And I loved it. Adrenaline was pumping through my veins and I felt more alive than I had in over a year. I quickened my pace and brought my other hand...up to play with his balls. By the way he was moaning I could tell he wouldn't last long at all, so I started humming around his cock and the vibrations sent him over the edge. I immediately sucked harder, swallowing every drop of his spunk. I had never realized semen could taste as good as it did at that moment.When he finished coming, I tucked. And it was done. Painless, as every intermediary frame step of the transformation was stable, and she could have stopped at any one of them, and she did pause at a few useful humanoid ones. That one there, it was perfect as her dragonkin natural-form.It took very little time, and she evidently could control (at least on some level apparently) her size and mass, because while her mass was greater, and while she still fit in the room (barely- although admittedly it was a rather small room) she. I stood up and looked at myself in the full length mirror. My body was looking good, I had worked real hard that whole year with the sports I took. My legs were like rocks the thigh muscles were like tree trunks and my tits and ass were enough to have any man drooling. I started to undress and while I was undressing I lost control and started caressing myself. I slid my hands down my belly into my already wet underwear. I slipped my finger into my pussy and started to rub my clit. Man it felt. You know the old war film 'Ice Cold in Alex'? Where they are stuck in the Western Desert in an ambulance with a German spy, and all they can think about is having a cold beer if they ever get out of their predicament? And then the final scene, where they are in the bar, watching the lager being poured out of the bottle, and then drinking it, and you can almost see it coursing through their veins like a tonic? Mind you, my wife says that I now only watch the film to letch at Sylvia Syms - there.
