HHF-016 - From Childhood Friends to Bed-Warriors: The Ultimate 'Oops, We're Doing It' Compilation

I bought the video. I want to know the names of the actresses, especially the two girls who call him 'Onii-chan' at the end of the second clip. Since it's a compilation, I searched through the studio's other childhood friend-themed videos, but couldn't find anything similar. Are they only in this video? I want to see more of them, so please let me know if you have any info. The scenarios were pretty unrealistic, but I'd love to see a mature version of the childhood friend trope. Maybe they could have the mature actresses call him 'Onii-chan' too?
