It's a quiet day in the New World and the Strawhat Pirates find themselves relaxing, enjoying the cool, autumn breeze. They had just finished their lunch and had quickly gone back to their individual hobbies. Robin, however, found herself in a pickle. She didn't quite feel like reading just yet and hadn't yet found a replacement activity. Her first instinct was to go and find Nami but knowing what that would lead to, she decided to check up on the others first. Better be safe than sorry.

Brook and Sanji were the only two, together with Robin, that remained in the dining room once their meal was over. They were busy with cleaning the dishes, which was no easy task. Not easy as in difficult, but very time consuming considering the vast amount of things needed cleaning after Luffy had been let loose amongst the food. Robin smiled at the two and left them to their chores.

As soon as she got out, her ears got bombarded with cheers and merry laughter. Usopp, Chopper and Luffy were having a blast trying to reel in a Saber-toothed Whale Shrimp. It tried its best to get free from the hook that was stuck in its mouth, but ultimately failed as Luffy grew impatient. Her rubbery captain smacked the creature straight in the face with a well-placed punch. Poor thing didn't stand a chance.

"Sanji!!" Luffy screamed.

"He's in the kitchen, captain-san." Robin replied.

"Oy, Robin! Look what we caught! Doesn't it look tasty!?" Luffy continued.

"DON'T BOTHER ROBIN WITH SUCH REDUNTANT QUESTIONS, YOU SHIT!" Sanji shouted, who had just barged out of the kitchen.

"And here comes the pervert right on queue... You're as obvious as always, Curly." Zoro said, just waking up from his nap.

"Just go back to sleep, you shitty rail-decoration." Sanji retorted.

"What did you call me!?"

Robin just laughed at their antics and continued her walk around the ship. Shortly after escaping the small brawl that had erupted on the lawn of their ship, she found Franky manning the helm. She stopped and talked with the cyborg for a small while. Franky always had something to talk about. If it wasn't about his inventions, he would display all sorts of new functions he had included into his body.

"Is the thing I asked for ready?" Robin asked.

"Oh it's ready alright. Do you want it installed in your room?" Franky grinned.

"That would be wonderful."

"I added something extra to it, so it should be far less conspicuous."

Robin smiled and thanked him before heading off to find Nami. Thanks to the good news that Franky had given her, she was getting really excited. Robin had waited a good, long week for its completion and now, finally, she could have some real fun with her little cat. Just thinking about the possibilities, which had opened up before her, made her ache with anticipation. She could feel her crotch burn with need as she tried to subdue the growing member inside of her dress. "Where the hell is she...?" Robin thought. After a few moments of searching she finally found her resting on a chair outside of the observatory.

"There you are..."

"Oh, Robin! Are you alright? Your face is a bit red." Nami asked.

"I'm fantastic. I've been looking for you." Robin grinned and walked over to her friend.

"Did you want something?"

"I want you..." Robin replied, as she positioned her legs on either side of Nami and sat down on her thighs. Robin was lucky that the chair didn't have any arm-rests, or this would have been much harder.

"Oh my!" Nami gasped as she saw the tent on Robin's dress. "Shouldn't we go inside before we do this? What if the others find us?"

"It should be fine; they're all busy with other things. And even if someone would see us, wouldn't that be really naughty...?" Robin stated, rubbing her hands all over Nami's growing bulge.

"That does sound really fucking hot... But we should take it slowly, so we don't accidentally freak them out. It wasn't long before they found out about your new powers and our relationship."

"You're right, Nami. I'll make sure no one sees us. Now, hands to the side and don't interfere." Robin smiled and slowly began unbuttoning Nami's jeans.

Nami placed her arms to the side of the chair and allowed Robin to grow a pair of hands to hold them in place. She took a deep breath as the front of her pants was forced open, freeing her nine-inch member from its tight prison. Her cock quickly grew into a full, hard and throbbing erection. Nami moaned as the cool air blew around her penis that already dripped of pre-cum. She stared at it, watching as it jumped and twitched with need. It had been more than a week since her cock was last allowed to ejaculate. Robin wanted her in a constant state of frustration, with her balls ready to release its pent-up, boiling semen at any moment's notice.

"How are your balls feelings? Are they nice and big, full of juicy cum?" Robin asked as she scooped them out of Nami pants and began squeezing them. Each testicle was roughly the size of a golf ball at this stage.

