Do Me Right

Sunstreaker triple-checked that the door to the twins' quarters was locked with a code that (supposedly) not even Red Alert could hack, and grabbed Sideswipe's little black box. No cameras. No bugs. No possible way that anyone, anywhere, could know what he was doing as long as he kept his voice down and shielded his end of the bond from his brother.

According to Sideswipe, the devices that he stored in the locked container under his bunk were supposed to make you feel sexy when you used them, or thought about using them. The prospect of shoving a molded rubber replica of a spike into his port didn't do much for Sunstreaker, but at this point it was either the dildo, or ambushing the next bot who walked by and begging to be screwed silly.

Sunstreaker didn't beg. And he sure as the Pit wasn't letting any of the slagheads in this base touch him. He'd just take care of this on his own, and then inform Sideswipe that the next time he felt like interfacing, he'd better tell Sunstreaker to avoid their quarters for a while.

And why exactly was it this incident that had Sunstreaker feeling hot and itchy and restless? Sideswipe had been in and out of berths since the twins had matured. Sunstreaker had been bombarded with his brother's sensations during interfacing a dozen times when Sideswipe forgot to shield or got carried away, and nothing had affected him like this.

His processer cheerfully yanked the memory out of the corner he'd tried to stuff it in as he crossed the room to sit on his berth. He'd walked into the twins' quarters after patrol ended, and been greeted by the sight of Mirage trussed up in a variety of straps, moaning and gasping while Sideswipe thrust into him. Sunstreaker had frozen for a second and then bolted outside and spent a couple of hours making the local Highway Patrol officers' lives a living hell. Sideswipe hadn't even noticed his brother had walked in, so all Sunstreaker had to do was forget anything had happened.

Except he couldn't forget. Sunstreaker kept seeing the slow roll of Sideswipe's hips, the way the straps held Mirage's legs apart. The thought of it sent a shudder through him, and one hand slid down to press against the panel between his legs, fumbling with the catch and sliding it open. His port was already lubricated, and he slid the dildo in, gasping as it brushed against sensors. He thrust it in and out, and then yanked it out, glaring.

The damn thing wasn't big enough. He had to keep twisting his wrist to get it to stimulate the walls of his port. Sunstreaker pitched the stupid thing across the room, and dug back into his brother's toybox.

The next dildo was bigger, stretching him wide. Sunstreaker lay back on the berth and arched his back, groaning at the pressure. Primus, it felt so good, delicious jolts of energy streaking through his body, building and building. He was so close to overload, just a little more...

As the first spasms started, Sunstreaker's hands shot up over his head to grab the edge of the berth. For a moment, he had to choke back a scream of pleasure, and then the waves of the incipient overload, instead of crashing over him, began to recede.

"Wha-" Sunstreaker shot upright, and then moaned as the movement jarred the dildo in his port. Right. Dildo moves, overload. Dildo stops, no overload. He'd just have to make sure to keep his hand moving.

Three tries later, he flopped back, cooling fans screaming. He couldn't help it; at the moment he needed the thrusting of the dildo the most, his hands let go and started grabbing for something sturdy to clench. He'd tried using either hand alone, and in desperation, both hands together. This wasn't working.

Sunstreaker ransacked the toybox, but unfortunately Sideswipe seemed to have every toy in the known universe except a self-propelled dildo. Between his legs, his port ached, and he eased a finger inside, thrusting his hips gently.

Then he flung himself back onto his berth, on his knees this time. Spreading his legs wide, he shoved the dildo in, nearly sobbing at the sensation. He was on the brink almost instantly, and he planted the end of the dildo against the berth and curled his fingers over the edge in front of him. His hips worked wildly, overload shivering up his spine, he threw back his head-

And the dildo slipped, sliding from his port and falling onto the floor, taking the overload with it.

Sunstreaker forgot that he was being quiet and discreet and tried to put his fist through the wall.

Behind him, the door hissed open. "Hey, Sunny, what'd the wall do to you?" Sideswipe asked. Then he got a good look at the room, and the grin disappeared. "Um, why does it look like a sex shop exploded in here?"

"Because you're an idiot," Sunstreaker rasped, body quivering. He didn't bother turning around. He didn't know if he could, at this point. His port spasmed, and without thinking he reached down, fingers rubbing the rim, trying to ease the need. Even that light touch made him jerk, and a whimper escaped his throat before he could stop it.

Footsteps crossed the room, and a hand on the back of his neck pressed him down, forehead against the berth. Sunstreaker opened his mouth to ask his brother just what in the Pit he thought he was doing, and at that moment the dildo thrust in hard, making him shriek. Sensation washed over him, making him keen with need, and this time it built and built and Sunstreaker overloaded so hard he offlined.

When he turned his optics back on, he was on his back. Languidly he lifted his head, looking for Sideswipe, only to find him sitting on the berth framed by Sunstreaker's legs, which were currently spread and suspended in the air, chained by means of padded straps to the ceiling. His wrists had been bound over his head and chained to the floor.

"Exactly how long have you been holding this in?" Sideswipe asked, an oddly serious look on his face.

Sunstreaker shrugged as best he could. "Since you dragged Mirage in here."

Sideswipe stared. "That was months ago. You've been driving yourself insane like this for months?"

"No, I've been driving myself insane like this for an hour or so. Before that I ignored it."

Sideswiped sighed and rubbed a hand over his face. "And I don't suppose it ever occured to you to open your mouth and say, 'Sides, I'm horny. Please tie me up?'"

Now it was Sunstreaker's turn to stare. "Why would I ask you to tie me up, you crazy fragger?"

Sideswipe grinned. "Oh, I don't know. Just a hunch I had. You don't seem to be too bothered by it right now." Fingers stroked slowly down Sunstreaker's inner thighs, detoured around the still-open panel, and curved around his hips. "Do you like this? Not being able to move, open to anything I want to do to you?"

Sunstreaker's systems stuttered as Sideswipe bent down, licking carefully around the rim of his port. Sunstreaker tried to angle his hips, to force Sideswipe to put his mouth directly on the sensitive part he was teasing, and whined in frustration when he failed.

"Now," Sideswipe said, sitting back up and unlatching his panel, "what are you going to do the next time you want an overload?"

"Go to the Pit, you smug bastard," Sunstreaker snarled, trying not to pant.

"Oops, wrong answer," and Sideswipe leaned forward, pressing just the tip of his spike in, letting Sunstreaker feel it before withdrawing again. "Wanna try again, Sunny?"

"Ask you, I'll ask you!"

Thick blunt pressure invaded him, stretching his walls, hot and alive and a thousand times better than that slagging dildo. "There's the right answer. I think that deserves a reward, don't you?"

Sunstreaker was too busy moaning to answer. Sideswipe wasn't teasing anymore; he kept up a steady rhythm, deep thrusts that sent crackles of electricity clear up to Sunstreaker's spark. And he'd never admit it to the fragger, but being tied up, arms held tightly above his head, legs forced wide, was making him frantic.

Above him, Sideswipe groaned, and that was the expression that had haunted him more than anything else he'd seen months before, that look of pure need. That look was for him, and it sent Sunstreaker hurtling into overload, body spasming helplessly as Sideswipe arched and cried out and followed him.

Afterward, Sideswipe unbuckled his straps but made no move to cross over to his own berth. Instead, he curled up beside Sunstreaker, who tried to muster the energy to put an arm around him. He failed, and Sideswipe sniggered as he flopped an arm across Sunstreaker's chest.

"Bet you Mirage and Hound got an earful. They moved into the empty quarters next door a week ago."
