Serious Kit – Electrically Engineered

The past spring we had a chance to meet the proprietor of Serious Kit along with several hours to get a look at some of their gear in person. The bespoke company’s focus is, as you could imagine, on serious kit – specifically milking apparatuses. While not their sole item, the majority of the product offering is geared for cocks (though a breast variant is also available).


Perverts turned entrepreneurs bring something special to their products, including ensuring their gear meets their own stringent demands. This could mean years of tinkering with a design, exhaustive quality assurance (tough job!), and of course, stressing over all the little details. This common story is very much true of the SK line, where “our kit is designed by fetishists, not accountants”.


The craftsmanship speaks for itself – a clear departure from the established products (Venus 2000) with a modern, clean design (in fact, bondage furniture was a predecessor business). Each order is handcrafted in the UK, with numerous options; avoiding the “off the rack” factory aspect. The colored tubes indicate flow direction, critical for extended play with the lubrication reservoir. Refurbished milkers receive a beautiful chrome polish. The milkers can be used simply as milkers, or they can have e-stim electrodes integrated as well, depending on the particular model.


We particularly liked the design of the bi and tripolar stainless steel rings for e-stim play. This paired with a butt plug electrode (such as Mr. S Leather’s WMCBP or E-Stim Systems Torpedo) would be sensory overload in the best way possible – bound to produce a “HFO” or hands-free orgasm.

B and I are both fans of multi-hour long sessions, where the bondage turns into a therapeutic escape from everyday stress. Many would call this entering headspace, or focusing so heavily on the experience that all distractions melt away. SK summarized his own experiences in this realm as “It’s about the fun and pleasure… the pleasure that comes from pain”. Professional doms know this all too well, where competing purely on an exhaustive toy collection isn’t enough. Controlling a session, where sensations can be precisely adjusted is one of the primary advantages of the Serious Kit. The design allows for many different knobs to be turned, lending itself to the ability of producing multiple unique sessions using the same equipment.


Though their main focus is intense genital stimulation with the milking machine, Serious Kit has begun to also offer an encompassing full body “neural novel stimulation” experience: the vac suit. The “vac suit” is essentially “a vac bed on acid” – based on a loose catsuit pattern, coupled with the milking machine, and retained vac bed-like suction. The suit is made of chlorinated rubber, both glued and sewn together, and designed as a “one size fits all”. My favorite story gem is “Germans love our suit for watersports, where the milker can suck away {all the mess}!”.

It was truly a pleasure to geek out at Serious Kit headquarters, and we greatly appreciate SK taking the time to show off their kit and talk shop with us. And, personally, I’m certainly hoping Santa can deliver me a HFO for the holidays this year!


Despite being exhausted after a long day of travel, we finally got around to testing a new toy out earlier this week when I found a horny M all ready to go in his spandex, the leather sleepsack, and a latex mask when I came to bed.

I quickly zipped him up. Digging around in our kinky travel case, I finally found what I was after: the Zap electro ball stretcher by Oxballs.

M had purchased the Zap sometime in the past month or two, along with a new set of rubber mittens (and a locking rubber penis prison, which will be reviewed soon!), from Los Angeles based Stockroom. We hadn’t had a chance to try it, however, so this seemed like the perfect opportunity to test it. I quickly wiped it clean (we had been showing it off to kinky friends during our trip) and pulled out the electro gel. M also confirmed at this time that his hands were free — something that I had to remedy with those new rubber mittens he had purchased.

Unzipping the lower part of the sleepsack encasing M, I realized he had already put two Oxballs Screwballs on — one around both his cock and balls, and the second around just his balls.

It’s important to note that the Zap is similar to 2 Screwballs stacked on top of each other, meaning it does give a nice stretch… but it also makes it more difficult to put on. Deciding to leave the Screwballs on M for now, I added both metal contacts to the toy (it can be used as a single pole as well), a liberal amount of electro gel to both it and him, and just slid the Zap down his cock. I then zipped up the sleepsack around him, but leaving him exposed.

I pulled out our 2B box and plugged him in. After a bit of a false start (problem with the cables), I finally had him beginning to moan and whimper and thrust. I eventually switched the e-stim box to my favorite mode, Training, and increased the power as much as he could stand it.

The interesting thing about the sleepsack, the Zap, and M’s thrusting is that it ended up being extra mean. The Zap would catch on the zipper of the sleepsack with each thrust, pushing it and M’s skin up and down his cock while the e-stim continued. Eventually exhaustion began to overwhelm me despite enjoying the torture session and considering my options, I added some silicone lube to the tip of his cock before wrapping my hand and mouth around him.

Now M describes the experience as “intense… both pleasurable and painful.” At the time, though, all he could do between the whimpers of pleasure was choke out “you’re so mean” and “that feels so good.”

So, despite not using the Zap exactly as originally intended, I think we’ll be using it a lot more now that we’ve given it a try. It was harder for him to get off in the end, but ultimately it seems like it was a much more intense orgasm as a result. That’s an obvious win by our measurements.

