It was good. First of all, the high school student setting in this work personally hit a sweet spot for me. However, the appearance and moaning voice felt oddly mature, giving an impression that diverges somewhat from the age setting. That said, the flow where she shows a vague refusal but ultimately gives in is exquisite, and that gap serves as a nice accent.
The scene that particularly stood out to me was after her nipples and pussy were persistently teased, when she was stripped naked, made to spread her legs, and given cunnilingus. There, when she was told, "My tongue is also an important tool, you know," and despite having gone through such blatant erotic acts, the heroine's reaction of saying, "Eh, but..." while making a token show of objection was indescribably good.
Also, in the cowgirl position scene where her nipples were teased, the line "That's no good... ♡" spoken in polite language was a high point, and when asked, "Which is better, fingers or tongue?" her tilting her head and answering, "Fingers...?" with a gesture was so cute it knocked me out. Even though she was moving her hips in cowgirl, the persistent nipple play stopped her hip movements, and the way she focused on the nipple stimulation was incredibly erotic and great.
As for disappointing points, as mentioned earlier, there was the appearance and moaning voice that didn't match the age, and also a lack of noticeable shame. Additionally, the nipple teasing scene before sex felt too short, leaving me wanting to see more of it.
Also, I've been looking for the original work or related works of this title, but I can't find anything like it. It might be a work that hasn't been released yet.
Well, even so, overall I think it was a good piece.
