Laughter bounces off office walls. Balloons sway overhead. Ripped dude stands bare, muscles popping, cock gripped tight by blonde in glasses. She pumps slow at first. Others crowd in — dark-haired chick with heavy tits reaches over desk, fingers wrapping shaft. Black beauty in pink top leans forward, hand joining the stroke. Glasses MILF smirks, wrist twisting. Party hats tip as they take turns jerking. Desk chair spins. Cake sits forgotten. Hands slide up down, veins bulging. He throbs under the group tug. Blondes whisper dirty. Tension builds fast. Office turns stroke session.
