I need a membership application form to this club, too.
My wife loves to suck a cock and gets super wet. She is awesome at it.
But she hates having her pussy eaten. I love doing it so she has allowed me to do it a few times and she says she enjoys it but has never cum that way. I know it's not me because I've never had a woman complain about my skills before. Hell, my ex-wife used to squirt all over my face!
At least my wife has an excuse...she blames it on an old aunt who helped raise her as a child and used to watch her bathe and tell her to "scrub your pussy" because it was filthy. She says she can't get over that mental block.
