The story features miru seducing her sister's boyfriend, starting with bold approaches in a beauty salon, highlighted by sensual scenes where she presses her breasts and uses dirty talk to entice. Her cute appearance, combined with beautiful breasts, fair skin, and a slender body, is fully utilized, with well-paced sex scenes showcasing top-notch hip movements that are perfect from any angle. This work emphasizes the hidden element of secretly tempting the boyfriend, reminiscent of scenes from the previous work 'Inside the Long Skirt,' and the latter half sex reaches maximum excitement for a great release.

However, the dual-screen setup is small and hard to see, with unclear director intentions. miru's works are often easy to enjoy quickly, but her consistent personality lacks freshness. Still, the eroticism is overwhelming, maintaining an appeal that doesn't get boring. The covert handjob in the beauty salon and bold play in the shadows are excellent, but subsequent scenes fail to surpass the initial chapter, with play feeling somewhat bland and French kisses average. The male actor's lack of strength is also noticeable, making it a work with overall balance issues.
