The rings tangle with the zipper, which closed on the dick, resulting in a painful dick-trap

Billy's humped and Rachel ground her pussy down hard, then froze she felt a large spongy object pop past her lips.

"What?" she began, then tried to jump, with the unfortunate side effect that the rings in her cunt yanked up Billy fly, trapping his cock and making him shriek.

"What the hell's going on?" his friends asked, moving closer as Billy grabbed Rachel's tiny waist and yanked her down.

"Let me go! You... you pervert!" she yelled.

"Fuck!" he yelled back. "Stop moving, you're stuck on my zipper!"

Billy's friends stared for a moment before falling back onto their chairs in laughter. Rachel and Billy stopped their struggles and glared in unison at the others.

"This isn't funny!" they yelled as one, sending the others to new heights of hilarity.

"Fuck, I think you cut open my dick with the zipper!" Billy complained, trying to sort out the situation by feel. Unfortunately for Rachel the best approach was through her legs.

"H... Hey!" she gasped as his fingers found her wet twat.

"Sorry, I'm trying to figure out what happened," he explained, moving his fingers around her inner thighs and along her pussy lips. Rachel bit back a moan at his touch, her already fire up body wanting more.

"Here, I'll poke around," offered the bigger of the two.

As he knelt in front of the entwined couple Rachel muttered, "It better not be your dick doing the poking," which earned her a smirk.

"Don't you dare touch my cock," Billy exclaimed, jerking back, eliciting a yelp from him and an involuntary moan from Rachel as it rubbed his dickhead inside of her.

"Geez man, you had no problem pumping that gal Christina while I took her butt. You felt every inch of me, and our balls."

"Suit up, man, just get this zipper off my dick!" Billy screeched, while the other two guys snickered.

"Hey I remember that, Carl, Christina was awesome. Tiny tits, though. Not like this chick's," said the third to the man between her legs. Rachel found herself blushing as they both examined her breasts, their nipples poking up like they were reaching for the stars.

"Hey," she protested weakly.

"Yeah Tyrone, her body wasn't as good either," Carl said, looking Rachel up and down. "too much fat on her and she wasn't in shape."

"Fat makes for good butts," Carl argued.

Tyrone shrugged, twiddling a finger between her legs and making her gasp. "True, but I think Rachel here has a great butt."

"Thanks," Rachel muttered, ever-polite.

"Can't see it. Can you see it, Billy?"

"Would you two shut up and fix this? I think her rings are stuck on my zipper, which is stuck on my dick."

Carl wiggled his fingers some more, examining first the rings in her clit and clithood, then finding the first pair in her labia. He rubbed hi finger slowly toward the second, finding those to be free of obstruction as well.

"Damn, you've got a lot of piercings, girl," he said admiringly, drawing his finger slowly back out, making Rachel wriggle with pleasure. Even Billy gasped, the combination of zipper and rings acting like a cock ring, enlarging his already big dickhead into a thick purple monster.

"Just... unzip it! I don't wanna end up like that guy in 'There's Something About Mary'."

"Damn that Cameron Diaz is a babe, isn't she?" Carl said to Tyrone.

"She was, but I've seen some pictures where she looks too musclebound, too much like a guy."

"Yeah, well..."

"Guys!" Billy yelled.

"You know, we might have to take you to the hospital to get this fixed," Tyrone commented, much to Rachel and Billy's mutual horror.
