A blowjob that is truly almost never-ending. A dickcathalon blower is vigilant in her duties to finish but not without her partner. The dickcathalon takes extreme determination, skill, and the upmost endurance. The dickcathalon is approximately 2 to 11.9 hours in length(11.9 hrs being a personal record best) with only two minute breaks every 100 minutes.

There may be certain factors that affect said activity such as "partying" with drugs and/or alcohol.
When we finally got into the bedroom, she began the dickcathalon at 12:36 p.m. And finished at 7:08p.m. No bullshit.
