*************

The morning sun cast its warming rays through the window blinds covering Michelle's living room window. The light danced around the knocked-over furniture, bouncing off of the empty wine bottles and beer cans.

Kate grabbed one of the half-crushed cans and studied her own reflection on it. Despite last night's wild party her hair had emerged perfect like nothing had happened. Her makeup was a bit worn but due to her natural beauty it hardly mattered. Thinking back to last night she blew a kiss at her reflection. She wondered how Mike would have reacted if he was the one to catch it.

"Are you actually going to clean it up or are you just making out with it?"

Kate turned her head slightly and looked at Michelle. Michelle hadn't been as fortunate as Kate; the oceanic levels of wine hadn't treated her as gently. While Kate was cleaning up the mess, Michelle was lying on her couch, covered by a wool quilt and tightly hugging a plastic bucket. She shifted under her quilt and bobbed her head down over the bucket, making gagging noises.

"You're welcome to help anytime", Kate answered mockingly.

Michelle didn't raise her head but flipped Kate off instead. Kate chuckled with schadenfreude and tossed the can into a garbage bag. She stood up to collect the rest of the cans littered around the room like autumn leaves. Michelle raised her head from the bucket.

"I can't believe what you made me do last night."

Kate feigned innocence in her voice: "Made you do what exactly?"

"Don't you go all Miss Innocent on me", Michelle sneered, "you threw me at Mike like I was your personal attack dog."

"To be perfectly frank", Kate replied, "you did all that on your own, and with great gusto judging by how panicked he was afterwards, I might add."

"I might've done that if he really was single but going after a friend's boyfriend is a new low for me", Michelle threw back.

"So you admit you would've gone all the way if Anna was out of the picture?" Kate asked raising her eyebrow questioningly.

"Yes! Well... maybe. But that wasn't the case!" Michelle tuned up her voice, "I was wasted off my ass! I wasn't thinking straight!"

"Girl, I saw how you were devouring him with you gaze when I retreated to the kitchen with Anna", Kate said turning back to the cans, "and I really don't blame you. Alcohol doesn't make you do stupid things, it brings out the real you. And the real Michelle wanted Mike to rock her wine-hazed world. Unfortunately you keep that Michelle, that strong, aggressive and determined Michelle, in chains, while the care-free and only casually slutty Michelle is allowed to reign free."

Michelle's objection was cut short by another spelunking expedition into the depths of her bucket, accompanied by hangover gagging.

"I, on the other hand", Kate continued, "am more strategically minded. You charged pussy-first into battle and were rejected. Don't worry, the same would've happened to me if I had tried that. The key to victory here is remaining cunning. I need to wear him down subtly; a flirty joke here, a little teasing there, and boom! I'm the one nose-kissing Mike at parties. I'm the one walking hand in hand with him on the street. I'm the one in his bed every night."

Michelle rose again and looked at Kate with slight confusion.

"Nose-kissing? Walking hand in hand? I thought you just wanted to fuck him."

Kate looked at her friend with genuine irritation.

"Do you really think I'm that big a slut? I don't want to just sleep with him, I want to be with him!"

"Guys like Mike are like lightning in a bottle", she added, "good-looking, smart, funny and boyfriend material. He doesn't realize it yet, but Anna's not the right one for him. Anna's sweet, sure, but she's also plain, boring and an all-around snorefest to be with. We've talked a few times and based on her description of her sexual encounters I can tell she's not much fun in bed either."

"No, Mike should be with me. He has the mind for natural phenomena in matter, whereas I have the mind for human behavior. He enjoys the mathematical side of chess, I enjoy mind games that come along with it. He has a great body; pecs and biceps. I have a big pair of breasts, an ass and hips. We complement each other like great couples do."

"And what about Anna? She's sweet, cute and would make for a good wife for someone as uninteresting. But literature, honestly? Or that she couldn't solve a sudoku to save her life? Or the fact that she has no means to keep her man satisfied in bed with those mosquito bites you can barely call tits?"

Michelle's formerly confident smug had faded away and turned into a disbelieving frown after listening to her friend berating Anna, her friend and Kate's even better friend and roommate.

"I'm only bringing balance to the cosmos", Kate said, "people in relationships should complement each other like yin and yang, like me and Mike. In Anna's case, there's a lot of yang but not even nearly enough yin."

"Sure, they could get married, have beautiful kids and grow old together, but would it be happily ever after? Eventually, even if it's on his deathbed, Mike would realize that Anna's lacking, and that he had wasted his years with her. Then he would look back to his college years and remember me, the girl that he let go instead of ditching his bore of a girlfriend in favor of a far superior woman."

