Daddy's Little Girl

I decided it was best to do as my mother asked. After all, maybe I would really like it. I was one sick bastard anyways, so pretending to be a chick wouldn't be too bad.
"Okay mommy," I said. "What do you want me to wear?"
She handed me her thoroughly soaked panties, and bid me put them on. I stripped of my pants, and she removed my shirt, until I was completely nude. One legt at a time, I slipped her dirty, spent panties up and tightly around my dick. She helped me put on her bra, then stripped, and put her clothes on me.
Then, the evil glint returned to her eye.
"Come here, girl," she said. "Sit on your daddies' lap." I could only obey, the panties dripping through her clothes. I was about to burst forth again as well, but mom swatted me. "You've been a dirty girl. Take off those pants and show me your underwear."
I could only do as she asked, and as soon as I had stripped, she started to slap my ass. She counted each time, and after each slap, suggest her dick was hardening. When she reached ten, she turned me over, and looked down. Then she said, "Well baby girl, I'm gonna have to fuck you."
She tore down the panties, and started humping me between the legs. As she grinded against me, I came, my jizz shooting up into her face, and dripping back down once again over her tits. She seemed to get off, or near enough, soon after that.
"Good girl," she said, and stroked my hair.
Then, she got up, and gathered her clothes. She stuck them in the washer, and grabbed a new outfit from the rack.
"I'm going to take a shower," she said, and left me standing naked, except for her bra.
