How thw Mighty Had Fallen

Chapter 2: Twist of Fate

After a bit more then two months in this universe, and under the Prime's grip as his lover, bondmate and carrier of his sparkling, Megatron had finally settled down and accepted his fate. He was still bitter and sarcastic, defiant at times, making sure he would never let himself sink into a sickening state of blind obedience. He was still Megatron, the Slag-Maker, Leader of the Decepticons, feared by his enemy and soldiers alike! Or he was when he was still in his own universe. He was sometimes wondering what was happening there since he vanished into thin air. Did Starscream take command? Probably, but did he kept it? Doubtless… Soundwave or Shockwave would have challenged him after a week or two at best. Thinking about it made him feel a bit better… he had not yet been brought into the battlefield, though, and he was starting to get restless without a real battle to fight in a regular basis. He was a fighter; he needed his share of mindless violence and gore.

But there were also the good sides of all this. The kinky interface was one of the best. Just thinking about this made him hot and aroused. They could be very inventive and kinky while interfacing and he had been submitted to some positions and games he would've never thought about before. And right now he wanted to fuck hard. He was almost three months along with sparkling and it made him the horniest mech there is. He was pleasuring himself shamelessly as he was alone in the room he shared with his bondmate, and moaning and groaning quite loudly, leg spreads and digits shoved deep in his port as his other hand was stroking and pumping his throbbing length. "Hooo… Yeah, fuck, YEAH!"

The prime looked over the security monitors in each of the rooms from the throne room of the base. Megatron had finally accepted his place as his mate and soon he would again try to bring up bringing his army there but not until he had his new Battle armour ready. The one he had was good for walking around the base and allowing him access anytime and anywhere, but was not right for battle. Thus the new one was in the works, though he has mildly concerned about the strain it might put on the sparkling. Though he supposed it was theirs and yearned for battle as well.

As he flipped through the channels of the security camera's he came across the delicious display of the gunformer pleasuring himself. His recorder the footage intimidates and removed his codpiece to rub himself as he moved the camera to zoom in on his mate and his intimacy. The purple mech let out a grown of his own and stopped the recording as he opened the comm to there room, "Megatron, Come to the Throne room, your presence is required." He ordered curtly not betraying his arousal, before cutting the communication. He rewinded the footage and replayed it to watch as he waited for his mate to come the volume set very loud as he worked his own spike.

Megatron was caught by surprise by the voice that cut through his pleasured hazed little world. He wasn't that close to overload yet but it was annoying and he growled. But he had to comply, as if he didn't, it would make the Autobot tyrant very angry. And an angry optimus Prime wasn't something funny at all. He didn't bother to put the codpiece of his armour on as he walked out of the room and headed for the Throne Room. He was still running hot and stroke himself shamelessly on his way towards the said room, shooting sensual and arousing looks and half-smile at the Autobots he passed by in the hallways. He received lusting and jealous look in return, the mechs obviously wanting to have a go with him. But he knew, and they knew as well, as he wasn't to be shared with anyone. He belongs to the Prime and the Prime only was to touch him and interface with him. No one else. And if someone tried, he would be facing the wrath of his commander. This thought made him laugh sadistically as he entered the Throne room. He had seen it once, and the poor mech didn't last long. He saw his bondmate in the large chair and stroking himself shamelessly while looking at the footage of him pleasuring himself a few moments before. This renewed his arousal and lust and he stroke himself as he neared the seated mech. "I am here as you commanded, Master."

Optimus purred seeing his mate enter the room, his spike uncovered and looking inviting as he approached. "I need you." He growled and batted the hand off the other's spike and retracting his battle mask. He gave the silver mech's spike a few licks and began to suck him. The prime's finger's diving deep into the gunformer's port to rub the inner walls. He moaned a as he enjoyed the sweet taste of his bondmate's unit. The Autobot Leader's moaning vibrated the spike as his free hand caressed the silver mech's aft.

Megatron could tell that his bondmate was hot and ready to jump him as soon as he saw him. He grinned wickedly and gasped as he was licked and teased, before he was swallowed all and sucked on so wonderfully. And he spread his legs to allow a better access to his dripping port. The combination of the sucking on his spike and the working on the inside of his port made him the hottest he had been in days, and he moaned and cried out blissfully, deep in lust. He grabbed the back of his lover's helm and held it tight against his chassis, arching back. He was starting to feel weak on the knees and trembled slightly as his overload came closer and closer. Pregnancy had this way to make him horny every minute of every day, and he loved it a lot. Fortunately, he wasn't showing yet, and his form was still as handsome as ever.

