Sister × ○○ ~ Absolute ○○, celebrity sisters and daily creampie sex life ~ limited edition

The main character, Naoki Shitara, is fired from the parking lot management job of the university where he worked, and has become semi-desperate.
The reason was because of Naoki's work attitude, but for him who has lived with a selfish personality until it was over 40, such a thing does not matter、
He was drunk with alcohol and was relieved of his worries.

One day, Naoki causes a dispute with other customers at a bar and is forced to leave the shop.
While returning home complaining, Naoki jumps out into the road with his legs tangled due to his drunkenness, and makes contact with the car he is heading for.
The woman who got out of the car calls somewhere with her mobile phone and Naoki faints while watching the figure.

When I regain consciousness, there are two women there.
Apparently these two people seem to be the perpetrators who ran over themselves.
Moreover, Naoki knows that the accident can not be put out on the table due to circumstances.

"What selfish guys ...... then I will act selfish against them, too!」

Naoki begins to act in order to use the two women.

主人公・設楽直樹は勤めていた大学の駐車場管理の仕事をクビになり、半ば自暴自棄になっていた。
理由は直樹の勤務態度が原因だったのだが、40過ぎまで自分本位な性格で生きてきた彼にとってはそんなことは関係なく、
周囲に当たり散らし酒に溺れて憂さ晴らしをしていた。

そんなある日、直樹は飲み屋で他の客と諍いを起こし店を退店させられる。
文句を言いながら帰宅している最中、直樹は酔いのせいもあり足がもつれて道路に飛び出し、向かってきた車と接触してしまう。
車から降りてきた女は自分の携帯で、どこかに電話しその姿を見ながら気絶する直樹。

意識を取り戻すとそこには二人の女が。
どうやらこの二人が自分を轢いた加害者らしい。
しかも事情があって表に事故のことは出せないことを知る直樹。

「なんて自分勝手な奴らだ……それなら俺もアイツ等に対して自分勝手に振舞ってやる！」

直樹は二人の女を利用するため、行動を開始するのであった。
