Tantus Fantasy Gag Onyx

The Tantus Fantasy Gag is a silicone mouth gag on leather straps: a shaped mouthpiece 2.7 in long, Velcro adjustment for head size, and straps that snap off so the silicone can be boiled or washed in the dishwasher. Tantus made it for people who are into oral fixation.

• Agree a non-verbal stop signal first, such as dropping an object or tapping three times.
• Check breathing through the nose is easy before fastening.
• Never leave someone gagged alone, and remove it at once if they feel sick.

From Tantus’s store listing.

A ball gag holds the mouth open around a sphere; the Fantasy Gag puts a shaped piece in the mouth instead. A breathable glow ball gag costs less if you just want to try the idea.

Is the Fantasy Gag a ball gag?

No. It’s a shaped silicone mouthpiece, 2.7 in insertable and 1.7 x 1.5 in across, on leather straps.

How does it fasten?

With Velcro on the leather straps, which Tantus chose so the fit adjusts to different head sizes.

How do I clean it?

Snap the leather straps off, then boil the silicone or put it in the dishwasher. Wipe the leather separately.

Does silicone taste of anything?

Tantus picked silicone because it’s tasteless and odourless.

Is it safe for long scenes?

Keep scenes short at first, agree a non-verbal stop signal, and never leave a gagged partner alone.
