Claiming Professor Grace Flayer

A second or so of silence passes. You feel Miss Flayer staring at you intensely before her form deflates ever so slightly as she releases a silent, almost invisible sigh.

"Mister Ring," she says, her tone underlined with professional neutrality. Yet, you just barely sense a tinge of something else beneath the surface. "May I know what in your phone was so important that you didn't pay attention to the lecture?"

"It was nothing, Professor," you reply. "I'm sorry about that."

Miss Flayer gives you a slightly unpleasant expression. "Mister Ring, I thought I was clear during the first lecture. There is a line of respect to upkeep in here. If you have something urgent, I'm not holding you in the classroom. You are an adult, and I expect that you can make a sensible choice. Am I wrong?" her brow raises. She steps from foot to foot, and you get a brief view of how her 36-inch hips sway as she readjusts herself. The shirt on her chest shuffles slightly as well, and the outline of her breasts becomes more pronounced. She could really use a couple enhancements, you ponder for a split second. The thought of her and Professor Kay standing side-by-side, like the busty teachers you want them to turn into, makes your dick throb.

"No, Professor," you answer, but at the same time, you cannot help but let your imagination run wild. You can already imagine the woman in front of you staring at you with amazement, fingering herself while her assets fill out, waiting for you to spear her to heaven and back.

"I do my best to respect your rights a a student. All I ask in return is a bit of respect for what I do as a professor," Miss Flayer eyes you briefly, hands under her chest. "Do you understand, Mister Ring?"

"Yes, Professor."

A sense of bitterness bites your throat. You hate this type of people. Some professors, in particular, were a perfect representation of this small-mindedness. You understood that they had work and spare time and that sometimes, they needed to take that spare time to form interesting lectures. And you'd understand her reaction if you were running around the class or being loud, but seriously? Nagging about quietly using a phone in class? It was almost like she was trying to find a nitpick.

Your absent-minded ponders are immediately cut out as Miss Flayer's voice sharpens, "Mister Ring, where are you looking?" the brunette woman frowns, hands crossing over her chest.

Your eyes snap upward when you realize you've been staring at the X on her right breast for at least a few seconds. Seeing the woman's upset expression, you can't help but feel a bit of warmth bite your ears.

"I'm sorry, Professor," you say, trying to maintain a composed look. "I was just lost in thought."

"So I see," her frown deepens. She remains silent beyond that, but her brown eyes scrutinize you briefly, and you can't help but notice that she makes the shortest of pauses on your crotch. Some emotion crosses her face before you see her cheeks flush very slightly.

Following her gaze, you notice a tent in your pants, made by your penis no doubt. It throbs with every beat of your heart, and you can't help but feel it's not only your imagination that made it that way.

Looking back at the woman in front of you, you feel a tiny smirk enter your face. Her face is progressively redder near her ears.

"Miss Flayer," you speak up, taking a tiny step toward her. "I do have a certain problem, and I hope you can fix it for me," you say, looking her dead in the eye as your fingers make it into your pants.

As your trousers and underwear drop, you hear Miss Flayer begin protesting. Her voice rises briefly before dying out, her eyes going wide at your member. There is a visible twitch in her pose, and as you raise your phone, you confirm that her horny gauge just jumped to 80. You smile, your cock standing more proudly by the second.

The professor almost immediately approaches you, her hips swaying tantalizingly as she closes the distance slowly. Every step she takes is deliberate, and you can already see that her hands are trembling faintly, reflecting her feverish state. The slightly crazed look in her eyes focused on your penis makes her look like a sex-starved nympho.

...nympho...

The word makes an idea pop up in your head. With a single word, you stop Miss Flayer, who gives you a questioning look full of need. You step toward the door to the classroom, making sure to lock it. Then, you order her simply.

"Undress."

Her hands move like she was waiting for that command. In less than a second, her shirt is removed, exposing the lacy black bra underneath. Miss Flayer then stands up to take her skirt off. As the garment falls, you notice matching panties. Despite the color, you can make out a damp spot on them, the evidence of her horny gauge.

