A Gratuitous Sentient Being Scene

Nikki's tongue lightly caressed my lips, and when I opened my mouth, slid inside with a rapacious passion. The kiss continued to intensify as I kissed her back, our mutual breaths coming quickly and shallowly between harder and faster lip locks. It felt wrong somehow, as her mouth pressed against my transformed face, lifting my jowl carefully and allowing her tongue to caress the underside before pulling my lengthy tongue into her mouth again and sucking contentedly.

"Oh, yeah..." Nikki moaned as we finally broke apart.

"Wooof..." was the only work that I could manage. My brain was still fogged with the pleasure of her kisses along my new tongue, and I felt the soft pressure of my sheath retracting slightly from the deep pink of my transformed penis.

"Ok, I'm really fucking horny now." Nikki nearly snarled the words, as her hands moved to stroke along my sides, and scratch deeply into my ribs. The contact felt incredible, and another motion of my cock slipping free from its constraining sheath brought exquisite pleasure. I already knew what it felt like to mate with this gorgeous woman, and now... she didn't care what form fate had given to me. She wanted me again, and her lips on mine as her hands continued to stroke along me were magical.

My mind barely registered what she was saying, still reeling from the aftermath of the kiss. The tremors of anticipation came back, this time stronger, and in waves that caused the pads of my feet to shiver slightly. I had to consciously think about it to not immediately hop upto her and take her like I desired, despite her clothed state.

"Oh FUCK! One second," Nikki jumped away from me, and headed for a cabinet on the other side of the room. "Don't worry big boy, we're still going to play just..."

I turned around on the bed, making myself comfortable. That almost felt, no... needed to adjust again. There. There, that was much more comfortable.

"FUCK!" I looked over at Nikki, who was holding a small note and cursing. "Fuckfuckfuck. I HATE Charlotte sometimes! I hate her, HATE HATE HATE!"

I cocked my head at her, confused. I wasn't used to seeing one of my mistresses angry, and when it happened I was usually certain that it was only seconds before I was kicked out.

Nikki gestured to the door, and the large apartment beyond. "The bitch borrowed our emergency condoms and left me a NOTE. Couldn't be bothered to TELL me... ARRGH, did she at least tell you?"

I nodded my head happily, and added a helpful bark of encouragement.

"Did you bring one today, boy?" Nikki asked, hope welling in her eyes.

I wagged my tail again, shaking my head and panting happily.

"Brent look, I really, REALLY want to. OK?" She smiled and ran an appraising eye over my now fully exposed cock, thin and softly pulsing. "I mean, you're really cute right now, and sweet in a total shouldn't be even THINKING about this kinda way."

I was relieved that my current awkwardness and physical form wasn't a total deal-breaker.

"But there's a major problem." Nikki's face took on a serious cast. "I'm not on the pill. And when I get THIS horny, well, it usually means that it's been two weeks since my period. You remember what happened a year ago on our first time. So... "

I looked at her with a disappointed look.

"Well, we can do other things." Nikki grinned, and suddenly grasped the lower hem of her t-shirt. She jerked it up over her head, revealing the light olive skin of her upper body. She was enchanting, with a slight curve to her belly that showed where she had carried our first child, and two beautiful filled out breasts capped with soft brown nipples that were currently erect.

"I just have to keep my pants on." She swayed towards my, and ran her fingers behind my ears. She leaned in for a kiss, and again we made out softly, my tongue caressing the inside while she continued to stroke and rub at my flanks. I couldn't resist the taste of her, and allowed myself to lick against her chest, her neck, her breasts, My tongue fluttered against her nipples, and I felt the soft taste of an occasional droplet of soft sweetness.

Nikki sank onto the floor and we continued to kiss and touch each other. The tremors in My body ceased, but they seemed to pass into Nikki, who shuddered and moaned harder with each passing moment. Finally she broke off the kisses, and her hand went to the corner of my jaw.

"Lick me here." She whimpered, pushing my head down so that it lay at the juncture of her legs. Immediately I rubbed at the fabric of her jeans, feeling the giving softness beneath. My erection pulsed in the air, and I could feel the soft flow of moisture flowing through it as I took in her scent. She was hot, aroused. Her body was primed for mating but I tried not to think of the uncomfortable pressure and the growing urges for consummation within me, just concentrating on giving her pleasure.

"My pussy..." Nikki gasped, the trembling in her body increasing, "Touch my pussy."

For an instant, I simply continued to rub at the material of her jeans, before she made her request clear by unsnapping her jeans and pushing them down enough so that her panties were exposed.

