Leviathan Silicone Dildo From John Thomas Toys

Written by  Jan 22, 2024

Leviathan is perfect for deep play with lots of textures

I really enjoy reviewing good quality sex toys. So when John Thomas Toys asked if I would like to review some more of their designs, I jumped at the chance.

JTT produce some stunning and some eye-watering designs. I never know what they will send, so it always feels like Xmas when the boxes arrive.

I cannot say no to good quality items, so I cannot say no to JTT. They produce good quality dildos, stretchers and depth play toys.

After saying yes, I just needed to wait for the delivery driver to turn up at my door. After a short wait of a few days, the driver stood at my door with four large boxes. This review is for the Leviathan dildo.

Delivery & Packaging

On the delivery of the large box, I could immediately see that it was sent discreetly. The plain, robust cardboard is well sealed with brown parcel tape. The shipping label has my address but does not show the JTT name or the website address.

I appreciate the care taken to ensure my privacy. The delivery driver has no clue about the very naughty content they have just dropped off. I will add that this is the first box I have received from JTT that wears a 'heavy caution' sticker.

Inside the box, underneath the packing paper, are four sizes of the Leviathan dildo. Each dildo is covered in a heat-sealed transparent plastic film. Several stickers decorate the film: one with a firmness rating, a JTT logo, and, most importantly, one that reminds you to wash before use. It is essential to ensure you wash your dildo thoroughly to remove any post-processing debris.

I also received four JTT branded storage bags and four vac-u-lock compatible suction cup holders.

Materials and design

Leviathan is a platinum-grade silicone dildo. This is an expensive material but ideal for insertable toys. Silicone is not only latex, PVC and phthalate free, it is also non-porous, hypoallergenic and body-safe.

JTT uses copper moulds to manufacture all their toys. This is a more expensive method than some other manufacturers use. Copper moulds are an excellent way to ensure that every item out of that mould has exactly the same features as the first.

Leviathan is an amazingly detailed tentacle dildo. The tip is a narrow, rounded end with several arrow-shaped grooves. The tentacle's width slowly expands as you move down to the base. Along the length of the tentacle are two rows of suckers. The suckers grow larger as you move towards the base from the tip. The suckers also twist around the length giving the appearance of it twisting around looking for something to attach to.

I just love the colur of this dildo and the textures feel amazing.

The suckers are on a raised section, making the dildo thicker in the area of the suckers. This raised section will also provide extra sensations to enjoy. Between the two rows of tentacles is a thin groove which slightly separates them. This makes the tentacle appear more realistic.

The design also has the texture of skin with wrinkles, which will provide an excellent surface for holding lube as well as giving some great texture.

I received all four sizes of Leviathan in the medium firmness rating. The design of Leviathan means that the base is quite large and firm, with the rest of the design being very flexible.

The suckers go down the length leaving just a small area at the base smooth. In this smooth area is the JTT logo. Underneath the base is a vac-u-lock compatible hole.

The medium firmness rating is a little firmer than the soft rating but still provides a little squish. Even though it is slightly firmer, the design and weight of the silicone mean that it is a slightly floppy dildo.

JTT provides a black faux velvet storage bag for each dildo. The bags are made with strong faux velvet and feature the JTT name and logo printed in white on one side. The bags have a drawstring closure to help keep your toy clean of dust and fluff.

JTT also provides a free vac-u-lock compatible suction cup holder with every compatible dildo. The holder is designed and manufactured by JTT.

I love it when dildos are vac-u-lock compatible and the suction cup adaptor that JTT provides for free works really well.

Performance

Because the tip is so narrow, I and sub 'r' decided to upgrade from our usual size. sub 'r' enjoyed the medium, and I played with the large.

I always have my water-based lube on hand whenever I play with a silicone toy. So, with my J-Jelly lube in hand, I laid back with my freshly washed large Leviathan.

I really enjoy clit play, so I start off my session by lubing up my clit and rubbing the tip of the tentacle across my clit. The feel of the now lubed-up tip makes it feel slimy in the most delicious kind of way. Gliding the smooth part of the tip soon has my clit engorged and my pussy getting wet.

Due to the flexibility, I could easily insert the tip into my pussy, whilst rubbing the length over my clit. The feel of the tentacle and suckers sliding inside my wet pussy was amazing. Adding in the sensation of it rubbing against my clit and I am quickly squirming.

The sensations of the tentacle sliding inside my pussy with the gradually expanding shaft and the suckers was fantastic.

The rounded tip was easy to insert and the textures on those suckers feel amazing when you thrust with it.

I thoroughly enjoyed the feel of the stretch as I took more of the length inside my pussy. The twist of the tentacles and the suckers feel amazing against my clit and pussy walls. Adding a slight twist whilst moving the tentacle in and out of my pussy provided toe-curling sensations that soon had me orgasuming.

I also had a few sessions enjoying the vac-u-lock compatibility. One, I tried out the suction cup holder provided by JTT, and one, I used a fucking machine. The suction cup holder works exceptionally well on clean, flat surfaces. So, I stuck it onto the bathroom tiles before attaching the dildo. Because Leviathan has a thin top design, he is a little floppy. Holding him up at the right angle while inserting him inside helped. I soon sank back against the length I could manage.

I am always amazed at how well the small suction cup holder works. After play, I easily removed the dildo from the suction cup holder. Removing the suction cup was a little more of a challenge. I needed to pry the bottom section slightly off the tiles to break the seal.

Using Leviathan on my fucking machine was a great way to enjoy a faster speed when I wanted. I did need to weigh down the legs due to the weight. I also needed to guard the dildo inside my pussy, to ensure it went where I wanted it to go. I enjoyed the easy way I could quickly alter the thrust speed. This method ensured that I had toe-curling orgasms every time.

I cannot stress enough, just how good these textures feel as toy twist and thrust with it.

Whilst cleaning after play, it is essential to ensure that any goo and lube are removed. I prefer to use an ultra-soft toothbrush with hot water and anti-bacterial soap. If you prefer, you can clean it in a dishwasher. Once mine is clean, I place it on some kitchen roll to air dry. When fully dry, I place it into the storage bag, ready for my next play session.

sub 'r' really enjoyed her play sessions with the medium-sized Leviathan. She even squirted at the end of each play session.

Final thoughts

Leviathan is a fantastic dildo if you want lots of sensation and enjoy fantasy dildos. You can also enjoy Leviathan as a depth play dildo.

The vac-u-lock compatible hole means that you can not only enjoy using this using the vac-u-lock suction cup holder, but you can use it with a strap-on or a fucking machine.

Leviathan is a realistic tentacle with many fun ways to play with. If using it on a sub, you can even use the tip to spank them with.

The thinner tip means you can even use this one anally, even if you do not enjoy using wide anal plugs or toys.

Both I and sub 'r' give Leviathan a huge double thumbs up.

I was sent these four Leviathan dildos by John Thomas Toys and I would like to thank them for giving me the opportunity to review it for them.
