Universal Testing Machines and its assessment in various industries.

The development of a universal testing machine involves several key components and considerations to ensure its functionality, accuracy, and versatility in performing a wide range of mechanical tests. The development of a UTM requires careful consideration of all these aspects to create a reliable and versatile testing machine that can accurately perform various mechanical tests on different types of materials. It is important to engage experienced engineers and experts in the field to ensure the successful development of a high-quality UTM. The development process begins with the design and construction of the UTM. This includes determining the load capacity, frame design, dimensions, and overall structure of the machine. The UTM needs to be robust and stable to withstand the forces applied during testing. A load cell is a vital component of a UTM as it measures the applied force during testing. Load cells are designed to convert the mechanical force into an electrical signal that can be measured and recorded. The selection of an appropriate load cell depends on the load capacity and accuracy requirements of the UTM.  Grips and fixtures are used to hold the test specimen securely in place during testing. They come in various designs and configurations to accommodate different types of materials and testing requirements. The selection of grips and fixtures depends on the specific tests to be conducted using the UTM. Actuators and drive systems are responsible for applying the force to the test specimen. Common types of actuators used in UTMs include hydraulic, pneumatic, and electric actuators. The selection depends on factors such as the required force capacity, speed, and control capabilities. The UTM requires a control system to manage the testing process, collect data, and provide control parameters. The control system may include a user interface, data acquisition unit, load and displacement control mechanisms, and software for data analysis and reporting. The software should be user-friendly and capable of performing various calculations and generating test reports. Safety is a crucial aspect of UTM development. The machine should incorporate safety features such as emergency stop buttons, overload protection mechanisms, and safety interlocks to ensure the well-being of the operator and prevent damage to the machine or test specimen. Calibration is essential to ensure the accuracy and reliability of the UTM. The machine needs to be calibrated using traceable standards to establish its performance characteristics and ensure that it meets the required accuracy standards for force and displacement measurements. UTMs are often designed to comply with international standards such as ASTM, ISO, or specific industry standards. Ensuring compliance allows for consistency and comparability of test results across different laboratories and industries. Proper training and technical support should be provided to users of the UTM to ensure its correct operation, maintenance, and troubleshooting. User manuals, training programs, and technical assistance should be available to help users maximize the capabilities of the machine. 

An industrial tensile testing machine, also known as a universal testing machine (UTM) or a materials testing machine, is a specialized equipment used to perform tensile tests on various materials. These machines are designed to determine the mechanical properties, strength, and performance of materials under tension. The load frame is the main structure of the machine and provides the rigidity and stability required for accurate testing. It consists of a fixed and movable crosshead, where the specimen is held and subjected to tension. The actuator is responsible for applying the tensile force to the specimen. It can be hydraulic, pneumatic, or electric, depending on the specific machine design. The actuator controls the speed and rate at which the force is applied to the specimen. A load cell is used to measure the applied force during the tensile test. It converts the mechanical force into an electrical signal that can be measured and recorded. The load cell is selected based on the required force capacity and accuracy of the machine. Grips and fixtures are used to securely hold the test specimen in place during the test. They come in various designs and configurations depending on the type and size of the specimen. Grip options include mechanical, pneumatic, or hydraulic grips, as well as specialized grips for specific materials or test requirements.  Industrial tensile testing machines include a displacement measurement system to measure the elongation or deformation of the specimen during the test. This can be achieved using an extensometer, LVDT (linear variable differential transformer), or an encoder. The displacement measurement allows for the calculation of strain and stress-strain curves. The control system of the machine includes a user interface, data acquisition unit, and control mechanisms. The software provides control over the testing process, data collection, and analysis. It enables users to set parameters, monitor the test progress, and generate test reports. Safety features are incorporated to protect operators and prevent damage to the machine and test specimen. These may include emergency stop buttons, overload protection mechanisms, and safety interlocks, Industrial tensile testing machines are often designed to comply with international standards such as ASTM, ISO, or specific industry standards. Compliance ensures the consistency and comparability of test results across different laboratories and industries. 

