Koko and I have been dating for a few weeks, but we haven't even kissed yet. I'm still a virgin, so I didn't know how to approach her. Then Koko suggested, "Let's have our first kiss on our one-month anniversary," and we innocently promised with a pinky promise. Before our anniversary, Koko has a tennis club training camp, but it turns out it's a sex club. Without my knowledge, Koko gets completely drunk. She ends up getting creampied by a group of guys while still in her tennis clothes.