"On your knees," you say, to which the woman immediately plops into position. Her hands rest on her kneecaps as she looks at you intensely, horny yet obedient as per her trance.

With a quick motion, you fish out your phone and open Miss Flayer's profile.

A surge of possibilities flows through your head. One tells you to make her subservient to you with a hypnotic trance like you did to Alex. Another speaks with clear intent, telling you to demean and humiliate her over the nonsensical rules she imposes.

However, there is another thing you want to try.

<Grace Flayer's arousal goes down slower than normal during sexual acts and builds up quicker when near John Ring.>

The condition is placed successfully as you see it added to her profile. As per your additional description, it is shortened to a simple word: nymphomaniac. A surge of warmth makes your cock throb, and it feels harder than ever. There is an immediate synergy between Miss Flayer's condition and your own. A pang of satisfaction fires in your stomach.

"Go on, you know what to do," you beckon to the woman, who immediately shuffles on all fours toward you.

She grabs your cock tenderly with one hand, striking its length. You can feel the warmth of her hand meet the searing heat of your skin, and your shaft pulses with every slow stroke she makes.

Focusing your phone on the woman, you consider what to change about her. In sincerity, you want to give her a similar condition to Professor Kay. At the same time, you don't want to make it the same, even though the prospect of her body filling out with every equation you get right is hot.

Then, it hits you, almost as strongly as Miss Flayer taking your cock in her wet mouth. There is a middle ground you can go down on. With an almost devilish grin, you spend the coins required to get an upgrade in the amount of conditions and begin writing.

<A configurable percent of all growth on Grace Flayer occurs instantly, and the remaining percentage is applied gradually over a week.>

However, as you append the condition, an error occurs, telling you that you need at least level 3 of the Condition ability for this to be possible. With the ones you have + the ones you hadn't yet collected for registering Erin and Professor Grace, you'd barely be able to get the second level. A faint groan escapes your mouth, followed by a moan as you feel Miss Flayer work the helmet of your dick with her mouth. You can tell she's adept at this, as she does not miss a spot.

You grab her head with a hand. Stroking her hair, you feel the woman under you shudder with need. One of her hands is in her panties, pleasuring her as she moans in rhythm to her head pumping down your cock. Giving her all your focus, you suddenly thrust your hips, making her nose touch your pubes.

"Miss Flayer, I'm going to cum!" you announce, moaning as your cock throbs furiously. Then, you release, painting her mouth and throat with your seed.

You feel your stamina leave you for the shortest of moments as Miss Flayer takes your penis out of her mouth and swallows audibly. Then, any sense of fatigue fades as your cock hardens instantly, glistening with her saliva and the remnants of your cum.

"You're not done? Good," she says sultrily, a happy emotion lurking in her eyes as she inches closer to your cock again. "Because I want this deep~ in me, Mister Ring," she almost laughs, suckling on its length and making a nearly obscene slurping sound. "All~ of it."

"Miss Flayer--"

"Call me Grace, handsome," she hushes you in an instant before licking your tool.

"You're so beautiful like this, Grace," you blurt out with a smile. "Get me off again, and I'll show you what I can do."

"Mmm taking control? Don't mind if I do," she replies before clasping her mouth on your shaft again.

As Grace continues sucking you, you focus your mind on your predicament just now. It feels annoying that the condition that would work perfectly for her is gated behind an upgrade you couldn't get even if you cashed out your rewards.

However, as you glance at your phone screen, you notice a small button appear next to the 'append' button. A small description says that it's a way for you to lower your condition's demands so that it can be applied to the app's current abilities, including if you bought some new function. Without waiting, you click it and are greeted with a new condition.

<25% of all growth on Grace Flayer occurs instantly, and the remaining percentage is applied gradually over a week. This does not apply to Temporary Transformations and cannot crit.