"Ooh, they feel so tight and frustrated... It's been pure torture walking around with these hanging heavily from my crotch!" Nami replied, doing her best to keep her moans silent.

"That's good to hear." Robin placed her hand on Nami's shaft and began to stroke it gently. "We need you on the verge of bursting when we try out the new toy I have for you."

"Does that mean that I finally get to cum?" Nami moaned. Her cock was leaking pre-cum in large amounts, becoming a perfect lubrication for their activity.

"Yes, I'll allow you to enjoy the sweet release when we get to that point." Robin moved her dress to the side, letting her own dick out for Nami to look at.

"Oh thank god!" Nami sighed, feeling her lover's hand slide up and down her rigid arousal.

Robin had taken great care in teasing Nami for all this time, not once allowing her to feel any relief. She teased her daily for hours of end, forcing her to edge while Robin had gotten to cum her brains out. Her dick would have been in a constant erection if it wasn't for the tight jeans Nami had been forced to wear. Since it was through Robin's power that Nami was able to sport a stiffy, Robin had learned to control her new powers without using the rumble balls Chopper had made for her. She could easily take it away at any moment's notice. But the two of them had come to love their new members so much that Robin rarely, if ever, removed them. They had essentially become full-fledged hermaphrodites, and were now enjoying the benefits of both worlds.

Robin increased her grip on Nami's hard cock and began rubbing all over her sensitive head. The slickness of the pre-cum made it easy to twist and rotate her hand around the cock-head. Nami tried her best to be quiet, but the teasing handjob made that almost impossible. Sighs and soft moans left her mouth as she enjoyed the sweet sensation given by the archeologist. Her stiff penis felt like it was on fire and was already close to ejaculating. It was no surprise after being forced to edge every day, for a whole week.

"I'm going to cum, Robin...!" Nami tried to thrust her cock through the hand that stroked her, but Robin was sitting on her legs. She couldn't move an inch.

"And you think that I'm going to allow that to happen?" Robin gave Nami one, hard stroke before letting go.

"Ooooh fuuuck!" Nami whimpered as her cock edged on the verge of cumming. "Soo close!"

"I just love seeing you like this... Wouldn't it feel great to ejaculate now?" Robin slowly rubbed her hand over Nami's pulsating shaft, prolonging her edge as much as possible.

"I need to cum so badly...! Can't you let me cum just a little?" Nami whispered and panted. Doing this outside, but in secret, made her so fucking horny.

"Okay, sure." Robin began stroking Nami's shaft fast and hard.

"Cumming!!" Nami cock jumped and twitched, desperately trying to relieve itself. Just as her balls began to pump, she could hear an audible "click".

"Oh yes... Cum as hard as you can!" Robin moaned as she furiously stroked her own stiff member. Robin had been prepared for this and placed a cock-ring on the base of Nami's shaft. It was made to prevent the wearer from being able to ejaculate and force them to stay erect, no matter what.

Nami edged hard as her balls desperately tried to pump its cum through the ring. Her cock strained and throbbed, jumping with every pump of her balls. She gritted her teeth and whimpered as she kept edging and edging. Jolts of pleasure surged throughout her entire body, making her pussy extremely wet and excited. Sweat ran all over her body and her breasts rose with every breath she took. It was such an erotic display.

Robin jerked her meat as fast as possible. She couldn't hold back anymore, Nami's lewd display proved too much for her. Both of her hands went up and down her rock-hard member with great speed. Every time she reached her sensitive cock-head, she would squeeze down and twist her hands around it. It felt so fucking good that she almost started drooling. Her balls jumped up and down with her strokes, lightly tapping on Nami's desperate testicles.

"I think I'm going to ejaculate... Nami!" Robin moaned. "I'm going to ejaculate and show you just how good it feels! Look at my cock while I cum! Look at what you can't have!" Robin grabbed Nami's dick and stroked both of their members at the same time.

Robin grunted as quietly as she could while she came. Strings of hot, sticky semen shot out of her cock, sending it flying all over Nami. As Robin's balls were being emptied, Nami's own was forced to hold its load back and have it boil inside of her. It was an intense, agonizing but wonderful experience to ride the verge of orgasm while being covered in semen. It would make her eventual release all the sweeter. She just had to hold on and keep her sanity until that moment came.

