Yumana-chan (D-cup) who plays guitar in the light music club, and Ichika-chan (E-cup) who handles the bass. The two who trust each other temporarily forget their friendship and have a battle to make each other squirt using brutal electric massagers! They were acting tough saying 'We wouldn't squirt or anything...' When the electric massager hits directly, an immature body convulses uncontrollably, beautiful legs shake so much that you can't stand. Panic sets in from the abnormal pleasure for the first time. But escaping is not allowed, and the room gets wet everywhere. Synchronized squirting orgasm while connected to a lover! The loser of the game is sent to further depths of pleasure hell with a raw sex punishment. A beautiful girl is made to experience the core-shaking ecstasy of deep thrusting by an old man's huge cock, sucking it in front of her best friend, and attempting paizuri for the first time with her quivering big tits!
