"Oh, why not?" Not that you are really interested, but you don't want your food getting nervous and maybe running away. So pretending a little sympathy is a good idea.

"I've never vored anyone ... not really anyway..."

"Not really?"

"Not so it really counts..."

"And how would that be?"

"Well, ... my boyfriend made all sorts of promises and said he really loved me, and, ... well, ... things happened."

"You were upset by that?"

"Well, not really... In fact I was rather happy... until I walked in on him and my best friend the next day!
"I was so furious! I couldn't think straight. I just wanted to punish those traitors... And the next thing I knew, I had swallowed both their heads...
"Once I had started, I just could not stop. Not when that bastard kept on screwing that slut. He kept on doing her even as I was swallowing both of them and he didn't stop even when they were in my belly, the !@#$."

You have to say you admire the lad for sticking to the job under adverse conditions. Not that it is wise to tell Candy that.

"People of course noticed my big belly and started accusing me of being a vore. But I can't be. I didn't eat some innocent. They deserved their fate. Any girl would have done the same..."

"Well, any girl that could have... And that was a quite impressive feat for the first time too. But we vore are defined by being able to eat people, not by who we eat. So yes, you do belong here.
"And you should enjoy being here if you don't want to eat innocent people. That potion you just took means that anyone you eat will reform as good as new, right here in the nurse's office. So you won't be harming anyone while you are here."

"But..."

"No, Candy. You are a vore and need to get used to that. You will find it wonderful here once you do." Spoken with your hours of greater experience, and ignoring nearly getting digested.
"Now if you will get on the examining table... Good. Now put your legs in the stirrups... Good..."

Very good from your view. She may not be completely helpless, but she is close enough for your purposes. The question merely is whether to vore her or screw her too while you are at it. That would be more fun, but it could have drawbacks. Did that release you signed cover rape? It seemed to cover everything, and so it should, but you can't say for sure. Of course the nurse didn't seem upset at your using her, so it is likely ok. But the nurse is another point. She is well digested and will be reforming soon. You have enough time to vore this lass, but to sex her and vore her? That will be cutting it close. You don't want to be about halfway done swallowing Candy when the nurse comes back into the room. But you might make it, and it will be great fun...
