I watched the new work by Momozono Rena, a full-length first-person masturbation assistance humiliation title where you train the busty beauty office lady Rena. The story starts from her student days, where her homeroom teacher forcibly subdues the delinquent girl and begins training her into a masochistic beauty dedicated to his pleasure ejaculation.

First, regarding immersion as a first-person work, the male actor's voice was a bit distracting. If it's promoted as first-person, removing the voice would allow viewers to immerse themselves more easily as the protagonist. Especially in the final chapter, which includes a cheating element, the presence or absence of voice is a crucial factor for realism. However, the actress Momozono Rena's acting skills are excellent, making it a highly practical work. With a bit more focus on immersion, it could have been an irresistible masterpiece for first-person enthusiasts.

Next, while some point out that the dialogue in the drama parts is awkward, given the masochistic training genre, this isn't too bothersome. Instead, Momozono Rena's charm—petite with a youthful face yet a voluptuous busty body when undressed—enhances the abusive situations. Among her works, this stands alongside 'Called a Delivery Health' as a top-tier documentary-style piece, a must-see for fans.

Personally, it was my first time watching Momozono Rena, but I can confidently say this is her best work to date. Her face, body, and masochistic performance are top-notch, gripping the sadistic heart intensely. Scenes like her facial expressions during oral, breast-bouncing cowgirl position, and spanking doggy style are full of highlights, with too many exciting moments to count.

Seeing Rena's cum swallowing scene after a long time deserves a perfect score. Overall, it's a highly practical work that blends a strong setting with the actress's appeal, showcasing the potential of first-person productions and raising expectations for future works.
