Cock Milking

In the context of sex, CM can indeed stand for "Cock Milking." This is a term used to describe a sexual act or technique, typically involving manual stimulation of the penis in a way that aims to extract semen, sometimes without a full erection or as part of a specific fantasy or activity.

The "milking" aspect refers to the motion or action, similar to how one might milk an animal, applied to the penis to encourage ejaculation or to express seminal fluid. This term is often found in discussions within adult communities, pornography, or explicit content descriptions. It's a specific, descriptive term for a type of sexual interaction.
