This is a serious NTR series from S1, featuring Aoi Tsukasa in the lead. While the premise is questionable, her beautiful figure and hip movements are captivating. However, some viewers find the storyline lacking in substance. There are calls for improvements in character development, atmosphere, and overall progression. On the bright side, the scenes featuring cowgirl and face sitting are refreshing, with her large, fair bottom receiving particular praise. While there are voices hoping for internal ejaculation scenes, some opinions suggest that the overall eroticism feels slightly underwhelming.