Requirements: Condition lvl. 2 (purchasable), Transformation lvl. 2 (owned)>

You accept it like this. It's honestly much better than you expected. Your tokens trickle down to a clean zero, but you don't mind. You steady your hold.

Aiming your phone at Grace again, you ponder what to do first. 21 inches are available for use with normal Transformation, and another 15 with Temporary one. That is a lot of growth she can take, and you already mentally plan out what you want to do.

You turn the awareness on before you begin, depositing 6 inches into her hips and 4 into her thighs with the temporary inches.

You see her derriere plump out gradually as her head moves across your shaft. Grace's speed slows and then comes to a halt as her hands go to inspect her posterior, feeling it expand under her fingers. Her eyes widen, and the arousal in her gaze seems to overflow.

"W-What...?" she looks at you, eyes overcome with surprise. "What did you--"

"Hush," you silence her, a hand forcing her head back onto your cock. "Just enjoy it, Grace."

You watch with amazement as her ass plumps out more, surpassing 40 inches in size. No matter how many times you see the expansion unfold, it never bores you. Grace's skin begins overflowing her panties which start to visibly dig into her as the growth slowly finishes, 42 inches of delightful ass sitting on 34-inch thighs. Your heart beats with power, and your cock throbs at the sight. You barely even have the time to tell Grace you're cumming again.

As she takes your second load in her mouth, she greedily gulps it down. The need in her motion is evident, and as she swallows the last drop, she gasps at you, showing you her empty mouth.

"Good," you say, getting a hold of your dick and smearing its tip on her cheek. "Go to your desk, Grace."

If she were any faster, you swear she'd fly. Grace lifts herself almost like she has a springboard under her knees. She saunters to her destination seductively, giving you a hungry look. You, in turn, are amazed by her posterior struggling against her panties, the obvious skindentation all too arousing an image.

You lift your phone and see her questioning expression. Without waiting for her to voice her thoughts, you apply the remaining inches right where Grace needs them the most.

"Oh!" her moan is obvious as she twitches in place. Her attention is immediately turned to her front as her breasts twitch. Grace's breasts immediately swell, going from a low B to a high B-cup. Within seconds, they reach a mid C-cup, stopping their expansion there. In sincerity, while they do bulge out of the cups, it's not that obvious.

"D-Did you do that?" Grace's voice falters as she looks at you. Her form shudders as you come over and get a hand over her posterior, fondling the abundant skin.

"Do you like it?" you ask, kneading her flesh with some ****. Your cock is sandwiched between her asscheeks, and you can feel heat beaming from the brunette.

She doesn't answer you for a moment, her hands going to her breasts. "I love this!" she says cheerfully, her fingers sinking into her skin.

"Good. There's more where that came from, Grace," you say, inching closer to her face. "Because from now on, you're mine."

Her face flusters as she realizes what your words mean. However, without a word, she pushes her posterior against you, encouraging you to take action.

You slip a finger under her panties, your other hand guiding your cock below her snatch. The heat beaming through the cloth is as prominent as the wetness that it cannot hold, the professor's love juices seeping onto your shaft. With a quick tug, you take the garment down, teasing her for a second or so before your cock enters.

It feels different within Grace than any other girl you've fucked so far. Maybe it's because because of the condition that turns her almost insatiable, but the wetness of her cunt is incomparable to any other. It's like a torrent that tries to drown your cock. Likewise, the heat feels like she wants to melt your tool. The prodigious pussy juice makes it easy to slip inside, and you sheath yourself within her in a single motion.

A moan escapes Grace's mouth. It is filled with need and a happy tone of arousal, evident in her body shuddering and twitching. As you pull out partway, you are suddenly met with her own motions as the brunette teacher slams her meaty hips against yours.

You grasp at her posterior, holding it with a vice-like grip as you hasten your moves. Grace moans the world in guttural sounds as she cums almost immediately. However, her motions hardly abate, her hands gripping the desk for dear life as you relentlessly pound her from behind. Her tits brush on the desk through the black bra, and you can imagine the extra stimulation that gives her.

