When I saw the title of this site, I thought Oprah had expanded her gigantic media empire into the porn industry. Thankfully, I was mistaken. The sitename TheTrainingOfO is a reference to a famous S/M flick that I had momentarily forgotten. This website has picked up on the theme of the movie and dedicated itself to the training of loyal female slaves by a hardcore Master.
The site is laid out well and you won't have any trouble finding all 155 episodes. Each comes with a video and photo. More content is being added on a weekly basis and that's impressive, because each shoot takes several days. You really see these ladies being broken down as they film themselves off the set describing how they're coping with the intense training.
The 155 videos are all downloadable and come in a variety of formats and qualities, so you can choose the option that suits both your viewing needs and your download capacity. You will always find a version with high-def playback and some files will work with iPhones or other mobile devices.
The training sequences are also documented by the extensive 155 photo galleries that present the scenes frame-by-frame in high-res pics. The galleries are also accompanied by explanatory write-ups that help provide a context and make for a great overall experience.
The various scenes involve all sorts of training from lessons on how to maintain discipline under torture as well as detailed instructions on how to suck cock, eat pussy or show off for the camera while getting pounded. They will definitely satisfy anyone into BDSM training, even if sometimes you actually see a model who's so physically and mentally exhausted by the ordeal that she gives up and quits.
There is a link to extra behind-the-scenes action, but there are no bonus sites to be seen. You will also find a members' forum. Feedback on each episode is possible through a comments section that appears below each scene. This impressively produced site is definitely worth joining.
