It is called the SLURP-ABILITY SCALE. I try to rate each cock I suck on this scale. In case you didn't know, I suck a lot of cocks. Why? Because I love having a cock in my mouth. Big meaty cocks are the ones given the best ratings. It is a 0-10 scale. I have been thoroughly gagged by thick and long 10 cocks. Those my favorite.
I know that some people would rate me a 10 on the SLUT-ABILITY SCALE. If loving cock in my mouth makes me a slut, then I will gladly accept my slut rating. They don't call me "Blowjob Barry" for nothing.
