I was messin' around with my girl and we were back on the ragdag. When we woke up in the morning she had some sapvag fever. I told her to get in the shower.

I think I'm going to give up drinking, I met this hagbag at the bar last night. I went down on her but pealing her labia apart was like trying to pry into a mussel. She had the sapvag for sure.

Dude that is one trick ass ho, I know she has the sapvag.
