My step-sister and I were fooling around behind our parent's back years before they got divorced.
I heard her in the bathroom laughing quietly as she bathed. My step-sister was just 20 now and had that sexy look at her. And had a nice ass and her tits were filled out with real boobs.
I would get a hard-on looking at her sometimes. She would always give this kind of 'fuck me' look at odd times.
She had more than once walked in while I was in the shower and squeaked at my cock and once she came in while I was standing there with a hard-on.
I told her that is what boys put inside pussies, and she laughed and dug at her pussy for a quick second and ran out of the room.
The door was open just a bit, and. Let I stood there, not believing my eyes as I watched her fingering her slit. My cock sprang up like it was on a switch and just got turned on. I stood there watching as she got into it, moaning some and closing her eyes as her fingers worked their magic in that young virgin cunt.
Then she opened her eyes and looked right at me. "I see you, I know you are there."
"Well, so what, I caught you fingering yours, and you can't say anything to anyone," I answered back, stepping into the room, my 8-inch cock in my hand.
"See, you're doing it, too," she laughed. "That is a nice big hard cock, just right for fucking," she laughed again.
Good thing Mom and dad were out for the night, or we would be in a lot of trouble, I thought.
"You can see how hard you make my cock, let me see your pussy," I shot back at her.
"Get in the tub with me," she said, seriously. "I can play with your cock, and you can play with my pussy, then. It is nice and juicy."
I stripped off the rest of my clothes and climbed in. Sissy made straight for my cock and started to stroke it with her sweet hands. I lay back and moaned for her.
"Wow, this was so great."
I lay there for a few minutes while she explored my cock up close, then she smiled and said, "This is what I saw mom doing with dad's cock."
She brought her lips to it and began to kiss and lick it, finally sucking it into her little mouth and stroking it at the same time...
I felt all the blood go out of my head and finally pulled her off my cock because I wanted to get to her pussy before she made me shoot my load.
