イったら〇ぬバトルファック ~メスガキパイズリ敗北～

I was suddenly trapped in a mysterious space with nothing but a single bed.

According to an announcement by a mysterious voice, if I beat my opponent in a game of battle-fucking, I would be able to get out of here.
Of course, there was no way I could take such words seriously, so I tried to find a way out.

But the cocky brat next to me seemed to be in high spirits, pushing her huge boobs against me in a way that even adults would be envious of... I'm not gonna let that naughty girl's tits turn me on! I'm gonna make her cum and leave this place!
