Mouth Gag Strap-On Dildo – 12cm Silicone Fantasy Bite Gag Harness

👄 Mouth Gag Strap-On Dildo – 12cm Silicone Fantasy Gag on an Adjustable Leather Head Harness

This is a mouth-held strap-on for couples: a hollow 12cm fantasy-sculpted silicone piece mounted to a leather head harness, so the wearer holds it between their teeth while the sculpted shaft faces outward for their partner. It works two ways in the same session, as a gag that keeps the wearer quiet and as a hands-free oral strap-on, which is why it sits in the SM and power-exchange corner of the catalogue rather than with ordinary dildos. The harness comes in black, orange or pink leather with gold-tone hardware, and the whole set arrives in a lined presentation case.

📏 Mouth Gag Dildo Measurements: 12cm Long with a 3.5cm Hollow Cavity

A gag lives or dies on whether it actually fits a mouth, so here are the manufacturer's measured figures rather than vague sizing talk.

• Total length: 12cm
• Width across the head: 4.5cm
• Width at the narrow section: 3.7cm
• Width across the widest lobed section: 5.9cm
• Mounting collar width: 4.5cm
• Open end height: 6.2cm
• Inner cavity width: 3.5cm
• Through hole at the tip: 1cm across
• Wall thickness: 0.5cm
• Weight of the silicone piece: 136g
• Model code: M-KSCG4011

The number to check before you buy is the 3.5cm inner cavity and the 6.2cm open end. That is the part your mouth meets, and 12cm is the overall length including the shaft that stays outside.

💨 Why the Hollow Body and 1cm Through Hole Matter on a Gag

The silicone piece is not solid. It is a 0.5cm-walled shell with an open cavity and a 1cm hole moulded right through the tip, so air passes from front to back rather than the mouth being sealed shut. That is the single most important feature on any gag, and it is also what lets the wearer be heard faintly enough to signal. It makes rinsing the inside straightforward too, because you can flush water straight through instead of trying to reach into a closed pocket.

Say it plainly though: no gag should ever be used on someone who cannot breathe comfortably through their nose, and neither partner should rely on speech as the safe signal. Agree on a hand signal or a dropped object before you start.

🦑 Soft Fantasy-Sculpted Silicone Instead of a Hard Ball Gag

Most gags are a rigid plastic or solid rubber ball that forces the jaw to a fixed width and gives nothing back. This one is moulded in soft body-safe silicone with 0.5cm walls, marbled in red and pearl with a raised creature-style texture along the shaft, so it compresses against the teeth instead of wedging them apart. At 136g it is light enough that the harness carries it without dragging on the head.

The trade-off is honest: soft silicone is a consensual play piece, not a secure restraint. A determined wearer can push it out, and that is a feature rather than a fault.

⛓️ How the Adjustable Leather Head Harness and Gold Hardware Work

The gag mounts to a two-part leather strap: one half is punched with a long row of slots, the other is plain, and gold-tone metal bars clamp them together so you set the length to the wearer's head rather than picking from fixed buckle holes. A fine chain with T-bar ends runs across the front of the silicone piece and clips into the side bars to hold it seated, and a decorative heart padlock charm finishes the front. Because it is a bar-and-slot closure, one harness covers a wide range of head sizes and it comes apart quickly when the session ends.

🎁 What Comes in the Presentation Case

The set ships in a lined hard case with a cut-out for each part, which makes it giftable and also solves storage, since silicone should not be left touching other silicone toys. Inside you get the hollow silicone gag, the two-part leather harness in your chosen colour, the connecting chain with T-bar ends, the gold-tone clamp bars and keeper loop, and the heart padlock charm.

🎨 Choosing Between the Black, Orange and Pink Harness

The silicone gag is identical across all three options and so is the price. Only the leather harness colour changes. Black is the classic BDSM look and photographs darkest. Orange is the boldest and throws the gold hardware into sharp contrast. Pink reads softer and more playful, which suits couples who want the scene to feel light rather than severe. If it is a gift and you are unsure, black is the safe pick.

🧼 Cleaning and Safe-Play Rules for a Silicone Mouth Gag

This one goes in a mouth, so clean it before and after every single use, not just after. Rinse warm water and a mild unscented soap through the cavity, push water out through the tip hole to flush the inside, and let it dry completely before it goes back in the case. Use water-based lubricant only, because silicone lubricant degrades the silicone surface. Keep the leather harness and the gold hardware away from water and wipe them with a dry cloth instead.

On play: agree on a non-verbal safe signal first, never leave a gagged partner alone, check in often, and take it off at once if breathing feels laboured, if the jaw aches or goes numb, or if the harness leaves marks. Keep sessions short until you both know how it feels, and if the shaft is also being used for penetration, wash it between uses on different body areas.

🎯 Who This Mouth Gag Strap-On Suits

It fits couples already exploring dominance and submission who want a gag that does more than silence, and people who like the idea of a hands-free oral strap-on without a full body harness. The fantasy sculpt also appeals to anyone collecting monster and creature-themed toys who wants a wearable piece in the same style, and as a boxed set it works as a gift for a partner.

It is not the right pick if either of you is new to breath-adjacent play and has not agreed on safe signals, if the wearer has jaw problems or cannot breathe easily through their nose, or if you want something rigid and genuinely inescapable.

📋 Silicone Mouth Gag Strap-On Specifications

❓ Mouth Gag Strap-On Dildo FAQ

How is this worn?
The hollow end sits in the mouth and the leather harness straps around the head, so the sculpted shaft points outward and stays in place hands-free.

Can the wearer breathe with it in?
The body is hollow with a 1cm hole through the tip, so air passes through. It should still only be used by someone who breathes comfortably through the nose, and never as a sealing gag.

Will it fit my mouth?
The part that meets the mouth has a 6.2cm open end and a 3.5cm inner cavity. The 12cm figure is the total length including the shaft that stays outside.

Can it be used for penetration?
Yes, that is the point of the outward-facing shaft. Wash it between uses on different body areas.

Is it escapable?
Yes. Soft silicone flexes and the harness releases quickly, so treat it as a consensual play piece rather than a secure restraint.

How does the harness adjust?
Two leather straps clamp together with gold-tone bars through a punched row of slots, so the length sets anywhere across a wide range instead of at fixed buckle holes.

What is the chain for?
The fine chain crosses the front of the silicone piece and clips into the side bars, keeping the gag seated on the harness.

What is in the box?
The silicone gag, the two-part leather harness in your chosen colour, the connecting chain, the gold-tone clamp bars and keeper loop, the heart padlock charm and a lined presentation case.

Does the harness colour change the gag?
No. All three options use the same silicone piece at the same price. Only the leather colour differs.

How long can it be worn?
Keep sessions short, especially at first. Remove it immediately if breathing feels laboured or the jaw aches or goes numb.

What lubricant should I use?
Water-based only. Silicone lubricant damages the silicone surface.

How do I clean it?
Before and after every use, rinse warm water and mild unscented soap through the cavity, flush it out through the tip hole, and dry fully. Wipe the leather harness with a dry cloth and keep it away from water.
