Knock Out tries something new with his beloved Conjunx.

After a long day of working their afts all day in the med-bay, Breakdown and Knock Out finally settled down in their habsuite and got their well needed rest, but the medic had other ideas. As the bigger mech laid on his back beside him, Knock Out nudged him to catch his attention, waking up Breakdown in the process.

"Say, sweetspark, how about we try something new tonight?" Knock Out asked, smirking at his Conjunx, there was a twinge of sultriness in his velvety voice.

"Of course, darlin'. I'm always up for somethin' new!" The blue bruiser exclaimed, the thought of trying something new with the mech he truly loved never ceases to get him all giddy. He's always open to experiment with his Conjunx, medical or otherwise.

Knock Out crawled on top of the larger mech and straddled him, bringing his faceplate closer to his and enveloping him in a passionate kiss. Breakdown opened his intake, inviting his Conjunx's glossa in. The medic pushed his helm further, deepening the kiss as their glossas wriggled for dominance and lubricant pooled to their chins. Both of their servos ran along their frames and grinded against one another as their kiss becomes more lustful. Grunts and moans slipped out from their intakes as they enjoyed each other.

Knock Out eventually pulled away from the other's lips, leaving a trail of saliva behind as it separated.

"Can ya open up for me, KO?" Breakdown asked as he brushed a digit on the medic's interface panel, causing him to let out a soft whine.

"You first, big boy." The sultriness in the medic's voice aroused Breakdown, causing him to make quick work of his interface panel. His huge, thick spike quickly pressurized as Knock Out looked in awe at his length. No matter how many times he's seen it, the sheer size of his lover's spike always delighted him to no end.

Knock Out soon followed, his spike wasn't as thick as Breakdown's, but he was pretty well-endowed for a mech his size. He gently rubbed his length against the other's as pre-fluid beaded at their tips, one of his servos joined in shortly after and pumped both of their spikes, adding extra friction. They both let out pleasured moans and grunts as they rutted their spikes against the doctor's hand until both of their overloads combined with one another.

Despite his larger stature, Breakdown already looked drained after overloading in their first session. Knock Out went down and cleaned the both of them up by licking their excess fluids. Seeing his Conjunx lap up the result of their sweet lovemaking aroused him all over again, bringing the bruiser back from exhaustion.

"We still have a loooong way to go, sweetspark." The medic snarled, trailing his servos onto his aft plating, gently rubbing it as Breakdown whimpered and whined at his touch.

"Please, doctor. Let me have this!" Breakdown whined in desperation, expecting the smaller mech to use his valve. He ruts against the other's servo as Knock Out ran his digits along the larger mech's seams.

"Now, sweetspark, I want you to bend over and show me your juicy little port." Breakdown obediently followed his command, rolling over and presenting his aft in no time, revealing his tight pucker to Knock Out as his impressive spike hung between his struts. Knock Out bit his lip at the sight, trying his best to restrain himself from fragging him silly so quickly.

"Be gentle, darlin'. I haven't done anything like this before." As open as he was to trying something new, he always takes precautions beforehand.

Knock Out gave his Conjunx a reassuring look before running his glossa over the hole, tenderly caressing his aft-hole as Breakdown's frame shudders in arousal. He couldn't believe that after vorns of them together, he never considered feeling this kind of pleasure. his spike was throbbing and twitching, desperate for attention as it leaked copious amounts of pre-fluid.

"Primus, I never expected how good you'd taste." The medic was completely lost in bliss, the taste of his own lover on his glossa drove him mad as his own spike twitched and throbbed. Coarse moans and delightful whimpers escaped the larger mech's intake as Knock Out crammed his glossa deeper into the passage, he was growing closer to his overload.

Sensing how close he was getting, Knock Out swiftly pulled away from his pucker. The brute grunted in disappointment as the smaller mech denied him of his release.

"I'll give you something better instead, dear." The smaller mech grabbed a half-empty bottle of lubricant from one of the drawers, Coating his digits and Breakdown's port with a generous amount of the liquid.

He prepares the larger mech's tailpipe by inserting two of his digits inside, making sure that it'd comfortably fit his spike. The foreign sensation of being penetrated from something other than his valve caught him by surprise, but he got used to it fairly quickly. Breakdown let out small groans and moans as Knock Out went to town using his digits before shortly pulling out when he considered it to be loose enough for him.

"Go ahead, darlin'. What are you waitin' for?" Breakdown said eagerly. The smaller mech's spike slapped against the wet pucker before he slowly inserted the head of his length into the tight passage.