Review + Hack: Oxballs Sacksling

I don’t entirely remember where we discovered the Oxballs brand, likely from a stroll at Mr. S or a horny 2am Fort Troff shopping binge. Their designs are quite unique and I’m told much of the early products were made within the US.

One product in particular caught our kinky interest – the Sacksling “electro” edition. Our unit has a frosted silicone material sack with two removable conductive “contact” points.Oxballs Slingsack closeup These are shaped as small circles, about the diameter of small denomination currency coins. The mating connection is a female 4mm banana plug. The intention of the product is to “zap up” some pain across the scrotal area on the flat ball facing side of the metal contacts. The design is perfect for rapid deployment, as being bi-polar means no searching for another body part to complete the circuit.

After a number of test runs, we discovered a major flaw – unless your balls are making solid direct contact, the e-stim can come across as very aggressive jolts (which may be the desired outcome for some masochists) instead of more soothing electro torture. This is especially relevant in non-standing positions, where gravity may not necessarily be on your side (again, choose your own adventure when it comes to electro torture). Conductive lube is critical for this application, sweat can easily build up in the sack – we use Spectra 360 gel.

As we fancy ourselves as geeky types, we ended up adding a layer of Sugru to narrow the distance between the sack and contacting balls. Oxballs Sacksling Sugru hackSugru is a rubber-cement like product, think of it as Play-doh for adults that’s designed to harden on purpose. It’s a very popular crafting tool in the maker scene, with the added benefit of being safe against body contact too! The hack is simple and effective enough to tone down the jolting.

One word of caution, the material of the sling is prone to rip easily and also doesn’t play well with other materials. We had one sling that had extreme discoloring only after a few months of infrequent use. Storing separate from other tools does appear to minimize the color changes.

Mr. S Leather

If you haven’t been to Mr. S Leather in San Francisco, CA, then you are seriously missing out. It is the biggest and baddest kink and fetish store around. While it largely caters to the gay male community, it still has plenty to please any pervert.

So, of course, whenever the opportunity arises, M and I stop by Mr. S.

M has been a customer for years, but he just introduced me to this wonderful (and admittedly, initially terrifying) store about a year ago. Oh the difference a year makes… No longer the shy girl out of her depth, M’s previous assessment of my reaction at The Stockroom in LA is appropriate even now: I was a kid in a candy store.

One of the truly great things about Mr. S is that the staff are incredibly helpful, incredibly knowledgable, and incredibly nice. On a prior trip to Mr. S when M had been considering a particular cockring, they encouraged us to go into the dressing room and “try it on”. If you have any questions — and I mean *any* — they will try to help, and often come up with great solutions to challenges or suggest the perfect product.

While the damage was not insignificant to my bank account, it could have easily been much worse. As anyone into kink and BDSM knows, it is typically not a cheap hobby. But it is a ridiculous amount of fun. And I finally own my own pair of fancy locking wrist restraints.

Dear M…

Regarding this, I suspect you already know the answer, but I will say “most of it”. Perhaps a different mask and/or gag (you probably know the ones I have in mind), but you already know how much I enjoy electrifying experiences and being tied up… ;)

Add this to the wishlist? – xoxo, B

In the Moment

M and I talk about writing stories. Recounting past exploits and imagining future ones. We send each other snippets of fantasies, and talk for hours about what we plan to do to each other. Or, even more dangerously, what we want done to us. They say the largest sex organ is the brain, and we certainly don’t ignore that.

It’s difficult, though, to remember the details. It’s hard to recall and put into words exactly what was happening the night before. So many of the details blur together, only a few very specific things standing out in stark relief.The thrill as he tightened the straps on my arms, pinning them behind my back. Closing the Kali’s Teeth around his hardening cock and snapping a lock on it. The sweat dripping onto my face as he fucked me on the floor. Brushing my hand over his tender nipples, captured by clover clamps. Begging for more, begging to be punished. There’s so much between these snapshots. Lust and fear and trust and the desire to push ourselves, and to push each other.

He comes home from another business trip, this one longer than anticipated. I’m dressed up and waiting for him, restraints ready, mask over my head, on my knees. The anticipation nearly kills me as I hear the key turn in the lock, waiting for him to set his bags down and shove his hard cock in my mouth.

Another night I replicate the “science experiments” I ran while he was away. But this time he restrains me and takes the control box, tweaking the settings, adjusting the speed and intensity of the electricity. In no time he has me begging for mercy.

I do the same to him another night. Zipped up tight in the sleep sack, chained to the bed. I take the box into the other room, playing with the settings to remind him I’m still there, giving him a jolt now and then. But I want to watch him, and I want to push his buttons, so I end up sitting on the floor by the bed, adjusting the settings, eventually making him come.

For a long time, neither of us felt the need to use our safewords. We had them, but rarely uttered them. Lately, though, it’s almost as if we’re daring the other to say it. Trying to push each other into crying “red”. It’s a boundary that we need to push, but we’re pushing it together.
