Living his days working seriously as staff at a university, Maki hasn't seen love in a long time due to the trauma of being dumped for his huge dick. One day he helps out new student Kouta, who he sees being harassed by members of the travel club (infamous for being a sex club), but for some reason Kouta seems odd......?? Actually Kouta, having reached sexual maturity late only a few months ago, has been uncontrollably horny and suffering from symptoms of desperately wanting to have sex with someone. Although he dismisses Kouta's request to have sex at the workplace, Maki's body reacts from being groped, and Kouta finds out about his huge dick...!

What will happen to the sex-friends relationship between Kouta, who makes horny expressions from wanting to do sexual things, and Maki, who has a complex about his dick size!?
