With a gleam in her eye and a wicked smile, the mistress presents her massive strap-on to her sub, who eagerly takes it into his mouth. She fucks his face, pushing in deep, making him gag and choke. Once he's warmed up, she bends him over, his ass on display, and lubes up her toy. The first thrust makes him gasp, his fingers clawing at the sheets as she slowly, relentlessly pushes in, filling him completely. She sets a brutal pace, her hips slamming against him, her hands gripping his hips hard enough to bruise. The sub's cries of pain and pleasure fill the room as she pounds his ass, her own pleasure mounting with each thrust.
