Orion had been acting…skittish.
He seemed to be acting off the whole day.
Orion didn’t talk much in the mines, he was actually well behaved, and, most strangely of all, he kept avoiding D-16. Anytime their optics met, Orion would quickly turn his helm the other way. It was frustrating D-16. Why was his best friend ignoring him?
D-16 walked through the streets of Iacon. He figured a walk would help him feel better…a lonely walk. D-16 sighed at the thought. He didn’t like being alone and with Orion avoiding him, he felt like he had no one.
Dusk slowly fell over the city. Various types of shops lined the street. The buzz of bots getting out of work was beginning to die down. Everyone was either running errands or going home. D-16 was kicking a round rock along the sidewalk as he roamed about.
D-16 looked up and spotted a familiar red and blue paint job. Orion was running down the sidewalk, frantically checking each of the stores’ windows. He must be looking for something important.
D-16 thought this was the perfect time to confront him. Maybe once they talked, he could help Orion look for whatever he’s looking for. D-16 steeled himself and marched towards Orion.
Orion hadn’t noticed D-16 was behind him. He was carefully looking through the store’s supplies through the window. D-16 cleared his intake, making Orion jump.
“Hey, Pax…uh…I was—“
Orion quickly fled the scene. He didn’t make it far before D-16 grabbed his wrist.
“Pax?! Hey, what’s wrong? Why are you avoiding me?” D-16 questioned. Orion’s metal plating was hot under his servo. Too hot. D-16 tried not to let go. He was determined to get to the bottom of this and fix whatever he had done to make Orion ignore him.
“Dee— just-just let me go, alright?” Orion tried to pull himself away from D-16’s grip, but it was too strong.
“At least tell me what I did so I can fix it!” D-16 said firmly.
“You didn’t do anything,” Orion swallowed, “I need-I need you to let me go!”
D-16 didn’t want to let go, but Orion’s plating was burning the sensors of his servo. He released his grip, cradling his servo as he saw Orion dash into an alleyway. D-16 quickly made his way over.
The sky was beginning to darken. Colorful hologram signs were beginning to turn on, their lights illuminating the street. D-16 peeked into the alleyway. It was dark, but he saw the blue shine of Orion’s optics. He was sitting down further into the alley, his chassis heaving as he gasped.
D-16 slowly walked to Orion. He choked when he saw Orion’s valve panel was removed and his digits were plunging deep inside himself. The sound of his cooling fans on full blast filled D-16’s audials.
“Pax what are you doing?! Here?!” D-16 stumbled back. He needed to look away, he must look away, but his optics were glued to Orion’s pretty valve.
“Oh Dee…I ate something I shouldn’t have. An appo-um…aphro-uhh…oh whatever! And now…now your touch amplified this feeling I’ve had all day,” Orion whined, his digits not stopping. He rested his helm back against the wall with his back arched. Drool trailed down his chin and coolant gathered in the corner of his optics.
D-16 was frozen. Not only by the lewd sight, but also from Orion’s words. Of course he ate an aphrodisiac! It’s not surprising Orion made another stupid decision.
“Is this why you’ve been ignoring me all day?” D-16 asked slowly. He could feel his spike panel getting tight. Orion nodded.
“Just looking at you made the heat worse and…I didn’t want to do something I’d regret,” Orion gasped, his digits hit his interior node.
“Something you’d…regret?” D-16 was drawn to the wet squelches from Orion’s valve.
“I value our friendship and I didnt—ngh—I’m afraid I’ll force you to help me! I don’t want that!” Orion was panting with his optic ridges knit in concentration. His digits started to slow down.
“Y-You could’ve told me! We could’ve figured something out earlier!” D-16 reasoned with his servos gesturing wildly.
Suddenly, Orion leaned forward and started to slowly crawl towards D-16. D-16 backed up until his back hit the wall behind him. Orion’s servos latched onto his pedes as if they were magnetized.
“Leave! before I—mmng,” Orion couldn’t finish his sentence and started licking long stripes along the side of D-16’s leg, just below his knee. D-16 could feel the heat radiating from Orion’s frame.