Universal testing machines (UTMs) are versatile testing equipment used to evaluate the mechanical properties of materials. They are widely utilized across industries for various testing applications.  These UTMs are designed to perform both tension and compression tests. They are used to measure the tensile strength, yield strength, elongation, compression strength, and modulus of elasticity of materials. Typical applications include testing metals, plastics, textiles, elastomers, and composites.Bend testing machines apply a three-point or four-point bending force to evaluate the flexural strength, modulus of elasticity, and deformation behavior of materials. These machines are commonly used for testing beams, bars, rods, and other structural components. Flexure testing machines determine the flexural properties and behavior of materials. They are used to evaluate the flexural strength, modulus of rupture, and flexural modulus of materials such as ceramics, concrete, fiber-reinforced composites, and wood. Compression testing machines are specifically designed for compressive strength testing. They measure the compression strength, deformation behavior, and elastic properties of materials. Common applications include testing concrete, rock, foams, and packaging materials. Shear testing machines apply a shear force to evaluate the shear strength and behavior of materials. They are used to determine the shear modulus, shear strength, and shear strain of materials such as adhesives, composites, and soils. Torsion testing machines measure the torsional strength, torsional modulus, and shear stress-strain characteristics of materials. They are primarily used to test materials subjected to rotational or twisting forces, including metals, plastics, and composite materials. Fatigue testing machines are designed to assess the endurance and fatigue behavior of materials under cyclic loading conditions. They simulate repeated stress cycles to evaluate material fatigue strength and fatigue life. Fatigue testing is critical in industries such as automotive, aerospace, and structural engineering. Although not strictly universal testing machines, hardness testing machines are often categorized within this group. They measure the hardness of materials, providing an indication of their resistance to indentation or penetration. Common hardness testing methods include Rockwell, Brinell, and Vickers hardness tests. 

The specific type of universal testing machine selected depends on the testing requirements, material properties, and industry standards. These machines are used in research and development, quality control, material selection, and compliance testing across a wide range of industries, including automotive, aerospace, construction, manufacturing, and materials science.

Torture. That’s how you would describe this shift. 

Usually, you get lost in it. The never ending ebb and flow of the emergency department. A wave that carries you from one patient to the next, from one test of your knowledge and skills to another.

But today, all you can think about is what Robby whispered to you this morning when you were still half-asleep and tangled up in each other.

“Be a good girl today and I’ll fuck you so good tonight.”

It rattles around your skull as you walk between trauma rooms, as you sit at a computer charting, when you stop to take a sip of water. The silky grate of his sleep-ridden voice. The warm press of his lips on the slope of your neck. And the heat of his hard body leaving you cold and wanting in bed when he so viciously got up to start the coffee machine.

The seconds feel like minutes, the minutes like hours. There’s a hum beneath your skin, a coiling tension that seems to build and build no matter how hard you try to throw yourself into your work. 

Because he’s always there. His dark eyes finding yours across the room. The electric trail of his fingertips sliding across your back as you pass each other on the way to opposite trauma rooms. The stifling heat of his presence beside you as you assess a new patient. 

You’ve always worked so well together. Both of you are so quickly able to leave your relationship at the door, to focus on the work. Today, however, you can hardly think of anything but getting home and jumping his bones.

A couple hours into the shift he has the absolute gall to ask you, “You doing okay? You seem a little tense.”

As if he isn’t the reason you feel like crawling out your own skin. Or shoving him into the nearest on-call room and having your way with him. But you can’t do either and so you settle on giving him a taste of his own medicine.

You lean in close, closer than you should out in the open of the ER like this. And you whisper, sickly sweet, “I’m being a good girl, aren’t I?”

You pull away from Robby, and look up at him with the most innocent eyes you can muster. The change in his demeanor is instantaneous and almost imperceptible. He’s hyper aware of the fact that you're surrounded by watchful eyes and yet he can’t help but be affected. You can see it in the rigidity of his spine, the slight tick of his jaw.

You don’t even give him the chance to respond, turning on your heel and away from the nurses’ station. His hand reaches for you before he can stop it, before he remembers himself. You feel Robby’s eyes boring into your back as you stride down the hallway, turning over your shoulder for a brief moment before the hall bends to find him standing exactly where you left him.

