The first transformation always hurt.

Your body moved in ways it simply wasn't meant to, limbs and other features twisting, stretching and warping beyond recognition. Your teeth grey long, thick, and wickedly sharp, and all of your senses heightened to best track your prey. Vicious claws ripped through the metal protecting your digits and curled around like a scythe.

Memories blurred and became hard to access. With time, they became clearer and with practice never forgotten. It was easy to tell a newborn from a mature adult – the newborns were wild, killing everything that dare breathe in their presence while the mature adults deviously stalked, calm and collected, after their next meal.

It was getting late. Very late, in fact, No mech in their right mind would be out knowing what lived in the woods, only the stupid.

Prowl was far from stupid.

He was just a little bit lost.

He had never been into this part of the forest before. Silently cursing his brother for tricking him into leaving the track and going into the thick undergrowth, thorns of the brambles scraping against his mesh and tearing the red fabric coat he'd been given to stay warm, he pulled aforementioned coat closer to him as he tried to find a clearing.

There was a rustling sound behind him, and Prowl elected to ignore it. It was probably an animal, like the last time. When it happened again, however, Prowl turned around.

He could see a pair of ears sticking up from the bramble, and what looked like a tail a little to the side of them. There was a rustle again and Prowl realized that the animal was most likely stuck.

Carefully moving towards it, he knelt down and began shifting the vines to get a better look at the ani-

It wasn't an animal.

A big, wide golden visor stared right back at him.

Well, it wouldn't do to leave him there. Besides, he could really do with some directions. Maybe this mech knew the way out?

Prowl took an energon blade out of his subspace, trying to ignore the way the mech flinched and tried to shuffle away, before cutting through the plant and freeing the mech. Once they realized that they could move again, they sat up and stretched with a quiet mewl. Prowl found himself averting his optics.

"Thanks" The mech purred, planting his hands either side of Prowls thighs and leaning towards him. "How am I ever to repay such kindness..?"

The suggestive way the mech wiggled his hips and rubbed his tail up and down his thigh had Prowl coughing awkwardly and looking away again.

"I strayed from the path and cannot find it again. Do you think you could help?"

"You've strayed a long way from it." The mech frowned, actions pausing for a moment. "You wont be getting back there any time soon, you're closer to the edge of the forest."

Well so much for visiting his grandcarrier. No more shortcuts endorsed by Smokescreen, Prowl promptly decided.

In a moment of cloud break, the moon illuminated the pair and Prowl got a good opticful of the sharp fangs that filled the mechs mouth, and he was immediately enthralled with them. He reached forwards, cupping the stranger's cheek, and used his thumb to carefully push their lip up to get a better view.

Big.

Sharp.

Tantalizing.

"You have very big teeth."

"Not the only thing about me that's big." He cheekily replied with a wink. Prowl decided to ignore it, wriggling away and standing up.

"I'd like it if you could show me the way."

Pouting at the mech, the stranger also pushed themselves up. "Ain't ya even gunna tell meh ya name?"

Prowl couldn't believe that he'd forgotten. "My apologies, my name is Prowl."

"Name's Jazz, and I promise I don't bite." Jazz replied, murmuring "too hard" under his breath. Prowl nodded, pretending he hadn't heard the last part.

They were silent as Jazz took the lead, the slightly shorter mech sauntering through the bramble with practiced ease. Prowl was having a bit more difficulty, not used to walking through the thick and thorny vines, but soon they came to an area that was dominated by tall metallic trees where the bramble didn't grow.

Once the awkwardness had left, the two were easily conversing, the conversation going this way and that. Neither realized that they had come to the edge of the forest until Jazz suddenly leapt back, hissing in pain.

"What's wrong?" Prowl asked, rushing forwards to inspect Jazz's hand, which was smoking and slightly singed.

"Edge of the forest. Ah can't go any further." Jazz replied, sticking a singed finger into his mouth to lick it. Prowl felt a throb of heat between his legs but he couldn't bring himself to tear his optics away.

