Why choose a silicone stroker? Many strokers are made of TPE or TPR, which are porous. Silicone is not porous, so it is simple to wash thoroughly and it does not hold on to odors the same way. The Asstra is made of phthalate-free silicone that the maker describes as soft, squishy and pliable, so it still gives when you squeeze it. Silicone toys need water-based lubricant. Silicone-based lubricant can damage the surface of the tunnel.
Asstra: an alien ass stroker with a tentacled entry
The Asstra Silicone Ass Stroker is a handheld masturbator from Creature Cocks, modeled on the back entry of an alien. The outside is blue, green and purple. Pink tentacles ring the opening, where they rub against you and grip the shaft on the way in. It measures 7 inches long by 3.1 inches wide, with an insertion depth of 4.3 inches.
Inside is a textured tunnel that grips and massages with every stroke. The whole stroker is premium, phthalate-free silicone, made soft and pliable so you can squeeze to adjust the pressure. In the brand's story it belongs to a tall, blue alien from Alpha Centauri.
Best for: It suits penis owners who like fantasy and sci-fi toys and want a stroker that is easy to keep clean. The 4.3 inch insertion depth focuses the texture on the head and upper shaft, and the soft body lets you control tightness by hand.

How to use
Wash the stroker inside and out with warm water and mild soap before the first use. Squeeze a good amount of water-based lubricant into the opening and work it down the tunnel with a finger, then add some to yourself. Hold the stroker in one hand and ease in past the tentacles. Stroke at your own pace, and squeeze the body to tighten the feel or relax your grip to loosen it. The tunnel is 4.3 inches deep, so do not force past the end.
Care
- Use water-based lubricant only, as the maker recommends.
- After use, flush the tunnel with warm water and wash with mild soap, then rinse well.
- Let it air dry completely, opening down, before you store it.
- Store it in a cool, dry place away from sunlight and apart from other toys.

Frequently asked questions
How deep is the Asstra stroker?
The insertion depth is 4.3 inches. The stroker itself is 7 inches long and 3.1 inches wide. If you are longer than the tunnel, the texture will work on the head and upper part of the shaft.
What does the tunnel feel like?
The inside is textured, and the maker says each stroke grips and massages the shaft. The silicone is soft and squishy, so squeezing the outside changes how tight it feels. Pink tentacles add contact at the entrance.
Which lubricant is safe to use?
Water-based lubricant. The maker recommends it for this stroker, and silicone-based lubricants are not suitable for silicone toys. Use plenty inside the tunnel so the texture glides, and add more if it starts to drag.
How do I clean it?
Rinse the tunnel with warm water straight after use, wash with mild soap and rinse again. Leave it to dry fully with the opening facing down so no water sits inside, then store it.
What is the difference between Asstra and Ursa?
They are companion alien strokers in the same colors and silicone. Asstra is the back-entry design, 7 inches long and 3.1 inches wide with a 4.3 inch depth. Ursa is the pussy design, shorter and wider at 6.3 by 3.5 inches, with a 4.2 inch depth.