The next time you see each other is in the heat of a code. You’re climbing on top of the hospital bed, focused solely on the rhythm of your compressions. The room is a flurry around you and Robby breezes into the chaos to ask what he can do to help. But you’ve got it under control. The patient’s stats are rising, rhythm returning to that steady and all too familiar beep. There’s a chorus of exhales and nurses and doctors shuffle out and onto the next. 

Robby reaches over to help you down from your position straddled on the bed, the warmth of his hands seeping through the sharp cotton of your scrubs. Before you know it, you're the only other people left in the room. A now stable patient seemingly in the hands of two very capable doctors. 

Save for an unconscious woman, it's the first time you’ve been alone since you arrived to work this morning. At separate entrances and 8 minutes apart, like always. 

The quiet of the room is deafening. You wonder if he can hear the pounding of your heartbeat. Neither of you say anything, the air thick with want.

You’re standing too close but you don’t move. You don’t dare look at his face, eyes focused on the string of his hoodie that trails down his chest. Scared of what you might do, what he might do now that you’re alone.

Robby fingers the hem of your scrub top and laughs, but there’s no humor in it.

“You’re not playing fair,” he grits out. You bite your lip but don’t say anything. He fists the hem of your top now and pulls you closer to him.

“Look at me,” he says, his voice low and dark. Your eyes snap to his, spine alight with anticipation. You know that voice and what it means. As much as his words read like a command, you can see the pure desperation in eyes. He’s a man hanging on by a very thin thread.

“I’m not the one who started the game,” you bite back. Raising your chin and baring your neck in the process. An invitation, a supplication.

Robby’s hand releases your top and presses into your waist, trailing upwards until it rests just beneath your bra. So close and yet so far from where you want it. You open your mouth, a plea on the tip of your tongue when Dana bursts in. 

“Incoming trauma. Two teenagers pulled out of a burning building,” she calls out.

You’re angled away from the door and you know that she can’t see where Robby’s hand rests. But she can see how close you stand and you can hear the mirth in her voice at finding you both in this position. 

“We’ll be right there,” Robby responds, his eyes never leaving your face. The door swings shut behind her and his jaw ticks as he shakes his head. He steps back and massages the bridge of his nose for a moment. When he opens his eyes once again they’re burning hot with need.

“You’re killing me,” he whispers. His hands placed on his hips to keep himself from reaching out for you again.

“How do you think I feel?” you ask, shifting between your feet. Wanting to move closer and further away at the same time. The decision is made for you when a stampede of nurses and doctors pass by the door, pulling you from the quiet tension of the room and back into the fray.

It’s not until there’s only two hours left in the shift that you actually have a chance to think again. And of course Robby is there to fill every open millimeter in your mind. You stand on opposite sides of the nurses’ station and he hasn’t quite noticed your arrival, stuck in conversation with an intern. 

The doctor turns to go and Robby reaches his hands up to clasp them, bending his arms at the elbows so his fists rest between his shoulder blades for a deep stretch. The movement causes his sweatshirt and scrub top to ride up, revealing the skin of his soft lower belly and the wiry happy trail that disappears into his cargo pants.

Your mind goes blank, flashes white hot with pure desire. You absent-mindedly lick your lips and when you finally tear your eyes away to his face, you find he’s already looking at you. You’re caught.

His eyes are unreadable but dark and Robby all but prowls around the station to reach you. He relaxes his back against the counter beside you, one arm bent to rest on the vinyl surface and the other one, the one closer to you, hangs down between your bodies. 

There’s a beat of silence before he speaks. His voice is low, and his words burn through you.

“I don’t know if you’re being good enough, honey,” he murmurs. Just barely loud enough for you to hear over the room around you.

You try not to react and you think you’re successful besides the way your knees wobble for a brief second. You think maybe you’re delirious and the shift is getting to you because he couldn’t possibly be saying this to you right here, right now. But Robby continues.

“I was gonna make you come on my tongue at least twice before I gave you my cock. But now, now I’m not so sure,” he says, voice as even and neutral as if he was telling you his lunch order. He doesn’t look at you and you don’t look at him. 

You gulp and your lips part but no words come out. He fills the silence anyways.

“Maybe you shouldn’t get to come tonight,” he whispers. “I’m not sure you deserve it after you’ve had me half-hard this entire shift.” 

