Kelly, confident and dominant, commands Mark to bend over the bed. She admires his naked, exposed body, running her hands over his muscular back and ass. Her girlfriend's touch sends shivers down Mark's spine, his cock hard and ready. Kelly brings the dildo to his ass, rubbing it gently, making him squirm. With a wicked grin, she pushes the toy inside him, inch by inch, until it's fully sheathed. Mark moans, a mix of pain and pleasure, as Kelly starts to peg him, her hips thrusting rhythmically against his ass.
