To say my life had changed was an understatement. I sat in that room while my beautiful wife gave herself to that Big Black Dom. She obeyed and have herself to him totally. He first put a collar on her and tied the lead to the bed head. He then hog tied her. She was then told to lick a butt plug that was offered to her. She licked at it eagerly in anticipation of its intended destination. He then pressed it home. A little whimper was all I heard. He then stripped off. He was massive and she smiled when she saw his cock. He then said to her, "suck my cock!". She readily replied, "Yes Master", and greedily sucked at what was offered. She was trembling by now, and she was flushed like she does with me during an orgasm. He then began to slap her bottom with a paddle like impliment. He told her she was a slut bitch that deserved a spanking. She was asked what she was and she said, "I'm a slut bitch Master". He then removed his cock from her mouth and got behind her and drove his huge member into her pussy. His rhythm began at a slow pace. But as he quickend his pace she begged to have her hair pulled. This he did and fucked her rough for what seemed an age. He dismounted and untied her. He led her from the bed using her lead over to me. In all of this excitement I didn't realise, but I had my hand in my pants wanking. He said to her, "remove his pants and suck him to a finish". Again, she said. "Yes Master". I came almost immediately all over her face. He then kept her facing me, he removed the butt plug, lubed his cock and proceeded to fuck her ass. She smiled at me with cum dripping from her face during this ass fuck. The time in our room continued in this way for the next hour until she had swallowed is load. He tied her to the bed, got dressed and left without saying another word. She just laid tied up to the bed looking at me. She said to me that she was being trained, but I could fuck her if I wanted. Her master gave her permission. We fucked for what seemed an age. She was rampant. From that moment on whenever her phone rang, I would wonder if she was getting a call from him. She told me that she would obey him, but still loved me. Am I weak? I don't like her being his slave, but am turned on by it too.......
