#5 of Mongol and Alexei


Once she'd finished showering, she began wandering around the castle, looking for her mate and master, Mongol.

Then an announcement came over the loudspeaker, It was mongol, who struggled to contain his excitement, "Alexei, please report to lab 53X."

Her tail wiggled in anticipation as she grinned, before floating along quicker and making her way to the aforementioned lab. Once at the door, she knocked it a few times, barely containing her excitement.

Mongol opened the lab door for her.

Alexei entered and smiled at him; "Hey, cutie~! What's this about?"

A massive smile was plastered across his face, "I have great news!" He went over to her, hugging her.

Alexei smiled wide and hugged him too, giggling; "Great news?! What about? Go on, tell me!" she urged.

"I have successfully figured out a way to impregnate you.

Alexei's eyes widened; "Y-You do?!" she exclaimed, then she grinned widely, hugging him tighter and jumping for joy; "Oh, yes! Thank you thank you thank you, Mongol!! Now we get to have kids!" She was so happy her eyes were a little wet, her heart fluttering a bit.

"Well, we have come up with three different ways to accomplish this, and I would like to know what way you would like to be impregnated."

"Three different ways?" Alexei wondered, getting a hold of herself and wiping her eyes, sniffing a bit before nodding and standing still, eyes serious. "Alright, tell me." Inwardly, it was hard to remain calm- she was excited and nervous at the same time. She'd already determined that she'd wanted this, but that didn't come without its worries either way...

"So, the first way I developed was this, a surgical procedure where you would be implanted with a fertile cell, and we have sex, so that I may fertilize it, this impregnating you." He reached over to a flask of purple liquid. "And this is the second two," He swirled it inside of the flask. "It is a fertility enhancing agent, this would allow you to temporarily release fertile cells, and there are two methods of delivery. Orally, and..." He smiled at the second one, "Tentically."

Alexei looked at him with a widening grin as he went on, then said, "Duh, tentically! Is that even a word? Who cares, it's the most exciting option, so let's do that!"

Just the thought of being tentacled made her minutely shiver; she'd remembered when Noiris had done it to her, and she'd enjoyed it then. THat the end result would be a chance at having a child was all the better to her.

Mongol laughed, "Then I'm glad I made more than just this." He set it down. "I had a feeling you'd pick that, so I went ahead with it. Now, if you'd join me in the 'sexperiment'." He winked.

She smirked and crossed her arms under her breasts; "Hehe. You and your puns..." she chuckled, then floated up a bit off the ground. "So. How are you planning to go about the tentacles? Did you, like...build some artificially or something?"

Dramatically he flipped the cover off a large red button. "I've always like big red buttons." And equally dramatically pressed the button, making a horn blare. BWAHM. and several large, silver tentacles came from the ceiling, floor and walls. Pulling a mic to him, and tapping it to test, "These-" It gave an unpleasant feedback, then he spoke again. "Sorry. These, are only the first round."

Alexe's ears folded on themselves a bit at the feedback as she grimaced, but she recovered quickly enough as she looked over the tentacles with wide eyes; when he said they were only the first round, she looked at him incredulously. "F-First round? But they're everywhere, how is that possible?"

"This is how." Five of them lunged forward, their heads opening, and going over her arms, legs and tail, restraining her. Two more approached, one to her pussy, another near her mouth. "Sorry about the restraints, but once this begins, I think you will like them."

Alexei gasped in surprise as she was held captive by the tentacles, not expecting such a move at all- though she should have. She wriggled, struggling just a tiny bit, but only out of wanting to see how sturdy these tentacles were. After a few moments, she sighed and settled down, smiling at the tentacle in her face. "Why, hello there~."

The metal that their outsides were composed of was a mimetic polyalloy, giving them an almost organic look. Their heads began to morph and reform, revealing a tube inside, before reforming into a model of pointed penis. "Does it look familiar?"

Alexei smirked; "Hell yeah it does. Deliciously so..." She looked at the tentacles around her, her tail- restrained as it was- giving a little anticipated twitch. "Can...they all do that? That would be amazing if they could."

