The longer Andy's dick was in my virgin anus the better it felt...I couldn't deny that. When he began thrusting I actually felt the emptiness inside me and I longed to be stretched around him again. This body really was meant for sex and sex alone, I managed to find everything, even this, to be totally pleasurable. And it seemed like his cock was keeping me from my embarrassing gas-passing for the moment, so at least my butt and tits would stop growing...
A sharp spank brought my full attention back to him. "Mmm! You're having fun huh? Maybe I should step it up a little?" His thrusts got harder and faster, my absurd body squirting milk and pussy juices all over the bed, and I had just showered too...not to mention the sex had be sweating bullets, I tried not to picture a big draft stallion with sweat steaming off his powerful body...and failed.
I squealed with orgasm, locking me in that body for another day. I was up to three days now, today plus two more for each time I came. Fuck...this wasn't going to be easy. Not only would I have to keep myself from cumming, not to mention sex entirely if just anal can make my jizz, but I would have to do it while in this body for the better part of a week.
My tailhole clenched and pulsed wildly around his cock, no doubt spurring his orgasm. He gripped my haunches (damnit...still referring to myself in horse terms) and grunted and shuddered while filling my rump with hot semen. Instantly I began to shrink, my tits -spraying- out milk as they shrink back to the plump B-cups they were before, my hips and butt retracting with Andy still inside me. "Ooooh shit! Y-you're getting so tight!"
My (now) slender hips wiggled as he drew himself from me, his cock flesh was red with arousal and covered in sticky cum. Jesse might've made me a slutty mare, desperate for horse-cock, but a human shaped one seem to do just fine. I looked at it for only a second before taking it into my mouth and licking it clean, tasting his flavor mixed with my own tailhole's... I was disgusted, but he seemed to enjoy it, which was enough for me.
My head cleared a little after I finished, and I noticed my hands had returned! No longer hooves at all, but slender little human hands, albeit covered in plush fur. I swished my tail back and forth and sighed with relief, steadily reminding myself that I better not masturbate at all. These rules...they were getting confusing. How was I ever going to get back to being a male, let alone a human!
Andy sat down beside me, still naked, but then again so was I. "Hey listen, thanks for that...I know you're going through some crap right now, but that was great and it seems like it helped a little?"
He was right, even as he slipped an arm around my shoulders and grabbed both of my breasts roughly. "H-hey!" I squeaked.
"Oh relax, I'm done. And besides I have to get to class."
"Oh shit! M-Mas...uh Jesse told me to go to class!" I almost called him Master again, this was getting bad. Hurriedly I dressed myself, trying to ignore the sensation of my panties sliding up my thighs and cupping my unfamiliar nether region. I also skipped the bra, I knew it was only a matter of time before my breasts started swelling up again.
"Whoa whoa whoa, just because he told you to, that doesn't mean you HAVE to babe." Andy was making sense, but for some reason I had to ignore it. I -had- to get to class. I slipped up my uniform skirt and zipped it, then hastily buttoned my shirt and tucked it in. I blushed when I looked down. My chest was plain as day, dark nipples and dark fur showed right through the thin white shirt, and without a bra there was nothing left to the imagination. I should have changed into a bra...but I didn't. I flicked my tail out from the top of my skirt and headed out the door.
I can't imagine how that looked to Andy, I felt so bad...maybe if I blew him later he would forgive...oh shit! I'm thinking like a slutty little mare again!
"That's because you are one..." said a voice in my head.
