"Well, c'mon, honey..." she whined, this bloated, vulgar tart he'd made of his once classy and athletic girlfriend. "...get that dick up an do yer business. You knows ah needs it, baby."
Her pale, milky blubber rippled with her movements, causing her tattoos to jiggle (a rose on the right breast, a hart with "Jonny's Bitch" on the left, a butterfly on one thunderous buttock, the legend "FUCK TOY" above her shaved vagina) and bowl of her pierced navel to sway. Her nipples, nose and lip were also pierced...doubtless also her clit.
As he pulled his pants off (aided by Karyn. She had no patience for his delays) he wondered why he'd done this to his friend. Most people would have wondered. But then, Jon thought it was all clear.
For one thing, Karyn had always gotten on his nerves with her "Smarter-than-thou" attitude. THIS Karyn, unlike the original, would knew her place. "Trailer Trash" Karyn would never give him anymore lip on that score.
Secondly, their friends always seemed to think that Karyn was too good for someone like Jon. Even Karyn seemed to think so. Now Karyn would realize just how lucky she'd been to get him. After all, what other choices did she have? He was clearly the best she'd ever be able to do.
But mostly...it was sex. Jon had always been a secret 'chubby chasser', and Karyn had never been willing to go 'all-the-way' with him..

Karyn wrapped her fat lips around his shaft and started to suck. Her chins and jowls wobbled as she did so. Soon he'd come, and she'd lower her bulk onto his shaft. Then...who knows? They had a whole night to exparament.
