Rhythmic Muscle Encounter

Takumi Nodono is big and bulky, but contrary to his looks, he loves cute things. One day, an adorable guy, Itsuki Tenra, chats him up and seems really interested in his body. Itsuki mentions that he's been in various incidents on the train and wants to work out in order to get stronger. His slim body and plump behind light a fire in Takumi's imagination.
