面倒くさがりで恋愛にも関心のない漫画家・累の元へ、突然現れたのはガタイのいい強面ヤクザ。うっかり保証人になってしまった知人の、数百万の借金を返せと詰め寄られ――「返済、待ってやってもいいぜ。セックスさせてくれたらな」勢いにのまれ押し倒されるが……大丈夫かな、私処女なのに。見た目どおりの強引さで酷くされるかと思いきや、優しくじょじょに柔らかく慣らされ、初めての快感に戸惑うばかりで――。
A tough-looking yakuza suddenly appears in front of Sumire, a troublesome manga artist with no interest in romance. An acquaintance who had accidentally become a guarantor approaches him and demands that he pay back a debt worth several million yen.“I don’t mind waiting for the repayment.If you’ll let me have sex with you,” he is overwhelmed by the force and is pushed down… I guess it’s okay, even though I’m a virgin. I thought he was going to treat me badly because he was as forceful as he looked, but he gently and slowly got me used to it, and I was confused by the pleasure he had experienced for the first time.
