The First Treatment

June spreads my ass cheeks wide as she starts to press her massive cockhead into my asshole. Where was she hiding that thing, it must be bigger than her fist? Her strong hands keep me in place against the inspection bed as she pushes the tip inside of my ass, putting my leaking pecker on high alert. "Ohh fuck!" I yell. "Why does that feel so good?"

June replies. "Sissy likes? Just wait until you fully transition; you'll love having all your holes filled." June's massive cock slowly pushes into me. I can't resist as my ass swallows up more and more of her thick shaft until she bottoms out with a final push and a bit of precum pushes out of my fully erect cock. I feel so full. "How does it feel to have 13" of my thick cock spreading out your tight little boy pussy?"

"Fuck! It feels good, but I think we should stop. I want to stay a guy." I must be smart about this.

"Oh!? Alright then..." June says inquisitively as she pulls her massive cock slowly out of me and the elated high I felt now just feels emptier and emptier until her cockhead is once again pressing at my entrance. My cock deflates once again and I wonder what one more thrust would feel like. One more thrust won't hurt. Right?

I shove my ass back onto her cock and, oh shit, it feels so good to be filled again. I can't help when my tongue sticks out and I start to cum already. "Ooooh, fuck!" I pinch my nipples and scream.

"That's what I thought, Lukie..." June grips a hand around my neck and pulls my face up to hers. She looks so beautiful and fierce, her piercing blue eyes and shimmering grin. She grips my puny, one-pump penis and fingers my balls as cum drips onto her fingers. "You've always been a sissy slut. You just didn't know it yet." She brings her hand up and feeds it to me. "Eat it up, because you'll be tasting a lot more of this." I lick my cum off her fingers, weirdly enjoying the taste.

Then, she starts to hammer into me. She slowly builds, but grips my ass and neck tighter as she thrusts all the way in and out of my greedy ass. She whispers in my ear as she fucks me mercilessly, picking me off the ground with some stronger thrusts, "You probably thought you were an alpha, but you were just a beta-cuck boy-toy waiting to be turned into a full blown slut. Now is your reckoning, Lucas."

June penetrated me violently for several minutes before she effortlessly picked me up and fucked me face to face. She was still so radiant. I could hardly believe it was her coke-can-sized member slamming into me as my tongue hung from my mouth and dribbled spit all over my chest. Her shirt was now splayed open and her massive tits bounced up and down as she pierced into me. I came a second time, spraying jizz all over my chest before her girth felt tighter in my ass and she exploded inside of me. Her pulsing member shot into me over and over until I could feel my stomach expanding from all the cum.

She held me aloft even after she had stopped cumming and jizz dripped out of the cock that held me up and kept me full. "Good sissy. Now watch." She said as she pointed with her eyes down at my crotch.

The tummy full of jizz felt good, but I could feel a tingling feeling as it started to absorb into me. I saw my cock shrink a few inches, losing girth and length even though the erection wouldn't go away. My balls pulled up into me and my skin started to pull away, forming a tiny little pussy, big enough to stick two fingers into.

As she cradled me, my hips pushed against her arms and my ass expanded, giving me a real booty. My breasts started to swell out until I had fist sized breasts that pressed against hers. Lastly, my stomach full of cum finished shrinking and my waist curved in and then out... Not only had my proportions changed, but I felt smaller in general.

She set me down on my back and pulled her wondrous shaft out of me, allowing a little more jizz to spill out of my asshole. My cock deflated and my smallish tits bounced as I lay back. It was too much all at once. What the fuck just happened? I feel my nipples and new pussy and they tingle with energy. Is this me?

"How was the first treatment? How do you feel?"

"I feel..." I stopped for a second because my voice sounded an octave higher. "...Fucking horny. What the fuck!?" I felt up my hips and shivered as my fingers glanced over my new vagina.

"Well, I came a lot..." She replied, stroking out some cum from her still erect cock onto my newly formed pussy and rubbing it in with the tip. She gave me a sexy smile as she parted hair from her face,"...so you might be in stage 3." Her cock head felt smooth and way too large for that hole.

"Ready for another treatment?" She picked her huge cock up and smacked it against my more shapely midriff.
