Dungeon Lab Hyena Posture Trainer

Modular CBT Ball Stretcher for Advanced E-Stim Play
The Dungeon Lab Hyena Posture Trainer is made for players who want more than a simple ball stretcher. This premium Dungeon Lab accessory blends CBT, ball restraint, and electro-stimulation into one highly configurable system. The Hyena Posture Trainer uses interchangeable half-rings to help you choose the right level of fit, hold, and tension. It can be worn as a secure ball-stretcher style device or built out into a more restrictive posture trainer. Dungeon Lab designed the Hyena Posture Trainer for bold, technical, body-aware play.
Compatible with Dungeon Lab Coyote for Conductive Electroplay
The Hyena Posture Trainer connects with the Dungeon Lab Coyote e-stim system, giving experienced users more targeted sensation through conductive contact points in the ring design. Positive and negative input options sit on both sides of the rings, allowing controlled stimulation where it counts. This makes Dungeon Lab electroplay feel more precise, responsive, and customisable. The Hyena Posture Trainer is especially suited to players who enjoy cock and ball e-stim, CBT training, and intense restraint scenarios with clear limits, careful setup, and the right compatible power unit.
Expandable Posture Control with Optional Dual-Zone Intensity
For players who want extra bite, the Hyena Posture Trainer supports add-ons that change the whole mood of the scene. The optional bottom plate creates a second stimulation zone for top-and-bottom ball contact, while the attachable side pieces convert the device into a humbler-style posture trainer. That means more containment, stricter positioning, and a stronger feeling of surrender. Dungeon Lab gives this modular device a body-safe design focused on adjustability, durability, and creative control. Start slow, communicate clearly, and let the hyena grin do the rest.

Use Instructions

Customer Tips
• This is an advanced CBT and e-stim accessory, best suited to experienced users.
• Use plenty of time for setup. Rushing restraint gear is never sexy.
• Check circulation during longer scenes. Skin should not become cold, blue, numb, or sharply painful.
• Do not use e-stim if you have a pacemaker, implanted electronic device, heart condition, epilepsy, or if you are unsure whether electroplay is safe for you.
• Keep e-stim away from the chest, head, and broken skin.
• Pair with clear safewords, sober play, and a trusted partner for restrictive scenarios.
