"When bloodstream infections set in, fast treatment is crucial — but it can take several days to identify the bacteria responsible. A new, rapid-diagnosis sepsis test could cut down on the wait, reducing testing time from as much as a few days to about 13 hours by cutting out a lengthy blood culturing step, researchers report July 24 [2024] in Nature.

“They are pushing the limits of rapid diagnostics for bloodstream infections,” says Pak Kin Wong, a biomedical engineer at Penn State who was not involved in the research. “They are driving toward a direction that will dramatically improve the clinical management of bloodstream infections and sepsis.”

Sepsis — an immune system overreaction to an infection — is a life-threatening condition that strikes nearly 2 million people per year in the United States, killing more than 250,000 (SN: 5/18/08). The condition can also progress to septic shock, a steep drop in blood pressure that damages the kidneys, lungs, liver and other organs. It can be caused by a broad range of different bacteria, making species identification key for personalized treatment of each patient.

In conventional sepsis testing, the blood collected from the patient must first go through a daylong blood culturing step to grow more bacteria for detection. The sample then goes through a second culture for purification before undergoing testing to find the best treatment. During the two to three days required for testing, patients are placed on broad-spectrum antibiotics — a blunt tool designed to stave off a mystery infection that’s better treated by targeted antibiotics after figuring out the specific bacteria causing the infection.

Nanoengineer Tae Hyun Kim and colleagues found a way around the initial 24-hour blood culture.

The workaround starts by injecting a blood sample with nanoparticles decorated with a peptide designed to bind to a wide range of blood-borne pathogens. Magnets then pull out the nanoparticles, and the bound pathogens come with them. Those bacteria are sent directly to the pure culture. Thanks to this binding and sorting process, the bacteria can grow faster without extraneous components in the sample, like blood cells and the previously given broad-spectrum antibiotics, says Kim, of Seoul National University in South Korea.

Cutting out the initial blood culturing step also relies on a new imaging algorithm, Kim says. To test bacteria’s susceptibility to antibiotics, both are placed in the same environment, and scientists observe if and how the antibiotics stunt the bacteria’s growth or kill them. The team’s image detection algorithm can detect subtler changes than the human eye can. So it can identify the species and antibiotic susceptibility with far fewer bacteria cells than the conventional method, thereby reducing the need for long culture times to produce larger colonies.

Though the new method shows promise, Wong says, any new test carries a risk of false negatives, missing bacteria that are actually present in the bloodstream. That in turn can lead to not treating an active infection, and “undertreatment of bloodstream infection can be fatal,” he says. “While the classical blood culture technique is extremely slow, it is very effective in avoiding false negatives.”

Following their laboratory-based experiments, Kim and colleagues tested their new method clinically, running it in parallel with conventional sepsis testing on 190 hospital patients with suspected infections. The testing obtained a 100 percent match on correct bacterial species identification, the team reports. Though more clinical tests are needed, these accuracy results are encouraging so far, Kim says.

The team is continuing to refine their design in hopes of developing a fully automated sepsis blood test that can quickly produce results, even when hospital laboratories are closed overnight. “We really wanted to commercialize this and really make it happen so that we could make impacts to the patients,” Kim says."

Scientists present a modular bond-centric strategy for designing protein nanomaterials that are motivated by the wide range of chemical configurations that may be produced from a limited number of atomic valencies and bonding interactions. Through the application of basic geometric concepts, researchers from the University of Washington create protein building blocks with regular coordination geometries and bonding interactions that facilitate the assembly of a broad range of closed and opened nanomaterials. 

Electron microscopy data closely matches the appropriate design models, and experimental characterization verifies the successful production of over twenty multi-component polyhedral protein cages, 2D arrays, and 3D protein lattices, with a high success rate of 10–50%. Due to its modular design, individual building blocks can be assembled with various partners to create unique regular assemblies. This leads to a reduction in the number of parts needed and makes it possible to develop reconfigurable systems.

