Mike W's Grandfather emigrated to Canada by blowing down his own dick really hard then using his own inflated balls as a raft and amputated donkey dicks as paddles. He also drank his own sperm for food, starting the family traditions of W's drinking sperm instead of milk.
The fight would be never ending as the both love getting rear and naked without the choke part, that's foreplay
They say that asphyxiation increases the intensity of an orgasm so I wouldn't doubt that the choking is also part of the fun.
