Whore for her.

“You see, Heather,” Winny whispers intimately in your ear. “Being head of the breeding program is fun, but it doesn’t pay well. And I have expensive tastes. So, I thought I’d arrange some… pocket money.”

She pushes you roughly to your hands and knees. “You can come in now,” she adds more loudly, and you hear a door open behind you.

“You see, ****,” she continues to you “**** you breeder bitches is a perk for those who work here. But I saw a business opportunity. So, I intend to pimp your slutty arse out to anyone who’ll pay to fuck it. Your mouth and tits too. Not your cunt, though. That’s just for monsters. We wouldn’t want you knocked up with a human baby, now would we? Of course, once you’re fat with your first litter, things will be different So, are you going to be a good little whore for me?”

“Yes, mistress…” you moan.

“Do it,” she says to whoever is standing behind you. A cock is immediately thrust roughly into your arsehole.

You can’t see who’s doing it, and you don’t care. All that matters is you’re being fucked. You moan and pant like a bitch in heat – which you of course are, and have been for months. You feel the same joyous submission you felt when your mate mounted you. Your mouth gapes, and your eyes roll back with pleasure.

Winny watches you with a mixture of amusement, disgust and arousal.

“Does it feel good, whore?” she asks.

“Yes, mistress!” you cry.

“Show me!”

She opens her lab coat, revealing she wears only lingerie underneath – a corset and brief panties. She slides these down her legs, leaving her naked below the waist. Then, standing with her legs slightly apart, Then she pushes her cunt against your face, twisting her hands in your hair to keep you there. You eagerly start to lick her.

The humiliation, combined with the sensation of the cock pounding your bum, is enough to drive you over the edge into climax. “Cumming while being whored and arse ****,” Winny murmurs. “Pathetic.”

The unseen man behind you shoots his seed into your bowels, but the experience is far from over – another simple takes his place. Four in all have their way with your butthole, and you lose count of how many times you cum. Winny keeps you servicing her the entire time, occasionally climaxing herself.

When the experience is over and the men have left, Winny wipes their seed from your arse-crack with a damp cloth. The gesture is almost gentle and loving, but her skilled fingers stroke against your tender, abused arsehole in a way that arouses you again.

She breaks your reverie with a sharp slap to your arse. “Time to get up, slut. There are monsters waiting for you.” That prospect is enough to make you move more eagerly.

This time, Winny doesn’t bother to let you cover your nakedness, parading you through the corridors in only your bare skin. She takes you to a white-tiled pit, sterile and austere, and leaves you there. Above, one-way windows look down on you. You sin on the floor, gently frigging yourself as you wait.