Space Elevator and NanoTechnology in The Three-Body Problem

👩‍🚀💙👨‍🔬

Nanotechnology is a highly cross-cutting and comprehensive discipline, which covers a wide range of modern science and technology including nanophysics and nanochemistry. If you have seen the movie Wandering Earth 2, you might be shocked by the "space elevator"! Actually, it is a frequent guest in the best sci-fi novel of the century, Liu Cixin 's The Three-Body Problem works. The nano-abrasive wear mechanism of Wang Miao's research is the basis for producing the space elevator!

The concept of Nanotech is also popular in chemistry. American chemist James Tour designed and synthesized NanoPutians in 2003 for use in chemistry education for young students. NanoPutian is a portmanteau of nanometer and Lilliputian, which is a series of organic molecules with a structure similar to that of the human body.

"A team at Northwestern University has come up with the term “dancing molecules” to describe an invention of synthetic nanofibers which they say have the potential to quicken the regeneration of cartilage damage beyond what our body is capable of.

The moniker was coined back in November 2021, when the same team introduced an injection of these molecules to repair tissues and reverse paralysis after severe spinal cord injuries in mice.

Now they’ve applied the same therapeutic strategy to damaged human cartilage cells. In a new study, published in the Journal of the American Chemical Society, the treatment activated the gene expression necessary to regenerate cartilage within just four hours.

And, after only three days, the human cells produced protein components needed for cartilage regeneration, something humans can’t do in adulthood.

The conceptual mechanisms of the dancing molecules work through cellular receptors located on the exterior of the cell membrane. These receptors are the gateways for thousands of compounds that run a myriad of processes in biology, but they exist in dense crowds constantly moving about on the cell membrane.

The dancing molecules quickly form synthetic nanofibers that move according to their chemical structure. They mimic the extracellular matrix of the surrounding tissue, and by ‘dancing’ these fibers can keep up with the movement of the cell receptors. By adding biological signaling receptors, the whole assemblage can functionally move and communicate with cells like natural biology.

“Cellular receptors constantly move around,” said Northwestern Professor of Materials Sciences Samuel Stupp, who led the study. “By making our molecules move, ‘dance’ or even leap temporarily out of these structures, known as supramolecular polymers, they are able to connect more effectively with receptors.”

The target of their work is the nearly 530 million people around the globe living with osteoarthritis, a degenerative disease in which tissues in joints break down over time, resulting in one of the most common forms of morbidity and disability.

“Current treatments aim to slow disease progression or postpone inevitable joint replacement,” Stupp said. “There are no regenerative options because humans do not have an inherent capacity to regenerate cartilage in adulthood.”

In the new study, Stupp and his team looked to the receptors for a specific protein critical for cartilage formation and maintenance. To target this receptor, the team developed a new circular peptide that mimics the bioactive signal of the protein, which is called transforming growth factor beta-1 (TGFb-1).

Northwestern U. Press then reported that the researchers incorporated this peptide into two different molecules that interact to form supramolecular polymers in water, each with the same ability to mimic TGFb-1...

“With the success of the study in human cartilage cells, we predict that cartilage regeneration will be greatly enhanced when used in highly translational pre-clinical models,” Stupp said. “It should develop into a novel bioactive material for regeneration of cartilage tissue in joints.”

“We are beginning to see the tremendous breadth of conditions that this fundamental discovery on ‘dancing molecules’ could apply to,” Stupp said. “Controlling supramolecular motion through chemical design appears to be a powerful tool to increase efficacy for a range of regenerative therapies.”"

sand battery

What Is a ‘Sand Battery’ 2023?

A “sand battery” is a high temperature thermal energy storage that uses sand or sand-like materials as its storage medium. It stores energy in sand as heat. 

Its main purpose is to work as a high-power and high-capacity reservoir for excess wind and solar energy. The energy is stored as heat, which can be used to heat homes, or to provide hot steam and high temperature process heat to industries that are often fossil-fuel dependent.

As the world shifts towards higher and higher renewables fraction in electricity production, the intermittent nature of these energy sources cause challenges to energy networks. The sand battery helps to ambitiously upscale renewables production by ensuring there’s always a way to benefit from clean energy, even if the surplus is massive.

The first commercial sand battery in the world is in a town called Kankaanpää, Western Finland. It is connected to a district heating network and heating residential and commercial buildings such as family homes and the municipal swimming pool. The district heating network is operated by an energy utility called Vatajankoski.

