Prima felt bad, terribly so, as he listened to the Primes talk in their shared living room of their housing level and only focused on Megatronus. The strong Prime was conversing with Quintus while Prima currently had a servo pumping his spike in the shadows. What he would do for Megatronus to be with him, but a small sense of envy escaped him at the attention Megatronus was giving to everyone but him.

With a hiss, he marked a corner of the room silently and put away his spike in shame. It was out of sight, out of mind as long as no one went to that corner specifically. He tried to cover it casually with curtains just next to him in the windows before meeting up with Alpha Trion like nothing happened. He did keep an eye on Megatronus wondering what to do about his attraction to him. There was no way around it.

Afterwards, there was a meeting in their fortress across from their home building and Prima was very reluctant to go right now. He was moody and it helped none Megatronus sat two spots near to him. That was the worst decision ever in their layout. Being the de facto leader of the Primes by creation number, he sat at the head of the table. The second Prime, Vector was on his right side with the third, Alpha Trion, and so forth continuing down the line. Thirteen was on his direct left but Megatronus was right next to Thirteen. He kind of lost track what they were talking about and had little opinions himself about it, too focused and horny that he had his valve open and was stroking it beneath the table out of sight. It helped none Megatronus occasionally looked his way even when he wasn't talking.

He kept his arm movements to entirely still, just focusing on lightly playing with himself thinking about Megatronus possibly fragging him, and he prayed to Primus silently that it would come true. He kept as still as he could, not letting anyone think something was wrong. As soon as the opportunity to wrap up the meeting was presented, he all but excused them quickly and waited for everyone to leave except...

"Prima, can I have a word?"

The larger Prime let Alpha and Thirteen pass him before letting it slide closed. That left Prima with Megatronus alone. The twelfth Prime chose Thirteen's seat to be right next to Prima now, and that was an even worse mistake than the normal arrangement. He started rubbing himself harder. Megatronus had no idea.

"What's wrong?" Prima asked. He felt droplets of lubricant starting to moisten his valve and his desperation climbed in his faux calm state.

"You seem out of it. You have been for the past few days. I know because I study everyone, and something isn't right about you."

Oh, Primus, his voice. Deep, thunderous if rageful, and demanding. Prima tried his hardest not to show he was close to coming undone as his digits now performed rapid circles over his sensitive region.

"I have no idea what you mean," he managed to get out.

Megatronus wasn't buying that and furrowed his brows. "Enlighten me."

Prima couldn't take much more. To his embarrassment, he had to cover his mouth and close his optics at the painful situation he just made for himself. Megatronus saw this and his suspicion skyrocketed until he suddenly looked under the table-

"Prima..." Megatronus shot back up in disbelief but amused. "You mean to tell me the entire meeting...?"

Prima rubbed his optics with his free servo. His other had lubricant on it. He heard Megatronus sigh with a small laugh then heard the other chair move closer. Abruptly, Prima's servo was shoved away and two foreign digits breached his entrance making him squirm and sink in his seat. Megatronus' left servo palm covered his exterior node and with his rough motions managed to simultaneously antagonize it and slam the digits into the valve. His right servo gripped Prima's chair.

"You seem a little too excited I'm helping you. That makes me curious if it was me you were imagining," Megatronus sneered.

He was too focused on the digits abusing his valve to make a statement about it without coming off as a hypocrite. His servo went over Megatronus' and tried to force the digits deeper, instead prompting Megatronus to insert another digit and kiss him. He moaned into the other's mouth and clenched his thighs as a mind-numbing overload hit him. They broke apart when Megatronus had a vicious smile with his two sets of canines making Prima blush.

"The next time you do something like this, just know some of us might be a little more familiar with such activities to know when you're lying about it. You aren't the first of us to do this, but I was never caught."

That made Prima look at him stunned. "You..."

Megatronus simply mused, "Some parts of our abode aren't as clean as you think. More specifically, I really love using that table in the lounge room when everyone is still home in the other rooms. Adds a little tension to the experience."

Prima just stared at Megatronus walking out and made the Prime leader immediately think about that. When he finally returned to their shared tower complex, he passed Megatronus who merely winked and then he went to the lounge room only a few Primes ever truly used. There was a table with a corner of it slightly worn by some type of activity. It dawned on him Megatronus had been relieving a lot of stress on it, and he was about to as well.

As he heard the other Primes moving about, he revealed his valve again and pressed it to the corner of the table. He gripped the other edges of it to keep steady as he rocked against the newly blissful sensation. He hoped Megatronus would carry on after him; the idea of them sharing the same spot to play at only heated him further.

All Prima could do was continue and drag his valve across the corner thinking of Megatronus. While he wanted the mech to take him, this was the next best thing. And he didn't regret being caught now.

AN: Megatronus was probably the third most sought after Prime behind Solus and Micronus if lore was correct. I would believe it. Who wouldn't want to be railed by this guy?
