"Hi!" Michelle greeted Kate and Anna who stood at her doorstep, "Anna, you were able to come!"

"Hi, Michelle, long time no see!" Anna replied with a smile.

Michelle stood at the door, wearing a long, black dress and chain earrings, bringing out her natural complexion. Opposite of her stood Anna, wearing her high-cut green shirt and beige khakis. Next to her stood Kate, who had decided to wear a less-conservative pink blouse with a low cut and leggings.

Kate picked up her plastic pack and stepped inside with Anna right behind her. They walked across Michelle's living room to the kitchen counter, and Kate emptied the bag's contents on the tables. Cans of beer, bottles of wine, spirits, soda, juice, you name it. Kate had come prepared. Anna, on the other hand, had only a few ciders with her. She had told Kate earlier that she had to wake up early to write her essay, so she couldn't stay long.

"Kate told me you're seeing someone," Michelle said with an increasingly questioning tone in her voice.

Anna blushed a little.

"Yes, he will join us soon. He has Chess Club every Saturday afternoon."

"So a chess nerd," Kate said before Michelle even got her mouth open.

"Is he hot?" was the second thing to come across Michelle's mind.

"Apparently so," Kate said, as Anna's face turned even more red.

"Well. Miss Lucky, open that bottle of wine for me. We'd better start drinking, the other guests will be here soon," Michelle said and grabbed a glass.

"You expecting to meet someone, Kate?"

"Seeing how these people will mostly be your friends, not likely," Kate answered.

Michelle frowned at her, causing all three girls to laugh. Anna tossed the opened wine bottle to Michelle, who then proceeded to help herself.

"You never know, you might find Mr. Right One today."

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

Sure enough, more people turned up soon. Michelle's neighbors, classmates, old high school friends, acquaintances and drinking buddies. Michelle shared a glass of wine with anyone who showed up at her door, and greeted them with increasing affections as the night, and the bottle of wine, went on. The night had started out great, with casual chit-chat, background music, and most importantly, alcohol. Anna, not so familiar with Michelle's friends, stuck to Kate, who had struck a conversation with one of her and Michelle's common friends.

"Anyway, when's your man gonna show up?" Kate turned to Anna, who had been sipping on her first cider for a few hours now.

"He just texted me he's climbing up the stairs. Should be here any minute now," she replied.

As Anna finished her sentence, they heard the doorbell ring.

"Must be the man of the hour," Kate said cheerfully, forcing her beer can on Anna.

"I'll get it."

On her way across the room she tapped Michelle on the shoulder, letting her know that a new guest had appeared.

"Awesome, I needed an excuse to have another drink!" Michelle exclaimed with a subtle slur.

"It's Anna's boyfriend, so get a hold of yourself," Kate said and reached for the front door.

"Welcome!" Kate cheerfully said as she opened the door, only to be completely silenced a nanosecond later.

She was greeted by a pair of blue eyes, expressing both confusion and surprise at the same time. The blue eyes that she had stared into a few days earlier. A man stood there, wearing a black t-shirt and jeans, and the same hipster glasses. Kate and Mike stared at each other without a spoken word.

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

"I thought you weren't able to come!" Kate said, still overtaken by a shock of seeing Mike.

"Well, at first we were planning to see a movie, but nothing good was on, so we decided to come here instead" Anna said, leaning to Mike's shoulder and taking a sip of her cider.

"If I'd known you're friends with Anna, I would have said yes," Mike said and opened his beer with a satisfying 'psshh'.

"So how did you guys meet?" asked Michelle.

Anna and Mike looked at each other.

"Well, I wanted to take up chess to relax and forget about my lectures. I looked up the Chess Club online and decided to go have a look. As a new player I ended up playing with the captain, Mike, and as he explained the newbie strategies to me we started talking about other things. After the club he asked me to be his Facebook friend, and we continued our conversation online. Little by little our mutual affection grew and... here we are!" Anna explained, with a smile one both of their faces.

