My Stepmother is my Woman. For as long as I can remember, she has been my primary sexual partner. But for some unknown reason over the past year, she has turned into more of a girlfriend than a wife to me. We have always done things like going out to eat and movies together, but I started getting more into her in the past few months and now I am dying to see what she has in store for me in the future. Cocksucking in foursome is a taboo thing that women usually don't get much opportunity to do with their pen pals, so my girlfriend is the one who forced me to do it..
