Having some fun of their own

In the heat of the moment, you had forgotten about the other three completely. Turning around, you see that Sarah is on her knees with Matt's dick in her mouth giving a sloppy blowjob. In the corner, Nicole is sitting with her legs apart and two fingers in her pussy, her blonde hair thrown back as she pleasures herself, all former shame now gone. A brief thought of disgust crosses your mind - she's like your sister, after all - but is quickly replaced by feelings of lust as you watch her masturbate, one hand grabbing her small but perky breast and the other plunging inside her snatch. Despite the huge load that you just dumped inside the love of your life, you feel yourself begin to stiffen again.

As it turns out, Matt is really loud. With the red haired beauty bobbing her mouth up and down on his cock, he didn't seem to realise that he was groaning at the top of his voice. Just as you turn to watch the action, you see Sarah slip her index finger inside his asshole - this seems to push him over the edge, and with an obscenity he unloads his sperm into Sarah's mouth. The sheer volume of it must have surprised her, because unable to hold it all in her mouth you see much of it slide back down his cock. At the same time, a squeal behind you tells you that Nicole has managed to make herself cum, her petite frame shaking with the orgasm.

The six of you sit or lie on the ground, exhausted. "Well," offers Matt, "now we've got that out of our system I don't suppose there's much point continuing? I mean, it can't get much more **** than that right?"

"Hmm, I don't know about that sweetie," Sarah purred. "I've certainly still got a lot left in me. Remind me, whose turn was it?"
