The other two reviews before mine really say it all.
Only around five scenes, zero choices, you only move the character a few times to the point that you have to wonder why movement was included at all, and a fairly lackluster story of a fertility goddess possessing a kid's penis because he apparently became a member of the priest's bloodline when his mom swallowed his cum while she was pregnant and peeing on the shrine allows her to take control of your dick in that case.
Really bad all around honestly with short scenes, poor design choices, and a reality as thick as water.
If you hold CTRL, you can skip through the whole game in maybe five minutes.