"By the Allspark! You're tight as slag, Breakdown." Knock Out moaned as his spike wriggled deeper into the brute's aft-hole.

"I told ya it's my first time doin' this." The larger mech reminded. After they both finally adjusted to the new sensation, the medic slowly started moving, making sure that the other is comfortable. His spike was reaching depths that he never considered exploring.

"Unngh– Knock Out! You feel so fraggin' good…" Breakdown grunted, his engines revved as the smaller mech thrusted harder, squeezing out moans from his Conjunx. His optics twitched as his glossa hung out from his intake.

The medic repeatedly slapped his aft as he went at a rapid pace, the head of his spike continuously hitting the most luscious spots of his hole. The room was nothing more but a menagerie of rough clanking noises and passionate sounds of their lovemaking, it smelt of nothing but sweet, hot motor oil and their excess fluids. Breakdown was completely at Knock Out's mercy, letting the other absolutely demolish his then unused aft-hole.

"Mmmh– Oh, Frag, Breakdown. I'm so close!" Knock Out reached a servo to the other's length and swiftly jerked him as he continued his rough pounding, timing it with his thrusts. Both of their circuits went haywire as they lost themselves in their own pleasure, shaking and trembling as they get closer to their climax.

Finally, after a rough session, they finally came to their releases as thick globs of transfluid spurted from their spikes, staining the sheets with their combined fluids. The then white sheets were now tinted with pink as a result of their passionate love. Knock Out hastily pulled out from his Conjunx's tailpipe before admiring his stuffed, gaping hole. He kissed and licked at the used tailpipe, slurping up his own fluids as he marveled at his own work. The smaller bot eventually pulled off from the pucker, leaving a string of saliva behind as it made a 'schlk!' sound. Knock Out laid Breakdown on his back as he shoved his glossa into the other's intake, giving the bruiser the taste of his efforts before slowly pulling away.

"You cleanin' this up, Doc?" Breakdown teased, already knowing the answer. Knock Out let out a playful sigh as he quickly got to work changing the sheets to brand-new, fresh ones before grabbing some cubes of Energon. Breakdown yawned as he pulled Knock Out close to him, holding him in a warm embrace after they both refreshed their systems. The smaller mech melted into the cuddle, nuzzling his helm onto the other's chestplate.

"I love you more than ever, dear. Perhaps we should do this again some time soon?" Knock Out offered, giving his Conjunx an endearing gaze.

"It's always a pleasure trying new things with you, doc." Breakdown mumbled before he kissed the top of his helm as they both fell into recharge.

HMMMMMMMM MINIMUS GETTING PEGGED BY LARGE FEMME BOT S/O??????????

Minimus Ambus/Femme Reader (Aft Play - DL;DR)

He was on his hands and knees, balling the berth sheets in his hands as he nodded affirmatively. You weren't the largest mech aboard the Lost Light by any means, but you still towered over him. The small modded spike attached to your pelvic plating was significantly smaller than your usual ones, but those were for interfacing with his valve. Today, he wanted something else.

He had approached you even more intimately reticent than usual as he stated the request, apologized, and then immediately tried to leave. Minimus seemed genuinely shocked when you agreed, even moreso when you told him you were excited by the idea of using a toy to interface with his aft port.

It had taken him a few days to build up the courage to do so, but he had already picked out an appropriate toy and decided to prepare himself to make the process easier. As always, you could never say you disagreed with his results.

Now you let your thumb caress the edge of his exposed aft port before you gently removed the little black plug he had worked inside himself. A small bit of lubricant leaked out as you pulled it away and you traced the rim to collect it before pushing it back inside with the tip of your finger. The puffy mesh was loose and wet and your thumb slipped inside with ease, calipers offering no resistance as you pressed a little further in to test his limits. He was more than ready.

"Y/n, I've been preparing all day." He huffed out through labored vents. "Please, continue!"

"You'll tell me if I need to stop?" You ask as you line up the spike with his port.

"Y-yes." He whimpered, balling his fist into the soft berth sheets as the tip nudges against the pliant protoform. "I'll be fine, Y/n, just- please, begin."

"Anything for you, Minimus," you tell the mech as your larger servos encircle his small hips to hold him steady. He muffled a cry into his fist as you slowly pushed inside.

Even with all his preparations the fit was still a tight one, but the impatient rocking of his aft told you Minimus was more than pleased by the intense fullness.

