Huge tits girl tortured on a bdsm machine

The horny kink has invented a real bdsm machine and now he is trying it in use with the gorgeous big boobs bimbo. He is enchaining her in the doggy style position. Her enormous titties are tied tightly, she's got pomps on the big nipples that are aimed to reach some milk out. Her big butt is lifted highly up into the air, the legs are stretched uncovering the view on both pussy and ass slits.
