Chihiro always wanted to go to college in Tokyo and has finally made the move from his small town. However, a little problem of his has followed him to the big city: he's too sensitive, and a quick-draw in the bedroom. With that in the way, the college life he envisioned is nothing but a pipe dream. Chihiro opens up to his neighbor Kota, to which his new friend responds, "If you just get used to feeling good, you won't be as sensitive to it, right?" Before Chihiro knows what's happening, Kota kisses him and begins "sensitivity training" straight away! Sure, Kota is a more experienced and knowledgeable city boy, but does this normally happen between two guys!? Between a hook like "You wanna be able to do it with a girl, right?" and Kota's training methods, Chihiro can't resist! Sparks begin to fly between a sexy city boy and a straight country bumpkin! 都会に憧れ、大学進学を機に地方から上京してきた柊千尋。新たな出会いへの期待に胸を膨らませるが、一つ問題があった。それは【超敏感体質】のせいで、まともなセックスができないということ。リア充全開なアパートの隣人・逢坂虎太にそれを打ち明けると、『身体を気持ちいいことに慣らせば感度が下がるはず』という超理論で、Hな行為をすることを提案してきて！？戸惑う千尋だったが、経験豊富で押しの強い虎太についつい流され、あっという間にいただかれてしまい…？
