"Well, I want to give it a shot," Paul said, reaching for the bodywash.
Cathy didn't stop him, so he turned the shower back on and began lathering the pink foam all over himself.
"I think it's working," Cathy said before long.
Paul could feel his skin start to tingle. It too was starting to lose all its blemishes. Cathy started to run her hands over his arms. Paul shuddered. "Woah, my skin is so sensitive now. That feels really good!" he said.
He could feel his muscles starting to bulge under his skin. First his biceps under Cathy's wandering hands, and then his pecs. Paul couldn't tell, but Cathy noticed his shoulders broadening as well. She moved her hands onto his chest to feel his growing pecs.
"Aahhhhhhh…" he moaned. "Did it feel this good for you?" he asked.
"Sure did," Cathy replied, going in for a kiss.
Paul couldn't believe what was happening, even though he had kinda hoped something like this would happen. His body was turning into an adonis while becoming more sensitive at the same time. He was starting to feel really good and neither of them had even touched his dick yet. Though… as Cathy leaned in for her kiss, her body got close enough that his dick did kinda brush up against her leg…
Paul passionately returned the kiss, moaning as a jolt of pleasure shot through him as his dick brushed up against her. He could tell his body was still changing — muscles were bulging everywhere — but this was too intense. He had to have her now.
He started to feel her body, starting with her firm ass, working his way up her sides and around to her breasts. He massaged them briefly and twerked her large nipples. He briefly broke off the kiss to lick them as his hands found their way down to her vagina. Stimulating her clit he could already tell she was super wet, so he thrust into her, starting to make out again. He picked her up and pressed her against the shower wall, hands returning to massage her breasts.
Cathy was overwhelmed by all the sensations in her newly sensitive body. Just the brief nipple licking had nearly brought her to orgasm and when he touched her clit, she came. As he started to thrust inside her, she could tell that his transformation had finally reached his dick. It was already plenty big enough to satisfy her — especially with her increased sensitivity — but apparently the bodywash didn't think so. Cathy was already approaching another orgasm with his dick at its normal size, but as it grew, she didn't stand a chance.
Her body didn't even seem to want the change. She was already experiencing so much pleasure that she could feel her enhanced vagina fighting back against the increased girth of his growing member, but it was in vain. His dick kept growing in length and girth until it was well over a foot long, and increasing in sensitivity too.
Paul was overwhelmed by the new sensations. It seemed like his dick had already gotten far more sensitive before he stuck it in her, but now that it was growing, the sensitivity was increasing even more. He tried to slow down his thrusting to compensate, but between the extra squeezing of Cathy's vagina and its general pumping action, he couldn't hold off. He didn't want to go off since he could tell Cathy wasn't quite there yet, but he couldn't help himself. But as the wave of pleasure washed over him, he discovered that not only was he still hard, he didn't think he'd actually ejaculated.
And Paul still felt really good. Like he could go off again any second. He focused on pumping slowly, massaging Cathy's enormous perky breasts, and twerking her large nipples. Somehow managing to hold off another orgasm, he brought her to the brink and then sent a finger down to touch her clit. That did the trick. She let out a final moan, her body spasming, and Paul let the pleasure wash over him too. This time he could tell he shot a load deep inside her, and they both collapsed into the tub, exhausted from their lovemaking, utterly in bliss
