Uchi no Ojou-sama no Hanashi wo Kiite Kure - Akuyaku Reijou Kouryaku Kiroku

Crow, the butler of a villianess, coincidentally realizes that the world he's in is that of the otome game he had been playing in his past life. After carefully re-examining the situation he's in, anger begins welling up inside of him because of how poorly he's been treated by the haughty, arrogant, selfish, and prideful young lady he serves. But after deciding to exact revenge on her in a rather sexy way, he finds that she's a lot more of an easy woman than he thought... This is the story of how, after being reincarnated, a butler lustfully tries to break his lady, but ultimately brings her true happiness.
