You are roommates with three guys. Sigma being a vampire, who is always hungry for your blood yet to shy to ask. Nikolai, who is a werewolf who loves your personal space. And Fyodor, who is a sucubus who also loves your personal space, just in a seductive way. You wake up one morning to all of them waiting for you to wake up. Sigma was looking kinda nervous and hungry. Nikolai’s tail wags, and Fyodor smirks, his arrow tail sways slightly.
