Lucía and Sex
Idea suggested by Lucía.
Have you seen Lucía and Sex? Regardless of it being quite a recommendable movie to watch for its spiciness, we propose an erotic game taken from one of its scenes:
She lays her boyfriend down on the bed with his eyes blindfolded and starts placing different parts of her body on his lips for him to guess what it is... As you can see, it's a more than recommendable suggestion to try out.
