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.

In a world where human farms are operated out in the open. The main character, who wants to become a ""milker"", visits a farm for practical training.
While the trainees tour the facilities, trouble occurs!
The training session ends abruptly, and, as our hero wanders around the facility, he meets a slutty older sister-type cow named Ayana.
Ayana ends up liking him and offers a more hands-on practical training!
Will he be able to milk her well?"

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.

The tight hole is a dungeon so narrow that you can only crawl through it.

You can’t move properly inside the hole.
Use left-right movement and crouch/stand skillfully to dodge enemy attacks.
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.
