When one is engaged in anal sex and as they are thrusting in and out of their partner's anus they
look down and notice
some shit on their dick. Suddenly the energy and desire for anal sex is
diminished greatly to the point of becoming semi-erect.
Jim: Dude, I so pumped last night. I had a hard-on that wouldn't quit and I was fucking
Jane's ass. Then I noticed my cock was coming out dirty and I just lost it. Started
going limp. Lost my drive. What a bummer.
Bo: Damn, bro. Total
brown out!
