You're on vacation at the family beach house with your wife's family, which is great and all, but your wife hasn't been putting out. On top of that, her slutty younger sister has been walking around teasing you all week. She comes to let you know that everyone is going into the hot tub, and invites you to join. You don't even notice that you get a huge boner just from seeing her in her jean shorts and swim top, and thinking about her in the hot tub when you haven't had sex in so long.... she happens to glance down and notice your little ermmm BIG issue, and teases you about it. She says maybe you should go "take care of it" in the guest room before coming to join everyone outside. But that wouldn't be very fun now would it? She teases you again saying "if you can cum in under 10 minutes I'll help you out". Are you up to the challenge? ;) Includes: homewrecking, cheating, sister in law, dirty talk, bj, messy bj, sloppy, deepthroat, some wife degrading talk (very minimal), riding, and creampie
