Check out cute-shukujyo. I've used it once and had Rya. Her ass is ridiculous and she knows how to use it. The only thing is she normally doesn't do foreigners but I sweet talked the hell outta the providers into talking her into giving me a chance.
I was a pure gentleman so hopefully that opened some doors for us gaijins
She said she was turned off by an aggressive French guy who was extremely rough and tried to force BBFS.
If she doesn't work out then there are a bunch of other girls on there they are thick as well. I hope this helps.
I too love thick bottom girls.
I used to put in serious work into Ryo of AM way back in the day.
Ryo got a belly but you don't see it when you're drilling her doggy.
