A late-night call from an unknown number turns out to be an adult former high-school classmate who missed the last train after a party. He lets her stay for one night and discovers she has grown into an aggressively horny gyaru. She gives him an unwashed-cock blowjob at the door, presses against him in the bath, and reduces him to jelly with expert handjobs. Drowning in pleasure, the two fuck and creampie repeatedly until the sun is already up.
