Just go with it

You and Kelly stare at each other for a long time while your cock is still hard inside her. Neither of you has cum yet and you're pretty sure Kelly is enjoying the sex despite feeling guilty about cheating on her boyfriend.

"Do you want to stop?" you ask, hoping she says no. Kelly doesn't answer.

"Do you want to keep going?" you ask, switching the question around but she doesn't answer either. She's obviously has mixed feelings about what you and her are doing and if you had to guess what's on her mind, it's that she wants to be fucked but she doesn't want to say it out loud. "Okay, we can keep fucking, but I don't want to hear your boyfriend's name again, got it?" you say. Kelly nods this time, eager to continue fucking.

You're about to resume your hip movements when you pause. Kelly had moaned her boyfriend's name in the heat of the moment and you have a feeling she'll do it again because she's so used to moaning it. You couldn't imagine a worse way to kill your erection if she cums before you do, so you quickly decide on a way to avoid that scenario. "Get on your knees," you tell Kelly, pulling out of her.

It takes her a few seconds to understand what you mean, then she turns around and assumes the doggy position, presenting her ass to you and you promptly insert your cock back into her pussy. She's looking over her shoulder in anticipation as you enter her but you don't start fucking her right away. Instead, you look around until you see a guy around the same age as you and Kelly and you wave him over to you 2. "Hey dude!" you call out to him. The guy walks over and you see he's packing a decent sized cock at around 5 inches.

"What's up?" the guy says, checking out Kelly and giving you a thumbs up as he sees your cock buried in her pussy already.

"Her mouth's available," you say, pointing at Kelly. Kelly's eyes widen and she turns to look at at the newcomer then at his cock near her face now.

However, the guy isn't so quick to offer her his cock. "What's the catch?" he asks cautiously.

"No catch. She moaned her boyfriend's name while I was fucking her just now and it's kind of a turn off, you know? Just looking for someone to plug her mouth so it doesn't happen again," you say honestly.

"Oh," the guy says. Then, he guides his cock to Kelly's mouth and she opens up to let him pass his lips. "Happy to help! I'm Tom by the way," he says, offering you his hand.

You laugh as you shake it. "I'm John. That's Kelly. It's funny because her boyfriend's name is Tom too," you explain as you start humping Kelly from behind.

"Good! Then she's used to blowing Toms then!" the new Tom says and you 2 start fucking Kelly at both ends.

Kelly seemed hesitant about blowing the new guy at first, but as she keeps going, soon she's using her hand to massage his balls while she sucks on his cock and he just stands there enjoying the blowjob. While the 3 of you keep going, another random guy wanders over and waits beside Tom. He's stroking his 3 inch cock and seems to be waiting for his turn at Kelly's mouth. Of the 3 of you connected together, Kelly is the first to reach climax and you feel her body spasming and pussy gripping your cock like a clench fist. She almost chokes on the cock in her mouth as she cums and Tom has to pull his cock out so that she can breathe. Unfortunately for Kelly, she only has a chance for a quick breath before the lurker tilts her head onto his crotch and he feeds her his smaller cock. Kelly makes some sort of vocal protest that's muffled by the cock in her mouth but she sucks on it nonetheless while you continue to fuck her.

Not long after, you start to cum, which causes Kelly to stop sucking the lurker's cock and look over her shoulder at you with alarm in her eyes. You grin as you keep cumming inside her and she doesn't say a word, knowing that it's too late to stop you. When you're done, you pull your cock out to show her some cum dripping off the tip, just to confirm to her what she already knows.

"Hey dude," Tom says to you, "Did she get fucked up her ass yet? Mind if I cut in?"

"No!" Kelly exclaims before you can reply. "No anal!"

Tom chuckles. "What? Is that only for your boyfriend? Come on, babe, let me fuck you in the ass," he says.

"No! I don't even do that with To- with my Tom! Your cock won't fit!" she says.

"How about mine?" the lurker asks eagerly, somehow thinking his smaller cock is an advantage in this case.

"What?! No! Damn it! I'm leaving!!" Kelly yells and she climbs off the sofa and scurries away without saying another word to you. She moves surprisingly fast and she's disappeared into the sea of naked people before you can think about chasing after her.
