Brad takes the bottom bunk. When he can't sleep that night, he asks if Kenzie is awake. Kenzie gives him all of a few seconds to stroke it before she asks if she can watch or even help. Brad stands his ground right until Kenzie pops her tits and butt out while asking if this will help him cum. She starts sucking him down in a BJ that Brad isn't all that interested in stopping. She suggests it might happen faster if he fucks her as she gets on her hands and knees. Brad doesn't even argue before he shoves his dick balls deep into that wet twat. When doggy doesn't do it, Kenzie hops onto Brad's fuck stick and rides him all the way inside her hairy snatch. The bunk beds make their acrobatics much easier! By now Brad is intent on getting his stepsis off one last time as she lays on her back. Kenzie gets wind that Brad is on the edge she wraps her arms and legs around him to hold him inside as he blows his load for a creampie.
