Curl

Carly walks out to the cliff side that overlooks Serenity, California at Autobot Headquarters. With the intention of watching the sun set as she waits for her boyfriend, Sam, to return from work, she brought an old blanket to sit on and later wrap up in as the temperature inevitably drops.

A large, angular silhouette fills most of the space between two trees that are growing near the cliff side. It appears that she is not the only one with the idea to watch the sun set to pass the idle time this evening. Not wanting to break the silence, Carly continues towards the overlook without a word. She comes to stand to the left of the silent titan that is Optimus Prime. The Autobot is partly reclined, leaning on his left elbow, right leg bent up as he looks out over the valley from the gentle slope of the overlook.

A light breeze tosses her fine, dark blonde hair across her face and she brushes it back behind her ear as she picks up that scent, the scent of machinery. Diesel. Warm metal. A smell Carly has now more or less begun associating with the Autobots. But, her nose catches something else that she hasn't smelled before, and it causes her to furrow her brow in confusion while she tries to identify it. It is then that she sees a strange tube-shaped object held dexterously between his right middle and index finger. It looks like a giant version of a vape pen, a flavored liquid tobacco vaporizer that has become quite popular in recent months among the country's young adults. She sees what she assumes to be smoke curling lazily up from the far end of the device.

Just as Carly's brain starts to make the connections, Optimus lifts it to his lips and draws in a long breath, verifying her suspicions. Prime rests that arm back across his stomach and he slowly exhales.

Carly gets goose-bumps as her most deeply held secret fetish plays out before her eyes, on a massive scale. She watches the voluminous and thick cloud of smoke pour from the Autobot's mouth, and then from his nose as he closes his mouth at the last moment.

She has always entertained a certain enjoyment from watching a man smoke, she finds the behavior, all its subtleties and motions and even its effects to be quite calming and in some cases even slightly erotic. Smoking as a habit though does not sit well with her because of its side effects, at least when it comes to tobacco cigarettes and the like. But she loves to watch the man manipulate the smoke upon exhaling. And Optimus just inadvertently preformed one of the behaviors that Carly particularly loves.

The two watch the cloud of smoke rise and dissipate against the blushing sunset. The bluff is refreshingly quiet, save for the rare chirp of a cricket and the odd breeze rustling through the tree leaves, so Carly can hear Optimus breathing, or 'cycling' as she was recently informed. "We cycle air through the intake manifolds to cool the body and provide the oxygen necessary for the conversion of your diesel fuel to usable energon." That was how Ratchet, the Chief Medical Officer explained briefly to her one evening after she bombarded the somewhat grumpy old Autobot with questions regarding a wide range of things from their history to their physiology. The latter being a subject the CMO was far more eager to discuss, and did so enthusiastically when presented with questions.

Carly watches the slow rise and fall of Optimus' huge chest, enraptured for a moment by how human he seems, despite his enormity. The vibrant reds and brilliant oranges of the sunset reflect on his gleaming paint and remind Carly of the view it's a mirror of. She turns to watch the sunset paint the sky in countless shades of red and pink, orange and yellow, even purple. Her gaze slowly returns to Optimus as he unknowingly stokes the growing fire of her emotions. She hears the whisper of hydraulics in Prime's arms as he lifts the strange, vape pen-like device to his lips and takes another drag.

Optimus looks up at the flame-painted sky for a moment before he gazes slowly down at Carly. Angling his head to the side he exhales the smoke all at once in a quick puff, Carly's toes curl involuntarily, and he looks back at her. "Good evening, Carly." He rumbles softly, his pleasantly smoky baritone rouses her from her momentary awestruck stupor and she makes eye contact with the Cybertronian. She has to collect her wits for a moment to make sure she doesn't stumble over her own tongue.

"Hello, Optimus," she starts in her smart, British accent, trying now to figure out how to best ask the question that her mind is screaming at her to ask. "Are you," she pauses a little awkwardly, "ah…," a blush is starting to rise in her cheeks, "are you smoking?" She finishes through a subtle chuckle at her foolish sounding question, looking up at the huge Autobot.

