The femdom mistress, her eyes glinting with sadistic pleasure, orders her bound sub to arch his back, presenting his tight, virgin ass for her pleasure. She selects a massive dildo from her collection, running it along his quivering flesh. She takes her time, lubing and stretching him, enjoying his whimpers. She slides the toy into his ass, inch by inch, until he's filled completely. She pounds him relentlessly, making him take every inch, her voice a cruel symphony of commands and taunts.
