I had spent almost 2 hours on my knees at the glory hole sucking every cock I could find. My face was a mess. My chin still dripping with cum. I was getting ready to leave for the night when I saw your gigantic black cock. The largest cock I've ever seen in my entire life.
Part of me said "No, I'm done for the night. Besides, this is a monster cock." but yet another part of me said "This is a monster cock and I need to prove I'm an amazing cocksucker."
Guess which voice in my head won?
So I move back to the hole to the already hard BBC. I put my mouth on the head and it BARELY fits in my mouth. I hear a low satisfying moan from the other side of the wall.
I'm not sure if it was the moan, the feeling of power I get when sucking a cock, or the challenge of making this big fat dick cum, but I wanted more.
I started moving my mouth VERY slowly down the shaft of this cock. Stopping to flick my tongue under the head in that sensitive spot. The moaning was back and I loved it.
I kept sliding my mouth closer and closer to the base. Going slow so I didn't gag or choke, giving my throat time to accept the girth of this cock.
I could feel my throat bulging where the head of his cock was moving slowly down my throat, and I was proud of myself for not gagging.
Before too long I felt his pubic hair on my nose and I kept moving until I had as much of this behemoth cock in my throat as I possibly could.
I knew I couldn't bob up and down on this cock or I should choke for sure. And that's not sexy at all.
Instead I started swallowing. Not really swallowing, but the muscle movement in my throat like swallowing. I did this 3 or 4 times before hearing "Oh holy fuck yes!" from the other side of the wall.
I started doing this swallow movement harder and a little faster, and he pushed his cock as far into the glory hole as possible.
After 5, maybe 10 minutes, I felt his balls tighten. I felt his shaft swell in my throat. I heard his breathing getting faster and deeper.