His mate tasted so wonderful he could hardly wait for him to reach overload. When Megatron spread his legs widered, He plundged his fingers in deeper, the prime could feel the dripping wetness of the port as the mech's fluids coated his fingers. He wasn't concerned about his mate's need for pleasure; in fact it delighted him to be able to return after battle to feel his little gunformer mate from the inside. It was a wonderful way to celebrate victory, or relieve anger from a defeat. The fact that his bonded was still gorgeous only enticed Optimus, but a part of him was looking forward to the sparkling's formation within his mate. He had made sure to check up on the little thing occasionally.

Megatron had had a complete physical exam for the sparkling this morning, and he had been very surprised and somewhat confused to know that he was with twins. The spark had twinned in the last few weeks and he was going to bear two sparklings. He didn't know if he liked the idea just yet, but he'll have time to adjust to the news. He hadn't had the chance to tell his mate yet and he was way too lost in pleasure right now to even care about it. He had to lean on him to prevent toppling over as his knees finally gave out under him and almost sent him on his back. That mouth was the most extraordinary thing he ever felt! His Prime was very skilled with his glossa and lips, and able to send him to the highest peaks of pleasure with only those. And the digits shoved in his dripping port and working his insides were only driving him faster towards overload, his port clenching tightly and spike throbbing and swelling with the incoming explosion. When he finally overloaded, it was hard, and he cried out his lover's name at the top of his vocaliser.

The prime sucked even harder, determined to swallow every last drop of his bondmates overload. When his mate's overload finally passed he removed his finger as well as his mouth from the other's spike and pulled him onto his lap. The silver mech's port would not remain vacant for long as Optimus pulled him onto his still throbbing spike. He did not thrust at first. "So, did you have the check up on our Sparkling?" he asked giving his mate a deep and hard thrust, then waited for the answer. This was a new little game for them and he'd always wanted to 'face Megatron on his throne.

The first overload let Megatron a bit drained and he gasped slightly as, after being pulled on his lover's lap, he was penetrated deeply. The feeling of being filled to the brim had become a common occurrence for him those last few months and he had grown to love it a lot. He ever got at least two overloads every time they were interfacing, as he was as insatiable as his Bondmate. Together they made a pair of savage and feral mechs while it came to interfacing. The deep, hard thrust he was given made him arch and cry out a bit, moaning in lust, and he knew that if he wanted more, he'll have to answer the questions that were asked. "Yes, I did, and I have news. We are going to have twins! The spark twinned in the last two weeks and separated in two…" He keened and writhed, waiting for more of the hot and throbbing length to impale his aching port. His arousal had returned to its full high and his spike had risen again to its full length, throbbing with need.

Twins?! He'd have to make new arrangements for two new warriors for his empire. "Twins you say? You do excellent work my mate." Optimus stated nuzzling the silver mech's neck cables and delivering four hard good and deep thrusts as a reward. Each thrust making the Decepticon bounce on his lap, but it soon stopped again to resume the game. "And you didn't think you could be a mother." He chuckled, playing with the aroused spike a little. "Do you think you can do battle with the twins in you?" he asked giving one thrust as before. The prime wanted to be sure Megatron could handle fighting in his current state before revealing his new gift to him.

Megatron arched and moaned in lustful delight when he was thrusted into so wonderfully. His mate's spike was big and goes so deep it can hit the very end of his interfacing port, sending jolts of energy and pleasure through his entire system. "T-thanks…" he managed to stammer out as he was pounded so nicely. He spread his leg even more to give his mate full access and a better angle to thrust. "I'm still not sure about the mother part…I'm not a kind and loving mech!" And to make his words get through he slammed his hips down hard, groaning and gasping at the pleasure he got from this. But as for the last question, the answer was clear to him. "Yes, I am confident than I can battle with being with the twins inside of me. I fought with worst injuries than you can imagine. That is nothing." He was being honest, he really think he could battle while carrying twins. He was strong and powerful, as much as his mate probably, and battle-hardened. He leaned on his mate's front and turned his head to kiss him roughly, daring to make a dominant move.