They were modeled after his own, smaller in size of course, Mongol couldn't very well have her experiencing something larger than him if he could control it. "Sorry, not all, but enough can." He smiled.

Alexei looked at him with a sly glint; "You know what? That's amazing anyway. YOU'RE amazing, Mongol. Can't believe I've lived my life without you up till recently." She looked at herself a last time, then demanded impatiently, "So, we gonna do this or what?"

"Nor do I." Smiling, he pulled a lever, and the tentacles plunged into her, rapidly fucking her hard, fast and deep, the metal of the tentacles head in her tunnel undulating and moving as it thrust in and out to increase her pleasure.

Alexei's head was thrown back with a loud gasp as she was penetrated, trying to writhe and wriggle to express her emotions and feeling as she was pumped into like that, but achieving nothing instead. Those tentacles had a very good grip of her, evidently. Instead, her chest- and consequently, her tits- heaved and bounced as she took deep breaths, trying to remain focused as she was fucked, though it was difficult here...

"Would you like some 'assistance' for your 'pokeballs'?" Mongol smirked, flipping a switch, making two more, smaller ones approach her breasts. He also pulled another lever, making the paneling of the tentacles retract, showing their clear insides, with the purple fluid flowing through them.

"Gggh..y-yes..." she groaned, noticing the tentacles approach her breasts; "D-Do as you p-please..! Ah..hah...." She also saw the purple liquid within the tentacles, and her cheeks let out a deep blush; all of that would be going inside her, soon enough. She privately wondered what it would be like to have it all over her as well, but kept that at the back of her mind- what mattered was that the fucking in her pussy was making her even wetter, feminine fluids already dripping to the floor.

The two free tentacles, not having any liquid in them, took the form of suckers, and latched onto her breasts, pushing and pulling as they sucked, alternating, so when one pulled, the other pushed, small fingers of the alloy forming, massaging her tits. while inside the alloy burrowed deep into her, past her cervix, the pumps audibly activating, and the liquid beginning to flow, then one thrust into her mouth.

Alexei let go and moaned now, the moan muffled by the tentacle entering her mouth; instinctively, she started sucking on it, conscious of the liquid moving through the tentacles on its journey into her womb. The tentacle ramming through her cervix earned particularly gratuitous moans from her, but the tentacles playing and sucking at her tits would be getting an interesting surprise as they carried on their work: her nipples perked in no time at all, and soon began leaking milk as they did before.

"M...Mongol...this..amazing..." she managed to get out around the tentacle in her mouth before letting out a higher moan, arching her back from it all.

The tentacles attached to her breasts began to suck out her milk, it visible as it traveled along the clear inner tube and into the wall. The tentacles then began to pump their load into her, starting with her womb. The purple liquid began to be pumped into her womb in massive amount, the tentacles bulging out from where a dose of it was as it was delivered to her womb.

Alexei moaned deeply as her tits were steadily sucked of their milk, the feeling quite pleasurable, but not quite the same as the feeling of the liquid entering her womb. Just watching it travel along the tentacles was enough to make her feel giddy; the feeling of the liquid as it bulged in the tentacle on its way to her womb, bulging out into her vaginal walls as it did so, made her shaky enough but when it promptly burst inside her in frequencies, and in massive amounts, it was all she could take not to lose her cool.

Well, what little cool she had left; her hips and body shook, the liquid audibly splashing and splattering inside her repeatedly, her stomach beginning to grow in size little by little as her moans got louder.

The same liquid then began to leak into her mouth, dripping slowly before increasing in flow.

She let out a last moan before she was forced to begin swallowing the liquid, closing her eyes as her body twitched a bit where it could; her tits had actually shrunk a tiny bit, though they hadn't stopped offering the sucking tentacles milk. Some of said milk had managed to escape the tentacles and was coating the undersides of her breasts; the whole time, her pussy quivered and twitched violently around the tentacles inside her, her stomach showing a more visible bulge now as the stuff just kept pouring inside. It was all so pleasurable her mind was being numbed and she could only think of how much ecstasy was flowing through her veins...

