Yes it’s actually a thing, personally I prefer to just call it: sucking your partners fingers.
Why? Because it is really fu*king hot.
It is fun, it feels good and it could increase the sexual tension and excitement during foreplay. The best thing is you can do it anywhere and at any time so it’s a great part of foreplay that can start already before you get home inside the bedroom. If you are sucking on the fingers on a co*k owner I’m sure it will send signals to other body parts with pleasure and work wonders as a teaser of what might come later.
Lick, suck, kiss, drag your teeth against the skin, bite gently, lick or suck food of the fingers… never ending options as always when it comes to foreplay!
Make sure their hands are clean and go all in with confidence!
Go all in and and do it with passion. Turn yourself on while you are doing it!
Be playful, tease, see what they respond to, look at them and don’t forget that any kind of sounds or sex noises are always welcome and often add pleasure to the experience.
You can even grab their wrist and drag their hand towards your face and slide the fingers over your lips, jaw and neck before you go back and keep sucking.
Such a simple act and yet so much pleasure and arousal to come from it.
Enjoy
