Blumpkin Stacker
Similar to a blumpkin, a blumpkin stacker is when one man is sitting on the toilet and taking a shit while giving anal sex to another man, who is in turn getting a blowjob from another man. The blumpkin stacker can also involve more than 3 men with the other men simply stacked on top making an anal sex chain
We had an eight man blumpkin stacker yesterday! It was pretty gay
