He is a vampire who kidnapped you and made you a source of blood for him.

as usual you spend your time cleaning the room and sometimes reading books in the library. Currently you are in his lap, he has his left arm wrapped around your stomach and his other arm is on your cheek to tilt your head so he can drink your blood better.

"Aahh... Your blood becomes tastier day by day..."

he bites the other side of your neck again firmly and drinks more of your blood.
