It was immediately pleasurable as his head swelled inside me locking him to me as surely as the dogs had knotted to me just inside of my vagina. The d...fference he was knotted to me inside my womb through my Cervix. If I was to force myself off, my innards would be locked onto the horse and I would loose my lower organs through the opening it would make. Needless to say I was thoroughly enjoying the penetration as his precum was beginning to flow. The handler gave him his injection and he. . you don't understand..."His words were barely audible, and Niven ignored them completely. Obviously Mark didn't suspect that, in not fucking his wife when he had the chance, he too was more ready and eager to relieve himself."You want to fuck me, don't you?" Niven asked in a mesmeric voice. "You want to fuck me, and I want to fuck you too. Why do you think you're here?"Mark thought quickly. He really hadn't wanted to fuck her, he decided. He had just wanted someone to be with, and she had. I had an arm across her breasts and a leg over her thighs. This was a flip from what was the norm. She laid there feeling the warm arm and the warm leg touching her and the warm hard penis pressing against her hip.She was thinking about how nice it felt and that she envied me for being able to feel like this every morning. Kendi was now fully awake and enjoying the wonderful feeling and then it hit her. She had to pee. She realized that this was how I felt each morning. The urge was huge. She. Then she felt up to the head of the bed and under the pillows. Her hand returned with a small cloth bag."... under the pillow are the toys..."She pulled the cord to loosen the top and then dumped the contents out upon the bed before her. The clothe bag joined her clothing.I heard her laugh and her voice playfully spoke through my speaker, "Oh Master, you naughty boy!" Boy indeed! I will remember that the next I have her over my knee - that alone will get her five more!She pulled the next note.