Optimus gave the tip of his mate's spike a pinch. "All the better as our sparklings will be strong warriors." He replied with a groan as the silver mech slammed down on his spike, the pleasure was welcomed and he played a bit more with his lover's unit. He nibbled at the gunformer's neck cables for a moment as Megatron informed him of his battle status. The prime allowed his bonded to have the upper hand, at least for now. Kissing the Decepticon leader and thrusting into him deep and hard a few times to pleasure the other as he moaned into the struggle for dominance. When the kiss ended he couldn't resist the urge to tease his mate, "When you kiss me like that, your "I hate you" statements are less believable." He pointed out. The Autobot Leader gave his lover a few more good thrusts. "But since you've been good, I have a treat for you." He stated opening up his access port and allowing his mate to be on top for once; though he wondered if the silver mech would take it.

Megatron writhed and gasped as the tip of his hard and throbbing spike was pinched and the length was stroke and played with, and he slammed his hips down again in answer of the deep, pleasurable thrusts he was getting from his mate. He was smirking into the kiss; having the upper hand for once was great and he enjoyed it greatly, fiercely kissing back his lover. "I still hate you…" he whispered huskily with a little playful chuckle at this statement, and added. "But I love hating you…And It is a good kind of hatred." He was being silly and he knew it but he had every right to be. He was a plaything and a little pleasure bot in this universe, and longed for the battle lust and energon spilling of the Pits sometimes, or the way he had ruled his Decepticons with an Iron grip, slipping fear in their spark, afraid of his mere presence. "I crave you is more accurate of how I feel…" he was surprised when he heard the click of a access port opening and stared at his bondmate for a long moment. Then he had a devilish smile and turned around, straddling his legs. "You want me to take you? I will oblige with a great pleasure, my Optimus…"

The prime revved his engines in response returning the passionate kisses. He more then craved this Megatron however, from his attractive form to his strength and Personality. Taking him into battle to fight the Megatron of his world was going to be thrilling! He couldn't wait to see the expression on his nemesis face plate. Optimus grinned back at the gunformer and parted his legs so that his mate would have full access to his port. "You Crave it don't you? Go on My handsome Megatron, Take me... If you think you can handle it that is." He purred out teasingly.

Megatron kissed and nibbled at his mate's neck, so hard that it was painful. The mere idea of taking him for once was driving him wild. He growled and his optics shone a brighter shade of red as he lowered himself into his mate and positioned his spike at his entrance, brushing slightly at the sensitive plating, pushing only barely inside for now. "I can handle it alright, my delicious mate…Hmmm…" He purred and kissed him again roughly as he finally entered him, pushing all the way and giving hard and deep thrusts. He enjoyed the heat and tightness of his lover and gasped at the pleasure he got from this. He was by no means small nor was he gentle. His way of interfacing was rough and hard, and he was taking his sweet time to enjoy it fully.

Optimus growled in arousal at the painful bite as it excited him all the more. He felt the Decepticon leader's spike tip teases his entrance so wonderfully, making his port drip. Optimus moaned into that kiss and arched his back as he was entered. He moved his hips to meet each thrust, it was his first time being entered and he reasoned that if it was ever to happen he wanted to be sure it was his mate that took him. The Prime was enjoying it though he liked it hard and rough and his mate was big and felt so good that he moaned his pleasure, "Deeper!" He called out in the throes of pleasure.

Megatron was turned on by the sight of his bondmate writhing under him and he moaned loudly as he thrusted harder and deeper into his tight, dripping port. His opening was slick and so well-lubricated he could slide in and out without problems. "My Optimus…You didn't tell me you were untouched down there…" he smirked widely, devilishly, and gave the deepest, hardest thrust ever since they began. He whispered in his audio, sensually. "All the better for me, I guess… I love virgin ports; they are the best to take…" He loved to talk dirty, and this was very mild and teasing at the same time. And he reached with a hand to tease the other's spike and play with his arousal as he continues his thrusts.

The thrust made him whimper in sweet bliss as it was the deepest the other had gone into him and it was wonderfully rough. Optimus growled in response loving every moment of the dirty talk. Is port was thoroughly coated and moaned and let out delightful little whimpers with each thrust his mate delivered. The prime continued to meet the others thrusts, the easing of his spike were rewarded with a few spurts of mech fluids from the tip of his unit. "I figure if I give anyone my port, it'll be you." He replied to his bonded as he moaned and enjoyed his mate's spike. He never thought he'd enjoy being taken like he was at that moment, as he felt his overload building.

