Decided to try and write something despite my lack of experience, bear with me.
For reference, the OC I'm using looks like this
Anyway, on with my awful writing!
Sleep, My Dearest
Tarn x Phyto Prime (OC)
Warnings: Smut, dub-con, oral (f receiving), belly bulge, implied mention of cannibalism, blood drinking, Tarn has a knot
Summary: Phyto Prime has been struggling to recharge, Tarn helps her out in an unorthodox way.
It wasn't often that Phyto Prime awoke in such terror. Sure, she was constantly haunted by visions of the Autobots she once called friends who abandoned her, but it never felt this... intense.
The femme heaved a sigh as she sat up on her berth, a servo lifting to cradle her helm. She could feel the start of a processor ache forming, her body begging her to go back into recharge.
She had been exhausting herself lately, trying to stay awake so she didn't have to face the phantoms of her past, not caring about the toll it was taking on her.
She stood and walked over to her door, poking her helm out of her quarters and checking left and right before stepping out. She was just going to take a walk around the Peaceful Tyranny, then she'd go back and rest. Yeah, that was a good plan.
She passed the doors to the DJD's quarters, hoping that she was quiet enough not to rouse them. She briefly paused at Nickel's door, considering if she should let the minibot medic know about what was going on and maybe see if she could prescribe her something...
"What are you doing up, dearest?"
The familiar voice startled Phyto out of her thoughts, making her stiffen as she felt the large frame of her leader press against her spinal struts.
"N... nothing, sir," she responded, her voice quivering. She trembled as she felt Tarn's servos on her shoulder plates, biting back a whine as his touch trailed down to rest on her hinge.
"It doesn't seem like nothing, dearest. In fact, it seems like you're disobeying a direct order." Tarn took Phyto's servo in his, spinning her around to face him. He placed a single digit beneath her chin and tilted her helm up, admiring the look of fright on her features. Such a pretty thing she was...
"I... I didn't mean to, sir, I promise! I just... can't sleep..." She hated how pathetic her voice sounded, wavering and soft. She went silent as he traced the side of her faceplate, trying her hardest to resist the urge to lean into it.
"I know." His words confused her. His servo moved away from hers to rest close to her lower back, guiding her to follow him. "Let's get you back into recharge."
The femme followed along, letting Tarn lead her back to her quarters. She typed in the code to her door and slipped inside, fighting down the flush of energon to her cheekplates. She walked over to her berth and climbed in, laying on her side and shutting off her optics
She startled when she felt the berth sink, her optics onlining again and looking over to see Tarn sitting on her berth beside her. She scooted back a bit to give him room, only to yelp when he grabbed her and pulled her against him.
Tarn forcefully laid Phyto on her back, settling on top of her to keep her pinned. He could feel her trembling beneath him as he pressed his masked faceplate against her neck cables. He hummed softly, enjoying the effect he had on her.
Phyto held completely still as Tarn pinned her down, now restless for an entirely different reason. She had always found him... attractive, and now she was beneath him on a berth with very little space between them. A blush of embarrassment rose to her faceplate.
"Settle," his voice soothed her frantic thoughts, replacing them with one focus: him. She whimpered as he pressed her down further, hoping he wouldn't be able to notice the way her valve began producing lubricant.
Oh, but notice he did. Tarn smiled behind his mask as he picked up on Phyto's arousal, lifting himself off her. His servo trailed down her chassis to rest between her legs, pressing against her panel inquisitively.
"Open up for me, dearest," he whispers into her audio receptor, his voice low and intimate. She submits easily, retracting her panel and baring her valve to her leader. He's looking at her so attentively...
The click that sounds out as Tarn removes his mask snaps her out of her thoughts, and she immediately covers her optics. She shivers as she feels him lean closer, clamping a servo over her intake so she doesn't cry out as scarred dermas press against her anterior node.
"Such a pretty thing you are," Tarn murmers against her valve, extending his glossa and licking a broad stripe along her mesh. He revels in her taste, sweet and oddly floral, before going back in for another lick.
