Cyberpunk Sheath

Cyberpunk Sheath is a hollow penis sleeve in platinum-cured silicone, shaped like a piece of armor: 21.5 cm (8.5 in) long, 15.5 cm (6.1 in) around at the widest point, 233 g (8.2 oz). The wall is thin and soft, and the tanks and rivets on the outside press just as soft. Worn, it turns the wearer into something machine-built. Taken, the tapered head goes in first, then a stack of rings behind it, each one a small pop, and then the armored body behind those.

There is no animal under this one. The shape is machine parts: a hydraulic tank on each side, a corrugated hose, plates riveted over the shaft, with the tapered head and the rings up front. The joke of it is that none of that hardware is hard. Press it and it gives.


AT A GLANCE

A hollow, wearable sheath shaped like machinery: a tapered head, a stack of rings behind it, then tanks, hose and riveted plates, and an open end held on by a thickened ring. Worn, the thin wall warms through and stops registering, leaving the weight and the look. Taken, the head wedges in narrow, the rings pop past one at a time, and the rivets add a fine drag until the widest part fills you at 15.5 cm (6.1 in) around. It suits a partner who wants plenty going on without a big stretch, and a wearer who wants a war machine in the mirror. If you want to be stretched hard, this is the wrong piece. One size: 21.5 cm (8.5 in) total, 13.7 cm (5.4 in) usable.

  • Type: Penis sleeve, machine-armored fantasy shape, tapered head, no knot
  • Material: Platinum-cured silicone, body-safe, phthalate-free
  • Design: Tapered head, stacked rings behind it, hydraulic tanks and riveted plates along the body, hollow throughout
  • Base: Open base with a thickened ring at the opening
  • Sizes: One size — 21.5 cm (8.5 in)

THE HEAD

The head is a smooth cone, close to a half-dome at the tip, and it goes in at 15 cm (5.9 in) around before the rings start. The rings are packed close behind it, and each one is its own small event: a push, a give, then the next. That is the rhythm, and it runs in reverse on the way out. No knot. Just the count.

Circumference near the head: 15 cm (5.9 in) · Usable length: 13.7 cm (5.4 in)

THE ARMOR

Behind the rings the body turns into machinery: a hydraulic tank on each side, a corrugated hose, plates riveted over the rest, and a line of muscle down the back where the metal ends. That is what the eye reads. What the body reads is different. The rivets are a fine grain you pick up on slow strokes. The hose creases when it is compressed and presses back as it opens. Press a thumb into one of the tanks and it folds like the rubber bulb on a turkey baster, then fills out again. Looks like armor. Squishes like a gummy. That gap is the point.

Circumference at the widest point: 15.5 cm (6.1 in) · Total length: 21.5 cm (8.5 in)

THE OPENING

The far end is open, with a thickened ring around the mouth, and the ring keeps it on: no strap, no hand. The wall between ring and head is thin, so once it has warmed through, what the wearer notices is the weight, 233 g (8.2 oz). You'll feel that. The opening stretches to fit; 14 cm (5.5 in) around at rest is the number to start from. Some people buy this for how it feels. We suspect that is not the main reason.

Circumference at the open end: 14 cm (5.5 in) · Weight: 233 g (8.2 oz)

Max diameter (calculated from circumference): One size 4.93 cm / 1.94 in

The open end is 14 cm (5.5 in) around at rest and stretches over the wearer; the partner checks the max circumference against what they already take. Warm up first, since the rings arrive one at a time and are more interesting once you are already open.

FIRMNESS
This is a soft piece through and through: the tanks, rivets and plates fold under a thumb the same way the plain wall does, and it loosens further once it has warmed against skin.

PLATINUM SILICONE
Platinum-cured silicone throughout. Non-porous, odorless, and compatible with water-based lube. Use silicone lube only if you have tested it on the base first.

CARE
Wash with warm water and mild soap before first use and after each use. Boil for 3–5 minutes or wipe with 10% bleach solution to sanitize. Store dry, away from direct sunlight and other silicone toys.

Beautiful and functional

My partner and I love the design. The steampunk aesthetic is spot on. The added length and girth does not disappoint either.
