A man provides his sperm... This is an act where general men offer their sperm for couples struggling with infertility treatments. In this case, we have a married couple celebrating their third wedding anniversary. They both work hard and complain that they don't have enough time together due to their busy schedules. The wife, Reimi, wishes for a child but struggles because she can't find the right moment with her husband. As she receives the sperm donation, she undergoes a massage which ignites her sexual desires. Eventually, she gives in to her lustful urges and engages in passionate intercourse with a stranger, forgetting about her husband and indulging in pleasure-filled sex.
