I used to be named Kevin. You read that right. I changed sex a little more than a year before this story begins. Changing sex wasn't my idea. The Juve...nile Court called it "temporary feminization." The recently invented Unified Field BioConcentrator had made it possible. My new body was two inches shorter with B-cup sized breasts. Everything was perfect: hormone balance, skin, voice, and skeleton. I even had a womb and ovaries.At first, the prospect of being a girl horrified me, even though it. Daddy whispered in my ear, “Can I use your special position with Sammie?”“That outfit just screams, bend me over and fuck me from behind, doesn’t it? Go ahead, daddy. I couldn’t resist her either.”Daddy bent Sammie over the edge of the bed, lifted her skirt, and rammed his hard dick into her wet cunt, just pushing the thong out of the way with his finger. I got so horny watching daddy slam his cock into Samantha’s little pussy. My twin getting more worked up than usual as daddy pounded her. In all the shenanigans last time, I didn't get the chance to feel my cock inside her; this time, I was cataloguing every sensation. She started moving up and down, grabbing my cock with her pussy muscles. Every so often, she'd rotate her hips, adding a little grind to it. After a few minutes of that, I was in heaven......until I heard an exaggerated clearing of the throat. I looked up, and couldn't believe what I saw; in fact, in hindsight, I still can't believe what I saw. Linda was standing. Your arm is draped over her bare shoulders. Her large breasts are in a tight black halter, her exposed midriff going to tight black leggings and sneakers. Next to you in sheer lycra and short silk the effect is devastating. I kiss you, feeling your firm nipples through your almost transparent top. I run my tongue over your beautiful lips, and you move in close to whisper in my ear.-I'm being a bad girl-I smile, -Really?-You nod, and look at Tonia. She's grinning, very high.You gesture over.
