In a bdsm dungeon, a dominant woman, her face a mask of fierce concentration, straddles her submissive's face, her pussy lips meeting his willing mouth. She grinds, he gagges, as she commands, "Lick, slave." Her strap-on dildo, a thick, veined replica of her own sex, hangs tantalizingly close to his face, a promise of what's to come. Bonded wrists and ankles stretch taut, as she dominates every breath, every lick, every moan.
