Double Upper Blumpkin 

A slight twist on the original blumpkin.

The double upper involves a male taking an upper decker while a female is taking a dump in the main bowl of the toilet while facing backwards. While all this is happening she is blowing him.

My buddy and his girl would have a few drinks after a night of eating hot wings. When they got home they were both so horny and had to shit so bad that it would inevitably turn into a double upper blumpkin.

Double Reverse Blumpkin 

The act where the woman is taking a shit on the edge of the toilet while the man, or another woman, is eating her out. An easier, but messier variation is where the woman shits on the man while he eats her out.

This is not to be confused with a Blumpkin, or a Reverse Blumpkin, which are two different, but closely related things.

The woman was tired of giving her husband blumpkins all the time, so she forced him into a Double Reverse Blumpkin.

One participant is sitting on the upper deck of a Toto Toilet while your partner is sitting on the lower deck; with the seat warmer on and the water blasting against their genitals. The upper decker is receiving Fellatio while both parties are passing a Cleveland steamer.

Guy 1: Gawd! Julia is such a basic bitch, i cannot stand her.

Guy 2: Sure, but at least her parents are rich enough to afford a Toto Toilet.

Guy 2: She totally gave me a Steamy Upper Decker, Double wet Blumpkin
Guy 1: Legendary!

Blumpkin Double Duo 

When a man extracts his fat monkey turd and shuvs it up the woman's pussy while she is giving him head. Difficult to do.

It started out as a normal blumpkin, but then I turned it double duo.

A double donkey blumpkin is a sexual act wherein two men sit on toilets facing each other, and recieve fellatio as they evacuate their bowls. Both men should climax simultaneously, and at the moment of climax punch their partner in the occipital lobe as hard as possible.
