Negotiate

What choice did I have? I quickly weighed my tactical options, but the demon was far too powerful for me to handle alone. With that moronic warlock knocked out, my chances were slim against a six-foot-seven fel entity with biceps larger than my head. Submitting to the inevitable wasn’t giving up, I told myself, it was simply a... high-level tactical self-preservation.

“F-fine...” I grumbled, trying to sound like a stoic general making a painful treaty. “As long as you’re gentle... and respectful, I’ll permit this!”
“Gentle and respectful? Permit this? As if you have any choice, dear paladin,” the demon laughed. “But I can promise you’ll find it highly educational.”
“Bah! Educational! We humans don’t learn from creatures like you! We are better, purer...”
“Oh, but you’re not. You’re really, really not,” she purred, motioning toward the unconscious spellcaster lying face-down in the dirt nearby. “Do you think you’re the first human I’ve met? Almost every day, some amateur warlock summons me trying to be the boss, but usually ends up with me bossing them! Hey, most of them enjoy it... and so will you!”

She took a slow step back, casually flaunting her overwhelming physical advantage. Her broad, voluptuous chest swayed gently above an equally formidable male member, leaving me swallowing hard. A treacherous arousal was running through my body despite me trying to suppress it... Was this the demon’s making? Surely it was!

“Now, let’s stop wasting precious time,” she smirked, “and see just how durable you really are!”

She hooked her claws into the waistband of my thin breeches, yanking them down past my hips until they pooled uselessly around my ankles. My shamefully erect shaft sprang free in the dim cellar light, completely ruining any remaining shred of my professional dignity.

She let out a low chuckle at my body’s utter lack of discipline, then reached down to guide her own massive cock. Lifting me effortlessly by the thighs, she pinned me up against the sturdy oak barrel. I gasped, my legs wrapping around her waist out of sheer survival instinct as her heavy breasts crushed against my chest. She aligned her slick tip at my entrance, teasing the rim for an agonizing second before driving herself smoothly inside.

I threw my head back, a loud, embarrassing moan escaping my throat as her massive size stretched me to my absolute limit. She filled me completely, her broad head hitting every sensitive nerve inside me all at once.

“W... Wait! S-slow down! You’ll... rip me apart!” I squeaked, but she didn’t care.

She set a slow, agonizingly deep rhythm, sliding out until only her tip remained before burying herself all the way back to the hilt. The friction was searing, slick, and outrageously potent. Every heavy thrust sent shocks of intense sensation straight up my spine, making my toes curl and my hips involuntarily buck forward to meet her pace... purely a muscle spasm, I assured myself.

Down below, her heavy scrotum slapped steadily against my rear with every plunge, a wet, carnal beat echoing off the stone walls alongside my decidedly un-paladin-like whimpers. My shaft rubbed helplessly against her flat stomach with every surge, leaking pre-cum over her skin as she picked up speed, turning her deep strokes into a relentless, pounding rhythm that left my dignity in complete ruins.

It felt like hours before she was finally done with me. By the time she finished, my physical stamina was completely drained, her heavy load was settled deep inside me, and my mental capacity had been reduced to a blank slate.

Before opening a crackling portal back to the void, she leaned down and seared a tiny, glowing demonic sigil into the skin just above my right buttock.

Great, I thought numbly as I collapsed against the barrel, staring at the ceiling. A permanent mark...!
