Please a woman's ass

Her friend had vouched for Curt, said he knew exactly how to please a woman's ass. Lorelei wants the proof herself. She gets him on his knees, wrists bound behind his back. A thin rope loops under his balls and around his shaft, every tug a warning. She turns, spreads, and orders him close. His tongue works her rim with slow, steady circles until she grinds down harder, taking what she wants. Lorelei rocks her hips and the rope pulls tighter. His balls ache, his cock swells uselessly in the air, but his mouth never stops. Every time he slows she gives the cord a sharp jerk that makes him gasp against her skin. She holds him there until she's had her fill, then pulls away and leaves him throbbing on the floor, hard and bound, exactly the way she likes her toys.
