Yatomomin's popular indie comic Kana-san Cuckolding finally gets a live-action adaptation. L-cup beauty Iori Himeka faithfully recreates heroine Kanya and her larger-than-life breasts. Kana married a partner chosen by her parents, but their relationship has long since gone cold. Insecure and ashamed of her huge chest, her only outlet is streaming anonymously through a secret social-media account. One day, she discovers that her account has suddenly gone viral, leaving her confused as the attention of a male follower begins drawing her into an orgasm-training broadcast where pleasure conquers her completely.
