I actually watched this work titled "Hey, can I stay over today??" and was immediately drawn into the story by the unique setup where a sister suddenly shows up at home, begging to stay overnight. The everyday scenes, like going shopping and asking her to house-sit while I go to work, add dramatic tension to the later developments. The protagonist's inner conflict while watching the sister sleep soundly is portrayed realistically, and seeing her grown into a voluptuous adult beauty heightens the excitement. The more he tries to restrain himself from thinking dirty thoughts, the more his erect penis becomes prominent, amplifying the psychological tension and making it highly engaging.

With four actresses appearing, each has a cute face and an alluring body that fully arouses excitement. The work's strength lies in its focus on intimate scenes rather than a complex plot, featuring numerous erotic moments that fans will find irresistible. Personally, I noticed that Aise Ruka resembles Eriana Iwata, a Nippon TV announcer, but Ruka-chan has more potential for growth, making her future performances something to look forward to. Overall, this piece skillfully depicts the boundary between the ordinary and extraordinary, creating an addictive quality that hooks you from the first watch.
