Keyser Coffee Filter

Similar to other sex acts known as coffee filter but with a dramatic twist reusing the undies for an actual coffee filter
Charl: I was giving Davit a real coffee filter with the Taco Bell I had eaten and stained up my tighty whities good. After our sexual frenzy was over I washed out the tighty whities and since they were already stained I used them to filter my coffee grounds in the percolator because I had run out of paper ones.
