I think I have that on VHS tape.
The older guy has ordered a new vacuum pump and cylinder and the younger delivers them to his home.
They soon both have cylinders on.
I remember the delivery guy saying "Well, I got a pretty big dick anyway, do you think It'll make it bigger ?"
I'm not sure if I have a title as it's on a long 3 or 4hr cassette, but I'll try.