The term “sand battery” was introduced to grand audience by a BBC News story published the 5th of July 2022. The story was written by BBC News’ Environmental Correspondent Matt McGrath.

Frequently Asked Questions

What is the structure of your heat storage?

It is an insulated silo made of steel housing, filled with sand and heat transfer pipes. Additionally, equipment outside the storage is required, such as automation components, valves, a fan, and a heat exchanger or a steam generator.

How do you heat the sand?

With electricity from the grid or from local production, in both cases from fluctuating sources such as wind and solar. We charge it when clean and cheap electricity is available. The electrical energy is transferred to the heat storage using a closed loop air-pipe arrangement. Air is heated up using electrical resistors and circulated in the heat transfer piping.

How hot is the sand?

The maximum temperature in the Kankaanpää heat storage is about 600 degrees Celsius. However, the temperature may even be higher depending on customer needs. In practice, the maximum temperature of a sand-based heat storage is not limited by the properties of the storage medium, but by the heat resistance of the materials used in the construction and control of the storage.

How do you get heat out of the heat storage?

The heat storage is unloaded by blowing cool air through the pipes. It heats up as it passes through the storage, and it can be used for example to convert water into process steam or to heat district heating water in an air-to-water heat exchanger.

Why do you use sand?

Many solid materials, such as sand, can be heated to temperatures well above the boiling point of water. Sand-based heat storages can store several times the amount of energy that can be stored in a water tank of a similar size; this is thanks to the large temperature range allowed by the sand. So, it saves space and it allows versatile use in many industrial applications.

What kind of a sand you are using?

The heat storage is not very sensitive to sand grain size. We prefer high density, low-cost materials that are not from scarce sources. Someone else’s dirt could be our heat storage medium. We prefer to use materials that are not suitable for construction industry.

Does it matter what the grain size of the sand is?

Not much, we prefer to use those grain sizes that are not suitable for construction industry.

How is the heat storage insulated?

The heat storage is made of steel and insulated with standard, heat resistant insulating materials. The insulation is all around the heat storage between the outer steel layer and the inner one.

How long does the sand stay hot in the winter?

It can stay hot for months if needed, but the actual use case of the heat storage in Kankaanpää is to charge it in about 2-week cycles. The heat storage has its best range of use when it is charged and discharged 20 to 200 times per year, depending on the application.

Is the outer surface of the heat storage hot?

The surface of the storage is not hot, because the heat stays inside the storage—where it should be.

Can it store electricity?

Not as such, as it stores energy in the form of heat. The heat can be converted back to electricity using turbines like the ORC-turbine or a steam turbine. This requires additional investments to the turbine technology, and the conversion to electricity has inherent losses, thus complicating the economical side.

Is this a new technology?

Well, yes and no. The idea of heating sand to store energy is not new. Our way of doing things and commercializing it in large scale applications is.

Main Masterlist | Tony Stark Masterlist

The past three months have been interesting, to say the least. From being asked to interview none other than Iron Man himself about his research on nanotechnology to shadowing him for five months, it is a rollercoaster you never expected to get onto. Still, you do not want to get off because it's too much fun.

But that's not all because, during these months, you and Tony have also been building on the sexual tension that is palpable between the two of you. From semi-innocent flirting to not-so-innocent grinding on the dancefloor after a few drinks, it has all passed the revue, and it is like a rubber band that is about to snap. One more move, and it will snap, leaving both of you to lust after the other like never before.

Today, you're just observing Tony as he's working on his research, which would have been simple enough if it weren't for the fact that he's wearing a skintight shirt that exposes his broad shoulders, muscly, veiny, bulging biceps and forearms. His large, strong hands with long, skilled fingers have been the subject of your wet dreams. Your lip is pulled between your teeth as you look at him.

The shirt is pulled tight over his chest and abdomen, allowing you to drink in every inch of his muscles, which leads you to his narrow waist and thick legs covered in dark jeans that seem to hug his thick bulge and round butt perfectly, making you squeeze your legs together at the sight.

"Are you enjoying yourself over there, Sweets?" Tony asks with a quirked brow, and your eyes snap up to his as a flush appears on your cheeks at the fact you've been caught. You nod shyly, and a mischievous grin dances on Tony's lips as he walks over to where you're sitting on a table, which is the perfect spot to observe what he is doing.