The visored mech glanced at him and gave him a lecherous smirk, immediately knowing what he was doing to Prowl. Perfect. Maybe this time he could seduce the mech?

He repeated the same for all of his fingers on his hand, even the one that wasn't singed at all, before placing it on Prowls chest and pushing him away from the edge of the forest. It wouldn't do to accidentally brush against it – what a terrible mood killer that would be. While he may not be able to pass through due to his… condition, Prowl could, and he wasn't about to pass up an opportunity that had so nicely presented itself.

"What's wrong Prowler?" Jazz purred, slinking closer and pressing into him. He was inwardly delighted that Prowl didn't flinch and back away. The taller mech was pleasantly warm, which contrasted greatly with their chilly late night surroundings.

Late night surroundings called for late night activities, and Jazz wasn't going to let this one go.

Prowl didn't reply immediately, instead looping his arms around Jazz's waist- hands never straying down too low – before replying. "Just thinking of a way to repay your kindness, Jazz."

Pausing a moment to pretend to think, coupled with a hum of contemplation, Jazz smiled. "Ah have an idea." He replied, suggestively rubbing his inner thigh against one of Prowls outer, engine purring. The small hitch in Prowls breath told him that he'd won and that he was going to get exactly what he wanted from when he'd first seen the mech enter the forest with that annoying brother of his. Yes, tonight would be most enjoyable.

Prowl appeared to approve of the idea as the next moment he had captured Jazz's lips with is own, being mindful of the razor sharp teeth that were behind them.

Neither knew what had happened next, as they suddenly found themselves on the forests floor, entangled with the other, blindly searching for hotspots while gasping and moaning into the other. The red coat that Prowl had previously been wearing had been strewn away, now hanging from a nearby tree. They could get it back later, there were more pressing matters to attend to.

Jazz released a low, wanton moan as Prowl nibbled and sucked on his throat cabling, driving him into a frenzy. He wanted the mech and he wanted him now. Tightening his legs around the others hips, he tugged the mech closer so that their hips ground together. Transferring thick streaks of paint onto the other.

Prowls doorwings fluttered and the mech quietly moaned, not wanting to attract any attention to themselves. Who knew who could go on a nighttime walk around the forest? Anyone could see them.

And that chance, no matter how small, made it all the more thrilling.

Getting tired of waiting and just wanting Prowl to get the pit on with it, Jazz quickly reversed their positions with the speed only the changed would have and continued to insistently grind down on the mech's panel.

The cold night air prickled his back cooling him down somewhat, but it was no match to the blazing inferno inside him, or more specifically, in between his legs.

If only Prowl would get the damn message!

It seemed he did, however, when his hands came to rest on his thighs and he slid a nimble digit under his hip plating, hooking it around for the manual override for his panel. Cheeky bugger.

Jazz watched as Prowl's optics darkened when lubricants dribbled down his thighs and dripped onto the searing hot metal below, a low hissing sound following soon after as the fluid boiled.

Prowl's finger gently slid out as his own panel opened, spike rubbing against the others aft.

They made eye contact, ice blue optics to golden yellow visor, before Jazz smirked and leaned forwards to whisper something crude in Prowl's audial and positioned himself so that the rim of his valve was teasing the tip of the others spike. He placed one hand onto Prowls chest for balance and the other he intertwined his digits with Prowls.

Before he was able to slide down that delicious length, Prowl caught his thigh and stopped him from moving.

"You will hurt yourself." He said, not allowing Jazz any downwards movement at all, even as his engine gave a distinct rumble when his optics flickered down.

"Ah like a tight fit." Jazz easily replied, ears flicking in dismissal as he tried to wriggle out of Prowls grasp.

"I don't." Prowl countered, untangling his hand from Jazz's and beginning to circle the rim with a single digit. Jazz whimpered, attempting to thrust himself down onto it, but to no avail. When Prowl felt he'd teased him enough, without warning, two digits were slowly slid inside.

And Jazz couldn't stop his moan even if he tried.

