Feeling the front of the diaper begin to soak through, Rebecca smiles and grabs a fresh diaper. She slides it onto Joe, right over the first one, in one fluid motion that didn't interrupt the mood. She even bent down and kissed the front of it too.
It was then that things started getting even more unexpected. Starting with Shannon pulling out Rebecca's bra from her bag, and putting it on Joe. Joe of course was a bit confused, but asking would ruin the good mood they currently had going on so he silently wished that whatever kind of fantasy these girls had thought up would actually happen, but would only last for 24 hours max.
As if on queue, his chest began to fill out the bra until it was literally straining to stay clasped. His new boobs were easily the largest pair of the 5 of them here. His hair lengthened down to about ass length and turned raven black. At the same time the rest of his body hair vanished, leaving behind flawlessly fair and smooth skin. His double layered diaper began to feel tight as his ass ballooned outwards into a perfect bubble butt. He could feel his balls shrink until they either vanished or slipped back inside of him, however his cock only grew larger, only for a new, empty feeling, dampness to appear right below its base where his balls used to be.
"Sorry about this Joy, but if you wanna come with us, then you at least need to cover up that pipe sticking up from your pussy" commented Justine. It was then Shannon who spoke up next. "But don't worry, we all know you are not to blame for having such a massive clitoris. Honestly I think it is kind of hot knowing one of my friends has a clit bigger than most guy's cocks."
"I agree, but you and me seriously need to go out shopping. I'm sorry to say this Joy, but as much as I charrish being big boobie sisters with you, I can't keep trading bras with you anymore. You now are a full cup size bigger than me, at least" added Rebecca.
It was Joe's, or Joy's turn to speak now. "Then maybe after the beach we can swing by the mall?" She says, loving how her new voice sounds. "Sounds like fun. But only if you buy me dinner first." grinned Rebecca. "Then its a date." agreed Joy.
"Alright you lovebirds, are we going swimming or are you two just going to flirt all day?" Commented Candace, who already was wet up to her knees from wading into the water.
