He was skeptical at first. Giving up his position as the dominant one really was unheard of even in his own mind. To him, submission was weakness. But on the other hand, that was only applicable during battle since the berth was different. As long as it wasn't in public or anybody in general saw it, he didn't exactly care too much.

Lying on his back, Megatron's legs had wrapped around his mate's waist rather aggressively as he felt Ultra's spike ram inside. The pressure on the nodes within his valve flared violently, delightfully enough that a feral grin began to spread across his heated faceplates. It was a type of pleasure he was not familiar with but found it to be a modest experience, he dare say. Now he knew why his consort loved it.

The change of roles did the Magnus a bit of good as well. As fun as it was to be stretched, being able to pound someone to oblivion was a welcome pace that made him feel like he had to work for it. A satisfying reward would come of his efforts which made his position much more important. Of course, there was the slight issue of the chassis size difference. He was huge mold for an Autobot but compared to the Decepticons, he was far from the largest mech. He was as big as Starscream who was three heads shorter than Megatron. He was basically trying to frag someone more than a quarter larger than he was. Apparently he wasn't failing.

"Are you alright, Megatron?" He panted as he drove his member deeper.

The helicopter's servos dug into the surface he rested upon, his backside arching. "I-I'm fine… just don't…don't stop!"

Smirking, the military truck lifted his partner's hips and sank himself to the hilt, admiring how tight Megatron was. Slowly the charge of the overload incoming built rapidly, too fast in fact but he knew his mate was just as unstable.

Megatron growled. He felt on fire, his body roaring so maliciously but who was he to fight the glorious pleasure that was? He did nothing but let Ultra take complete control. As the Magnus leaned over him, over his chest more so, the warlord sat up so he could capture the lips of the mech. The kiss was rough but did not stall any movements between the two. His own twisted smile reformed when his mate gave a sudden yelp when he drew Energon. Instead of reeling back, his consort simply shook his head. From time to time, Ultra would be the victim of a bloodlust which he never found any reason to complain about. The fact that he dealt with it like a normal occurrence was amusing.

A rush of heat began to blind both of them. They were so close. The silver mech clung to the Magnus vigorously, rocking against each thrust until finally his access port contracted and a gush of transfluid from Ultra triggered him into his own overload. A guttural scream he neglected to conceal burst out of his vocalizer, his servos nearly denting the blue armor. His consort pressed against him in response, holding Megatron as steady as he could.

When both their charges died down, Ultra nudged the Decepticon insignia with his helm. He did not remove his spike from the sore valve as he awaited Megatron's approval but found the feeling comforting just as him being filled was. The latter of the two huffed in contentment, his valve still twitching with the appendage inside. All he had to do was give his equal one glance and the other didn't hesitate to retract. His valve then began to grasp air and a slight chill of emptiness shuddered through him.

"I'll admit that wasn't…too bad," Megatron mewled, watching some of the fluids leak out of his opening.

The Magnus raised a brow, "You want to do this more often-?"

"I'd rather this become a 'once-in-a-blue-moon' occurrence as the humans would say, if you don't mind. I like being the dominate force more than the submissive one but that doesn't necessarily mean I didn't enjoy it. It's just not really my thing."

Ultra all but snickered as he was dragged back into Megatron's arm when the tyrant suddenly purred, "Now, let's see if we can match that experience the other way around, shall we?"

It took less than a second for Ultra to be under his mate and knew very well where this was leading to despite his slight exhaustion. Maybe submission wasn't Megatron's thing but it was rather exciting while it lasted.

AN: Yay! Another UltraMega fic! This pairing is one of my favorites, not gonna lie! Had fun with this one and I hope you enjoyed it as much as I have!
