Shinjin Hatachi no Onee-chan AV Debut!! Yuuki Rin 2 - Ore no Nee-chan wa Geki Iki Kyonyuu no AV Joyuu

Yuuki Rin is a brilliant student attending a prestigious private university. If you ignore the fact that she’s an AV actress, she’s just your average college girl. Even to me, her younger brother, she’s beautiful, kind, and someone I’m proud to call my sister. But one day, she dropped a bombshell. “I’m dating our cousin, Micchan, with marriage in mind. So, don’t you dare tell him I’m doing AV, okay?”
