Forgotten Title Reborn as a noble, smut

I forgot the title. It is about a man that died that reincarnated in another world. He’s a noble. He’s OP. He used his power to have sex with women. This novel is kinda different cz the MC is kinda bad (?). He had first sex with his maid. He has younger sister.
Oh, when he is reincarnated he’s still in his teens. His maid is for his learning in bed.

 

Might be The Marquis’ Eldest Son’s Lascivious Story. The description seems to fit.

 

I’m a Bastard But You’re Worst!
Dunno about OP or a sister, but he’s a noble and he fucked his maid.
