After a long day of work, keep in mind it's 90 degrees outside, and you shit in the blue house at work. You are rushed so you only have time for a "one timer." You go home from work with some major "swamp ass" happenin and your old lady is feelin frisky! You drop trow and she wants to lick your anus! Nuff said!
Holy shit randy, it was hot yesterday! I went home and my woman was begging for a salted nut roll!