Robin finally let go of their cocks as the last of her sperm had been jerked out. She let out a nice, long sigh of relief as the pressure in her nuts was gone. It was always such a joy to use Nami as her own, private sex toy. She turned and looked behind her, making sure they hadn't been spotted. No one had witnessed anything, but she could hear Luffy, Usopp and Chopper as they continued fishing. Her eyes turned back to find Nami trembling with lust.

"Didn't that feel good?" Robin asked teasingly.

"C-cuuum... I need to Cuuum..." Was all Nami could say.

"Fufufu... You're just adorable. You know I can't let you do that. But don't worry, Nami, we're not quite done yet..." Robin rose from her position and grabbed her balls, moving them to the side.

Nami looked up at Robin and trailed her eyes downwards. Robin's wet cunt was on display as she slowly stepped forward, positioning herself over Nami's aching cock. She could only whimpers as Robin grinned down at her. It was obvious what was going to happen next. And surely, Robing began lowering herself. Two more hands grew at the sides of Nami's head and folded over her mouth, making sure she wouldn't be too loud for the next part.

Robin gently let the erection beneath her slowly penetrate her wetness. She bit her lower lip as the cock entered her, filling her up inch by inch. Nami groaned into the hands covering her mouth as she was devoured by Robin's tight, hungry cunt. Her balls were still positioned above her legs and as Robin sat herself down, they became squeezed between her legs and Robin's firm butt.

"Oh my... I absolutely love when you this hard! I can feel your cock throb and pulsate inside me... It's so desperate to cum, isn't it, Nami?" Robin said, in her most seductive voice.

"Mmmfph!" Nami moaned.

"Squeal as much as you can my lovely little toy... I get off on it something fierce!"

Robin began rocking her hips back and forth, grinding her pussy all over Nami's trembling hard on. Her ass squeezed her lover's testicles as she rode over them. Robin cupped her breasts in her hands and began massaging them, giving her hard nipples a few, quick pinches. She raised her hands above her head, holding them together and began rotating her hips. Back and forth, up and down, left to right and right to left. It was like she as giving Nami a belly dance, in the form of tender fucking. Her own cock swayed in the air as she moved.

Nami groaned and moaned almost continuously as her cock was being worked on by Robin. Every second of this passionate sex was like pure torture. She whimpered and trembled as she was stuck on the verge of cumming. The ring around the base of her penis made sure of that. Fuck... What she wouldn't do to get some release!

"Oooy! Robin, Nami!" Luffy shouted.

Both of their hearts skipped a beat at the sudden call from their captain. Robin quickly removed her limbs holding Nami and scooped her tits back into the jacket and closed the zipper. Just as Luffy came up the stairs, Robin closed her dress as best as she could and let her hard cock vanish into thin air. Both of them tried to act as casually as they could while Luffy approached them from behind. Poor Nami had to try a little harder however, as Robin still had her dick inside of her.

"Have you guys seen the cool fishes we've caught!? They so funny! We got one with a nose that looks just like Usopp's!" Luffy cheered, holding up a very ugly fish.

"That does look like Usopp." Robin replied. "Don't you think so, Nami?" Robin grinned slightly as she began rocking back and forth again. She made sure it didn't look too suspicious.

"Hnngh! I-I think... It does look like U-Usopp's nose..." Nami replied.

"Is something wrong with you, Nami?" Luffy asked. But just at that moment, Robin grew a dozen of tongues on the inside of her slick pussy and began licking all over Nami's twitching cock.

"Ffffuu...F-fine! I-I'm fine, I mean!" Nami really did try her best not to give away her predicament.

"Are you sure...? It looks like you have a fever."

"Y-yes! I'm fine. R-Robin is just very heavy!" Nami couldn't help but to moan as her cock was ravaged by Robin.

"Oh, so I'm heavy, am I?" Robin smiled creepily as she looked down at Nami. Robin rose slightly and slowly sat back down, squeezing the life out of Nami's rock hard member.

"Ooooh fuuuck...!" Nami grunted.

"You guys are weird." Luffy said, scratching his head. "Hey, Nami. What's that on your face?" Luffy pointed at the white stuff on Nami's face. Nami's heart stopped for a second, she had completely forgotten that Robin's cum was all over her.

"That's just special cream, captain." Robin stated. "Nami is a bit of a sloppy eater and I was just about to help her clean it off."

"You've been eaten sweets without me knowing!?" Luffy fumed. "That Sanji needs to stop sneaking food to you guys without telling me!"

