E-Stim Systems Black Collection

The E-Stim System Black Collection Bi-Polar Butt Plugs

Vendor: E-Stim Systems

2 ½ years ago E-Stim System introduced their Red Collection, a more “sculptural” approach to their popular (and by me highly praised) bi-polar electrodes. While I liked the shape of the electrodes, the design with red velvet colored isolators and mirror-shine finished poles did not really appeal to the “rough” look I like in my toys and playroom. Also, the sizes were quite “Lady-like”. Naturally I was excited when they turned their Bobble into the Black Collection.

Construction

The basic design are two beads stuck onto each other. They are separated by a black plastic neck which serves as an isolator between the two poles. At the bottom the lower bead tapers into a base which has the same diameter as the beads. Around the base run three (resp. four on the XL) groves for better grip even with lubey fingers. Into the base’s bottom a 4mm hole to plug in 4mm banana plugs is drilled. The plugs are available in four sizes.

Detail of the Satin Finish

The upper bead is connected the lower part by a stainless steel screw. At its bottom there is a 4mm hole to connect the upper pole to the power box using 4mm banana plugs. To not short-circuit the e-stim box, the screw-head is isolated with a white plastic separator from the base. Around the banana plug socket these is a little hexagonal socket for easier disassembly when cleaning. This socket is highly useful because the screw is harder than the aluminum the electrode is made out off so it will dig into the material. I have older electrodes which do not have this socket and which have become almost un-screwable.

Like all premium bi-polar electrodes the Black Collection is made out of aircraft grade aluminum which is perfectly finished in E-Stim System’s satin matt finish. Since I have already gotten some reader questions about this topic I want to stress that the toys are indeed silver colored and not like in the promotion pictures black.

Playing with the Black Collection

For basic information on how the bi-polar electrodes perform and how to choose the right size, please check out one the review of other models I have published some time ago. Here I want to talk about how the interesting design produces unique sensations.

The Bi-Polar Plug Disassembled for Cleaning

What sets the Black Collection apart from all other bi-polar anal electrodes I have seen so far is that the split between the two poles is at the top instead of the bottom. So when lying down you can choose either choose between pushing it in all the way to the second neck or let the sphincter wrap around the isolator on the first neck. In this position all stimulation is focused on the sphincter, just like with the Micro. But through the larger mass and surface area the sensation is smoother.  Since the mass center unlike the other electrodes is on the outside the sensation feels… in lack of better words inverted. This is especially interesting when a wave program is used for a fucking sensation. It is still a fucking but with a new, different twist.

When sitting, standing or walking the electrode should be pushed in all the way. Especially when not sitting, the mass center outside the body will make it very likely that the electrode will fall out of the ass otherwise. Pushed in all the way, the sensation moves from the sphincter inside the body. This is a weird feeling, because the stimulation feels like a big, massive surface electrode but isn’t experienced on the skin. Again, it is hard to describe, but it adds a new sensation to the e-stim repertoire.

Especially the two largest electrodes have enough weight to develop an own movement momentum when the sub’s body moves, for example through walking or making him jump from the stimulation inside him. Depending on the rectum’s physiology the electrode will start to tumble, adding a physical sensation to the fact that electro stimulation flashes up on different areas on the bowel mucosa. Depending on the sub’s anatomy, the upper bead can lay on top of the prostate. So just like when a Classic hits the prostate, only using the upper pole in combination with a pad electrode attached to the perineum above the prostate is an interesting way of tormenting this sensible body part. Some subs can even be trained to get milked that way.

Finally, let’s take a look o how the Black Collection’s plugs perform just as anal toys without added e-stim. While they are fun to ride for more experienced anal players, they are good for training new fistees. Slowly fucking the hole with the two beads will teach the hole to open up and close again, even when the entering object is relatively dull. The beads are also perfectly designed to stimulate the prostate; one testee even developed a technique to how to thrust and twist the plugs just right to prostate-milk his chastity sub.
