Slippery Spelunkin blumpkin
A mix between a Slippery Slepunker and a Blumpkin. It's when you shit into a condom while someone is giving you head on the toilet. Then you fuck the person giving you the Blumpkin.
Last night I was giving Tom a blumpkin and he fucked me with his shit. It was warm... Oh, Tom gave me a Slippery Spelunkin blumpkin last week. So sneaky!