"If you're so sure about your theory, why don't you explain this to Mike?" Michelle asked.

"If I want to catch him, I can't tell him myself. His love for Anna is clouding his judgement, and any points to the contrary would just be rejected, like we saw happen last night. No, he needs to figure it out by himself" Kate explained.

"So what's the plan?" Michelle inquired.

"The plan is to not arouse suspicion. We must work behind their backs, drive a wedge between them so I can slip in, and so he can slip something in me", Kate smiled knowingly.

"Excuse me, but 'we'?" Michelle said.

"Of course it's 'we'! I need my best friend's help on this. Last night you proved to be a valuable ally", Kate replied, "and deep down you know that I'm right. You wouldn't have gone after Mike if you knew that Anna was the right one for him."

Michelle stared at the horizon for the moment contemplating her friend's words. She then met Kate's gaze. Kate raised her eyebrow as asking a question, and Michelle knew the answer.

"Fine, I'll help you", she said, "what's our next move?"

Kate smiled.

"I'll start working on putting myself on display. I need to show Mike that I can replace Anna in anything and do it twice as well."

She casually tossed another empty can into the garbage bag.

"And I know just where to start."

*************

The school library was a grand, old building, predating all the other buildings on the campus. Many an architect had left their fingerprints on it; hall after hall and corridor after corridor of distinct, yet subtly different historical feels. Knowledge transferred from scholar to scholar since time immemorial to be finally printed out and stored in an endless sea of bookshelves. Students and library staff roamed the narrow passages between the shelves like ants, occasionally picking up a dusty tome and scurrying off.

A complete void of any kind of sound could have come across as an intimidating experience for most millennials, but there was a certain group of students who were attracted to nothing but. Behind countless hallways there was a large room where one could only hear occasional chatter and small, gentle sounds of plastic pieces placed on wooden boards. That room belonged to the Chess Club.

Kate entered the room in Anna's wake. She looked around; the room was quite large, and vast Victorian windows allowed the whole room to bathe in the afternoon sun. The room was cluttered with small wooden tables surrounded by worn chairs. Every table had a chess board with two sets of pieces, and most of the tables were occupied by students. None of the people, whether male of female, even turned their gazes away from the boards as a girl as beautiful as Kate walked in.

Kate had been anticipating that, although she had dressed up to the occasion of meeting Mike again. She had put on her favorite pink blouse that morning. One that covered a lot of skin but was tight enough to leave nothing to the imagination. Her jeans matched her appearance; her clothes hugging her every curve, highlighting the roundness of her ass and breasts. She thought a tank top and shorts would've been too obvious and scared her prey away. Anna had put on a light sweater as per usual, hiding everything she had. Kate would have never done that; she came to the club to play. She came there to win.

"Hi, sweetie!" Mike came over to Anna, planting a soft kiss on her cheek.

Kate hid her frown. After Anna had greeted her boyfriend Mike turned to Kate.

"Nice to see you too, Kate. Came to escort Anna?"

"Actually", Kate said, "I came here to check this club out."

"Wow. I never thought of you as a chess enthusiast", Mike said, surprised.

"Looks can be deceiving", Kate answered with a smile.

"I convinced her to come", Anna said, "I think she might enjoy this."

"Well, we'll see how she'll do. Have you played before?" Mike asked Kate.

"Very rarely, it has been a long time since I last played. I might not remember all the rules", Kate answered.

"Well, I think as the captain it is my duty to refresh your memory. Anna, you are already an experienced player. You can go ahead and find yourself a partner, I will go through the basics with Kate", Mike said.

Before separating the couple shared another quick kiss, but not quick enough for Kate's liking. Anna hurried of to find a game, leaving Mike with Kate. Mike pulled up a chair on a nearby table and gestured Kate to join him. He quickly placed all the pieces on their respective squares. He set out the pieces so he had the white set and she had the black.

"Do you remember how all the pieces move?" he asked her.

Kate nodded, confirming that they didn't have to start from the very beginning. After making sure everything was ready he said:

"I have the white set, therefore I'll start. You're an inexperienced player, so I'll go easy on you. I'll start with an opening that's quite common in this room."

With that said he picked up his white pawn and moved it two squares. Kate followed his hand, not detecting even the slightest amount of hesitation as he put his plan in motion.

"This is called the Ruy Lopez or the Spanish Game. Your best play would be to mirror my play with your pawn. "

Kate had no objections and moved her black pawn to meet Mike's white one. Mike then picked up his knight and placed it adjacent to his pawn, putting pressure on Kate's.

