A lap dance is when someone, usually a woman wearing sexy clothes, dances in front of someone else while sitting on their lap. The person being danced on usually sits on a chair and the dancer moves their body in a seductive way while rubbing their body against the other person. It’s a special kind of dance that some people enjoy watching or taking part in at certain places like clubs or private parties. It’s important to remember that a lap dance is for entertainment and not for anything else, and it’s only allowed for adults.
