After a long time, I went back to my hometown and found that my sister, who had retired from society and become a hikikomori, was still a NEET. She didn't even do part-time jobs but played games all day in her room. When I tried to reform her by entering her room, it was overflowing with trash and anime merchandise. Escaping reality, I mindlessly played games with a defenseless big-assed girl, and my dick suddenly got hard. When I tried to reform myself with immediate penetration, her long-neglected pussy immediately leaked! Her repressed sexual desires were released with a squirting orgasm after 10 years of no dick insertion! I made my sister return to society by repeatedly pistoning inside her and reforming her!
