Chapter 1: Visitor
Chapter Text
Lyra had come to the arena to surprise Megatronus but he was nowhere to be found, to the point that she knew that something was wrong. Walking down the hallway they had gone down dozens of times she stood in front of it letting the system notify him that he had a visitor. There were groans and the sound of something heavy falling before the door opened and a tentacle wrapped around her abdominal platting, pulling Lyra inside.
Soundwave was standing in front of her, another one of his tentacles held up to show he wanted her to be silent. The sounds were coming from Megatronus’s berth room behind Soundwave’s right pauldron and Lyra could see that the door was shut. Soundwave spoke, “Lyra: should not be here.”
This pulled Lyra out of her shock, “What is going on? Is Megatronus alright?”
Letting his tentacles loosen around her, Soundwave spoke again, “Megatronus: is in heat. Slavers: use to advantage if let in. Soundwave: keeps watch for him.”
Pulling her backstrut so she could stand at her full, if unimpressive height, “I can help with that too.” Seeing the helm tilt and change in Soundwaves visor brightness, “If they think Megatronus has already chosen me as a companion in his heat, they will have to leave him alone during it.” The tentacle dropped farther so she pressed her advantage, “Besides with him out of commision they will find a way to get you into the arena, but I have nothing that will pull me away for another cyber-week.”
Finally Soundwave stepped aside, “Megatronus: is not himself and might not listen to Lyra. Lyra: needs to be careful around him.”
Smiling up at the tall visored mech, Lyra answered, “I’ll find a way to make him listen.” No sooner had the words left her intake than Soundwave was called to the arena. So giving her a pad of instructions/ Megatronus’s refuel schedule he left and locked the hab behind him. After his ped-steps faded Lyra slowly sat down. She had never been around anybot in heat, and was nervous about this. Still, she had to try.
Chapter 2: Struggles
Summary:
This is not going like it is supposed to.
Chapter Text
Trying to get Megatronus to refuel was harder than she realized it would be, with him constantly trying to grab and pull her into the berth with him to frag. But she was quick and his processor was muddled enough that he didn’t realize the regular times she would enter the room.
It was the third day that his system was overheating more than Soundwave’s chart indicated, so she stayed longer in an attempt to find out what was wrong. The next thing Lyra knew a large servo had wrapped around her waist and she was pulled solidly against the heated silver chassis, his intake dropping kisses against her neck-cables as the deep voice talked about how good she smelled as his open panel let a wet, ready valve press needily against her. It took nearly more willpower than she had to pull away and flee the room.
When Soundwave came that afternoon, bringing fuel and new datapads for Lyra she asked him about the change in pattern. He didn’t say a word, just entered the hab and stayed there for two mega-cycles before coming out and stating, “Megatronus: heat coding is in full effect.”
Lyra was startled, “I thought you said there were protocols in place to keep it from doing so. Only making the affected bot more open to interfacing with a presented partner.”
A solemn nod, “Lyra: is correct. However, her presence has changed coding. Megatronus: wishes to take Lyra as a mate.” As if that wasn’t ground shattering enough for Lyra, “Coding: broke though protocols to take mate.”
Pressing her servos together, “So, you are saying that he wanted to mate with me so badly his very coding broke though protocol to make it happen.” If Soundwave thought this was stupid he did not say so, only bending his helm in a nod. Coding breaking though protocol was rare, but not unheard of. Lyra swallowed, “What damage would not mating cause him?”
Soundwave held out a data pad, and Lyra read though how the heat would not abate, only increasing until it slowly destroyed the affected mechs processor as well as other vital systems. She swallowed, knowing what she had to do and actually doing it were two very different things. Looking at Soundwave, “Any advice for a virgin helping a bot through heat?”
Chapter 3: Mating
Summary:
The chapter that gives the fic it's rating.
Chapter Text
Swallowing nervously Lyra walked into the berth room after Soundwave left, looking at the figure on the slab. She stood outside of grabbing range as she called, “Megatronus?” Instantly he was sitting up and reaching for her. Blinking in confusion at her distance she held up a servo as he started to stand, “Do you want me to stay?” He nodded his helm and she motioned to the cube resting on the table beside him, “Then drink your energon.”
Reaching out with one servo he grabbed the cube and drank it, keeping his optics on her the whole time. When he finished and placed it on the table, she steeled herself before crossing the empty space and climbing on the berth with him. Immediately strong arms were around her pulling against the heated chassis, “Lyra I need you.”
Rubbing his servo, “I'm sorry for leaving you so long.” Pressing a kiss against an arm strut by her, “Lay back so I can make it up to you.” The berth shuttered with how fast he obeyed.
Settling between his thighs Lyra found a code she hadn't used outside medical check ups and opened her spike cover. Trying not to let her embarrassment show at the appreciative groan Megateonus let out she used her fingers to measure the size of it. Carefully slipping one after another into the open valve she made sure it was open and slick, scissoring her fingers a bit to make sure. In reality his valve was big enough to take her small spike with no preparation but making sure helped steady her.
After the valve was prepared Lyra removed her fingers, getting a sad noise from Megatronus as he tried to follow them. Her free servo fell to his hip to steady him, “I'm just changing position, no need to fret.” Placing her now slick servo on his other hip she lined her spike tip to the wet valve lips and pressed against it softly. The moan he gave was almost obscene as she slipped into his valve slowly, reaching the base of her small member long before the top of his channel.
