In the dimly lit living room, the stepsiblings share a secret glance, a spark igniting between them. She leans in, her breath hot on his ear, "I've been bad, stepbro. I want your cock in my mouth." Her words send a shiver down his spine as she unzips his pants, his hardening cock springing free. She takes him in her hands, stroking him gently before taking him into her warm, wet mouth. Her head bobs up and down, her tongue swirling around his tip, her hungry eyes never leaving his. She can feel him throb, knows he's close, and eagerly takes his cum, swallowing every last drop.
