Negotiate

What choice did I have? I quickly weighed my tactical options, but the demon was far too powerful for my current power level. Heck, I couldn’t even parry an angry tavern brawler, let alone a six-foot-seven fel entity with biceps larger than my head. Submitting to the inevitable wasn’t giving up, but it was rather 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 breach of protocol!”
“Gentle and respectful? That’s simply not in my skillset, paladin,” the demon laughed. “But I can promise you’ll find it highly educational.”
“I won’t! We humans are refined, disciplined creatures... well, I am at the very least!”
“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? Hardly a week goes by without some amateur warlock summons me trying to be the boss... and fails, inevitably. Luckily for them, I never fail to give them a fun time!”

She took a slow step back as her hand slid down her erect cock and swung it around, causing my eyes to drift down. My body was betraying every single principle of my holy order, but let’s be honest, running was no longer on the table.

“Now, let’s stop wasting precious time,” she smirked, “and see just how durable this little paladin really is.”

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! This is terrible form!” I squeaked, but she didn’t care about combat standards.

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... it was 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, already leaking pre-cum! Soon, 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 which time 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. I’m definitely going to need a very convincing excuse for the High Prelate.
