Nozomi, Isski Sae, Nami Watanabe are patients at a local fertility clinic. The pervy doctor meets them, then lines these ladies up to inspect their vaginas- up to and including licking their labia and inserting his fingers into them- to taste test for the proper time to fertilize them. While there is pleasure for the ladies, it's the pervy doctor who gets the most pleasure from being able to grab any pussy he wants.
