Damasareta no wa Boku no Hou

Umino Mitsuki suffers a complex of insensibility or frigidity due to that in the past he was abandoned by his first love which became a trauma for him, and he has been avoiding repeating the same story with his casual friends and with his current colleague and partner Kubota. "Because I like Kubota who is so cute and kind, I want to have sex with him, even I try to use my fingers to get over it, but I still can not feel comfortable although I tried it by all means", while he worried about that in a business trip the weather was bad, so I would have to spend the night in the same room with Kubota?