Kate took a long sip of her beer. She couldn't believe that the man she had flirted with and given her number to, was going out with her roommate. The roommate who let her take care of the chores as she ran around town joining chess clubs and hitting on perfect guys. She watched as Mike planted a kiss on Anna's forehead. Maybe it was the alcohol, maybe it was the background music, maybe it was the crowd of people surrounding them, but something caused dark clouds of jealousy to gather within her head.

"She's so sweet! I'm happy that I can call myself her boyfriend now!" Mike said happily, raising his beer can in toast.

Anna kissed him on the cheek and Mike pulled her closer to his body in a hug. Kate was just about done.

"If you'll excuse me, I have to powder my nose."

She started making her way towards the toilet, yanking Michelle by the arm with her. She made sure that she was out of the hearing range and turned to Michelle.

"Isn't it funny that the guy you were hitting on is actually seeing your friend?" Michelle giggled, alcohol making her completely oblivious to Kate's frown.

"Hysterical. I need you to do me a favor."

"What's that?"

"I want you to keep him and Miss Kissy-Kissy apart from each other."

Kate saw Michelle's face turn confused.

"Why?" she asked, taking another sip of her wine.

"Because I need a night to not care, alright?" Kate was growing more and more frustrated.

"You still on about that, sis?" Michelle said and looked across the room where Mike and Anna were engaging in a nose kiss.

"Just do me a solid this once, and I'll introduce you to a member of the college basketball team," Kate said.

Michelle turned back to Kate, not being able to hide her enthusiasm.

"You got yourself a deal, missy!"

Kate took Michelle's hand and lead her back to where Mike and Kate were standing. Kate had to clear her throat in order to gain their attention.

"Anna, would you help me open another bottle of wine? My hands are kinda sweaty," Michelle asked, taking Anna's hand without a heads-up.

"Umm, s-sure," Anna said as Michelle was already pulling her towards the kitchen, leaving Mike and Kate alone.

"So," Kate said, turning to face Mike, "whatcha really think of her?"

"Anna's really sweet, it must be great living with her," Mike answered, taking a sip.

Kate didn't know how to answer that at the moment, so she took a sip of her beer as well.

"This party's great, it's nice to meet you and Michelle again. Like you said, we were bound to run to each other again," Mike said, breaking the silence between them.

"Yeah. Sorry about that by the way, I shouldn't have given you my number."

"It's fine, I threw it away already," Mike said with a nervous laugh.

That made Kate's stomach turn. He had thrown away her number. He really had no interest in her.

"Well, that's good, you and Anna seem cute together," Kate said, hiding her true emotions.

"Thanks, I really think this could become something more," Mike said, directing his gaze towards Anna and Michelle, who were in the process of opening yet another bottle of wine.

As Mike's attention was elsewhere, Kate did something. Maybe out of intoxication, maybe out of desperation. But she did it anyway. She subtly slid her free hand downwards and pulled slightly on her blouse, exposing more cleavage.

"She mentioned you got familiar over a game of chess. How's that?" she said, regaining his attention.

Mike looked at her beautiful face and wondered why her body had become so much enticing to look at. He decided not to think about it too much and instead focus on the question presented.

"Chess? Oh, it's great! The excitement of a battle first started centuries ago, the number of possible games exceeding the amount of atoms in the universe, the fierce strategic struggle of minds as both combatants charge into battle, trying to slay the opponent's king. It is just fantastic!" Mike explained with great enthusiasm, chess clearly being close to his heart.

Listening to Mike go on about chess made Kate happy in a way she couldn't quite explain. Maybe it was her mannish looks combined with his boyish passion for the sport. It could also have something to do with his compassion for mental games. This was a man who appreciated mental stimuli as much as Kate, and maybe even more. This, however, didn't help Kate's growing arousal.

