An ex-wife gal from Tokyo, after going through a divorce, returns to the countryside and has repeated unprotected sex with her non-blood-related younger brother. Sarina, who is like an older sister figure with a manly spirit, has H-level super beautiful breasts when she takes off her clothes. The younger brother, who was originally a shut-in virgin, can't stop getting excited, passionately kissing and vigorously thrusting, repeatedly ejaculating inside her.
