"Would you like to make a lesbian mission with a prize of 500,000 yen?" Invite a pair of high-tension Norinori girls to a party by cosplaying in Shibuya, the sanctuary of Halloween, and drinking alcohol! The best friends who are familiar with each other are ashamed to gradually shorten the distance and challenge the first lesbian play with drunken momentum! Soft lips that touch each other, fine skin ... I can't stand the appearance of two serious and honor students being drawn into the mysterious pleasure that they first experience, and immersing themselves in flirting!
