I actually watched this AV work, and it strongly emphasizes a sibling setting, depicting a sister witnessing her brother masturbating while watching AV at night, with both gradually becoming aroused. Particularly, actress Nagisa Mitsuki, known for her beautiful face and buttocks, appears, and her cute face gradually descending into depravity is very erotic and exciting. Her moans are also adorable, making her performance irresistible for fans. The work is in an omnibus format with four actresses, each playing a sister role, but the first and second actresses were especially impressive, with mostly soft interactions that naturally built sexual tension. On the other hand, the fourth actress's scene involved a more forceful approach from the brother, making the content slightly intense and feeling a bit unbalanced with the other episodes. Overall, there are scenes ending with creampie, incorporating the sister's resistance in a soft rape style, and the setting of siblings sharing arousal is interesting, but it feels too constrained by the title, leading to similar developments and a desire for more variety. Still, the actresses' performances and visuals are highly commendable, and fans of Nagisa Mitsuki in particular will likely be satisfied.
