Hehe...he spanked you on that one old man.
And Doc so loves to be spanked. Hehe, put him across your knee and paddle his butt with your open hand and he's in 7th heaven.
The probem I'd have with that is those rubbery latex undies he likes to wear... they'd get all hot and sticky after a while, and I wouldn't want them sticking to my hand, much less my knee.
Yeah, I know, I'm up for another cruel, yet entertaining 'shop' as payback.
Oh well, there'd be no fun in it if there weren't a nutty reply.
