Optimus was standing at the monitor watching for Decepticons, completely unaware that he was being watched. Optimus knew that Prowl was out on Patrol with Bee, Bulkhead was with Sari, and Ratchet was busy in the med bay. Sentinel Prime, Jazz, and Ultra Magnus were on Cybertron, though Ultra Magnus had let Optimus know that he would be getting two new bots on earth, as the Cons seemed to being using the planet as their home base. Optimus asked when the new arrivals would arrive, but Magnus could not say exactly when, as these two were very well known in slipping in. Optimus had no idea what that meant, but having forgotten about the conversation, Optimus refocused his attention on the monitor.
Across from the monitor was a large vent that provided air to the recreation room. Inside the tunnel was a full grown bot who was well known for sneaking in and out of places without being seen as well as being an excellent spy in gathering information. Right now this spy was watching his newest target: Optimus Prime. The spy could not help but think that the young leader was so handsome as he stood there. The broad chest, the pert aft, and the confident attitude of the young prime was revving this silent bot's engines.
Suddenly the lights went out. Optimus was worried as the power had never gone out before. And the stranger thing was that Optimus could not call any of his teammates. Whatever was happening, Optimus would have to handle on his own. Optimus used his own optics as lights to try and see what was going on, but whoever was in the room with him was too nimble and quick for the young Prime.
And just as Optimus was going to check something out, he felt a presence behind him. And while Optimus was startled, something told the young leader that this presence was no threat. Optimus did not relax though, as this was still strange. The bot, knowing it caught its target, began to run his hands along Optimus's backside, finding all manner of sensitive wiring in the young leader's upper torso. Optimus, for as much as he wanted to resist what this presence was doing to him, was too enthralled and filled with lust to try and attempt to stop this presence from taking what it wanted, which seemed like to be the young prime himself.
The mysterious bot smiled, as he ran his hands over the young Prime's body, causing the fire engine to shiver in nervous anticipation and blind lust. And when the mysterious bot whispered something in the young prime's audios, Optimus was too far gone to not oblige, and soon Optimus had his interfacing panel removed, his arousal jetting out from his body stiff, throbbing, and leaking lubricant while his virgin front port was leaking copious amounts of lubricant as well, as Optimus had never found someone who seemed to know his hotspots so well, not even Elita 1 before he had lost her.
Optimus was lost in the sensations as he felt a stiff throbbing arousal near his virgin port. Optimus was overly eager to have that searing hot arousal in his port, but the mysterious bot was gentle, somehow sensing that Prime was a frontal port virgin. Optimus moaned lustfully as the bot bent the young prime over onto all fours and then the mysterious bot slowly and carefully entered the Prime's virgin port while continuing to play with various wires as well as the Prime's hardened arousal. Prime felt the pain when the mysterious bot gently plowed into the young leader's virgin port, but the mysterious bot was slow and careful and gave the young Prime a chance to adjust before the sneaky bot continued pumping, languidly pumping in and out of the young Prime. Optimus was in heaven as this bot loving took the young leader.
Optimus could feel his lust and systems slowly warm as the bot continued his pace, making the whole experience wonderful for both bots. And soon, the mysterious bot asked Prime a question. And through the lust-induced haze, Optimus gave his answer as his spark emerged and floated upward. The mysterious bot was glad to see the lovely sight.
The mysterious bot gently stroked the powerful spark, causing Optimus to moan even more in pleasure-laden bliss before the bot revealed his own extremely powerful white spark, though Optimus did not see it, as he had offlined his optics awhile so that he could just enjoy the wonderful sensations that this bot was giving him. As the two sparks merged, Optimus felt something extremely powerful about this bot that had just taken him, yet this bot was unassuming and quiet. And it was then that Optimus first "saw" his mate before the leader overloaded hard, with his new sparkmate overloading hard into him. Optimus was sure that his new sparkmate had impregnated him, but that did not matter to the young leader, as he would do anything for this sparkmate of his.
After having overloaded into the young leader and after the intense loving session that had indeed impregnated the young leader, the mysterious bot, though slightly smaller than the leader, managed to carry the bigger bot back to the young leader's quarters. The mysterious bot, upon seeing his sleeping mate, curled up on the berth next to the young leader, placing and arm around Optimus. The young spy was thrilled as he had captured the bot he had sought so long as his sparkmate. And with one last kiss, Slugbug sent one last loving pulse to his sparkmate before falling into recharge next to the young leader. Optimus, deep in recharge, smiled, as he felt the loving pulse from the white and gold racer in his own spark. And happy to have found such a wonderful sparkmate, Optimus sent a pulse back.
Elsewhere in the base, the lights came back on. And an Autobot seeker that had been hidden elsewhere in the base, found his way in and was watching the monitor when all the Autobots returned. And once Kryptonight introduced himself to the others, none of the others were worried. Though none of them would learn until later about the bot that had taken their leader as his sparkmate or the fact that Optimus was now carrying sparklings. It was going to be interesting to see what would happen when the rest of the crew found out about what had happened while they were gone.
