It's getting a little ridiculous with the "Let's see how many dicks we can cram into this girl at once" thing. Sure, you have three dicks in her ass at once but none of them can really fuck and most of the contact is with the other dicks.
I'm reminded of a South Park episode where they said the word "shit" and it was kind of a big deal. On the episode, a TV executive decided that they'd say shit on one of their hit shows in order to cause some buzz. It was a big hit so in the next board meeting he decides that on the next show they'll say "shit" twice. Then that was a big hit so he decides that on the next show they'll say "shit" three times.
That's kind of what we have here. It used to be a big deal for a girl to just take one dick in the ass. Then they came up with the double anal. Now they're up to three dicks. I wouldn't be surprised if there's already a scene out there with 4 dicks in the ass.
When does it end?
