It should be obvious - scenes with multiple girls are increasingly expensive, and clearly aren't making any profit - otherwise studios would be pumping them out left, right and centre. The one great scene we could rely on was the Gonzo Xxxmas scene, but now that studio has gone under, is anyone else going to pick up this baton? I hope so, but I wouldn't be surprised if that's the last we see of this type of scene. Heck - several years ago, it was feasible for companies to film reverse gangbangs with 10, 15 or more girls - now this entire genre is pretty much extinct.
