He had the right idea and chickened out. He was getting a perfect fuck and jerking off while he was getting humped. But he didn't let the knot tie in. He missed out on having all that cum fill him up. Letting the knot fill him and finishing off while being knotted. A wonderful opportunity wasted.

I did that once a long long time ago. I would love to have a dog cock fucking my arsehole again, I would definitely wank like that. Be even better if I could fuck a dog cunt at the same time.

Send me a message if you want my ass

got to try that

Best feeling ever when you jerk off while you are getting fuck by a dog !!! I just love it