"Holy shit," you say with a gasp, your every move stronger. "I'm gonna cum, Grace!"

She responds with an animalistic moan, her nails scratching the wood as she also pumps her hips faster.

With a brief shout, you slam the final time into the professor, your cock exploding deep inside. Your balls feel like they just dumped double the usual load despite what's happened so far.

The second or so of calm persists as you can see Grace's form slowly rising on her elbows. She turns to you, her eyes full of lustful spirit that has yet to leave her. Her face is red and sweaty, and her mouth is curved in a silly smile.

You respond in kind, slapping her ass. With a moan, the brunette before you shakes it, making the delightful mass ripple. Your cock, still buried inside, is stimulated further as her insides massage you.

"What's next, John?" Grace asks, her panting slowly abating. By now, all boundaries are forgotten. You aren't a teacher and student anymore, but a pair of lustful, insatiable lovers.

You exit her snatch, and a small trickle of cum follows. Taking a step back, you position yourself on a chair and wordlessly beckon her over.

Grace immediately understands your intention and skitters to you. Within a second or so, she sits on your legs, her arms draped over you as your breaths mix. Your cock pushes against her stomach, twitching periodically as her skin moves with every breath. There is an untold, electrical connection between you as your lips find one another's. The contact persists for a few seconds, and you take this time to cup her breasts. They almost spill out of her bra, which gives you an idea.

"Your time to work, Grace," you say huskily as you dislodge from her lips.

She gives you a simple, sultry smile before standing up slightly. As she positions herself over your cock, intent to take you in, you point her phone at her. Without thinking much, you deposit 12 inches into her breasts, 5 into her hips, and 4 into her thighs.

The reaction is immediate. Just before your cock enters Grace's pussy, you see her body twitch, and she releases a short moan. Her breasts immediately bulge out more, gradually growing to mid D-cup size. You cup them in your hands, and as they spill over the top more and more, you pull at the bra, releasing the small, erect nipples. Tweaking them in your fingers, you sense Grace vibrating with need all over, her mouth releasing another gasping moan.

She descends on your shaft, taking you in. It feels less restrictive than before, yet the intense stimulation from before is the same. Your cum, mixed with the professor's juices, lubricates your shaft easily, and the motion is finished within a moment. As Grace sits on you, she grinds her hips, now 43 inches in size, every subtle movement causing ripples to travel across her abundant flesh. The thought of her becoming even curvier over the next week is enough to make you begin pumping your hips.

Then, you decide to finally do what you were supposed to do a while ago. Activating Measurement Vision, you notice the blue marker appear on her right teat. Without waiting for anything, you fondle her tit, and the X disappears.

Initially, nothing happens. However, as Grace jumps atop you, you sense it. She's getting heavier. No, rather than just heavier, it's another thing. She's growing as she's riding you.

It's not a lot. She gained just an inch in height, making her 5' 10", but that's enough to be feelable. More than that, however, you notice that all other assets the woman sports also increased in size. Her breasts grew to a high D-cup, and her waist, hips, and thighs each increased by an inch.

You focus on her hips. The red marker is also visible, moving slowly before you touch it. However, unlike with the blue one, nothing happens. Focusing on Grace as a whole again, you see no notable changes. Her measurements remain the same. But you decide to push the thought off for now.

Grace gasps needily, nearly releasing bursts of steam from her lungs. She lifts herself quickly and immediately slams down and then repeats the motion. She looks you deep in the eyes, the need and growing affection evident. Her hands are tightly on your shoulders as she steadies herself while her hips move with more vigor by the second.

"God, oh god," she gasps, her head lowering. "I'm gonna cum, I'm gonna cum so hard, John," she chants your name like a spell.

"You're so hot, Grace, I'm gonna cum in you," you respond, nibbling her lips with your own.

