Promise and Contract Sanctuary-Even if Cuckold- v.1.1 / 約束と契約のサンクチュアリ～たとえ寝取られたとしても～

Kuru, the royal sword warrior, is ordered by the king to explore the Seiko forest, which is said to contain the altar of the god Kuseshiri.
In the middle of the investigation, he meets Umi's girlfriend, who is an ordinary person.
To help Kuru, who was injured during the investigation, Umi takes Kuru to the village where the residents of Kuseshi live.
In this village, Kuru finds what is really important to him, living with Umi.

The story consists of two parts: the first and the second. The first part is mainly a scenario for deepening the relationship with the heroine, but since
the volume is a bit large (about one and a half to two hours?), For those who want to immediately after starting the game ... Maybe a little inappropriate.
However, for those who do not want to be a cuckold, there is a mode that can be started from the second part, Umi, so
you can immediately see the erotic scene.
For those who manage to capture, there is also a switch that allows you to open all the erotic scenes in the room of memories.