This must be a dream. Another filthy dream D-16’s processor cooked up because this was too good to be true. D-16 had always wondered, daydreamed really, how Orion would look like this: desperate and needy. No way this was real.
Orion’s glossa trailed up to D-16’s inner thigh, his servos pawing at D-16’s interface panels. Okay…maybe this wasn’t a dream.
“Deeee,” Orion pleaded, “Dee, I need youuuu…please help me.” Orion rubbed his helm on D-16’s thigh. The coolness of his best friend’s frame was the only relief Orion had felt since the day started. Short hot pants escaped from his mouth and fogged D-16’s silver metal plates.
D-16 let out a shaky exvent and tore his gaze away. He started to weigh his options like a reasonable mech would. He could help Orion and make the effects of the aphrodisiac go away right here right now or…they could wait it out. Although, waiting it out posed some great risks to Orion. The aphrodisiac has already lasted the whole day; it might be one that only goes away with an assisted overload. If that’s the case and they wait too long, Orion’s internals could melt!
D-16 reached to his codpiece and popped off his spike panel, finalizing his decision. His spike immediately pressurized and bobbed in air. Orion moaned at the sight of the black colored spike with orange bio lights. He excitedly thought of the girth stretching him soon. He quickly wrapped a servo around it, unable to close his fist from the width, and wasted no time in sliding it into his mouth.
D-16 shivered at how warm Orion’s mouth was. His servo hovered over Orion’s helm, his frame still too hot to the touch. Orion quickly began moving up and down D-16’s length. D-16 bit his servo to stifle his moans while Orion didn’t care if anyone heard him.
Orion could feel every ridge of the spike slide smoothly into his mouth. The head of D-16’s spike reached well past his intake. Orion gagged but he didn’t want to remove himself.
D-16 stiffened and slammed a fist against the wall behind him. His optics were screwed shut. His charge was climbing too fast.
“P-Pax…mnph…Pax!!” D-16 yelled and managed to grab Orion’s helm and push him all the way down. His spike twitched with every shot of transfluid into the other’s mouth. Orion keened at the feeling of the warm oily fluid going down his intake.
Orion kept sucking D-16’s spike, not even pausing for a breather. D-16 began to feel a burning sensation from the overstimulation. He reached down and pulled Orion’s helm off his spike. He didn’t release his hold on the blue helm and instead angled it up to make contact with Orion’s dimmed optics.
“Th-That’s enough! I’m supposed to make you overload!” D-16 managed to get out between fits of static. Orion’s mouth was open and his glossa was sticking out as he gasped for air. He had a dazed expression on his face. D-16 doubt Orion heard him.
“Here…stand against the wall,” D-16 said as he picked Orion up. He gently laid him against the wall. Thankfully, Orion could still stand on his own. D-16 looked down and saw pink smears all over Orion’s thighs. The mesh of his valve was swollen and his bright blue node was blinking irregularly.
D-16 caged Orion with one arm and raised one of his legs with the other. He grabbed his spike and rubbed it on the grey folds, making more of a mess with Orion’s lubricants. The contact made Orion tremble.
“I-In…Inside!” Orion stuttered, his hips bucking against D-16’s. D-16 held Orion’s impatient hips with his strong servos.
D-16 sucked in a vent and held it, bracing himself. He positioned his spike and easily slipped faster than he intended into Orion’s hot valve. Their arrays were pressed firmly together when D-16 bottomed out.
Both mechs groaned loudly. Orion from finally being filled up and D-16 from the tight heat of the valve. The feeling of his calipers struggling to circle around the girth of the spike made Orion whimper.
Orion clutched onto D-16’s shoulders. His servos were still searing hot, but that was the last thing on D-16’s mind.
D-16 muttered a small prayer of gratitude to Primus under his breath. He began to slowly move his hips back. Orion was so wet, there was almost no friction. It took everything in D-16 not to start slamming back into Orion’s sopping valve.
Lubricant dripped onto the ground as D-16 carefully slid back in. He bit back a moan when he bumped Orion’s gestation seal.