"Yes, yes, yes!" she breaks a smile. Her eyes are overcome with a happy feeling. "Cum in me, cum, cum, cummmmmmm!" her voice breaks out into a shout as she suddenly convulses.

Her cunt clenching around you is enough to send you over the edge.

"Take my cum, Grace!" you gasp at her, your hands going to her hips and slamming her down on you with full ****. The moment this happens, your cock explodes deep within her.

The climax seems to prolong into eternity. Your cock pumps once, then twice, and finally, it finishes as the third solid pump of cum is deposited into the professor's needy snatch. Grace's insides welcome every last drop, continuing to massage you with their wet embrace.

It takes you both a few seconds to catch a breath. Grace slowly lifts herself, distancing herself from you slightly. Need in her is still there, as evidenced by her continuing to grind on you for some seconds, but she slows her moves, taking in the moment of calm.

"Amazing," she says, her lustful tone making your heart pound. The affectionate gaze of her brown eyes seems to underscore her need. "But I need more," she demands, slowly moving again. Her hot breath brushes on your mouth as she leans in closer, resuming her movement.

Your hands find their way to Grace's hips. Fondling her asscheeks for a prolonged moment, you suddenly grasp at the prominent assets before stopping the woman. As she gives you a quizzical look, you begin ascending from your position. The brunette professor reads your intentions instantly, her legs clenching around your hips.

You lay Grace down on the desk. Whatever documents were layered there were whisked away with a quick motion, flowing to the ground. A faint clattering noise is released by a stapler and a few pens, but neither of you cares.

You spread her legs wide before exiting her snatch. Grace gets a hold of her feet, showing you just how much she can stretch. This wasn't precisely your intention, but you weren't going to complain. With a quick motion, you rustle in your position, teasing her snatch. The long moment of calm is spent simply looking at one another. Grace's hair has become undone, the fluff of brown hair sprawled under her head. You find it both fulfilling and almost comical that the same teacher who nagged on you no more than fifteen minutes ago was now in this position, her cunt full of your seed yet still begging for more.

You slowly lower your cock. Relishing in watching Grace's entire form twitch and spasm as your every inch enters her, you deliberately move slowly. She gasps, the motions not enough to elicit a moan, but does not tell you to speed up. You can feel her cunt pulsing, the vaginal walls milking you with every second. Then, you pull out and thrust back in, again and again and again.

Grace moans with abandon every time you slam balls deep inside her. Her tits, just barely even covered by her bra, swing with every motion, ripples traveling on their surfaces. The same can be said about her huge ass and abundant thighs. Her eyes are glossing over, tears of pleasure escaping as she climaxes under the stimulation. You pound relentlessly, speeding up.

The desk is creaking as it's being strained with sideways motion, but the sound barely enters your ears. The only sounds you're interested in are the slaps echoing in the classroom with every second, and the delightful moans Grace releases.

You don't even know when you cum. All you know is that your motions do not stop in the slightest, even as your cock is spraying her insides with your thick cream. Grace doesn't even seem aware of your climax, lost in her own orgasm. Her legs spasm, but she still holds her feet, allowing maximum access as you finally feel your cock begin to peter out. This must mean that the nymphomaniac is starting to feel tired as well.

You exit Grace's pussy and lean on the desk. Your shirt now has prominent, dark spots on it, but as you look at your professor, it's all worth it.

Grace slowly relaxes in her position. Her breathing is labored, and there is a mist over her eyes. She looks at you with longing, still wanting more. Yet, she releases a prolonged breath and lifts herself to a sitting position. Her big tits jiggle and wobble with every motion, and she does not hesitate to take a few seconds to fondle them. She moans briefly, her entire body shuddering as she explores her newfound curves. You can tell she's enjoying it.

But then, she looks at you. There is a moment of silence as you reciprocate.

"How do you like it, Grace?" you break the charm, studying her expressions.

"This is amazing," she says as she continues to cup her breasts. "You can do this...?" she gives you a quizzical look. You can tell she's just barely fighting the urge to shower you with questions.

