Fleshlight Review: Kissa Sins Insatiable – New Queen of Fleshlights

Fleshlight Kissa Sins Insatiable

Kissa Sins entered the world of adult entertainment in 2015 at the age of 28, after meeting her partner, porn actor Johnny Sins. With her long hair, smoky brown eyes, and full, kissable lips, Kissa Sins is a porn fan’s dream and she soon attracted a loyal following of admirers.  

Her late start didn’t hold her back. In her relatively short career so far, Kissa Sins has worked successfully as both an actress and producer and in 2018 she won the AVN Award for Best Girl/Girl Sex Scene. 

Previously a wedding planner and entrepreneur, Kissa Sins was no stranger to the world of business either. She used her expertise to launch YouTube channel SinsTV in 2017 and later teamed up with Fleshlight to make two exclusive textures: the anal sleeve ‘Sinner’ and the vaginal sleeve - Insatiable.

The Insatiable is well named; after trying it once I became greedy for more and I don’t know if I’ll ever get bored of it.

Fleshlight Kissa Sins Insatiable Review

Sleeve and Texture

Fleshlight Kissa Sins Insatiable - sleeve

The Insatiable sleeve is heavily textured, with five separate sections to provide a variety of sensations. 

The first section is shaped like a cone, tapering to a narrow point 1.9” (49 mm) from the entrance of the sleeve. The walls of this chamber are crisscrossed with deep ridges in a lattice, leaving diamond shaped ‘pockets’ between them. 

The second chamber is shorter - just 1” (24 mm) long - and round; the edges curve away from the end of the cone before narrowing again to create a constriction before the third chamber begins. Tiny round bumps line the walls.

Next comes the main event; the long central section of the sleeve. It’s 2.4” (60 mm) long and surrounded by very obvious wide bumps which protrude from the sides. They have the shape of slightly squashed half-spheres with flattened edges. Four staggered rows of these bumps are followed immediately by smaller, circular protrusions with pointed tips which lean slightly into the channel, pointing back toward the sleeve entrance.       

The final two sections are ribbed. Three ‘square’ ribs run around a narrow section before the final chamber begins, 6.4” (162 mm) from the entrance. The texture in this section is a thick, spiraling rib which winds around the channel until the end of the sleeve.

How the Kissa Sins Fleshlight Feels

I was prepared for the narrowing just inside the masturbator but the intensity of the cross-hatch pattern took me by surprise. 

The size of the ribs means that they grip and pull on the skin of the penis, creating an intense and very stimulating feeling right from the start. 

The tight entrance to the second chamber was welcome and I enjoyed pushing through this a few times; the tiny bumps are just big enough to feel on the sensitive tip of the penis and the first two sections alone were almost enough to finish me off the first time I tried it.

Moving further in, the deep bumps in the center section of the sleeve are very obvious and feel absolutely amazing when they’re positioned just right. 

I’d recommend twisting the sleeve when you reach this section as the effect changes depending on where, exactly, the bumps are positioned. 

The whole thing is very intense without feeling rough on a sensitive penis and the orgasm from this sleeve was overwhelming.


The complex textures in the Insatiable make several deep grooves and gaps which trap lube and residue and make cleaning difficult. 

It will take time and persistence to get it clean but it’s worth doing properly. 

Run plenty of clean water through the channel from both ends and trap some inside, covering the ends with your fingers, before giving the whole thing a shake trying to wash out the ‘corners’. Repeat until you’re sure the sleeve is clean and leave it out to dry (this will also take longer than usual) in a warm spot. 

Fleshlight Kissa Sins Insatiable Review Summary






How I rate Fleshlights explained

I was totally blown away by the Insatiable!

Everything about it came together to push me over the edge far sooner than I expected, and once I was done I couldn’t wait to try it again!

I often find that intense sleeves become almost unbearable on an sensitive penis and have to stop moving or pull out before orgasm but the Insatiable gets the intensity just right. 

The Insatiable is, without a doubt, my new favorite Fleshlight!

Love the Insatiable? Why not try one of these Fleshlights?

For the fans of Kissa Sins, her anal Fleshlight sleeve, Sinner, is of course an obvious choice.

Stoya Destroya: The Destroya is often recommended as the sleeve for intensity lovers and its enduring popularity speaks for itself. However, it’s tighter and less forgiving than the Insatiable so proceed with caution if you are sensitive to over-stimulation.

Autumn Falls Cream Fleshlight's intense textures create a strong pressure-release sensation which delivers one of the best Fleshlight orgasms ever. Read my Autumn Falls Cream review.

Other my favorite intense Fleshlights are Romi Rain Storm and the excellent blowjob Fleshlight, Turbo Thrust.
