Author's Notes: For futurecag, who always encourages me. This is, specifically, for helping me figure out how Organ Donor will end, however. Also, a one-shot. I'm not sure how much Bee/twins smut I can write without my brain melting from the hotness...

The water pressure, at one of the lowest settings, still had enough force to make the drops of water pound lightly against Bee's back. Sunny stood in front of him, gazing down, even as Bee looked up at the older man. Behind Bee, Sides leaned in, lips brushing against the back of Bee's neck, causing him to moan. Sides' breath was warm, warmer than the water...

Both Bee and Sides were on their knees, although only Bee was handcuffed, to a bar that he suspected the twins installed just for this purpose. There seemed to be no other reason for it to be in the shower. With the handcuffs looped around the bar, attached to his wrists, Bee could kneel comfortable, although it was a strain on his arms to move much.

Sunny's dark blue eyes met Bee's baby blues, even as Sunny reached out grabbing the blond hair which was matted to Bee's head, fingers clenching, forcing Bee to stay still. Not that Bee planned on moving. He took in a sharp breath, as Sides bit down gently at the nape of his neck, shivering as he the teeth lightly dug into his skin for a long couple seconds, before letting go.

Sunny nodded, as if he had been speaking to Sides, although he had said nothing out loud. Bee looked up, studying Sunny, trusting him and his twin. Sunny's free hand wrapped around his own erection, stroking a couple times. He looked as if he might say something. Instead, the hand that had been stroking dropped; the hand still in Bee's hair pulled him as close as possible.

Bee knew what Sunny wanted.

Bee groaned at the ache in his arms, although it was all part of this experience. Sunny pulled closer, and Bee moved with him, straining to move forward. Sunny tugged lightly on his hair, and Bee complied, sitting back even as Sides' hands moved down his back, cupping his ass, pulling him up gently. For now, Bee focused on Sunny, who took half a step closer if that, free hand going to Bee's shoulder, pushing him back slightly. Sides was behind him so Bee couldn't move back too much further anyway.

Sunny moved forward again, and Bee ran his tongue over his lower lip. He shivered slightly as he began to take Sunny's shaft in his mouth, tongue daring out to swirl around the shaft. It was Sunny who moaned this time even as his grip tightened on Bee's hair, and encouraged, Bee continued.

Sides shifted behind him, one hand moving, and Bee tensed for a moment, before Sunny's hand moved from the top of his head to the side of his face, stroking his cheek. Bee relaxed immediately, even as Sides slid one finger in, waiting a moment before adding another. While not hesitating at all, the three of them were taking their time; they had learned what they needed to know from the net, but no description could fully prepare them for the experience.

Sides' fingers slid back out before he shifted once again. For a moment he did nothing, at least nothing that Bee could feel, and in his current position it was impossible for him to look over his shoulder. Sunny's hand went back to Bee's hair, guiding the younger man, pulling him forward.

Bee's tongue continued to run along Sunny's shaft, as he took more of the erection in his mouth. Sides moved, pulling closer to Bee, pushing at him. Pushing back slightly, Bee stopped when Sunny's fingers clenched in his hair, a silent order to keep still. Sides pushed forward, and Bee wondered just how much the twins were working this out through their bond. "Don't move." Sunny's voice was low and hoarse. He thrust, and for the first time since this had started, Bee wished that his hands were free, that he could reach out and hold Sunny, brace himself against the older man.

"I've got you." Sides breathed it against Bee's neck, pushing slowly. Bee moaned as best he could around Sunny's shaft, although it made no sound. Sunny pulled back, and Bee breathed, knowing that he wouldn't be able to once Sunny pushed forward again.

Prowl kept his expression blank as he strode towards the room the twins shared. He knocked on the door and when there was no answer, he overrode the code that would lock others out, although he felt slightly guilty as he did so. He was using his override despite knowing there was no breach of security. Then again, Sunny had asked to use his handcuffs right before they had managed to disappear.

Prowl sighed, glancing around the room the protoforms used. Both twins were in their bunks, recharging. He stepped into the inner apartment, which was really only a bedroom, small living room, and a bathroom. The first two were empty, and Prowl had a bad feeling about the fact that he could hear the shower running.

Still, if the twins expected privacy, they had to learn how to be stealthy at least. Not stealing Prowl's property would help more, though. He pushed the door open, freezing in the doorway, growling softly. The twins had turned to look at him, while Bumblebee was slightly... incapacitated at the moment.

"Get out."

The twins glanced at each other, before they pulled away from Bee, getting out of the shower. Sides had the decency to turn off the shower before he climbed out of the tub, Sunny following him. They grabbed two towels, wrapping them around their waists. "We can explain," Sunny assured him.

"We were experimenting." Sides spoke, sounding too cheerful about the situation.

Bumblebee looked uncomfortable for a moment.

"Let him go..."

Sunny pulled out the key, unlocking the cuffs, handing them to Bee as he stood. He wrapped a towel around his waist before he handed the cuffs, and the key, to Prowl, with a sheepish smile. "I thought they asked you..."

"They did. I said no."

"Which was why we stole them," Sides explained, both twins grinning at him.

"Yeah, Prowl, don't be mad..."

Of course he was mad, but he knew it wouldn't last long. And actually punishing the twins meant...

Primus, he didn't want to talk to them about it. In fact, he paled a little at the thought. "No." He shifted his weight. "They're gone again, and I'm holding you two responsible unless you can prove otherwise."

Bee still looked contrite, while the twins...

"Experimenting... Primus..." Prowl shook his head. "You could have told me you know."

"You still would have said no." Sides pouted slightly.

"But I would have known enough to stay away until you were done."

"We'll tell you next time."

Prowl groaned. Talking to the twins, as usual, wasn't helping the situation. "Fine." Right now, it was best to agree with them, and leave as soon as possible. He turned, leaving the bathroom, leaving their room.

Experimenting...

Maybe they had the right idea, after all. Enough alcohol might actually make him black out, if this holoform acted like a human body did. There was only one way to tell.
