There's a secret place that's secretly the talk of the class... It's a ruin that's a hangout for sparkling first-rate girls & wild boys. I don't know what's going on there... but a nearly-virgin innocent girl was half-dragged there. In front of such an innocent girl, men and women are doing erotic things! What! Are they doing it even though they're not lovers? And multiple partners? The innocent girl is panicking and frothing at the mouth. Then a man's hand reaches for her crotch! What! Am I going to participate too? Swept away by an atmosphere where I can't say no now, I have my first multiple play... The innocent girl who had sex with several men that day. Once you cross that hurdle, there's no stopping it! Before I knew it, I joined the ranks of lewd women who are rushing down the path of slutdom! But honestly, I don't mind, because it feels so good.
