If you win a game of Go against a busty Go player, I'll beat you to a pulp! - Hiyori Kojima

This time, the super-busty female Go player, Hiyori Kojima, has made her appearance! With her G-cup, voluptuous breasts, she's incredibly alluring. And if you beat her in Go, you can immediately have sex with her! After several matches, I finally defeated her, pulled out my huge, erect penis, and fucked her until I was completely blown away!
