IENE-561 - Friendzone Breaker: Testing Their Chastity in a Mixed Hot Spring

Does anyone know the name of the third actress who appears? Please let me know if you do.

I liked the 1st girl, Naoko (Kana Yukimoto), the 2nd, Sayaka (Aoi Shirasaki), and the 4th, Yui (Nanase Otoha), as they are my favorites. Is the mosaic on the male actor's face really necessary?

Overall, the concept and content were very good. However! The staff (director?)'s voice is so loud that it ruins the whole production!

Does anyone know the name of the busty actress who appears first?
