What does auto suction add to a masturbator? A manual stroker relies on your hand for all the movement and grip. Auto suction uses a motor to pull air inside the toy, so the sleeve draws on the penis in a rhythm without you pumping anything. The distributor compares the feeling to oral sex. On the Jock Blast the suction has 3 speeds and 6 patterns. Vibration through the sleeve is a separate function with its own 3 speeds and 6 patterns, and the two can run together or apart.
Jock Blast: suction and vibration in one stroker
The Jock Blast is a 9.1 inch automatic masturbator, 3.3 inches wide, built around powered suction. The opening is 1.1 inches across and leads into a soft, stretchy TPE sleeve with 5.3 inches of insertion depth. A ridged tunnel grips the shaft all the way from the entrance to the far end.
Suction and vibration each have 3 speeds and 6 patterns and can be used together or separately. The sleeve pulls out of the shell for cleaning. The shell is splash-proof and the toy is rechargeable. Materials are TPE, ABS plastic and silicone, all phthalate-free, in black.
Best for: For men who want more than a hand-powered sleeve and like the idea of suction that works by itself. It suits solo sessions and edging, since suction and vibration can be changed independently. A partner can also hold and control it.

How to use
Charge the toy before first use. Check that the sleeve is seated properly in the shell. Apply water-based lubricant to the opening, inside the first part of the tunnel and on yourself. Slide in while the toy is off; the 1.1 inch opening stretches as you enter. Hold the masturbator steady and start with vibration or suction on the lowest speed. Try each function alone before combining them, then move through the patterns. When you finish, switch it off, pull the sleeve out of the shell and wash it straight away.
Care
- Use water-based lubricant only; other types can damage TPE.
- Remove the TPE sleeve and wash it with warm water and toy cleaner after every use.
- Wipe the shell clean. It is splash-proof, so never submerge it.
- Pat the sleeve dry and let it air fully before refitting it.
- Store cool and dry, away from sunlight and apart from other toys.

Frequently asked questions
Will it fit me?
The opening is 1.1 inches in diameter and the sleeve is soft, stretchy TPE, so it expands as you enter. The insertion depth is 5.3 inches. If you are longer than that, the sleeve covers the upper part of the shaft.
Can I use suction without vibration?
Yes. The two functions work together or separately. Each has 3 speeds and 6 patterns, so you can run suction alone, vibration alone, or stack both and adjust them to suit the moment.
How do I clean it?
Pull the TPE sleeve out of the shell. Wash the sleeve with warm water and toy cleaner, then pat it dry and let it air. Wipe the shell with a damp cloth. Do not put the shell under water.
Is it waterproof?
No. The shell is listed as splash-proof only. It can cope with splashes while you clean up, but it should not be used in the bath or shower or held under a running tap.
What lubricant should I use?
Water-based lubricant. The sleeve is TPE, and oil-based or silicone-based lubricants can break that material down. Apply it to the opening and to yourself before you start, and add more if the grip begins to feel dry.
