Shockwave liked Soundwave the most out of all the Cons because he was silent, a great listener, and there was a mutual appeal between them. He was an excellent partner and even more fun as a lover.
The cables treaded across Shockwave's frame and wrapped around his arms to keep them planted on each side of Soundwave on the berth. His spike was taunted by the valve that refused to let him gain entry just because. He tried to thrust his spike forward to the entrance but the slim mech just moved his hips to sit to the side so it would miss.
"Soundwave," he muttered in warning.
Said bot merely tilted his helm and made a vixen smiling emoji just to be funny. Of course, the spymaster wasn't going to play nice. He never did. The cables were his form of bondage, forcing anyone caught in them to a standstill or occasionally move whenever he desired.
With Shockwave stuck in doggy style unable to move, he was at the mercy of the other Decepticon below who gently cupped his chin and realigned mischievously on all fours also to have Shockwave's spike rub the outer folds from underneath. The scientist hissed at the teasing, feeling the valve drag across his length.
"You bitch," he groaned, nudging his helm closer to Soundwave's. He thought he heard the faintest chuckle in response, but all his senses were prioritized to their session.
Shockwave immediately jolted when Soundwave grabbed his highly erect member and made it edge into him. Soundwave lowered his chest to the berth and then snapped his hips back to impale himself. There it was. Despite not being able to do anything but thrust forward, Shockwave made the most of his predicament and let Soundwave have it hard for taking his time teasing him. He met Soundwave halfway with each pounding and listened to the static Soundwave's systems made.
"Tease me? You take control every time, yet you just like to be fragged like a common animal? Ironic, Soundwave, even for you."
Soundwave's cables constricted over his arms, thin servos clutching at the berth and the fine aft grinded back on Shockwave's spike eagerly. The scientist wished he could just grab those hips and plow the mech into oblivion but in his state, he could only offer so much. It seemed to be more than enough to drive Soundwave back against him like a bitch in heat.
Then two more cables came out of Soundwave's sides. Shockwave grunted as the one around his waist stopped his motions and the other snaked around his neck. He didn't like being restricted, glaring down when he felt Soundwave tease again by wiggly his hips so crass. It occurred to him just what Soundwave wanted, to drive himself into an overload on his own terms and force Shockwave to bend to his mercy of being granted release. Those cables tensed to enforce the idea.
Shockwave scoffed, "Of course you would..."
Slipping out so Shockwave's spike could barely touch the gaping opening, Soundwave suddenly mimicked him with a short reply, "...Bitch."
His spike was engulfed again by the tantalizing tightness and warmth. This time, Shockwave was unable to move forward to meet him. He growled as Soundwave sank closer to the hilt until his whole length rested inside him. He tried to make at least micromovements, but Soundwave restricted that. Like a statue, Shockwave was forced still, only his lover could use him at his leisure.
Every time Soundwave impaled himself on Shockwave, the latter had to stand there as Soundwave's sex doll. He could feel the servo of the other coaxing the purple lit valve open to take the full length easier, rubbing his outer node and letting lubricant coating the spike fall to the berth. Shockwave mumbled to himself with his rising pressure.
Soundwave stopped his motions and grinded against Shockwave's array, focusing only on antagonizing his exterior node. That made Shockwave try anything to get the mech to move again.
"Soundwave!"
He was promptly ignored and didn't like his charge beginning to dwindle. Finally, he got his wish with nonstop hard motions, each somehow more vicious than the last. So close...so close...don't dare stop, Soundwave! Shockwave blew his load into his lover, but it wasn't as strong as he liked due to the tampering. On the other hand, Soundwave made little noises with his cables flexing each thrust until he came with a full screen of static.
Shockwave was envious.
Soundwave slipped off the berth and retracted his cables to let Shockwave fall forward almost with numb limbs from being still for so long. The scientist eyed Soundwave with utter malice. The games he played were tolerable but that was just plain cruel. Well, Shockwave could be just as vicious if he wanted to be but unlike most mechs, Soundwave had to be snuck up on. He counted his moments and let Soundwave go...for now.
The next day, Shockwave was on a warpath. He didn't bother with his experiments. They weren't a priority. No, today, he was going to get some due for Soundwave's behavior. He chased down the spymaster to the database bay near the Energon storage, a remote area and perfect for some revenge.
Soundwave heard him come in, but he made sure his desires were unreadable in body language when he was briefly glanced at. He immediately shoved Soundwave forward against the console and anticipated the mech to fight back with his cables. He captured the first two and bound his arms together. When the second set rarely used shot out, Shockwave crushed them enough in warning before wrapping one cable around each of Soundwave's legs to stiffen them to stay wide open. He tied them off and leaned over the smaller Decepticon smugly.
"Let's see how you like being bound and used for my needs."
He didn't give the spymaster any leeway, not this time. They had plenty of interface before but last night ticked Shockwave off to a petty degree. He released and rubbed his spike against the curved aft of his lover to taunt him in retribution. Meanwhile, Soundwave refrained from struggling against his bonds almost like he enjoyed the irony. Sellout.
He all but demanded, "Open."
Soundwave made a purring noise used from Earth's internet and did as he was directed. Shockwave gripped the cables binding Soundwave's arms and laid claim to the valve on his own terms. The noises the other then made were amusing.
He dragged Soundwave back to meet his hips. That pretty aft looked nice flush against him where it belonged. It felt good knowing Soundwave was at his mercy at last. Soundwave's helm was laying on its side on the console with static emitting from it once more. Music to Shockwave's audials as he leaned over to make short, faster gyrations.
The database bay had company, but Shockwave refused to stop, merely glaring at the intrusion with hostility. It was a Vehicon grunt who slowly recognized his mistake. Shockwave, however, forced Soundwave up then kneeling to face the Vehicon before he was bent over and entered again.
"You, stay here," Shockwave commanded to the Vehicon. Then he said to Soundwave, "Look at him, Soundwave, and tell him how desperate you are. Tell him you don't make the rules anymore, I do. Tell him who you belong to."
Soundwave was still full of static with each messy thrust Shockwave gave him. He grinned mentally at the spymaster's submission finally, pressing on the back of the helm to stay on the floor reveling in his dominance. The Vehicon stood by but was uncomfortable. Shockwave didn't particularly care.
He hissed as he built his overload how he liked it, not the pitiful one Soundwave left him to endure. It made him content seeing Soundwave tied up and begging in his own way for Shockwave's spike. When he filled the spymaster's gestation chamber with transfluid, the overload was one of the most satisfying with a sharp grunt and sigh. He let go of Soundwave's helm with a final growl of victory.
Shockwave said amused, "Teasing me only gets you so far, Soundwave. Remember that."
The slim mech didn't reply but wiggled his hips seemingly wanting more. The Vehicon almost looked tempted to fill the role but didn't want to overstep into Shockwave's territory, as he shouldn't. As the last part of his revenge, Shockwave just let him lie there until he had need of him again.
He would frag Soundwave once he was ready. Until then, Soundwave would just have to be patient.
AN: Someone wanted Soundwave's posted so I will happily oblige. Of course, no tentacle stuff this time, only bondage.
