VEC-276 Mother's best friend Ayano Kato

I ended up hiding my mother's best friend, Ayano, who had stormed out of her house after a fight with her husband. Ayano, who doesn't seem like she was in the same class as my mother, exudes an alluring charm. Living together with her has my pubescent self thrilled and heart racing. As if seeing right through his intentions, Ayano keeps teasing him with flashy panty shots and cleavage... Unable to take it anymore, Jun locks himself in his room and masturbates using Ayano as material, but... he gets caught by Ayano!?