That declaration made Megatron's optics widened for a second and he was taken by surprise. He didn't expect this, not at all… It was a proof of love and trust, wasn't it? To give someone your virginity… So this dark Prime was capable of loving and he was being honest when he told him that he loves him. This thought mead him moan and increase his thrusts with renewed enthusiasm, going deeper and harder, trying to find his lover's sweet spot to pleasure him even more, changing his angle of penetration a few times to do so. "So you really love me… I didn't believe this until now, my Optimus…" he purred in his audio and kissed said audio sensually. His stroke and teased the hard spike a bit slower, he didn't wanted this blissful moment to end too soon, even if he was feeling his own overload building up quite quickly. It was the best interface he had since he got in this reality. And in the ends, he thought while pounding in his bondmate's slick port, he was thinking that his situation wasn't as bad as he first pictured it… He was eager to show his bonded how good he could be in battle, now, and trash some poor mech to pieces.

Optimus leer up at the gunformer as he saw the surprise on his face plate. "I told you I loved you, My Mighty Megatron." He purred those words, if he was going love anyone it would have to be a warrior as terrifying and powerful as him, and when he bonded with this Megatron, he saw such a warrior. The black and purple mech moaned sweetly his pitch heightened when his lover hit his sweet spot. Soon the Autobot leader was whimpering and calling out for the silver mech, his audios burned at the purr and the kiss only made it sweeter. The primes optic's burned with desire as his bondmate teased his member slower now, but it felt so good. Each thrust he answered by bringing his hips to meet the other, sweetening there interfacing by sending his feelings of lust and even love for his bonded through they're link. He felt his Overload hit just then despite his desire to have hit last a bit longer. The surge of energy assaulted his systems and he cried out in wonderful pleasure, his spike spraying them both with his fluids. "Do you love me now, my beautiful and deadly Megatron?" He asked as his systems cooled, red optics locking on red optics.

"And now, I believe you, my wonderful, terrible Bondmate…" Megatron purred back in his audio and thrusted several times, hitting the sweet spot he just found every time he pushed deeply in his tightened and hot port. He felt so good; Megatron had rarely been so aroused while taking another mech. Those whimpers and the way Optimus was calling his name out only made him go harder, deeper and aroused him like he was on fire. "Yes… Call my name… I love it when you call my name like that…" he sent back his own feelings to him, deepening the connection between them and there was lust and need, a lot of it, and a blossoming, still uncertain love. This was a bit unsettling but he relished on this, absorbing the feeling like it was nectar and purring loudly in harsh, rough joy. When the Prime's overload hit, he got the feedback and arched back, crying out his lover's name along with him, in bliss, releasing deep in his port as he reached his overload at the same time as him. After it was done, he teasingly brought his coated hand to his mouth and licked off the lubricant sensually, purring. "You taste wonderful, my Optimus…" His optics then locked with his lover's and they were burning with a deep, inner fire. That question was a little tricky but… he analysed his feelings for a bit and then he answered as honestly as he could. "Yes… Yes, I think I love you now, my Bondmate. Even if reluctantly, I love you."

Optimus pulled his silver treasure close to him and kissed him deeply. "Then come let me show you what I've been making for you." He purred stroking his mate's helm tenderly as he got up from his throne, still holding the Decepticon leader in his arms. The black and purple mech re-attached his Codpiece and beckoned for his mate to follow as he descended down the hall from his throne and headed to the weapons and armour manufacturing sector of his base. The room had been seal from Megatron before for obvious reasons, but now the Prime had no worries about his bondmate trying to slag him. In the room the walls were lined with weapons and armour of all types for various mechs. All custom designed by the dark prime himself, but one stood out that was clearly meant for his bonded. The silver and black armour was strong, powerful and durable. It allowed for quick reflexes and favorability. The chest had added armour to protect the spark chamber, no doubt the prime had been thinking of their sparklings well being when designing it. "With this, you will join me in battle." He stated, and even though the armour showed off his attractive frame, it did not reveal anything like the first three armors the Prime had given his mate.

