playing with the handcuff

This is my first post on this site, so I hope it’s in the correct section. I was wondering if anyone else has accidentally experienced the same issue that I will describe. I was very naive at the time and have learned a lot about selfbondage since. Anyway I finally built up the courage to buy my own pair of handcuffs, I purchased these new cuffs, they were Smith and Wesson hinged handcuffs, the type that didn’t have the chain linking the two cuffs together. I thought these look different to the normal cuffs and will be very secure; I’ll have a lot of fun handcuffing myself and maybe my b/f with these I thought. So after buying them and taking back to my flat I had to try them out on myself and my room mate won’t be home for 1 ½ hours, what could go wrong? I first of all I played around cuffing my hands in front of me, the feeling was indescribable. Then I took the handcuffs and put them on behind my back, this is where it all went wrong. After walking around the house for a while it was time to take the handcuffs off. I took the key, walked over to the mirror turned around and attempted to unlock my handcuffs. Looking at the cuffs in the mirror, I tried to put the key in the key hole but it appeared to me that the key holes were facing upwards, away from my hands and I went into a panic as I realised that I was not going to be able to reach the key holes as these handcuffs were hinged for this very reason. I tried and tried but it was not possible. What made it worse was I hadn’t double locked the cuffs either and my combination of twisting my wrists around and rolling on the floor trying to slip them over my backside had resulted in click, click, click, click (I still had a skirt on too) both cuffs were extremely tight and the palms of my hands were now facing outwards. I had no option but to sit on the couch and wait for my room mate to come home, she did and laughed and took photos of me before releasing me.
