As Ty sat up, groaning, he once again reached up and fondled his hefty tits. Bouncing them in his palms, he contemplated what else he could do.
Looking over at the nude blonde runner, an idea came to him.
"I wish that my breasts will shrink down to an A cup, while the woman I am currently looking at has hers reduced to a flat chest."
Instantly, both of their boobs started to deflate, seemingly being sucked inward. Soon, Ty had tiny A cups, while the runner just had tiny, pert, and erect nipples on her chest.
"I now wish that every time I have an orgasm, both mine and the woman's boobs will grow one cup size."
Trotting over to the blonde, Ty kneeled down next to her as his cock grew to full size again. Quickly plunging it into the runner's silky fold, he started pumping rapidly. Within seconds, he came, pumping more hot seed into the woman's womb. As he was still buried to the hilt in her, both of their chest started to tingle, before pushing out a few centimeters. Ty now had B cups, with the blonde having AA cups. Again, he started thrusting. Over and over he came, each time their busts pushing out just a bit more. Soon, Ty had large F cup tits, with his 'partner' having E cups. It still wasn't enough though, and Ty increased his pace, not even letting himself have more than a few seconds between orgasms. Their tits exploded outward in size. Before long though, Ty simply could not do any more and collapsed onto the blonde's squishy chest.
Ty now had massive H cups, while the blonde had G's. Groaning, Ty sat up and pulled out, jerking as he orgasmed again. His chest pushed out a bit more, ending in HH cups, with the blonde's being GG's.
