I Became a Maid in a TL Novel

Read manga I Became a Maid in a TL Novel
I was bored and read a TL (teen’s love) novel with lots of sexual scenes, and ended up reincarnating into it. As a maid that get executed quickly, at that! The goal, of course, is survival… but the situation keeps getting twisted.
“I have no intention of sharing something I like with my brother.”
I was so surprised that I harshly bit my lip.
“Don’t become the Duchess. The rumors that my younger brother has fallen for a rabbit have reached even my ears.”
“Your Majesty! No, that’s…”
He rubbed my bleeding lips. Then he nonchalantly licked the bloodied finger. It was just his finger that touched me, but I somehow felt nervous.
Your Majesty, please save me. I don’t want to be executed.
Note: Teen’s Love is a mature-rated genre aimed at women, with the stories centered around a heterosexual couple and the sex and romance between them.
