Your mom? Cool Hand Lube fucked her.
But she's married! To my dad!Edit
Doesn't matter. CHL satisfied her in ways that your dad just isn't capable of anymore. Sorry.
She's actually dead!Edit
That explains why she didn't move around much. And why her personality was a bit...dry. Actually, switch out "personality" with "vagina."
Who else has he fucked?Edit
You really want to know? Ask your wife. (He's actually really only been with three girls. Dude talks a big game but he can't back it up. He likes to over compensate.)
