Perin is taken by Neir.

You can feel Neir's spunk sliding down your thighs as he pulls out of your pussy.

Perin has started to breathe heavily. She struggles in her bonds, to no avail.
"What in the pit is wrong with ya, ya fucking whore?!"
You squat down, letting Neir's jizz ooze out of you onto the floor. You take great pleasure in catching some on your finger and tasting it.
"I would not speak to my mistress that way." Neir says in your defense.
"No, No, Neir, let her speak."
Perin has tears in her eyes. You thought she would last longer than this.
"Why would ya let a damn hellspawn stick 'imself in ya, let alone let 'im plant his seed in ya?!"
You stand up. For a moment, you stare her in the eyes. Then, your hand shoots up and grabs hold of her neck! Her eyes bulge and she gasps for air.
"I think that you do not understand the nature of my being, you little cunt!"
Her feet kick out, looking for a way to stop this and not finding it.
"I am not some mortal wench, taken in the night to swell the ranks of the demonic horde! I am a righteous warrior, granted glorious purpose by the great Lady Malbogia to take the surface world and bring the kin of Ifrit into a bountiful new era!"
"This man has been by my side in countless battles! If I want him to stain my insides, I will have it! And I will have him stain yours!"

"Don't you fuckin' dare!" She screams.
"Is she ready?" Neir says.
"She will be..." You say.
You squat again, coming face to face with Perin's pussy. You take hold of one of her ankles and hold it over your shoulder. With her virtue on full display, you lean in and give it a nice long lick. As you run your tongue up the length of her pussy, she lets out a long keening wail.
"AAAAHHHHHNNNGG!!!"
You flick her clit with the tip of your tongue. Her other leg swings wildly. She attempts to aim it at your head, but you catch it without even looking. You keep probing her hole.
"Bloody fooking bastards!!!" She cries out.
She starts to let out a series of short sudden breaths. In the midst of your ministrations, your eyes dart up to meet hers, almost daring her to hold it in.
But alas, she cannot. The dam bursts. Her face scrunches up, her back arches and her pussy squirts a sweet something right down your throat.
"AH!"
A single cry is all you get. But it's all you need.
"Take her!"

Neir steps up to the bound woman. He rolls his head and grabs her ankles, lifting them up and spreading her legs wide. Still recovering from the orgasm you gave her, Perin tries to say something, anything, that would make him stop, but nothing is going to stop this.
"No, no, no- NGH!!!"
He hilts himself inside her in one thrust. Still on the floor, you crawl underneath her and get a good look. He is buried deep in her.
"Damn, girl, you are impressive!" You say.
You spring up to face her. Her eyes are wide with shock.
"This body wasn't so lucky." You say, tweaking one of your nipples. "She was a virgin, can you believe that?!"
You shove three fingers into your own pussy, getting off on the sight of Neir thrusting up into the Fox-girl.
"It took hours before I could fit all of him inside of me! But it was worth it, don't you agree?!"
The rhythmic sounds of Neirs' balls slapping against her flesh fills the room. They are accompanied by Perins' moaning.
SLAP SLAP SLAP
AH AH AH
"I am going to miss his cock, I will admit. But it will be all worth it when I'm sitting on that throne. And with your pretty little face right between my legs!"
SLAP SLAP SLAP
AH AH AH
Neir is drenched in sweat. You grab his face and kiss him deeply.
As he keeps fucking this whore and you fuck yourself, the room is a cacophony of moans.

Neir speeds up.
"Mistress, I'm going to-"
"CUM INSIDE! DRENCH HER INSIDES!" You scream, bringing yourself over the edge.
You, Neir and Perin all cum at once. Your knees give out as you crest the wave between your legs, giving you a great view of Perin's cunt being flooded with cum. Neirs' cock pulses once, twice, three times before he pulls out, gobs of jizz falling to the floor. You crawl over and start licking it out.

Perfect.