"Now my knight is threatening your pawn. What's your move?"

Kate thought about her next move. She moved her own knight adjacent to her pawn, protecting it from a possible capture.

"Good move", Mike complimented her.

"Thanks", Kate replied with a smile.

He smiled back, happy that she was clearly enjoying herself.

The game went on for quite a while, Mike giving her advice and correcting her plays. Kate was getting the hang of it; she captured a few of Mike's pieces, but it seemed that for every piece she captured she lost two of her own.

"Ha!" she exclaimed, happily striking Mike's rook out of the board with her bishop, "Gotcha!"

This development wasn't enough to break Mike's confidence.

"Just as I planned: check", he said, picking up his queen and capturing the bishop, putting Kate's king between a rock and a hard place, "just as I had planned. You fell into my trap again."

Kate let out a sigh signaling defeat, but also enjoyment, which made Mike chuckle.

"Wanna go again?" he asked.

"Sure", Kate said without hesitation, picking up her pieces from his side.

"You're quite good for a first-timer", he said, putting his side of the board in order.

"Thanks, I do my best", she replied.

"If you keep up the practice, you'll surpass Anna in no time", he said.

While he studied the board with his eyes Kate's eyes never left his handsome face. His eyes were lit with determination and enthusiasm. His pupils moved, sweeping the board with his gaze. His brain was going mile a minute to figure out a tactic fit for a professional but merciful enough to show a newbie the ropes. Not a single brain cell in his head was dedicated to registering the alluring woman sitting in front of him. Kate felt attraction towards his dedication. She decided to put on the pressure.

As Mike thought about his opening move Kate leaned slightly forward, crossing her arms against the table. She leaned forward as if she was thinking about her first move too, but all she really wanted to do was to rest her breasts against her arms.

As she leaned forward, her breasts began pushing against her arms, ballooning outward, their perfect roundness reaching out for him. She put on her poker face and kept her gaze on the game, but from the corner of her eye she could see Mike's eyes resting on her tits for a split second. She had to fight back not to smile in self-indulgence.

Mike had faced many a hustler in his time, but this was completely new for him. His composure took a slight setback as he registered movement from his peripheral vision. Kate had leaned forward to get a better view of the board, which had caused her impressive chest to swell against her arms. The next thing he did lasted for less than a second, but for him it felt like an eternity. He looked at her tits.

For Mike, who had hooked up Anna, a girl with a chestal area reminiscent of the Bolivian salt flats, this sight was irresistible. Kate's DDs lied there before him like two soft melons waiting for someone to pick them up. Their soft flesh filling the cups of her bra, their creamy skin covered by her torturous blouse. Like a melon had to be smashed open to be feasted on, so had to her blouse. The fabric looked quite thin and delicate; it would easily give in to a man ripping it apart, freeing the delicious pair underneath. If Anna had suckers like those, Mike would never let her out of the bed...

Mike's thoughts rushed back to him. He quickly checked if Kate had noticed. He instantly returned his eyes to the board. She was still studying the game. Good.

He would've died of shame if she had noticed. Her roommate's boyfriend checking out her tits? And if she had heard what was going in his head, how he had imagined tearing her blouse apart. She would've been mad, outraged at his perverse thoughts. Stood up, slapped him in the face and left. True, she had given him her number a few days ago, but since that night at Michelle's she had been cool with it. She respected his and Anna's relationship.

And how would that relationship have changed if she had noticed? She would've told Anna, no doubt. Anna, who was already self-conscious about her appearance, would've burst into tears after her boyfriend was found ogling her friend's breasts. Even if she wasn't going to leave him, it would still have left a permanent scar on their relationship.

He quickly conjured up a tactic on the fly and made his move, hurrying to get past that awkward moment. Unbeknownst to him, she had seen everything and read his face like a book. For the split second he had laid eyes on her, she saw what went through his mind. A flash of temptation. A flash of lust. If he had known how willing she was, she could have practically ripped the blouse open for him herself. The thought made her nipples harden.

"Not yet, girls", she thought to herself, "I'll unleash you upon him soon enough."

It was her turn. Mike sifted on his chair uncomfortably, keeping his gaze strictly on the game. She thought he had made an unoptimal move and decided to take advantage. She made her move. She wanted to be on the offensive this time.

Mike realized the recklessness of his move and chuckled nervously.

"Good, you took advantage of my mistake."

