An ex-wife gal who used to live in Tokyo, after going through a divorce, returns to the countryside and has unprotected sex multiple times with her non-blood-related younger brother. Sarina, with a big sister aura, has H-level super beautiful breasts. The younger brother, who was a shut-in virgin, can't stop his excitement, passionately kissing and vigorously thrusting, resulting in multiple instances of internal ejaculation.
