When I returned home for the first time in a while, my older sister, who had retired from being a working adult and became a hikikomori, was still a NEET. I tried to reform my sister, who doesn't even have a part-time job and just plays games in her room, but when I entered the room, it was overflowing with garbage and anime goods. I couldn't help but get irritated by my dick at my defenseless big-assed sister who was playing games mindlessly to escape reality. When I tried to reform her with a quick fuck, her pussy, which I hadn't seen in years, immediately leaked! With dick insertion after more than 10 years, the sexual desire of my sister, who was a masturbation maniac, was released, and she cummed repeatedly! I made my sister repent by creampie pistoning many times so that she would return to society!
