Grace and I have been married now for almost three years, and we’ve been best friends for more than five. It’s our philosophy that anything goes when it comes to sex. We have only a couple of rules: Stop if either one of us says so, and be gentle. Recently we’ve discovered that with the proper lubrication and stimulation, it is possible to truly enjoy anal penetration.

Last Friday Grace had to work late at the office, and I was generally bored, having put in my hours at the computer earlier in the day. The prospect of an evening alone was not something I was looking forward to when the phone rang and I heard my favorite voice saying, “Honey, I should be finished here about nine tonight, and I was just thinking how nice it would be to know you were at home getting ready for me.”