There was an almost sob as Lyra started to pull out, large servos wrapping around her hips and abdominal plating trying to keep her inside, “Now Megateonus, I'm trying to make this better.” Seeing the confusion in his hazed optics, “I'm not leaving, just moving a bit.” Rubbing a large armstrut and kissing his abdominal plating as high as she could reach then moving lower, “If you don't like it, we'll try something else.”
Megateonus’s large servos loosened so she could move but remained on her. Giving him a warm smile she started to pull out again but stopped as her tip reached the entrance of his valve before going back in. Her movements were still slow, tentative as she keep checking if he was alright. The servos on her waist clung to her as an anchor as moans and needy keening come out of the large mechs voice box. Moving a little faster she set a steady pace, faltering as her partner reached his climax and started writhing before blacking out under her. Standing still she was starting to panic before he came back to life, moving himself on her member with another needy sound before she started her pace again.
Time blurred together for Lyra after that first session of interfacing. But finally after many overloads on both of their parts Megatronus was finally tired of being spiked and pulled her against his chassis in a hug she could not break even if she wanted to. At that moment though she just wanted to recharge and if Megatronus needed her to be his teddy bear to make that happen then she could work with that.
Chapter 4: Morning After
Summary:
Like the title says, it's the morning after the heat and such.
Chapter Text
Megatronus woke slowly after his heat abated, his entire frame throbbing and his legs/valve aching in a way that showed he would not be walking correctly for orns. What surprised him was the warm frame curled on his chassis, normally gladiators would be used as frag toys during heat and abandoned afterwards to recover on their own. Opening his optics he cycled through twice before he accepted that yes, that was Lyra settled on him recharging peacefully. It took longer than it should have for his logic centers to accept that fact before moving on to the fact that both of their interface panels were open…slag.
Lyra must have felt him moving, “No I am not going to frag you until after you refuel.” She said it in a tone that showed she had stated it many times and followed it with, “You know this.”
“I’m sorry,” his apology must have surprised her because she immediately sat up, “I must have been a servo full.”
Looking down at him, “I’m sorry that I don’t know how to help.” Fidgeting with her servos, “Do you need anything?”
Tilting his helm, “What do you mean?”
Biting her lower intake lip making it even more bruised and kissable, “I never interfaced before, so I don’t know how to take care of a partner.” Shame flowed through him, he took that virginity- a first time that should have been savored and treated with respect - all through his own selfish heat. Knowing there had to be more he turned back into what she was saying, “Soundwave gave me some books about it but they only really say that we need to be careful and attentive in after-care but it didn’t say what to do.”
Megatronus was going to fully question Soundwave, “Just having you here is enough Lyra.” She looked up with a shy smile…before his fuel tank made itself known. Blushing a slight blue, “But some fuel would be good.”
Nodding, “I can do that.” Throwing over her paladron, “I can also draw you an oil bath if you can make it that far.” Adding as an afterthought, “Although a massage could be good for your muscles either way.”
As Lyra’s words turned to muttering the pros and cons of each option Megaronus messaged Soundwave: {Why did you let Lyra state the heat?}
A few moments later a ping showed Soundwave had answered: {Meatronus: desire for Lyra as mate overruled protocol. Had to take mate or melt. Lyra: made the decision knowing this.}
Sending his friend an acknowledgement Megaronus started to stew in his own guilt, his own system could have melted and shut down forcing Lyra into a choice. Of course she did what she had to in order to save a life, that is just what kind of bot she is. And the way she spoke to him at first, almost to an unruly child that kept grabbing something in the archives when she had already told them no.
“Mega,” that soft nickname normally saved for when something was wrong, “Are you alright?”
Forcing a smile, “Of course, why wouldn’t I be?”
Biting her poor lower intake lip again she reached out a servo to tap between his optics, “Because you're wearing your ‘fretting frown’.” Holding out the mug of warmed entergon, “Drink your fuel and listen to me.” He obeyed, sad that their friendship would be over and he would never see her again.
Lyra took a deep breath, “I have wanted to be romantic with you for a while, but I have never known how to start because you are my first romantic partner in any form.” Holding up a servo to keep him from speaking, “No I did not expect to interface with you so soon as I have been wanting to ask to go slowly with you as you probably don’t have the best experiences in that area and until a few orns ago I had no experience at all.” Servos picking at each other she continued, “So I am wondering if we could go back a few steps in the relationship to early dating and only adding holding servos to what we normally do.”
Megatronus stared at her, shocked. He was so focused on preparing himself to be told she did not want anything to do with him, but here she was offering a chance at an actual relationship in spite of everything. Fear was starting to creep into her optics and he quickly reset his voicebox, “YES!” She was startled enough to jump and he took a deep breath, “I would love to date you and start at the beginning.”
Clapping her servos happily, Lyra smiled, “Good.” Swallowing nervously, “For now though I still need to take care of you after,” motioning to the very soiled sheets, “all of that.” Tilting her helm, “Do you think you can make it to the washracks to soak in an oil bath? Or should I bring oil here to massage you.” Reassuring her he could make it to the bath Megatronus finished his morning fuel a very happy mech.
