Anne, who became a widow at the age of 25, receives a surprising request.The request was for the sons of princes and aristocrats to be taught the ropes. She seems to have been chosen because she is a young widow with experience, but she has been married to an old marquis for about 10 years, and she is actually still a virgin! 　However, in reality, Anne, her reincarnation, uses her knowledge and experience gained in her previous life to come up with a secret plan called ``Sex Techniques Lessons''! But (but) for some reason, even her older son-in-law, Elliott, was attending that class... The young women on the other side, with serious faces, bring out dildos and demonstrate sexual positions, which makes the novice boys, mostly teenagers, blush all the time - and even Elliot (who is actually a virgin) is acting strange! ? 　Her innovative classes become popular on the streets, and unexpected developments await Anne one after another.