"Did you like what you just saw? I'm sure you did because you've been clenching these delicious thighs and biting that perfect lip the entire time, huh? Don't think I haven't noticed it, Sweets; I can smell your arousal on the other side of the lab," he tells you in a low, rumbling voice that sends shivers down your spine.

"Y-yes, sir," you stammer out, the red color on your cheeks deepening when he stands before you. He moves forward as he places his hands on the table on either side of you, and you can't help but tremble as he's mere inches away from your face.

You accidentally knock something off the table as you shift your body a little to be more comfortable, and the heat on your cheeks now spreads from the tips of your ears down your chest as the embarrassment takes over completely. However, before you can think about it too much, Tony has cupped your face in his large hand, feeling the warmth radiating onto his long, calloused fingers.

"It's okay, Sweets. Nothing to be embarrassed about," he whispers before leaning forward, his lips kissing softly on the corner of your mouth. Your eyes flutter shut at the feeling of the softness of his lips on your face, a shuddering breath leaving your lips.

"A-are you sure?" you ask, and he nods.

"I'm sure. Whatever it is that you broke is nothing that I cannot replace; otherwise, it wouldn't be lying out here on the table," he says, and you can feel yourself already becoming calmer, the tension you were feeling earlier slowly replacing with need at the close proximity between you two.

Tony's hand drops down from your face to your bare thigh as he trails the tips of his fingers to the edge of your skirt, teasing you a little as a smile tugs at the corner of his mouth.

"You're perfect like this," he whispers in your ear, and you can't suppress the soft moan escaping your lips as he says those words. You have always enjoyed receiving praise, but hearing it from Tony does something to you that you have never considered. It only arouses you further.

"Did you think I wouldn't notice your skirt, Sweets? It barely covers your ass, so it's no wonder I could tell that you want me. You do want me, don't you?" Tony whispers between the kisses from your jaw to your throat until he reaches the sensitive spot beneath your ear.

You moan out a soft yes, and a small smile tugs at the corners of Tony's lips. Hearing that you want him just as much as he wants you has him twitching in his pants. He dares to move his fingers beneath the hem of your skirt. Just far enough to have a little taste of the skin hidden by the denim fabric, yet not enough to give you what you desperately want.

"Good girl," Tony tells you as you spread your thighs slightly, giving him the access you know he's been asking for without actually saying it. The flush on your cheeks returns as you pull your bottom lip between your teeth, trying to hide the fact that his praise is making your stomach flip and your skin feel like it's on fire.

Your breath hitches as you feel Tony's finger hook behind the elastic of your panties, allowing it to glide along the seam where your thigh meets your hip before moving away again just before he reaches the place you need him most. And once more, you're clenching around nothing because he loves being a tease.

A slight pout on your face has him chuckling before he leans in and kisses it away with a small peck, a smile taking its place instead when he pulls away. His hands slide under the hem of your shirt before pulling it off and over your head, revealing the light pink lingerie you're wearing underneath.

"This color looks beautiful on you, Sweets, but I know for sure it'll look even better on the floor," he says teasingly as he unclasps it, the fabric sliding down your arms and onto the floor effortlessly. His breath hitches in his throat as he sees what you've been hiding all this time, as two small, silver rings are adorning your nipples.

"Fuck," he whispers as he keeps staring for just a second too long, the blood in his body rushing to his cock at a rapid pace now that he notices them. Maybe you're not as innocent as he may have thought you to be, and he's practically drooling at the sight in front of him.

When he finally snaps back to reality, he grabs both your breasts, kneading them softly as he revels in the soft moans you let out. He cannot get enough of hearing them, though his ultimate goal is to have you screaming his name as loud as you possibly can, no matter who can hear it.

"Who would have thought that someone as sweet as you has her nipples pierced, hm? I bet they're nice and sensitive," he says as he softly tugs on the rings before playing with your nipples, your head falling back as the pleasure is increasingly growing. Tony takes the opportunity to suck some bruises onto your neck where it meets your shoulder, your fingers lacing into his hair.