As Mike went on about the subtleties of different strategies, Kate eyed him up. His black t-shirt really highlighted his biceps she had seen earlier, but this time she was also able to notice his broad chest and slightly muscular stomach. His jeans were able to hide the most precious things, but based on the curvature and bulge she was able to see, Mike wasn't far from a 12" pianist.

As she finished her beer, a thought run through her head, and this time it stuck. She had to get him.

"If you'll excuse me, I'll go get another beer," she had to interrupt his cute little rant, "I'll be right back."

She walked over to Anna and Michelle, who had been successful at opening the bottle. However, Michelle was in state in which she, whilst aiming for her glass, poured half of the wine on the kitchen table.

"Give me that, you'll get us both wet and dirty," Anna said and snatched the bottle from Michelle's hands.

"How's it going?" Kate said walking to the opposite side of the table.

"It'shh going finehhh" Michelle was able to slur, the wine clearly gone to her head.

"So it seems," Kate said and looked at Anna, "he seems like a good guy."

"He does, doesn't he?" Anna said, pouring another glass of wine.

"I think he's finished his beer by now. Take one from the fridge and bring it over to him, my treat," Kate said, faking a friendly demeanor.

"Thanks! I'd give you one of mine, but I only have cider," Anna said, took a beer from the fridge and left then kitchen.

Anna made sure that she had left the room before she turned back to Michelle, drinking her wine like a woman dying of thirst.

"I need you to do me another solid."

Michelle raised her index finger to signal she wasn't done with the wine yet. After she had emptied the glass she smashed against the table and slurred:

"What'shh it about nowhhh?"

"I need you to hit on him."

Michelle's mouth sprung open as her drunk eyes widened with confusion.

"Huhhh?"

"I need you to. Hit. On. Him."

Michelle looked around the kitchen trying to find a third party who could help her make sense of things. As nobody came, she then repeated her previous argument:

"Huhhh?"

Growing impatient, Kate pulled Michelle's head closer to reveal her freshly-baked plan:

"I need you to hit on him to see if he can be cracked. I can't do it, because it would be too obvious. You, on the other hand, are drunk like a fish on New Year's, and have the reputation of a girl who will hit on a her own step dad if he's packing, so no losses there. I will distract Anna, and you will throw yourself at Mike. Got it?"

"And what'shhh in ithh for me?"

"I'll get you a basketball player and a rugby player."

Michelle's eyes lit up like a kid's on Christmas morning.

"You got ithh, I'll have my tonguehhh down hishhh throat before you can count to fivehhh!"

Now, for any other girl this would've seen like a big gamble, sending your best friend at a guy you fancied, but not for Kate. Kate had seen what Mike was able to withstand, and how devoted he was to Anna. Kate knew that Michelle was sexy, no doubt. Skinny, beautiful, skin like chocolate, firm C cups and an ass to go with them, and the sexual aggressiveness that her wine had brought to the surface. She was hot, but if Mike had resister Kate a few days before, even drunk he should be able to resist Michelle. Michelle was just the breeze that would come before the storm.

"Hey, Anna," Kate said as she walked Michelle back to the couple, "could you see me over there for a second? I need your help with something."

"Sure," Anna said, slightly confused, but ready to help her friend.

She let go of Mike's hand, passed Michelle, who was giving the weirdest looks to him, and followed Kate back into the kitchen.

"What's up?"

"Well, you see..." Kate started, opening another beer, "I have some guy troubles."

"You? Guy troubles?" anna laughed, "You're not getting enough guys, is that your problem?"

"Har, har, har," Kate said, feigning mockery in her voice, "It's serious."

Anna studied her roommate's face for a second, and said:

"Gosh, you are serious! What's the problem?"

"Well, there's this guy I like, but... it's complicated. We'd better sit down."

Kate pulled up a chair and sat down, drinking her beer. Anna looked over her shoulder towards the living room door.

"Umm, do we have to do this now? I kinda wanted to spend the night with Mike."

"Please, Anna," Kate begged, putting her acting skills to a test, "I need you now more than ever!"

