He positioned the machine in between my legs, he reached up under my skirt and pulled my thong down my legs, taking it off of me, then he attached two more cuffs to my legs then leashing them to the machine, ensuring that I couldn't move my legs at all. He then placed something around my little dick and balls that I couldn't place. He put a camera on my night stand, the light went red. He went back to the machine, I turned to see him securing on a small pink dildo. I guessed it was just slightly smaller than my brother's dick.
