Definition - What does Sumata mean?

Sumata refers to a form of non-penetrative sex in which a man is stimulated by thrusting his penis between his partner's thighs. The female partner can also move and rub the penis with her thighs and outer labia. Lubrication is often used during this practice to make it more comfortable and easier for the woman to bring the man to orgasm.

Kinkly explains Sumata

Sexual intercourse in exchange for money is illegal in Japan, but sumata is a popular service offered by many Japanese brothels. Other services that may be offered include fellatio and happy ending massages. Because it is a form of non-penetrative sex and considered safe, sumata, along with other forms of frottage, is legal in these facilities.
