Don't recall seeing this posted, but forgive me if it was.
A lube vendor created a giant slip and slide using their lube - and filmed a great little video. (Note, clip is co-ed)
Apparently there is an x-rated version on PornHub, but haven't ventured there yet...

That looks like fun MYTURN MY TURN YEA

Two girls go down the slide with a cake on the version on Pornhub. It's only brief and there's not much coverage though.

Uncencored version is even more fun:

Has anyone tried their lube? I'm thinking about buying it, is $19 too much for an 8oz/230ml bottle?

Get me there now I want to play
