He’s fine with it

“OK, if we can pull this off that’s fine with me, I don’t see how, but what the hell. We’re down a pretty weird road.”

Grace looked at him and said, “Let’s fuck again.”

Jack was in agreement with that and moved over closer to her. "Here, move on my lap and turn your back to me. Put my cock inside you, and then you can tell me all your wicked thoughts while you slow fuck me and rub your clit.”

Grace moved up on top of him, his hard cock slipping inside her wet cunt with no problem. She moaned as she took his full hardness into her, and his hands went up to her tits as she slowly gyrated her hips on his cock.

“Fuck you fill me up. Do you think Joe will make me cum when he fucks me?”

“That’s kind of a fucked up question don’t you think?” Jack said back to her as he lowered his hand to her clit and slowly started to rub her erect nub.

Grace let out a loud moan, “Fuck yes, rub me just like that. Damn you get me so hot. Oh shit, it turns me on to think about you watching me be fucked by another man. I think his big cock in my pussy will make me orgasm. Fuck, I’m going to cum.” Then she groaned in pleasure as her body shook in orgasm. Her pussy got even wetter as she humped her hips on his cock, and Jack kept up a steady thrusting into her cunt.

“You like to watch don’t you? I know you got turned on last night when you watched me fuck Jennifer. Tell me what you were thinking about.”

“I don’t know, I just like to think about how your big cock looks slamming into her pussy, watching you fuck her was such a turn on. I know I shouldn’t have talked you into fucking her, but it was such a turn on. Now it’s all I can think about. Then you are going to watch another man fuck me. I’ll be thinking about your big cock fucking me when he mounts me. Fuck, I’m going to cum again.”

Grace moaned and reached orgasm again on his cock, her pussy so wet Jack could feel her lubrication and his cum mixed dripping from her pussy onto his ball sack. She was slick as hell with the cum load he had pumped into her and her own pussy juice and he focused on her hips grinding on his cock, he wet, tight pussy gripping his hardness as she fucked him.