Soft moans keep tumbling from your lips as the two of you stay like this for a while. Tony's lips on your neck have the arousal pooling in your panties again, and you're pretty sure there's a small puddle on the table where you're sitting at this point. From the teasing to the way he plays with your nipples and the praise he gives you, he is doing a damn good job of having you melt into a puddle.

"S-sir," you moan out eventually, the ache between your legs too much to handle at this point. Your clit is throbbing in anticipation as he pulls away, his gaze locking onto yours. The brown of his eyes is almost completely gone as lust has taken over.

"What's on your mind, Sweets?" Tony says sweetly, and you slip into the fuzzy headspace you always enjoy getting lost in.

"I need you," you whisper almost inaudibly, your eyes locked in a heated, lustful gaze.

"Yeah? Do you need Sir to play with that cute button between your legs? Or do you want me to slip my fingers in that undoubtedly tight, warm, and dripping pussy of yours?" he asks, and your eyes flutter closed at the thought of his fingers inside you, bringing you to your orgasm.

"Both," you tell him, and Tony can handle only so much before his restraint snaps. His fingers glide past your bare stomach down to your skirt, which has ridden up entirely from the rocking motions of your hips.

"What's your color, Sweets?" he asks, and your eyes slowly open before finding his. You may never have discussed the traffic light system with him before, but you still need to be aware of what he's talking about, and it gives you a warm sense of security.

"So, SO fucking green," you tell him with your eyes half-lidded, and Tony can't help but feel proud at the way you are already so fucked out, despite him barely touching you. It's a sight he knows he will never get enough of.

"Good girl," he says before pulling down your panties, the soaked fabric being put in the back pocket of his jeans to save for later. A soft moan slips past your lips again, and Tony can't stop reveling in the fact that you have a huge praise kink. He already knows he will make good use of that newfound knowledge.

"Does my girl like to be praised?" he asks, his fingers leisurely gliding through your folds to gather the slick between them, and he can tell you're increasingly getting wetter with his question. Your hands fly to his hair as he finds your clit, and you pull him close before moaning a yes into his ear.

His cock twitches in his pants at the way you're melting into a puddle under his touch, and he's reveling in every little moan and whimper slipping past your beautiful, soft, pink lips. The way the pad of his finger feels against your sensitive clit have you jolting each time they make contact, and you can't stop pulling on his dark brown locks as the pleasure inside you keeps building and building.

Almost as if he can sense it, Tony slips a finger into your pussy, being careful not to hurt you as he slides it in. Your head falls back as the pleasure takes over your body; the whimpers and moans from your lips only intensify when your orgasm creeps closer and closer until it washes over you with a scream of his name.

"That's it, Sweets, doing so well for me! You look fucking gorgeous when you cum," he groans out as you tremble, his fingers now making the filthiest, most delicious squelches as your arousal only grows. His fingers are like magic, and you only want more.

"Yeah?" you ask shyly when Tony's worked you through your orgasm, ensuring you don't crash from your high all of a sudden. A blush is adorning your face at the praise Tony has given you, and you can't stop yourself from wanting more of it and more of him.

"Fuck yes, 's the prettiest fuckin' sight I've ever seen, Sweets. Now I can't wait to see what you look like when you cum on my cock," he tells you, and the color on your cheeks deepens at the thought of Tony stretching you on his cock.

"Let's find out then, shall we?" you ask playfully, and Tony cannot say no to an offer like that. When you offer yourself up on a silver platter like that, he will definitely take his share of you. It would be stupid to deny himself something he so desperately wants, after all.

Before you know it, Tony is completely bare, and you can't stop staring at the monster of a cock that is standing at attention between his legs. The tip is already leaking pre-cum, and the blue veins running from the tip down his shaft don't go unnoticed by you, either. Finishing that with the way his balls look as they hang perfectly underneath it, and you know you're in love. With him. With his cock. With everything.

"Do you like what you see? If you want, you can give it a little touch first; it won't bite," Tony says as he steps closer, and you bite your lip as his cock bobs up and down with every step. You reach out on instinct, and you gasp at the way your hand can barely close around his girth.

