I now did something slightly different after returning home. I didn't destroy the picture, any more. I had learned a new way to deactivate it, which I...always did, as soon as I was through the gate.I could feel the magic depart from the picture, and once I did that. I took my two bags of mix to my studio, and set them on a table. I was going to have to get a mixing bowl of some sort to finish these two items and make sure they were working properly.Unless I melted this stuff together, Garretti. Nice was a word that should not have crossed my mind ... but sister did cross it and left me with blueballs.I bought a nice camera, a Zeiss Ikon, with a medium length telephoto lens and became an avid sister watcher. Grace and I are both Gymnasts, although I'm getting too tall for it.Bettie Paige style bikinis are noted for 'slippage' and catching Grace in a nipple slip was one of my favorite pastimes. After snapping through about $200.00 worth of film on Grace from the neck down I started. ..after a moment's silence I saidthat I did not know what to say. She replied that it was ok, that Ishould take my time and that she was a doctor and anything I said wasconfidential.Taking a deep breath I started to talk. I told her that I was atransvestite, that I liked to dress fully as a woman and go out. Sheasked if my wife knew about the dressing and I said that she knew Iwore underwear sometimes but not that I dressed fully or in public.The doctor asked me lots more questions, making lots. She wished he had gagged her so she could scream out her rapture behind the gag, but instead, she had to internalize it and that made her orgasm all the stronger! She sat there, frozen as her legs quivered from the strain and her pussy clamped down on the buzzing hell. Finally, and agonizingly slowly, her orgasm faded and her body returned to her. She sat there, gasping quietly as she gulped down huge quantities of air. Occasionally, her body jerked spasmodically as the last of her throes left.
