Tantus Cush O2 Dual Density G-Spot Dildo Rose Quartz

The Tantus Cush O2 is a curved, dual-density silicone dildo shaped for G-spot play, here in Rose Quartz. Its graceful curves press forward where you want them, and the silicone is soft outside around a firm “muscle core”, so it gives a little when squeezed and then resists.

At 7 in long and 1.75 in in diameter it is a medium-to-full size. It is harness compatible and, Tantus says, safe for both vaginal and anal play, and like all Tantus silicone it can be boiled or put in the dishwasher.

From Tantus’s product description.

1. Warm up first; the G-spot area responds better when you are already aroused.
2. Use plenty of water-based lube.
3. Insert a few inches with the curve facing your belly button.
4. Rock or press the head forward rather than thrusting deep.
5. In a harness, the curve faces up toward the front wall for a partner.

What does dual density mean?

The Cush O2 has a soft outer layer over a firm inner core. Squeeze it and the surface gives, then the core pushes back, which Tantus says gives a realistically familiar feel.

Tantus lists 7 in long and 1.75 in in diameter.

Can I use it in a harness or for anal play?

Yes. Tantus says it is harness compatible and safe for vaginal or anal play.

Can I boil it?

Yes. Tantus silicone is boilable, bleachable and dishwasher safe. Use water-based lube rather than silicone lube.
