Andrew was thrusting hard into her each time. Every thrust in causing him to pull on her hair, pulling her back onto his cock as he thrust forward. Slap after slap rained down on her ass until he shifted tactics, sliding his hand around her hip to start rubbing at the edge of her slit, right against her clit. He leaned forward and nipped her back with his teeth, continuing his unrelenting assault on her body. "Oh yeah?" He continues. "I want you to cum on my hard cock before cum inside of you, you little slut." He hisses, spanking her ass once more.<br/><br/>His balls were slapping against her too now. Every thrust saw every inch of his member penetrate her, his hips pressing tight against her before he moves them back, barely giving her a moment to prepare herself for the next thrust. "I'm gonna fill you up real soon."<br/><br/>---<br/><br/>Peter nearly jumped when he felt hands on his cock and looked down, realizing that Abigail had rejoined him. He was enthralled by what he was watching through the door, but the words of his sister made the hairs on the back of his neck stand on end. Had she really just said that? She left with a squeeze of his balls and he bit his lower lip. Fuck it, he was intrigued. He stood up and followed after his sister, almost walking into her when she paused in the doorway. Was she really serious about this or was it a ploy to ruin his evening?
