"....AH!"
The whip striking you across your naked torso awoke you in your usual spot, spread out on a horizontal wooden X with your limbs tied to one of its ends. At least there was a headrest.
The lights in the prison dungeon turned on and your usual torturer greeted you, sugary-sweet as always.
"Good morning~"

But today she had more to say before getting back to her favorite hobby.
The gray-haired girl caressed your cheek with her left while her right scratched across the mark her whip had left on you.
"Great news, soldier! The war for the Southern Islands is over. What remains of your comrades here, and your allies on The Peninsula, has been merged with your main force in the homeland. There's going to be amnesties!"

You could only respond with a grim laugh.
"Amnesty? Not after what I did with that Pavolia chick. Even though I didn't force myself on her."

Agent V7 responded with five lashes to your chest (that you endured silently) and one lash to your crotch (that got the kind of high-pitched yelp she loved out of you).
"Smart women offer themselves before enemy forces use force to force the issue, soldier. You know that."

The girl climbed on top of you, her modest chest on your belly and thick thighs around your neck. The big innovation of today was her not wearing anything at all, looking even better naked than you had imagined she would, and revealing that her hair was gray and long everywhere. You could feel her heat, her quick heartbeat, her nipples hardening against your muscles.

"But you're right, the family advertised a reward for your death and..."warned" against letting you go free."

You had dreaded that outcome after being captured, but now it felt almost relieving to have it confirmed - the last doubts removed. What felt the opposite of relieving was Zeta choking you with her sweaty thighs; though holding your breath was wise anyway, considering how close her stinky pubic jungle had gotten to your nose.

"You have no value as a prisoner now, and I could use that family's reward! Luckily for you, I've grown quite fond of you~"
The beauty began running her hands across your muscular hips and thighs, playing with your dick and balls whenever her hands came across her beloved toys.
"And I could use a victim without value...I'll kill one of the less fun prisoners and pretend he was you to get the reward, before taking you home. Right after our morning routine tomorrow!"

The agent's soft voice and skin, plus her delicate fingers being 100% focused on jerking you off and fondling your balls now, got you diamond-hard despite your body's increasing panic over lacking oxygen. How hard the meaty, muscular legs of your potential savior squeezed your skull was only a tertiary concern at this point.

"I know being a victim isn't great, but it sure beats being a soldier on the losing side. Do you disagree?"

The agent spoke as deliberately as she moved, and your survival instinct began to overrule your pride.
"Ugh...a...air...pl-...please! Air...a-AHH! FUUUCK!"

Only once Zeta's fist clenched around your left testicle did you manage to force a good amount of air past her thighs' stranglehold. Though your scream probably wouldn't have been as strong without the awful pain of Zeta digging her manicured nails into your glans.

"Ugh, this is so half-assed - you can talk, but not really. You know what? Since I can't afford you ratting me out, I might just cut out your tongue. Or claw and bite it out, like this..."
Increasingly animalistic noises escaped your throat as Zeta clawed at your foreskin, followed by heavy breathing as she slid further down your body, releasing your neck just in time. Once the basic need for oxygen was met and Zeta's teeth were starting to dig into your cock you finally managed to speak with intent, forgoing all claim to pride and defiance.

"Mercy, Agent! Mercy, Miss Zeta, I beg you!!!"

Her hands and mouth left your crotch alone as she spun herself around on you acrobatically, her gray eyes meeting yours as she smiled.
"Mercy for what...your poor precious thing, or your tongue?"

All you had left was pleading.
"...both, maybe?"

The most endearing torturer in a century laughed her soft, refined laugh.
"Well, I'm quite fond of CBT...and I can't exactly have that without your C and B. But your tongue, your potential traitor tongue...you should prove what it can do for me, hm~?"

Zeta sat up and planted her cheeks on your face, supple enough to make breathing harder again.
"Time to eat out a hot&humid elite agent, soldier! First the back, then the front. Hope you don't mind the undergrowth~"

Your favourite Guns N' Roses song came to mind as you obliged. Anything better than being executed for some light war crimes, right?
It was human nature to downplay the severity of the inevitable, of course...but deep down, the most rotten part of your brain told you that being a long-time victim of this agent might be kind of hot.
