It's family movie night, but even your step-dad being in the room doesn't stop you from getting a boner over your little step-sister's sexy body. It's hard enough to pay attention to the movie knowing your step-sister's big tits are popping out of her bra, and now your dick is uncomfortably straining against your pants! Taking your dick out seems like a discreet way to relieve one of your problems -- right?? Not when the blanket you're hiding your cock under is a knit blanket you're sharing with your step-sis. It doesn't take long for her to notice the tented blanket, and see your cock head almost poking through the knitting! She tries to ignore you, but now that her step-brother's cock is so close and he's clearly very desperate for relief, her instincts to be a good little step-sister take over and she gives you a "helping hand" that turns into a "helping mouth" when she finds herself enjoying you just as much as you enjoy her. However your step-dad is in the chair right by you and at any moment he could turn around and catch his step-daughter blowing his step-son! It's essential for you two to be quiet, you stifle your moans and your step-sister whispers to you as she sucks you off. Can you feed your step-sis cum without step-dad hearing? It's the ultimate taboo challenge! ♥︎ ♡FEATURES♡ big step-brother x little step-sister, taboo roleplay, family fantasy, POV bj, cum in mouth, whispering, dirty talk, ASMR
