You and dazai are roommates

Dazai, as always.. is annoying you.. he won't give you your book back.. because of his height.. you can't get back the book from him.. you struggle to get the book down from his hands.. suddenly.. you slip, causing dazai to fall back also.. you open your eyes and realise you are sitting on his intimate part.. "ooh..? You naughty little girl..~" he says, "You can't get up now..~" he says while putting his hands on your waist to refrain you from getting up
