Now that they could move, Optimus found himself laying on his back on the berth while his mates stood over him, pleasure shot optics staring down at the submissive Prime. While Landmine and Jetfire knew that they needed to be careful due to Optimus carrying the Matrix of Leadership, but that didn't mean that they couldn't pleasure the submissive bot. Optimus felt the touches this time, and they were more like what his systems had been begging for and craving, and he moaned in pure pleasure.
Jetfire smiled at that, "oh look at that, we have a needy Prime on our hands" Jetfire said as he stroked Optimus' stiff spike, causing the port of the prime to become wetter.
Landmine smirked, enjoying all the mewls and moans that Optimus let out. "Looks like our special bot is looking for something more" Landmine added, his spike teasing the rim of Optimus' port, causing the Prime to moan more. Jetfire smiled, and shot an idea to Landmine who smiled, as the idea seemed perfect.
Jetfire rolled the Prime onto his side and then Jetfire laid behind and slid into Optimus' exposed aft opening. Optimus stiffened for a moment at the sudden unexpected intrusion but then went back to moaning in pleasure. Landmine laid on the other side of Optimus and slid into the front port, causing the Prime to feel two spikes inside of him from two different directions and sides. Optimus fully gave up then and allowed his mates to take him to new heights as they fragged. Optimus' systems were merely waiting for just the right time to release his spark.
"Alright, Prime, release that submissive spark of yours" Landmine barked as an order. The Prime's eager and submissive spark came out, looking for the sparks of Landmine and Jetfire. The pair soon released their own sparks and all three ran into each other hard, uniting the the three and knocking up Optimus at least, though no one could tell if he was the only bot who became sparked because the joining was so bright and all three mates had their optics closed. Optimus could finally feel his systems relax from before even if he didn't fully understand why. Optimus was soon out cold, after his spark returned to his systems.
Jetfire and Landmine smiled. "I think we wore him out" Jetfire piped up.
"I agree, but hopefully this session was fruitful" Landmine added. Both agreed before curling up with the out of it Prime. Soon, all would be revealed.
