FOCS-276 My unemployed step-sister has a complex about her big breasts and is a virgin. Despite her big breasts, she has a shy personality. I'll release her troubled heart with some titty fucking and creampie sex! Yuki Koiro

When I returned to my parents' house for the first time in a while, I heard that my step-sister, who was born from my parents' remarriage, had become a recluse, so I became worried and went to visit her. Apparently, Koiro had been teased about her big breasts, and that was the reason she had become a recluse... As I comforted her by telling her that I would do something like a brother would, her expression gradually changed... She seduced me with her big breasts, saying that it was okay since we were step-siblings, and I, being the no-good kind of person, succumbed to her charms.
