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.
