Boyfriend eaten by best friend!! Should I confess it to her?

What kind of crazy, long weekend was that? I was out and about in Berlin with my dirty hobby for a super hot day! And of course I wanted to have a bit of a long weekend! My best friend and her boyfriend accompanied me! We wanted to have a really nice day of sightseeing! My friend is just as forgetful as me and forgot her wallet in her room. But since she was having a pretty good chat with another lady down in the lobby, I was so nice and he just wanted to get the wallet! Of course I knew her boyfriend was still in the room, but I didn’t know what he was doing. I really caught him in the act when he was comfortably massaging his cock! Now to be honest, as a good friend, I can’t just leave it like that, can I? I would say that I went on the sightseeing tour with extremely wet panties! Take a look for yourself why the panties were so wet.
