I mean, if we are going with that, than you're still gonna run into, at some point, the problem of maintaining uh... well, adequate bloodflow/pressure to the disco stick.

So... sure, sure, you can keep going, assuming you can handle them augmenting their blood flow with your own.

At that point this begins to remind me of the mouse with the electrode hooked up to the pleasure center of its brain, just keeps pushing the button until it starves to death.

Sooo... should you just fully donate your own entire blood supply....well, what are vampire rules on the consentability of corpses?

Can they enter a room or home with no specific owner?

... I think they can.
