My wife was fucked just three times before we met by the her first love. She never had a penetrative orgasm before me. And since then 27 years later she had become multi orgasmic and for the past 12 years a shared wife. One child only and her pussy really hasn't changed much if at all in tightness. She had 15 different guys in those years, five now whittled down to become regulars. The guys have all been average some thicker than others, but everyone remark how tight she is from the initial start of the session, and even though she cums off several times she remains tight. We put this down to her orgasms, and the contractions she gets during orgasm that have kept her vagina in excellent condition.