"I'm a fast learner", she replied with a hint of seductive tone in her voice.

He moved another pawn into a defensive position.

"It'll take more than that to beat an old hand like me."

"Yeah, it's probably not the first time you have been cornered by a black."

Her remark made him lost his train of thought. He detached his eyes from the board and looked up, meeting her eyes. She felt like a kitten playing with a mouse as his eyes filled with suspicious confusion.

"What do you mean by that?" he asked.

She tilted her head to the side slightly and raised her eyebrows.

"Michelle", she simply stated.

"I... we... it was...", his words were failing him.

"Don't worry", Kate said with a slight giggle, "it was nothing serious. Michelle would try to sleep with a shaved bear if you put pants on it and got her drunk."

"S-so y-you don't think it was anything serious?" Mike managed to stutter out.

"Not at all", she replied, "she really feels bad for it. Wine just brings out her aggressive side."

"You don't say."

"Besides", she continued, "I know you're a good guy. You would never cheat on Anna."

"S-so you're not telling her?" Mike asked with concern.

"Of course not", she smiled.

She leaned forward a bit more and whispered, putting emphasis on the last word:

"It can be our little secret."

Mike nodded, his mind trying to comprehend the meaning of that phrase. He felt bad of hiding things from Anna, but if Michelle really meant nothing by her actions, maybe it was better not to intervene in their friendship. Anna would've had words with Michelle if she'd been told, which would have ruined a good relationship. He felt like he could trust Kate on this. She seemed like a girl with a good head on her shoulders.

Kate leaned back, uncrossed her arms and pulled back her chest. Mike straightened his back once more and now, quilt-free, could concentrate on the game again.

The game went better for Kate this time, but against a seasoned veteran, she soon found herself defeated again. They played one more game, Kate being white this time. Mike felt a little bit bad beating her twice and thought about losing to her on purpose but thought that he owned her a fair match. Another game followed that one, and then another, and another. Kate decided tune down the flirt, and instead of talking about what happened at Michelle's, they started talking about things they had in common.

It turned out they both had received a similar upbringing. An intact suburban family, one child, strict but fair attitude to bringing up one's offspring. They both had started studying a major they wanted, had enrolled without much effort and that they both took their studies seriously.

They both enjoyed long walks and listening to the sound of rain hitting a window. They both liked the odd wild college parties but also appreciated a quiet domestic evening with a glass of red wine and a good book. They both liked similar music; she listened to Ben Howard and he was a The Lumineers fan. As the turns went on the two people got more acquainted with each other. All this just confirmed Kate's theory; that they were made for each other.
Unfortunately, Mike had not had that realization.

The games went on for quite a while. They only ended when Mike felt a hand landing on his shoulder. He turned his head and saw Anna, who quickly pecked a kiss on his check.

"Hi", Mike said happily.

"It's been two and a half hours now, I think we should take off", Anna said.

She looked at Kate and said:

"Mike's coming over after this, we're planning on watching a movie. I hope that's okay."

"Of course it is", Kate said, "can't stop the two lovebirds from building up their nest."

As much as Kate hated seeing the two of them together, the development had presented an opportunity for a home-court advantage.

Mike gathered the pieces and placed them in a neat order next to the board. He looked around and saw that while he had been occupied by a game with Kate the whole room had been emptied of people. They were the last ones there. He couldn't place his finger on why, but somehow he felt that this time he had been more absorbed into a game than ever before.

*************

"I'm gonna prepare the popcorn. Could you meanwhile put the movie on?" Anna asked Mike after the three of then arrived at the dorm.

"Sure", said Mike like the sweet boyfriend that he was.

Kate made a B line straight to her room without a word. She had to come up with a plan. Fast.

It was already dark outside when they had arrived. They hadn't told her, but it was pretty clear that Mike was spending the night in Anna's room.

She threw open the doors of her wardrobe. She scanned the contents and made a decision. She took off her blouse, then her jeans. She grabbed her loose pajama shirt and pants she used to sleep in.

"Perfect", she thought.

The sleepwear were comfortable to sleep in. Loose and soft enough to warrant a good night's rest. This time, though, the clothes were going to be used in a less innocent plan. Although the clothes didn't hug her curves like her previous set, the wide neck and thinness promoted her assets in a more visual way. And with a hint of perfume, the deal would be sealed.

A good amount of cleavage was clearly on display. The plain white shirt barely covered her bra, leaving a juicy canyon a man could fall into and die happy. She gave her breasts a gentle shake, making the smooth, creamy flesh jiggle. Her black bra was clearly visible under the shirt. As if anyone in the next room was going to complain, she thought to herself. Just a little pull of her shirt and the bra would be visible anyway.

