Been watching a whole bunch of horses and women videos. Aside from the classics being shared, a lot of clearly fake or the horse isn't into it. Of the few awesome videos, I can see the horse was able to penetrate the women and then came, also sometimes the flare pops out. The women seem like they are average sized, with one video where the woman in question seem quite skinny and the added bonus, the horse she was with had the biggest flare ever.
