Description - You accidentally walked in on Optimus and Megatron interfacing. I'm sure you all know where this is going 😉

⚠️ Warning!: Contains DP threesome smut ⚠️

Autobot and Decepticon. This was a time of peace, where both were united though the lawful romance of their leaders. Those could chose either side they wished, it wouldn't make a difference now that the war was over. But me, I was stuck between the two. I loved both Megatron and Optimus deeply. I was the one that brought them together. As happy as I was for the two, I couldn't help but feel lonely now that I lost my chances with ever becoming something more to the gladiator or Prime.

Seeking attention, I decided to pay a visit at Omega One, the Autobot base. I knew talking to Optimus would cheer me up. He always gave me a welcoming smile whenever I showed up. He was more committed to expressing his emotions than Megatron who was shallow. The warlord had changed a lot though. The innocent and genuine soul of the Prime must of rubbed off on him.

I arrived inside the base expecting to run into Ratchet and his usual snotty attitude, but there didn't appear to be anyone present upon entering the main haul.

'They must be out on a retreat or something', I thought in my helm. I don't blame them. I would too now that there was no more need to attend the stations at all times. Still curious as to whether or not the base was empty, I decided to roam around and quickly check the dorm rooms.

I stopped when I came to Optimus Prime's door. The absence of everyone else had me believe that he wouldn't be in his own dorm, but I was still hesitant. Slowly, I reached for the door with a hard gulp and walked through. My optics shot open and I stopped in my tracks when I saw two large figures on the berth. The room was dim but I could clearly see the curvy shoulder plates of the gladiator that was on top. He was thrusting himself into Optimus with low grunts. They were too busy engaging each other with their mouths that they didn't hear me walk in at first. They both paused when they heard a faint gasp. Optimus and Megatron broke apart when they realised I had caught them in the middle of interfacing.

"(Y/n)!", the Prime uttered shamelessly. He looked terrified. My face was beet red.

"Oh my Prime! S-SORRY!", I apologised looking away from the unintentional peep show. I was just as embarrassed as him. Megatron wasn't at all flustered like the Autobot he was just fragging a few seconds ago.

"Looks like we have a little spectator Optimus", the warlord chuckled in a low and gruff tone. I shook my helm rapidly.

"N-no! I was just...I wanted to see if...". I tried to deny him but my words weren't coming out right. I couldn't even come up with a proper sentence for Prime's sake. I wanted to explain to them that I had only come by to visit Optimus, but I wasn't expecting to find him here with Megatron doing the most embarrassing thing that I could of possibly walked into. I just wanted to leave and forget this ever happened.

"There's room for a third (Y/n)", Megatron said bluntly. I turned to him shocked at what he had just said. Did I really hear him correctly? Or was he just pulling my cables?

"What?!", I exclaimed. Optimus was looking at the gladiator with the same expression.

"Megatron, that sounds highly irrational", he said with concern.
