Nurses who lick their lips at husbands who visit for fertility treatment one after another. Husbands visit for diagnosis after enduring masturbation for two weeks for their beloved wives' fertility treatment. But the nurses here have a hobby of getting such husbands' accumulated sperm for free. In other words, it's a limited-time NTR during the fertility period. "For your wife, please release a lot inside me," "There are plenty of fresh and energetic sperm," "Since collection is necessary, if the sperm comes into contact with the air, it will affect the test results. Please release it into the vagina without leaking a single drop."
