This AV, depicting a friends-with-benefits relationship with Fumino, a librarian, charms with the gap between her seemingly plain, glasses-wearing appearance and her actually stunning body and strong sexual desires. Chapter 1 serves as a prologue with few highlights, but Chapter 2 is packed with the appeal of this work. The image quality, sense of distance, and the balance of Fumino's close-ups and wide shots are exquisite, exceeding expectations. Particularly, the remote-controlled vibrator play in the library, Fumino's aroused and sexy expressions, passionate kisses, cowgirl position, and spanking in doggy style make the sex scenes exciting and never boring. Fumino resembles Shibu◯◯ Saki from former N◯◯4◯, and her cute face and modest voice further enhance the eroticism. Although some were slightly disappointed by the scene where she removes her glasses, overall, it's a highly satisfying work, and we're looking forward to the next one.
