Just dogs, but played with several breeds. A bad temprered shepherd, a sweet lurcher and lab, and a very enthusiastic rottie, All those just mounted and fucked without knotting but my heart was taken by the first dog I got to play with regularly, a mastiff, who was just the right mixture of dominant and sweet. Fucked like crazy then just rested into the knot licking my face while his amazing knot emptied int me while we were knotted. Just the best. He also loved kissing and my drinking his cum. Miss him like crazy, he developed. grass allergy, became really ill and had to be put down. I hope one day to meet a dog as lovely.
