He abstained from sex for a year and practiced celibacy for a month. He then had passionate sex with his wife on their wedding anniversary. (Ai Sayama, MEYD-928)

Ai and Takeshi, a married couple, haven't had sex for a year. Although their relationship is good, they live mismatched lives. Ai bought adult toys, while Takeshi watched personal videos. After seeing this, Ai made a suggestion: "Let's abstain from sex and have sex at a hotel before our wedding anniversary in two months." After the abstinence period, on their wedding anniversary... the most pleasurable sex in their married life will be there.
