A busty tomboy sister with a sharp pixie cut takes her younger brother hostage for an intense "practice session," teasing him about premature ejaculation before pushing for more, squeezing her heavy breasts around him and demanding he pleasure her. As she straddles and rides him, her growing frustration builds toward climax, only for him to tap out in a panic, leaving her to declare she's far from satisfied and hinting she'll wring another round out of him.
