I'm lost in my own world, jerking off to fantasies of my stepsister, Melany Palmas, when she suddenly appears in the doorway. I quickly try to hide my erection, but she's seen enough. "Let me help you with that," she says, her voice laced with desire. She crosses the room, her hips swaying, and takes my cock in her hand, guiding it to her waiting mouth. She sucks me deep, her tongue swirling around my sensitive tip, her other hand massaging my balls. I can't help but groan, my body tensing as I prepare to release my load into her hungry mouth.
