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 she wants a period party 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 agrees to hang out and have some cake, which is an excellent 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.
