I've always found the bigger girls are usually better at sucking cock. They are usually used to being overlooked and pumped-and-dumped by horny guys, so many of them develop a fixation with making men happy. If you're ever at a club at kicking out time, pay attention to where the tubbies are, they always give you a wild ride.
I would love to have a wife like her and eat her pussy and ass while she sucks all of those cocks. I would kiss her after they explode in her mouth and have her spit some of that hot cum on my cock to use as lube to fuck her while she continues to suck more cock.
There used to be a gloryhole in the sex shop round the corner from me in Hamburg. The woman that ran the counter was very obviously a butch dyke. However, if you were in the booth, getting your cock sucked, you could signal to her from the booth, and she would come close, and show you her ass and pussy until you came. After you came she used to look at your cock and say "pathetic!". Lol.
