"This will be my first time drinking blood directly from a body. But you are now used to it since Jane sucked your blood many times."
"That reminds me of the promise."
"What promise?"
"You are not allowed to drink anyone's blood other than mine."
Rias squinted her eyes and asked, "What type of promise is that? And did Jane agree to it?"
"Yes."
"Really?!" she asked with a surprised look on her face.
"Yes."
"Hmm." She hummed in wonder and said, "Okay. I don't actually drink blood. Maybe once a month or something since I don't feel an urge like the other vampires."
Rias licked Rudy's neck and whispered, "I will be digging in."
"Wait, before you do it. Can I do it on you too?"
"What do you mean?" she asked with a puzzled look on her face.
"Can I mark you too?"
Without replying, Rias buried her fangs into Rudy's neck and sucked his blood.
