A girl who has a sex friend seems like she can get laid right away, right? So I started my investigation by pretending to interview people on the street and asking, "Do you have a sex friend?" I asked a girl who said she had a sex friend to call the other person, and I invited the two of them to a hotel, saying I'd pay her a fee if she told me about it. I managed to get her to talk to me about having sex with her sex friend, and then the cameraman joined in for a threesome! She was a born pervert who loved sex!
