Kota has long harbored intense feelings for Emi, his mother's best friend, since childhood. One day, he stumbles upon an AV actress named Reiko Sawamura online who looks exactly like Emi. When he gets his hands on her DVD, he realizes it's actually her. Upon confronting Reiko with the truth, she agrees to keep quiet—but only in exchange for explicit sexual favors. Filled with pent-up desire, Reiko becomes obsessed with Kota's young, sensitive cock, leading to repeated creampie sessions as she rides him again and again.
