Back to the plan

When she pulled away from the kiss, she looked momentarily over at my unconscious brother and frowned.

"I guess I should have fucked him," she said. "I just got excited about both of my boys cumming on me at once. I've never ruffied a guy before, I don't know if he can get it up again or not."

She had a point. The whole reason we were doing this was to convince him he'd gotten drunk and knocked his wife up. Getting a blowjob wasn't going to do it. He needed to legitimately think that they'd had sex.

"Okay, what so we do?" she asked. He dripping pussy was still pressed hard against my cock.

"Well, you could try to get him hard again," I suggested. "Maybe suck him some more...and while your busy I could be behind you doing other things?"

"Or I could just make you cum all over his cock," she said.

"Not as much fun."

"For you maybe," she said, thrusting against my erection. "Or we could just go ahead and fuck and then I can sit in his lap and leak all over him."
