Close, but no double bj...

"Go!" Miranda yells with excitement. She seems quite keen on watching her oversexed housemate get fingered, leaning forward on Matt's lap. You can't help but stare in desire at her as her breasts strain against the fabric of your t-shirt. Nicole shifts on your lap, watching intently as Sarah gets fingered. She obviously has a vested interest in the outcome.
Tom's technique is aggressive, but a little crude. You can tell that Sarah is enjoying it, as she pulls her shirt up to expose her big tits and rub her nipples while he works. The spectacle is quite hot, and you can't help your own cock from getting quite stiff, which can't be lost on Nicole. She seems to have noticed, and begins slowly grinding her nethers against your bulge.
"mmm...." Nicole moans softly. "Thanks for that..." she looks back and gives you a dumb smile, and you try not look embarrassed. "Getting excited, huh?"
"Mmm...fuck..." Sarah begins to moan, and Nicole begins to grind against your bulge more quickly.
"I really don't want to suck Tom's... thing..." Nicole murmurs, giving little moans of her own as she dry humps you. Across the way Miranda seems to be using Matt in a similar fashion.
"Two minutes left..." Miranda calls out hoarsely. Sarah has a small smile on her face now, clearly lost in the pleasure. Tom's face is fixed in concentration as he works his fingers frantically in Sarah's cunt. He's whispering dirty things to her, but a little too quietly for you to really make them out.
"Thirty...ah....seconds..." Miranda looks like she might cum herself, and so does Matt. For that matter, your own cock is throbbing from the stimulation of Nicole's undulations.
"Oh...baby... that's... yeah that's the spot..." Sarah arches her back, giving Tom a better angle, and she starts to breathe heavily and give little moans. "Oh, baby...yeah...I'm close... are you going to make me sing, Tom. Like you promised?"
It comes down to the wire, and just when you think you might bust a nut right along with Sarah, Miranda raggedly calls out. "TIME!"
"FUCK!" Tom groans in frustration, and right on top of him, Sarah yells, "Fuck! I'm cumming...!!!" She begins to shiver and shake and buck her hips, and Tom finishes her off almost on autopilot, though he clearly knows he lost. Miranda gives a little performance of her own, and you believe that she has had an orgasm from dry humping Matt's dick. It's magical to watch, and you nearly cream your pants before Nicole stops humping herself on your bulge.
"Oh, thanks for the effort, Tom. You almost did it..." Sarah twists around to give him a sexy kiss before hopping off his lap to plop down on the couch next to Miranda and Matt. Tom is not happy about losing his lap lady, but he takes the hat from Sarah's outstretched hand to pull a name.
