Better check it out

Carl might be a depraved man and might totally deserve what’s coming to him, but your duty as a paladin to the Burning Rose demands you at least check it out.
You exit the room, armed with the holy sword and dressed in only your underclothes. As you sneak down the stairs you can hear Carl and Xallia fornicating. In their haste to fulfilling their sexual satisfaction, they have left the door to the kitchen half open. Silently, you get up to the door, and take a look inside.

You are not surprised to see them both naked. Xallia is seated on the kitchen table and Carl stand in front of her. He laughs as he plays with Xallia’s breasts and occasionally strokes his erect dick.
Xallia places her hand on the back of Carl’s head and pulls him to her chest. Carl quickly latches on to her nipples and begins sucking on it.
As you hear Carl moan, you absentmindedly caress a hand over your own breasts and vaguely notice your nipples have hardened.

“Do you like it?” Xallia asks her lover.
Carl pulls back and says “I’m normally not one for mothers milk. But yours seems to be something special.”
Xallia grins and cups her own breasts. She squeezes them a little, causing a few drops of milk to appear on her nipples.
“You can have as much as you like, my dear.”
Carl traces his tongue across Xallia’s nipples and licks up her milk. Then he puts his mouth on her nipple again and starts to suck more milk from her breast, while stroking his very manly cock.
As Carl drinks from Xallia, the daemoness wraps her arms around him and holds him like a mother holds her child. It is really quite serene and beautiful. Maybe you have misjudged Xallia.

Just as you are about to stop spying and return to your room, you notice something peculiar. Carl’s hair seemed … longer. You stare at it a bit more and yes, you’re right. Carl’s hair is growing. Could it be because of the succubus milk?
But then you see something that shocks you to your core. Carl’s dick … it’s shorter. At the start of the act, he was masturbating with long proud strokes. But now those strokes are shorter and he still caresses his full length.
You hear Xallia moan and say “You’re doing good, sweetie. Drink as much as you want.”
As Carl releases Xallia’s left breast you see his much less hairy chest and notice two small bumps which shouldn’t belong on a man. As he drinks the milk from Xallia’s right breast, these bumps grow bigger and develop into breasts.
The hair on his head grows beyond his shoulders and the hair on his chest shrinks away completely. His facial features shift to a more feminine face. His moans become higher and start to sound feminine. His hips broaden and his testicles get absorbed into his body.
Soon there is nothing left of him but a middle aged woman with a tiny dick.

Even though his dick is too small to wrap his hand on, he is still trying to masturbate. He simply rubs his fingers on the pathetic excuse of a penis, like you would rub your clitoris. Soon, a slit appears between Carl’s legs, the tiny penis takes on the shape of a clitoris, and takes is proper place between his lower lips.
That is when Xallia pulls Carl away from her breasts and says. “Very well done Carly. You are a wonderful girl. As a reward, I’ll help you become a woman.”

This is bad. Not only has Xallia changed Carl into a girl, but now she is planning to **** her. As a paladin, you should go in and rescue Carly, but this unholy transformation you just beheld makes you unable to think clearly.
