In the event "Tentacle -1 Grand Prix," teams of female students from colleges across Japan compete by creating their own tentacles. This year's final match features New Nakano College Tentacle Club vs Omiya College Tentacle Club. Players take turns attacking and defending using their self-made tentacles, aiming to stimulate their opponents' bodies and elicit reactions through touch. Points are awarded based on various actions during play, such as moans or orgasms. If a player cries out "Iku!" (I come!), they receive three points; if they continue cumming for five seconds straight, they earn four points. The loser must endure intense pleasure as their sensitive body is teased and filled with copious amounts of semen, leading to nonstop orgasms. This competition showcases the hottest youthful passion and determination. Note that recording contents may vary depending on broadcast method.