"And much more," you answer, straightening up and taking a step closer. Grace does not even flinch as you cup her ass. Rather, you can see her lean into your touch, her eyes fluttering briefly before she closes them, relishing in the sensation. "You know why, don't you?"

"...because I'm yours," she murmurs, her eyelids fluttering.

Your heart throbs. Power surges through your veins, seeing the submissiveness appear in Grace's brown eyes. She's accepting her role as your woman, completely willingly at it. You trace the line of her chin, feeling her give in immediately with a hum.

"...I want more," she says dreamily, her mouth seeking yours. Her hands are still tweaking her nipples. "I want so much more."

You return the sensual kiss, feeling her grind against you. Your cock rubs between Grace's thighs, and you can feel your own cum drip on it. If you so much as thrust upward, you'll enter. However, before you make up your mind to do it, the brunette shuffles away from you.

"But we can't continue. Not now," Grace sighs at your puzzled expression. The need in her eyes is clear, and there is a resignation in how she struggles to put her panties on. "I have classes to attend to soon, John. I imagine the same is true for you."

You release a brief sigh before nodding. You didn't expect this, but it doesn't mean you're dissatisfied. This was easily the most intense sex you've ever had, and looking at Grace struggle to contain her new assets is going to become a new core memory. However, you know she's right. It's one thing if you have fun in private, but if you're caught like this, it could cause problems. Maybe not with women, but it's a different story with men. You don't really know how or even if the app affects men. That should probably go on a list of things to be checked soon.

You go to pick up your pants and underwear. Putting them on, you can't help but frown at the sensation of your dick, still hard, pushing against the fabric. Then, you steal a glance at Grace.

Releasing the hold of her tits, she pulls at her bra, forcing it over her nipples. It's a struggle, and you see her bra dig into her shoulders slightly. With every breath, you imagine that the garment is fighting for its dear life.

"*Sigh* Looks like I'll need to look into some new clothes," she sighs, but contrary to her resigned tone, there is a smile on her face.

"I'd look a few sizes ahead if I were you," you suggest almost off-handedly, reminding yourself of what's going to happen to her during the week.

"...how many ahead?" she raises a brow at you.

"How many do you want?"

The brunette giggles at your answer, realizing what you mean.

Grace finds and wears her skirt, but the increase in her curvatures is obvious, as she struggles to even make a causal step before the cloth stops her. As she covers her chest with a shirt, her enlarged breasts are also visible. She prods them with a finger before doing the last checkups on her state. The sweat on her face is swiped away already, and while her skin is still red, she's already calming down. Her breathing is labored but stable. If you didn't know what she was doing, you could be fooled to say she was jogging beforehand.

Grace struts closer to you. With the additional inch in height, she now has to look even further down at you. However, you notice the sultriness of the smile she gives you.

"Well, Mister Ring," she starts before leaning in and whispering in your ear. "You should give me a call sometime. I have Wednesdays off. Come to my place and we can properly break a bed~," she husks in your ear before giving your earlobe a gentle lick. That startles you, and you barely even feel Grace slip something in your hand.

Then, she gives you a long, sensual kiss. Her tongue wrestles yours for some seconds before she dislodges with an obscene sound. The strand of saliva connecting your mouths breaks off, marking a stain on her shirt.

"Time to go, John," she says. "I'll see you around."

...

Standing in the empty corridor, you can't help but still process in full what just happened. As you do that, you finally feel the snippet of paper between your fingers. Unfolding it, you notice it to be Grace's number, as well as an address in the city - hers, no doubt. Hell, there's even the code to the entry phone. You figure that she must've written it down when you were dressing.

You release a heavy sigh. Finally, you can feel the wave of arousal diminishing. Your mind clears more by the second, and you decide to go to the next class. As you do so, you fire up your phone.

As you skim past your feed on YouTube, your phone suddenly vibrates, and a message prompt appears on the top of the screen. You immediately notice the name.

It's a message from Sophia.
