The AV work I watched this time features a thrilling scenario where a man wearing a chastity belt is seduced by his live-in girlfriend's older sister, Rin, with Hachimitsu Rin's alluring performance shining through. Rin, with her sexy charm and excellent figure, perfectly fits this devilish role, naturally exuding appeal in the plot where she toys with her sister's boyfriend. The work is 150 minutes long, offering ample time to enjoy, but the content feels somewhat thin, with many unnecessary scenes. Specifically, the post-insertion time in the intimate scenes is too short, resulting in poor overall balance. In two intimate sequences, the post-insertion lasts only about 10 minutes, which lacks the impact expected of an AV and disappoints with few climax moments for fans. It's hard to call it a work worth keeping, as I had hoped for more intense developments.

However, the scenario setup itself is perfect, with the concept of a man under abstinence being managed through titty-fucking by the sister being highly appealing. Hachimitsu Rin's titty-fucking scenes are full of intensity, drawing viewers in effortlessly, but I feel her potential isn't fully utilized. If there were more varied torment patterns, the work would have gained more depth. Personally, I think it would be better remade with an actress specializing in titty-fucking, but this theme suits my taste, and I'd definitely buy any sequel. Overall, fans of Hachimitsu Rin might find it worth a watch, but those seeking richer content might feel it falls short. I have high hopes for future works.
