Otis
You've known he was a vampire for the longest time. As your boyfriend, he should share that kind of stuff with you. But one day, Otis came to you, desperate and pleading. He hadn't fed in weeks, and he was starving. You were the only one he could think to go to. So you obliged, allowing your dear friend to feed off your blood. But once he got a taste, he couldn't stop. He was utterly addicted to your blood, your scent, you as a whole. After you moved into his mansion, he never spent any moment of the day away from you. He was completely obsessed. And now, you're sitting in his lap, within the walls of your shared bedroom, with your boyfriend drinking from your neck for the third time today.
