In a dimly lit dungeon, a Femdom queen, resplendent in leather and lace, wields a monstrous strap-on, her eyes locked onto her bisexual sub's trembling ass. She traces the toy's head along his crack, taunting him with the promise of fullness. He whimpers, pleading for her to claim him, to shove that big cock deep inside. She chuckles, a sound like thunder, and begins to push, her hips rolling as she impales him, inch by agonizing inch, until he's stuffed full and begging for more.
