The Plasmoid was first discovered by interstellar biologists aboard the Drift S5, a derelict research vessel adrift near a collapsed wormhole. Among the ship's remaining organic samples was a dormant Moltherian—a creature whose exoskin pulsed even after death. Upon contact, the specimen reacted to human warmth with rhythmic contractions and sensory feedback unlike anything in the known galaxy.

Reverse-engineered using non-invasive replication protocols, the Plasmoid is now one of the few legal xeno-erotics licensed for human pleasure.

Sex doesn't always involve penetration which is why we created this unique toy for external stimulation. 

These non penetrative sex toys are design for all of your rubbing desires. With over 80 individual nubs to caress your most sensitive parts, this Rubbie is sure to be the best bumpy ride you've ever had. Each Rubbie comes with two black (2.5 ft) nylon straps fitted with loops for easy adjustment.

Strap a Rubbie to a thigh or forearm for fun with your lover. Playing solo? Strap your Rubbie to a pillow grind away. Take the straps off and roll into a tube for an easy male masturbator. Strap it to a hand for incredible external sensations for any gender. Also works great just on the side of the bathtub ;)

Best used with a small amount of lube to keep things slippery.

Carter W. ★★★★★

Wasn't sure what to expect from a grinder tied to some derelict wormhole research ship, but it chews through everything I throw at it without clogging. The build feels solid in hand too.

Lily ★★★★★

The backstory about the Drift S5 really drew me in, and I'm glad the build quality lives up to the lore—it feels sturdy and precise in hand. Grinding is smooth and effortless, exactly what I needed for my setup.

Richard I. ★★★★★

The lab-grade casing on this grinder feels incredibly solid in the hand, and the chamber depth is perfect for a proper session without constant packing. It’s got that slight weight that makes you trust it, and the thread action is smooth as butter right out of the box.
