About This Game

A passionate, one-night affair with your son's friend's quiet, unassuming mom—

■ Story

You glance at your phone and see an unfamiliar name on the screen.

It's your wife's friend—a mom whose child is friends with your son.

You had exchanged contact information because your children often spent time together.

But the message contains just one sentence:

"Would you have sex with me?"

And nothing more—

■ Concept

The Affair Ryokan is a 3D sex simulator centered around the raw desire between two mature adults.

An affair allows you to indulge in reckless, passionate acts that you could never show your wife or husband.

Give in to the desire you've both been suppressing, and lose yourselves in a night of uninhibited passion.

The game was created to capture the slightly vulgar, raw, and intimate atmosphere of a secret affair between two married adults at a traditional Japanese ryokan.

■ Content

Enjoy an intimate night with the mom at your own pace.

• Freely choose between voices recorded by four different voice actresses

• Costume customization and free camera control
