When I was like 15 or 16, I was home alone. So naturally, as a teen who is home alone, I'm masturbating in the living room and as I do that, my dog came over to me and started sniffing. I stopped her at first, but I was a virgin and had never done anything sexual with anyone. I wanted to know what it felt like to be licked and I figured it couldn't be too different and it shouldn't be a problem if the dog was willing doing it. So I let her keep licking me. It felt incredible and she made me cum pretty quickly. Eventually I actually did have to stop her because my clit got way too sensitive. I ended up doing it pretty regularly when I was home alone until I moved out. It's been awhile since I've done that, but now I take testosterone and I'm even more horny and it feels like the interest I already had in zoo has expanded to wanting to take a knot as well.
