief, so leave Mandy, I'll deal with her later, and come and fill me with your sperm."

Chuck withdrew from me and lowered me onto the couch. Gloria was on the couch and had removed her crotch strap, had her skirt up and was waiting for Chuck. He positioned himself as he had for me, inserted himself into her entrance and thrust deeply inside, filling her completely with one thrust, his pubic bone pressing against her clit causing her to let out a yelp. He began fucking her hard, withdrawing almost completely before thrusting back inside, time after time, both of them becoming more aroused with every passing second. Gloria was making soft mewling sounds while Chuck grunted with each deep thrust. Predictably, they both reached their climaxes quickly, Chuck giving a cry as he thrust himself against Gloria's pussy, holding there as his cock erupted its hot cum into the depths of Gloria's pulsating cunt, causing her to give a short, sharp scream as she climaxed on his spurting rod.

All I could do was watch and gently stroke my clit, hoping that Gloria would take pity on me when we arrived home. Their ecstasy was as short-lived as their build up had been. Chuck lowered Gloria onto the couch as his cock slid out of her hole. She quickly refastened her crotch strap to keep his juices inside herself for me to suck out later. Chuck found a tissue to wipe his softening cock and stuffed it back inside his clothing as he dressed himself again.

"Women are so lucky to wear skirts, meaning that they are much more available than men," he commented.

"I thought it was men who designed it that way," commented Gloria drily.

Chuck resumed his professional role. "Thank you for that demonstration of your requirements," he said, almost as though nothing untoward had happened, "I now have a full understanding of the problem. I'll come up with a prototype in a few days' time and perhaps you would be good enough to return then for a fitting. What I will do is to make several plugs, for want of a better term, one with a thin rod, one a thicker rod, and one with a tapered rod to allow for the cervical opening to be expanded simply by adjusting the crotch strap tension. Does that sound Ok to you?"

We agreed that it did and enquired about the price.

"Oh, you needn't be concerned about the price. We'll describe it as a new product line and we always bear the development costs of those. Before you go, I'd just like to take a few measurements. Far better to use a tape than fingers."

I removed my crotch strap again and spread wide on the couch once more as Chuck clinically measured and made several sketches of my most intimate parts. Then he gave us each a hug goodbye and escorted us to the reception foyer.

"All sorted?" asked Melissa.

"Yes, all good," replied Chuck, "These young ladies will be back in a few days for a fitting of the prototype device. Till, then, thank you both. See you again soon."

The next few days dragged. Despite Gloria's attention, I found it really hard to have a strong orgasm. I missed the sensation of a man's hard cock pounding my pussy, filling my cunt. Instead, I found my cunt was filled mainly by my own womb. On several occasions Gloria stretched my cervix to allow Stan to fuck me, which was wonderful, except that the spontaneity had gone. He could no longer simply throw me over his shoulder, dump me on the bed and fuck me to ecstasy; now it was a planned operation. I was so looking forward to having my cervix held open constantly.

True to his word, Chuck phoned three days later and we visited him that afternoon. The plugs looked amazing, solid, but light, smooth plastic, the oval outer end, designed to fit between and be held in place by my labia, being around three inches long and half that wide, curved to suit my shape. The rods were two and a half inches in length, one tapering from a rounded point to about an inch in diameter, the last half inch being parallel sided, the thin one was an inch in diameter with a rounded end for easy insertion, and the big one tapered from a rounded end of an inch diameter to two and a half inches diameter, the last half inch being parallel sided. I wondered how the big one would feel and decided that I would find out tonight.

"Right," said Chuck, "It is always the task of the designer to fit the prototypes, that way I can see what needs to be changed."

I removed my crotch strap and lay on the couch with my legs widespread. Chuck brought the tapered plug over and lubed it with a tube of water-based lube, then began spreading my pussy lips around the ball end as I felt the tip of the tapered rod touch my cervix. He inserted it easily, then pressed it slowly further inside. It was a lot easier spreading my cervix open using this tapered rod than it had been using fingers and stretching. Very quickly I felt the opening was wide enough for a cock, but he continued to push the device into me until I felt the end fitting snugly between, and being held in place by, my labia. I could then contract the muscles at my entrance and almost suck the device into me, feeling my cervix distend the final width needed to accommodate the tapered rod as the parallel sides at the widest part minimized the force of my cervix trying to contract and expel the intruder.

Chuck removed his hand and the device stayed inside me. "How's that feel?"

"It feels really good. That was so much better than fingers."

"It would have been. Do you want to stand up and see how it is?"

I stood up and let my skirt hem drop before walking around the office perfectly normally. I had expected that I would feel the rod either arousing me or wanting to fall out but neither of those happened. I commented on that and Chuck grinned. "Wait till you wear the big rod," he said. "Get back on the couch and I'll fit the smaller rod for you. It should go in easily now the cervix is partly dilated."

It did, and very soon I was walking around with the small rod securely held inside me. Gloria had taken my place on the couch and was having her dimensions measured by Chuck's penile measuring stick. As they both fucked like rabbits, all I could do was to move the outer end, enjoying what small sensations I could generate. Once Gloria and Chuck had both cum in a noisy joint orgasm, I noticed that Chuck stayed hard.