"Hmm, look at that, Sweets. It's so big you can barely hold it all; are you sure it will all fit inside that tight pussy?" he teases you, and you nod immediately as you look up at him, your eyes torn away from his cock for the first time since he revealed it. Your hand moves up and down as he comes to stand between your legs, soft groans leaving his chest as you do so.

"God, you're perfect. Fuckin' perfect," he grits out as he thrusts carefully into your hand, trying not to stimulate himself too much before he cums without having even felt the warmth of your pussy yet. As he keeps praising you, your pussy clenches around nothing as you're aching for his cock to be put inside you, to slide home just the way you both want.

He can feel himself getting dangerously close to the edge, and before it's too late, he grips your wrist carefully, stopping your movements. You look up at him with concern, but he's quick to ease your mind.

"I was about to cum, Sweets, 'n' I don't want to yet," he tells you, and you nod. You let go of his cock, instead letting your hand dip down to play with his balls, which was a genius move as he moans loudly as you give them a gentle squeeze. He's very sensitive there, and you're dripping onto the table at the thought that it's you who does that to him.

"God, you're doin' so well for me, Sweets. Play with my balls like that; j-just roll 'em a bit," he whispers, and you do as he asks, pride swelling in your chest at his words. His cock throbs each time you squeeze them gently, rolling them in your hand, which barely fits around them. Even his balls are big in your hand, and Tony cannot get enough of the sight.

"That's enough for now," he tells you gently, and you let them go, already missing their weight in your hand. Despite their size, they were surprisingly comfortable in your hand, which is something you would never have thought.

As you wait for Tony to make the next move, he lifts his hand to tilt your head back a little, his finger touching your chin ever so slightly.

"I want you to know that if we continue, you can tell me to stop whenever you want. You can say yellow if you're uncomfortable and need to switch positions or red if you must stop altogether. Do you understand that?" Tony asks, and the care in his voice has your heart beat faster.

"Yes, sir," you whisper, and Tony rewards you with a small, soft kiss on your lips. It's not enough to get lost in, but enough to leave you wanting more, which is what he was going for.

"What's your color now?"

"Green, Sir. Very green," you tell him, and he nods. There are no signs of discomfort on your face, and Tony gives you a slight smirk as he grabs his cock this time, pumping it a few times before pulling you to the edge of the table and dragging his cock through your folds a few times. An obscenely loud moan escapes your lips as his tip rubs over your sensitive clit, and Tony feels himself throbbing in his hand.

"Lean back for me, Sweets," he tells you, and you do as he asks. The sight that unfolds has Tony squeezing himself at the base of his cock to ensure he doesn't cum yet. Your body looks like it's glowing, and your nipple piercings glisten beautifully in the lights of his lab, making him throb in his hand.

A groan escapes his lips as he lines himself up with your entrance, the warmth of your body already luring him in. The moment he pushes in, your soft, velvet walls envelop his tip, and he knows he's a goner, and he never wants to let you go. You're his.

"Fuck, you're squeezing me like a fuckin' slut; I can barely slide my cock in when you do that!" Tony groans out as you let out a string of broken moans at his words, your nails scratching his back to ground yourself as the pleasure builds quickly. He slowly rocks back and forth, your pussy stretching gradually around his girth.

"Oh, you like it when I talk dirty, don't you? When I call you out for what you are, just a slut who wants to be filled by my cock," Tony says with a mischievous smirk. As the words sink in with you, you let out a long, deep moan, unable to form a coherent thought at this point, but you're feeling so good that all you can do is let the pleasure take over now.

When he's about halfway in, he tears his gaze from his cock, sliding in and out of you to have a look at the way you're looking now. Eyes half-lidded and completely dark with lust, a flush on your cheeks, and your mouth slightly parted— a perfect sight for Tony to enjoy.

"Look at me, Sweets; look in my eyes and answer me. Does my filthy slut like it when Sir talks dirty to her? When I tell you that I'm about to fuck you dumb until you're nothing but a cockdrunk mess for me?" he asks you, and all you can do is nod right now. His words are nestling deep into your brain, and your nipples pebble at the thoughts he's planting.

"You're perfect for me, Sweets. Doin' so well for me right now," he then praises you, and a flush appears on your cheeks from the sudden change in tone. He keeps carefully sliding in deeper, ensuring you have enough time to adjust to his length and girth as he does.

