FAITH TEST! Will you pass it?

My best girlfriend asked me for a favour. She has the feeling that her boyfriend isn't faithful, but she wanted solid proof, because it could be that she's wrong and it's just a stupid feeling. She now knows about my little hobby here and asked me if I could test her boyfriend for her. Fine, I thought to myself. I have nothing to lose, I just hope for her sake that he doesn't go for it. But I already know him a bit and I don't think he's the type. He seems very sweet and loyal. So I asked him to come round and of course he did. But what happened next...! Everything just went differently than expected! HE surprised me so much! I really hadn't expected THAT... I hope YOU like this little loyalty test :* Kisses, Maja