It took a lot of restraint for Mongol not to fap to this. With the first tentacles emptied, the one in her mouth pulled out, but her pussy remained plugged by the tentacle, continuing to pump her full as it slowly pistoned her pussy.

Alexei's moans became slurred and drunken, her eyes slowly opening but only remaining half-closed as she looked up, mouth hanging open when the tentacle there pulled out; some of the liquid it had deposited inside her leaked from the side of her maw along with a copious amount of drool.

Her abdomen in the meantime was bulging more still, there was so much liquid in her womb now that it had gone past its usual containment area- she was being inflated and she was certainly loving it, pussy juice squirting from her every now and then as proof as her eyes rolled from the pleasure of it all.

The tentacles; purple liquid began to run out, evident by there being none in the tube anymore. Mongol returned to the speaker, "Well you certainly cleaned us out."

Alexei twitched once or twice at this, her stomach gurgling a bit what with how absolutely full she was, then before she could stop herself- not like she could anyway-, she climaxed with a moan, Mongol's words sailing right over her head as feminine cum ran down her legs and splattered to the floor, falling limp in the tentacles' grip aside from the odd continued twitch or two.

There was another beep, and the tanks were empty. "Alright, that's all of it, now begins the second part." Mongol said, leaving and walking into the experimentation room to join her.

He'd find her still limp where she was, looking misty, stomach bloated, but she had a ditzy smile on as she saw him approaching. "N-Nice...little machine you g-got...here, Mongol..." she slurred. Her eyes took on a sly gleam, however; "Th..they're nothing compare t-to...to you, though...mmm...."

"I wouldn't have made it any other way." Smiling, the tentacle pulled out, but the liquid all stayed inside her.

She groaned and nearly collapsed as the tentacle pulled out; she was amazed the liquid didn't fall out of her. "Must be nanomachines," she murmured, then looked at him with half-lidded eyes. "Ready to make babies?"

"Nope, you're just too tight for it to come back out. Now, your you prefer I just stick it in you, or have some more fun?"

She raised an eyebrow at that, standing properly straight despite the awkwardness of it due to her belly. More fun? What could that entail..?

"What do you mean by that?" she asked, tilting her head in interest

"Blow me?" He asked, "Or just impregnate you right now?"

Alexei smiled and simply got down on her knees in response; "I think a little warmup from you wouldn't hurt anybody," she purred, caressing his rod teasingly. "I certainly wouldn;t mind another taste~."

Smiling, "Alright then."

She didn't waste another second, and bending forward, she began sucking his tip, looking up at him with innocent eyes and a servile attitude, tail waving behind her gently as the tip of her tongue fluttered briefly against his shaft's head every now and then.

He looked lovingly at her, his meat going deeper into her mouth, groaning when her tongue brushed his tip. His tail wrapped around hers.

Her tail squeezing around his affectionately, she closed her eyes and took more of his meat in, sealing her lips around the organ and making more sucking motions, her tongue wrapping around that shaft sensuously. 'Mmmm...I'll never get tired of the taste....' she mentally groaned.

"And I am glad for that, because I will never tire of you." He pushed deeper, his cock throbbing in her mouth.

Alexei decided to forgo wasting time and just took him into her throat, obviously deepthroating him as she groaned again- part of it was deliberate, to create pleasurable vibrations. She sucked and made swallowing motions, her throat massaging his cock in that way as her tongue continued to wrap and wring itself along his shaft.

His hips shook, it felt so good! She had been made for fucking, and she was made well. His cock made a noticeable bulge in her throat each time he thrust into her mouth.

She sucked on him harder, taking in as much as she could, not minding the bulge nor noticing it, just utterly focusing on what was important- to her, anyway. For added effort, she decided to try something else- one of her hands reached under her Flygon master, and began fondling his sack.

Her fingers were great, their odd shape massaged him in ways other females couldn't. Groaning from the pleasure of her mouth and finger work.

Her having a good effect on him pleased her greatly, and so she hummed in gentle happiness to communicate this as she continued her fondling. Naturally the humming was twofold in that it was meant to further stimulate his dick too. 'Enough messing around,' she mentally communicated again, 'fuck my face harder. You know you want to....'