Your eyes flash to his at that and you swear you can see glowing embers in his irises. You bite the inside of your cheek to keep from begging.

“Maybe I won’t even touch you,” Robby rumbles. “Make you watch as I—” 

Your hand darts out to grab his wrist so fast it’s almost a reflex. Nearly your entire body is tense now. The thought of spending the night without his touch to ease the tension that has been building for hours is too much for your fried brain to handle.

“Robby,” you grit out. “Please. ”

The corner of his mouth quirks up, self-satisfaction evident in his face.

“Ah there she is,” his voice carries praise now. “Guess my good girl came to work after all.”

The words wash over you like honey, the sparking fire in your belly replaced by warm, ambling lava. Your shoulders finally relax and Robby’s hand pulls his wrist from your grip so that he can interlace your fingers and squeeze. After a second they slip away.

Your eyes narrow at him.

“You, Doctor, are inhibiting my work,” you admonish now that the moment has passed. 

His grin is full and he pushes off the counter with his palms up as a peace offering. 

“Guilty as charged,” he admits as he backs away.

You pick up your discarded tablet and try to remember what you were looking for when Robby interrupted. After a moment, Dana comes to stand in front of you.

“What was that all about?” she questions, eyebrows quirked over her glasses.

“Oh, just discussing a patient,” you lie through your teeth, hoping she can’t see the way your skin still burns.

“Sure kid,” Dana relents, a knowing smile on her face. “Whatever you say.”

She departs, fielding questions as a couple of residents return from their patients. You blow a deep breath out and glance at the clock. 1 hour 53 minutes left in the shift. You roll your shoulders. You can do this.

The promise of sweet relief finally comes in the form of Jack Abbott marching through the emergency department doors. His arrival means that shift change is thankfully upon you, and not a minute too soon.

The night shift shuffles in behind him, their rested and renewed faces a stark contrast to the dozen or so hours you and all your fellow day-shifters wear.

You make your way to the nurses station to return your tablet and find Robby and Abbott embraced in what can only be described as a “bro hug.” As you put the device back on the charger you overhear the two talking.

“Okay, so that’s all for me. I’ll see you in 12,” Robby finishes recapping the shift. You can almost hear the way he shoves his hands into his zip-up pockets from his voice alone.

“You’re eager to get out of here,” Abbott remarks, and as you turn around you see the way his eyes dart between you and Robby. “Got a hot date or something?”

Robby looks over to meet your gaze for a moment, and you see the promise of what’s to come in them. 

“Something like that,” he laughs, taut and almost painful, as you turn and make a beeline for the locker room.

You’re practically shoving your belongings into your tote, suddenly filled with renewed energy despite the draining shift you’ve endured. Robby enters the room as you’ve just about finished and doesn’t even check to see if he has everything in his backpack, just pulls it from the locker and slams the door shut.

In an uncharacteristic move, you make your way out of the emergency department together, forgoing the usual staggered exit by unspoken agreement. You’re so close your fingers brush with nearly every step but you don’t dare move further apart. You think the effort of doing so might actually kill you.

The silence between you stretches all the way to the car. Both of you a razor-thin edge away from losing control and knowing that if you break now, there’s no way you would make it out of this parking lot without scandalizing at least a couple of your coworkers. 

Robby still opens the passenger door for you and slips your tote off your shoulder to place it in the backseat with his backpack as he always does.

The car ride is silent too, the quiet before the storm. At a red light you lock eyes and can’t help but smile at each other. He leans over to press a kiss to your forehead. A tender moment in the eye of the hurricane.

When you finally make it home, he carries your bags up the steps as you unlock the front door. The buzzing under your skin returns in full force now. Sweet anticipation crawls up your spine as you watch him hang your things in the entryway.

“Shower,” Robby bites out, breaking the tenuous quiet. He takes a step towards you.

“Alone,” you add and he stops, his eyes nearly begging. You know what will happen if you take one together and you want him in the warmth of your bed. For hours. 

“Don’t even think about deep conditioning, Robinavitch,” you warn him and he struggles to bite back a smile as he scratches the back of his neck. You want, no need , to wash off the day but that doesn’t mean you can wait a second longer than you absolutely have to.

