Ultra-tight modular silicone masturbator — Iku Tighter

The most extreme tightness in the IKU range. The serrated star-shaped central orifice forces its way in with each entry — once inside, the ribs that radiate towards the bottom envelop the penis along its entire length, leaving no room to spare.

The tight orifice that bites at the entrance

The center of the sleeve forms a star with soft points — about two centimeters at rest, which spread apart as you push. The passage of the glans becomes the event of each back and forth: it resists, it yields, it closes behind. For guys who edge solo, this is the friction they are looking for.

The caressing ribs

Inside, micro-ridges emanate from the center like spokes of a wheel and descend to the bottom. Once the penis is engaged, each rib stimulates a different point — glans, frenulum, base. The stretching of the silicone shows you the skin returning to its place: you see the empty effect after each withdrawal.

Medical grade silicone

The sleeve is made of medical grade silicone, phthalate-free, silky to the touch and warms up in the hand even before the first thrust. The rigid shell surrounding it maintains its shape — no collapse when you squeeze, the sleeve stays in place even if you thrust quickly. Fun Factory manufacturing in Bremen, 25-year warranty on the shell.

Under warm water, it heats up quickly

The silicone is resistant to showering and washing. Slide it under the jet to warm it up, generous lube on the glans, first thrust — you feel the warmed silicone yield. Solo after sports or long Sunday edging: the tightness lasts as long as you push, and you finish when you decide.
