Signature Cocks Jax Slayher 10 Inch ULTRASKYN Cock with Removable Vac-U-Lock Suction Cup Chocolate

The Jax Slayher Signature Cock is a 10 in realistic dildo molded directly from the adult star and bodybuilder, made by Doc Johnson in its dual-density ULTRASKYN: a soft, skin-like outside over a firmer core, with textured veins and a curved shaft. It comes with a removable Vac-U-Lock suction cup, so it can stand on its own or go in a harness.

This is a big toy, 9 in insertable and 2 in wide, for experienced users who want size and realism together. Doc Johnson says the material warms to body temperature as you use it. This one is the chocolate colour.

From Doc Johnson’s product specs.

If you mostly use toys around 1.3-1.5 in wide, like the Camtoyz Logan at 7 in long and 1.3 in wide, this is a clear step up in girth, not just length. With the Jax Slayher, go slow, warm up first and use plenty of water-based lube.

1. Dust the Vac-U-Port in the base with the included Vac-U Powder (or cornstarch).
2. Push the suction cup plug firmly into the port until it is seated.
3. Press the cup onto smooth, dry tile, glass or a sealed surface and twist slightly.
4. For strap-on play, remove the plug and fit the dildo to a Vac-U-Lock harness, or use it with an O-ring harness.

• The 10 in Jax Slayher dildo, in chocolate
• Removable Vac-U-Lock suction cup plug (3.5 in long, 3 in across)
• Vac-U Powder packet (0.18 oz)
• Storage bag for discreet travel and keeping it separate from other toys

Doc Johnson’s directions: clean with its toy cleaner or mild soap and warm water, pat dry, then dust lightly with ULTRASKYN powder or cornstarch so the surface stays soft and doesn’t get tacky. Store it on its own in a cool, dry place, and use water-based lube only. Doc Johnson lists it as phthalate-free and body-safe.

How do I attach the Vac-U-Lock suction cup?

Dust the hole in the base (the Vac-U-Port) with the included Vac-U Powder or cornstarch, then push the suction cup plug in firmly. Press the cup onto a smooth, dry surface for hands-free use, or take it out and use a Vac-U-Lock or O-ring harness.