"Color?" he asks when a soft whimper suddenly tumbles from your lips. The last thing he wants is to cause you discomfort, and he will ensure you are given the chance to speak up if needed. Even though it takes you quite a long moment to gather your thoughts, you finally manage to tell him you're good to go.

"M so fucking green," you tell him with a sudden boost of confidence, and his mouth curls into a knowing smile. Now that he's satisfied with your answer, he starts to thrust in deeper, and the second he hits your sweet spot, your head falls back, and you moan loudly, your nipples even perking up at the sensation.

"Hmm, does my girl like it when Sir is this fucking deep? I bet you do, huh?" he asks, and you nod in response. It feels incredible, and you want more of it. You want Tony to stretch you and fuck you until you can't walk anymore. You want all of that and more.

"Y-yes!" you tell him, and he almost pulls out before slamming his cock deep into you, pulling the most delicious scream for your chest as you can't hold it back.

"Scream for me, scream my fucking name as I fuck you," Tony says through gritted teeth. He thrusts his cock deeper into you, and you are sure you can almost feel him in your throat with how deep he fucks you. He hooks his hands behind your knees before lifting them and practically folding you in half on the table.

When you're comfortable in your new position, he leans in, pressing his chest against yours and placing your ankles on his shoulders. In this position, he can truly fuck you deep and hard, and your back arches against him as the pleasure inside you builds even higher this way.

"God, look at you; you like being bent in half, don't you? I can just put you in whichever position and fuck you however I want, can't I?" he says, but you're too far gone even to realize what he's saying. The moans that are coming out are practically endless. Despite that, he can feel you gripping onto his cock like a vice, sucking him deeper with each thrust.

"My little slut enjoys it when I fuck her stupid, huh? Yeah, that's why you're moaning for me. And here I thought you were just an innocent little girl. Oh no, you're a fucking slut who likes to be told what to do, aren't you?" he asks, the table now shaking and more items falling off from the intense rocking motions.

"Y-yes! M your slut!" is all you can bring out as he sets a pace that has you seeing stars. The way his balls smack against your ass makes a sound that has you blushing intensely, and the squelching sound your pussy makes with every thrust has you only getting wetter.

"Can't wait to stuff you full with my cum, then watch it drip out before I fuck it right back in with my cock," he tells you, and it makes you feel like you're floating as it sets your veins on fire at the same time, you have never felt this dirty yet so good at the same time.

"Yes! Please fuck your cum in me," you moan out before pulling him towards you by his hair, your lips colliding in a bruising kiss, your tongues fighting for dominance. The combination of everything together has you moaning into his mouth as he keeps fucking you, and before you know it, you're cumming hard.

With a scream of his name, you squirt all over his cock, legs, and the floor, your legs trembling uncontrollably and your vision going white around the edges for a moment. Tony keeps praising you as he fucks you through it, and you're clenching down on his cock as you cum, making him unable to hold out any longer as well.

"Yes, yes, YES! Oh god, you fucking squirted like a perfect girl! I can't believe how lucky I am right now, Sweets! Getting squirted on by my girl feels so fucking amazing!" he pants out, and it does not go unnoticed by you that he calls you his girl.

"M yours, m all yours, Tony," you say between ragged breaths, and with those words, he has reached his orgasm as well, as he shoots every last drop of his cum into your tight heat. He can't stop moaning your name over and over again as he nuzzles his face into your neck, needing to have you as close as physically possible.

"You're absolutely amazing, Sweets—an amazing woman, an amazing journalist, and, above all, my amazing girl. Because I'm not letting you go after this," he whispers against your neck, and you agree as you wrap your hands around his neck.

"All yours," you tell him. The two of you stay like that for a few more moments before Tony has to pull out, his cock too sensitive to remain inside you any longer.

"Shall we take a bath together?" he offers, and you nod. After throwing on Tony's t-shirt, which is about three or four sizes too large and practically a dress on you, he walks you to the elevator that goes right to his penthouse. He just pulled on his jeans without bothering to button them; he'll be pulling them off shortly anyway.

