One of the best nipple toys we've seen ages! The vibrating cup fits over the nipples and has a noduled stimulator at the tip to tease and stimulate, but there's more!
The cup also has a mini pump attached that you can use to create a vacuum that keeps the cups in place and turns up the tease factor to max. Great value twin pack.
Comes with eight watch-style batteries, enough for both of the teasers.
