Sultry Sub

Sultry Sub

This is the wireless receiver that transforms any Mystim e-stim device into a remotely controlled experience. Connect it to your existing Mystim toy — whether it's an insertable probe, cock loop, or electro pads — and control the intensity and patterns from across the room using the Cluster Buster remote.

Sultry Sub receives the wireless signal from Cluster Buster and delivers the electrical impulses directly to your toy. You can use one receiver for solo control, or add multiple receivers (each set to a different channel from 1-8) to control several toys independently. Each unit responds only to its assigned channel, so you can stimulate different body parts with different patterns simultaneously — or hand control to a partner who decides what you feel and when.

This is particularly useful during bondage or power exchange scenarios where the person receiving stimulation has no control over intensity or timing. The range is sufficient for bedroom or playroom use, and the receiver is small enough to stay discreet during wear.

What's in the Kit

You receive one Sultry Sub receiver unit. It connects via the standard 2mm pin cable to any Mystim electro sex toy (sold separately). The receiver has a channel selector (1-8) and a connection port — nothing more. It's designed to be simple: set the channel, connect your toy, and let the Cluster Buster remote handle everything else.

Note that this receiver requires the Cluster Buster remote control to function — it has no standalone operation. If you're building a multi-toy setup, purchase one Sultry Sub for each toy you want to control independently, and assign each a different channel number.

How the Intensity Feels

The sensation depends entirely on which Mystim toy you connect and how you use the Cluster Buster remote. The receiver itself simply transmits the signal — it doesn't alter intensity or pattern. What changes is the control dynamic: instead of adjusting settings yourself, someone else (or a pre-programmed pattern on the remote) decides when the tingling starts, when it builds, and when it stops.

This removes your ability to anticipate or moderate the stimulation, which intensifies the psychological experience. A gentle pulse becomes more acute when you don't know if it will stay gentle or suddenly spike. The unpredictability is part of the appeal — and part of why clear communication with your partner about limits is essential before you begin.

Where You Can Use It

The receiver attaches to any Mystim e-stim toy, so your placement options depend on which accessory you connect. You can use it with insertable probes (vaginal or anal), cock rings and loops, nipple clamps, or electro pads for external body stimulation. The receiver unit itself clips to clothing or rests nearby — it doesn't need to be in direct contact with skin.

Standard e-stim safety rules apply regardless of wireless control: never use electro stimulation above the waist or near the heart, never if you have a pacemaker or are pregnant, and never place electrodes on broken skin or across the chest. The remote control aspect doesn't change these boundaries — it only changes who operates the controls.

Safety & Control

Because someone else controls the intensity, establish clear stop signals before you start. A safeword isn't enough if you're gagged or restrained — agree on a physical signal (dropped object, specific hand gesture) that means stop immediately. The person holding the Cluster Buster remote is responsible for watching for that signal and responding instantly.

The receiver has no emergency shut-off on the unit itself — all control happens through the remote. Make sure the remote holder understands how to reduce intensity quickly and knows your limits. Start at the lowest settings and build gradually, especially if this is your first experience with remotely controlled e-stim. What feels like mild tingling when you control it yourself can feel much more intense when you're not anticipating the change.

Never leave someone alone while using remote-controlled electro stimulation. The lack of direct control is the appeal, but it also means they can't adjust or stop the sensation themselves if something feels wrong.

Charging & Maintenance

The Sultry Sub receiver is battery-powered (the specifications don't detail battery type or life — check the included documentation). Keep it dry and clean the exterior with a damp cloth if needed, but avoid getting moisture in the connection port. Store it with your other e-stim accessories, away from extreme temperatures.

The 2mm cable connection should remain snug — if it becomes loose over time, the signal may be unreliable. Check the connection before each session to ensure consistent contact. If you own multiple receivers, label each one with its assigned channel number to avoid confusion during setup.
