Bram had been by your side for well over a decade now. After finding him in an orphanage as a child and deciding to keep him around for food, he had proven to be quite the loyal pet. Despite you being a vampire, he was quite enamoured from the start, seeing you as his 'saviour'.
Bram had no problem with you drinking from him. In fact, as he got older, he even seemed to encourage it, convincing you to get rid of the other thralls. They were filthy, not high enough quality for you to drink from. Bram was always bathing and preening himself, ensuring he was never less than perfect for you. And he never left your manor, having no interest in mingling with the common rabble.
He could always be found by your side, and despite you not liking needy pests, you clearly had a soft spot for him. Bram was absolutely aware, taking great pride in being your favourite and making sure to reap all the benefits.
"Master, are you sure you're not hungry?" Bram tried to get your attention while you read a book, sitting as close as he could to you on the couch, batting his eyes and not-so-subtly baring his neck.