Anna let out a weary sigh and pulled up a chair.

"Start from the beginning."

"Well, it all started three months ago..." Kate started her story, smiling devilishly inside.

Meanwhile, in the living room, Michelle was preparing for the grande finale of her night. She was now alone with Mike in the corner where other people could hardly see. She was a tiger, this man before him was a lion, and there was room for only one king of the jungle.

"So," she managed to say, "You and Anna doing ithh often?"

This made Mike cough up the beer he was drinking.

"Excuse me?"

"Well, Anna'shh not so bad-looking, and you'rehh a guy girlshh would only dream ofhhh. It only makeshhh sense," Michelle raised her wine glass to her lips, winking at Mike.

Mike blushed form jaw to ears. What was this girl he had just met saying? And wasn't she Anna's friend? Maybe it was the wine, it had clearly gotten to her head.

Mike decided to play it cool:

"Our relationship just started, I-I d-don't want to go into the details."

Michelle nodded and shifter her weight, causing her hips to sway slowly.

"I get ithh. I mean, Anna'shh one of those sweet, innocent summer children. She'd make a lovely girlfriend, but I'm not so surehh about her... sexual abilitieshhh."

As the last two words left her lips Michelle slightly pushed her chest forward, putting her juicy cleavage on display. She then locked eyes with him, only to slowly guide his gaze down to her chocolaty tits, where spilt wine had formed a stream down between her globes. Mike had no option but to take it all in.

"I mean, she'shhh not a girl like me," Michelle said, taking a step towards Mike.

Mike gulped and took a step back. His back hit the wall. Michelle pushed her chest further out and took another step, while smiling seductively. Mike's gaze was now burning holes on her dress. Michelle took another step, and was now standing as close to Mike as she could without touching him.

"I know how to handle a white boy," Michelle said with aggressive lust now clearly on display.

Mike couldn't escape this crazed woman. Her proximity made him extremely uncomfortable, not to mention the racial turn her dialogue had taken. He had to think of a way out.

Michelle took advantage of her opponent's agitated state and leaped onto him, pressing her body firmly against his. Their skins only separated by the thin fabric of their clothes, her tits smashed against his chest like a wave crashing against a rock. He could smell her perfume, she could smell his cologne. He probably couldn't smell it, but she was getting wet.

"Put your armshh around my waist," Michelle said in a commanding tone.

Mike's head was spinning. The beer, the music, the dark vixen throwing herself at him, it all made him feel dizzy. His brain was on the verge of a shutdown, and his arms moved by themselves, pulling Michelle closer to his body.

"Ahhh..." Michelle let out a quiet moan, bringing her lips to his ear.

"I like a man who does what he's told," she whispered into his ear.

"P-please, I l-like A-Anna..." Mike was able to stammer.

"You won't be able to remember her facehh once I'm done withhh you..." Michelle said, softly pressing her lips against his ear, sending shivers down his spine.

She then pulled her head back so her face was only centimeters away from his. He could not help staring into her eyes and vice versa. He could smell her perfume and the wine in her breath. Michelle started moving her head slowly forward.

"You'll stay the night here. Or... we could go to the bedroom right now..." she purred closing her eyes.

Mike's brain was in total state of rebellion against his heart. He wasn't proud to admit it, but he was rock hard, and Michelle rubbing her breasts against his chest and seducing him with her words were not helping.

Mike closed his eyes, as he felt Michelle's breath coming closer and closer towards his own lips. Michelle leaned forward, eyes still closed, feeling his pulse getting faster and faster, preparing for her triumph. Her lips ready to meet his. Her tongue ready to dance with his.

Mike's eyes shot wide open.

"What the fuck!" he exclaimed, causing Michelle to take a step back in shock.

"Anna's my girlfriend!" he said, panicked, burying his face in his hands.

