Even though she disliked it, she kept licking and swallowing it with a lewd and delicious slurping sound. (Morisawa Kana, DASS-329)

Shinichi has a beautiful and gentle wife, Kana. His junior colleague, Okada, secretly harbors feelings for her. One day, Okada hears that Shinichi is suspected of embezzling company funds, so he launches an investigation on his own and uncovers irrefutable evidence. Using this as a pretext, Okada threatens Kana and forces her into his service.
