I love glory holes and when I suck a really nice cock, I slip a piece of paper with my cell # on it and tell the man I just blew that he can call me anytime for blowjobs. A couple have called and I have them over to my place. It works very well.
I love when one of my gay FWB's calls me wanting a blowjob and when he slides his soft cock in my mouth surprises me by allowing me to swallow his piss before he gets hard and cums.
