My wife knows that I want to suck cock but hasn't yet offered her consent. But then she hasn't flat out said no either. One day, should I ever get the opportunity, I might find out how she feels about it. She certainly gets hot on the 'idea' during pillow talk etc. She will, for example, pretend to be a guy as she blows me. Fun but of course that doesn't satisfy my urge to suck cock myself.
