The fidelity test - is her fiancé fucking me now ?

What wouldn't you do for a good girlfriend, because she was really desperate and didn't know what to do. Luckily I had an idea. My girlfriend got engaged to her guy and the wedding is coming up. However, she thinks he is cheating on her but she just can't prove it to him. Of course he denies everything but that's where I come in. I volunteered to be a decoy and we set a trap for her guy. Let's see if he can resist hot lingerie and high heels or if he really is such an idiot as I told her from the beginning. Because I've been of the opinion that he's cheating on her for a while but she didn't want to believe me. Now I'm doing the ultimate fidelity test and hoping not to crash the wedding !!!! I really went all out to seduce and provoke the guy.... She got the answer promptly by mobile phone, what a great guy her fiancé is ;)
