SONE-793 _The sister who works online wears revealing clothes

Because my parents are on a business trip, I currently live with my older sister Ashitaba. Every day when we work and study, we two sisters live together in the same room. An important exam is coming up, so I'm determined to study hard to get into my dream school. But the fire of determination gradually extinguished because of my older sister. Every day when she works online, she only wears her upper body and... no pants. Her round butt teases me every day. I was still a virgin and didn't know the taste of girls, so I couldn't help but rush in and hug Ashitaba even though she was in a meeting with the director. Understanding the feelings of his beloved younger brother, Ashitaba taught me the basic steps to please a girl. She is truly amazing, right guys?
