Miboujin Anne no Neya no Tehodoki

Anne, a widow at the age of 25, receives a shocking request: to "teach the arts of the bedroom" to princes and sons of nobles. She's chosen because she's a young widow with some experience, but despite being married to an old marquis for about 10 years, she's still a virgin! However, Anne is actually a reincarnated person, and she uses the knowledge and experience from her previous life to conduct "classes on sexual techniques"! But, for some reason, her older stepson, Elliot, also attends the class... As the young woman, with a serious expression, brings out dildos and demonstrates positions, the innocent boys, mostly teenagers, blush profusely—and even Elliot (who is also a virgin) starts acting strangely! This unconventional class becomes popular, and unexpected events await Anne one after another—? A hilarious and thrilling erotic comedy, now surprisingly adapted into a comic!
