The Vacation

You decide to surprise your family by bringing your new wife to meet and get to know everyone on the annual family vacation. Your step-sister seems to really not be able to stand her. You see her constantly rolling her eyes whenever your wife talks, and glaring at her when she’s not looking. She pulls you aside to tell you that you shouldn’t have brought your wife here. She’s ruining the vacation. You try to reason with your step-sister and tell her it’s just going to take some getting used to, it’s not that bad. Your step-sister laughs, somewhat maniacally, and turns to you with an evil smile on her face. She stares at you intensely and leans in closer, she lowers her voice and says “Don’t make me ruin this vacation for you both, you know I could do it. It would be so easy. Your step-sister knows you better than anyone…” She leans her body in even closer before pushing you back into your chair. She drops her towel. She starts to grind her hips and tease you with her ass. She runs her hands up and down her curves while taunting you in a soft voice about your taboo desires. She knows you can't resist your step-sister, she could destroy your marriage in a heartbeat. She leans down to the camera, putting her chest right in your face. She pulls her bikini off of her tits, and reaches down to grab your cock through your swim trunks. She starts to stroke your cock until you cum all over her chest. She covers herself back up with her bikini, some of your cum still clearly visible on her chest. She tells you to clean yourself up, and says.. “This vacation is about to be MUCH more interesting, I’ll be making sure of that.”
