You definitely shouldn't feel guilty. In my experience, wives who cheat on hubby seem to have much happier marriages once they come to terms with and give into their sexual needs. The only real challenge for you is to find someone you can see regularly, who won't get overly attached (assuming that's what you want), and who has a suitably big cock for you to ride.
One of the biggest kinks that cheating wives seem to enjoy (again, just based on my encounters) is to meet with me and get creampied a couple times before date night w/hubby. They get seriously turned on by the secret thrill of having another man's cum inside them while hubby is romancing them ... I have to admit, I find it rather hot too
