"OK, you are two people now. I'm not really sure for how long. You won't merge if you touch or anything, but I've never done this before and I don't know what happens long term. Maybe you will grow into two completely different people. Maybe you will have to rejoin after awhile. I haven't tried to stay apart for long since things went kinda bad that first time. So be careful. Let me know how you are getting on."

Neither Jason nor Sonja seem greatly worried about this. They are too excited to find the disturbing thoughts gone. Jason is again all boy and Sonja is all girl.
And girls are food... "Say Sonja..." It is a bit odd asking yourself to be your snack, even if you have been staring at your poster for a long time.

Sonja also finds this a bit off setting, but..."Can we wait until after I do a little shopping? It is rather annoying to always reform at the same place."

"I could just give you a set of what is in Jason's closet..." Anne offers.

"Now where is the fun in that?" Sonja asks. It is a question Anne has to admit she has no answer for. Shopping is fun, and with no male aspect, Sonja likely thinks it even more so.

"OK, let's go." And two happy lasses lead a less thrilled lad out for a round of shopping for women's clothing.
Who finds it a lot more pleasant than he had thought.
The reason is that there is no pretense between Sonja and Jason. Their thoughts, if no longer one, are still known to each other. Jason may no longer understand what Sonja had been thinking, but he still remembers her thoughts, and she recalls his.
In particular, she recalls his love of looking at underclad lasses, herself in particular. And even if there is a limit, Sonja can still feel a pleasure in exhibiting herself.
Her first outfit is merely a bit improper. And she can see Jason's interest in shopping increase as she models it. Her 2nd really shouldn't be worn to school, and her 3rd choice definitely is not for school wear.
That is when she starts asking his opinion of her underwear...
Yes, Jason is really enjoying the shopping now, and Sonja finds she is enjoying it too. Of course she is also enjoying the shopping itself and between times giving Jason a peak, she manages to buy several outfits of a more practical nature. But having Jason just stand there bug-eyed as she struts is quite a charge.

The natural result of all this is a raging appetite for Jason. Whether that is good or bad, Sonja is not quite sure. The general idea sounds great. Still, except for Larry, she hasn't been eaten before. Even if she know she will enjoy it, she feels she has a right to feel nervous about the first time.

Which is coming quickly. Even as she finishes her shopping, Jason is asking "Head first? or feet first?"