She then proceeded to check that her ass was ready. Her pants covered most of her legs, unfortunately, but they beat any pair of jeans in comfort and thinness hands down. Her ass looked bubbly and perky as ever, ready to mesmerize a man with a sexy swing. Like her bra, her panties were also visible beneath her sleepwear. A black, thin piece a fabric covering her mound and some of her ass cheeks. A piece of fabric that she would be happy to remove should Mike so ask - no - demand.

The sleepwear gave her the perfect excuse to showcase her massive tits and her bubbly ass. Kate closed her eyes and thought about how Mike would react. Would he be the good boyfriend and ignore her body, or would he stand up, walk over to her, push her against the wall and with a fiery change of saliva rip off her clothes, before throwing her onto her bed filling her with his dick like a crazed beast?

She went through multiple scenarios in her head. She could fake losing balance and fall ass-first onto Mike's crotch. Her meaty, soft ass cheeks lodging his ever-growing bulge between them. He would feel her ass grind into his cock as she made an attempt at standing up, a futile effort to be sure.

She could accidentally bump into him holding a glass of water, sending its contents flying onto her shirt. The water would then create a nice, glue-like effect, which would give him an excuse to rub the water off with a towel - or his tongue.

Or... she could just waste no time and stick her tongue down his throat before he would have had time to even look at her. Sit on his lap, push her back against him, grind her ass against his cock and move his hands to cup her tits.

Kate was feeling hornier than she had been in a long time. Her nipples felt like diamonds, demanding to be twisted and sucked. Her pussy flowing with her juices, ready to provide a warm, lubricated hole for him to pour his cum into. She needed him, bad. She needed his mouth on her tits, his hands on her ass, his cock in her pussy. The pleasure couldn't be described with words. They both would give each other orgasms after orgasms, in a tangle of limbs, sweat and pure pleasure.

Kate opened her eyes. While lost in her fantasies, she had slipped her hand down her pants, rubbing her clit. A flood of her juices was forming a wet patch on her pants. She retreated her hand and grabbed a hair dryer, quickly destroying any evidence of what had just happened. She made one final check that her outfit was ready, but firmly assured herself that none of the fantasies was coming true tonight.

She didn't want to push her luck.

She opened the door and stepped out.

Mike was sitting on the couch with a remote in hand, fixed on the TV. Anna was standing next to the kitchen counter, following the circular dance of the popcorn bag in the microwave oven with her eyes. Neither of them paid any attention to Kate, until she stepped forward with a loud stomp. Anna and Mike looked at Kate at the same time, with very different reactions.

Anna kept staring at her with an uneasy expression on her face. She raised a single eyebrow as if to ask Kate why she had emerged out of her room in such an indecent outfit. She knew Kate could sometimes be a bit lose with her choice of clothing, but jeesh. Kate's breasts were not shy about their presence, which made her suspicious. If she didn't know better, she would have thought that Kate was there to make sure everyone in the room knew she was the alpha female. And while her boyfriend was sitting a few meters away?

Mike, however, was not on the same wavelength.

The stomp had caught his attention and he turned to face the source of that sound. What greeted her was the smile of an angel, almost literally. Dressed in white, long blonde hair cascading along her back, red lips curved in a sweet loving smile and her bright, brown eyes locked into his, he could've sworn he had arrived at the Pearly Gates without noticing.

Getting past the beauty of this angel, his eyes wandered her body. Her eyes, her cute, little nose, her red, pillowy lips, her swan-like neck and... her enormous cleavage.

Mike debated himself if her tits were larger than they had appeared to be at the library. Her boobs hugged the fabric of her shirt, pushed together by her bra, practically begging to be set free. Her cavernous cleavage was like a black hole, capturing his gaze and never letting go. He could see the size of them for the first time, as her bra cupped her tits in a way he could only be jealous of, letting some of that milky flesh pouring out of them.

"I assume you two want to be alone, so I'll be in my room listening to music", Kate said nonchalantly, turning sideways to Mike.

She knew what effect that had on him. Mike's gaze continued wandering south. The visible fabric of her bra, her flat belly, her sexy, wide hips and, finally, her ass.

