Description - Smokescreen and Bumblebee want to welcome Knockout to team Prime their way.

⚠️ Warning!: Contains Threesome boy x boy smut ⚠️

After the Decepticons were clearly on the loosing side, Knockout took the initiative to switch sides without question and join the Autobots. Optimus, being the leader that he is, didn't object. Arcee, Bulkhead, Ultra Magnus, even Ratchet learned to accept the Decepticon into their team. But the others were having more trouble trusting him at all, especially Bumblebee who had been foiled by him many times. Knockout understood the scouts reasons, but he wanted to prove to him and Smokescreen that he wasn't playing them for a fool.

Bumblebee and Smokescreen were busy lobbing in Bee's room as Ratchet couldn't tolerate their rough housing around his precious equipment, not after they snapped one of his welders in half. Knockout peered in to see the two going at it. Smokescreen was being competitive and used all his strength and lunge the ball of scrap metal at his buddy. Bumblebee caught it with a struggling grunt, sliding back a couple of feet from the impact. Smokescreen laughed in amusement.

"Nice one Bee! I thought that one would knock you over for sure!", he flashed him a wide grin.

"I'm stronger than I look", Bubblebee smiled back. Knockout walked in clearing his throat to avert their attention from their session. The two turned their helms to the red mech, wiping the smiles off their faces.

"Hello Smokescreen", he greeted and turned to the scout. "Bumblebee". Bumblebee had an impulse and the corner of his derma perked up.

"You come here to play? Here, catch", he asked before tossing the ball his way. Knockout's optics shot open and he shrieked, ducking out of the way cowardly as the chunk of metal flew right over his helm. It smashed against the wall, leaving a cracked imprint before falling to the ground. The startled mech turned behind him and then glared at Bee. He was only given an innocent smile.

"Very funny Bumblebee, but I don't associate with extreme sports that would risk scratching up my looks", he said as he brushed off his shoulder plates and approached the two.

"What do you want?", Bumblebee asked rather rudely before Smokescreen as he was thinking the same.

"I just want to get to know my team a little better that's all", he gestured to his new team members. Bumblebee despised the mech, but he couldn't help but stare at his flawless design. Knockout was such an attractive bot, it was a shame he had to bust his metal whenever he encountered him in battle. He hated the fact that something so pretty would be on the bad team. Even now that he is with Team Prime he has his doubts on accepting his interest with him.

Knockout watched the scout intently who was standing idled without a word. He rolled his optics in irritation.

"Come on guys, what's an ex Decepticon gotta do to get a proper welcome? I"ll do anything". Smokescreen looked at Bumblebee with perverted grin. He wasn't sure how Bee felt about it, but the blue mech secretly wanted to punish the medic for tinkering with his insides way back when he snuffed out one of the Omega keys out of his gearbox.

Smokescreen made his way over to Knockout and placed his servos on his hips, leaning into his personal space in attempt to make the mech uncomfortable.

"Anything eh?", he looked at him deviously. Knockout sunk his helm in from his close presence. Smokescreen went behind him and started pushing him towards Bumblebee who was wondering what his friend was up to. Knockout reluctantly allowed himself to be guided over to him.

"Alright then, what do you say we do with the pretty boy?", he glanced at the scout. Bumblebee blinked at him. Smokescreen knew the scout had a mini crush on the medic. It was a tempting notion. Smokescreen was basically giving him a look that said go for it.

Knockout flinched when he felt Smokescreen's servo glide onto his hip from behind. He looked over his shoulder to the mech who was touching him, processing his action. Bee saw his friend pulling moves already. It made his chassis swell up just thinking about taking advantage of the new recruit. He couldn't hold back anymore. He walked towards the medic and forced a kiss onto him. Knockout accepted it as if he knew what was about to happen. He moaned into the scout's mouth when Smokescreen pulled himself closer behind him, kissing along his shoulder. Knockout pulled away from the kiss that was laid upon him.

"Alright, you want me to play your game? Fine..", Knockout gave in. He grabbed the scout's face in his servos and pulled him back to his mouth, forcing his glossa in. Bumblebee's door panels bounced and he unwillingly aloud him to invade his cavity. He whined from the slick wet glossa snaking inside him. He was already unmatched by his experience. Smokescreen was busy working along Knockout's neck cables. The hot breath of the mech against his vulnerable area was making the medic shiver. It was distracting him from his duties with Bumblebee. Curse these mechs for getting him this turned on.

Smokescreen was nipping along the wires seeking the one that made Knockout squirm. He bit a little too hard on one of them and Knockout hissed, turning to push the mech behind him down. They both fell over with Knockout on top. The medic growled at the bot pinned beneath him for teasing him. He wanted to punish him for the way he was grinding against him earlier. The horny medic turned to look at Bumblebee who was watching his friend being held down to the ground.

"If you guys want to frag me so bad why don't you do it!", he snapped at him. Smokescreen chuckled.

"That's just what we were planning, right Bee?", he cocked an optic ridge over to him. Bumblebee stared at Knockout with lust filling his processor.