"It's fine... I'll just leave these on." She whispered, before leaning back again, this time nearly panting and closing her eyes tightly.

Unable to resist the chance to delve into her most intimate place, I slid my tongue down again, first feeling the soft cotton of her underwear, then the firm giving material of the elastic. My tongue pushed on further, and I soon felt the tight, downy curls of her lower hair.

Nikki purred beneath their kisses, her hips moving against my muzzle. My tongue moved onward, until I felt the first folds of her tangy pussy. She was very moist, with a heat that engulfed the tip of my tongue even though it merely pressed against her warm yielding flesh.

I found myself panting, missing the sweat that used to form on my brow from sheer excitement as my tongue pressed against Nikki's swollen, ripe pussy. It was a bit awkward, since my head was now bent at an uncomfortable angle. but the sensations of taste more than made up for it.

"I want more," Nikki whispered, both of her hands moving to her pants. "It's OK, as long as I keep my underwear on..."

The clasp of her jeans opened, and she raised her hips, as she slipped her pants over her gorgeous ass and down her slim, elegant legs. A moment more, and they joined the growing pile of clothes on the floor.

I eagerly allowed my tongue to slid up and down the length of her sopping slit as the cloth came away and she held her legs up, allowing me to fully explore and take in her scent and excitement.

"Mmm..." Purred Nikki in response, her legs falling apart lewdly. "I want to feel your tongue inside me."

I pushed forward, my mouth open happiily and slid my tongue along her crevice, finally finding the tight ring of tension that signaled the entrance to her body. I pushed, and felt my tongue coated by her wet, welcoming lubrication. The aroma was intoxicating, signalling how eager and primed her body was for our joining.

"Yes..." She growled, humping her hips up at my probing tongue. I could see her flushed features, and the way she moved her body against me convinced me of her excitement and eagerness.

"Oh, fuck... Stop! Stopstopstop!" Nikki gasped, pushing my muzzle away. "I don't want to come like this..." Her breath was heavy and ragged, a look of pained lust on her face. "Do you think... you know when you're about to come right?"

I nodded, knowing the signals of this body. I'd gotten used to it, over the time. how it felt, how the body reacted when reaching it's peak.

She licked her lips, looking directly at my crotch. She raised her eyebrows as she did. I quickly got the hint, this caused my aching erection to push out a little further, the full length now loose of it's constraints, pointing almost directly at her.

Nikki turned around, revealing her body to me. Unable to take any more of her teasing, I jumped up and my front legs grasped around around her waist.

My desire for her was expressed in a soft expression of lust which caused her to lean forward and place her hands on the floor. I breathed softly in her ear, and was gratified by a small tremor that ran through her body.

"Promise me something." Nikki groaned, grinding herself back against me and sending shockwaves of pleasure through my cock, which pressed against her ass. I humped my hips furiously, trying to find the connection

"I'm not safe," she reiterated, "So you can't come inside me. Promise me you'll pull out."

For a few moments, we merely remained like that, touching and caressing. Then I felt the first soft caress of the lips of her engorged pussy.

"We can fuck, but you can't come inside me. Promise me..." Nikki warned again, her hand snaking down to grasp the shaft of my pulsing cock. She smiled as she felt the length, and breathed out softly as I nodded at her. Slowly, she guided me between her legs. The frustration and desire was amplified and I myself to fight the instinctive urge to ram forward.

"Shhh... I know, baby. You feel so good..." Nikki groaned, sliding my cock up and down along her slit. She guided my aching member to her entrance. "Go slow, please..."

I nodded again, pressing my hips forward. I could feel her body beginning to surround the wet pink flesh, and her pussy lips spreading around it deliciously. Her heavenly pussy practically was begging me to ram it home, but I resisted the urge, concentrating on keeping calm. If I rushed, I'd definitely break my promise.

"Oh, god, I've never done it with... someone like this before" Nikki groaned as the soft bulge at the base of my cock pressed carefully against her lips,. "It feels so much better with the soft fur..."

I growled a deep primal utterance. The thought that I was the first well... that this was the first time anyone had ever been inside her like this made it even better. It was taking every bit of my self control to avoid spurting into this beautiful woman already, and all my body wanted to do was to let go, and seed her fertile womb. I felt the urge to ram it in, to completely make her my bitch...

We moved slowly, both of them enjoying the raw, naked feeling of nude flesh. As I thrust myself against her back, I couldn't help but howl with triumph and she suddenly began to breath heavily and pump her hips up at me.