Her perky, bubbly ass. Otherwise so thin and slender lower body made her hips and ass stand out like sore thumbs. Mike could not let that image go. Going downwards her sexy midriff quickly widened into firm, meaty hips. Hips that, as she purposely shifter her weight from one foot to the other, swaying from side to side, made his balls tingle. Like a beckoning finger they lured him closer, injecting life now to his clearly semi-erect dick. They were calling for him, begging him to press his cock against her ass, begging him to take off his pants, then hers, and bending her over. It was a natural instinct, an instinct to enter her and pound her till sunrise. Her girlfriend's roommate. Her girlfriend's sexy roommate. He wanted to fuck her girlfriend's sexy roommate.

Her girlfriend's voice snapped him out of his trance:

"Thanks, come tell us if the movie's too loud."

Anna, still not sure why Kate had dressed as she had, turned back to the microwave. The popping had stopped.

"It's ready!"

Anna took the bag out of the microwave and ripped it open.

"Better get a bowl for these", she said.

Kate watched Anna placing the open popcorn bag on the counter and squatted to reach the cabinet under the counter. Anna opened the cabinet door and started looking for a bowl.

"We should really clean this mess", she said, unable to find a popcorn bowl.

"If memory serves, it was your job two weeks ago", Kate replied with annoyance.

"Could you turn off the lights, sweetie? I'll be there in a second", Anna said, still facing the cabinet.

"Sure", Mike replied from the couch, detaching his eyes from Kate's ass.

The light switch was located right next to the couch, so all Mike had to do was turn around and stretch his arm to reach it. Before Mike could do any of that, however, an idea sprung into Kate's mind. An idea that could risk everything she had been working towards. An idea so dangerous it could bring down the whole house of cards she had built. It could either cement her position as a woman of Mike's desire, or push him away forever. If Mike really felt nothing for her at this point and she went for it, all would be lost. If he felt something for her, however, she could get a permanent headlock on Anna. Should she go for it? Should she execute this idea, conceived of impulsive horniness? Was it worth risking it all?

She wanted to push her luck.

"I got it."

Before Mike could react to Anna's request, Kate had leaped forward. She stopped in front of him and reached for the light switch, turning the light off. A perfectly innocent deed. What happened as a side effect was completely something else. As she reached for the switch, she had to bend over Mike. Bending over him, something happened.

Her tits. Right. In. His. Face.

She could feel her pussy moisten once more as her tits pressed against his face. For a short moment that was needed to press the switch she made sure that he could feel every square millimeter of her delicious rack.

Mike had absolutely no time to react. Before he could even turn around two soft, giant tits smashed against his face. In a mix of panic and euphoria he tried backing against the couch, but her tits were relentless. The DD breasts rubbing against his cheeks, his head sank deeper and deeper into the cleavage. He opened his mouth to object, only to drag his lips against the soft skin of her inner breasts. He tried inhaling through his nose, only to get it filled by the mixture of her aphrodisiac-like perfume and lust-infused natural scent. One half of his brain yelled at him to push this vixen off him, the other half yelled at him to grab her by the waist and coat her areolas with his saliva.

The smooth skin of her breasts felt like velvet on his face. The breasts' every movement, no matter how tiny, was not left unregistered by him. The jiggling of the flesh, how the two globes molded like pillows on his face, creating a cocoon for his head. He had never felt tits like these. Tits that made him rock-hard. Tits that made him drool from the side of his mouth. Tits that felt right.

If Mike was feeling like he was in heaven, Kate wasn't far off. She could feel his breath between her boobs, his lips tasting the milky skin of her chest. Her pussy was now flooding, and her nipples were harder than ever. She quickly glanced at Anna. Anna was still elbow-deep in the cabinet, oblivious to the fact that her roommate was rubbing her tits against her boyfriend's face. Her mind completely clouded by pure lust; Kate wasn't able to think straight. Anna was none the wiser. If she acted fast, she might be able to take off her bra and smother him with her tits, give him complete access to her assets, force her nipple into his eager mouth...

Kate pulled back. She straightened her body, withdrawing her jugs from his face. All rational thought and reason had left Mike's head, and he blankly stared at Kate's bosom like an aquarium fish. As his moral compass started spinning again he looked at Kate with fear and confusion in his eyes. Kate put on a fake, apologetic face and said:

"Oops, sorry."

She tried to keep an embarrassed, apologetic face as she studied his reaction, but that reaction was to determine if she had worked for nothing. If he now stood up and told her to fuck off for literally sexually assaulting him, she would have lost all hope. If he alerted Anna, she would probably kick her out. If he said anything disapproving at all, all could be lost. She waited, staring into his eyes. Was that a glint of anger? Displeasure? Rejection?

They both stayed silent for what felt like an eternity to her.

