Leather chair squeaks like a dying animal. She rides him slow at first, tits bouncing in her tight blouse, then slams down with a wet slap each time. His hands grip her hips hard enough to leave marks. Switches to reverse cowgirl — ass clapping against his thighs. Comes with a shuddering gasp, nails clawing his shoulders. Cum dripping down her thighs as she collapses forward, still twitching.
