AN: For tiamat1972, on LJ, who requested Horny, Ratchet, and Optimus Prime. This is why I should not write at 4am when insomnia is acting up. Many thanks to okamimyrrhibis, my wounderful and amazing beta.

SN: Yes more SLASH, and it is a more explicit then anything I've written before. It is definitely rated M. Consider yourself warned. Although technically G1, I keep seeing Prime in his movie form...

Horny

He hadn't meant to spy on them. He really hadn't. He'd just gone to the medbay for a checkup; something in his transformation sequence had been feeling off lately. Ratchet hadn't been there, but he never left the medbay for long. Resolving to wait for the medic, Bluestreak had sat upon one of the repair tables, mentally going over his schedule for the next couple of days. He hummed quietly to himself, a habit very few knew about.

Nearly a breem had passed, and Bluestreak was just starting to think he'd have better luck coming back later, when the doors to the medbay slammed open. This was not unusual, and Bluestreak did not even look up. Ratchet would attend to him when he was ready.

What was unusual was the low, rumbling moan of pleasure. Bluestreak's head shot up. There standing in front of the medbay's doors was the anticipated medic. Said medic was involved in an extremely heated kiss. However it was the bot that the medic was kissing that blew the Datsun's processor. Optimus Prime. Ratchet-the-Hatchet-and-Miracle-Medic was kissing Optimus Prime-the-Hero-and-Autobot-Leader.

He shifted, telling himself it was from the embarrassment of seeing two of his role models together, when they weren't aware of him. He cleared his intakes hoping they'd notice. He shifted again, as he noticed the medic's hand snake between their bodies, and the semi groaned. Slag it, he couldn't lie to himself. He was most definitely affected by the erotic site, despite the bots being vorns older than himself.

Impatiently, never breaking the kiss, the medic led the way to his office. Just before the door closed Ratchet broke the kiss to moan and over his head Bluestreak's optics met Prime's. With a wink, the door closed, cutting off the stare. The gunner leaped to his feet, hastily leaving the medbay in search of his own lovers.

The twins had been alone in the rec room when Bluestreak rushed in. One look at his flush face and the two were on their feet beside him. Before they could get a word out, Bluestreak yanked his golden lover into a desperate kiss. Hesitantly Sunstreaker's arms came up to hold the younger mech. He pulled back slightly. "I want you," he murmured. "Please." Before the sun-kissed twin could respond, the gunner twisted in his arms, and pulled the crimson twin into an equally hungry kiss. "Need you," he panted, as the kiss ended.

Sideswipe leaned down and kissed the gray mech, hard. "Not here," Sunstreaker growled in his audio. A shiver ran through the body he held in his arms.

"Our quarters?" The scarlet mech's voice was a sultry purr.

In response the golden Lamborghini hoisted their lover into his arms and strode out of the rec room. Thankfully they met no one in the halls. As they paused to let Sideswipe enter the code, Bluestreak began to impatiently plunder the mouth of his lover; Suntreaker did not let him remain dominant for long. Whimpering in pleasure, Bluestreak gave up any pretenses of control. He was vaguely aware of Sunstreaker entering the room, and laying him across their berth. He was aware of the golden Lamborghini's mouth as it began to move down his body, and he was very aware of when the red twin's mouth joined his brother's.

The air was silent except for the buzz of cooling fans, the panting of intakes, and gasps of pleasure. Bodies entwined, heat searing along panels. Hands glided across sensitive circuits. Mouths followed, tracing the same path. Bluestreak could only lie back allowing his twins to take control. His intakes hitched when Sunstreaker yanked his brother up for kiss hot enough to scorch. Uncaringly the Lamborghini's devoured each other, even as their hands continued to drive the Datsun to greater heights of pleasure. The two parted for a moment, and a slight whimper of disappointment escaped their lover. Surprised the twins looked at the mech beneath them. Then with a sly grin Sideswipe drew his brother back to him. If the other kiss was hot enough to scorch, this one easily melted. The sight inflamed Bluestreak. With an uncontrolled moan, he teetered on a knife's blade before plunging into raging pleasure. The energy of his fall dragged his lovers with him.

Bluestreak could not find the energy to track the time as they lay entwined, bodies slowly cooling. "Mmmm" one of his lovers hummed in satisfaction. Silence permeated for a while, before Sideswipe managed to push himself up enough for a chaste kiss. "So what brought this on?"

Bluestreak felt his body beginning to heat again, as he recalled the scene in the medbay. Instead of answering he pulled the red twin in for a deeper kiss. Maybe he'd tell them later.
