So there Ratchet lay on First Aid's berth, stuffed from a huge meal and running hot. The click of the interface panel sliding open was music to Aid's ears and once more, a cheeky grin was worn. The little mech rubbed his fingers over the other's sheath in small circles, but not much encouragement was needed to coax the spike out. Once it did, Aid palmed it and giggled.

"Wow, you are such a big boy, aren'tchya? First Aid said and started to pump his hand around the erect spike. Ratchet just blushed and gave a little moan as he watched Aid slide down to bring his lips to the head- at least the best he could with his belly blocking the view. The moist lips rubbing themselves against his spike's head could be felt, and with a lusty sigh, Ratchet settled for closing his optics and enjoying the sensations he felt.

With the use of his tongue, the spike was licked as if it were an energon pop before Aid captured it in his mouth. He began to suck on it and hum. The vibrations that gave felt amazing! Ratchet couldn't help but buck his hips some, shoving his cock deeper within the other mech's mouth. Aid took the hint, and began sliding his mouth up to the tip and down to as far as he could take it. His tongue traced circles around the shaft as he bobbed his head up and down.

While sucking the older medic's spike, First Aid slid a hand down to play with himself. Servos brushed past his spike and found the valve, which was already moist. He started with rubbing circles over the port, his fingers knowing exactly what he liked. One digit slipped itself in and found the first back node, causing him to shutter and let out a moan. A second finger was added and it explored up the front until that one found a node as well. First Aid was in heaven! His cooling fans where churning out hot air as he brought pleasure to both Ratchet and himself.

"Mmmmm... Aid..." Ratchet moaned. Having his spike sucked felt unbelievably good! Much better than he ever remembered, but it wasn't like he got the chance in such a long time. Not many people had found him attractive. True, growing up he was the fat mech, and being fat meant you weren't really a bot, or you where dirty or you where- the best one- not deserving of any love. But even when he was thin, it was the same. Yes, he had previous lovers, but nothing that lasted very long. He just didn't feel loved by the other mech. Ratchet let out another moan as it felt like a build of electricity was within him and he quivered a bit, feeling as if his cock was on fire. The promise of release was near and Ratchet eagerly awaited the euphoric feeling, however, First Aid stopped.

With a look of frustration, Ratchet sat up. "Aid!" Ratchet whined. "I was so close!"

"Don't worry, I'm not done with you yet." First Aid said and pinched his belly. "I want to get fucked by you."

Hearing Aid talk like that drove Ratchet nuts! He grinned fully as he watched the smaller mech climb on top of him, position himself by his hips, and took hold of his spike. He spike was teased; Aid rubbed it on his valve, smearing the leaking lubricant all over the tip and even stuck it in the slightest bit, but never fully entered. Ratchet bucked his hips impatiently, but all that earned is the smaller mech to stop and laugh.

"Don't be greedy now!" Aid said lovingly as he continued to rub the cock all over his interface panel. Ratchet was growing more needy by these actions, but he simply laid his head back and took whatever Aid gave him. It was when he was least expecting it did First Aid line the spike up with his port and quickly pushed himself all the way down.

"Ah-Aid!" Ratchet moaned as his back arched at the feeling of being consumed by such a tight port. Glancing at his partner, Ratchet was concerned; Aid didn't prepare for the intrusion. Aid was much smaller than him, and while he enjoyed being gripped tightly, he didn't want it to be at the cost of the other's enjoyment. However, First Aid's engines revved and his head was thrown back. Pleased moans escaped his lips and when the smaller mech lifted his helm to look at Ratchet, there was no denying how much he loved being filled so tightly.

Slowly, Aid began to rock his hips, causing the spike to rub against the nodes within his valve and a moan escaped his lips. The pace steadily increased and the hips began to rotate in a circular motion. "Ahh... You feel s-so good inside *ah* of me!" Aid cried out in a lust tone.

Ratchet grinned. If First Aid felt that good now, he hasn't felt anything yet! When those hips pushed themselves down, Ratchet began to thrust his hips up into them. The action buried his spike deep within his partner's; it brought stars to Ratchet's eyes, and it must have done more for Aid. Primus he was lucky the other mech's where out on a mission or else First Aid's screams would have woken up everyone on the ship! Aid leaned forward, placed his hands on the chubby belly for support, and took in the pleasure sent to him.

Once again, First Aid pulled himself off of Ratchet's needy spike, eliciting another whine from the mech on bottom. Aid laid across the red and white mech as he panted to catch his breath. Even though he was rather frustrated, Ratchet wrapped his arms around the smaller bot, rubbing his hands and kissing his helm in a soothing gesture.

"You OK Aid?" Ratchet asked.

