OKYH-026 - High school girls on a field trip in Hakone, want to join me in the men's bath?

Yukina is cute and professional, and the game was on the hardcore side, which I liked. Does anyone know the actress's name?

It's a duo performance, and 'Yukina' leaves a good impression because she's cute and friendly. It makes sense that she was the one who did the mouth-shot during the ring toss mission. On the other hand, 'Aika' isn't particularly pretty, but more than that, she was unfriendly and left a bad taste in my mouth. She could have at least smiled, but her responses were short throughout, and she was barely reactive during the brush mission. I really have to wonder why she was even there. If it were just Yukina, I would've given it 5 stars, but I'm docking points because of Aika.