And right she was, he wanted to be careful, but she was asking for it, literally. Rapidly he facefucked her, his cock thrusting in and out, hitting the back of her throat.

She moaned into his cock now as it hit her throat over and over, her jugs swaying a bit from the violent jerking back and fourth Mongol's thrusting made her body do, though she didn;t mind. This was more like it, this was how she liked it! Like the slutty girl she was, she began rubbing her pussy to stimulate herself as well, desiring some relief from the increasingly flared female sex.

He saw her try to pleasure herself, but he was too engrossed in his pleasure to say something. He groaned again. "D-don't let me c-cum."

She moaned at her own fingerwork, and in denial at what he said; 'B-But why...?' she mentally whined. 'I-I want your cum...mmmm....!'

"Would you like more in your mouth or womb?" He asked.

She hesitated at this; one or the other? Then again, she mentally slapped herself- of COURSE she wanted more in her womb, she wanted to get pregnant after all. She gradually stopped sucking and pulled her mouth away, panting heavily. She saw no need to give her answer; it was obvious.

Nodding, he understood her want. He pulled back, cock dripping preseed and her saliva. Walking around behind her.

She propped her torso up using her arms, but remained on her knees, raising her ass and pussy into the air for plain view and gently waving it a bit; her tail went straight up. "Do me hard..." she begged. "I want this to be...special..."

His hand went onto her back, "Don't worry, I'll make it special." His tip prodded her entrance.

Her eyes closed and her breath came out in pants as he prodded her; she could feel the liquid in her womb, her inflated belly, weighing her down a bit. Her tits, having been emptied of much milk, were somewhat smaller now, but she could still feel them too. She could feel so many things, and she couldn't wait to feel his dick. "Do it."

At her request, he pushed in, not forcefully, but gently penetrated her, her tight passage enveloping his hot shaft. Moaning as he buried himself in her virgin like tightness.

She let out a light gasp, then a moan as she was penetrated, her inner walls somewhat lubricated by the liquid that had flowed through it before; "Y-Yes..." she murmured lustfully, "Y...Yes...! D-Do me hard...give m-me your children....!!"

Smiling at her tightness and her words, he nodded. "Yes, I will, my love." Grabbing onto her hips, he proceed to rail her as hard as he could.

"GGH! AAH!" Alexei screamed out as she was pistoned into, her entire body slamming forward with the force of it; her engorged stomach helped her to settled down, as her knees gave out in no time at all, she was already undergoing so much pleasured feeling. She was trying to find words to say but was having a hard time forming anything coherent over her own moans.

Slowly he began slamming into her, her ass and breasts bouncing and juggling under his treatment.

Her moans became deeper as drool began to slide from her lips, her pussy walls clenching gently down on his shaft as it went in and out of her at a slow but lovely pace. She could feel her ass and tits jiggling and a momentary giggle escaped her; "Faster..." she purred.

He enjoyed this as much as her. Her walls were so, it gave him so much pleasure. Inside her, his sensitive cock could feel the liquid inside her flowing around his head a it poked her cervix.

She moaned louder as he poked her cervix; "Go in..." she gasped; "Deeper...deeper, break me open...!" Her entire body was shaking in want; she wanted that cock as deep inside as it could get.

"Yes, my dear." Pulling back, his cock almost leaving her as she slowly pulled out, but then he slammed into her a hard as he could, penetrating into her womb.

She screamed out as the deep penetration alone made her cum, femjuice flying out of her pussy as she did; "YES! YES!" she shouted, looking up as she fell forward a bit, resting on her tits with her ass up in the air with him inside; "FUCK ME HARD! HARDER THAN EVER BEFORE!!"

Her enthusiastic request was met with equal enthusiasm from her mate, who proceeded to slam himself into her, his large,heavy sack slapping her. "Oh I will." His cock throbbed deep inside her.

Her screams were continuous and loud, unable to do anything but take it as her body just surrendered, twitching and spasming madly as she was slammed into.She couldn't make any proper sentences anymore, just screamed like the whore she was, saliva coating her chin and the ground in front of her face.

