[Reducing Mosaic]SGKI-073 "Tentacle-1 Grand Prix 2025" A-san, an elite scholarship student who was recommended for entry based on his ability to calmly endure being immediately penetrated by a modified tentacle

A special scholarship student is closely followed as they knock on the doors of a prestigious school to win the 'Tentacle-1 Grand Prix,' where female students from all over Japan gather. (A points-based competition where you use your homemade modified tentacles to stimulate your opponent's body and see who can make them react the most) In everyday classroom scenes, tentacles are always ready for immediate penetration; during pre-tournament training camps to overcome weaknesses, sudden tentacle orgasms send you to heaven; and in the finals of Tentacle-1, you experience uncontrollable spasms and incontinence from tentacle techniques beyond your imagination. "I can endure! I won't lose!" Further increasing sensitivity by several times with a blast of semen!!
