Brooke Johnson Extreme Torment And Pleasure
Cast: The Pope, Brooke Johnson
Description: Brooke Johnson is back and ready for another round of extreme torment from The Pope on Device Bondage. She is excited to push and test the limits of how much pain she can endure. Brooke's session begins with cold steel wrapped around her neck, wrists and ankles keeping her locked in a spread-open sitting position. The Pope warms up her exposed flesh with hard smacks from a riding crop, immediately causing Brook's pussy to get wet. A plethora of electro-toys are used on the pain-slut, and Brooke can't help but smile as she suffers from shock after shock all over her sexy body. Her obedience and willingness to suffer is rewarded with delicious, coerced orgasms that have her screaming and squirming in her bondage. In the next position, Brooke is gagged and standing with her arms secured to the ceiling behind her in full leather restraints. Her legs have a sadistic spreader in between them that has sharp points at either end poking into her tender skin. The Pope brutally flogs and canes Brooke's backside in the strict position as she shakes intensely from the torment. More orgasms are ripped from Brooke as she loves the pleasure of the pain. In the final position, Brooke is laid on her back with her wrists locked and legs spread in steel traps. Her marked-up thighs are brutalized with another round of ruthless caning before she is given more orgasms while being fucked with the dick-on-a-stick.

Anya Olsen, Phoenix Marie. Anal MILF Phoenix Marie Trains Lazy Daughter-in
Cast: Anya Olsen, Phoenix Marie
Description: Phoenix Marie is a high protocol anal submissive grand dame you would not want to cross, but self absorbed little slut Anya Olson has no idea what kind of family she has just married into. Petite, gorgeous, and in need of a spanking, Anya attempts to drive a wedge between Xander and his step-mother, but some ties cannot be broken. Phoenix has long been in service to Xander, offering all her holes and care taking the family mansion: It is high time Anya be initiated into a sexual slave lifestyle under Phoenix' perfect round ass.ÂXander begins Anya's training after a particularly bratty episode, using his belt to beat her ass and control her head for a hot sloppy blowjob. Once she has a swollen red butt and her sir's and thank you's down, she is strapped down to the bed in tight belt bondage, fucked mercilessly, and shocked while begging to cum.ÂPhoenix will not be comforted, and continues to insist that Anya is untrainable. Xander puts her back under his foot, allowing her only to complain about his wife with his thick cock wedged deep in her throat or with an electric plug deep in her ass. With her huge tits clamped and her step-son pounding her swollen pussy, Phoenix promises to train Anya.The rest of the day is spent turning this pretty little newly wed brat into a humbled fuck toy, begging Mommy for all of her orgasms and thanking her husband properly for every stroke. Crops, rope bondage, zappers, and verbal humiliation are just the beginning for Anya. The true degradation is learning she must lick her husband's cock as he fuck's his step-mother's ass before she can earn any of her own fucking. And if she squirts without permission, Phoenix will be there to punish her with an iron fist.Â

Gal Ritchie Predicament Bondage, Torment, and Suffering Makes for a Happy Gal
Cast: Gal Ritchie, The Pope
Description: Gal Ritchie is brand spanking new, and has set so many things in motion to be right in this place, and exactly at this time. She knew she wanted to shoot for Kink.com, and put her head down and did the work that it took to get her here. Well, she's here, so what is she going to do now; suffer that's what. Gal starts in a predicament sitting position and held in place with a web of hemp rope that prevents her from moving at all. She doesn't know what her ability is yet, since this is her first time, so The Pope gets to work finding out what makes this slut scream and moan. Nipple clamps are added, and Gal does not even flinch, so meaner clamps are added to her nipples
and then weights. She is suddenly very timid and quiet, so clover clamps are applied to her outer labia, and weights are added to that as well. orgasms are what's going to crack this nut, or so he thinks, but Gal is not going to give up anything without The Pope taking it from her. Next, Gal is put in a brutal tie that has all of her body weight hanging from a few wraps around her waist. The rope is positioned with the intent of making her suffer, so it is placed above her hip bones. Her ankles and wrists are pulled one way, and her neck is pulled the other. Orgasms are what have gotten the best reaction out of her so far, so we begin there to loosen her up. The crop hits some of the sensitive areas before using a dildo to fuck her throat and pussy to get some squirting orgasms. In the final position, Gal is bent over a sodden horse and stretched out. She is flogged and vibed until her eyes roll back into her head. Gal is going to need more work to get her to open up fully for us, and The Pope has already made plans to bring her back for round 2.