Phyto whines as Tarn lavishes her valve with attention, mewling when he thrusts his glossa inside. She can't help but thrash as Tarn moves it around, devouring her.
It isn't long before she overloads, fluids gushing out of her valve into his intake and onto his dermas. Tarn coaxes her through it with a few more soft licks before pulling back and wiping the stains of her overload off his intake.
"You taste wonderful, dearest," he murmurs as he presses a kiss to her inner thigh before moving up to settle on top of her again. Phyto squeaks in surprise as he kisses her in a way that could almost be called tender. She moans softly as she tastes herself on his dermas and glossa.
"T... Tarn, please..." Phyto hopes that she gets her message across, not wanting to have to say it out loud. Tarn chuckles, deciding to spare her tonight. He retracts his panel, letting his spike pressurize and rest against the femme's valve.
Phyto can't help the way she stares at Tarn's spike, admiring it like she did the first time he took her. His size was considerable, and the red biolights running along the underside glowed just enough to be beautiful. Then, of course, there was the knot at the base that would inflate and fill her just right, she was sure of it. Tarn had never actually let her take him all the way.
She moaned softly as he began to rut against her, her venting hitching when he nudged her anterior node with the tip. "I... I can take it," she reassured, and with her consent, he pressed inside.
Tarn growled as he buried himself all the way in, listening to his Prime mewl beneath him. He lifted himself off her slightly to make sure he hadn't hurt her and was fascinated by what he saw.
Phyto Prime was already a mess beneath him, holographic hair falling to the side and letting him see the flowers growing from her right optic, expression one of bliss. That wasn't what caught his attention, though. His crimson gaze was fixed on the way the plating of her abdomen stretched and bulged around his spike.
He gently placed a servo over the bulge, causing the femme to moan again. He could almost feel himself throbbing inside her. He committed the sight and feeling to his memory banks before he started moving his hips.
Phyto whined and cried as Tarn thrusted in and out of her valve, her volume steadily increasing until he had to press a servo over her intake to muffle her noises. "Do you want to be found out? Do you want your fellow Decepticons to see you like this, writhing under your leader as I take you?"
She shook her helm as much as her leader allowed her, whimpering a soft apology against his palm. He nodded down at her and picked up the pace, ramming his spike into her ceiling node.
Phyto gasped as a rougher thrust had her overloading for the second time that night, biting down on the crook of Tarn's neck cables so hard she could taste his energon.
"There you go, dearest, eat up. I know how much you love it," he whispered to her, his voice sending shivers down her entire frame. She drew back a little before he rested his servo under her helm, keeping her there.
She obeyed the silent request and kept her faceplate buried against where she bit him, lapping up the energon that flowed out, tasting the very lifeblood of her leader. He groaned and picked up his pace from where it had faltered when he was distracted.
"Can you take all of me, dearest? I want to feel you one last time before the next cycle begins." She nodded softly, continuing to clean Tarn's energon. All it took was a few more thrusts and a soft rub to her anterior node before Tarn sheathed himself all the way inside her and felt the weight of both their overloads, filling her with his transfluid as his knot inflated and locked them together in the most intimate way.
Tarn collapsed on top of Phyto, catching himself and rolling onto his back before he crushed her beneath him. She gave a soft cry as she was pulled on top of him by his knot. She was right, it filled her perfectly.
She snuggled up on top of him, sighing contentedly. She was already drifting into recharge when she heard him speak,
"Sleep, my dearest."

"What even happened to you, Tarn! Last I checked, you weren't injured!"
"Nickel‐"
"Na na na, shut it. This needs to be looked at immediately. Why didn't you come to me sooner?"
Tarn looked over at Phyto Prime as she conversed with Kaon, the two probably sharing anecdotes about what they've done on missions and hunts.
"I was... stuck with something," he sighed out finally. Nickel made a face as she understood what he was implying, glaring at him.
"Great. Now I have to worry about if her bite made things worse," the medic huffed. "Did you at least tell her about your feelings?"
"What feelings?" Tarn deflected, tearing his gaze away from the Prime. Nickel kept glaring until he admitted quietly,
"She'll know. Eventually."
