When the blood fills his mouth, it's kind of the most incredible feeling. Like walking through the desert for hours and finally taking a drink of water. It's hard not to get lost in it, really. This is what this new body of his needs, what he hasn't been able to get enough of since the first time he really lost control.

And it hasn't even been that long since then.

He feels like he could feed forever, doing nothing but drink blood until... oh, who cares when he'd stop. When there isn't any left, he supposes.

It's when an arm wraps around his shoulder that he can really shake himself out of it, and he pulls his teeth away from Mettaton's neck, looking satisfied, but also a little concerned.

"You alright?"
