Wikipedia definition
3. Sumatais a Japanese term for a non-penetrative sex act popular in Japanese brothels. Sumata is a form of frottage, performed by a female sex worker upon a male client. The sex worker rubs the client's penis with her thighs, and labia majora. The goal is to stimulate ejaculation without penile-vaginal penetration. This activity circumvents the Anti-Prostitution Law of 1956, which prohibits sexual intercourse for money.
