NTR: I became a noble?

[Mc takes consent from Woman not their husband] [Mc doesn't want to NTR every guy. He only makes their wife cheat for sex.] [Making friend's mom fall......is one of his big dreams.] "I like married women and there are so many noble women out there..." A horny Otaku from Earth gets transmigrated as an old Viscount. His lifespan is depleting too quickly due to an injury. Fortunately, there is a Ying Yang technique which can increase his lifespan. "This man has been single for his whole life and never touched a woman? WTF!!" Otaku is shocked from the Viscount's dry life. "I do have the maids, right?" [MC likes married women] [Netori, Cheating, Blackmail]