“D-Dee…” Orion’s soft voice snapped D-16’s attention towards him. “If you don’t start pounding me into this wall right now, I’m afraid I’ll melt and die,” Orion whispered, his hold on D-16’s shoulders getting tighter. He felt so much pleasure from D-16 thrusting slowly that he couldn’t keep his optics on the silver mech, but he needed more.
“R-Right…yeah…” D-16 nodded as he pulled out slowly until only the head of his spike was inside. He took a couple deep vents and, without warning, shoved himself inside in one quick motion. Orion gasped and his optics widened. D-16 set a brutal pace, which was exactly what Orion was craving.
All of Orion’s internal nodes fired through his sensor net at once, making him arch off the wall. He moaned and whined and kicked. Tears streamed down his cheeks from the intense pleasure of D-16’s roughness.
Orion left scratches on D-16’s plating, making him groan. The sound of their hips colliding bounced off the walls of the alleyway. Orion quickly shoved his lubricant filled digits into D-16’s mouth. D-16 moaned at the sweet taste and sucked the best he could while keeping his rhythm.
Warnings flashed in Orion’s HUD about the temperature in his frame rising to a fatal degree. Light steam started to expel from the gaps in between his metal plates. The energon in his fuel lines was starting to evaporate.
Orion tried to tell D-16, but the only sounds that came from his voicebox were static-filled moans. He tried to focus on his pleasure, trying to make his charge climb faster.
The way Orion stiffened suddenly and squeezed his optics shut alerted D-16 that something was wrong. His hips started to slow down. Orion frantically shook his head
“Mm-!” Orion tried to speak, “d…!” He wanted to say ‘more!’ or ‘don’t stop!’ but neither came out. Luckily, D-16 got the message. He grabbed Orion’s waist and pulled him harshly in time with his thrusts.
D-16 inched his servo closer to Orion’s flickering node. He pressed on the little nub and moved it in a circle. Orion’s noises got louder. He took his servo from D-16’s mouth and clamped it onto his own. Which didn’t do much; Orion was practically sobbing.
Two more bruising thrusts and Orion’s callipers squeezed around D-16’s spike in a fierce overload. White sparks danced across his vision. His firm grip left dents on D-16. A long groan left D-16 as he overloaded inside Orion. The rhythmic flutters of the calipers milked his spike for every drop.
They both stood there, panting and covered in condensation. Orion’s HUD notified him that his frame’s temperature was going back to normal. He felt utterly exhausted and sore. He limply fell onto D-16’s chest.
“Woah, you okay?” D-16 asked in a worried tone, steadily holding Orion up. Orion could only nod in acknowledgment, his voicebox fried. His legs felt wobbly and his helm felt heavy. D-16 slowly sat him down on the ground. He placed his servo on his forehelm.
“You’re not burning up anymore…the aphrodisiac must be out of your system now,” D-16 said with a relieved sigh. Then he clicked his glossa. He wanted to scold Orion for being so much of an idiot that he consumed an aphrodisiac in the first place. Primus below, he could’ve died! But seeing the tiredness in Orion’s face made his anger subside.
“Come on…let’s go back to the barracks. You need to rest,” D-16 whispered. Orion deliriously smiled at him. D-16 swung one of Orion’s arms over his shoulder, grabbed his waist, and hauled him up to his pedes. Orion chuckled to himself at how he couldn’t stand on his own.
Orion snuggled up against D-16’s frame. D-16 rolled his optics with a soft smile in response.
Soundwave and Shockwave will never stop having kids. Soundwave loves being pregnant and being bred. He also has so much love inside him he loves his kids so much. Shockwave is very happy to contribute that mech loves to breed his mate. I Headcanon him to have been an Insecticon so those instincts to breed and create more soldiers never went away.
Seeing Sentinel hunched over a desk was a completely new sight for Optimus. Sentinel never studied for anything. He rests a servo on the blue bot’s shoulder plating, looking over it to see what in the pits he was so concentrated on.
“Optimus? What are you-” he’s interrupted by a yawn, “what are you doing awake?”
“Sentinel, the test is two solar cycles from now. Are you really that concerned about studying?”
“I uh, wasn’t paying attention to the lessons.” of course he wasn’t. “You should go recharge.”
“We are gonna go recharge.”