“Yes ma’am,” he agrees and you take off in opposite directions through the house, grateful for the guest bathroom in a way you never have been before.

You’re clinical and efficient as you scrub your body in the shower, not even waiting for the water to warm to your preferred temperature before jumping in. You barely towel off and definitely don’t bother to squeegee the glass shower door before you make your way to your bedroom, a robe haphazardly tied around you.

Robby is already there, pacing in just a towel tied loosely around his waist. The outline of his cock pushes against the fabric, half-hard, just like he said. Your eyes flick up from his waistline and you don’t bother hiding the smirk on your face.

“Guess you weren’t kidding,” you tease and relish in the tightening of his jaw.

“Jesus,” he groans and shakes his head, “You think this is funny or something?” 

He stalks towards you and his fingers tangle in the tie at your waist.

“Maybe a little,” you bait him, and he falls for it. Robby rips the robe open and off your shoulders. His considerable hands settle on the soft skin of your hips. He grips them and pushes you towards the bed, somehow gentle and insistent all at once as he lowers you down onto it. 

He follows a rivulet of water as it cascades down the slope of your tit with his thumb and quickly follows another with his tongue, deviating course to trace your nipple. You can‘t help the gasp that escapes you, and your back arches, pushing your body towards his open mouth. He gruffs a laugh out against your skin and now his whole mouth closes around your nipple.

He pops off one tightened bud and places open mouthed kisses across your sternum to reach the other. He doesn’t dare leave either wanting, his palm massaging whichever is neglected by the wet heat of his mouth.

It’s too much and not enough at the same time. You’ve been aching for him all day and he’s barely scratching the surface of the pure need inside you. You try to reach for the towel, hoping getting him all the way naked might speed things up. But he just swats your hands away.

“Greedy,” Robby mocks into your chest. He pushes up from your body and you feel the loss of him keenly. You buck your hips up into his but it doesn’t sway him.

“Good girls know how to be patient,” he chides as his thumb leisurely trails across your abdomen. 

“I need more Robby, please,” you whimper. You can’t control the shifting of your hips or the tight grip your fists have on the comforter beneath you. 

His hand trails further down your body, two fingers finally sliding down to your cunt to swipe through the pleasure dripping from you. 

“Oh she needs more does she?” Robby taunts. He can see your expression begin to shift before it even happens, that pout you get when he makes you wait. You’re on the edge and he can tell. 

“Okay honey,” he says and he gives it to you. Thrusts two thick fingers into your pussy without any warning and watches from above as your body arches obscenely off the bed, a moan pulled from deep inside you. The pace he sets is unrelenting and it’s exactly what you need. His other hand comes up to grip the back of your neck, grounding you. You grip his wrist. 

Without ceremony he adds another finger, not stopping to give you a moment to adjust. The burn is delicious, pushing you towards a long-awaited peak. He curls his fingers inside you.

“Fuck–uh–uh–uh,” you hiccup. “Yes. ” 

“My fingers feel good, baby?” he asks, breathless right alongside you.

You nod your head and don’t stop as his thumb moves to circle your clit. It’s the final push you need, your climax fast approaching.

“Was I good?” you whimper, thighs pressing together around his hand inside you. “Are you gonna let me come?”

You’re not sure you could stop it even if you tried but you don’t have to worry. Robby’s pace picks up, somehow, and the thumb on your clit presses down harder.

“Perfect,” he whispers, reverent. “You’re perfect.”

And that sends you over the edge. Robby swallows your scream with his mouth, your kisses messy and tactless but filled with aching passion. He keeps his rhythm through the aftershocks, working you through it as the pulses around his fingers taper out.  

He pulls away from your mouth with a final press of his lips and you pant into the warm air. His fingers slide out of you with a squelch and you whimper at the loss. Robby brings his fingers to his mouth, eyes closing as his lips do, as if savoring the taste.

You hum and your arms reach out for him but his mouth moves down your body, like he’s searching for more, for the source of you. He’s gentle as he bends your legs to rest your feet on the bed, settling between your open thighs with his wrists around your ankles. He descends on your cunt without preamble. His mouth moves between your clit and your hole with ease and precision. It feels good, amazing, but it’s not what you want.

