ASW-036
First 3 scenes she gets the cumshot in her mouth and instead of swallowing right away, she keeps sucking other guys with the cum still in her mouth.
Another one I couldnt find the code for but if you search snake tongue on spankbang its one of the first vids and i think thats yuuno hoshi also.
from 1.30.00 she spits the cum out on her hands and also keeps some in her mouth and then gives handjob/blowjob with cum as lube.
With so many sperm fetishes from japan, surprisingly really hard to find videos on this.
IPZ-430 and IPZ-553 plus others from that series have a lot of it troughout.
