I've lost some stuff lately, and I'm looking for a particular comic by Lapiness.

They've switched sites months ago, and this is the only thing they kept from their old site. The comic I'm looking for depicts two girls with one having huge boobs, and they're both tied up with tubes running from the girl with the big boobs to the other girl's behind. Inflation insues. I can't find it anywhere.