Thankfully, the bath doesn't take long to be drawn and ready. You let out a soft groan as you sink in the hot water, allowing your sore muscles to relax. Tony follows you soon after, having gotten two bottles of water and some fruit to enjoy while you're in the bath.

"Y'know, I was trying to be gentle with you, but as soon as I figured out you're just a filthy slut like me, I couldn't hold back," he whispers in your ear as you're straddling his lap, his cock trapped between your bodies. A lopsided grin lies on his lips as he looks at the blush developing on your cheeks, and he wants to make you blush even more because it has quickly become his favorite color. 

Instead of answering, you lean forward to capture his lips with yours as your fingers glide into his messy curls to pull him closer. The kiss starts slow as you discover the feeling of his lips sliding over yours, but as time goes on, your tongues begin to mingle, too. The taste of something exciting and new invades all your senses, and you're hooked, only wanting more of him and how he makes you feel.

When you finally pull away, there's a smile on your face, but Tony can tell it's not reaching your eyes. The smile he's been craving to see isn't fully there, and his brows are furrowed at the realization.

"What's on your mind, Sweet Girl?" Tony asks, and you drop your gaze as the embarrassment replaces the butterflies that were going crazy in your stomach.

"S nothing, Tony," you whisper, but he knows that's not true. If it has you feeling like this, there is probably something wrong, and he wants to learn all about it so he can fix it, no matter what he would have to do for you. He'd fly to the moon and back if that's what you wanted him to do, no questions asked.

"I may not have known you long, but your mood doesn't turn from one end to the other without a reason. I respect it if you don't want to talk about it, but I also think it will make you feel better if you do," Tony tells you before he gives a soft kiss on your forehead.

With a soft sigh, you plant your hands on both sides of his arc reactor, and the slight hum coming from it makes you feel a little more at ease. It's barely noticeable, but it's enough to calm your nerves, and you decide to tell him what's exactly on your mind. When your eyes lock onto him, you can feel tears burning at the corners of them, a bit afraid of what his response will be.

"I-Is this just a one-time thing? Because if it is, I'd like to know now so I can prepare myself for the heartbreak later," you whisper, the tears spilling over your cheeks. You've been through this too many times to count, and you do not want to be on the receiving end of yet another rejection.

"What? Of course not, Sweets. When I told you you're mine earlier, I meant it. I mean it! We've built a connection over the past three months that I have not felt with anyone in a long time, and I definitely do not consider this a one-time thing. I'm so fuckin' in love with you, I would be crazy to let you go now," he says, and your eyes grow wide as saucers at his confession.

"Y-you're in love with me?" you stammer, the butterflies in your stomach immediately returning at his confession.

"I am, Sweets. I've never met anyone as smart, caring, and sweet as you. And you're very easy on the eyes, too," he says with a wink, making you smile.

"I wouldn't have had sex with you if I didn't think it would go anywhere after today, Baby. You're too special for me to let go, and I want to explore whatever this is between us. But most of all, I'd like to kiss you right now because these lips have been calling my name the entire time," he says as he leans in, capturing your mouth with his.

When you pull away, you give him a soft smile before nuzzling your face into his neck, his arms wrapped around your waist as he pulls you closer until you doze off for a short nap. When you wake up, Tony wipes some hair out of your face, and you're met with a gentle smile on his face.

"How're you feeling, Sweets?" Tony asks before popping a raspberry in his mouth, the sweet yet tangy taste invading his mouth as he listens to what you have to say.

"Good. Tired- but good," you tell him with a dopey smile. You're fully relaxed as you sit in the bath with the man you've fallen in love with. And now that you're his, life couldn't be any better.

"I'm glad. And for the record, I meant what I said earlier. I'm not letting you go after this, especially after I've gotten my slice of heaven earlier," he tells you, and you let yourself melt against his body.

"I know, and I don't want to go, Tony. I want to stay in our slice of heaven for as long as you'll have me," you tell him, sealing the deal with a soft, gentle kiss. After that, you let out a small sigh of relief before Tony hand-feeds you more fruits, and you've never been happier in your life than you are now.

What started as nothing more than another job for you has developed into a new chapter of your life, and you're excited to see where this story will go from here on out.
