A new app is set on teaching your tongue a few new tricks when it comes to pleasure in the bedroom.
Using your own touch screen, Lick This features three interactive tongue exercises to improve both skill and technique.
One test has users flick a light switch using their tongue, while another has a crank that can only be turned by licking the screen effectively.
