Get the discreet bullet vibrator that you can pass off as a tiny remote if need be...
The travel-friendly Massage Bullet Vibe from Fun Factory has five intensity settings and a powerful motor all packed into its little, rounded form. Discreet enough to carry around in your purse, but strong enough to knock your socks off. Plus given it's compact form, it's packing all the vibes into a tiny point for really intense clitoral stimulation. Or anywhere else stimulation for that matter.
If you want it even more intense, just add a touch of your favourite lube to the toy or your body - and given it's made from a body-friendly thermoplastic you can even use silicone lube for the long lasting slick. Or shower play.
Once you're done, clean your toy with anti-bacterial toy spray and rinse with warm water. If you're using silicone lube you may want to use a mild soap first. Let your bullet vibe dry fully before storing it away for next time.
