Let me begin with a warning, this story is nasty. It will involve lots of "bathroom" play as well as nasty kinky sex. If scat or pee play are not your thing, I suggest you read some of my other stories. Thank you for taking the time to read this.

***

All 3 of us are slowly waking up, my mum, my sister and me. My name is Julie and I am an 18 year old CD sissy. Both my mother and sister have been training me to act and look like a woman and as a result of that I am actually quite pretty.

What just woke us up was piss. After an especially nasty session, the 3 of us laid down on the bathroom floor exhausted from a session where they taught me how to suck cock and as we laid there, we all pissed ourselves. We fell asleep in a nice warm puddle of piss, but when it cooled it woke us up.

We were all naked except for stockings and garters which Mum insisted we wear at all times. The reason why she insisted on this was because Mum used to work in a whorehouse and her "clients" loved that look. So Mum made Becca and now I wear them 24/7. Mum took control and tossed us nice warm towels and told us to dry ourselves.

I looked at Becca my sister and said "Won't we still stink of piss?"

She giggled "Of course we will, but that just makes things so much kinkier."

"Ok Becca, get your sister prepared while I get all that we need." Hearing her call me Becca's sister made me realize that the fact that I loved being called a woman! With that Mum left the bathroom and took me into the bedroom.

"Mum is going to teach you how to fuck like a proper sissy Julie, so sit on the bed and cross your wrists dear." I did as I was told and Becca used leather cuffs to tie my wrists in front of me and then directed me to lie down on my back. She then brought my wrists above my head and tied them to the headboard.

Mum came back inside and handed Becca a different dildo than before. It was just as long, but plastic and was black. Mum giggles "I developed quite a taste for black cock at the whorehouse dear. Your Dad would probably disown me if he knew how many black cocks I had inside me."

Then she looked at me and said. "Julie, your sister is going to fuck you now. Being tied like you are now will make the fucking even more erotic for you. On one hand you are being forced to do this, but on the other hand when you are getting fucked you are accepting your new role as a woman."

Truthfully I was not certain I understood, but trusted them both and simply surrendered to what was going to happen.

"Bring your knees to your tits Julie." I did as Mum told me to do and then feel her warm fingers in my bum. She was lubricating my arse and I loved every second of it. Just then Becca came back inside and I saw the black dildo hanging lewdly between her legs. I knew in addition to the 8 inches of she cock hanging out, there was another 8 inches of she cock pressing into my sister's cunt.

My mum continued to work her lube covered fingers inside my arsehole. "When I was a whore dear, I could get men off just my using my fingers in their bum like this." I knew she was right because she had me right on the edge. "Mummy is just going to sit down and watch this sweetie." With that she sat down in a chair spread her legs and pushed a nice sized vibrator inside her cunt and turned it on. Soon the room was filled with the sounds and scents of the vibrator getting my mother off.

Becca knelt on the bed and placed the tip of the she cock by my arsehole. Being tied and having my knees to my tits made me feel so helpless and totally vulnerable. I loved it! Then I could feel the she cock starting to violate my arsehole. At first it hurt, but my sister went slowly and soon the pain turned to pleasure. I could smell the scent of the piss on both our bodies.

Finally my sister had her she cock buried all the way inside my arsehole and I looked into her eyes. Now I understood what my mother meant before. Being tied like this meant I could not resist being fucked, but the minute I saw the love in my sister's eyes I knew this was exactly what I needed.

She leaned over and tenderly kissed me. "Are you ready for this sweetie?" I nodded and then she started to fuck me. At first it was slow and loving but soon changed and she fucked me hard and fast. Suddenly she screamed! I did not realize why she screamed until a second later I felt the she cock in my arsehole start to vibrate. I glanced at Mum and saw she had a remote control on her hand. First the part in sis's cunt started to vibrate and then the one in my arsehole did too.

Mum continued to increase the speed of the vibrating she cock and soon my sister was lost in the throes of an intense orgasm. As she came I felt something warm on my face and realized I was cumming too. Being bent over like that caused me to cum on myself.

