Sonja finds Larry reading to her as she is digested quite nice. Of course it doesn't hurt that she selected a comic with a good deal of text and not much in the way of dramatic pictures. However Larry does a good job of reading in any case.
And really, it is nice and comfortable in his belly. Oh, it could be better, but her main complaint is that it is on the dull side. There just isn't much she can do in here.
Hmm...is that why so many of Jason's meals had played with themselves? That it was just something to do? That would make sense, and she had not felt any...well, not that much urge to finger herself. It would fit if she is just distracted from the desire.

"Sorry Sonja. Ma says I have to do some chores. I'll finish the comic in an hour or so."

"No problem" Well, it is, but it's the normal daily problem for a girl. It's not one she can expect much sympathy about even if she did complain. Besides, she may get some evidence on her theory...

At first it seems she will be refuting her own idea. Nothing unusually sexy about her thoughts. Just the normal stuff, which of course does have the random sexual thought..
It is something of a shock to realize the relatively rare sexual thought had become the most common kind. And they are not going away. They can be banished, but they creep back in and spread... It's not long before they are in the majority again...
Part of the problem seems to be that Larry is moving around. While Sonja is well insulated in his stomach, some of his movement seems to leak thru, and produces a gently caressing movement on her skin, a movement that is definitely pleasant, and definitely erotic.
The idea of seeking relief while Larry is "watching" is scary, and Sonja tries to keep herself under control. But her desires keep getting worse and eventually her hand slips between her legs, seeking her desperate need.
Between fear of Larry finding out what he is very likely to find out and simple inexperience [Jason had been Sonja only a minority of the time despite Anne liking to change him and most of that time had been too busy to even consider the idea.], Sonja makes little progress at first. She adds her other hand to caress her eager breasts, but without much effect.
But eventually, somehow she starts to do something right. She can feel her excitement rise. Her breasts become heated and her nipples hard. Her womanly center is ready... She is almost there...
Then she is there. She explodes into a thousand pieces in a real massive orgasm. Then she is trying to shrink into a tiny ball. Had she really been screaming like a banshee? and flailing all limbs in all directions? Had Larry heard? or felt it? She didn't see how he couldn't have...
However, whether from ignorance or politeness, Larry gives no sign and Sonja can relax, and notice that one thing her self indulgence had done is speed up her rate of digestion. She is already soft, and rapidly starting to lose her shape. It is not long before she is once again just a puddle, which is soon converted into Larry's nutrition.

Once again, Sonja finds herself naked in Larry's bedroom. At least this time he is absent, and her clothing is easily found. But once she is dressed, she starts to think.
This is happening way too often. She just shouldn't be appearing here again and again. What is causing this?
It takes a little while, but she comes up with an idea. Her clothes are here. And girls reform near their clothing. Most girls have lots of clothing, and so relatively rarely reform near what they had been wearing before, but Sonja effectively only had this set of garments. When Anne made Jason Sonja, she just changed his clothing into her clothing. She didn't have any actual Sonja clothing, other than these. [Well, there are a few sexy things she had worn to produce some hot pictures for Jason, but she had barely worn them long enough to take the pictures. It would seem they don't count.] So if she always reforms near clothing of hers, she has to reform here. And she dare not tell Larry this, she may be trapped here "forever", just being eaten time after time.
She is not sure if she is more worried about that, or by the fact she is not really distressed by that.
