He Got A Limp

I am a 26 year old black brother and I have been dating this brother for about two months. The other Friday night, we decided to finally do it (have Sex). Be mindful that this brother walks with a limp and I have never asked him why. I figured if he wanted to tell me he would. Any ways, we where looking at a movie and getting all feely touchie and started kissing and one thing lead to another and bam we where in the bedroom. He cut out the lights and we took off our clothes, he took off every thing except his sweat soxs. Het on the edge of the bed and gave me some bomb head.  WOW!!! Then he got some lube and XXL condoms and slid one on me.  He throw his legs on my shoulders, one of his legs where a little heavery then the other. I proceeded to enter the holy land, I was trying to take it easy and dude said tear this booty up.  I was so excited that I tried spread the legs apart so I could really get in the holy land.  Next thing I knew I was standing there with a massive hard on and dudes leg in my hand.  His damn leg fell off and I screamed like a church lady getting the ghost while pastor is preaching.  I was standing there in shock holding dudes prosthetics in my hand. Dude had a fake leg. We both started laughing but I could not perform after that.  I am trying to make things work because he is a really nice guy but that damn shit just spooked my ass out.
