A couple with twisted fetishes forces a cuckolding scenario. They barge into an AV studio, begging for anyone to insert their cock into the girlfriend's pussy... Ryosuke (32) and Misao (30). The shy girlfriend, unable to answer dirty questions, moans and turns away from her boyfriend as her nipples are played with. At her boyfriend's request, her pussy is licked, making her long legs tremble, followed by continuous spasms and orgasms from fingering and a wand massager. A kiss happens out of the boyfriend's sight, and after one last confirmation from him, the cock is inserted. Pounded from behind, she screams "amazing, amazing," moaning loudly in pleasure. She locks herself in the bathroom, letting out loud screams of climax through the frosted glass, then moves to the upper floor to writhe in ecstasy in cowgirl and seated positions. Feeling her boyfriend's gaze, she continues to moan in a panic.
