The first time I properly met someone with the expressed intent of trying it. Up until then I was never sure whether I would appreciate actually experience doing it as much as the idea of doing it.
The first time I met the second guy his boxer pinned me naked on the couch. First with his two front legs and then he preased his chest to mine making sure his cock nestled comfortable next to mine. I ended up jusy massaging his ears neck and back gently until he decided he liked and trusted me enough that he passionately stared into my eyes while he kissed and made out with me for well over an hour. I was asked to move to the floor and then I got to experience performing oral starting with just the tip. It ended up with me having his shaft engoring and sliding deep into my throat coating it with this thick hot feeling and only tasting it when he pulled back into my mouth. It was then I knew that beastiality and my attraction to male dogs is a central piece of my sexuality and sexual attraction.
