The Empress lay tangled in her dark red, wispy tunic, the thin fabric clinging to her sweat-slicked skin, barely concealing her form. She shifted under the sheets, her breaths uneven, moans soft but growing more desperate as the dream overtook her.

Heat… strong hands…

She saw the Barbarian King—her enemy, the thorn in the side of her Empire—towering over her, his eyes dark with lust.

Can't resist… can't fuck... won't stop… he fucks me...

His rough hands gripped her thighs, spreading her wide beneath him.

he's in me

The weight of his body against hers was unbearable yet intoxicating, each savage thrust sending shockwaves of forbidden pleasure through her.

Mine… no, his…

Her thoughts blurred with the fevered heat coursing through her.

his cock.... his cock throbbing...

The King's face shifted in and out of focus, the edges of the dream swirling like smoke.

Deeper… harder…

She couldn’t think, couldn’t speak. Her body was no longer hers, consumed by his strength, her hips arching into him, desperate, needy. His cock was filling her whole torso, becoming her insides.

In the waking world, her body subtly shifted in sync with the dream, her chest heaving as her back arched into the bed, the silks clinging to her curves. The crimson tunic twisted around her as her hips bucked into the air, the sensation building to a fever pitch.

Amidst the dim flickering of the night's remaining candles, a female slave slipped into the Empress's room, a shadow in the candlelight. The slave's eyes glinted as she approached, sword held low, silent as a wraith. She watched the Empress writhing in the sheets, the most powerful woman in the world so vulnerable, her dreaming face flushed with a mix of pleasure and oblivion. For a moment, the slave was transfixed.

I need… more…

The Empress' dreamself whispered "yes yes", her lips parted as she bit back a moan. The Barbarian King thrust again, harder, deeper.

Yes… almost…

Her mind spiraled as she felt herself pushed to the brink, the ecstasy burning through her.

Take me… fuck... inside.... everything.... oh gods i'm....

At that exact moment, the slave struck. Her blade plunged deep into the Empress’s sternum, right between her breasts, sinking through muscle and crunching through bone, a sharp intrusion that shattered into the dream.

In the Empress's mind, the barbarian's cock had suddenly extended up inside her abdomen and ejaculated into her heart, decimating it.

too much!… hrrnng! oh gods…

his fluids in me, on me...

She gasped in the dream and grunted in reality, her body trembling violently as her climax tore through her, intense beyond anything she had ever felt. Her eyes flew open wide as she jerked up awake, her vision swimming in a haze of euphoria and confusion and pain as her womanhood contracted in orgasm.

...he’s… still…

She wasn’t looking at her dream lover. She was staring into the cold, merciless eyes of her slave, who stood over her with the hilt of the sword still gripped tightly in her hand, a ravenous grin on her face.

The Empress's lips parted in a silent scream, her hand weakly reaching up as she tried to inhale, trembling, fingers brushing the slick warmth spreading over her tunic.

....what...not… real…

Her chest shuddered as her body reeled, a strange, sickening pleasure still emanating up from her spasming pussy. Blood bubbled at the corner of her lips and she choked out a gasp, unable to process reality.

"My King sends his greetings," the slave spat, speaking the barbarian tongue.

Reality set in.

"nn-nngh hrrk...." the Empress could only grunt and choke, like a slaughtered animal.

Her vision unfocused, but her eyes remained wide, staring at the slave with a mixture of disbelief and perverse intimacy. Her body twitched, remnants of the dream rippling up her stomach and down her thighs as her muscles gave out.

With a low, wet rattle of crazed frustration and denial she collapsed back onto the bed, her limbs going limp, her tunic now soaked in blood. Her gaze fixed on the ceiling, vacant and unseeing. The slave looked down at her with relish.

She then withdrew the sword, wiping it clean on the Empress's silk sheets before slipping back into the shadows. The slaughtered Empress lay still, her death stare reflecting a strange, haunting mixture of devastation and orgasmic afterglow.

Thus it was that the Barbarian King had fucked the cocky Empress in two ways; his virile presence had penetrated her mind to dominate her fantasies, and her own slave - truly, his slave - had impaled her body, ending her forever.
