Vampire Seduction

You're at a Halloween party when I catch your eye from across the room. We're both dressed as vampires. You come up to me to chat, noticing the red cup in my hand. Do you want to try some? I bring you to a bedroom - a quiet, private place where we can be alone. You have a sip of the red liquid and realize that I'm either very committed to my costume ... or I'm totally insane! Or, I point out ... I'm a real vampire. I reveal my long vampire fangs and you scream in terror! Calm down, I'm not going to hurt you. Actually, I'm looking for someone to spend eternity with. Since you're uncertain about being turned into a real vampire, let me show you what you could look forward to ... things we could do every night for centuries to come. You give in to the temptation and we start having sex. I won't let you cum unless you agree to spend eternity with me ... but is it really that simple?
