Tuning Club presents its longest and most ambitious project to date! Momoko challenges herself in an intense 9-hour marathon, fulfilling her desire to be thoroughly used by multiple men. In this incredibly lavish production, she engages in one-on-one sessions with nine different men, each lasting one hour. The seventh man delivers an especially brutal session, relentlessly assaulting her anus in an extremely hardcore manner. Even as she shows pain and attempts resistance, Momoko is pushed beyond her limits, continuously used to satisfy each man's desires without reprieve. This is the true experience of "being used." No matter how much she despises it or tries to reject it, there is no escape.
