He picks the Fox-girl.

"Her. I want her."

The girl woke up with a start.
Her head whips around as she takes in her surroundings. A dungeon. A cold dark room with stone walls.
She is hanging by her wrists from the ceiling. You are very familiar with this sensation.
She struggles, her bonds rattling in response. She spouts a few curse-words right back.

"Oh, you're a feisty one, aren't you?" You say.
Her head darts around the room at the sound of your voice. It's dark enough that she cannot see you from where you are.
"Huh!? Who's there? Where am I?"
"I like the feisty ones..."
You step out of the corner where you had been lurking. She almost seems relieved to see another mortal.
"Oh, thank the Nine... Hey, lassie, can you get me out of these? Yer stuck here too, yeah? Ya look it. We can get out together."
Her accent is thick. It's the kind of brogue you can only get from a lifetime in the Highlands.
"Oh, Neir, that voice of hers is so lovely... Your going to sound fantastic with that music coming out of your mouth..." You say.
"The hells are you talking about? Who are you talking...?" She trails off as Neir steps into the light.
"What in the world are you?"
You step aside for him. He gets up close to her, cupping her cheek with his palm.
"I am a demon, girl. Have they told tales of my kind in your land?"
"No. No, they have not. Not anymore. We shant let cave-dwelling knobs like yourselves into our neck of the woods." She's putting on a brave face, but she is plainly terrified. Her eyes keep darting down to look at Neir's cock. "But, I've travelled far enough to hear of you lot."
"And what have you heard?"
"Nothing good. You eat the hearts of men. Not my kinda crowd."
"Not exactly untrue, I must admit..."
"Is that what ya going to do to me? Eat my heart?"
"In a sense."

You're seated on a stool nearby. You pick at your nails as Neir does his thing. You were going to let him do this on his own, but you just can't help yourself.
"You keep looking at it." You pipe up.
They both stop talking.
"At what?" says the girl.
"His cock." You say back.
"What?!" She says, scandalized.
Her face goes red.
"Oh, look, she's blushing!" You say as you step up.
"Damn you, girl!"
You run a finger up and down his shaft. "You know, if you wanted to try it, all you had to do is ask. It is why we're here, after all..."
Her eyes go wide. "What?"
You wrap your hand around his cock, giving it a few pumps. It perks up a little, growing harder.
"Oh, didn't I tell you? He is here to fuck you."

She can only stammer as you wrap your arms around her neck in a loving embrace. You stare deeply into her eyes. With an idle hand you stroke her pointy ears. They are so soft.
"We need your body, girl. But we can't use it while your soul is still in it. And we can't take your soul out of you until we break your soul in half. Hence, this."
You wiggle your ass in Neir's direction and he seems to get the message. He puts on hand on your behind and the other on his cock, stroking himself to attention.
"He is going to fuck the soul out of your body. It will be glorious."
"But before he does that he's going to- mnh -fuck me." Your words catch in your throat for a second as Neir slips his cock into you.
He starts slowly, pushing into you and sliding back out. You nuzzle the girls neck. She tries to pull away but there isn't much she can do.
"What is your- nhn -name, girl?" You ask.
"My what?" She says.
"Your name. I can't keep calling you girl, can I?"
"I'm... Uh... My name is Perin."
"My, that's a lovely name!"
You glance back at Neir.
"Are you going- ah -to use it, dear?"
"Ngh- No, I think I will keep my own. I'm rather- ghn -attached to it."
"Oh, that's good. It's a nice name." You look back at Perin. "See, I am stuck using this- ah -girls name. She has a family waiting for her. Do you have any- mgh -family?"
"No. Not a one. All gone."
"Ah, gods, that's a- ah -shame."

Neir picks up his pace. A grin spreads across your face as Perin's eyes go even wider. You pull her in close and kiss her. With your hand on the back of her head, she has **** but to lock lips with you. A muffled sound attempts an escape from her mouth, but has nowhere to go.
Neir grunts as his balls tighten. A burst of something hot and wet explodes in the pit of your stomach. You let out a loud moan right in the girls ear.
Your knees feel weak as your head falls into the crook of her shoulder.
"Gods, that felt good..."
"Are you ready for your turn, girl?"
