Shelli's cruel smile widens as she surveys her bound prey, ready for her sadistic games. She clamps his nipples, twists them, and makes him beg for mercy. She trails a wet, warm tongue along his shaft, teasing his cock, then abruptly stops, leaving him aching. She spits on his dick, laughs, and tells him, "You'll only cum when I say so." She tortures him with pleasure, edging him close to climax, only to deny him. Finally, she fucks him hard, her pussy clenching around his cock as she screams in ecstasy, allowing him to follow suit.
