Video language: English
Maya Woulfe has been on a journey, exploring the boundaries and uncharted regions of sex and intimacy through her experiences as a sub. As she fills a bathtub with steaming water and gets out of her robes, she recalls some of the rules she follows so that her dom is always satisfied.
She will make her body available for her dom to use at any time. She will anticipate her dom's needs before her dom needs to ask for them. She will thank her dom for every orgasm her dom allows her to have. And, lastly, she will keep her body clean and groomed for her dom's pleasure.
But today, Maya has chosen to switch things up. For once, like to be the one who sets the rules, so she's enlisted the help of Leana Lovings to be her sub. What kind of dom will Maya be? Will she be confident and stern... or affirming and fair? There's only way to find out... by taking the power for herself.

'Hi, I'm Lauren Phillips, and I am super excited to introduce you to my new project, 'Switch: Embodiment.'
'I really wanted to show the switch of a female and how you don't have to be just submissive or just dominant -- that you can actually be . You can have a power exchange depending on the person you're with in the scenario. I also wanted to introduce BDSM that's more on the lighter side to hopefully cast you in.
'I really hope that you comment. Give me your opinions, give me your advice. Tell me what you want to see so that you can fuel my creativity because, at the end of the day, I just want you guys to enjoy what you're watching... and get off on it!'
One day, Victoria Voxxx finds an erotic book and steals it away out of curiosity. As she reads it, she becomes enraptured by the BDSM nature of it and how intensely the submissive woman within its pages experiences raw pleasure. Victoria finds herself endlessly daydreaming about what that would feel like, which starts to affect her everyday life and eventually leads to her seeking therapy.
Victoria is bashful when she meets Dr. Casey Calvert. They begin discussing Victoria's fantasies and Dr. Calvert quickly realizes that, as a licensed kink-aware therapist and sex surrogate, she can help Victoria live out these secret desires.
Victoria is shocked but intrigued as she mumbles, 'I would like to... but I wouldn't know where to start.'
That's when Dr. Calvert stands up and takes Victoria's chin in her hands. 'The dominant always knows where to begin!' she says in a stern tone. 'You just do as I say, do you understand?'
Victoria nods, her lips quivering as her body instantly burns hot with arousal.

Let It Out - Elise Graves and Lita Lecherous - HD 720p
I love playing with switches so much! (a switch is someone who enjoys both the top and bottom role in a BDSM scene) Lita Lecherous is a wonderfully sexy switch who is in top position over me in this scene, and I love it. She binds me to a tilting medical table with medical restraints. I am gagged with a metal dental gag at first and a large ball gag further into the scene. Then Lita connects nipple clamp electrodes to my breasts and fucks me with an electrical dildo while vibrating my clit and making my brain explode!

Blondies Punishment
Video language: English
When my blonde slave gets out of hand I bind her body in rope as punishment for her disobedient ways. I also greatly enjoy using my switch to taunt my blonde slaves bound tits. I also enjoy lobbing tennis balls at her nipples from the side. They sting without doing any real damage. But using a switch or a cane on her nipples usually suits me best. I love to punish those protrusive nipples of hers because it is not only painful but humiliating for her to be drubbed on the very part of her that is most emblematic of her womanhood.

Cute blonde Skye Blue takes the lead in this fascinating glimpse behind the scenes on a SexArt production. As director Andrej Lupin calls action on 'Your Choice,' stunning Skye -- aided by producer Ariel Piper Fawn -- invites social media followers to pick what positions they would like to see her in. Maxmilian Dior watches enthusiastically as the responses roll in, contributing his own suggestions, eager to get intimate with this gorgeous girl. They begin with Max squeezing and sucking Skye's beautiful breasts as she grinds in his lap, before she turns around into the first requested position, reverse cowgirl. Guiding his stiff cock into her shaved pussy, she slides up and down on it, rocking her hips to take it deeper, breasts bouncing alluringly. Max strokes Skye's clit as she rides to a powerful orgasm, then dismounts and kneels to suck her juice from his thick shaft, and jerk it between her big boobs. They switch positions so Max can kiss his way down to Skye's pussy, fingering and eating her avidly, then thrusting back inside her in missionary. He fucks her energetically, picking her up still impaled on his cock and carrying her to the bed, where they try the scissors position requested, but soon switch to doggie so they can go wild. Face down ass up, Skye encourages Max to plow into her vigorously. Finally, they switch to cowgirl, Skye riding to another climax and a hot creampie that gushes out as they uncouple.
