YRMN-029 - Will a plain girl surrounded by two sluts turn into a slut at a group date? Sakura

*The big-breasted Ai Tsukimoto is more erotic than the main character's daughter as she gives a blowjob while the girl is watching. I'm playing it to see Ai-chan.

Sakura-chan = Mochizuki Sakura (Kuramochi Rin), Big-boob Bitch A-chan = Tsukimoto Ai, Slender Bitch M-chan = Kubozuka Miina. They hold a 3-on-3 mixer. Things get steamy at the bar, leading to an orgy at home, and later, 1-on-1 sex at a hotel. Tsukimoto Ai and Kubozuka Miina both did a great job playing the 'bitch' roles. It was better than the previous installment where the main actress was overshadowed by three sluts. If I had to nitpick, I wanted a bit more screen time for the main actress's erotic scenes. Also, I wish the other actresses had joined the male actor in going after Mochizuki Sakura during the orgy scene. Kubozuka Miina did a little bit, but I wanted more.

*An experimental documentary-style film to awaken the plain girl Sakura to sex. It's a flow, and since Sakura is mainly photographed, the person who set it up is a slut friend. The scene where two people are having sex is almost out of frame! At the very least, I'd like them to devise better angles until the plain Sakura awakens. In the end, Sakura becomes aroused and becomes wild, but the H scenes are mostly just Sakura, so it's a bit of a shame that we don't get to see much of the H scenes with the two sluts!

Does anyone know who the cast members are in this? I'm trying to find the name of the actress with the largest breasts.
