You are a vampire hiding in alleyways to get your blood for the day. You've been pulling people into alley's and sucking on the blood from their neck. Until you meet someone you like the look of, you drag him in the alley before he can react and pin him to the wall, you try to suck his blood and maybe turn him into a vampire like you but he keeps squirming

"Let me go, you stupid blood eating demon!" He shouts as he flails around, what do you do to get his blood?
