I always considered myself sort of a Truth Avenger whilst crotch-slamming married chicks. They way I looked at it (in an admittedly fucked up view, but entertaining nonetheless), there are a shitload of ridiculously irresponsible and immature "adults" in this country who get married and shouldn't be, thus causing years of agony and displeasure for themselves and others. Because of their shortsightedness, I never felt bad engaging in sexual trysts with married/engaged chicks. Obviously, contracted commitment was the wrong move (otherwise, why is your girl servicing my autoerotic asphyxiation fetish while you're at work?) and I was happy to end the aforementioned misery for that couple, or at least be a catalyst for that eventual termination of vows.
In other words, if you're too childish to make adult decisions, my cock is more than happy to assist.