"Yes..", he spoke softly like something inside of him was forcing him to continue. Bumblebee grabbed onto Knockout's aft, earning a startling grunt. The medic turned to see the scout's spike was already out and ready to penetrate him. The way it was presented made him weak minded. He wanted it deep inside of him. His own throbbing erection was exposed to the two mechs. He wasn't ashamed of his vulnerability if it meant he was going to get something out of it.

Knockout gasped by his spike being grabbed by the mech underneath him. Smokescreen started stroking it slowly, looking back up at him greedily. Once his own spike came out he held it against Knockout's own length and rubbed them together. Knockout moaned in pleasure. The feel of their spikes gliding along each other was enough to make him loose his bolts. Smokescreen placed his other servo along the side of Knockout's leg, stroking the smooth metal. He could just see the blush on the medic's pale face forming. It was almost adorable. Bumblebee's face blushed from the sight of Knockout being pleased in such a way. It made his spike ache even more to be inside his crush. Everything inside him was screaming for him to follow his urges. The energon on his body was rushing down towards his sensitive organ. He finally positioned his member against Knockout's entrance and pushed in as carefully as he could so that he wouldn't hurt the medic as much.

"Ahh! Slaggit Bumblebee!", he screamed from the intrusion. He was already panting from the friction between him and the mech rubbing against him. The pleasant sensation coming from his groin and the pain from Bee sinking himself into him was overwhelming.

"Nnn...ahh...s-so tight", Bumblebee commented in a trance. The feeling of Knockout's hot insides hugging around his spike was too much. It was everything he ever wanted from the medic. With his servos, he pulled Knockout into him. The movement was helping out on Smokescreen's end. He pushed himself forward against Knockout's spike enjoying the feeling.

"Mmm, you must really want our approval of your addition to the team Knockout", he teased. Knockout closed his optics, taking in Bumblebee's full length in his afterburner. Smokescreen rolled his optics back, jerking from the waves of pleasure shooting from his spike. He hit his helm against the ground, breathing heavily. He was enjoying the view of Knockout's expression.

"Is...mmph...is that all you got scout?", Knockout moaned. Bumblebee bucked his hips once into him aggressively causing the medic to gasp. He couldn't stand his tolerance with the two of them messing with his circuts. He wanted to make him whine for more. He refused to change his rhythm. Knockout turned to Bumblebee although he couldn't fully look at him with his position. His ignorance was making him aggravated.

"Bee....please", he urged him to move faster, but he didn't respond. The slow pace was driving him nuts. It wasn't enough for him. He moved his own body against the scout. By this time he figured he was doing it on purpose.

"Come on Bee! Don't you want to slam into my port with everything you got? I can take you", he wiggled his aft. That was the last straw. Knockout was getting to Bumblebee's helm. His digits digged into the medic's thighs and he increased the speed. Knockout rewarded him with an overly excited moan, instantly melting into the new change of pace.

"Oh frag Bee...yes!", he yelled. Bumblebee grunted with each of his thrusts. He knew there was no going back if he continued to dig deeper into the mech's sweet aft. Smokescreen matched up the movements. He stroked part of Knockout's spike while he grinded against the other.

"Don't steal all the glory Bee", he laughed. Smokescreen pulled his helm off the ground and licked along Knockout's chest plate. He was aiming for his headlights that signified the sensitive points of his chassis. The medic's body reacted to the touch of his glossa wonderfully.

"Oh Smokescreen", he moaned the mech's name. That's just what the rookie mech wanted to hear.

"That's right KO, who's the rookie now?", Smokescreen mocked.

"M..me", the medic replied trying to hold back all the moans escaping his throat.

Knockout was in heaven. His face was just as red as his finish. The pleasure he was getting from the front of his body made Bumblebee's spike feel even better. His body shook uncontrollably from the head of his spike hitting deep inside of him and everything Smokescreen was doing. They were both battling to give the red mech the most pleasure. Knockout was worried his body was going to fall apart. His body was sweating, his sparkbeat was practically beating out of his chassis, and he felt like he wasn't getting any air into his vents. His body was so hot from the action and the surrounding body heat. He felt like he was going to burn to death if his overload didn't come first. Luckily he could feel it approaching.

He focused on all the feelings building up inside of him. His finish hit him like an explosion. He screamed out from the intensity of it, spilling his fluids onto Smokescreen's chassis. His sensor nodes sparked and everything in his processor went blank. It's like everything in his vision went white. The feeling was nothing he had ever experienced. He could feel his fatigued body giving out afterwards. Smokescreen finished around the same time, dirtying up his plates in hot trans fluid.

Bumblebee was still ramming into Knockout in attempt to catch up to the others. All the plates in his body seized up. He arched his whole body back and pushed forward one last time to shoot his trans fluid inside of Knockout. The medic groaned from the wet liquids filling his innards. Smokescreen allowed the mech on top of him to fall against him. Bumblebee stood with his legs shaking, struggling to hold up his weight. He was breathing profoundly cooling off his body. Knockout was having the most trouble catching his breath with his body being too overheated. He turned his helm to the side.

"Wow Bee, you interface like you fight, you pack a punch", he grinned. "I feel like you were enjoying that more than me. I bet you wanted this to happen". Bumblebee blushed at his perfect guess. He was able to see right through him. He turned his helm away to hide his flustered face.

Smokescreen chuckled softly.

"Welcome to Team Prime Knockout".