Luffy then suddenly reached out with his hand and scooped up some of the stuff with his finger and put it in his mouth. Both Nami and Robin almost forgot to breathe as they witnessed what their captain just did. It was so fucking hot though! Robin nearly came right on the spot as she was still licking away at the cock in her pussy. Nami could feel how Robin clenched down on her throbbing member, forcing her through another intense edging.

"This tastes good! It's really sweet!" Luffy cheered. "I'm going to have Sanji make some for me too!" And so Luffy rushed off towards the kitchen, hoping Sanji could whip him up some nice, tasty cream.

"I'm kind of happy that I'm not capable of recreating actual semen..." Robin stated, watching the cheerful captain leave. "Now... Where were we?" Her wide grin turned back to the quivering Nami.

Robin grew back the limbs she removed earlier and locked Nami up in her embrace once more. She immediately began hopping up and down that wonderful, hard, locked-up cock. Their encounter with Luffy had aroused her to no ends. Robin leaned over her groaning lover, took away the hands covering her mouth and kissed her. Their tongues met and danced as she slammed her pussy down on Nami's dick. She could feel her orgasm approaching quickly, and in the heat of the moment, Robin raised her dress above her ass.

Anyone who would walk up those stairs would get a perfect view of Nami's stiffness being eaten alive by Robin's tightness. They would see her ass slam down on the navigators balls over and over, spilling her juices all over them. Not that Robin would mind. She secretly hoped that at least Franky could see them go at it, even with the mast being in the way. And even if no one could see them, she was sure that at least someone could hear their muffled moans. The thought of getting caught drove her wild with lust. Her orgasm was approaching quickly now.

"Cum with me, Nami!" Robin moaned as she broke their kiss. "Fill me up with your huge load!" Robin dove back in, continuing their kiss. She knew that Nami couldn't cum, but fuck did she enjoy teasing her.

With a final thrust, Robin drove her pussy down on Nami's penis and came hard. She moaned into her lover mouth as her vagina clenched around the stiff rod. Poor Nami could only lie there and feel Robin cum all over her cock. Her balls felt like bursting as the pleasure drove her insane. Her eyes began to roll backwards as she edged and edged. Her rock hard member throbbed and twitched inside the constricted space of Robin's orgasming cunt.

Robin was in heaven. Her orgasm continued and just wouldn't stop. She felt so happy and lucky to have found such an amazing lover. She had to give back as much love as she could, Nami deserved no less. Robin could feel her orgasm slowly begin to fade. Her eyes closed as she lost herself in the haze of lust. She could just fall asleep right then and there, but their location made that impossible. A few moments later, Robin released Nami from her restraints and slowly stood up.

Nami's cock gently slid out of her, springing back to its natural position. It smacked her on the stomach and made a sloppy "splat". Robin looked down on the navigator, marveling on her work. The poor thing was still edging her brains off as her cock kept jumping and twitching in the air. Robin would have kept fucking her if it wasn't for the fear of accidentally breaking the poor thing.

"Oh my... Aren't we enjoying ourselves?" Robin said as she fixed her clothes.

"Ooo-ooh... Aa-ah... C-cuuum... W-want... T-to cuuuuuuuuuummmm...!" Nami muttered. She was shaking from the intense pleasure.

"Oh fuck..." Robin moaned. "I better not grow back my cock until I'm out of sight, lest I want everyone to see how hard I would be. Hmm... Now that I think of it. What should we do about you? I obviously can't take away your wonderful stiffy either. You would lose all that tasty sperm and frustration that we've worked so hard on for the last week. What do you think?"

"C-cuuuuum! I n-need to... C-cuuuuuum!"

"Fufufufu..." Robin chuckled. "Is cumming all you can think about?"

"Cuuum!" Nami continued to groan.

"Hmm... I should leave that ring on you for now. Don't want to risk you having an orgasm when I'm not watching. Better yet... I should just leave you here; have you edge and throb with the risk of getting caught." Robin slid her hand down and into her dress, rubbing her clit as she teased her lover. "And I doubt that you'll be able to get your cock and balls back into your pants when they're like this. But isn't that great, Nami? You'll have to walk around, unable to hide your perversion." With those last words, Robin removed her hand from her crotch and turned around. "I suggest you hide out in the observatory once you've regained your strength. I'll come get you once Franky has installed our new toy." Robin grinned as she walked away from Nami. She blew her a kiss as she disappeared down the stairs, leaving the navigator to lie helplessly on her chair and edge.