"Hmmm..." First Aid replied. "I feel amazing!" He lifted his helm to look into the other's optics.

"Why did you stop?" Ratchet questioned.

"I want to do one more position, then we can loose ourselves." Aid replied and rolled off the other. He mentioned for Ratchet to get up, and when he did, Aid took to laying on his back on the berth. He propped a pillow under his aft and spread his legs as an invitation for the other.

Of course, Ratchet eagerly took that invite. He crawled over to his partner and rubbed his fingers over the slick port. Next, it was his turn to tease. A finger would insert just enough to brush a node, and Aid would want more, but he never gave it to him. After several near- touches, Aid was squirming his hips and panting, his eyes begging for more. Ratchet lewdly smiled and shrugged his shoulders. Sucks, doesn't it? But he didn't have the spark to keep it up, and soon spread his legs some to position their interface panels together.

Once lined up, Ratchet pushed his spike inside and let out a moan. He thrust forwards slowly until he was all the way in and huffed out a sigh. First Aid wrapped his legs around the other's waist, and with his hands, pulled Ratchet forward. "Lean over me." He spoke, and Ratchet did, but by doing so, his belly laid over the smaller bot and squished him. Ratchet didn't want to suffocate him and gave him a concerned look.

"I like being squished by your big belly." Aid said between gasps.

Ratchet just held his mouth open, not really knowing what to say. "You... First Aid, you are positively weird!" Ratchet settled with and First Aid grabbed at his pudgy belly, lifted it towards him and kneaded it with his hands. Ratchet began pumping his spike in and out of the valve with First Aid half slitting his optics at the feeling.

Unfortunately, this felt so good for Ratchet, and with not getting this kind of pleasure in a while- plus Aid's valve was just so tight and wet, he could already feel the electric sensations in his spike. He quickened his pace, now slamming himself into his assistant and muttered out an apology as he lost control and his spike spurted out trans fluids in the quivering valve. First Aid rocked his hips fiercely then groaned out his overload. The pair laid still for a moment, catching their breath and fans hitching as they rode out their afterglow.

"That was amazing!" First aid squealed as Ratchet rolled off the smaller bot and onto his back. Aid could breath easier, took a few deep breaths, and rolled over to curl himself against Ratchet. "You felt so good inside me." He wrapped an arm around Ratchet's and placed another one on his belly. He was really hoping Ratchet would stay the night with him.

"You know, I almost forgot how good that felt." Ratchet said as he threw an arm around Aid and pulled him in for a kiss. The smaller bot eagerly kissed back, swiping his tongue over the other's lips to coax them open, and then sliding it inside to explore. Ratchet let out a moan, allowing the deeper kiss and rubbed his hand over Aid's body. When the two broke apart, Aid was smiling as he snuggled into Ratchet's body.

First Aid got his wish, soon Ratchet was snoring lightly as he had fallen into recharge. Closing his optics again, Aid rested his helm on his partner's chest and sighed contently. The last thing he remembered was hearing Ratchets systems lulling him to sleep.

That is, until a loud bang that sent vibrations through the ship woke him up. He groggily sat up and wondered if he just dreamed it. Listening in the dark, his mind would play games with him. Did he hear something walking around the ship? But every time he swore he heard something, the sound would stop.

Perhaps the crew arrived back? Couldn't be, if it wasn't Rodimus himself balking loudly, it would be one of the twins. First Aid let out a nervous huff of air as he quietly placed his pedes on the ground. He'll end this mystery once and for all by simply looking out in the hallway. When he reached his room's door, he looked back at Ratchet, then decided he shouldn't wake him up- it was probably just his imagination getting the best of him. If anyone broke into the ship, a whole slew of alarms would be going off.

With a final deep breath, Aid palmed the door open, and a green mech was in the process of walking past his door, however upon the door opening, the mech turned to look. First Aid let out a startled scream as he recognized the bot to be Hook. With an attempt to protect himself- and his lover- Aid ran to his gun, cursing himself for not keeping it in his subspace as he was advised to. He didn't make it too far as the Decepticon grabbed him.

"I got one." He shouted and two more of the combiner team arrived along with Starscream and Skywarp.

Ratchet, who was now awake went for his sub-spaced gun, but by the time he pulled it out and pointed, Skywarp teleported to him and restrained him.

"Well well, look what we have here." Starscream spat. "These'll do. After all, I am sure they will be wanting their medical team back. "Take them away."

Hook picked up First Aid who did his best to struggle out of his grasp, but there was no point. The 'Con easily overpowered him and carried him out of the room. Skywarp grabbed a hold of Ratchet and simply teleported him away.

"Let's get back." Starscream said, and the remaining crew left the ship almost as quickly as they came.

Well, there you go. This will be continued on in the next series. :D
