After the sports festival, the top-tier girls from class 3-A came to the classroom to have a party. They ate sweets and drank alcohol... even erotic conversations that they wouldn't normally have can be said because it's "now"! The liberated girls' feelings change to horny ones, and eventually they even become lesbians! A boy who was secretly watching that situation! Of course, he was discovered and captured by the girls! I thought I would be subjected to all sorts of abuse, but is the target my dick? The girls attack my lower body with sparkling eyes! And they take turns! When I realized it, everyone was completely naked and in a gangbang state! Is this perhaps something that can only be done with the high tension unique to sports festivals? Anyway, this is my first and last experience having sex with top-tier girls, so I'll fuck like I'm going to die! Until I pass out!
