Anna Claire Clouds and her friends Katie Kush and Kyler Quinn are setting up for a period party. Oliver Flynn, Anna's stepbrother, is so confused about why Anna wants a period party now since she got her first period a long time ago. Anna points out that she didn't get one when her period started, so she wants to have one today. Oliver takes that opportunity to out Anna's family fantasy, which her friends very kindly ignore.Oliver agrees to hang out and have some cake, which is a really good idea since he gets to watch the girls bouncing around in their short red dresses as they try to hit a uterus pinata. When Oliver brings the cake over with his dick out like he's gonna fuck the frosting vagina, Katie and Kyler try to stop him, but Anna tells him that maybe he should. That's when she shares that the party isn't to celebrate her first period; it's to celebrate her last period for a while. When Oliver asks what his stepsister means, she puts it in plain English. She wants Oliver to fuck her and her friends.Without giving Oliver a chance to decline, the girls get onto their knees to share Oliver's cock in a triple BJ. Then they help Oliver to the couch where Anna climbs onto his fuck stick and rides him in reverse cowgirl as Katie and Kyler support her. Katie gets the on her hands and knees next so that Oliver can satisfy her juicy snatch in doggy while also eating Anna's pussy. When Oliver sits up, Kyler impales herself on his dick to ride him. Adjusting their positions, Anna manages to ride Oliver's mouth while Kyler eats Katie out. The foursome forms a pussy pleasing chain as Oliver bangs Anna on her back, with Katie riding her face and leaning forward to eat Kyler's fuck hole. As Oliver makes it known that he's getting ready to nut, the girls make sure that he blows his load in a creampie inside his stepsister to hopefully impregnate her.
