A game where you have to guess the answers while being completely restrained by a mysterious wall and getting hit by a cruel vibrator! The cute and pure schoolgirl Kurumi-chan takes on this challenge. As she tries her best to find the correct answers, the more she struggles, the deeper the vibrations penetrate her sensitive body... making it difficult for her to concentrate! She becomes so aroused that there seems to be no other escape but through orgasm, leaving her helpless against the pleasure. "It feels too good... I can't think straight anymore..." Even though she's covered in oil, which should make things easier, she still manages to squirt uncontrollably. In the end, the staff has no choice but to give her multiple loads of cum as punishment for losing control during the intense gameplay.
