Proposal turns on stepsister

Tiffany Watson and her stepbrother Alex D. have decided to play a prank on their parents, Lexi Foxy and Brad Newman. They collect fake wedding clothing and dress up, then go downstairs and announce to their parents that they've decided to tie the knot. When they aren't quite convincing enough, the stepsiblings lock arms around one another and make out to put on the best show they can. That's enough for Lexi to become upset, but Brad remains unmoved.The stepsiblings take it upstairs and admit to one another that they enjoyed making out. They keep it up in what they think is the privacy of their own room while Brad peeps from the doorway. Soon Tiffany is on her knees with Alex's cock in her mouth as she strokes him off while sucking the tip. Her deep throat BJ just gets them hotter and hornier, so Tiffany pushes her panties aside and climbs onto Alex's cock for a stiffie ride that is hard, fast, and oh so satisfying.Lexi joins Brad at the door as they watch their kids fuck. Brad succeeds in keeping Lexi from interrupting as Alex peels off Tiffany's thong and slams into her from behind. Their doggy style sex becomes more intimate when Tiffany rolls over so she can watch her stepbrother bang her as she explodes in a climax that milks a creampie of cum from Alex. That's the point where Lexi can't take it another moment! Exploding into the room, she confronts her daughter and stepson as cum drips from Tiffany's twat.
