Megatron kept Echo either in a room or close to him at all times. He kept grabbing her chassis and her aft, tracing her hips and rubbing her thighs. She was very uncomfortable and wanted him to stop, a few times she shoved his servo away but he always pulled her close and kissed and nibbled at her neck. He thought this was turning her on and making her want him. She wasn't turned on, he was disgusting her with all the touching and kissing and biting, she wanted nothing to do with him. She felt no love for him.
One evening he had had enough of waiting for her to fall for him. He wanted her! Just being around her was enough to make him hard. He took her to his personal quarters and pinned her down to his berth. He was much heavier so she was unable to get up, she squirmed and tried fighting back but he was too strong. He ripped her mask from her face and threw it aside. He looked at her face, she was even more beautiful than he had first thought. He slammed his lips onto hers, roughly kissing and biting her lips. She kept quiet hoping he'd lose interest in her but her silence only made him angry. He pulled back and roughly removed her armor and immediately stuck a digit inside her entrance. She still refused to make a sound, she would not give in to him. He moved his digit around, feeling her before thrusting it in and out of her at a very slow pace. She began shaking and twitching a bit, it was torture. She didn't love him. She didn't love what he was doing. She shifted and tried to pull away, moving away from him. He gripped her before getting up and grabbing cuffs and cuffed her to the berth. She tried kicking him, only resulting in him grabbing one of her legs and twisting it out of place, causing her to scream with pain. "Now you cannot fight me. You are mine. We will mate until you learn to love me!" He growled and slipped two digits in her thrusting in and out at an even slower pace than before as he leaned up and kissed her roughly as she gasped from the pain racking her body. He stuck his glossa in her mouth and felt all around. Her whimpers of pain were mistook for pleasurable sounds. Then he moved down kissing and biting her body, leaving all kinds of bite marks everywhere he could. When he got down in between her legs he spears them farther out so he had more room. He kissed her entrance then stuck his glossa in, licking all around. He tongued her deeper and deeper, reaching any spot he could. Her body was reacting against her will, shivering and shuddering, groaning and moaning. She was crying. He was raping her and she could do nothing to defend herself against him. She cummed on his face and the berth, he pulled back and licked up the mess and looked at her "Cumming already? Well we'll just had to mess around until I do." She looked at him with teary optics and whimpering softly. He removed his cover for his cable, he was very hard and slight precum from the sight, and sounds, of her. He was a lot larger than her but he didn't care about the small details and crawled on top of her, slamming deep inside her. She screamed in pain, more tears falling. She panted heavily and shifted but couldn't, he was too heavy. He kissed her cheeks before making out with her as roughly as he possibly could, biting her lower lip as he began a fast pace. She whimpered out, begging in her mind over and over for this to stop! He bit at her neck and chest, kissing and sucking  her breasts. He was riding her very hard and showed no signs of stopping. Eventually he pulled out and then turned her over, fixing her cuffs so it would hurt her arms or be in a weird position before entering her again and slamming hard inside her. She cried out louder and louder with pain. It was too much! She came again but he didn't stop. He slammed harder for a few more minutes before pulling out of her and licking up the mess again before he turned her around and she had to face his cable. She was confused. She hated him and decided to move away when he gripped her helm and pulled her back over, forcing opening her mouth and shoving his cable in, she nearly choked. He told her what she was supposed to do and she cringed, like hell she was doing that! She tried to move away but he held her in place, she had no choice but to do it. So she did as he asked, against her will, moving her mouth back to the tip and then back to the base. She did this twice before he began helping her to move faster, not liking her slow pace. He groaned and moaned louder "Oh Echo~!" He didn't cum fully but he did squirt some cum into her mouth which she had to swallow since his cable was still in her mouth.
She wanted to die.
When he got tired of just a blowjob he then did something she never heard of. He laid down underneath her, after removing his cable from her mouth but it was still close to her face, which she looked away from. He placed her legs on either side of his helm, she winced at the pain in her dislocated leg being moved, he then told her to suck his cable again. She, still not having a choice, did as told. He stuck his glossa inside her again and began tongue fucking her once more, he reached deep into her for her spot as she continued doing what he demanded, moaning and groaning. She came again on his face but he kept going. She pulled her mouth off of his cable for air and panted heavily, her whole body shaking. He pulled his glossa out of her and once more licked up the mess she made before turned her back to where her face was close to his and slammed his cable inside her again. She arched her back this time and screamed out. He licked and sucked her breasts, he just couldn't get enough of her.
Eventually he finally came inside of her and pulled out panting. Echo barely had enough energy to even move. He kissed her again and laid her down "We will continue until your sparked with my young." She was silent. Megatron put his cover back on and went to the washracks, comming Knockout to go to his personal quarters and clean up Echo and the mess they had made. When the door closed Echo fully broke down. Her body was racked with all kinds of pain and she was exhausted, so much so she was asleep by the time Knockout had arrived to give her a bath. He felt sorry for her as soon as he saw the state Megatron left the poor femme in. He needed a way to get her out of here and away from that brute who calls himself their leader.
