An odd little amateurish fetish video that will rent like crazy, thanks to the title. This tape features five naturally busty broads -- the blacks much better-looking than the white plumpers -- slamming their big, floppy zeppelins around like Muhammad Ali working twin speed bags. Come mild rope-and-stick boob compression and bondage spices up the aerobics routine a bit; but the attempt mostly serves to illustrate that it's not easy to tie up your own tits.
