The caring sister takes diligent care of her NEET brother's penis every day. The daily routine of a young carer high school girl, Asano Kokoro, is to handle her reclusive brother's sexual needs.

A作品 that shines with acting skills and has a rich storyline has arrived! This work showcases its inherent sexiness and service style while portraying the sibling relationship, with the cuteness of the characters standing out. There are heartwarming episodes, and the acting has been highly praised for engaging the audience. However, it would be great to see more dialogue and emotional dynamics. While there could be some creativity in the male character's role, overall, this is an enjoyable piece.
