Man, one of my favorite movies with her is an NTR one, and she's wearing a yukata there as well, same as here. I didn't expect it would be that one
The cumshots are fake,

MTYD-003 (it's based on a manga, and there are actually
several adaptations of it, which is very rare, as I understand; I mean, I cannot think of any other case where the same manga was made into several JAV with different actresses*).
