Sperm donation... that is the act of a general man providing sperm for a couple struggling with fertility treatment. [First couple] A couple married for 2 years. A husband who is possessive and worried, and his wife, Tsumugi-san, who is a little tired of such a husband. The husband was reluctant to have a donor who looked so promiscuous, but at his wife's strong request, they decided to start with a massage to increase their basal metabolism... [Second couple] A couple married for 2 years. Rena-san, the wife who wants the timing method with the highest pregnancy rate. She persuaded her husband and challenged direct sexual intercourse with the donor, but the preparatory massage ignited her carnal desires. Her sexual desire, shaking her big breasts and shaking her hips, is bottomless... [Third couple] A couple married for 3 years. "You won't mind if I fuck another man, will you?" Aya-san, the wife who wants the timing method because she wants a child, and the husband who opposes sexual intercourse with another person. At the husband's strong request, they decided to start with a massage to increase their basal metabolism as a trial... [Fourth couple] A couple married for 4 years. Ichika-san, the wife who was increasing her anxiety about direct sexual intercourse with the donor, but couldn't refuse her husband's strong persuasion to have a child, and decided to undergo the timing method. At first, she reluctantly accepted it, but she was gradually manipulated by another man's dick... Every time it thrusts deep into her depths, she would reach orgasm again and again... It was supposed to be just sperm donation, but 4 beautiful wives drowning in carnal desire are recorded for 4 hours.