Optimus turns the corner of his mouth up in a small smile, "Well, I suppose that is the best comparison, yes. I can stop, is it bothering-"

"Oh, no! No! You're fine!" Carly stops him mid-sentence, her tone reassuring. "It's just, I guess…" She battles with herself over whether or not she really wants to tell him her 'secret'. She caves with a sigh and dives in headfirst. "I guess you could say I have this, sort of, thing for smoking. Like…The movements, gestures, manipulation of the smoke, that sort of thing." She admits slowly, hesitantly, curling a lock of her hair around her finger and absently biting her bottom lip. Carly is overcome by a rush. Her mind floods with shock. How in the world was she able to just spill her secrets to him? She truly doesn't even know him all that well! And yet here she is telling him one of her biggest turn-ons!

Optimus Prime, to his credit, remains quiet for a moment, arching an optic ridge in respectfully subdued curiosity. He immediately picked up on her change in demeanor and with prudence, he treads cautiously. After a short span, he draws a breath and speaks, "You're saying that certain behaviors, movements, or actions executed by someone as they smoke," he pauses, clearly trying to find the best and most benign word to use before continuing, "excites you?" He is now genuinely and innocently inquisitive of this new hidden facet of the human psyche Carly has revealed to him.

Taking another drag, he watches Carly blush furiously and drop her gaze immediately to her feet. He holds what she will call, for simplicity's sake, the vape pen, between his lips and reaches down to her, gently lifting her face to meet his gaze with the tip of his massive index finger. He starts to exhale through his nose before he pulls the vape away to speak, "Carly," he begins, smoke curling out of his mouth as he speaks, "there's no reason to be ashamed or embarrassed about that. In fact," his voice drops a bit to a darker, more enticing tone that catches Carly off guard even more than she could have imagined, and it strikes her somewhere she is startled to acknowledge at first, "I find it particularly intriguing." His voice drops slightly lower and the husky tone rumbles in her chest as his cobalt optics narrow slightly as he explores this curious reaction. Optimus' mind is starting to slow a bit as the chemicals in the vape pen start to slowly take effect, comparable to the manner in which THC affects the human brain.

Carly's chest tightens in a sudden hot wave of…arousal? Wait, what? Where is this coming from? Why is this all of a sudden turning her on so much? Her mind is clouded; Optimus Prime just played her like a finely tuned instrument, with his soft touch and the tone of his voice coupled with the knockout punch of the smoke curling from his lips with every word. He did her in. Carly bites her lip, her expression one that Optimus recognizes quickly. Her eyes almost beg him to continue down this path and, admittedly, he is quite happy to oblige, eager to further his own immersion in this euphoria he knows he can now share with another. He doesn't know what may come of this but he sees no harm in exploration.

Carly sighs shakily with this unexpected arousal as the big Autobot reclines fully onto his back with a barely audible groan. The ground beneath Carly's feet trembles ever so slightly as the leg that Prime had bent up slides out and falls to the ground with a dull thud. Lifting the vape to his lips, Optimus takes a long gracious drag and holds it for a span.

Setting the blanket on the ground and taking a seat on it, Carly watches as his huge chest expands graciously. Her eyes follow the suddenly very human-like outline of Optimus' chest up to his neck, where subtle motion catches her eye briefly before she turns her attention to his face, specifically his mouth. His lips part and a curling cloud of vapor rises and hovers just beyond the curves of his lips for a moment before a gentle exhalation pushes the vapor out in a slowly swirling cloud. Prime's lips close and the last of the vapor trails from his nose, rising to join the first cloud as it disperses above him.

"Optimus," Carly whispers. The Autobot slowly turns his head to look at her, and as his cobalt blue optics meet her blue eyes, they begin to dilate. Optimus blinks slowly as the 'high' really starts to set in. Carly swallows hard, she has a pretty good idea of what the Cybertronian is probably feeling right now, and that thought alone works to intensify her growing desire to be closer to him.