Megatron smiled back at his mate as tenderly as he could manage and kissed him back as deeply; leaning on the feelings he was still receiving from him in the afterglow of the interface. He nodded when he told him to follow him and nuzzled his neck a last time before he was put down in his pedes. He looked down at himself, blushing slightly, because he hadn't brought his codpiece with when he came to the throne room, and was still bared in the intimate areas. But he shrugged it off and followed his bondmate. He was led to a part of the base that had been locked to him since he arrived for obvious reasons, as it was the part where armours and weapons were manufactured and designed. But he had no intentions of killing his bonded anymore and only looked at the numerous and deadly looking weapons shown in the walls with the awe of a kid in a sweet factory. "Wow, I'm impressed. That is an impressive collection. I would like to try some of those weapons." Then he was led to a particular room and shown one armour that was obviously designed for him and him alone. It had thicker plating on the chest and abdomen for the sparklings, and was looking dangerous and deadly. Just like him… He reached to touch the black and silver craftsmanship and smiled in appreciation, nodding with a little whistle. "I will follow you gladly while wearing this magnificent piece of art, my beloved bondmate. It is a very good work."

Watching his awed mate, Optimus chuckled a little at his comment. "And so you shall My Megatron, This room is now open to you when ever you want into it." He purred kissing the silver mech again enjoying the fact that at last he was getting what he wanted from his bonded. His arms wrapped around the Decepticon Leader as they now gazed at the armor. "I made this especially for you; after all, it might get a little cold to have your port open on the battlefield." The prime stated as his fingers caressed the gunformer's aft affectionately. "But keep in mind that on the battlefield you will fight those that appear to be your own men... including yourself." He cautioned. Pressing a few keys, the armor lowered and the Autobot Leader gestured for the silver mech to try it on. "If it fits well, we can head out to battle as soon as you're ready." He growled hotly as he watched his bonded intently.

Megatron kissed him back and leaned on his bonded when he wrapped his arms around him tightly, stroking his bared aft. "I can't wait for this… the heat of battle always makes me so hot…" He purred in his audio and smiled sensually. He was awed of how fast he had turned over in this relation, going from pet to bondmate in a matter of hours, literally. Because he had accepted the fact that he was loved and could love back without restriction. What he would never had gotten from his Prime, or Starscream. "Yeah, I wouldn't want to catch a virus while I'm carrying our sparklings, wouldn't I?" He laughed at the comment about the bared port. Then his smile faded and he took in a serious and thoughtful expression. "Yes, I understand this. Those Decepticons are like the Autobots of my Universe, aren't they? I can hardly imagine myself all mushy and goody-good like My Prime. I would be an interesting encounter that is for sure…" He looked at the armour as it was lowered and then shot his mate a little smirk and started to get his armour off slowly, deliberately teasing. "I can't wait. I need some good old-fashioned massacre and gore once in a while." The armour was fitting just fine, and it was loose in the abdomen area so it could stretch to accommodate the twins when they grow.

"You'll be seeing it a lot my mate." Optimus purred looking forward to the moment when he could see the gunformer in battle. "Though... I could always
keep your port covered in a different way, but that might make battle difficult." He stated seductively until Megatron became more serious. "Indeed, but we can
Also use this to our advantage. The confusion you'll be able to cause will give us an edge. I plan to use that my mate." He stated as he watch his mate remove his
armour. It was slow, teasing and he couldn't help but rub his fingers along the silver mech's body and play with the others spike a little before allowing him to put the
new armour on. Tilting the Decepticon leader's head up, the prime kissed him deeply before taking his hand in his own. "Shall we then, my beloved?" The Autobot leader
asked, ready to lead them out to battle.

The little teasing made him shudder and smile seductively at his mate, showing off his perfect body a little more then it was needed only to change his armour. He managed to keep a strong hand on his feelings and didn't let his arousal took control of him, even if the teased spike stirred a bit. But then he put the crotch and hips plating's on and it was hidden again. "I bet. Those Decepticons won't see this coming! And I think it may even be a lot of fun for me, my mate. And that Megatron, he intrigues me… I can't wait to see him face to face!" he smirked with a predatory smile, rubbing his chin in expectation as he thought of the incoming battle, and the encounter. When he was sweepted into that heated kiss, Megatron returned it with a ferocity and hunger very obvious. He teased his mate's lips and glossa a little before pulling out. "Yes, I am ready to go into battle, my beloved. Our enemies won't know what hit them!" And his expression was one of blissful battle lust and it was almost a sexual kind of expression.