"It's fine."

He then stood up, walked over to Anna and crouched beside her.

"Let me give you a hand."

Kate stood there, not able to comprehend what she had just done, and even less able to comprehend how he had reacted. No sign of rejection. No anger. Not even a disapproving facial expression. He had not noted her sexual advances in any negative way.

Kate felt like the queen of the hill. Mike hadn't even lifted a finger to stop her from standing up. He hadn't actively tried to devour her cleavage with his lips or even reach up and give her mammoth breasts a squeeze. No sign of consent or returning the favor. But most importantly, no efforts were made to stop her, to put up a fight.

She felt like she was glowing. The man of her dreams had just run straight to the second base, and it felt wonderful. Her nipples were aching for pleasure and her pussy was craving for his cock, but in her books this was a major, major victory.

She sauntered confidently towards the door of her room, leaving Anna and Mike by the cabinet. As she closed her door she could hear a bowl being retracted from the depths of the cabinet, followed by Anna's chirpy voice:

"Thanks, honey, I love you!"

"I love you 3000."

*************

Thump.

Kate woke up. It was pitch black in her room. The playlist on her phone had run out of songs to play, and she put her earphones on her nightstand. The dorm was completely silent. She checked the time on her phone: 1:37 AM. She had fallen asleep listening to music. Based on the silence, the movie had ended in the common room.

She stood up and walked to the door. She pushed her ear against it; no sign of life on the other side of the door. Everything was quiet. She was just about to turn the handle to go take a shower when...

Thump.

This time she heard it. A thumping sound came from behind the other wall, next to her bed. She sneaked over to her bed and pressed her ear against the wall. She new that what was on the other side of that wall was Anna's room.

She could hear whispers from the other side. She held her breath and pressed her ear harder against the dividing wall.

"Are you sure she's asleep?" she heard Mike's voice.

"I just checked on her, she fast asleep", Anna said.

She heard sheets rustling and then Mike's voice:

"Come here."

Anna's giggle could be heard through the wall. For Kate this was torture of the highest order.

More giggling and rustle ensued. Then it became silent for a moment.

"Did you remember protection?" she heard Anna ask.

"Oh, right", Mike said.

Again, rustling of sheets as she pictured Mike getting a condom and putting it on his shaft. The thought of it sent shivers down her spine.

After a moment she could hear Anna's bed thump against the dividing wall as Mike probably jumped on it.

"A-aaahhhh..." she could hear Anna moan quietly.

They were having sex.

She couldn't move away from the wall like she was glued to it. Picturing Mike on top of Anna, slowly entering her, pushing his cock into her pussy... The whole idea was enough to freeze on so many levels. Firstly, the horrible thought of Mike actually fucking her roommate and secondly - the thought of Mike fucking her instead.

"Ahhh... AaaaAAaahhh..." she could now hear Mike's manly voice crack in pleasure.

It was like an electric spark was sent through her body. Jolts of arousing electricity caused every single hair on her skin and muscle on her body tense as she heard Mike moan on the other side of the wall. Shen couldn't help but to slowly push her hand under the soft fabric of her panties. She couldn't help but slid two fingers between the luscious lips of her pussy. She was already getting wet, and even the proximity of her fingers could cause her clitoris to tingle.

"Ohhh, Mike... A-aahh-aaahh..." Anna moaned a bit louder.

Kate could now hear the bed thumping against the wall without pressing her ear against it. The thumping was soon accompanied by the moans of the couple, completely oblivious to the fact that Kate was fingering herself not a meter away.

"AAAaaaahh..." Mike's voice was like a drug to her.

The thumping gained speed, getting more frequent. Mike had to be completely inside her now and getting closer to full speed. Kate's fingers were moving on their own, pleasuring her as she listened to his moaning.

The picture in her head was clear as crystal. Mike on top of her, penetrating her, as she wrapped her legs around his waist and pulled him deeper into her pussy. She pinched her nipple as she thought about how Mike would lower his head and suckle on it.

They would fuck like it was the last day of their lives. Mike pumping into her like a piston, her pussy tightening around his shaft, milking him dry like her life depended on his cum. Her tits would smash against his pecs, her lips against his lips, her tongue against his tongue. His hands roaming her body and squeezing her tits, the tits that now were his to ravage as he pleased.

"Aaaahhh..." a slight moan escaped Kate's lips.