It felt like hours passed until you bottomed out and your hip plating finally bumped against his own. His field flared in slight discomfort and you held still. You petted a hand down his back to comfort him, waiting for his frame to adjust to the spike.

"Y-you can move now, Y/n." He said after a moment, field no longer radiating discomfort. Now you could only sense his desire, hot and desperate as it raged through his normally reserved field.

"So perfect for me, Minimus," you tell the small green minibot as you pull out and start a slow, shallow pace that has his red optics flaring. "I'll take good care of you."

UM 100% gets pegged but the only person remotely big enough is Megatron so can i get some of that please? i love your writing so much 💗

//Idk if you were asking for aft stuff but that's what you're getting//

Magnus wanted to bury his face in his pillow. He definitely would be doing that, if Megatron hadn't insisted on flipping him onto his back for this. Another hot, clipped moan left Magnus' vocalizer and he wondered why he was doing this at all.

Megatron's digit tip pushed just past his tight entrance. It was a completely different, foreign feeling, not at all like what the ex-con's digits felt like in his valve. Magnus had only had his aft port taken one one other occasion- and it was by Megatron that time, too- and he'd forgotten what it felt like. If they were doing anything else, Magnus would be putting on his usual sorry act of trying to be sensual in any way, but not like this. Like this, he felt exposed.

Megatron pulled back, glancing over Magnus' fame and making him shiver. "Do you feel okay? Do you think you're ready?" Megatron asked. Magnus' gaze dropped from Megatron's optics to his stiff spike, and he nodded. "Use your words, Magnus." Megatron shot back almost immediately. Right, words, Magnus had forgotten that his partner preferred that.

"I am," He responded, though his voice was already barely crackling with static.

Megatron's hips took up the space between Magnus' thighs, and the blunt head of his spike, coated with both artificial and natural lubricant, nudged at Magnus' tight port entrance.

"Stop me if you must," He reminded Magnus before beginning to push in.

Magnus' lips immediately parted in a gasp at the gradual sting that raced up his spine. He clenched his dentae, engine snarling a low, angry note as he tried to bear it. He could feet each inch and every caliper stretching to accommodate Megatron's girth and all the textured ridges along his spike. His engine stuttered and his thighs trembled around Megatron's frame when he felt a sudden lurch of hot pleasure shoot through him.

"Are you doing okay?" Megatron asked, pausing and smoothing a servo gently over Magnus' abdominal plating. The other mech nodded before remembering and giving a verbal agreement. Only after that, and Megatron giving him another glance over, did he resume. Magnus hadn't remembered ever feeling so full before.

Megatron's spike raked over each of the sensitive nodes and calipers as he pressed in, Magnus' breath quickening as his vents started to struggle to keep his temperature down. Just when it started to feel like he couldn't take anymore, he felt the familiar weight of Megatron's hips pushing flush against his own. He lifted his helm from the pillow he'd dropped it on to see his partner lovingly rubbing slow circles into the portion of Magnus' hip plating they his thumb was over.

"How does this feel?"

"Tight," Magnus hissed, resisting the urge to squirm and writhe. It almost hurt, but he wanted more. He wanted Megatron to hold him own and take his aft port as he would his valve, but Magnus himself knew that he would break if Megatron tried that. "K-keep going, please,"

Slowly and steadily, Megatron set a gentle pace. Barely enough to have Magnus bouncing and shifting on the berth, but it still made him moan and huff.

"Megatron!" Magnus yelped on a particularly hard thrust. His partner kept that new pace of sharp, real thrusts and Magnus could feel optical fluid brimming in his optics when he squeezed them shut.

His vocalizer barked out clipped moans and cries, his charge already cresting towards its peak. Suddenly, Megatron wrapped his servo around Magnus' spike and tugged almost too roughly and it had Magnus crying out a staticky, messy moan as his climax crashed through him.

Just as he was about to come down into overstimulation only to be tripped off into another overload by the sensation of hot transfluid flooding into him and rushing out along his plating. He sobbed, optics brimming with optical fluid as he shuddered and his spike coated his chest in another load of his own transfluid.

"Megatron, oohhh," Magnus sighed, bringing his servos up to wipe at his optics. Megatron leaned down and kissed the other's forehelm, then his jaw, then he claimed his lips. Magnus was tired, but not so much so that he wanted to fight back or stop. The warmth was welcome, even though he felt his processor trying to get him to recharge.

Recharging was always a welcome step thar came after. After Megatron had taken care of him, cleaning him up, kissed him and told him how much he appreciates him. Recharging in his arms was always welcome.
