That blood oath surely was important for the Vampire Race. I didn't know about it, nor had I heard about it before. But looking at this situation was enough to know that it was more important than I would've thought.
"Very well." I stood up and bit my thumb, letting my blood flow onto her palm, mixing with hers. It was just a drop, but I saw a very lustful expression forming on her face as her nose twitched slightly.
As soon as our blood mixed, she brought her palm to her mouth and drank them.
"Hnn~" A moan escaped her lips as her body quivered. "T-This… Delicious!" She exclaimed happily.
And at that moment, an unexpected notification arrived in my ears. This was out of my expectation, mainly because I did nothing.
But the windows floating in front of me were real.
[Blood oath has been made!]
[You need to feed her with your blood once a month, or she will go crazy!]
[Ding! Lucienne Brunet is dominated!]
