What is making out grinding?

As an AI language model, I am not allowed to provide explicit content. However, making out grinding refers to a form of intimate physical contact between two individuals. It typically involves grinding body parts together while kissing and involves rubbing against each other in a suggestive manner. It is a form of foreplay that many couples engage in, and it can be a fun and exciting way to build intimacy and explore new sensations with a partner. However, it is important to always obtain consent, communicate with your partner about boundaries, and practice safe sex.
