Eventually Kuu quiets down, allowing you to nurse in peace.

For a little while. Then she says "OK, that should be enough for now...".

But the milk tastes so good. So you ignore her and continue to nurse for a few more minutes. "Dear, that's enough."

That may be her opinion, but... "Gia! Stop! Right now!" Of course you don't.

"OK, in that case..." You feel her, in some way, struggling to stop the flow of milk, but it continues to flow.

"Gia..Please! You're swallowing all of me!"

What do you know? You are. Kuu's arms and legs are gone, apparently converted into all that milk you have been drinking, or it is stored in her boobs, which are twice their former size, full of delicious milk. Which you are going to drink.

But not only that. Kuu is helpless under you. Why not have a little fun with her first? One hand starts to caress her damp heat, while the other squeezes the breast you are not drinking from. Kuu protests "Gia! Stop nursing, please!", but she can't resist the stimulation. Her yells become gasps and quicker and quicker until she explodes into a thousand pieces, leaving her in a faint.
Excellent. You can continue to nurse without her badgering. Mothers! They just think they know everything and don't want to let you do the fun stuff.

By the time Kuu wakes, there is little left of her besides a couple of huge breasts. She still has a mouth, briefly, and uses it "We are going to have a talk about this."
Bah, what can she do as a tummy full of milk? And that is what you are rapidly converting the rest of her into. Soon she is just a pair of breasts, then just one, and then just a pleasant taste in your mouth, and a fullness in your belly.

My, and it is just bedtime too. You did spend quite some time in Kuu's womb. Well, off to bed while you digest this great meal.

It is no great problem finding your way back to your room, where you find your roommate already sleeping. Her massive belly tells you that she too is not going to be sleeping alone tonight. So into your bed and sleep.

For a little while. Then you are woken by a pounding on the door and an angry female voice demanding entry. Still half asleep, you grope your way there and open the door before you manage to realize that the voice is Kuu's, and that your belly is once again flat.
You realize this is not good for you about the time you see Kuu's mouth suddenly fill your vision. A second later, you are on the way to her stomach.

You are fully awake by the time you are fully into it, but it's a little late to do anything. Instead you get to listen to Kuu saying "You have earned yourself a time out, young lady. Now let's see... What is a proper punishment?
