Let Kara blow you until you come.
From Create Your Own Story
Kara's head bobbing up and down on your cock as her hands rub it is one of the best things you have seen or felt in your life. Although she isn't very good at it, her effort and the fact that this is happening at all is more than you can bear. You groan and buck your hips uncontrollably as you come into her mouth. She freezes and attempts to handle the situation by swallowing, which is helped by the fact that your dick is pretty far into her mouth at the point of explosion. You see her throat gulping and she keeps you in her mouth as your dick continues to pulse. She's pretty much defenseless, completely unable to move away, as Matt pulls her panties down to her knees from behind. He reaches a hand under her and starts to rub her mound and she gasps as she releases your dick from your mouth and shudders. You sigh as your dick flops to the side, still glistening with wetness from her mouth.
She turns her body and sees Matt's dick in his hand. He smiles at her and asks "My turn?". She laughs and spins around, crawling over in his direction. She grabs his beer from the floor and takes a big chug, almost falling off the couch... she is obviously intoxicated.
"I'm not a slut you know..." she says.
"Oh I know, this will stay between us, don't worry..." Matt reassures her as he gropes a tit playfully. She turns to look at you and you smile at her.
She smiles brilliantly back, and then turns to Matt again, smacking his hand away as she unconvincingly protests, "Okay, but no more touching Matt!" She leans over his lap and starts to suck him off. His eyes close and his head leans back against the couch, his hands intertwined with her thick reddish hair as he helps guide her head up and down. Her sexy little ass sways in front of you. The sight of this quickly makes you hard again.
You already got your rocks off and it looks like Matt will as well. This doesn't have to go any further and really a blowjob isn't that huge of a deal if Adam ever finds out. You could put your pants back on and wrap this night up without being a total douche at your best friend's house... or you could escalate the situation.
