Wooden horse pussy torture

I use a triangular horse with a 90-degree angle, with sides that 12 inches long. In my experience, this design is more painful for the girls who have ridden it than for me. Part of the difference may be hip anatomy, as with the triangular design I don’t find it particularly hard to support some of my weight on my thighs indefinitely. Usually for girls after about 20 minutes their pussy is taking all of it and the pain ramps up considerably.
