Seeking help for premature ejaculation, a man consults his brother's girlfriend Rima, who declares that he must practice sex and begins managing his release. Slender fingers test sensitivity while she smiles and orders him to endure regardless of pleasure. Hand, mouth, and pussy take turns, stopping the instant he nears climax. When he erupts too soon, Rima continues into forced repeated release, escalating through big-ass piston strokes and accidental creampies until astonishing technique empties his balls.
