Kenji proposes Polynesian sex to hear the voice of his girlfriend, Maru, who is too shy to let her hear her voice.
His girlfriend, Mitsuru, always covers her mouth with a ball gag during sex because her “panting voice is weird and embarrassing.”
Her boyfriend, Kenji, had often asked her out when he didn’t have a ball gag in order to hear his voice, but he always refused.
One day, Kenji thinks that if he teases her, she might be okay with it, so he proposes Polynesian sex to Maru.
In order to hear Mitsuru’s moans, Kenji spends five days trying to make her cum!
