The Burning Lust of an Incubus

I had talons, and an extra weight on my forehead meant I probably had horns too.

The realization triggered some kind of instinct inside me and all my inhibitions burned away in the wake of the heat that pumped through me.

A deep, rumbly growl emanated from low in my chest. Annie squeaked when my grip on her ass tightened, but I was careful not to break skin. I maneuvered her like a ragdoll so she was face down on the bed.

"Oof!"

She was even smaller and lighter than before! Distantly, I saw the deep crimson of my skin contrasting with my bimbo's glittery pink tan and my dull black talons gently dug in her flesh. My bright red cock smacked onto Annie's back, reaching almost to her shoulder blades.

"Ooh~ Did you get even bigger!?"

I grunted in affirmative and wound back to line myself up properly with the glistening hole between her legs. Her lips stretched to allow me in, the slick folds tightened on my shaft like a rubber glove.

"You feel so hot inside me Mason!"

Her depths were oddly cool as I drove myself in, like a lukewarm bath after a hot tub. Not unpleasant, just odd. Annie welcomed my entire shaft inside her, letting out little gasps and squeaks as I pushed, until my hips were cushioned by her ass cheeks and I could feel her erratic breathing on my cockhead.

"Ahhn~ I c-can feel you pressing against my diaphragm! Unnf! It's like my whole body is made for your dick!"

My cock dragged its way out of her greedy pussy until only the head was left inside. Annie sucked in a few ragged breathes in relief and anticipation.

"Do it! Fuck my hungry little pus—aaaAHhng~" Her shriek was cut off in a breathless gasp that was drowned out by the clap of my hips slamming into her ass. Her flesh rippled like jello at the impact, from her bouncy ass up to her pillowy tits wobbling beneath her.

The sturdy wooden bedframe creaked and whined from the **** of my relentless thrusts. The walls were already scratched and gouged down to the brick. I didn't have enough brainpower to do more than acknowledge it as part of the background.

Annie seemed to enter a kind of mediation, breathing out as my cock entered her and breathing in when I left. Or maybe I was using her body as a bellows? The trail of drool and incoherent babbling coming from her head left me leaning towards inconclusive. More testing needed.

I was like a machine or a dumb beast, doing the same movement over and over again, occasionally driving in harder when Annie squeezed down in orgasm. My own orgasm came and went without me truly noticing, a steady flow of fluid filling Annie's pussy, a bare trickle all that could escape around my shaft.

CRACK!

With a cascade of cracks the bedframe gave out like so much driftwood. Neither of us reacted, simply continuing to fuck atop a pile of twisted and splintery wood, the shredded mattress and bedding the only protection.

I did not, could not stop. All that mattered was putting my stiff dick inside a wet hole.

"Mason! What the hell? I've been gone less than ten minutes!" A very faintly synthetic voice finally broke my concentration on Annie's bouncy ass and I turned to look at an exasperated Sam holding a tray of sandwiches and drinks.

"Sam?" The voice that came from my throat was deep and gravelly, like my vocal cords were made of stone. My hips hadn't stopped thrusting, but I did slow down.

"Hey there, Mason. Cool horns, I think we had a talk about this exact thing the other day." The android set the tray on my desk and put her hands on her hips, one foot tapping the ground as she took everything in. "Okay big guy, let's see about giving Annie there a break, eh?"

She stepped forward carefully with her arms held to her sides. The fear I saw in her movements snapped me out of the trance I had been in and I pulled out of Annie with a wet sucking noise. The bimbo rolled to her side with a tired whine. My dick somehow got even harder when I saw her rounded belly and the river of cum pouring out of her.

Had I just done that in a few minutes? I looked around my destroyed room and felt a little vertigo at how small everything was. One of my horns tapped against the light fixture on the ceiling and my desk just barely passed my knees.

"Goddamn, you really did a number on her. She looks six months pregnant!" Sam watched Annie lazily eating handfuls of my cum with a dizzy smile. The android dragged her eyes away from the sight and back to me. "Are you back with us?" She asked.

"Yeah." I rumbled. "I'm back." I ran a hand over my head to feel my hair between my pair of curling horns, relieved I still had it. I suddenly had even more sympathy for Asmodeus.

"Are you stuck like that? I-i mean you look super hot as a hormy demon, but I don't think you can fit through the doorway." Sam put her hand on the top of her head and kept it level as she swung it toward me. She stopped with her hand just below my sternum, her tongue flicked over her lips as she continued measuring me with her eyes. "Your dick is 18 inches long! That lucky bitch..."

I ignored her horny mumbling for a moment to close my eyes and focus on the flame that was burning inside me. It was a deep crimson, burning bright and cheerful. Steady without consuming any fuel I could see or letting off any smoke. Like Magic.

Looking closer, I realized it wasn't a single flame in a physical location. Faint trails of fire spread throughout my entire body like veins or roots, growing brighter and dimmer with every breath. With a muscle that was not really a muscle, I...pulled on the flames. Pulling them inward to the furnace inside me.

I opened my eyes to my normal human skin and Sam staring at me with wide eyes, her head reached just below my shoulders again.

Grinning, I ran a normal human hand over my hornless head and spoke with a normal human voice. "We have a lot to talk about, have you ever heard of a demon named Asmodeus?"

My dramatic hook to our conversation was undercut by my empty stomach grumbling.

Sam giggled at me. "I'm sure you can tell me all about it while you eat the sandwiches. One was supposed to be for Annie, but..." We looked over to Annie to see her stomach hadn't shrunk one bit while no cum was pouring out of her pussy anymore. "Yeah, I think she's full." The satisfied bimbo began to snore.

I started munching on sandwiches and explaining everything that had happened after the Book knocked me out. I looked around my destroyed room again, glad we'd convinced Dad and Stella to go out tonight.
