VEC-598 Teenage boy secretly flirting with his mother's best friend

A vacation with nothing to do. Hiroki, who was about to spend the whole day wandering around, appeared in front of his mother's best friend, Miki. Hiroki fell in love at first sight after being captivated by her beauty. Not to mention her sex appeal, I couldn't even make eye contact because I was so distracted by her massive breasts that were about to pierce my clothes. Hiroki looked at the person bathing with longing. However, instead of being scolded, he was given good guidance.
