Completely unobtrusive, both in size and volume, the discreet little Finger Friend vibe from Doc Johnson's Oralove collection presents an absolutely perfect accompaniment to oral sex. 

Slipping securely over a finger, a thrillingly nubby textured jelly sleeve surrounds a tiny vibe that switches on and off in a flash. The ensuing stimulation isn't overly intense, just a nice, unrelenting buzz that, combined with the pleasures of the sexual scenario of choice, fits as naturally as could be. 

Though technically considered a one-time use toy (the non-replaceable  batteries will power the vibe for about 30 continuous minutes) the Friend could last through a few sessions. Not recommended for use in water.
