Smaller Cocks Are Better

I had a friend that I used to blow on a fairly regular basis, who was a bit on the small side (4”). I could suck him for a while and never get tired.

Then I met this other guy who turned out to be very large, and man, it is work sucking a big cock. My jaw got tired after about 10 minutes, and it was a struggle to keep my teeth covered.
Big cocks are nice, but I’d rather suck off someone a bit smaller.
