Kyle moaned, his mouth full of Jeff's big, meaty cock. Kyle's tongue worked Jeff's manhood over good, and he never remembered being harder than he was now. With every beat of his heart, Jeff's cock throbbed in Kyle's hot, wet mouth. Jeff moaned, then commanded, "Deep throat."
Kyle immediately took Jeff's shaft in all the way, his nose pressed firmly against Jeff's pubes, chin against Jeff's balls. Jeff moaned some more, reaching his chronivac and pressing enter for a preprogrammed transformation for Kyle.
As Kyle continued pleasuring his boyfriend, he felt his hand brush something on his face as he stimulated Jeff's balls. It was stubble - gay girly twink Kyle was growing some stubble. He didn't question it, it felt sexy and it seemed to be turning Jeff on even more.
Between moans, Jeff started telling Kyle what was happening to him. "You're growing a beard. But it won't be the blonde color of your own pretty air, it will be the chestnut brown color of my crotch hair - an exact match. Anyone who sees your beard will know it spread from my crotch to your face while you were sucking my cock and balls, and will know you're a complete bottom cocksucker without having to ask a single question.
This time Kyle moaned. He nearly lost it again at the new reality that everyone who saw his twink face with its brown beard would know how he got it from what he was doing right now. Kyle's little cocklet drooled and Kyle felt a tingling deep in his ass (boipussy). His passion grew even more as he sucked on his boyfriend's big mushroon head and throbbing steel shaft, enjoying the taste of his boyfriend in his mouth. He didn't realize his intelligence would leave him the next time he came, and that he would really be a dumb blonde; even if he knew, he wouldn't care, he just wanted to please his man.
Jeff was about to cum and pulled out. He started playing with Kyle's boipussy, and Kyle's moans grew louder, clearly she was in heat. Jeff would fix that.... his cock slid into Kyle's bubble butt, well-lubed with Kyle's own spit. In and out Jeff pistoned his girl's tight little ass. "We're gonna cum together this time," Jeff breathed heavily, nearly there. Kyle was right there with him, her heartbeat pounding with excitement.
Then with a gush, both boys came powerfully, Jeff holding the more delicate Kyle in his big, strong arms, kissing one another in passionate embrace. Finally, they collapsed into each other's exhausted arms, breathing heavily, feeling closer than ever as they rested in the quiet darkness.
Somehow Kyle knew what the final change was. His boipussy was a real boipussy now. He could get pregnant, and he knew it was Jeff's desire to keep him barefoot and pregnant from now on.
