Since neither of them have any experience painting walls, they decide to lock the door and strip naked so they don't get paint on their clothes and risk garnering the wrath of Mother Superior. All is going well after half an hour and they have one wall completed when they hear a knock at the door.
Worried that they might be in trouble they run back to their clothes as they call out "Who is it?"
"It's the blind man, I need to talk to you Sisters."
Well they don't see any harm in letting the blind man in, so rather than put their clothes back on and get them dirty after all, they both decide to just let him in.
"Nice tits ladies, where do you want the blinds?"
