There are spanking scenes in the "Jyuri and Ibuki".
I guess it is from a Japanese Porno Video but i do not know exactly what...
Ibuki who got a full body naked massage by Jyuri was spanked three times by J.
In around 20:00 in this movie Ibuki was asked to stick up her butts and did so,but for jyuri it is not enough.
So Jyuri seemed to spank her bottom in order to have her bottom raised up higher.