“Optimus…” he whines, not making any effort to stop the red bot from turning the chair around and lifting him. Optimus half throws him over his shoulder, holding his aft to keep the blue bot steady. Sentinel blushes and sighs, letting the red bot lay him on his own berth.
“Stay.” he whines again, but Optimus cuts him off. “You’re gonna stay here and get some recharge.” Sentinel reaches for him with grabby-hands, Optimus laughs. “You want me to join you?” Sentinel nods enthusiastically, smiling as the other bot lays close next to him. He turns on his side to face his partner, kissing his face and hugging onto him.
“You know,” Sentinel starts, “if you really wanted me to recharge you could, I dunno, tire me out?” he smiles hopefully.
“I think you’re already tired, Sentinel.” Optimus kisses the side of his faceplates, rubbing the blue bot’s side.
“You’re no fun.” he pouts, mock frowning and looking away from Optimus. Sentinel turns back towards him after a klik.
“I’m not supposed to be fun, sweetspark.” Optimus says softly, kissing his faceplates again.
“C’mon,” Sentinel whines, “Not even one round…?”
The red bot giggles, considering the possibility and deciding to make an offer. “Only if you top.” Sentinel sighs obnoxiously at his response, begrudgingly climbing on top of Optimus.
“I hate you…” he whines again, half laying on Optimus and kissing his neck cables. The red bot chuckles, putting his servos on Sentinel’s waist and popping his panels open. His half pressurized spike rubs against the blue bot’s valve panel.
“Love you too.” he sighs, rubbing Sentinel’s sides. The blue bot smiles, gently talking Optimus’ spike in his servo, letting his plating slip back. Sentinel hovers over his spike, he looks tired. “Sweetspark…?”
“Huh?” he blushes, his attention snapping back to Optimus. He blinks with an “oh,” before going back to what he was doing, he rubs the red bot’s spike against his exterior node, making him gasp.
“Too tired?”
“No, I could go for-” Sentinel grunts with effort, bouncing on his partner’s spike, “go for cycles…” Optimus smiles, sitting up to kiss the blue bot’s collar guard and chassis.
“I don’t believe you.” Sentinel groans at the response, dropping and grinding down onto the red bot’s spike and squeezing on him from the feeling. His movements start to become jagged, he shakes as his frame turns more and more unwilling to move. Optimus has an amused look on his faceplates. “Tired yet?”
“No,” Sentinel whines, putting a servo on his lover’s chassis and pushing him back down onto the berth, “I… I wanna-”
“Hey,” he cups Sentinel’s face, making him look down at Optimus, “You don’t need to. So get back down here. And recharge with me.”
The blue bot looks adverse to the idea, slowly giving into it and lowering himself to lay chassis to chassis with Optimus. He sighs, wraps his arms around the other bot’s waist and puts his faceplates against Optimus’ neck cables.
“Sentinel…?” the red bot puts a servo on his back strut, gently rubbing him.
“Mmph.” Sentinel huffs, rocking his hips shakily on top of the other bot, giving up after a klik. Optimus coos, petting his spinal strut and kissing the top of his shoulder. He sighs, wishing that Sentinel would get off of his spike before falling into recharge, but his light snoring is enough to make him alright with it.
can't stop thinking about optimus easing a very pregnant starscream out of recharge by eating him out.
it's one of his favorite things, honestly. he's got one servo rubbing starscream's belly, the other gently massaging his aching hip, all the while he's lazily slurping up starscream's transfluid, sucking on his node just to watch him squirm in his sleep. optimus is trying his best to not wake him - starscream needs all the sleep he can get with bitties growing inside of him - but he can't help himself as his engine idles, purring away from how much he's enjoying starscream's soft, sleepy little whimpers.
it takes everything in him to not rut against the berth and make himself overload too quickly as he watches starscream wake up, his cooling fans whirring to life, faceplate blushing blue as he looks past his belly and sees optimus drinking him down like his body's producing the finest energon in the galaxy.
starop fragging where optimus is curled over starscream's entire body, so big that you can't even see starscream's body beneath optimus' massive frame except for his fluttering wingtips poking out. that's it, that's the post.
