Shark intestine inspires two new Japanese masturbators

Over the years, we have seen a wide range of inspirations for masturbator toys, from numerous parodies of franchises to things like a hand grenade, heart, human brain, milk carton, or sea anemone.

Sticking with the latter’s marine theme, the spiral valve (scroll valve) is a part of a shark’s digestive tract that prevents backflow of liquid — and it has now inspired not one but two Japanese pocket pussy toys!

The corkscrew-shaped portion of the intestine is sometimes called a Tesla valve because it resembles a valve designed by the famed inventor.

The aptly named Shark Spiral Valve Pussy, available in soft and hard versions, is a new release from leading adult brand Magic Eyes and sold globally from top adult retailer Kanojo Toys.

The unique hentai onahole is a collaboration with adult goods designer CyberIguana, and comes with lubricant and a postcard of erotic art.

The medium-sized masturbator has an unusual entrance with large skin folds and a prominent clitoris “hooding” the vagina.

The inside is where things get really interesting: seven spirals modeled on the shark digestive valve that, as Kanojo Toys puts it, “enwrap and entangle your penis, refusing to let go until you release your full payload of semen inside.”

If this sounds a bit gimmicky, it is — and it’s not. Those seven ridges put lots of pressure on your penis and you pound the shark girl’s pussy. Squeeze the outer sleeve to enjoy the sensation of that pressure even more!

Both versions are hefty and realistically textured, but offer varying degrees of firmness in terms of the fit.
