Mom's who drink too much

Was in some online forums a few years back and I was shocked. A forum for americans based in some southern states confessed to having had sexual encounters with their own mother’s after the mother’s blacked out

You know some men just can’t resist a drunk or blacked out woman even if it’s their own mother. I can’t imagine having sex with an unconscious person isn’t it like necrophilia? If you can rape a corpseb4 rigor mortis sets in who is your mother?
