A ruined orgasm leaves the penis untouched at the instant of ejaculation, making the semen dribble out before release is complete. The still-aroused cock is then driven into repeated erections and ejaculations. Nonoka Sato cycles between stimulation, abandonment, and release, ruining every climax while riding him hard in piledriver cowgirl until his cock and balls reach their limit. Celebrating KMP's 20th anniversary.
