LULU-405 - A 30-year-old unmarried woman living with her parents, unemployed, and with a large build, provocatively exposed her buttocks, frustrating her working younger brother, who then engaged in repeated sexual acts with her while attempting to counsel her. Tenma Yui.

Returning home after a long time, I found my older sister, with a large build, who had retired from working and become a recluse, still a NEET. I entered her room to try and reform my sister, who didn't even bother with part-time jobs and just played games in her room, only to find it overflowing with trash and anime merchandise. I became frustrated with my sister's defenseless large buttocks as she mindlessly played games to escape reality. Attempting immediate sexual intervention for reformation, she immediately lost control of her bladder! Years after the last intercourse, my sister's libido, who was an onani maniac, was released and repeatedly climaxed! I repeatedly engaged in intercourse to make my sister return to society and reformed her!
