My mother, sister and I just finished an intense and kinky scene involving scat and piss play as well as some very good fucking. Now my sister and I (I am Julie, my sister is Becca) are lying in bed snuggling while our Mom (Linda) is in her bed alone. I am a sissy CD that my mother and sister have been helping to find myself and become the woman I was meant to be.
A key question had been nagging at my mind and finally I knew I had to ask my sister. "Becca, why is it that Mum will do nasty things like piss and even shit on us, but will not allow any fucking between her and us?"
My sister rolled over and looked at me. I could not help but look at her 36D tits peeking out from her nightie. "Look Julie, I really want to tell you why, but it is not my place to do so. Tomorrow morning Aunt Patti is coming to meet her "new niece" and I think things will become clearer than. But I have to warn you, what you will learn and see will be very intense."
I had to laugh "More intense? You and Mum have changed me from a brother and son to a sister and daughter. All of us, you me and Mum have shit, pissed and spit on each other. You have fucked my arsehole with a long nasty dildo that started to vibrate while we fucked. All the while we are doing that, Mum is sitting in a chair using a nasty looking dildo in herself as she watches us fuck. Now you are telling me it will be more intense?? I am sorry Becca, but that is impossible!"
Becca smiled and slip her knickers down to her knees and rolled on top of me and put my cock inside of her damp cunt. As we started to enjoy a slow sensual fucking she asked "Do you know what a submissive is?"
I nodded and she continued "Mom is a submissive and Aunt Patti is a dominant. All of that stems from what happened to them when they were young girls. Tomorrow you will see all of this play out. Just do me one favor; keep an open mind. Mom will be looking at you constantly, if she sees looks of disgust in your eyes, it will ruin everything."
I did not understand but promised I would be open-minded. Just to show how open minded I really was I shot a whole load of cum into my sister's cunt. She rolled over on to her back, spread her legs wide and brought her knees to her tits. "Clean me." I happily lapped my cum from her and we spooned each other to sleep.
The next morning our mother came in and playfully slapped our arses. "Okay girls get into the shower and then into your Sunday best. Julie, make sure you put your silicone tits in, I want your tits to look as nice as your sister's tits are."
We went into our large shower together and both pissed and shit in front of each other and then let the water rinse us clean. When we got into the bedroom, Mum had already laid out my clothes; matching red lace knickers and bra, red garter belt and stockings. Once I put those on I looked in the mirror. I loved what I saw. I saw a pretty young girl dressed like a cheap slut. Then I put on a dark blue dress which gave me a much more elegant look.
My mother came in and I saw she was dressed in a black dress. My sister was dressed in short black dress with leather boots. Had I not known it was my sister, I would have thought she was a dominatrix that loves to use and abuse people.
There was a knock on the door and my Aunt Patti came inside dressed just like my sister. The minute she walked in my mother dropped to her hands and knees and crawled to my aunt's feet. As she crawled I could see she was also wearing red underwear. After kissing my aunt's boots, my aunt told her to kneel quietly.
Aunt Patti walked over to me and looked into my eyes. Without thinking, I lowered my head submissively. She looked at my sister and smiled. "You were right Becca; she lowered her head immediately. She is a natural submissive."
Becca slapped my arse and pointed to her boots. Without thinking I got on my knees and kissed Becca's boots, as I had seen my mother do.
"I am not pleased with how you look, both of you take off your dresses." Not daring to upset my Aunt I crawled to my mother and unzipped her dress as she did the same to mine. Once the dresses came off we knelt side by side in our matching red outfits; 2 submissive sluts dressed in red knickers, bra, stockings and garters.
