My Friend's Sister Seemed Quiet and Big‑Breasted, So I Secretly Seduced Her and Fucked Her Non‑Stop — She Turned Out to Be an Erotic Woman Who Climaxes Endlessly | 北村海智

About this work

After work Kenji and the others often drink at their colleague Hiroshi's house. One night a drunk Kenji peeks at Hiroshi's sister, the plain-looking Kaichi, while she's bathing and discovers she has a huge, sexy body — he becomes aroused and wants to have sex. Kenji waits until Hiroshi is away and approaches Kaichi; she complies with everything and doesn't resist at all, so Kenji goes at it as much as he wants with the ultra-sensitive, erotic Kaichi, who keeps coming endlessly.
