I had a dream last night that I was standing at a urinal in restroom. I had my dick out, but I wasn't peeing. Instead I had a thin wire looped around it just below the head. I have the wire a firm quick tug, and the head of my dick hell to the floor. No blood, no pain. I looked at my dick and it appears the same except it is blunt on the end, again no blood or anything like it was made that way. 

I picked up the head then panicked, thinking my girlfriend is going to be pissed at me. I just made my dick smaller. I inserted some kind of rod into my urethra and then slid the head onto it to make it look like it was still there. I walk out of the bathroom and meet my "girlfriend" outside. As we were walking down the sidewalk I feel something against my shin in my pant leg, and then it falls out on the ground. I tried to pick it up before she saw, but it was too late.

I woke up just after she said "you have to be fucking kidding me"

Weird funny dream
