Miranda

"Miranda. I think that Matt is a little put out that I've gone away. He looks a little lonely over there." She looks over at you. "Since you're the only girl who isn't dressed solely in a guy's shirt, I dare you to take John's shirt, and head into the bedroom. Come back wearing only that shirt, and seat yourself on poor Matt's lap for as long as I'm on Tom's."
You curse internally. That is not what you had planned. But, Miranda is smiling at you as she comes over to you. "Can I have your shirt please?"
"Um... I think she said you have to take it." You raise your arms, and Miranda's smile gets wider. As she leans in towards you to grab the hem of your shirt, she whispers in your ear. "That was really nice, what you did for Nicole earlier. I always pegged you for a sweetheart." She pulls your shirt off, and you feel a little self conscious. You aren't cut like Tom or lean and lanky like Matt, just average. Not fat, but just average. Miranda doesn't seem to mind though. "Thanks. I'll be back." she brings the shirt to her nose, and is pleasantly surprise. "Ooh, I like your body wash. At least it's not Axe or some douchey shit like that."
Miranda retreats to the bedroom. Sarah seems to be enjoying her position on Tom's lap, and it seems that for Tom, one bitch is as good as another. He seems to think ever girl in the world should ride his dick, and he's not too picky. His hands freely snake up the front of her shirt, no doubt getting a good feel of her big tits. Matt is sullen, but trying to play it cool, though he still has daggers for you. You try to give him an apologetic look.
When Miranda returns in nothing but your shirt, your jaw drops. You and Miranda are pretty close in build, and your shirt isn't very big on her. Where Nicole and Sarah have some pretensions towards modesty, Miranda has no such luck. Your shirt stops at her waist, and despite trying to pull it down, there's no denying the show that Miranda is putting on as she returns to plop down on Matt's lap. She crosses her legs to give herself some cover, and gives you a smile. "Couldn't have worn a bigger shirt today, John?"
"Hey...I didn't know..." Her tits are straining against the fabric of the shirt you were just wearing. She looks so delicious in it, and you can't help but imagine waking up with her, fresh after a night of sex, with her wearing your shirt, just like that. From the spots of color in her cheek, maybe she's thinking similar thoughts.
"Nicole dear, would you bring me the ha-at!" Miranda jumps as Matt's hands reach around her waist, rubbing her exposed legs.
"Yeah, I gu-eess! uh, it seems to be an unwritten rule that if you're on a boys lap, he's just going to manhandle yo---ou!" Sarah shrugs as Tom shamelessly gooses her. I'm not opposed." Matt is looking directly at you, smugly satisfied. It's as if he's saying "Take away my girl, I'll just grope yours."
After a second, Miranda shrugs. "I guess. The hat please?"
