Karen thought about it for over a week before deciding to go ahead with her plan. It was her birthday and she wanted a special present that only I could give her. She told me that I did not have to buy her anything this year, but that I could give her the best present ever by agreeing to act out her favorite fantasy. I was a little apprehensive, but the glazed look in her eyes won me over and I agreed to do as she desired. Delighted, she told me that I would not regret my decision. She spent the next five days preparing everything for her birthday 'party'.
Her birthday fell on a Saturday, giving the two of us the whole day together. I awoke that morning to find her sucking my aroused cock. Her head bobbed up and down the length of my cock, coating it with her saliva, allowing her hand to slide up and down the length of my cock in concert with her talented mouth. As I neared orgasm, she let my cock fall from her mouth, running her tongue all over the smooth, sensitive, engorged head. She ran her tongue up and down my cock, exciting me beyond belief. She had never really enjoyed sucking my cock, only doing it once in awhile to please me and she had never let me cum in her mouth. She began to suck one of my balls into her mouth, causing me to moan out loud.
Sensing the control she had over me, she told me of her plans for that evening. I wasn't sure how I would react to her fantasy later that evening, but I told her that I was ready to fulfill it for her. She shivered with delight and resumed sucking my cock. Deeper and deeper she took it into her mouth, bring me close to orgasm once again. Sensing my imminent release, she looked into my eyes and told me to cum in her mouth. With one hand caressing my balls, she sucked me with wild abandon, my cock erupting in her mouth, coating her throat with sweet, sticky cum. I couldn't believe my good luck; fullfilling her fantasy was a small price to pay for getting a blowjob as good as the one I had just received.
Later that evening she had me undress and take a shower. 'Make sure everything is nice and clean for me', she said. I relaxed as the hot water eased the tension from my body. Lathering myself up, I did as she requested, washing every inch of my body. I closed his eyes and began to rinse the soap off my body, using the handheld showerhead to rinse myself clean. Just as I returned the showerhead to its holder, the shower curtain was violently ripped open. Before me stood my wife, clad in only a t-shirt and jeans, holding a very sharp knife. 'Get out and get on your knees', she demanded, waving the knife in a very threatening manner. Not wanting to make her angry, I complied with her demand.
