Kokoro is a serious class representative at school. One day, a friend invited her to start a P-activity club on a whim. She was supposed to just have tea, but the man she'd met for the first time invited her to his house, and she couldn't refuse, so they became an adult relationship. Although she was confused, Kokoro was made to cum many times by the man's huge cock, and before she knew it, she was hooked on "old man sex" and fell into the swamp. Play in uniform, titty fuck, deep blowjob, continuous toy orgasms, creampie sex... a total of 6 ejaculations. Kokoro Ayase, who has a magnificent waist and big breasts reminiscent of a figurine, is "addicted to old men" and cums non-stop for 140 minutes.
