Group Sex

I jumped out of the shower awhile ago, my darling wife remarked, "Dang you're fat, when is the last time you saw your 'unit'?", to which I replied, "been a long time". She then asks,"Why don't you diet?" to which I asked, "what color is it now?". I don't know what her problem is, I gained all this weight so she could have group sex, with me!
