So, at first, they released the first vid at a stupid price. Then they say that if you buy it, you will get the strap-on vid for free.
Soon after, there is a message that you can buy it cheaper for 125usd, but you won't get the strap-on vid.
And in the end, they didnt apparently make enough from it to do the strap-on, so everyone who bought it with the hope of getting the second for free must be quite pissed.
And on top of that, according to this post, they were both uncomfortable doing it, so I must ask, why did they even shoot it then, if they both basically didn't want to?
Dont tell me because the fans wanted it, because if that were the reason, the price wouldn't be as much as for 10 normal vids.
