8 XXX : bdsm

Ugh how much I want to be locked in a cage overnight with a pair of vibrating panties set on high. I would be begging for mercy in a hour.
I mean... it's hot and all, but other than the cage that's in maybe 1/3 of the gif, what makes this any different from vanilla porn? I've been noticing that a lot lately on this sub. Vanilla porn with one or two basic and not too-uncomfortable sex toys thrown in so it technically counts as BDSM. It's not really what I subbed to see.
source?
