Ayami Mizuchi, a kind and caring senior student, and Yuma Kaburaya, an ordinary and quiet boy, live next door to each other in the same apartment building. The older Ayami often helps Yuma with his studies. However, the younger boy, who is around her age, seems to be interested in her large breasts and body while studying, even though he knows he shouldn't. Yuma visits Ayami's house to deliver a notebook and sees Ayami masturbating indecently with a dildo. "Huh...? Ah...huh...huh?" The senior, who is usually an honor student, panics. Yuma panics and tries to leave the room, thinking he saw something he shouldn't have, but Ayami stops him, still half-naked. "I'll do anything for you...just keep quiet about this..." Ayami said. However, Yuma somehow felt that Ayami was the one who wanted to do something naughty... There are many erotic scenes and the content is full of fun!
