Akazawa RED box set (18+ doujin)

In a remote village, three adventurers decide to go out on a journey that’ll change their lives. Leed, the leader of the group, hears of an abandoned castle outside the village in which you can find the “The Succ Shop” – a place where sleazy succubi gather. They believe they are safe and that their skills will give them protection, but these little explorers are about to find themselves in big trouble… The consequences and the pleasures of their actions will overwhelm them!
