As a college student, I decided to go back to the countryside for a week during summer vacation. There, I met Mai, a slightly older girl who lives in the neighborhood, for the first time in a while. She used to play with me a lot, but now she's all grown up, and when I see her tanned skin peeking out from her tank top, I get a kick out of it. Mai-chan, perhaps noticing his gaze, begins to show off her cleavage and seduce her. I couldn't resist the sensation of her flesh, so I started massaging her breasts.
