Shiritarou ~Butt-Guided Strange Journey~

"I'm not a young lady. I'm a boy..." A young man who's afraid of someone stalking him, Shiritaro, visits the "Inui's Detective Agency", which is described as a " seemingly clumsy and unreliable place, but is actually a reliable detective agency." For some reason, Inui is reluctant to accept the cry for help, but when he bites into the dumplings Shiritaro brought him as a gift, an animalistic desire wells up from the depths of his gut, his crotch grows larger -- and Shiritaro approaches him... A strange journey with a beautiful boy and three other men, START!​
