FlexiSpike Chastity Cage Size 4 CELLMATE

CELLMATE FlexiSpike Size 4 – maximum size, zero freedom

FlexiSpike Size 4 is the longest chastity cage in CELLMATE’s range — created for users who demand not only a proper physical fit, but also a deeper psychological submission reinforced by irreversible confinement. With a length of 105 mm and a consistent 39 mm inner diameter, this model offers full encapsulation of the flaccid penis — leaving no margin, no compromise. The extended shaft, four anatomical rings, silicone spike inserts, and dual locking systems make it a no-excuse device for absolute control.

105 mm of discipline – not for comfort, but for command

Size 4 is made for men who find shorter cages inadequate — whether due to natural anatomy or an intentional desire for deeper restriction. This model is not about accepting chastity — it’s about choosing extended isolation. Inside this cage, there is no space for tension, no possibility of erection, no room for resistance. The rigid shell responds to every signal with a firm “no.”

Metal-free construction – resilient, invisible, relentless

CELLMATE uses high-grade synthetic resin — lightweight, waterproof, sweatproof, and temperature-resistant. That means FlexiSpike Size 4 can be worn in the shower, while sleeping, at work, or while traveling. With no metal parts, it won’t trigger security systems. It’s a lockable device you can wear anywhere — and one that never backs down.

Hand-finished detail – built for comfort, not for mercy

Each unit is hand-polished to remove sharp edges and minimize friction. This smooth finish ensures you can wear Size 4 for hours — or days — without injury or discomfort. But make no mistake: this comfort doesn’t soften its purpose. It only removes excuses. No pain, no friction — just silence and obedience.

Four rings – an ergonomic trap with no escape route

The set includes four anatomical base rings in 43 mm, 46 mm, 49 mm, and 55 mm. These rings form a closed barrier around the penis and scrotum — preventing slippage, tilting, or any manipulation. The correct ring size locks the body in place and denies access completely — efficiently, and irreversibly.

Stability is the structure of power

When the shaft connects with the ring, FlexiSpike becomes a sealed, unshakable system. There’s no movement — not even the skin can shift. Forget trying to insert a finger. With its extended length, Size 4 increases contact surface — making every step, every stretch a constant reminder of the control it imposes.

Silicone spikes – internal pressure you command

Four sets of medical-grade silicone spikes (two pink, two black) are included. Their purpose? To apply subtle or forceful pressure from within — depending on how they’re configured. Use them individually, in pairs, or all at once. They’re not random — they’re part of a deliberate power dynamic.

A quiet but persistent reminder

Spikes can’t be removed without unlocking the cage — turning them into an ongoing extension of the keyholder’s will. Their presence says: “You’re being watched, even when I’m not there.” They don’t cut. They don’t bruise. But they don’t disappear either. Even in stillness, they speak.

Your rules, your lock – two modes of control

CELLMATE offers two locking options with FlexiSpike Size 4. A classic brass padlock with two physical keys — ideal for ritualistic or in-person scenes. Or an ABS adapter for disposable Stealth Locks — perfect for long-distance control, travel, or silent supervision. Either way, release is never up to the wearer.

Stealth Lock – invisible closure with undeniable control

The set includes five disposable plastic locks, each with a unique serial number. Once secured, they cannot be removed without cutting. Ideal for remote power exchange, for subtle everyday wear, or for quiet discipline. Control doesn’t need to be visible to be absolute.

Wear it all day – it’s built for real life

Despite its impressive length, FlexiSpike Size 4 remains discrete under clothing. No bulges, no discomfort, no limitation of movement. You can wear it to the office, on a plane, to the gym — and no one will know. But you will. The constant presence is yours alone to endure.

An ever-present weight – physical and mental

105 mm isn’t just a number — it’s psychological weight. FlexiSpike Size 4 fully surrounds the anatomy. No part remains free. No choice remains yours. Once the cage is shut, the only thing left is to submit. Quietly. Fully. Without exception.

The definition of absolute confinement

CELLMATE FlexiSpike Size 4 isn’t just the longest model — it’s a ritual of restriction. It’s for those who understand that chastity doesn’t have to hurt to be real. That control doesn’t require presence — only the right structure and the absence of escape. If you seek a device that stays with you — not just on your body, but in your mind — this is it. Size 4 leaves no room. It offers only one thing: total surrender.
