Summer Sounds: A gyaru, an otaku, and a secret after-school life. [v1.04] [Sin Gularity]

August 1, 2026F95

You are a high school student who loves anime, manga, music, and other otaku things.
You live on the 14th floor of a high-rise apartment building in the city.
one day, Shiroine Touka, the popular girl in your class, wants to come over to your house to read manga?!

Apparently, in exchange for letting me read manga, I can use her body as much as I want…
She’ll let me cum inside her breasts, thighs, ass, pussy… and even cum inside her as much as I want…!?

As you and Touka gradually become closer,
Playing cards together, sharing meals, chatting on the balcony, even sharing the bathroom and toilet…!?
Will you tell me secrets you can’t tell anyone else…?

An immersive 3D after-school simulation game
Please, by all means, spend a precious and fleeting, wonderful after-school time just with you and Touka.
