Some cravings call for a lot of presence, and this strap on answers with generous scale and lifelike detail in equal measure. Built for anyone who wants a serious, realistic addition to harness play, it works locked into a Vac-U-Lock system or held in hand as a standalone dildo.

The dual density build is what makes it feel less like a toy and more like the real thing: a firm inner core holds its shape under pressure while the softer outer skin gives under your grip, mimicking the give of an actual erection. The included O-ring is sized to suit the toy's substantial girth, so it seats securely in any compatible harness without a separate purchase. There's a well detailed, hefty ball sack to grind against for anyone who likes to take things all the way, and the smooth Ultraskyn surface glides for vaginal or anal play. Pair it with the Vac-U-Lock suction cup base, sold separately, and it plants itself on a flat surface for hands-free riding.

Made by Doc Johnson in Ultraskyn over a TPE core, this dildo is waterproof, phthalate-free, made in the USA, and built to pair with any Vac-U-Lock harness or accessory.

Customers praised the realistic ULTRASKYN material and substantial size, with many noting "the perfect blend of length, girth, and firm softness." However, several shoppers found the product too rigid and inflexible for certain positions. Fast shipping and reasonable pricing were appreciated. Not recommended for beginners due to significant girth.

Not very flexible

I love the girth and the strength of the dildo, but because of its size, it’s not very flexible, so the positions I can try out are somewhat limited.

Superb

MMMMMMMM 😍 I love how filling this dildo makes me feel. It’s so big, so tasty, everything I was looking for in a man but couldn’t find!

Master series

There are a lot of large toys on the sex toy market, and I own a lot of them. But I cant use them as often as this particular toy made from the wonderful ULTRASKYN material. It has the perfect blend of length, girth, and firm softness without being squishy.

Wide and powerful

I did not expect it to be so wide. THe length, okay, I wanted it, but THE GIRTH GIRL. A lot to take in, especially if you’re new and not used to the thickness.

Wow

This is definitely not for beginners. It has thick luscious veins up and down and damn do you feel those. It is the perfect width for me to make me feel full without being too difficult to use. It's got a really heavy base so hands-free play is really easy.

Hard PVC

Being in love with huge black cocks, I wanted to treat myself to one of these and chose the 12-inch black strap-on dildo. The shipping was quick, and the price was affordable. Once I unpacked it, I found it nicely textured and realistic-looking... but, I noted it is rigid and unbending upon using it, which is not something I enjoy.

Oh, Yessss!!!

I recommend this toy to anyone looking for some extra girth and length!

Got one for the wife

Buying one for the wife to play with seemed like a good idea at the time. However, she loves it so much that she makes me use it often on her, and we have an instant threesome without having an actual third person in the mix. We don’t have a fuck machine, but I’ve fashioned a harness using the Vac-U-Lock system to keep the dildo upright on a chair so my wife can ride it, and I can join in at any time.

Somewhat hard for me

Fast shipping and reasonable price, but the dildo is a bit hard for me. I like the realistic texture and feel. Still, once inserted, I found it stiff and unbending, which does not suit me.

Incredible

OMG! OMG! OMG! I’m in love with this dildo. I’ve bought it to use it with my fuck machine but found that I enjoy using it as a handheld dildo and fuck myself with the massive cock. Everything about it is perfect for me, but I’m used to a bigger size dick.

Too girthy for me

Maybe I’ve overestimated myself, but this is such a massive toy that I can’t use it comfortably. Still looks good.

Use plenty of lube

Fast shipping and a reasonable price for such a good product. However, if you plan on training yourself to take the entire 9.5 inches of insertable length, don’t be stingy with the lube.

Nice big dildo

The 12-inch strap-on is definitely for the size-curious, as it is massive in length and width. I’ve been training myself for this cock, and while it can be used in a strap-on, I like to use it as a handheld dildo and control how much I take it.
