This series of facial reaction shots showing Kenzie Vaughn’s enjoyment of some rough bondage sex at Sex And Submission demonstrate the sexual value of owning a good solid iron bed:

It’s a very demure bondage photo. Boring, even, until you think about the physics of her tied knees and those bricks under her heels. She’s going to find it very hard to move those bare feet when the caning of them starts:

Oh, this should be fun. Here’s Dave talking about hacking the Mattel Mindflex toy (which normally lets you control the height of a ball floating on a column of air) to get at the surprisingly detailed brainwave data, which can then be piped through an Arduino or another computer of your choice and used to control a vibrator (pleasure) or e-stim device (pleasure or pain depending on settings). He seems confident that the device can usefully detect arousal levels (impending orgasm) and thresholds of discomfort, which opens up the possibility of all kinds of fun predicament bondage, teasing and orgasm denial, or repeated forced-orgasm games.
There’s no unusually interesting ropework here – we’re aiming for immobilisation and sensory deprivation, but other than that, the restraints used don’t take an active part in the scenario. Sensory deprivation is important for the thing that is interesting here – keeping the EEG feed from the NeuroSky chipset in the MindFlex headset as clean as possible. Or, more usefully, NeuroSky’s newly-released elasticated MindBand headset with Bluetooth transmitter, which sends more data than the hacked MindFlex headset – all the way down to raw, non-FFT’d EEG readings.
Once that data has hit a processing system – something like an Arduino (limited capabilities, very cheap, tiny), a Raspberry Pi (flexible, cheap, small), or a full-blown Bluetooth-equipped desktop or laptop computer (extremely flexible, expensive, bulky) – the data can be processed and the vibrator and e-stim state can be set based on the submissive/bottom’s brain activity.
The scenario can be thought of as a loop. The vibrator and e-stim start in the ‘off’ state, and the EEG processor begins monitoring brain activity before the loop starts.
- Vibrator switches to ‘on’ state.
- EEG processor detects change of brain activity representing near-orgasm.
- Vibrator switches to ‘off’ state.
- System pauses for five seconds.
- E-stim switches to ‘on’ state.
- EEG processor detects change of brain activity representing a threshold of discomfort.
- E-stim switches to ‘off’ state.
- System pauses for five seconds.
- Loop repeats from the start.
This could, in theory, continue indefinitely. A control could be added for the dom/top to allow the vibrator to continue to stimulate the sub/bottom to orgasm at the end of the scene – or even a setting for one cycle in ten (or one in any number of cycles, or even a weighted or unweighted random number of cycles) to allow orgasm to be reached, after which the cycle could repeat yet again.
Me, I think the most obvious use of this technology is to control a number of stimulus devices and vary their inputs while monitoring arousal level to whatever extent possible. By closing the feedback loop and giving the computer a way to estimate the subject’s arousal state at all times, we enable machine-mediated trial-and-error routines to quickly determine stimulus regimes that work best under current conditions to achieve whatever your goal is, whether it’s fast hard orgasms or perpetual brink-of-orgasm teasing. In short, this is the first step toward highly satisfying sex-bots as well as diabolical mad-scientist sexual-torment machines.

Hmm, I could have so much fun with this setup!
All I know about this image is that it may be a screen capture from a video clip that was making the rounds of dodgy files-locker sites a few months ago under the title “4 Girls Falaka”.

Supposedly this is a traditional method for administering Chinese judicial corporal punishment:
I found it on an adult Tumblr, but it hardly seems worth linking to those any more now that Tumblr has sold out to Yahoo and locked all the porn away out of sight of the open web.

“Orgasming on command” is a common BDSM fantasy and (judging from what I read on the internets) a fairly common play project as well. How well it is reported to actually work varies a lot, with enthusiasts and skeptics both reporting in whenever this comes up in conversation. I like what This Girl has to say on the subject, and I’ve added my own bold emphasis on what strikes me as the smartest part of it:
This girl can’t remember when exactly, but Grimly built a brainwashing mask maybe about six years ago now. He designed it especially with her in mind because part of her still held back, part of her wanted to be controlled but the sort of headstrong independent part of her character was needing to be conquered, to submit because she had no choice that it was the natural version of events, because of his cunning, strength, dominance, ability, and basically him being an evil brainwashing bastard.
Grimly used a combination of the mask, electrotherapy and neuro linguistic programming to put a trigger in this girl’s head that whenever she heard a certain word (later a few different words) that she would orgasm and that she wouldn’t orgasm otherwise. This meant that even over the phone, just from hearing his voice this girl could orgasm.
Some people might not believe this, or might say that its faked. The thing is though, you believe what you want to believe. For most of the last seven or so years this girl has believed it to the point where she *has* orgasmed from his commands, more intensely from play and pain than from not, but even from cold she has orgasmed from his trigger word.

One of the many challenges of life as a chained-pet slavegirl is that sometimes master leaves you alone with your bowl of crunchies for two or three days while he plays with his new toys:
And there isn’t a lot you can do but watch quietly (if you know what’s good for you) and crunch your kibble in a jealous fury.
