Mark's turn

"My turn, my turn," Marks says eagerly and he takes Devin's place while Devin goes off to the side of the room. Tom hands him a condom and you can see Mark roll his eyes as he opens the packet and slips it on. Tom sees his expression too, but again he doesn't say anything. With Devin recovering from his recent orgasm and Mark getting ready, the only cock Kelly is in contact with right now is Tom's in her hand. He starts to pull her head onto it for his turn at her mouth, but he's interrupted by Mark who has other ideas.

Mark wraps his arms around Kelly's slim figure and he lifts her up and gets under her, flipping her on top of him. "Come on, sit on my cock," Mark says, helping Kelly ease onto his cock. She's compliant and doesn't protest, and in fact starts to move her hips. As they start fucking, Tom is left out of the action entirely with his erection in his own hand. Kelly is so focused on riding Mark that she doesn't notice that he's being neglected and her head is tilted away from her boyfriend. Maybe it's because she doesn't want to look at him which she rides his roommate's cock.

Tom gets off the bed and moves around to the other side where Kelly is facing, but she then looks down at Mark, maintaining eye contact with him as they grind on each other. After a while of standing around, Tom finally gives up and takes a seat in a chair nearby and watches. Meanwhile, it looks Devin's room is the master bedroom of the apartment and he goes into the bathroom and you can hear him peeing. He returns to the room after flushing and washing his hands and he stands next to the chair Tom is in.

"Man, wish I could fuck her up her ass," he says.

"She doesn't do that," Tom says curtly.

"Yeah, her ass is too tight. Can't squeeze it in. Tried," Devin says with a shrug.

Tom looks up and doesn't say a word. Just then, as Mark and Kelly are humping like rabbits on the bed, Mark suddenly puts his hands on Kelly's hips and stops her. He lifts her higher, just enough to get off his cock and he reaches down and slips the glistening condom off and chucks it aside.

"Woah! What are you doing?!? Tom says. He's about to get up but Devin puts a firm hand on his shoulder and sits him back down.

"It's cool dude, we do it raw all the time," Mark says, pulling Kelly back down.

"Kelly?!?" Tom exclaims. She obviously hears him but she ignores him and slides back down on Mark's cock and they resume fucking, this time faster and more vigorous than before. You almost laugh out loud while invisible as you think about her earlier **** with you because she has a boyfriend, and now you learn she's been being used by his 2 roommates all this time. It sounds like Tom isn't even aware of how often.

"All... the time?" Tom says to himself and Devin pats him on the shoulder.

"Yeah, all the time. Chill out man, you know how sweet it is to cum inside her," he says.

"Huh?" Tom utters, sounding confused.

"Don't be sly man, a few nights ago when I with into the kitchen to get a snack and Kels was already there in that pink nightie of hers and there was cumming dripping down her thighs. She was still so horny that she bent over the counter and let me add my load to yours dude."

"That..." Tom says, looking stunned, "... wasn't..."

"Oh shit, must have been Mark then," Devin says with a chuckle. They then fall silent as they watch Kelly and Mark fuck, their breaths getting gradually faster and more excited.

"I'm cumming..." Mark groans.

"Me too..." Kelly responds and almost at the same time, they moan and grind their hips together and they cum at the same time. As if that wasn't enough, to add insult to injury, Kelly then leans down and kisses Mark tenderly for a few seconds before she breaks it off and then looks up abruptly at Tom and gasps, like she just remembered that she and Mark are not alone. She then hastily climbs off Mark's cock with some cum still dripping from it and her pussy.
