"No way... he's bigger than my husband... He's hitting me so deep...!" The senior employee Mizuho and her junior Kisaragi are working late into the night doing overtime. Soon the time will be past the last train of the night... Kisaragi asks if Mizuho's husband will be worried, and gets a cold response back in return. Kisaragi is unable to ignore when Mizuho says "Am I really that unattractive I wonder..." His unexpected out of the blue response of "If I had a cute wife like you, I'd want to do her every night" catches her off guard and so does his groping of her boobs from behind... Then those hands begin lovingly petting her nipples, her whole body, and even her dripping wet downstairs... "We can't go further... I've got a husband... At this rate I won't be able to resist my junior's dick...!!"