He then quickly jumped around Michelle and with a quick pace walked over to the kitchen door, leaving a surprised Michelle standing in the corner to wonder what just had happened. Mike opened the door to the kitchen, where Anna and Kate were sitting. Anna turned around to face her boyfriend, and Kate, seeing the color faded from his shocked face, knew exactly what had happened. She smiled to herself, but Anna, none the wiser, had no idea what had just taken place in the other room.

"Hi, sweetie. Is everything ok?" she asked.

Mike had a quick thought-collecting moment. Should he tell her what he had just done with Michelle? How close they were of kissing? Of making out? While his girlfriend was sitting in the next room?

But Michelle was really drunk. So drunk, that maybe she couldn't suppress her sexual behavior, and took it out on him. Should he break the news to his girlfriend, that her friend was pushing her tits against his chest just a moment ago? In her friend's home, during her friend's party?

Kate immediately saw what was going on in his head, and decided to intervene:

"I'm sorry that I left you alone with drunk Michelle. When drunk she can sometimes be a bit pushy and not always comprehend the world around her."

Mike thought about this statement. If Michelle really was so drunk that she forgot about Anna, maybe this wasn't such a big deal. He'd only had to avoid her in the future when she'd be drunk, and besides, she probably wouldn't remember tonight in that state.

"Y-yeah, i-it's... fine," he managed to say, catching his breath, "but I think it's time for us to leave. It's getting late."
Anna looked at the clock.

"I guess, I have an essay to write. Shame we couldn't stay for longer, though."

Without a word Mike left the kitchen, Anna in his wake. Mike made a B line straight for the front door, but Anna thought it was only polite to say goodbye to the hostess. She noticed Michelle in the corner, leaning her back against the wall. She walked over to her.

"Hey, Michelle, we're thinking about taking off. Thanks for the great party!"

Michelle's eyes like glass, she stared into nothingness, her mind clearly occupied by thoughts and a sailor's dose of wine. She noticed Anna next to her and turned her head.

"Anna, you're leaving? What about Mike?"

"He's taking me home. Sorry we have to leave so early, I got an early morning tomorrow."

"It'shhh fine. Tell Mike I'm happy he came by."

Anna left Michelle's vicinity, and Michelle immediately turned around, bumping the wall with her head. She couldn't fathom what she had just done to Mike, and more to the point, Anna. If Mike wasn't such a devoted and loyal boyfriend, they would've been making out by now, probably even be fucking on her bed; Mike balls deep in Michelle's pussy, Anna drinking cider in the kitchen. Her sluttiness had reached new heights.

She couldn't contemplate her life decisions for long, though. Kate appeared from the kitchen, beer in one hand and a devilish smile on her face. Michelle turned to face her and gave her the most disgusted frown a best friend can give another.

"I hope you're hhhappy. I couldn't facehhh Anna ever again if shhhhe found me riding her boyfriendhh."

"Don't take this the wrong way, but I seriously doubt that was going to happen," Kate said, throwing Michelle's arm over her shoulders and grabbing her waist.

"Then what washhh even the point?" Michelle asked as Kate carried her towards the center of the room and the other guests.

"To see if he could be cracked, you idiot. Of course he wouldn't fuck the first random floozy who threw herself on him, he's way too devoted for that. All I needed to see was the look on his face when he ran into the kitchen. You know why?"

"Why?" Michelle gave her a confused look.

"Because that face told me that he was afraid. Afraid of something that could've happened. Afraid of his own weakness. There was zero chance he was going to end up in bed with you, sorry to break it to you, but he couldn't see that over his panic. Deep down he knows that there is a woman who can break through his defenses, to finish the job, to slay the king," Kate explained with fiery sparks in her eyes.

Kate lowered her voice as they approached the other guests, people who had no idea of the sexual developments of the evening. She let Michelle stand on her own two feet again. As the playlist started playing a new song she whispered:

"This was just to test the ice. He might think he gained a defensive victory, but with a small sacrifice I was able to get the upper hand. Trust me, the war is far from over."
