When a person is sitting on the toilet having a shit and someone sits in their lap to recieve the shitter's cock in their ass. Double blow refers to excreting shit and blowing a load in someone's ass at the same time.
I was horny for some ass and ready to take a shit, but had minimal time before work so I called my girl into the shifter for a Stinky Double Blow.
