The OXBALLS WaterSport Strap-On Gag is a bondage gag built for piss play: a wide funnel sits over the mouth and drains straight into a short mouth tube, all moulded as one piece. It's for couples who already know watersports is on their list and want a dedicated piece of gear that stays put, rather than improvising. OXBALLS designed this black version to be lighter and closer-fitting than its earlier, bulkier urinal gag.

How the funnel and mouthpiece work

The funnel is deep and wide, with a channel that runs straight down into the mouthpiece. Because the tube is part of the same moulding, there are no seams or joins where liquid could escape, and the strap tabs are shaped to lie flat against the face. The wearer holds the 1.25 in tube in their mouth and breathes through the nose. The person standing over them aims into the bowl, which is broad enough that a bit of drift doesn't matter.

Straps and fit

OXBALLS describes the harness as neoprene straps closed with black snaps that won't rust. The straps cross in an X at the back of the head, and an extra strap runs over the top of the head and can be removed. Every strap adjusts, so it fits a wide range of head sizes. Leave the top strap on when the wearer will be lying back or moving their head; take it off for a quicker, simpler fit.

Before you play

Talk through limits first, including what goes into the funnel and how much. A gag stops clear speech, so agree on a non-verbal stop signal, such as tapping the partner's leg three times or dropping a held object. Never leave someone alone while gagged, and check their breathing is comfortable through the nose before you start. Many couples do a first run with plain water so the wearer learns the flow and how to swallow or let it overflow without panic. Lay down a towel or play in the shower, because some spillage around the edges is normal.

Material and cleaning

The gag is moulded from FLEXtpr, OXBALLS' own firm, durable thermoplastic, which the brand says is non-toxic and phthalate-free. It's compatible with water-based or silicone lube if you want to ease the tube in. Wash the gag in warm soapy water after every use, paying attention to the inside of the tube, and air-dry it. The straps can be washed the same way. Store it on its own in a breathable cloth bag; OXBALLS suggests a cotton sock works too.

Who this bondage gag suits, and who it doesn't

This is a specialist kink item, not a starter gag. If you want to try being gagged without the watersports element, a simple ball or bit gag is easier to begin with. If piss play is already part of what you do, this design solves the mess and fit problems a homemade setup has. A white version of the same gag is also listed.

Helpful Information

Frequently Asked Questions

Helpful answers about OxBalls WaterSport Strap-On Gag - Black.

What is a watersports gag used for?

It's for urine play. The funnel catches the flow and channels it into the wearer's mouth through a short tube, while the straps keep everything in place. It removes the need to hold anything by hand and cuts down the mess compared with improvising.

Does the WaterSport gag leak?

OXBALLS designed it so the tube and funnel are one seamless moulding, with no gaps at the join. Leaks are more likely to come from the edges of the funnel if the wearer's head tilts, so play over a towel or in the shower anyway.

How do I adjust the straps to fit?

Loosen everything, place the tube in the mouth, then tighten the X straps at the back of the head until the funnel sits snug without pressing on the lips. Add the top strap if the wearer will be lying down or turning their head.

Can the wearer breathe comfortably?

Breathing happens through the nose, so the wearer needs a clear nose before you start. If they have a cold or blocked sinuses, skip it that day. Keep sessions short at first and remove the gag immediately if they signal.

How do I clean a bondage gag like this?

Wash the FLEXtpr gag and the straps in warm soapy water after each use, run water through the tube, and let everything air-dry completely. Our toy cleaning guide has more on drying and storage.

Is this a good gag for someone new to BDSM?

Not as a first gag. It's made for a specific kink. If you want to explore being gagged in general, start with a simple ball or bit gag and agree on signals; come back to this if watersports becomes part of your play.

What's the difference between the black and white versions?

The listings are for the same OXBALLS design. Colour is the visible difference: black looks more discreet in photos and in a gear bag, while white makes it easier to check the inside of the funnel and tube are fully clean.
