I did the same thing. And at the same age. It was our male family poodle.I must've been 7 or 8 the first time I had got the family dog to lick my cock and balls, that happened several times over a few year span until I tried to penetrate my girl at around 13. I haven't had any experience since sadly.
I'VE started in zoo at 9 yo with dog. Now at 47 love sex with horse , Have any other started so young? Always straight love zoo love females!
