In a cramped, dimly lit room, a tense brother and sister find themselves alone with a forbidden curiosity. The brother, with a menacing "dread" head tattoo, can't help but notice his sister's nervous glances at his crotch. As he sits there, his cock twitching under his jeans, she tries to distract herself, but her eyes keep wandering back. "What are you tryna do?" he growls, making her jump. She blushes, stammering about how she's never seen one like his before. He smirks, standing up and unbuttoning his jeans, "Well, here's your chance, little sis."
