During Mistress Miranda's last visit, she was invited to tour the headquarters of the popular on-line retailer Extreme Restraints in Los Angeles. Extreme Restraints is one of the largest suppliers of bondage and kinky products in the world.
During her visit, Miranda was invited to present an XR University video lesson with some of Extreme's leather bondage gear, which she demonstrated on the popular bondage model Casey Calvert. This video is the result, and as you will see, they had a lot of fun subjecting Casey to Mistress Miranda's kinky bondage methods. Naturally, Casey's torment was inflicted for strictly educational purposes!
A special thanks to Ian Rath, Aiden Starr, Mistress Miranda, Casey Calvert and Extreme Restraints for sharing this sexy and ‘highly educational’ video with us.

In the fourth part of our interview series with Chris from Steelwerks chastity, we watch as a few pieces of his gear are demonstrated by a pair of adventurous and kinky women. These pieces include two labia spreaders and a sexy red butt plug. This Steelwerks gear is like expensive jewelry and is quite erotic and mesmerizing when applied to the intimate female genitals. During this video a fun and sexy banter is heard between Chris and his female participants. If you are considering the purchase of any Steelwerks gear, review our entire series for valuable points to consider before ordering.

First Time Bondage Research

http://t1.smplace.com/preview?/thumbs/2601/13354751_firsttimebondageresearch.jpg http://t1.smplace.com/preview?/thumbs/2601/13354752_firsttimebondageresearch_thumb.jpg

SBI is always ready to help when there is an educational need. We had a "student" who was doing "research" and want us to tie her up. I've heard and used plenty of lines to tie or get tied up myself, but this one was original enough we couldn't refuse. One thing I knew was she was curious and willing for whatever reason. I took a teaching approach to our session. I explained what effect I was trying to achieve in each bondage scenario. Compression, sensory deprivation, and total immobility, in a sleepsack, a strait jacket, the famous bondage chair, a vulnerable chair tie, and finally mummification in a coffin. Everything was explained and executed then she was debriefed as to how she felt. What surprised her the most was how much it stirred her sexually. I hope she can find a way to put that in her "paper". This was so much fun for us all, I learned a great deal myself.

Goodbye Bondage Roadtrip - Getting Ready

http://t1.smplace.com/preview?/thumbs/2601/13355146_goodbyebondageroadtrippart1.jpg http://t1.smplace.com/preview?/thumbs/2601/13355147_goodbyebondageroadtrippart1_thumb.jpg

SBI is always ready for some outrageous bondage. Our intern is moving and we have fiberglass and a van. Well, it isn't that simple there have been many fiberglass encasements but we had no idea how much our intern wanted to experience it. This time we chose a more traditional position, if there is such a thing as traditional bondage position. First layer was cotton which created a padded mummification for protection. Second was the usual pallet wrap and duct tape. Third was a very thick layer of medical fiberglass. We than positioned our cargo on a wheel around cart. This process took some time. The hours before we loaded up were spent in silent darkness.

Left To Suffer

http://t1.smplace.com/preview?/thumbs/2602/13357151_lefttosuffer-r438.jpg http://t1.smplace.com/preview?/thumbs/2602/13357152_lefttosuffer-r438_thumb.jpg

Although I discourage self-bondage, the chair features self-retracting and locking mechanisms behind each wrist strap. Pulling on either of two small chains releases the wrist straps independently so if one gets stuck I could still release myself with the other. There was no time release system involved, I could release myself at any time. Time release bondage is MUCH too dangerous, as I have found out first hand with two life threatening experiences.

Yours 4 Ever

http://t1.smplace.com/preview?/thumbs/2602/13357659_yours4ever-r407.jpg http://t1.smplace.com/preview?/thumbs/2602/13357660_yours4ever-r407_thumb.jpg

This is a sexy video featuring our intern 'petgirl_kako' (onFetLife). Petgirl writes a note to her lover who is expected home any minute, then locks herself into spread-eagle bondage as a special surprise gift. This is a common fantasy which many bondage people dream about.
We do not encourage self-bondage because the dangers are far too great. We present this video for entertainment purposes only, and not as a guide to self-bondage. So, enjoy this video and the excitement you feel when Petgirl cinches up the straps and clicks the locks to ensure her helplessness. In real life, self-bondage is an extremely dangerous activity. If you play with self-bondage do so at your own risk.

Endza - Unauthorized Climax

http://t1.smplace.com/preview?/thumbs/2602/13358300_endza-unauthorizedclimax.jpg http://t1.smplace.com/preview?/thumbs/2602/13358301_endza-unauthorizedclimax_thumb.jpg

Endza should know better than to cum without permission. OT shouldn't have to tell her that things like that are unacceptable. She's shackled down, with her ass in the air. She just suffered a brutal caning. Her clit is clamped with weights. It should be obvious that she is the submissive slut, and a good submissive slut knows that she has to beg for permission, and wait until she receives it, before having an orgasm.
She'll learn the lesson, though. The caning was just for fun, the whipping will be for punishment. One foot on the floor and the other strung high into the air, Endza's pussy isn't just exposed, it is practically a painted target. It's begging to be snapped at with the whip. And after a few minutes of sharp stinging across her sensitive clit, Endza will be ready to do some begging of her own.

Mistress Miranda - Gas Mask Playtime

http://t1.smplace.com/preview?/thumbs/2603/13358851_mirandadixongasmaskplay.jpg
http://t1.smplace.com/preview?/thumbs/2603/13358852_mirandadixongasmaskplay_thumb.jpg http://t1.smplace.com/preview?/thumbs/2603/13358853_mirandadixongasmaskplay-2_thumb.jpg

In this video our friend Mistress Miranda takes delight in tormenting the popular bondage model Dixon Mason. This is the first time Dixon has visited the sbi, and we are honored to have her in our presence - and restrained in our gear! Just like Miranda, Dixon is a classic gear-head and bondage slut, so so she feels right at home in our facility. Note: the skin-tight ballet boots that Dixon is wearing in this video are on loan to us from the 'TheEvilOne' on FetLife, are worth seeing even if you are not a boot lover. Additionally, the bondage strap set used to restrain Dixon is a relatively new product from Maxcita in Canada and we reccomend it highly. Miranda and Dixon have good chemistry together, and we look forward to seeing them at the Instutute on a regular bassis.

PD and his IR - Part 5

http://t1.smplace.com/preview?/thumbs/2603/13359424_pd-interview-part-3of4-s833.jpg
http://t1.smplace.com/preview?/thumbs/2603/13359425_pd-interview-part-3of4-s833_thumb.jpg http://t1.smplace.com/preview?/thumbs/2603/13359426_pd-interview-part-4of4-s833_thumb.jpg

In part-two of this two-part update, the creator of the notorious IS ‘PD' is interviewed by our friend JG-Leathers. PD's well known IS was the most popular and extreme BDSM site in the early 2000's, as it forged a path in the early days of extreme bondage on the Web. IS attracted thousands of members before it was shut down under US government pressure. During this interview PD talks about his childhood, exposure to bondage in Japan during his days in the Navy, teaching background, and the realities of running IS.
This update is part of a series of interviews and behind-the-scenes visits we filmed with PD in his new studio located near San Francisco. If you are a fan of custom bondage gear and eye-popping BDSM scenarios, you will find these interviews to be extremely interesting.
