Disgusting because seeing a woman gag and have tears coming out of her eyes is something I'd normally find distressing and in this situation repulsive. Disrespectful because there does not appear to be any pleasure on the female's part and the act looks for like an act of aggression or a display of dominance. Probably fine in relationships where both partners are okay with it but expecting it off an escort is something that I'd personally find questionable.
Maybe I'm just being old and prudish.