Prowl smirked to himself as he slowly began pumping the two digits, making sure to drag over every node he could. Jazz thought that it felt incredible, and was embarrassingly vocal about it, however it wasn't quite what he wanted. Enough pussyfooting, he wanted Prowl and he wanted him now.

"Keep that up Prowler and Ah'll be done before we've even started." Jazz panted, moving back against the digits.

"Good."

Prowl began to move his digits faster, bumping against sensor nodes hidden deep within his valve. Jazz couldn't help but release a breathy moan every time the sensor was stimulated, back arched.

To say he was caught by surprise with his sudden overload would be a lie, however Prowl certainly was when the valve clamped down so hard on his digits he could barely move them.

Jazz panted heavily as he slowly came down from his high, a fresh rush of lubricant trickle from his valve when Prowl removed his digits.

"Keep that up and Ah might not let ya leave." Jazz panted, taking Prowls now stained hand and guiding it to the other mech's spike, making him smear the lubricant over it. Prowl hissed, hips bucking at the sensation, however he didn't protest. Licking his lips, he removed his hand from underneath Jazz's thigh and repositioned it onto his waist as he smirked up at him. "You wouldn't get any complaints from me."

"And 'ere Ah was thinkin' ya were jus' lookin' fer a way out." Jazz teased, pressing a kiss to Prowls lips before lowering himself onto the other mech's spike, not stopping until their hips bumped together. Jazz released a satisfied sigh, wriggling his hips as Prowl bit down hard on his lip as he released a strangled sound of pleasure.

He was, quite clearly, still trying to be discreet about it.

"If anyone comes close" Jazz purred against his audial, "Ah'll know before they can even hear us."

That seemed to make Prowls mind up as he immediately nuzzled Jazz's neck cables, exhaling shakily as he began to slowly and gently roll his hips in a steady rhythm.

It was quite a stark contrast to how he'd been working his magic with those deft digits of his, however he wasn't giving Jazz much to complain about.

Prowl began to mouth at Jazz's jaw, slowly making his way up to his audial horns where he nibbled and nipped his way up before enveloping the top with his mouth and sucked briefly. This elicited a gasp from the mech above him, valve fluttering.

"Don't you dare." Prowl growled, vibrations from his voice travelling through his audial. Jazz moaned, leaning into the touch and starting to move to meet Prowls thrusts halfway.

"Couldn't stop it if Ah tried, Prowler." Jazz replied, reaching up to play with the doorwings splayed out underneath Prowl. The mech moaned before he could stop himself, arching upwards and bucking his hips.

Within moments, the two simultaneously reached overload, Jazz arching and howling into the night while Prowl took the quieter approach of snarling out Jazz's name.

"What on Cybertron took you so long? We were worried about you!"

Prowl resisted the urge to glare at his brother and simply pushed past him, ignoring him instead. Smokescreen snickered and went after him.

"Seriously though Prowl, what happened? I heard howling."

Prowl barely stopped his doorwing from twitching, knowing full well that he was the reason for said howling. "I found the edge of the forest and drove the rest of the way." He snapped, still annoyed with his sibling.

"… Where's your coat?" Smokescreen asked, noticing the distinct lack of the bright red fabric garment.

"It got stuck in some brambles, I had to leave it." Prowl quickly lied, opening a door at the end of the hall he was walking down. "Now, I'd like to get some sleep seeing as I didn't get any last night." Prowl stated, punctuating it with a glare before closing the door behind him. Smokescreen winced. Yup. Prowl was mad.

He didn't even begin to suspect that Prowl had done anything more or that he had lied.

The reality of it was that Prowl had given Jazz the red coat – he didn't look too happy with the thought of Prowl having to leave and had made him promise that he'd come back.

Prowl could still feel the phantom sensation of the mech's clawed hands on his doorwings, lightly teasing the surface of them.

Before Prowls thoughts took a more unsavory route, he was suddenly distracted by a sharp burning sensation on his left hand. Hissing in pain, Prowl jerked his hand into view just in time to see the paint bubbling on his palm. Watching in morbid fascination, Prowl saw the paint change colour to be dark blue and in a strange design he'd never seen before.

What the..?