"Yes, Carly?" Optimus' voice is soft and low and he raises an inquiring optic ridge.

"Do you mind if I get a little closer to you?" She chews on her lower lip and her hands work the bottom hem of the light, white denim jacket she is wearing anxiously.

Optimus' optics immediately soften to an obliging gaze, "Not at all. Here," he replies, reaching over to her with his left hand, palm upturned as an invitation, "climb on. I'll sit you on my chest."

Carly stands and walks over to the enormous hand and her right hand grips his thumb as she hesitates. "You sure-"

"No, please. I insist." Prime interjects gently, urging her onto his waiting palm. Tenderly wrapping his fingers close around her, he lifts her to his chest where he helps her climb down to sit comfortably between his chest plates, atop his sternal shielding. Carly settles in, takes off her flats and tosses them to the ground and crosses her legs.

Beneath her, Optimus shifts, raising his left arm to rest his head on it. Instinctively, Carly's hands slap down to steady herself and she jumps a little as Optimus speaks, his voice rumbling against her bum and hands, "Comfortable?"

Carly slides her hands across the very smooth metal beneath her as she notices the warmth emanating from it, like a car's hood after a long drive. And then she notices a very subtle and slow vibration beneath her palms. A little stumped she hesitates, "Yes," she starts, pausing as her brain tries to comprehend what her hands are telling it. "You're quite warm…" another pause as the steady vibrations continue at very regular intervals. "Optimus, what exactly am I feeling right now?" she asks timidly.

Optimus lifts his head just enough to make eye contact with her and blinks slowly, "Your hands are quite possibly detecting the rhythmic vibrational dynamics between the spark core module and the energized plasmic aura that encases it."

Carly's whole body slumps a bit as Optimus' words sail right over her head and she makes an utterly confused expression, blinking slowly as if to clear her vision. "What?" she quips softly.

Optimus' optic ridges furrow as he realizes he went way too technical for her and softens his expression in understanding. "My spark." He replies simply.

"Your what?" Carly, not paying attention, tilts her head, as she is still trying to make sense of what the Autobot had said.

"Ah, forgive my oversight." Optimus amends, "I forget you are not nearly as well acquainted with Cybertronians as Samuel is. The Spark is the Cybertronian's 'heart', Carly, in that it serves a nearly identical purpose."

Carly's eyes go wide with the sudden understanding and she timidly withdraws her hands a few inches from the warm metal, "Oh… my," she whispers. Optimus' expression is tender, humbled by her reaction. His lips curve in the subtlest of smiles and he lets his head fall back to rest on his arm once again.

Carly's mind is filled with curiosity, her year of anatomy and physiology study in college comes flooding back. She has always had a fascination with physiology and now that she is faced with this very alien life form, she struggles to understand him. Despite being comprised of mechanical parts, this being has obvious biologically structured physiology.

Deeply intrigued, she now pays closer attention to what she feels, sees and hears as her experience continues to change and develop. The whisper of hydraulics catches her attention and she blinks a few times to refocus her eyes and watches Optimus lift the vape pen to his lips and take a robust drag. She can't help but smile in amusement as his chest rises, lifting her along with it. He holds his breath for a span of nearly twenty seconds before letting it out heavily.

As the big cloud of vapor mingles with the branches of the trees above them a ripple of warmth spreads across Optimus' body and Carly clenches her jaw a bit, drawing a sudden breath as she feels the thrumming of the Cybertronian's 'heart' tangibly quicken beneath her. Optimus lifts his head and intentionally locks gazes with Carly because he knows what's about to happen. He just took a massive hit and flooded his nervous system with chemicals; he's about to get very 'high', very fast.

