NTR Dungeon

One day, a parcel brought by "Sakura" of childhood friend to the main character.
When I opened it, it had been flown to a different world created by Succubus!

While there are many men and women other than the main characters, Succubus appears and tells them that he must capture the dungeon in order to escape.
He also said that all the women who were involved had "inamon" engraved on them.

If you do not escape early, the "Inmon" carved into the woman will run away and seek sexual activity, the curse that will become succubus sooner or later……

The main character aims to escape in order not to succubus Sakura!

ある日、主人公の元に幼馴染の『サクラ』が持ち込んだ小包。
それを開くとサキュバスの作り出した異世界に飛ばされていた！

主人公達以外の男女も大勢いる中、サキュバスが現れ脱出するためにはダンジョンを攻略しなければならないと告げる。
そして巻き込まれた女性全員に『淫紋』を刻み込んだとも言い出した。

早く脱出しなければ女性に刻まれた『淫紋』は暴走し性行為を求め、いずれサキュバスになってしまうという呪い……

主人公はサクラをサキュバスにさせないために脱出を目指す！
