First Time Bondage

First Time Bondage! My hands and legs were tied up and I also wear a collar. He pulls me to him and I suck his penis with my hands behind my back. It makes me so horny when he dominates me. He puts me over the edge of the bed and fucks me missionary and doggy style. At the end I get a big load of cum on my submissive dog face. Since my hands are behind my back, he takes the sperm from my face and puts it in my mouth so I can swallow it.