Carly's stare is drawn into the deep cobalt blue of Optimus' irises and as she almost subconsciously notices the cough-like hitch in the big Autobot's breathing she watches his optics flare brightly, his lips part slightly and he lets out a soft huff as his pupils dilate right before her eyes. His head is swimming with euphoria now and he smiles at her before letting his head fall back to the ground. "Did you catch all of that, Carly?" he whispers, closing his optics and enjoying the steady onslaught of sensations.

Carly nods, "yes, that was quite a strong reaction. I wasn't really expecting any of that. Of course, I've been comparing you to humans so apparently the reactions are going to be quite different I see." Her words become soft as she notices the racing of Prime's spark beneath her. She smiles inwardly as she is able to draw at least that analog between humans and Cybertronians.

"Mmmh," is all Optimus can manage to vocalize as he is swallowed up in this lovely high. His whole body has become quite sensitive and almost tingles. He can almost feel every blade of grass as they brush against the sides of his immense body. He can feel the minute points of cool water that have condensed on his armor in the mild chill of the evening. He can distinctly feel Carly's weight on his sternal shielding. Her warm body pressed against his chest armor presents a whole new host of sensations to him. The tiny trembling of her muscles as they tense to support her, the rush of her blood beneath her warm skin with her pulse.

Every move Carly makes now sends thrills of sensation through his chest and with a sudden start, Optimus realizes with a distinct jolt that he has placed Carly in a now even more sensitive than usual place. Directly after this realization he trembles subtly with a wave of pleasant static tingling. His second realization hits home as his abdomen tenses involuntarily, he may very soon be introducing her to his more visceral side after a few more minutes in this heightened sensory state.

A tremor shakes his massive frame, immediately causing Carly to drop forward to her hands and knees to stay balanced. Unbeknownst to her, this change in position sent a jolt of ecstasy through his body. Concern paints her face and she peers down towards Optimus' face, "Optimus? Are you alright?"

"Yes," he manages to start softly, "Carly, I'm aware that humans view certain things differently than Cybertronians," Optimus has a rather difficult time maintaining an even tone through the sentence as the accidental stimulation intensifies when Carly relaxes on her belly across his sternum. "But I am afraid we have, um, stumbled into a now unavoidable situation." He swallows hard, placing the vape pen on the ground beside him for the time being.

"What do you mean, Optimus? What's wrong?" Carly's worried expression slowly goes neutral, then as she again becomes aware of Optimus' spark as it beats hard and fast beneath her and his quickened breaths.

"I'm sorry to be so… terribly forward with you," he takes a long breath, "but you seem to have inadvertently stumbled upon my most sensitive of areas and… I am now… perhaps past the point of no return."

Carly stares at Optimus' face as eerily familiar expressions start to show. She can actually see his pulse in the thick cables of his neck and it at last dawns on her what he was referring to when he said 'sensitive'. "Oh, my God! I'm so sorry Optimus!"

"No, no, it's fine. Don't apologize." He manages to smile gently, "Now, this can go one of two ways," He grunts with a spasm as Carly sits up.

"Sorry."

"Either you lay back down flat against my chest and hold on for the ride, or I put you on the ground and I'll finish what you seem to have started. The choice is yours."

Carly's mind is swamped with innumerable thoughts but one gut feeling takes over.

If this is anything like what she thinks it is, Optimus Prime is about to get off and she is not the type to deny any man that pleasure, so without another word she lies down on the warm metal of Prime's sternum. Her hands slide timidly across the smooth metal to rest, palms down, by her head as it rests against his sternum.

Absently, her fingers gently caress the metal as Optimus starts to tremble and twitch beneath her. A sudden, unabashed moan of pleasure slips from his lips and Carly's eyes go wide as Prime's hands shoot out and slam into the ground, his fingers digging into the soil.

A/N

EHRMAHGHERD! So I gotta type more and I guess it will just have to end up as a SECOND CHAPTER! Awkward as it may be mind you.

I don't really know why this story happened, but I had a hell of a good time with it and it came outta nowhere. I just couldn't resist. I ran with it. Don't hate!
