The thought of your sister's wet tits has laid dormant in your mind for a while- until you finally see her again at a family reunion and her oiled up body reminds you of all the nasty thoughts you've gotten off to before. She even points out how she used to tease you by wearing only a skimpy bikini, which she'd caught your staring at more times than she could count. And that one day where she stripped off her bikini top and you finally got a glimpse of her bare chest. She knows that memory has replayed itself in your head ever since it happened. And now that you're alone, and she's freshly wet from the pool, there's no better time to play out the rest of your fantasy. You're slowly teased with your sister's tiny bikini before she unties it, giving you access to her oily, round tits at last. She loves your obsession over them, so much that she wants to watch you touch yourself just like you would when you fantasized about her body before. Your hard cock aches every time the light gleams off your sister's wet tits, the irresistible shine is going to make you cum. She keeps playing with them, kneading them in her palms and telling you how much she loves watching her big brother's cock get hard in his hand. And the second she tells you to cum, your cock is draining all over her beautiful naked chest. She's left to clean up the sticky white mess before the rest of the family arrives. **INCLUDES: taboo fetish / brother sister roleplay / POV / body tease / oily / wet and messy / glasses / bikini / taboo dirty talking / small tits / oily tits / titty bouncing / JOI / jerk off instructions / cumshot onto tits / big cumshot
