I would tie off his arm,

watch it slowly turning first red,

blue, and then black,

loosening the string I would use

several times during the procedure to prolong it.

It would take a while, but I've got time,

they aren't going anywhere,

nor will they ever again.

While the string takes care of his arm,

I would cut off parts off his skin, his flesh.

It's girlfriend would be watching,

watching as I carefully take care of it's body,

cutting apart every inch that isn't life-threatening for now.

The male would lie on a plastic sheet to collect it's blood

and other bodily fluids.

They will be of use later.

While cutting him open,

I would gather as much blood as I can

in a perfectly ordinary glass,

bring it to it's girlfriends mouth, feed her.

I don't want the blood to be too diluted,

hence why I wouldn't use the fluids from the sheet.
