Felching For Duckbutter 

The two part act of sucking semen out of the anus with a straw while maintaining enough of a vacuum to get the greasy, and sometimes chunky duckbutter that runs along the taint.

Being careful not to miss a drop, and priding himself as a pro at Felching For Duckbutter, Gabe Athouse aimed his straw and inhaled every last drop of the load he left as well as the grimy, nutsack buildup.

Duckbutter 

The cumulative collection of body sweat, crotch sweat (including vajelly and smegma), ejaculate, anal seepage, and lastly, saliva, which occurs on the surface underneath a sexual encounter.
May also be found in the underwear after sexual encounter.

For the love of Christ Pamela, I'm not sleeping on the duckbutter spot! It smells like a poop infested basketball court next to a fish market!
