The fine European art of performing the Glass Bottom Blumpkin includes 2 females, 1 male, and a roll of stick or non-stick saran wrap. The male receives a ravaging blow job from one female, whilst the other female, laying on her backside with her dome piece saran wrapped (stick or non-stick), places her face strategically under the male's external anal sphincter. As the male approaches the ultimate climax, he sprays his doo doo butter on the second females saran wrapped dome piece.

A variation of the "Roman Spider Dump" mixed with a "Double Blumpkin."
