She wants him to eat her[and you]? You have heard of girls doing their all for a boy, but being swallowed alive and digested sounds extreme to you. But now that you think back, you realize Pam has been perfectly accepting of this idea for a long time. You were the one who focused on his hot body and ignored what she was doing and thinking.
Well, never mind that now. Is there a way out?
...wait...do you actually need one?...

From somewhere... Pam's brain?, something the nurse said?, some piece of conversation somewhere?, you recall that the vile stuff you drank in the nurse's office meant that if you are digested, you reform there. ...That...well, maybe it's not ok, but it sure seems better than the alternative. Anyway you stop panicing.
Or maybe you start. Pam's invitation to dine on her has been accepted and his mouth is opening wide and approaches her head, as she just lies there smiling. [Now how can you see that? Well, given you are not sure how you can see at all, maybe you shouldn't worry about the details. Particularly when you are about to be devoured alive... But you don't seem able to do much about that...]
Pam's head vanishes into his mouth, and he starts swallowing her slender neck. Then his mouth wides to take in Pam's shoulders. Which means you are next. It's been fun having his chest rub against you as he was eating Pam, but now he has to straighten out and the only part of him close to you is his lips.
Which are pretty nice... They caress you as they move over you, and then his tongue gets to work, licking all over you in a surprisingly stimulating manner. Your burgeoning apices are getting aroused. You feel yourself swell, and move against him. As he tastes one nipple, both of your's throbe, and become taut. You, and Pam, are aching with need, and then explode massively.
You are a little disappointed when he resumes eating and you are squeezed as you are forced into his throat. However, once in there, you find your slide down to the stomach is quite erotic. Each inch stimulates you and there seems to be an infinite number of inches. You can take only so much and join Pam in a blinding release that leaves both of you pretty much out of it.
You wake in his belly and find Pam not only awake, but active, caressing you, and herself, to another climax. She tries for yet another, but this has all taken a lot out of her and she drifts off, as do you a few moments later.

You wake in a very different location, presumably the nurse's office, or a part of it. In any case, there is no sign of your man around. You are still part of Pam, two of her more important parts in fact. She is just starting to wake as you are looking over the room, which contains several other students on cots, presumably also recovering from being digested. However, you don't get much chance to look. As soon as she can stand, Pam mutters "I've got to get back to my room. He may call at any time." and bolts for the door.
