Albeit sacreligious in nature, this act is related to the dirty sanchez and the dirty rodriguez in that it involves anal sex. Specifically, this involves having anal sex with a nun, and after having nutted profusely and with reckless abandon in her ass, withdrawing one's cock from said ass, and demanding that the nun turn around so that a dark smudge can be placed on her forehead (similar to the ashes placed on Catholics' foreheads on Ash Wednesday in any given Roman Catholic Church). The dark spot being made cock-borne ass matter from the man's dick.
Speaking of a Dirty Ash Wednesday, yesterday afternoon at the Church Bingo, I ran into my former Mother Superior and started reminscing about old times. Afterwards, we hooked up which led to me giving her a Dity Ash Wednesday - for old time's sake.

Man...I'm exhausted...my roomate was out of town all week and he left his porn stash out...between the mags and the 'net, I had a three-day wrist-a-thon. I musta busted a nut 22 times in three days. I'll have to remember to mop up the love stains before he gets back into town.
