It has been a month since this happened and I still can't believe what I saw and I still can't believe my reaction to what I saw. I shared my story with my mom (62) but I'll tell you her reaction a little later. My daughter Tammy is eighteen and I consider her a very well-rounded, normal, everyday type person. She does well in school, has her fair share of friends and maintains a part-time job after school. A month ago she came home from school and out of the blue she asked me if I wanted to see her do a "real cool dance." Tammy never demonstrated any dance skills before so this took me by surprise. I said "sure." and sat back and waited while she put a disc into our sound system. I should now tell you that Tammy was wearing a nice blouse and a somewhat short skirt. She has a lovely figure. I did not recognize the music but it was clearly meant to be danced to. It had a rather sensuous sound that's hard to describe. I liked the sound. Tammy started her solo dance and I thought she seemed quite light on her feet. I was pleasantly surprised at this point. As she danced she kicked off her shoes and was now barefoot. As the music and her dancing continued I suddenly realized that she was trying to act sexy and provocative. I was just a bit uncomfortable with this. Then I became real uncomfortable as she removed her top and was now dancing in her lacy black bra. After a minute or two she unzips her skirt and is now in the middle of the living room in bra and matching panties. As uncomfortable as I was feeling I was also experiencing the sensations associated with arousal. My mind told me to tell her to stop but nothing came out of my mouth. I was actually waiting for more. I didn't have to wait very long before she undid her bra and very slowly she removed first one strap and then the other. Inch by inch she pulled the cups down from her tits until finally the bra was off. She tossed it into my lap. As she moved to the beat of the music she began to fondle her tits as well as her nipples. I was now quite stimulated sexually and couldn't take my eyes off of her tits. Actually, I wanted to stand up and fondle them myself. Next, she very slowly and very suggestively pulled down her panties. I hadn't seen her naked since she was eight. She took her time and then dropped them into my lap. Her pussy was totally bare with about an inch of her inner lips protruding. Her movements now were extremely erotic. If I were a man I'm certain I would now have a rock hard erection. I was now totally arroused and had to really work to contain my emotions. Tammy then continued to dance very erotically while running her finger briefly through her slit. I had never seen anything so erotic before. She gyrated her hips and thrust her pussy toward my face. I was now as arroused as could be and had to force myself to remain calm and in control of myself. She then turned around and gyrated her rear into my face. Her butt was absolutley lovely and I wanted so much to reach out and squeeze her cheeks. She continued to fondle her tits and nipples while pushing her pussy toward me. She whispered to me "kiss it, kiss it. I did not! Finally the music ended and Tammy very calmly took her panties and bra from me and proceeded to get dressed. She then asked me what I thought of her dance. I just said it was very erotic and possibly pornographic. I didn't tell her that my heart was pounding and that I wanted to bury my face between her legs. She then told me that she and friend Camille had "practiced" this dance for a couple of weeks. She said that Camille's mom showed her the dance. That doesn't surprise me in the least. I was in shock at this point and really didn't know what to say or do. However, it wasn't over just yet. Tammy told me that she would like to do her dance for her grandmom. I said absolutely positively not under any circumstances. I was mad and told her that her dance bordered on total pornography. She was clearly upset and told me I was a fart. I shared all of this with my mother and much to my dismay she said I probably was a fart and that she wanted to see Tammy's dance. I must admit that since the dance I have masturbated several times to visions of her erotic performance. Tomorrow she does her dance for my mom. This is nuts!! Next she'll want to dance for her dad. What do I do then?? I'll watch her dance again tomorrow when she dances for my mom. I don't want this to get out of control.
