Oh, that's cool. I'm not normal either. I'm actually the.. err, Antichrist. Which means I have a lot of great power in me, and abilities, one of which is self-healing and restored energy. So you can feed all you like.
I also have a lot of stamina too.. and I'm sure you know what that means in bed, hmm? ;)
And I'd like to do this without being hurt. We can also do this more than once. Also... I am also really good with my mouth too. Which I'd be happy to prove to you. After the sex of course, since you really need feeding now. I'm Damien.
