Yeah I would got tied by a fixed mastiff but if you are going to take the knot, try to get him inside all the way cuz when he swells it's gonna be painful if he tries to pull out. Was stuck to him for 30 minsHi
Have you ever had sex with a Mastiff male dog? I am very interested in its penis couse I read about it and it's the biggest one on the chart.
Would you (as men) do it with a mastiff?
