"Oh fuck..." Kevin writhed as he felt her pussy around his dick. His hands clenched the bedspread with all his might. A deep grunt escaped him. "God damn..." He couldn't stop himself. It was just too good. His body reacted and he felt himself finish inside Alicia. "S-s-shit..." he stammered out the curse as he pulled out of her.
"W-what's wrong?!" Alicia shot up as Kevin rolled off of her. He was groaning in pain as he writhed on the bed next to her.
Kevin couldn't respond. His body was in too much pain. Every part of his body was beginning to stretch. Before he knew it his legs had pushed past the edge of the bed. His large feet only extended further up into the sky. Both growing well past their size 13 shoe to something more like 15 or 16. "Damn it..." he growled as twisted and turned in bed.
Alicia quickly stood up, grabbing the sheets for some kind of cover. Somehow Kevin was growing again. Whatever little room they could have shared was rapidly shrinking as Kevin's body covered more and more of the bed. She may not have known much about sex, but this sure didn't seem normal. Watching as Kevin's massive frame seemed to grow even bigger was insane. Mass was pumping into his body, forcing it to grow bigger and bigger.
However, instead of just fat, there was a significant amount of muscle adding on as well. The bloated overweight frame was gaining some kind of definition as Kevin's oversized arms gained some definition. It was the same with his rotund belly. It quickly tightened up into a firm muscular gut. Even the faint outline of abs seemed to cover the front of his body. And the heavy moobs tightened against his chest creating powerful looking pecs.
Kevin grabbed at anything for support. His big hands only seemed to double in size as his fingers grew thicker. Deep callouses seemed to form on the bottom of his hands as though he'd been through hell of hard work. However, on the opposite side, hair started to grow. Thick patches of deep red hair covered the back of his arms and ran up his forearms. It covered his stomach, chest and even his legs. Then a large wild beard erupted from his clean shaven face. The rounded features were squared off by the extra hair.
"God damn..." Kevin cursed as he felt the changes subside. He looked around and then down at his body again. "God damn..." The amount of powerful mass on his body was unbelievable. He looked bigger than the biggest linebacker on the team. No longer was he the trim lithe muscle of a quarter back, but instead the huge bulky frame of a linebacker. He stood up, almost cautious of the ceiling. It was so much closer than it had been. Then looked down at Alicia. "You're so small..." He observed. "Hopefully this isn't a bad change either..." He raised his massive arm and gave it a flex.
Alicia had been getting used to the idea of the bigger man, but now he'd grown even more. She didn't understand what was happening but nodded. "You still look great."
"Thanks babe," Kevin smirked down at her. His bright blond hair had turned to a muddy red that now covered most of his bulky body. "But what are we going to do? There's nothing here that fits me and I've got class in the morning..."
Looking around the room, it was true. Kevin had to have gained well over 100 pounds since their first escapades and whatever he had been wearing looked as though it would tear apart under his new body. "And then what about class and football?" she added. Both shrugged trying to figure out what to do next.
