A couple trying to enjoy their date fall into an unexpected trap. Unable to pay the fee, they are forced to comply with the demands of a perverted bar and dragged into a series of rubber mask games. The first mask is an extreme design allowing breathing only through the nose, making it increasingly difficult to breathe as they are tormented. The rubber mask tightly sealed over the mouth prevents sufficient oxygen intake, pushing them into a panic. Yet, this agony gradually transforms into unexpected pleasure. Next comes the rubber tongue mask, featuring an inverted protruding rubber tongue that contracts with each breath, simultaneously inducing discomfort and arousal. The boyfriend is restrained in a full-body suit and forced into intense rubber tongue blowjob play, surrendering helplessly to its overwhelming sensation. Finally, the blowjob face mask appears, forcing him into deep, relentless oral play with bright red lips turned inside out and thrust into his mouth. This entire series of acts, promoted under the slogan RUBBER RUBBER, becomes an extreme experience that shakes both body and mind.
