Mesukatsu [female activity] [noun] 1. An activity that seeks a relationship based solely on the body, without seeking anything in return like sugar daddy dating. 2. A moment between two people who don't have the affection of a mistress, but have the potential not to be experienced with a sex friend - two people who don't know each other's names or backgrounds, but can't forget the sight of each other's bodies. A stimulating encounter between a woman with a mellow body born and raised as a sex toy and a man who knows all about how to turn a woman's whole body into a sex organ.
