Bored one evening, I find my step sister in the living room, her eyes wandering to my crotch. She licks her lips, a mischievous glint in her eyes. "I've been thinking about you," she admits, inching closer. She unzips my jeans, her hand snaking inside to grip my growing erection. I tense, but she's already pulled me out, her tongue flicking against my sensitive head. She takes her time, exploring every inch with her mouth, her hands cupping my balls. I can't help but moan as she deepthroats me, her eyes locked onto mine.