“No, baby, ” you cry out through the pleasure. “I want you.”

Robby doesn’t stop. His tongue curls into you, around your clit. 

“I’m right here,” he murmurs when he comes up for air. His eyes peer up at you as his mouth continues its assault.

You push up onto your elbows and reach a hand down to thread through his hair. You tug his head back, pulling him off of your dripping pussy, mouth still hanging open and beard slick with you.

“No,” you command. “Inside me.”

That gets Robby moving, wiping your slick from his mouth on the inside of your thighs as he moves his body up yours. Your feet push at his towel, unraveling it from around him. He tosses it to the ground, careless.

He settles his weight over you. His lips press into your collarbone, into the slope of your neck, across the apple of your check. Finally he kisses you fully, deeply. The taste of you remains on his tongue. 

There’s a shift of Robby’s hips as he notches his thick head into your aching hole and then he’s pressing inside. Wide and heavy, and almost too much to bear even with the slick that eases his entry. The inches keep coming, stretching you open in a way that feels indecent.

When you’ve finally taken every delicious inch and the tip of him presses into that spongy spot inside you, his head collapses into the juncture of your neck.

“So fucking good,” he mumbles into your taut skin.

You wiggle your hips, searching for more. His hands press them down into the bed with a huff. You whine and Robby lifts his head to find your eyes.

“Just give me a sec,” he pleads, completely undone by the feel of you. You’d be smug about the fact that he’s struggling not to come from just pushing inside you if you could feel anything beyond the raw and unadulterated stretch of him.

You’re trying to be patient but every second he’s not moving makes it harder and harder not to chase the pleasure that simmers beneath your skin. You sneak your hand down between your bodies to circle your clit. You get maybe two desperate swipes before Robby shoves your hand away and pulls out of you.

He thrusts back into you so hard and fast you think you might actually see stars. The noise that leaves your mouth sounds inhuman even to your own ears.

“Nu-uh honey,” Robby tuts, as he sets a pace that has you gasping with every thrust. 

“Mine.” 

The word is gritted through his teeth. Your hands come up to grip his biceps. Your nails dig into the thick muscle, looking for something to ground you.

“You just lie back and be good,” he rumbles. The words send warmth rushing through you. You can do that. You can be good for him.

Your hands glide across his shoulders, down his chest, and to his back. You pull his body closer to yours. The friction between your nipples and the hard and hairy lines of his chest sends sparks of pleasure coursing through you.

You’re almost at the peak of another orgasm and he can feel it with the way your walls are beginning to close in around his aching dick. Robby’s hand hooks under your right knee and hoists it up and past your hip, pressing it into the mattress and opening you up even more for him.

It feels ridiculously good and the sensation of being so stretched open has you babbling. A string of whiny pleases and whimpering moans followed by a singular plea.

“Don’t stop, don’t fucking stop.”

Robby’s thumb traces over the knee he holds hostage. His tender and soft touch, a juxtaposition to the way his cock slams into you.

“Wasn’t planning on it, sweetheart,” he teases and leans down to kiss the furrow between your brows.

Your orgasm explodes through you, feet kicking out and head tossed back with the sensation. Robby’s pace doesn't let up, just carries you through the waves of pleasure washing over you. Only when he’s wrung out every last squeeze of your cunt does he slow to a stop inside you.

He peppers kisses across your cheeks and nose and forehead as you pant and return back to your body. His tongue darts out to cull the droplets of sweat gathering at your hairline. Your moans are content as you bask in the afterglow.

“Good?” Robby asks as he noses at your ear.

You nod and mumble an affirmation.

“Soooooo good,” you sigh, words slurring. 

He chuckles and suddenly you’re reminded of the fact that he’s still rock hard inside you.

“That’s my girl. I’m not done with you yet,” he rumbles as he pulls out of you, sticky and wet. 

You whine. Didn’t he just say he wasn’t done with you.  

Robby shushes you and he’s careful as he maneuvers you over and onto your knees. A warm palm on your back pushes your chest into the bed and you settle your cheek on a cool patch of sheets. Your spine stretches out as you relax into this new position.

