The best with closeted married guys IS to let them waiting, 2 or 3 weeks for a sucking or fucking session ! They get so madly excited that will suck you dry, no condom and even swallow.
Well, that was a first. First time I've seen a cocksucker take off his watch and use it as a cock ring. Oh, btw, I'd love to suck that guy off too! Yum!
The best blowjob you will ever receive will always be by a closeted fag. Usually it's someone who's married and rarely gets to play, and they'll swallow every drop once they do. They crave pussy less and less with each visit.
I should know; I am the closet fag.
