I used to have pics of a 3 pt buck that was following around a 2 pt buck and tried to mount him at least 5 or 6 times. Wish I could find them. Maybe they came from the Capitol Hill (Seattle) or the downtown Olympia herd.
Are you sure it's 2 does? Not a small spike or button head?
After I thought about it. When I used to raise Meat Rabbits the Does would do that every once in a while. Probably a dominance thing?
