With Dolly squashed up against you and the two of you crammed into Ashley's stomach with several other girls, it sounds like a lot of work to wiggle around enough to swallow her. Not that it would not be worth it, not by a long shot, but Dolly has suggested an alternative that will be a lot of fun too, and which can be done with the lass right next to you...
A quick kiss and you start getting yourself in position, a process not made quicker by the dark and your other stomach mates complaining about you bumping into them. But eventually your staff is in position to play key to her lock, and Dolly is saying "Yes, thAT'S THE place!" as you plunge your member into the damp petals of her womanhood and resume the age old rhythm.
Dolly's cries are matched by those of the other women, tho hardly for the same reason. Some just grumble about your bumping into them with your strokes. Others are demanding you get a room, but there are voices of encouragement and calling Dolly lucky to get a little fun.
You are the one having most of the fun. Dolly is sticking to her idea of doing everything her superiors want in the hope they will free her as a reward. Just why Dolly thinks you have any say is hard to say. As a male, you are real low on the totem pole. Of course Dolly is the low of the low, so you do rank her. But as far as you can tell, she wouldn't be risking much to flip you the bird.
However Dolly doesn't seem to want to risk it. Instead, she is doing her best to give you a great ride, with a great deal of success. Quickly you shoot off, but both of you resume your efforts. Dolly's own excitement is increasing too, but she continues to focus on your pleasure, with a great amount of success. You have one of the best climaxes you can recall even as Dolly surrenders to her own pleasure.
You relax for a moment and realize the comments of the other lasses have largely ceased. They have nearly all fallen asleep. Indeed, you realize you are not far from doing the same. No surprise. You just can't stay awake in somebody's belly. However, Dolly is not willing to quit yet and continues to rock on your rod, quite pleasantly for you. You aren't sure, but you may make it twice more before you are completely gone.

You wake in what looks like the nurse's office, but is different enough to notice. Like the nurse's office, you see several cots for reforming, and several of the girls you cock vored are waking and getting off them.
Somehow Dolly has managed to reform on top of you, and your piece inside her womanly center. However when your strengthening staff wakes her, she hops off. "Sorry, we slaves have got to get back to work. I'll have to find time for you later."

Before she can leave, you ask "Wait. Where are we?"

"In the basement. That's where we slaves normally reform. We do reform elsewhere at times, but this is the normal spot. One big reason we don't try to escape or anything. Sooner or later, we get eaten, and end up right back here, with whatever punishment still waiting for us. There's just no escape."
With that she vanishes, and you find yourself at loose ends for the moment. Ashley has taken Candy to the initiation ceremony and will be busy for some time. You can either attend the ceremony too, or take this chance to explore the campus some more.
