MetalBondage - Katarina Hartlova - Wrists to boobs (2022/FullHD/527 MB)

Surely 2 boobs cuffs will fit on each of Katarina's huge natural boobs? We cuffed her boobs with 1 cuff each before, but two makes it more secure. Katerina in a chastity belt, boob cuffed, wearing a heavy collar, that's something you don't want to miss. To make this a bit harder for her, we cuffed her left wrist to her right boob and her right wrist to her left boob! Behind her back! With double handcuffs of course. Then we gave her the key and watched her struggle, those giant natural breasts swinging as she tried to reach the keyholes. We love Katerina. She should be in bondage permanently. Especially her boobs. Did we mention boobs?
BeltBound - Katarina Hartlova - Strapped in leather (2022/FullHD/376 MB)

When someone like Katarina comes to the studio, we can't go easy on her! It's Katarina Hartlova! Best natural boobs and a true struggle lover! We strapped those huge breasts with locked belts, and got her into a leather body harness and thick leather collar. Arms neatly tucked away in an armbag, and legs frogtied, Katarina started to get a bit worried. She struggled and protested, but that was quickly solved by adding a nice tight harness ballgag! Yes, Katarina sure got the full packages. she deserves it!
BeltBound - Katarina Hartlova - bolero perfection (2022/FullHD/374 MB)

We love bolero straitjackets! They leave a girl so exposed, in ALL areas. But for maximum effect, big boobs help to make these jackets look even more spectacular. And there is no better test subject than the famous Katarina Hartlova to do some great struggling in a bolero jacket. Her huge natural boobs are completely unprotected as her arms are strapped around her body. A nice red ballgag stops her from protesting. She is still pretty dangerous though, watch those high heels! Please wait till she is tired before approaching her!
Hucows - Katarina Hartlova - Maximum Power Test (2020/FullHD/791 MB)

300 updates! Wow, we have actually grown so quick as a ranch for the past five years! Time to commemorate with a special upgrade of among our most preferred HuCows: Katarina! She is just amazing, with her significant all-natural udders and also slim body. Katarina is quite crazy though, so she needs lots of chains constantly or we can't bleed her. In this update, we ran the red cow milker at maximum power. It was a test to see if Katarina could take it, and also she did quite well. We also wanted to enhance the rate at the end but Katarina was not ready for that yet. A substantial crawler trick made sure she might just make moo noises while she was strapped to the bleeding bench. A wonderful position to commemorate our 300th! Hopefully we can entertain you with at least 300 more! A huge thanks to everyone who has actually supported this website thus far!!
ShockChallange - Katarina Hartlova - Challenge failed (2020/FullHD/343 MB)

We caught Katarina after she was finished shooting for www.hucows.com, and we asked her if she was interested in a little challenge. We started by a bit of shocking to the SIDE of her neck. The electro contacts are actually on the muscles so we could make her head jerk to the side which was really funny. Katarina did not think it was funny at all. She started getting angry with us, so we changed the position of the shock collar – to her boobs! Yes we locked 2 shock collars onto her boobs! Unfortunately, Katarina got even more angry with us, and decided to walked out of the challenge. She did not make it and she did not get her prize. Oh well. it was fun anyway.
