Several years into their marriage, the couple enjoys a good relationship but suffers from a complete lack of sex. One day, the wife's senior coworker from her massage job visits their home. As they chat, the couple opens up about their sexless marriage. Hearing their struggle, the senior suggests an NTR (cuckold) arrangement as a solution. The husband reluctantly agrees, and explains the situation to his wife. Intrigued, she decides to visit the senior's salon on a separate occasion. This marks the beginning of a new dynamic, setting the stage for an unfolding affair.
