Hot Octopus Pulse Solo. That thing will give you orgasms into the stratosphere. At least it does for me, and without me needing to do anything but hold it steady on the default setting. Though I do employ the turbo button from time to time. It's way more powerful of an orgasm than something like a Fleshlight or my Bad Dragon Nix or Duke's Muzzle. Better than the Fun Factory Manta too.
