They're sort of in a series, I believe the first one's called "Steven and Colin", about these two brothers named Steven and Colin who get tied to their beds, and then wedgied and tickle tortured by their older cousin James for an afternoon.
The second one I can't remember the name of, but it involves James and a friend coming to "look after" Steven and Colin for a weekend, and doing more of the same.
I know this isn't much, but hopefully someone can point me in the right direction? thanks.
