(THIS IS A CUSTOM SCRIPT!) Evelin Stone is the eldest of three step sisters, Taylor Pink and Jasper Reed her annoying younger extensions. She knows they're always getting into trouble, but when she catches them having sex in the pool, she offers them a deal (after watching and masturbating, of course): Include their older step-sister in their sexual escapades, or risk being outed via secuirty footage. The three girls soon embark on the most intense and taboo underwater threesome you've ever witness... Evelin Stone has had an exhausting summer with her two younger step-sisters. Always loud, always immature, always annoying her! Luckily today she had plenty of alone time to read poolside, but suddenly, their splashing and giggling can be heard even through headphones. Evelin didn't see Jasper or Taylor come out from the house, yet somehow they're already in the pool -- and of course, being annoying! She stands, trying to make out what the pair are up to from their blurry shapes under the water... Only to discover they are fucking like crazy, throwing caution to the wind, and clearly believing they're alone.  She's shocked, yet somehow... Intrigued. Evelin carefully dodges the security camera only she knows about and has access to, slipping under the water to get a better look. Before long, though, she's slipping her hands into her bikini and enjoying the show far more than expected. Soon enough, all three girls have orgasmed in their own respective ways. Taylor Pink and Jasper Reed make their way to their picnic after ensuring the coast is clear. Stripping each other fully nude and passionately beginning all over again... Until Evelin catches them red handed. The deal is simple: Include their older step-sister in their sexual escapades, or risk being outed via secuirty footage. Things get a nervous start on the picnic blanket, slowly exploring each girl and taking turns until all three orgasm. But Evelin isn't satisfied with a little poolside action. She wants in on the underwater fucking, and she wants it now... Beginning a long-winded, intensely passsionate, eyes-open underwater taboo threesome.