Leaning over her, he let go of her ass, and his hands reached around her, and wrapping around her just below her breasts. While he groaned in pleasure.

She moaned at his touch, her screams dying down as she began to descend into drunken mindlessness; her mind, so fragile when it came to sex, was beginning to tear at the seams with white hot pleasure. The same thought went through her over and over as surely as his dick kept driving into her:

He felt everything she felt, their time engaged in sex, their closeness and previous psychic conversations while fucking. Exhaling in pleasure as his vision blurring from pleasure as he smiled dumbly while fucking her.

Tight pussy...So good...

A similar expression was mirrored on Alexei's own face, a dumb curve to her mouth as she was fucked thoroughly silly by her mate. She was at this point reduced to moaning like a broken record, deep, on repeat, and without any sort of sanity or coherency. Her snatch was going mad around his deep penetrating cock, already so soon after having climaxed once not too long before.

Her moaning may have been drunken, but each moan was a cry for more; a beg for him to fuck to his utmost. A reminder of how much of a slut she was and how she deserved nothing less...

the pleasure she brought him was too much, his sensitive cock going along her tight walls as it sought out her g-spots, throbbing and leaking preseed into her. "I-I'm close..." Her tongue work earlier had edged him, he didn't know how much longer until her blew.

His cock, hitting all her g-spots as well as ramming through her cervix over and over, throbbing wonderfully and making her squirt in warning...it was just too much for poor brainfucked Alexei to take. She couldn;t even respond as her tongue fell sloppily out of her mouth, dropping saliva messily as she let out a happy moan and came again. Her walls clenched down tighter than ever, her cum spattering out and staining her lower legs.

He felt her cum flowing around him, his eyes twitching. He moaned loudly, hilting himself and his sack slapping her ass again, before the floodgates opened. Throbbing madly inside of her, his thick, virile seed spewed forth into her womb with a loud moan.

Alexei gurgled, her floppy tongue hitting the floor as she laid her head down, unable to hold it up anymore as his cum filled her. Her eyes rolled straight up, legs shaking as her womb was flooded; what with the liquid from before already inside, the excessive volume of cum building up inside her expanded her stomach even more, more than it ever had before. So much cum was flooding inside, some of it even splattered out of her, but enough was surging inside her that no matter what, she was almost certainly impregnated.

A deep, deep warmth in her stomach made her woozy and air-headed. Her mind was completely fried, a fucked-silly smile on her face with her tongue still flopped out while her stomach gurgled, continuing to expand.

His head tilted back, and he turned her around on his cock, putting her on her back as he thrust lightly into her, his cock still shooting his load into her. His warm, thick seed filled her and making her stomach further swell as here pulled her into a hug. Laying kisses all along her chest and neck as he continued to cum for another minutes.

Her stomach just kept swelling, able to take plenty it seemed. Every surge of cum flooding inside expanded her further and now she looked way more than just pregnant; yet she was clearly enjoying it. Her pussy continued to spurt out squirts of her own juice on occasion. The hugging and kissing was met by gentle purrs from the out of it Alexei, who otherwise reacted none- her eyes were permanently rolled upwards, her expression perpetually locked in one of utter and glorious bliss. The only other reaction she displayed was an occasional wild and violent twitch or spasm at the cum spewing into her insides; little wonder. This was the hardest she'd been fucked in a long time.

After his orgasm subsided, Mongol sighed contently, his hands wandering along her body. "...thank you..." Whispered Mongol as he feld her, feeling her filled womb pressing against his stomach.

Alexei however was already unconscious; it had been too much for her to take and she'd unconsciously decided passing out was the best course of action. Mongol should have been proud- he was the first to literally fuck Alexei into unconsciousness. All the other times didn't count, as she'd fallen asleep of her own volition rather than out of having been fucked into tiredness. He'd conquered her legendary stamina- all she did now was purr a bit in her rest, occasionally continuing to twitch or spasm, her lolled-out tongue still drooling.

He closed his eyes and slept with her, his cock still buried deep in her womb. Deep inside her, his virile sperm swam the ought her, sought out her eggs and impregnated her. Their experiment had worked, to wonderful results.
