The Xenuphora Alien Tentacle was one of Uberrime’s first fantasy dildos. Their founding artist Marco sculpted the design by hand, creating unique ridges and suckers in clay that he then turned into a mold for silicone.

It was also the first Uberrime model that stood out to me. It’s so unique! The Splendid is/was Uberrime’s flagship (and it deserves that notoriety), but as a monster fucker, I’m drawn to their weirder designs. After pilfering this one during a recent trip to their studio, I realized it was time to write about it…

xenuphora design and features

For a fantasy design, the Uberrime Xenuphora isn’t very big. In fact, the widest part of the shaft is only 1.4 inches in diameter – the average width of a penis (or 3 fingers tucked together.) It’s less than 7 inches tall, and some of that is taken up by its unique base.

In an ocean of traditional tentacles, the Uberrime Xenuphora stands out with its wonderfully strange shape. The triangular tip reminds me of a squid’s hat-like top fin.

The Xenuphora’s curved shaft is lined with fat donut suckers on the front and spine-like ridges down the back and sides. Rather than curve forward, like most g-spot/prostate dildos, the Xenuphora is angled backwards.

This dildo doesn’t end with a regular toy base. Instead, the Xenuphora flares out with additional ridges that end in round little “spikes.” There’s two larger spikes (one in front, one in back) for added flair (or maybe extra stimulation, if it lines up with your anatomy.)

Uberrime chose a medium-firm density for the Xenuphora to help its texture stand out in use. You can easily bend this dildo in half, but it’s less squishy than the Uberrime Teuthida.

According to its fantasy backstory, Xenuphora are aquatic creatures that live in thriving colonies on an ocean planet. They stick to rocky cliffs like anemones and use their vibrant colors to attract prey. It definitely works on me!

There’s something distinctly psychedelic about how these bright colors are marbled. I love how the razor-thin ribbons of purple and green unfurl in drippy lines over hot pink. It’s so trippy. I also love that the head and spikes are done with more solid pops of green to stand out.

Cleaning this toy is a little trickier than a non-textured dildo. Gunk gets caught in its suckers and divots. But like all silicone sex toys, cleaning it only requires some soap (we use non-scented handsoap) and hot water. Just make sure to swirl those suckers with your pinky to dislodge any debris! If you lack the dexterity, pop it into a pot for a 3 minute boil to sanitize.

experiencing the xenuphora

If you’re looking for a conventional dildo, the Uberrime Xenuphora ain’t it. It’s nothing like “regular” dildos – but it’s not like other tentacle dildos, either.

My partner Buster (who tests all the insertable toys featured on this blog) was surprised at how easy the Xenuphora’s tip/head was to insert. It’s wider than the Teuthida’s tip and has an angular flare, but it’s squeezable and has a slick, glossy finish. As with any toy, some prep (relaxing into arousal and using plenty of lube) is key.

The bumpy texturing on this dildo is great. Like the Teuthida, the Xenuphora’s suckers provide a light pulling sensation as they bump and rub against you. The ridges are less exciting, but they still add a subtle massage to slow thrusts. Both create a lot of wet noises as you move the toy, as any good tentacle should.

Buster likes to use dildos like grinders sometimes, and says in their notes that “the suckers are more useful for rubbing off on than the ridges. The sucker nubs pop and drag really satisfyingly. But the ridges are all inset so it’s just a vaguely unnatural surface to grind on.”

Speaking of grinding… we were intrigued by the longer spikes on Xenuphora’s base. I was hoping that they’d provide a little nudge/tickle when fucking the toy. Sadly, they’re purely aesthetic – at least for Buster. Neither one lines up with Buster’s anatomy.

The Uberrime Xenuphora can be used with the suckers facing your urethral sponge (where the g-spot is located) or where the ridges are. With the latter position, the Xenuphora’s funky head curves upward and can provide some mild, tugging g-spot stimulation. (I say “mild” because the Xenuphora is pretty flexible; you won’t be getting Pure Wand levels of intensity from its curve.)

When thrusting the Xenuphora Alien Tentacle sucker-side up, the head can sometimes “catch,” folding the shaft over. When positioning the toy this way, Buster prefers to hold the base still and rock their body onto the dildo (instead of rocking the dildo into their body.) They like this method in general, because it allows them to bear down on the texturing.

Holding the base is surprisingly comfortable. The grooves in the base were sculpted by hand, so they’re a natural fit for gripping fingers. (Unless you have very small hands.) The squishy spikes keep your lubey digits from sliding around.

final thoughts on the xenuphora

This is actually the second iteration of the Xenuphora. Uberrime often updates their hand-sculpted models, incorporating feedback and ironing out kinks from prior molds. It’s one of the many reasons I love their toys.

I’m glad the changes were fairly minimal. The Xenuphora is as strange in use as it looks, and that’s exactly the way it should be. Unusual, unconventional – alien.

I wouldn’t suggest it as a first dildo because the design is less intuitive than, say, the Uberrime Splendid Small. This is not a dildo for someone keen on straightforward use; it’s for weirdos who want a bit of a challenge, a reason to take their time and feel things out.

If that sounds like you, the Uberrime Xenuphora Alien Tentacle can be found on SheVibe in the psychedelic swirls seen throughout this review. If you’re interested in a different color combination, find it on Uberrime’s own site.

Thank you, Uberrime, for not stopping me as I ran out of your studio with a box full of thieved goods. I consider Marco (Uberrime’s founder) a friend, but that doesn’t influence my opinions of their toys except to give me additional insight and appreciation for the artistry. I still hate the Amo (functionally, not aesthetically.)
