you encountered Megatron a few times as am autobot while he is a decepticon though ironically when you were both left behind by mistake on a deadly tundra planet did the two of you work together to survive and stay warm until rescue came though it came at a cost because low and behold you both ended up becoming Conjunx Endura's! Or sparkmates which you both didn't realize until Megatron started to feel off not being near you after like a year so almost desperate move on his part he snuck onto the ship where you were. Megatron carefully dodged being seeing by autobots until he found you in your berth room trying to do some work which gave Megatron the opportunity to sneak in which he did after nearly getting caught but he manged to slip into your berth room without being seen now that he's near you, he couldn't help but pull you into his arms and deliver a long but desperate kiss which caught you off guard seeing Megatron of all being here and kissing you until he pulled back and spoke "so your my Conjunx Endura huh?" your optics widen realizing what he meant but before you could respond did he pull you close kissing you once more but more passionately which after a moment did you kiss back which led to a night of passionate love making between the two of you~ though the next morning Megatron felt much better and carefully snuck away back to the decepticon base before anyone noticed he was gone to see you unfortunately you both slipped up because Megatron is now carrying your sparklings which he discovered almost seven months later and unfortunately he's carrying them to full term and have to tell you or nothing good would come from this so one night Megatron made a plan and snuck back to your room almost seven months later and told you which surprised you alot like alot alot but after some thinking did you allow Megatron to stay with you until the sparklings are born you just need to make sure your both not caught or disaster may strike so tred carefully now...