"Your turn now," he told me.

I lay back on the couch and spread my legs, allowing Chuck to remove the small rod. He gently felt inside with his fingers and found my cervix had remained dilated enough for him to insert his cock. It felt wonderful as he slowly and carefully entered my womb through my cervix until finally I felt the root of his cock pressing against my clit. He began a slow and gentle fucking motion as I felt my cervix dilating still further around his rod. This time he lasted longer than with Gloria and we gradually brought each other to a satisfying orgasms.

Once he had withdrawn, he selected the large rod and carefully pushed it inside me. Initially it went in easily, my cervix being stretched open by his cock, then it began spreading my cervix even wider until the final size was reached and my entrance partly closed over the end. He held out his hand and I pulled myself up, feeling how it felt to stand with a monster rod in my womb and cunt. It felt wonderful. Unlike the smaller rods, I could feel this one and as I moved, it moved inside me, stimulating me gently. I wondered if I could cum just from walking.

"How's that one feel?" asked Chuck.

"That feels so much better. Feels like something's inside me. I'll keep that in for going home please."

"It sounds like you need a still larger one as well, for special occasions, maybe."

"Yes, please make one of those," I replied, maybe three inches in diameter and longer, a three-inch rod maybe?"

"What say I make two, one with a three and the other with a four-inch rod just to challenge you?"

"Oooh, yes, that sounds like fun. Thank you, darling." I embraced and kissed him, then fastened my crotch strap tightly over the large rod.

When Stan arrived home, I was waiting for him, in my corset and crotch strap only. I embraced him as he walked through the door.

"Have I ever got something to show you," I said as I tugged at his hand to lead him to the bedroom. There I stripped him quickly, his cock already half hard, then lay on the bed, legs apart. "Undo my strap, honey."

He did and bent to examine my new rod, held in my cunt by my labia.

"Looks great. How big is it?"

"Take it out and check for yourself."

Stan removed the rod and was amazed to look inside my opening and see my cervix widely dilated and waiting for his hard cock. He wasted no time in mounting me and thrusting inside me, my cervix fitting snugly around his cock. He brought me to my first orgasm very quickly, then a short time later he gave me a second one, more intense than the first, before finishing me off by cumming inside my womb, the sensations causing me to scream in yet another powerful release.

We lay together, his softening cock deep inside me, as we regained our breaths.

"Oh, I needed that, darling, thank you, dearest one, thank you."

"Yes, I know you've been suffering and missing out, especially as you've been watching me make love with Gloria while being unable to do the same for you. I guess that's all over now."

"Yes, and I'm getting even bigger ones so you'd better grow your cock a bit if you want to still be able to fill me."

"I'm sure we'll work something out somehow," he replied, climbing off me, wiping his cock and balls, then, with a grin, picking up the rod and fitting it back inside me.

***************************

Over the next few weeks we worked with Chuck to design and test several more devices for female internal use. Gloria needed different designs of dildo as she was not experiencing prolapse yet, although she was gradually tightening her corset which would possibly cause a prolapse in the future. Therefore, we helped Chuck design and fine tune the dildos I was using, incorporating the clit cover and remotely operated vibrator, as well as vaginal dildos, using the same clit cover and vibrator, for Gloria.

We used these devices frequently, making up games we could play both in private and in public. One of our favorite games was for one of us to find a nice-looking young male shop assistant and to discuss whatever he was selling while the other one of us would stimulate the buyer's clit. Usually we had a five-minute limit from when the vibe was first turned on until it was turned off, the winner being either the controller, if the one being stimulated had an orgasm, or the one being stimulated, if she was able to resist the urge to cum. The loser would usually be made to cum five or six times without rest once we returned home.

In the interests of gender equality, we also had some crotch straps made for Stan. The first one was a plain strap which simply fastened to a waist belt and held his cock down between his legs while we would do our utmost to arouse him, but of course an erection was out of the question. This rapidly progressed to one which had an inbuilt tube that his cock was placed in between his legs, which allowed him to urinate by sitting down. We also experimented with the design of his straps, adding padding to position his balls where we wanted them, either forced upwards in their sockets at the base of his cock, or else stretched downwards between his legs. We could now lock him into this for extended periods, and we did this frequently, forcing him to remain celibate with compressed balls on many weekends while we either made love with each other or found willing male partners who would make love to us while Stan was watching. The result of this was that his erections became harder and the volume of cum increased as it wasn't being drained as much while he was being stimulated more.

Gloria slowly but surely reduced her waist measurement by tight-lacing a steadily decreasing size of corset. Megan supervised this reduction carefully and also kept a record of the length of Gloria's vagina from entrance to cervix. After nearly two years it was noticeable that Gloria was showing the start of a prolapse, so we asked Chuck to design a dildo that would fit into her vagina and support the base of her uterus, thus preserving her length. For a while this worked well, then gradually, as she continued to lace even tighter, she lost the battle and began wearing the dildos I had been using.
