"Fuck I love these huge boobs!" Nick growled, palming the huge orbs with his big, rough hands, giving them a firm, appreciative squeeze. Ty moaned softly, his brain buzzing with pleasure as he felt his new chest get manhandled by his massive boyfriend. Nick leaned in, kissing both big melons, sucking on the jutting nips Ty had given himself. The former male was thinking of himself more and more as a female, and it confused and excited him.
Nick pulled up off of Ty's chest, and raised his huge arms and flexed. They mounded up magnificently, each arm as big around as a basketball, just like Ty's boobs. "Mmm... you're so big!" Ty purred appreciatively, reaching up to run his hands over one of the huge, tense bis that Nick was showing off.
"Yeah," Nick agreed, but there was a tremor of doubt in his voice, "But your boobs are just as big! All of a sudden, I don't feel quite so huge..."
"I thought you would like it if I had big knockers!" Ty protested, pulling away from Nick's flexed arm, reaching to cover his breasts with his hands--or at least what little he could.
"No babe, I do!" Nick replied quickly, dropping his arms. He grinned reassuringly. "I love to feel 'em, squeeze 'em, kiss 'em, suck on 'em..." Ty felt relief as Nick rattled off all the ways he loved those breasts. "I think your boobs are perfect, Ty! Big and round and that perfect mix of soft and firm..." Nick reached forward, and ran his thumbs across the soft, smooth flesh of Ty's basketball-sized breasts.
"So what's the problem?" Ty asked, becoming confused.
Nick sighed, and his huge shoulders slumped a bit. "It's just, well, it was so fucking HOT when I was this massive brute, and I was bigger than you in every way! I mean, I love your new boobs, they're perfect! But man, I don't feel quite so big anymore..."
"Well, I could make them smaller," Ty said slowly.
"NO!" Nick replied quickly and vehemently. "No, Ty. They're amazing. They're hot. They drive me crazy!" He gently pushed Ty's hands to the side so he could grope both big boobs at the same time, showing his affection for them.
"Well, I think I have a solution then," Ty purred.
Before Nick could inquire further, he felt his body begin to tremble all over. His height began to increase, adding three inches, taking him up to a looming six-foot-nine. He gasped as his muscles swelled once more, pound after pound of pure brawn slamming into him, his musclefreak physique ballooning to 500 pounds of solid muscle. His dick added an inch, bringing it up to an inhuman 14 in total.
"FUCK YEAH!" Nick roared, raising his arms and flexing hard, grinning broadly as he watched his biceps rise, his arms now clearly much bigger than Ty's prodigious breasts.
Ty smirked at his boyfriend's savage joy. Slowly he spread his legs. "Look down here, lover," he purred. Nick saw Ty's pussy. He immediately surged forward, his huge dick slamming home quickly as the compulsion to fuck took over. Bigger and stronger than ever, he rammed his huge tool home hard, grunting bestially. He picked Ty up off the bed, holding him up off the ground, while they fucked, kissing his big-boobed lover eagerly, their massive chests mashed together--his made of pure muscle, Ty's made of womanly flesh.