After a bit we came down from our sex highs and Becca leaned over and licked the cum from my face. She slid the cock from my arse and then walked to the side of the bed and placed it by my face. She smeared the cock on my face and I could feel shit from the she cock streaking it and then she told me to open my mouth.

I did so and she put the cock in my mouth and I started to lick it clean. After it was clean, I continued to suckle it, all the time driving it into her cunt. Soon she shuddered and I realized she had a nice mini orgasm. Mum came over and told me I looked good with shit smeared on my face and then shocked me when she licked it off.

Becca laughed at my shocked expression. "Mum is weird Julie, she won't fuck either of us, but she will lick our shit." I looked up and was obviously confused. "Tell her Mum."

"When I was a whore I developed the habit of scat play. I found out how erotic it was. It is almost exclusively done by women dear, either they are submissive and want to be shit on, or they are dominant and assert their dominance by shitting on the girl under her."

I was almost too scared to ask "Have you and Becca done scat play with each other?" They looked at each other nervously and then giggled and nodded yes.

Becca said "I thought Mum was crazy when she suggested it, but I tried it. It is so intense and sensual. I know it is not for most people, but we love it."

I looked at my mother and said "Mum, if it is mostly a female thing, shouldn't we try it? After all, aren't I a woman now?"

"If you really want this dear, I would love to, but please think hard."

The answer was easy, after everything I have done with my sister and mother, there was no doubt in my mind that I wanted to try it. Becca went into the bathroom and sat on the toilet with the vibrator while Mum untied me and then directed me to lay on the bathroom floor. The floor was still covered in our piss from earlier and even though it was cold now, it still felt so erotic.

Mum straddled my body with her arse inches from my belly. She looked directly into my eyes "You can still change your mind Julie."

I knew what I wanted and begged her. "Please Mum, shit on your new daughter."

With that my mother started to undulate her body until I saw her arsehole start to open wide. All the while my sister was fucking her cunt wildly with the vibe. I was mesmerized by the sight of her pretty brown arsehole opening as the shit started to push outwards. I was surprised that there was not a foul odor which made it even nicer.

"Sweetie, Becca and I thought you might want one of us to shit on you dear, so we eliminated spices from our diets recently to reduce the foul smells." When I heard how considerate Mum was for doing that I started to cry softly.

The sensation of her warm shit dropping on to my belly is indescribable. Her eyes never left mine as she started to bear down again. Once she finished shitting there was a nice warm mess on my belly. Mum changed position so that her arsehole was over my face and then lowered herself. "Clean me sweetie."

I never hesitated and push my tongue deep into her arsehole to clean her. As I did that, I could feel my mother smearing the soft, warm shit all over my belly and tits. As I cleaned her, I felt her fingers wrap around my rock hard cock and she started to bring me to an orgasm. Becca was out of her mind watching us and came multiple times while sitting on the toilet. When I came, I kept spurting over and over again making a mess all over my belly.

Becca got off the toilet long enough to squat over my belly and piss on it. Mum reach over and spread the sensual mix of piss, cum and shit all over myself and then reach over to smear it all over Becca's tits. Becca did the same thing and finally my mother pissed on my face.

"You two clean up now and then get to bed." Mum got up and left for her bedroom and soon we heard her shower on. Becca curled up next to me on the bathroom floor and just held me. The warm shit squished between our bodies as we lay there, both exhausted. Finally we helped each other up and went into the shower and got clean. I took out a mop and cleaned the bathroom floor.

Once everything was clean and fresh smelling (us included), Becca and I snuggled into the bed together. Neither one of us wanted to sleep as we played in our minds everything that just happened. I was confused. Mum would do things that were considered by many to be vile, yet we all enjoyed it immensely. Mum would shit on us both, but would never actually fuck either one of us.

With all of this confusion, I would utter the words that would change so much of my life.

"Becca, we have to talk."

What we talked about and the answers I got will be revealed in the next chapter.
