Exterminatrix

“Is this okay?” Castro stops to ask when I moan a second time and bite my wrist to stifle the sound of my need. I glance down at him and go completely still.

“What is that?” I ask, pointing to Castro’s face, or more specifically, the cock that’s emerging from the seam in the pouch beneath his chin.

“My secondary cock,” he replies in a low voice. Castro looks almost sheepish, ducking his head as though I won’t be able to see it. Which…good luck. It’s fucking huge. The rounded head is covered in small, soft spikes, tapering to a long, almost translucent shaft covered with a spiraling row of purple filaments that flutter as though they’re tiny creatures with their own desires.

If that’s his secondary cock, what’s the first one like?..

Shit. I’m not sure if the other one will be bigger, but I do know I want this one to stretch and fill my aching pussy. Right now.

“You need to fuck me with that. Immediately,” I say. Castro swallows, the filaments on the spiral of his cock flickering at my words. “I don’t know what kind of monster jizz you’re carrying around with you, but I’m clean and on birth control.”

Castro looks at my pussy, the dampness of my need slipping down the crack of my ass. “Are you sure it’s going to fit?” he asks, not taking his eyes from my pulsing sex.

“It’ll fit, Castro. Trust me.”

Castro swallows again as though trying to trap his uncertainty in his throat. I reach down and wrap my hand around his cock, sliding over the large but pliant crown, the soft spikes tickling my palm. My core clenches imagining what that might feel like against the walls of my pussy. Castro shudders, pressing his eyes shut with a moan as a bead of precum slips from the head. I pump down his shaft and back up again until Castro opens his eyes and meets my gaze with a look of desperation that gives him a wild, reptilian beauty.

“If it feels this good now, imagine how much better it will be when you enter my cunt,” I whisper. When Castro finally gives a shaky nod, I guide the head of his cock to my entrance. “Take it slow.”

Castro’s secondary cock settles against me, and I encourage him to keep pushing by stroking the soft scales of his muscular arm. The pressure builds with delicious heat until finally his cockhead pops into my pussy, filling the entrance of my cha

“Gods above,” he grits out, sliding a little deeper, just a bit at a time. “You feel incredible.”

“Just wait until you start thrusting,” I say with a chuckle that sets off the purr in his chest. The vibration of it seems to flow up into his sex, sending the filaments fluttering against my i

“Is this okay? I don’t want to hurt you,” Castro whispers, his breath warming my skin.

“You’re not. Trust me, I can take it.”

“What should I do next?”

With every word he forms, the cock buried in my pussy moves against my walls, a subtle shifting that sets my blood on fire. I resist the urge to groan, knowing he needs me to guide him with clear instruction so that his first time is worthwhile. A pang of guilt hits my heart as I realize this first time might be his last, but I swallow it down as he repeats his question and the flexible spikes of his cock stroke my G-spot.

“Pull back and push in,” I say, and he starts to pick up a ginger, rhythmic motion, pulling out and pushing back in just an inch or two at a time, “Good, Castro. That feels really good.”

I look down at his face between my legs, his secondary cock sliding in as he gives me an unsure but relieved smile. I reach down and grip a fistful of his hair, guiding him in longer, deeper strokes.

“Like this?” Castro asks, his voice gaining a little steadiness as his confidence grows.

“Yes. Now go harder and harder until you fill me with your fucking monster cum. And use that tongue on my clit while you’re at it,” I reply, and then I tilt my head back with a gasp as he does exactly what I demand of him.

The pace remains slow at first, and Castro shudders with the new sensation of filling me with his sex. The bulbous head of his cock slides to my entrance and pushes in again, burying so deep he touches places I’ve never been touched, even by the biggest human men I’ve been with. The soft spikes on the crown drag across my walls with every stroke, and the filaments caress me in their wake with soft, fluttering touches. Castro’s forked tongue worships my clit, swirling and lapping, sometimes dipping toward my entrance to slide through my arousal before coming back again to tease out my pleasure.

But the languid pace doesn't last.

An animalistic need takes over. I feel the tension in Castro’s taut muscles wherever they touch mine. His purr becomes a growl that rumbles in the depths of his chest as his strokes become thrusts and his feral nature takes over.

And then he’s pounding into me, railing me into the ground.

Castro hooks his hands beneath my thighs and raises my ass from the floor, hitting as deep as he can with every punishing stroke. His tongue flickers against my clit and my orgasm starts to take hold, warming my core with an explosion of sparks and turning my limbs boneless, my mind blank. My pussy clenches around Castro’s cock as I come apart under waves of drowning, consuming pleasure, and he roars my name as a torrent of cum fills my sex with liquid heat. He doesn’t stop pumping, even when his body shudders uncontrollably, even when his grip loosens around my legs. Still he slides and pumps and fills me, and my first orgasm subsides only to come again in a second one, even stronger than before. My back arches and I cry out and still he thrusts, and he doesn’t stop until I’m so filled with his cum that it’s dripping down my ass and pooling on the blankets below me.

When it finally stops and we’re both little more than raging heartbeats and ragged breaths, Castro pulls out to rest beside me, caressing my skin with his scaled fingers as his secondary cock gradually slips back into his seam. His claws rake across my arm, but never hard enough to draw blood. They shift a tickling pattern over my skin, my goosebumps rising to meet every touch.

“You taste so sweet,” he whispers, a single claw trailing a line down my arm and back up again. “I never knew a human would be so delicious.”

I say nothing, losing myself to thoughts of what Castro’s monster cum might taste like as his touch slows, dragging across my shoulder to follow the line of my collarbone. My pussy clenches. Even though I’m still full of his spend and I’ve just had two intense orgasms, I want more. In fact, it feels like I need it, a need that goes beyond my control. And as Castro’s claw trails down my chest to circle my tightening nipple, I think I’m not the only one who feels that way.

The smell of desire ignites in the air, the mysterious scents of rare and precious oils, of night blooming flowers. I take in a deep, shuddering breath.

“So, if that was your secondary cock…what’s the first one like?”