“Just like that, baby,” Robby groans, settling behind you with a grip on your hips. “I’ve been waiting for this all fucking day.”

“Yeah? All day?” you ask, mirth back in your voice as you turn over your shoulder to look at him.

His jaw ticks and he presses his hard cock against the curve of your ass.

“You’re a pain in my ass, you know that?” he grits out.

“Actually,” you taunt as you push back against his cock. “I think you’re the one who’s a pain in my aa –”

Your banter is cut short as Robby pushes into your wet and waiting cunt. You think you should be used to it by now but the stretch of him always catches you by surprise, has white hot bliss spreading through you like wildfire.

“That’s what I thought,” he hisses as he pumps in and out of you. “All I gotta do is put my cock in you and you can’t even speak.”

You try to respond but all that comes out is a gurgle of moans. He picks up his pace and his thrusts have you moving up the bed a couple inches.

“Guess I should have done this when you were mouthing off to me at central,” he huffs, panting with the effort of the tempo he’s set.

“Asking me if you were a good girl in front of the entire ER.” His palm comes down with a smack across your ass. 

You keen and push back to meet his thrusts.

“Bet you would have liked that,” he laughs. “Come on baby, tell me what we look for when a patient presents with expressive aphasia.” 

Is he seriously fucking quizzing you right now? That smug bastard. Your brain struggles for the answer. It’s on the tip of your tongue but every time you get close to the answer his cock hits that spot inside you that has your brain going blank.

“R-Robby, I can’t…I don’t–” you whimper into the bedsheets.

“I know, honey,” he coos from above you. “Maybe you’ll remember how much of a mess my cock makes you next time you want to be such a fucking tease at work.”

You clamp your cunt down around him. He grunts and his pace stutters.

“You s-started it,” you cry out. You squeeze around him again.

Robby’s tempo turns erratic and you know he’s close. You can feel yourself riding the edge of a third orgasm and you want him to come with you. You know just how to get him there.

“Dr. Robby,” you plead, voice breathy and sweet. You feel the way his fingertips dig into the plush skin of your lower back.  “I want you to come inside me.”

He moans, breathes out a trail of curses. The way you say his name like that, the way you beg for his cum when you know it drives him fucking wild. Robby can no longer think of anything else.

“Please. I need it.” you beg.

With a final, brutal thrust his orgasm slams into him, and you shatter right alongside him. He spills deep inside you, warm cum coaxed from his impossibly hard cock by the fluttering of your tight cunt. Your name is a stuttered moan on his tongue.

He collapses on top of you, teeth finding purchase in your shoulder as you float back down to earth together. Robby eases his bite with a soft press of his lips and he’s tender as he rolls you onto your sides together. His hand slides up from your hip to splay across your belly and he nuzzles into the back of your neck.

You both hum when Robby slips his softening cock from you, his spend spilling out and down your thighs. He pulls you back into him as you stretch your legs out beneath you.

After your heart rates settle, Robby pushes up from the bed and stumbles into the bathroom. Knowing that if he’s done his job right, and he has, you won’t be able to walk over there by yourself just yet.

Warm and sated, you hear the tap run. And then he’s back, sliding a warm washcloth between your legs. You sigh at the care with which he cleans you, all the delicacy and precision of the incredible doctor you know him to be.

He settles back onto the bed beside you and pulls a blanket over your intertwined bodies. You nestle into Robby’s chest and his hands come to thread through your still damp hair, brushing it out behind you.

“I’m way too old to be trying to hide a boner at work,” he laughs into your hairline. You giggle and pull back so you can look in his beautiful, brown eyes.

“And whose fault is that, hmm?” you tease and the corners of his mouth quirk up. His thumb comes up to trace along your cheek. He leans in to press a soft kiss to your lips. 

“I wish I could say I was sorry,” Robby smiles, “but fuck baby, you drive me crazy.”

“Ditto, old man,” you agree and he rolls his eyes. “Next time, save it for a day off, or at least shift change.”

He grins and pulls you closer. 

“Yes doctor, right away doctor,” he sighs, always the theatric, in between kisses across your face. Now it's your turn to roll your eyes.

Bliss. That’s how you’d describe this post-sex cuddle in the bed you share.
