Mahiro, better known online as maheee, is a rapidly rising streamer loved for her adorable face, relaxed chats, and gaming broadcasts. Her shut-in, unemployed adult brother is her complete opposite; after years of viewing her sexually, his jealousy turns into bitter resentment. He exposes Mahiro to the entire world by creampieing her during a livestream, then forces her to keep servicing his sexual urges afterward.