She would be the woman to pleasure Mike every night. The woman Mike comes home to, to watch romantic movies with, to then carry her to their shared bed and pumping her full of his cum. And most importantly, condom would be a forbidden word in that home. A guy like Mike had to be felt bareback. He had to feel her as God intended: no man-made rubber between them. They would fuck like animals every day, and at the end of the day he would pour his cum inside her, as her pussy spasmed from the force of her orgasm, squeezing out every single drop of his seed.

She would suck his cock without hesitation. And that incident that happened earlier? Getting boobs on his face wouldn't be a rare occurrence; a daily dose of cleavage-spelunking would be guaranteed in their relationship.

Kate was closing off her own orgasm.

"AaaAAaahhHHhhh..." she moaned out loud in tandem with Mike.

"Cum in me Mike", she moaned, "make me your woman!"

Her fingers slipped against her clit as a jolt of pleasure struck through her like a lightning bolt.

"AAAAAAHHHH", she moaned, unable to cover her orgasmic pleasure.

She collapsed on her bed, panting heavily.

"Mike..." she thought longingly.

*************

On the other side of the wall, the couple was too engaged in an act of love to notice Kate's self-pleasure. Mike was now pounding Anna fast, in, out, in, out. She was in heaven; Mike's cock stretched her pussy, molding her cunt into a perfect sheath for his shaft. She threw her arms around Mike and pulled him into an intense kiss. Mike answered to her kiss with enthusiasm, never lowering his speed. Anna parted her lips slightly to let out a prolonged moan. The pleasure she was receiving from Mike's massive cock was beyond comparison; her orgasm was closing in.
"A-a-ahhhh... Mike... Harder..." she moaned.

Mike was one never to back down from challenge and upped his speed. Like a cruise liner engine, he kept pistoning in and out of her cunt, making her scream in pleasure. He straightened his body over her and placed his hand on her breast. It was a perky B cup, and squeezing it made her gasp out of sheer pleasure. He liked playing with her tits, and she enjoyed it too most of the time.

Lately, however, he hadn't felt as enthusiastic about sex with Anna as before. When they started going out they would have occasional sex in his bed, standard missionary style. Her ass and tits were always enough to arose him and get him going. But after a while it stopped being as easy. Maybe the honeymoon phase of their relationship was over, he reasoned to himself. He would turn her over to spoon her, her flat ass against his crotch, to get some variety. But even that was running out of novelty.

"I-I'm coming... I'm coming!" Anna yelled, feeling her orgasm approaching her.

Mike closed his eyes. A mental image flashed before them. A swaying ass, inviting him to a natural breeding process. A set of tits out of nowhere, pressing against his face, pulling his head into a deep embrace. The red lips, curved into a smile, blowing a kiss at him.

He opened his eyes. Anna kept moaning, unable to talk properly. He looked at his girlfriend squirm in pleasure. A mental picture took over, and the twisting form of her angelic, sweet girlfriend began to warp before his eyes. Her face started to reshape. Her hair started to grow and turn gold. Her hips began to widen and belly flatten. Her B cups started to swell, growing into two familiar shapes.

Her blond hair ran over her shoulders, hugging the sides of her huge breasts. Her freckle-free face smiled at him with red lips. He looked straight into his girlfriend's now-brown eyes.

"Fuck me, Mike", Kate whispered.

There was no force in the world to stop Mike from fucking her like there was no tomorrow. His massive dick made Kate scream in pleasure, her DDs bouncing up and down as he pounded into her. He dived down and met Kate in a fiery kiss, invading her mouth with his tongue. The alluring scent of her cleavage returned to his nostrils, driving him wild.

"I love you", Mike managed to whisper between intense make-outs.

Anna felt Mike's dick grow even larger, reaching a size she had never experienced before. He was already stretching her pussy to its limits, just a bit more and she would probably rip in half. Mike's unprecedented enthusiasm and sudden confession of love were more than enough to send her over the edge. The spasm of her cunt and Mike's own fantasies were unbearable to him; he erupted with force, filling the condom with hot cum.

"AAAAAHHHHH" both screamed in unison.

Anna's body squirmed in pleasure, not being able to calm down after an orgasm that intense. Mike's body shuddered as jet after jet of his own seed poured into the rubbery pocket. He had never experienced an orgasm of that magnitude. He could not think straight. He could not think of Anna, her loving girlfriend, or anything else in the world for that matter. There was only one thing, one single thing in the world that mattered. As he tried to calm his pulse and push the last drops of cum out of his dick, a single word echoed in his head. He did not know whether it was him or his subconscious, but he could not stop moaning that word in his mind. The word that meant everything to him, the word that defined the best sex he had ever had.

"Kate..."
