JUFD-945 A defenseless big-breasted sister gets fucked by her super-obsessed younger brother. She thought she was trying to seduce her virgin brother, but... it turns out to be a complete reversal! - Rina Otomi

Fitch exclusive Rina Otomi's first drama work! - Rina, who works as an underwear model in Tokyo, was returning home to celebrate her younger brother's birthday. - In contrast to Rina's parents who were happy to see her return home, her younger brother Yuzuru had a dark personality and was busy playing games without even coming to greet her. - He drunkenly showed his underwear to his younger brother, who is not interested in girls, and half-jokingly said, ``You can touch me for a little bit...'', which awakened his younger brother's dormant sexual desire. - From that day forward, my unlucky younger brother begs me to have sex with him all the time!