"Oh shit. Don't come, Brent Just a few more seconds. Oh... Oh... I'm coming..." She gasped, her pussy clamping down on my cock, and her ass ramming backwards, impaling herself fully on my straining rod. She humped against me shamelessly, grinding her clit along the thickening shaft. I growled again as I felt my balls tightening through her orgasm, and the various glands in my lower body getting ready to jettison their load directly into her. Deeply sheathed in her body, I couldn't stop the primal urge, and thrusted, again, and again. Only a few strokes, and I was already ready to blow it. It was time for me to pull out, I regretfully realized. I pulled back as I felt my shaft filling with even more blood.

"Yes..." Nikki panted as the last waves of her orgasm passed. "Get up..." Her legs spread apart widely, to facilitate my exit from her sated body.

It is at this point that I encountered a problem. Up until now I'd never even thought about trying this with my current equipment. Which is why, during my first attempt at coitus interruptus, I was shocked to find that he could not pull out of Nikki's sweet little pussy. The bulk of my penis was held fast inside her, by the thickening knot of cock which lay directly beneath her pubic bone.

"Oh god, "Moaned Nikki, still in the last throes of her orgasm, "You're filling me up! It's getting... Oh god... Bigger!"

I whined... pulling back, and attempting to flex his my and pull myself free. I was tied to her, and I realized that the throbbing pulses through me, the amazing feeling... I was already coming!

"I can feel it pulsing in me!" said Nikki, realizing at last thatI wasn't pulling out. "It's swelling! Take it out!"

I pushed back with every appendage I had. It pulled heavily on the base of my cock, held fast inside her body, twitching madly. I couldn't do anything but pant in sheer exctasy.

Unfortunately for Nikki, the frantic attempts to remove my cock had the side effect of rubbing against her already over stimulated clit. Her nervous system, already primed by the incredible deep penetration, went over the edge into a second full blown orgasm.

Her pussy, filled to the brim with male flesh, convulsed along the entire length of my swollen Cock. The first few ripples along her walls sealed her fate, as my aching balls continued to disgorge their cargo of semen, which raced through my lower body, bringing a howl to my lips in triumph as I claimed my bitch.

"Oh no..." She half sobbed through her climax. "I can feel it... no..."

Her protests were futile as nature took over. The first streams of semen were still speeding through me into her and with a final twitch, splashed out against her cervix, coating it thoroughly.

I groaned with the of the orgasm I experienced, feel jet after jet of his sperm being coaxed out of my shaft by the motions of Nikki's pussy. Unaware of how useless the action was, she had been rolling her hips, trying to separate her body from mine, but she had only succeeded in forcing even more come from my body.

The swelling in my cock and the sensations in the rest of my body were to much, and I found myself slumping down on Nikki, who still moved, trying to extricate my cock from her body.

"Get it out..." She whimpered against the ground as she pushed against my hip. "Oh god, you can't stay in me. We have to get it out!" Nikki wailed, truly feeling the enormous knot that tied us together.

"I thought... they said it was a myth that girls could get stuck." Nikki groaned, moving her hips again, which ended up causing pleasurable sensations in both of us. "Not that I'm complaining, about... how... good this feels... " she amended, " But it's not your COCK I'm worried about. It's your sperm."

Nikki was right to worry, for deep inside her at that moment, millions of sperm cells were swimming into the secret recesses of her body. For no matter what my form had been, my seed was still compatible with her. As the two of us lay there, experimentally trying to separate, several thousand of them entered her Fallopian tubes. And, just as my cock slipped free of her thirty minutes later, still very large and wet, a single sperm cell penetrated the outer layer of her just released egg, and fertilized it. The hormones and desires brought forth a deep pulse in her lower body, and a second egg was quickly released to the pack of hunting seed which wasted no time whatsoever...

She was to bear a litter, even as she wiped her thighs clean of the flood of semen which had spilled down her legs after my knot had come free.

"Oh fuck." She moaned, rubbing her hand over her stretched pussy lips. During the time she had been tied to me, she had suffered numerous aftershocks, which led up to a final, devastating orgasm. "I can't believe that actually happened."

"I guess I should have thought of that..." Nikki sighed, looking down at my deflating, but still large cock, with it's knot still obvious. "Weird, yes. Hot, Yes. I just better never try to have a quicky with you..."

She brought her arms around me, breathing heavily, and we kissed gently, both of us still reeling from the exhilaration of our deep and total mating.

[Author's note: Not tagged, nothing explicitly said, and Brent Clearly is consenting with what's going on and is fully aware and sentient, as well as sexually mature as is Nikki. I think this fully satisfies the Harkness Test, and is even mostly consensual.]
