—————————————————————————————————
As Ratchet grinded himself against Optimus's thigh, the Autobot leader couldn't help but watch in fascination. He had never seen Ratchet act so boldly before, and the sight of the medic rutting himself faster and faster against him was both arousing and surprising. Optimus felt Ratchet's hands grip onto his shoulders for leverage, and he could sense the intense desire emanating from the smaller Autobot. He wondered what had gotten into Ratchet, but he couldn't deny the effect it was having on him. Just as Optimus was about to speak up and ask Ratchet what was going on, the medic abruptly stopped and pulled away, leaving Optimus feeling unsatisfied and confused. Later that day, Ratchet showed up to Optimus's quarters wearing nothing but one of Optimus's oversized shirts. The sight of Ratchet's bare legs and chest peeking out from underneath the shirt was enough to make Optimus's spark race. Ratchet sauntered over to Optimus, a seductive gleam in his optics. "Do you like what you see?" he asked, running his hands up and down his body. Optimus growled and grabbed Ratchet pinning him down. Ratchet gasped in surprise as Optimus pinned him down, his optics darkening with desire. "Oh, you like it rough, do you?" Ratchet teased, a smirk playing on his lips as Optimus snarled lowly. Optimus leaned down and claimed Ratchet's lips in a fierce, possessive kiss. He could feel Ratchet's body trembling beneath him, and he knew that the smaller Autobot was enjoying this just as much as he was. As he continued to devour Ratchet's lips, Optimus's hands roamed over the medic's body, taking in every curve and contour. He couldn't resist the urge to grind his own growing arousal against Ratchet's thigh, feeling the smaller Autobot squirming beneath him. Finally, he pulled away from Ratchet's lips and began to trail kisses down his neck, his hands sliding down to grip Ratchet's hips. Ratchet moaned and arched into him, his body already on the verge of complete surrender. But Ratchet wiggled away and smirked running off leaving Optimus annoyed and horny. Optimus had had enough of Ratchet's teasing. He was tired of being left unsatisfied and frustrated. So, he decided to take matters into his own hands. He quickly caught up to Ratchet and grabbed him by the arm, pulling him close. "Enough of this teasing, Ratchet," he growled. "You want me? Then you're going to get me." Without another word, Optimus spun Ratchet around and pushed him up against the nearest wall. Ratchet gasped in surprise, but he couldn't deny the intense arousal that was coursing through him. Optimus growled lowly and tugged at Ratchet's shirt before taking it off leaving Ratchet bare pressed into the wall. Ratchet whimpered as his cock ground into the wall and Optimus pulled his hips back pressing his hole against the primes still clothed cock. Ratchet moaned and clawed at the wall while Optimus ground against his ass, he was so desperate now he felt himself get slick like an obedient omega slut. Optimus chuckled darkly as he felt Ratchet's slickness, his own arousal growing even more. He couldn't resist any longer, he had to have Ratchet now. With a quick movement, he pulled down his own pants, revealing his massive, throbbing cock. Ratchet's eyes widened in surprise and lust as he took in the feeling of the large cock pressing against his ass, he whimpered loudly. "It wont f-fit!" Ratchet yelped as he felt the massive member press against his entrance. Optimus chuckled again, the sound sending shivers down Ratchet's spine. "Don't worry, my dear medic. I'll make it fit," he growled, his hands gripping onto Ratchet's hips. Slowly, he began to push into Ratchet, his massive cock stretching the smaller Autobot's tight passage. Ratchet gasped and moaned, his body trembling with pleasure and pain as Optimus filled him completely. He could feel the bulge in his belly growing with each thrust, the sensation of being so full overwhelming him. But Ratchet didn't want it to stop. He wanted more, he wanted everything that Optimus could give him. With each thrust, he pushed back against Optimus, taking him deeper and deeper. Their bodies moved together in perfect sync, each thrust bringing them closer and closer to the edge. But before Ratchet finished Optimus pulled out denying Ratchet his know and release. Ratchet whined in frustration, his body still trembling with desire. "Why did you stop?" he panted, his eyes pleading with Optimus's. Optimus smirked darkly and pulled Ratchet close, nipping at his ear. "I'm not done with you yet," he growled, his hand wrapping around Ratchet's cock. Ratchet moaned loudly, his body bucking into Optimus's touch. The feeling of Optimus's hand around him was almost too much to bear, and he could feel himself getting close to the edge again. But just as he was about to come, Optimus pulled away, denying him once again. Ratchet whimpered, his body shaking with need. "Please, Optimus," he begged. "I need to come." Optimus chuckled darkly and spun Ratchet around, pushing him back up against the wall. "Then beg for it," he growled, his hand wrapping around Ratchet's cock again. Ratchet moaned and arched into him, his body trembling with pleasure. "Please, Optimus," he begged. "Let me come. I need it so badly." Optimus smirked and began to stroke Ratchet's cock faster, his other hand gripping onto Ratchet's hip. Ratchet's body convulsed with pleasure as he came hard, his release spilling over Optimus's hand. Optimus continued to stroke him through his orgasm. But Optimus still wasn't done, he planned on making Ratchet never tease him again. He lifted Ratchet's legs up, hooking them over his arms as he continued to thrust into him relentlessly. Ratchet's body was writhing with pleasure, his moans growing louder and more desperate with each passing moment. He was completely at Optimus's mercy, and he loved every second of it. Optimus's massive cock was filling him up completely, stretching him to his limits. Ratchet could feel the bulge in his belly growing even more with each thrust, the pleasure almost too intense to bear. Finally, with a loud roar, Optimus came hard, his release flooding into Ratchet's body. The sensation of Optimus's hot release was enough to send Ratchet over the edge once again, his own release spilling out between them. Optimus growled lowly and panted softly, he didnt plan on ending it just yet though.  He lifted Ratchet up, carrying him over to the berth and laying him down. He climbed on top of him, his cock still hard and throbbing. "I'm not done with you yet, Ratchet," he growled, his hands gripping onto Ratchet's hips. Ratchet moaned and writhed beneath him, his body still sensitive from his previous release. But he couldn't deny the intense desire that was coursing through him. He wanted more of Optimus, he needed more. Without a word, Optimus pushed back into Ratchet, his massive cock filling him up completely once again. Ratchet gasped and moaned, his body arching into Optimus's. The sensation of being so full was almost too much to bear, but Ratchet wanted it all. He wanted everything that Optimus could give him. And Optimus was more than happy to oblige. They lost track of time, their bodies moving together in perfect harmony. It was like nothing else existed in the world except for the two of them, lost in their own pleasure. They went through multiple rounds, each one more intense than the last. Finally, after what felt like hours, they collapsed together, both of them completely spent and satisfied. They lay there, breathing heavily, their bodies entwined together. Optimus couldn't help but smile to himself, knowing that he had finally tamed Ratchet's teasing ways. But deep down, he also knew that he would always crave the feel of Ratchet's tight, hot body wrapped around him.
