Only you (jap) by Soft Circle Courreges - Adult Sex Game

This is a simulation game where you can customize your lover however you want before having sex with her.

"I don't want to end up with you like this"

My girlfriend revealed that she had been cheating on me.

"Because you have been cold to me lately..."

"So if nothing changes then there's a good chance you'll cheat on me again?"

She wouldn't state that she wouldn't.

Fine then, but I won't break up with her yet. First I'll totally break her in, giving her the ultimate pleasure. Soon she won't be able to think of anything other than having sex with me.
