Middle-aged Man's Human Reproduction Plan Trial

Half a century has passed since the end of the war between humans and the allied non-human races. Although the divide between humans and other races remained deep, in an effort to strengthen relations with humans, a sister from another race is dispatched to a human city. The dispatched non-human sister, Erika, and her supporting heroines gradually become immersed in pleasure through intimate interactions with humans.

This non-field roguelike RPG features Feena, a nun aspiring to become a holy knight, as she undergoes a training called the "Pilgrim's Trial."
The game features a simple yet deep adventure system and convenient features like auto-progression, making the gameplay enjoyable.
The erotic content is centered around intense interspecies sex, anal play, and humiliation play.

Once sworn enemies, Slavs and Lizards made peace for the glory of the Holy Stand! Two species coexist in harmony, enjoying life of passion and lust with each other. Exactly as father Perun willed it... Although it is only true for a single village. For now.
Ratibor, the champion of Slavs, and the warrior lizard Viente travel to the Lizardwomen capital, Atlantis, to seal an official friendship agreement between the peoples and spread peace and love into every corner of both Hyperborea and Atlantis.
But can the century-long grudge between lizards and Slavs truly be cast aside? Or is it just a calm before the storm? Might Mathematics, the goddess of lizards, be planning something? Or maybe there is some third party seeking to shatter the fragile peace?

If you manage to escape from the boss monster, you clear the stage.

We are a family of five, with three daughters and both parents still alive. We live in a detached house not far from the station, and except for the fact that our father is away working away from home, we are a picture-perfect happy family. That is the Sera family.
