The unique-looking Break Insert Onahole by Japanese adult toys makers Prime is one of the most intriguingly designed masturbators we've seen in a while. Part steampunk costume accessory (check out the gauntlet on the character on the box), part organic tentacle-weapon, the intricate edges and sections on this hefty onahole offer a flesh-like thick skin to knead and grip as you explore the inside.
The inner passage itself is just as special as the exterior, featuring what Prime calls a "Twinkle Rubbers" design. From the nub nest entrance you are squeezed along a tight tunnel to the first opening. You are barely through this when you are next pushed into yet another, tighter short tunnel... before exploding into a womb-like nub bed, with a final chamber to complete the sensation.
