Keep railing Kara from behind.
From Create Your Own Story
You increase your pace, savagely thrusting into Kara while she continues to blow Matt. The sound of your balls slapping on her and the wet slurping sounds of your member pistoning in and out of her combine with her occassional moans. You reach a fever pitch and then explode inside of her tight cunt, blasting wave after wave of your seed into her. Her body shudders as she orgasms. You feel dizzy as your dick shrinks and you pull out of her with a plopping noise. She is so distracted that she pauses from blowing Matt. He grabs the sides of her head and starts to fuck her face, his hands buried deep in her long hair. He suddenly pulls his dick out of her mouth and she gasps for air as he jerks himself and shoots a load all over her face. She looks surprised and she sways unsteadily before curling up into a quivering ball on the couch and passing out, cum leaking from her pussy and all over her face and hair.
"Nice work bro!" Matt says as he initiates another high five. He is kind of a tool, you think.
"We should probably clean up a bit," you say as you put your dick away.
"Fuck that bro, I'm going to get my camera phone out and finish what she started!" he says indignantly, his limp dick hanging out while he strokes it casually and leers at Kara's sleeping form on the couch. "I agreed that I would let you hit it first, but I'm definitely hittin it." You remember why you didn't like him, he is an asshole, the kind of asshole that would fuck a chick while she is passed out and film it.
There are lines, and then there are lines. Will you let him cross this one?
