If Hiura get into the men's bath, Midou and Hiura would have gay sex covertly without any of their friends noticing. Midou would make sure to stretch that warm and wet bussy well.
Thanks for the translation.
Hiura would suck Midou's soul like a General Elecric GE90-115B high-bypass turbofan aircraft engine for Boeing 777-300ER. He would turn Midou into smithereens.
