Kyle Mason and his stepsister Blair Williams are studying at their teacher Cherie Deville’s place, but Kyle can’t keep his eyes off his bombshell of a teacher. When Blair catches Kyle staring down Cherie’s shirt, she calls her stepbrother out. Kyle can’t understand the problem since he’s already fucked Cherie, but it’s only after he’s opened his mouth that he remembers that’s supposed to be a secret! Cherie runs to her room and Blair follows a moment later to comfort her teacher.When she has Blair alone, Cherie sees her opportunity to let it slip that she’s not just into guys. Blair seems open to her touch as Cherie offers to give Blair her first girl-on-girl kiss. She is soon putty in Cherie’s hands, especially once Cherie starts peeling off Blair’s clothes and reaches down to finger her clit. Kyle walks in on them just as things are getting hot, and it turns out that both girls are open to inviting him into their sexual romp for a threesome.After they take turns deep throating Kyle’s cock, the girls arrange themselves so Blair has Kyle’s hardon buried between her thighs and Cherie’s pussy planted over her face. They switch things up so Blair is on her hands and knees enjoying a pussy pounding, but then it’s all about Cherie’s pleasure as she takes her student’s big dick deep inside. Cherie gets a doggy style fuck of her own as she feasts on Blair’s snatch until both girls have enjoyed all the climaxes they can handle. Then they get on their bellies and work together to stroke Kyle off until he delivers a double facial with cum that drips into their open mouths.
