A/N: This is mine, Moony. I am very, very sorry for the long delay. I had the worst case of writer's block ever(And DeviantART sure didn't help). This is a request from bloodshifter, God-only-knows how long ago. Bear with me; this is my first time writing a cluster-fuck (best word ever, by the way...XD). I hope you like it.

Sideswipe/Sunstreaker/Prowl (G1)

"Three's a Crowd"

"Alright, Sunny, that's your cue!" Sideswipe whispered as soon as Ratchet had his back turned to the duo.

Sunstreaker didn't need to be told twice. Immediately, the golden twin tip-toed--with uncharacteristic stealth--up to the Medic, then very politely tapped him on the shoulder.

Ratchet turned around and realized, too late, the mistake he'd made. He didn't even get a chance to yell at the vain mech before he received a cream pie of epic proportions to the face.

Sideswipe took this distaction to his advantage--as he often did-- and snuck into the Medibot's personal quarters, snickering evilly.

"Sunstreaker, you little-" Ratchet growled, wiping chunks of pie off his face. He reached for the golden twin's neck, then thought better of it. 'Best to let Prowl deal with him.' He thought, disappointed. He longed to exact his own revenge on the twins, for all the grief they caused him, but that wasn't his place. The yellow mech merely smirked as Ratchet grabbed his arm and escorted him to Prowl's office.

Ratchet stomped back to his own room hoping to get some rest. Instead, he saw Sideswipe laying on his bed, the red mech's codpiece mysteriously missing.

--

Sunstreaker glanced at Prowl, who was sitting calmly behind his desk. "Um...Prowl?" The yellow mech asked nervously. "Why aren't you yelling at me?"

Prowl gave a rare smile. "I'm waiting for your brother." He explained patiently. As if on cue, the door opened and Sideswipe was thrown in roughly, minus his codpiece. Ratchet growled, and the red mech's most intimate piece of armor hit his head with a loud clang.

"Ow..." He muttered, glaring at the medic. He quickly picked it up and put it back with a click as Ratchet left and closed the door.

"How do you two manage to land yourselves in my office twice in one day?" Prowl asked as he stood up, his face beginning to turn an angry shade of red and his optics narrowed to slits.

"Very carefully.

" Sideswipe piped up. "Y'see-"

That was a rhetorical question! I wasn't looking for an answer!" The copcar yelled, glowering as the duo in front of him leaned back as far as they could without falling over.

"Jeeze, you don't need to yell." Sunstreaker said irratably. "You'll short out my beautiful audio sensors."

"Yes, I doneed to yell, because nothing I ever say to you gets through those thick helms of yours!" At this, the white mech stepped forward and rudely knocked on both the twin's heads.

"Jeeze, Prowl, you need to lose some stress."

Prowl rolled his optics. It had been just yesterday that he'd gotten rid of all the stress he'd had for over 4 million years. Or was it...all gone? Then he thought to when Sideswipe entered the room with no codpiece on.

CLANG

Suddenly, having the twins constantly winding up in his office didn't seem so horrbile.

"Hey," Sunstreaker started. "I know a really good way to get rid of stress." He began, seemingly able to sense the sudden change of moods on the copcar's part.

"Hmm, so do I..." Prowl began, a sultry expression on his face as he reached over to Sunstreaker and began to undress the mech as the latter did the same to him. Sideswipe took this as a cue and quickly removed all his armor, not shy about letting anybody else see his growing pole, not after walking past the entire population of the base with it hanging out. "Oohh..." Prowl crooned as Sunstreaker's long, golden rod sprung out of its prison. "And here, I thought you were compensating for something."

The vain mech shrugged. "Yeah, that's what Moonblaster said, too."

"Enough about her, though. This is all about us now." Prowl said sensually as he stroked the side of the vain mech's face.

"Ooh, Prowler, I never knew you had it in ya." Sunstreaker commented with a raised optic ridge as he went down onto his knees in front of the copcar.

Before the golden mech latched onto Prowl's rod, the latter turned around. "Sideswipe, come closer, will you?" The red twin obeyed , unsure. "What can you do?" The--normally--logical and composed Prowl asked. Sideswipe then put both hands behind his head and thrust his hips forward, causing his hard cock to slap against his stomach. Prowl raised one optic ridge, unimpressed.

"Aw, c'mon, Prowler. Gimme a chance!" The mischeivous twin insisted. He then cocked on optic ridge, an annoying habit he'd picked up from his brother. "Let me love you."

"Fine, but not without lube." Prowl consented as he stepped past Sideswipe, opened the bottom drawer of his desk and pulled out a jar of lube. He walked back over and handed the lube to Sideswipe. "Here. Go nuts." Prowl's "what-not-to-say-to-the-twins" insinct kicked in as he realized that normally, that would be a bad thing to tell the red twin to do if he wanted to keep order. This wasn't "normally", though.

Sideswipe cocked one optic ridge and gave a sexy grin. "Aye aye." With that, he unscrewed the lid and dunked two fingers into the thick, smooth substance, groaning as he coated his rod with it. He put his free hand on Prowl's back, gently bending the other mech over, who then placed his hands on the wall, locking his elbows. "Have you ever done this before?" Sideswipe asked, keeping one hand on the white mech's back while the other pumped slowly at his own cock.

Prowl let out a breathy groan. "Uh...once, a long time ago." He responded.

The red mech chuckled as a dollop of lube found it's way to Prowl's aft. "Before you met us." He paused as the cop gave a sharp gasp. "Cold?"

"You have no idea." Prowl responded as a shudder went through his chassis.

"It won't be cold for long..." The mischievous twin hinted.

Just then, Sunstreaker moved his head back, releasing Prowl's hard pole into the open. "I'd take that as a warning, Prowler." Right after he said that, Sideswipe slowly forced himself into the white mech's tight body. Both mechs moaned loudly as Sideswipe sheathed himself to the hilt and began to pull out, savouring the feeling of such a nice, tight aft on his thick cock. When just the head remained in Prowl's body, the red twin slammed himself back in, causing both Sunstreaker and Prowl to call out, but the yellow twin's cry was muffled, as the force of Sideswipe's thrust had shoved Prowl's cock back down Sunstreaker's throat.

Sunstreaker moaned as he deep throated Prowl, one hand pumping fervently at his hard, golden pole.

"You alright down there, Sunny?" The red mech asked as he gained speed, thrusting gradually faster into the copcar. The mech in question gave a muffled, "Mmhm" and shut his optics. Once he was sure that his brother was fine, Sideswipe began to pound harder into the white mech's aft, forcing his victim to squirm and shut his optics tight as his leg and aft muscles tensed up, making the hole smaller yet. Sideswipe couldn't hold back; he let out a feral scream and took his release inside Prowl.

Prowl groaned; feeling Sideswipe's thick cum ooze out of his aft took him over the edge. He let one last, long, low moan pass through his vocal processor before he forcefully shoved his cock as far down Sunstreaker's throat as it would go and let loose a torrent of cum that ran out of the golden mech's mouth and dribbled down his chin.

Sunstreaker finished not long after that, spraying his release on Prowl's chest, who then promptly collapsed, along with the red twin."Well, you know what they say," Sideswipe started.

Sunstreaker finished the sentence, wiping his mouth with the back of his hand. "Three's a crowd."
