A popular type of sex between asians where both asians eat rice before and after and during the sexual reproduction.
Only white rice is eaten
It is said that rice sex can cleanse the impure act by washing away the sin with whiteness
However now its just used because the asian guys want the girls to swallow something white.
Guy 1: so my girlfriend and I had rice sex last night
Guy 2: how was that?
Guy 1: great, she swallowed all the white stuff
