VEC-598 The teenage boy is secretly involved with his mother's best friend.

A vacation with nothing to do. Hiroki, who was about to spend the whole day wandering around, unexpectedly appeared before his mother's best friend, Miki. Hiroki fell in love at first sight after being captivated by her enchanting beauty as she smiled. Not to mention her sexual appeal, I couldn't even make eye contact because I was too distracted by her huge breasts that seemed on the verge of bursting through my clothes. Hiroki gazed at the person bathing with longing. However, instead of being scolded, he was given attentive guidance.
