Cathy hadn't been dating Paul long, but they had sex on their second date, and he was probably the best lover she had in terms of both size and skill, and he also always seemed pretty ready to go ...
It didn't completely surprise her when he slipped into the bathroom, naked except for boxers he was sliding off, announcing: "Hey, it's me! Coming to join you, babe!"
Cathy realized she had left the shower on, she was so distracted by her transformation.
She saw Paul enter, stroking his dick, already half hard, and start to head to the shower before he noticed she was standing outside of it. The room was full of steam at this point, semi-obscuring his view.
"Whoa," he said, wrapping his arm around her neck and shoulders, and the other around her waist, as he pressed his forehead against hers: "Someone is looking exceptionally hot today. You even smell particularly ... sexy. "
Cathy started to speak, but she couldn't seem to concentrate. She had just masturbated to at least three or four orgasms, but she could feel his erection poking her, and growing harder. It felt like her heart was beating in her pussy.
"Do you want to ...?" Paul asked.
She could only breathily sigh affirmatively.
She felt him pulling her into the walk in shower. She heard herself moaning as he sucked her giant nipples. Then he began to feel at her crotch.
"Fuck, you've never been so wet!" he observed, then Paul was inside her a second later, lifting her against the shower wall.
Her eyes closed tight as she felt her enhanced pussy taking over for both of them, just like she imagined it would, with a cock inside, clenching and stroking and manipulating his penis.
He began by thrusting into her, but soon, even though Paul was still holding her up by her supple ass, supported against the shower wall, she was really fucking him, he was letting her pumping pussy do all the work.
Her pussy edged him to orgasm several times before instinctively backing off, and rising repeating the cycle, driving both of them to a higher climax when it finally happened. After a good 10 minutes, Cathy couldn't take it anymore and began shuddering all over, her back arching, and her pussy going into overdrive to get Paul to finish. Paul began to moan like she had never heard him do before as he approached ejaculation, and he let out a great roar as he shot his load inside her. Cathy nearly blacked out again as her body somehow sent an even more potent wave of pleasure through her body as her vagina absorbed his cum, preventing her from getting pregnant.
Paul also seemed near the edge of consciousness from their lovemaking session. But he soon recovered and now that the steam had disappeared, he was finally certain that something was very different about his girlfriend.
"You look different." he said. "And that was way more intense than normal. What's going on?"
Cathy explained about the bodywash and what had happened. Paul seemed a bit skeptical, but given the evidence before his eyes, it seemed he had no choice but to believe her outlandish tale.
"Can I try it?" he asked.
"I don't know…" Cathy mused. "The lady in the shop didn't say anything about other people using it…"
