I'm going to the city to continue my studies, so I'm staying with my cousin, "Big Sister Hikaru," who used to look after me when I was little, for a week to prepare for my move. Ever since I was little, my big sister was kind and taught me many things. But now that I've grown up, when my big sister is nearby or I get a glimpse of her breasts, I can't take my eyes off her and my body gets hot... "Do you remember? When we were little, I used to do this in the bath." "Big sister will be the one to give you your first experience." Behind that kind face is a perverted big sister who enjoys little boy dicks.
