Two busty college girls on a hot spring trip are ambushed with a proposition: "Can you wash our male bathers' penises with just one towel?" They are challenged to an extreme mission with a high reward, involving extracting semen from bathing men. The sudden appearance of the two busty girls in just one towel surprises and causes the male bathers to become aroused. Despite their embarrassment, the college girls suck and stroke the multiple fully erect penises, extracting semen. Their arousal intensifies, leading to messy, frenzied, and ultimately, chaotic sex.
