Shot in 4k 3840 x 2160 60fps with Canon EOS R7 - It looks like you brought Rex to the vet here for a semen sample as he has a little "play date" with a lady next week? Very responsible of you to do so and get everything checked out before breeding! I'll take him back and let you know when hes all finished up! Rex's cock hardens instantly when I touch his doggy cock, its so big it barely fits in the collection cone. I run my hand up the length of his shaft until I reach his knot, and its already pulsing in my palm... squirting sticky nut into the collection cone. It doesnt take much time before hes filled it up and I can't do anything but stare in awe at it and talk about how badly I would love to feel his cock inside me. How much I'd love to be the bitch underneath him, how much Id love for that knot to get stuck inside of my wet pussy and feel that cum shooting inside of me. Nope... nope... have to be professional today, today is just about collecting the semen sample. But maybe I can talk Rex's owners into bringing him back one day again soon for some more "private" testing.
