I didn't see a group for this...and it seem that some people on Cerb like bdsm ( Bondage-Discipline, domination-submission, sado-masochism). Here is a little place to post bdsm pictures, erotica or whatever. :)
Don't get me wrong, I love all boobs, but there is just something about big knockers that makes you go MMMM! If you think more than a handful is a waste, then this isn't your place...
