Optimus x Ratchet

Prompt/s: Ratchet rides Optimus's thigh
Alpha/Beta/Omega dynamics
Hand fetishization (Ratchet likes how big Optimus' servos are compared to his)
——————————————
Ratchet had always admired Optimus's servos. They were so big and strong, capable of crushing metal with ease. He had always found them incredibly attractive, especially when they were wrapped around him during interface. As an Omega, Ratchet had always been drawn to strong Alpha mechs like Optimus. He couldn't help but feel a sense of safety and security when he was with him. Optimus was going into rut soon and naturally pulled away from Ratchet, the omega hated it when Optimus pulled away from him. He loved the way that Optimus's servos felt on his body, and he craved his touch. But he knew that it was necessary for Optimus to go into rut. It was a natural part of their Alpha/Beta/Omega dynamics. Ratchet tried his best to focus on his work, but his mind kept wandering back to Optimus. He wondered what he was doing, if he was okay. He missed his touch so much. Finally, after what felt like an eternity, Optimus emerged from his quarters. He was in full rut, his plating gleaming with sweat. Ratchet could feel his own body responding to Optimus's pheromones, and he knew that he needed to be with him. Without a word, Ratchet climbed onto Optimus's lap, straddling his thigh. He could feel Optimus's hard plating against his interface panel, and he moaned softly. Optimus wrapped his servos around Ratchet's waist, holding him close. Optimus growled and shifted but Ratchet shushed him gently. "Its alright alpha, im here to help you." Ratchet purred softly, he loved how even as an alpha Optimus would listen to him. Optimus nodded, trusting Ratchet completely. He knew that Ratchet would take care of him, even in the midst of his rut. He relaxed back against the berth, letting Ratchet take control. Ratchet began to grind against Optimus's thigh, his body responding eagerly to the touch. He loved the way that Optimus's servos felt on him, and he couldn't get enough. He reached out and stroked Optimus's servos, marveling at their size and strength. Optimus gave a small chuckle and let Ratchet mess with his servos, claws and fangs dropping from his rut but he was careful to not scratch his omega not yet atleast. Ratchet couldn't help but notice the changes in Optimus's demeanor as his rut took over. But he wasn't afraid. He trusted Optimus completely, even in his most primal state. As Ratchet continued to ride his thigh, he felt his own body responding eagerly to the touch. He reached down and touched his own interface panel, sending waves of pleasure through his body. The sensation of grinding against Optimus's thigh was almost too much to bear. Optimus had enough of the teasing and with a snarl pushed Ratchet back onto the berth and rubbed roughly at his panel, his own large spike slipping from inside its housing as he growled at Ratchet. Ratchet gasped as Optimus pushed him back onto the berth. He knew that Optimus was taking control, driven by his rut. But Ratchet wasn't afraid. He trusted Optimus completely, even in his most primal state. He looked up at Optimus, feeling a sense of excitement and anticipation. Optimus growled as he rubbed roughly at Ratchet's panel, his spike throbbing with need. He could feel his rut driving him wild, and he knew that he needed to claim Ratchet as his own. Ratchet moaned as Optimus's rough touch sent waves of pleasure through his body. He could feel his own valve dripping with lubricant, eager to be filled by Optimus's spike. Ratchet whimpered and let his panel slide back offering himself for Optimus to use, the alpha grinned and nuzzled against Ratchet's neck searching for the scent glands he knew the other mech had. Ratchet gasped as Optimus nuzzled against his neck, searching for his scent glands. He knew that Optimus was fully in the grip of his rut, driven by his primal instincts. Optimus found Ratchet's scent glands and began to nibble and lick them, sending waves of pleasure through Ratchet's body. Ratchet moaned in pleasure, feeling his body responding eagerly to Optimus's touch. Ratchet mewled and arched desperate for something to fill him and Optimus, sensing his mates desire, finally snapped his hips forward into his omega's waiting valve. Ratchet cried out and clawed at the berth, his own omegan fangs dropping so quick he swore he tasted energon but he didnt care. Ratchet sobbed in pleasure and tilted his helm back baring his mating gland where Optimus had already claimed him before, his servos scrambling to Optimus' nexk and tugging the larger mech's helm closer to his neck with a needy whimper. Optimus took the hint and latched onto Ratchet's mating gland, marking him as his own once again. He could feel his own body responding eagerly to Ratchet's tight heat, and he began to thrust harder and faster. Ratchet moaned and writhed beneath him, his body responding to Optimus's touch. He could feel the pleasure building inside him, and he knew that he was close to overload. He knew he had to wait a little longer, he wanted to wait for Optimus' knot. He wanted to fuck himself on his alpha's knot and that thought alone made him whine and arch nuzzling his helm into the crook of Optimus neck where he marked the mech and nibbled on the mating scar with a purr. His smaller claws dragging strips of fabric from the sheets before he moved them back to Optimus' neck and back latching onto his mate. Optimus growled in pleasure as Ratchet marked him, his own rut driving him wild. He knew that he needed to knot Ratchet, to claim him completely as his own. With a final thrust, Optimus buried himself deep inside Ratchet and began to knot him. Ratchet cried out in pleasure, feeling the knot stretching him wide. He could feel his own overload approaching rapidly, and he knew that it wouldn't be long now. Finally, it happened. Ratchet gave a loud cry as his body convulsed in pleasure, his overload washing over him in a wave of ecstasy. Optimus followed soon after, his own orgasm hitting him like a freight train. As they lay there, panting and covered in lubricant, Ratchet couldn't help but feel grateful for Optimus's strength and dominance. He had been able to take control, driven by his rut, and he had given Ratchet everything that he wanted and needed. Optimus smiled down at Ratchet, feeling a sense of satisfaction and contentment. He knew that he had been able to satisfy his Omega, even in the midst of his rut. And he knew that he would always be there for Ratchet, whenever he needed him.
