For the first time in what feels like forever, the medical bay is empty. There's not a single spark i sight, which means that First Aid can finally enjoy some downtime.
You peer up at him, focusing on how his bright blue visor flickers with overstimulation as your tongue refuses to let up on his leaking valve. He's gripping onto the seat of the stool for dear life, nearly on the verge of breaking it. This wasn't how he thought his workday would go, but you're always full of surprises. He also never thought that he'd be having his valve eaten in one of the empty bays of his medical unit.
He's so beautiful when his processor is running amok because of you. He's a quivering, endearing mess. It's something he just can't control around you.
You're practically making out with his valve. You're being messy and sloppy, making sure to target all the good bits that have his circuits frying in no time. He prefers this over clean, precise licks. It's funny how people differ in the berth compared to how they are on a day-to-day basis.
"Primus, have mercy," he whispers, "Don't stop. Please don't stop, it feels so good exactly where you are."
He can be needy, even more so when you're paying special attention to his anterior node. Your tongue moves languidly, easily finding every sweet spot he has. Your tongue feels so much better than a Cybertronian glossa.
His frame is heating up, causing his cooling fans to activate. Whirring sounds emit from him, which is beyond sexy. It wouldn't have done anything for you before your life merged with mechanical beings, but now? That's an entirely different story.
You couldn't stop even if you wanted to. You're far too into this, and the rhythm you've found begs not to be broken. You'll stay on this path until you have him releasing all over your tongue.
You take your hand to the entrance of his valve, pairing two fingers together before pushing in. His helm rolls with bliss as you part the callipers that line his walls. The pads of your fingers find his interior node, and you immediately start to beckon up against it.
With both nodes receiving a constant flow of stimulation, he moans in a high pitch. His hips buck ever so slightly, but you manage to stay on him. You moan into the hot metal of his valve, feeling his prefluids already gathering over your plump lips.
"Ah! Ah!" He whimpers pathetically, rolling his hips. You huff a short laugh, entertained by his pleasured antics.
Fluid trickles down the crack between your fingers and spreads into the palm of your hand. Your tongue flicks his anterior node with expert precision, excited to see him coming undone in front of you.
"Mmhh—phh!" He whines as his leg struts start to shake. He vents deeply and heavily, gripping the stool impossibly tighter as he reaches his climax. His vocaliser cuts out mid-moan, left to enjoy his ecstasy with nothing but the sound of your fingering and licking.
You hum as his taste swarms over the buds of your tongue, seeping into every corner of your mouth. Giving one last long lick over his valve, you finally part from him, pulling your fingers out at the same time.
You suck the fluids off your fingers, making sure to make eye contact with him as you do so. He's besotted with the sight, almost to a humiliating degree.
"Go sit on the berth," you say with a nod towards the medical berth behind him.
He looks over his shoulder behind him, weighing up the consequences of doing something so lewd in a place designed for sanctuary and curing. It's a doubt that only lingers for a moment, a moment cut short by a flood of bodily memories of how good your pussy feels. He stands from the stool without even thinking to do so, moving over to the berth as though it yields a gravitational pull.
You grin at his obedience, standing from your kneeling position and wiping your wet fingers on your top. You follow him over as he sits on the edge of the bed, eager optics awaiting your arrival.
"Can you take your spike out for me?" You hush sultrily, eyeing up his interface panels.
He nods, utterly distracted by the shape of you. You giggle lightly as you notice his ogling, and you decide to gratify him further. As he disengages his panels, you start undressing.
First goes your top, then your shorts, discarded onto the floor. Next, your bra, and then your underwear. They both join the pile of your clothes, and they'll remain there until you're both done with your fun.
You hear his vents work harder, his shielded optics tracing the lines of your body. He never thought he'd be so intimately intrigued by an organic.
Taking one step closer, you reach out to grab his servo. You bring two of his digits to your mouth, sucking on them to slicken them. Behind his mask, his intake drops.
You pop them out of your mouth, leading them between your legs. He gets the memo, taking the initiative to stroke his newly wet digits against your hole. You sigh a soft moan at the delicate touch. It's a bit difficult to take him without having any foreplay received on your part, but you're too desperate for his spike to delay it any longer.
He withdraws his digits, settling his servo by his side whilst patiently waiting for you to make the next move. You settle your hands on his shoulders before hiking your legs up to straddle him. You hover over his spike, nestling it in the arch between your legs.
You shift your weight down, slipping his spike inside. He huffs with a moan as your heat starts to envelop him, working your way down inch by inch.
Tucking your head into the crook of his neck, you start to litter the intricate metal with hot kisses. Your hips bounce on him, nice and steady.
He whimpers as you drag your tongue along the fuel lines on his neck. Your hips roll steadily over him, feeding his leaking spike into your pussy over and over again.
You slide your hands down his frame, following over to his arm struts to take his servos into your hands. You lead them to your ass, prompting him to grab on. You fit perfectly in his servos, like a lock and key.
"Don't be shy," you coo against his neck. "You can grab it properly."
"O—Okay," he stammers back. He gives an experimental squeeze, letting the soft flesh spill in the gaps between his digits.
You let out a little breathy moan, enjoying the feeling of his talented servos being so crude with you.
"Keep going," you plead.
He heeds you, squeezing again. He finds a rhythm with it, and realises he enjoys the way your ass gives under his touch. He hums a small moan, being so bold as to actually assist you in riding him.
It helps your aching thigh muscles, which you're grateful for. You start moaning heavier against the metal of his neck, tucking your face in further. Your tongue comes back out, tracing along the ridges. He mewls and whimpers at how sensitive he is, and it serves as fuel to make you ride faster and harder.
Ever so lightly, you graze your blunt teeth against his main energon line. A staticky gasp leaves him, feeling startled. You giggle, pulling away from his neck to face him. Your eyes look through his visor, seeing his barely visible optics beneath. You draw him to pepper kisses over his mask, settling one hand on the side of his neck and the other on his shoulder.
"You feel so good," he compliments, the words causing his mask to vibrate. It sends a pleasant sensation over your lips, almost ticklish.
"I'm glad," you hush back, "You deserve some respite every now and then."
You press your chest up against his chassis, seeking to be as close as possible to him. He welcomes it, squeezing your ass harder. He's moaning beneath his mask, trying to control himself out of worry that someone might hear. This is a grossly inappropriate way to conduct himself in his medbays.
"Ah—" he whimpers, "I'm gonna overload."
Maybe the risk of semi-public sex really does something for him. This is quick for him to find his release, but you certainly aren't complaining.
He lets out a long, deep-rooted moan as his spike twitches inside of you, dumping a heavy load of transfluid into you. You gasp, arching your back at the warmth spreading through you. His visor flickers with light as his fans work overtime.
"Mmm," you hum happily, "I love it when you overload."
"G—Good thing you're so good at making me doing it," he babbles.
You continue riding him, now looking to carve out your own pleasure this evening. You gasp little moans as you move relentlessly on his lap. He shudders with static at how sensitive his spike is, but he makes no motion to stop you.
Winding your hands behind his neck, you single out a couple of wires with nimble fingers. He whines as you gently start caressing them, knowing how sensitive they are.
Your fingers dig in a little as you sense your peak approaching. You throw your head back with a gasp as you focus on that feeling, envisioning how his spike looks going in and out of your sappy pussy. The thoughts are enough to unravel you, your hips staggering as the pleasure pulses through your lower half.
Your release is sweet and hot, your walls clenching around his throbbing spike. It's just the high you needed.
