—————————————————————————————————-
Optimus, Nitro, and Riot were forced to stay in the same room together due to an unexpected situation. It was a long and uncomfortable night, and when it was time to sleep, they found themselves unable to get any rest. Nitro and Riot were twins sharing a spark so they felt each others arousal while Optimus was curled up on the side trying desperately to stay quiet as he wiggled against the sheets, Riot huffed softly and sat up to stretch getting an idea and smirking. "Hey, Optimus," Riot whispered, crawling over to where the other mech was curled up. "I couldn't help but notice that you're feeling a little...frustrated." Optimus blushed, feeling embarrassed at being caught. "I'm sorry, I didn't mean to make it obvious," he said softly. Riot chuckled, his hand running over Optimus' chest. "It's okay, love. We're all feeling the same way. How about we take care of each other?" Nitro woke up at the sound of their conversation and immediately crawled over to join them, his hands running over Optimus' thighs. "Yeah, let's do it. We'll make sure you feel good, Optimus," he said with a grin. Optimus couldn't believe what was happening, but he felt a stirring of excitement in his spark as the twins began to explore his body. They kissed and licked their way down his chest, their hands trailing over his skin. Optimus moaned softly, feeling his arousal growing with every touch. "Yes, please," he whispered, his body arching up into their hands. The twins took turns pleasuring him, their hands and mouths working together to bring him to the edge of ecstasy. But no one was satisfied just like that so Nitro bit down on Optimus' shoulder and the Prime keened loudly, startling both twins. Optimus blushed and hid his face with his arms trembling slightly, but the twins could see the desire in his eyes. "Don't be embarrassed, Optimus," Riot said softly, leaning in to kiss him. "We all want more, don't we?" Nitro nodded in agreement, his hands roaming over Optimus' body. "Let's make this even better," he said with a wicked grin. The three of them moved to the bathroom, eager to explore each other even further. The twins stripped Optimus quickly and grinned at the sun kissed pristine skin that greeted them. Optimus was surprised at his own willingness to experiment, but he couldn't deny the pleasure that came from being with the twins. Riot pushed him up against the wall, kissing him deeply as Nitro knelt down in front of him. He took Optimus' length into his mouth, his tongue working magic as he brought him to the brink of release. Meanwhile, Riot was working his way down Optimus' chest, his hands squeezing and teasing his nipples. Optimus moaned and shuddered, feeling the pleasure building inside him. He couldn't believe how good this felt, how much he wanted it. And when Nitro pulled back, his hand working expertly over Optimus' length, he knew that he was going to come hard. But thats when Riot grabbed the base of his cock and backed up his release, Optimus mewled and whimpered weakly glaring at Riot as Nitro continued to suck him. Riot grinned wickedly, enjoying the power he had over Optimus' pleasure. "Don't worry, Optimus," he said, his breath hot against the Prime's neck. "I'm not going to let you come just yet. I want to make this last." Optimus moaned in frustration, but he couldn't deny the pleasure that came from being denied release. He felt himself getting harder and harder, his arousal growing with every passing moment.
As Nitro continued to suck him, Riot moved his attention to Optimus' nipples, teasing and pinching them as he kissed and licked his way down the Prime's chest. Optimus writhed with pleasure, his body aching for release. But Riot wasn't finished yet. He moved down to Optimus' hips, kissing and nipping at the sensitive skin there. And then, without warning, he buried his face between Optimus' thighs, his tongue flicking over the sensitive skin there. Optimus cried out, his body arching up into Riot's mouth. He had never felt anything like this before, the intensity of the pleasure overwhelming him completely. Nitro continued to suck him, his hand moving faster and faster over Optimus' length. And then, finally, with a loud cry of pleasure, Optimus came, his release spilling into Nitro's waiting mouth. But the twins weren't done, both of them were kneeling infront of Optimus now as Nitro licked his lips and purred, neither of them had release and they planned to use Optimus fully before thinking about sleeping. Optimus whined softly, feeling drained but still wanting more. "Please, I want to make you feel good too," he said, his voice barely above a whisper. The twins grinned at each other, knowing exactly what he meant. Optimus panted softly and slid down to the ground crawling into Nitro's lap and nuzzling his neck whining softly when Riot pulling his hips out and slid him half out of Nitro's lap. The twins positioned themselves on either side of Optimus, their lengths hard and ready for action. Nitro leaned in to kiss Optimus, his hands running over his body as Riot positioned himself behind him. And then, with a slow and steady push, he entered him, his length stretching him open. Optimus moaned loudly, feeling the pleasure building inside him once again. The sensation of being filled up by both twins was almost too much to bear. But he didn't want it to stop. He wanted more. And the twins were happy to oblige. They moved in sync, their lengths sliding in and out of Optimus with ease. The pleasure was almost too much to bear, but Optimus wanted it all. He wanted them to take him completely, to use him for their pleasure. And that's exactly what they did. They fucked him relentlessly, their movements becoming faster and more intense with every passing moment. Optimus came a second time arching between the twins and clawing at Nitro's shoulders while Riot grunted softly and came after him making Nitro follow after, Riot purred and nuzzled Optimus' shoulder gently and pulled out a plug with a grin. "Don5 think were done with you sweet thing~ your body is so willing for us." He purred carefully sliding out with Nitro before plugging the Prime making him whine and clench around the mass amount of seed inside him  and the plug. Optimus was completely spent, his body trembling with pleasure and exhaustion. He couldn't believe what had just happened, how the twins had taken him completely, and how much he had enjoyed it. He looked up at them, his eyes filled with wonder and gratitude. "Thank you," he said softly, his voice barely above a whisper. The twins grinned at him, feeling a sense of pride in what they had accomplished. "Anytime, Optimus," Nitro said with a smile. "We're always here for you." Riot nodded in agreement, his hand running over Optimus' back. "And who knows," he said with a wicked grin. "Maybe we'll do it again sometime." Optimus blushed, feeling a stirring of desire in his spark at the thought. "But for now, you can rest. We'll see you ready you are in the morning yes?" Nitro says picking Optimus up and taking him to the shower to wash him off before taking him to the bed and lending him a shirt, he then went to Riot and chuckled to see the smaller twin already asleep against the wall. Optimus smiled gratefully at Nitro, feeling a sense of warmth and comfort in his presence. "Thank you," he said softly. "I really appreciate everything you've done for me tonight." Nitro grinned at him, his hand running over Optimus' hair. "No problem, Optimus. We're all in this together, and we'll take care of each other." Optimus nodded, feeling a sense of closeness with the twins that he had never experienced before. As he drifted off to sleep, still feeling the plug inside him, he knew that he would never forget this night, and the incredible pleasure that he had experienced with the twins.
