“Happy Birthday!” Alice shouted with a wide smile on her face as soon as Lisa opened the door.

Alice was taken aback at the sight of one of her closest friends. Lisa’s blonde hair was parted in the middle into a double ponytail. The tails were curly and lying casually on her naked shoulders. It must have taken a lot of time and effort. The petite blonde wore a shoulder-free tight top, and by the shape of it, and her nipples clearly forming underneath, it was obvious that Lisa wasn’t wearing a bra. The 'top' basically just covered her breasts like a big white tape, which ended shortly after. Alice had no idea that Lisa even had that much of a rack; she must have hidden them very well in the past. Her belly was free, and the white leather skirt matched the rest of the outfit, although it was very, very short. Lisa seemed taller, too, and Alice realized that she had never seen Lisa in high heels. They were white, of course, just like the rest of her outfit.

“Alice, finally!” Lisa exclaimed and gave her a tight hug. Lisa was so short that she almost buried her face in Alice's breasts if Alice hadn't bent down fast enough. “You look hot! Really gorgeous dress!” Lisa said once she let go of her.

Alice just bought it last week on a shopping spree with Melissa. It was actually Melissa's idea to wear it tonight. It was red and made of silk, with such a low cut in front that her breasts were only covered from the sides and nicely shaped in the middle. A few weeks ago, she would have felt embarrassed and exposed walking around like this, but now she felt pretty sexy. Especially with Melissa praising her looks all the time.

“Thank you very much, but I think you look so much hotter! I can barely recognize you!”

Lisa waved it off. “Oh, this? It’s nothing,” she winked at Alice. “So, who did you bring me here?”

Alice gulped and stepped aside. “This is Melissa. I hope you don’t mind me bringing her?” Alice had feared this moment. Lisa could get jealous of her female friends when it came to Alice. Usually, that made Alice feel special, but sometimes it could be a problem. Especially since she had neglected Lisa more and more lately, to spend time with Mike, Jake, or Melissa.

“So this is my latest rival?” Lisa said with a giggle and hugged Melissa.

“Happy Birthday!" Melissa said and returned the hug. "It’s so nice to finally meet you!”

This time, it was Alice who felt slightly jealous. She would love to hug Melissa again. Especially when she looked this gorgeous. Compared to Lisa and Alice, Melissa almost looked prudish in her olive green dress. It didn’t even show that much cleavage, but Melissa’s breasts were so big that she didn’t need any cleavage to make an enticing appearance. With her golden creoles and necklace, she looked equally exotic and elegant to Alice. Lisa slowly ended the hug, her eyes resting on Melissa's breasts for a fleeting moment. “We’re gonna have so much fun!”

This was the first time that Alice thought something was off about Lisa, aside from the daring outfit. Was she already drunk?

“Welcome to the party!” Lisa announced as she let them in and closed the door behind them. "Let's head to the kitchen first and get you something to drink."

Lisa led them into the kitchen, where Amy and Jacob seemed to have one of their usual spats. „I just don’t want her to dry hump you again, like last time.“ Amy rolled her eyes.

„Oh, come on, you’re exaggerating," Jacob replied, sounding exasperated. "She was so drunk she could barely walk.“

„Well, she can find someone else to look after her tonight, then, is all I’m saying, and if- Oh, shit, hey Alice, long time no see! How are you?!“

„Hi Amy! All good, you know?" Alice put on a smile. "How about you guys?“

Amy waved her hand. „Nothing you don’t already know. Still engaged and all. But what about you? I heard you dumped Jake and got yourself a doctor? Where is he?“

Alice licked her lips. „Uhm, well, he had to work, but I brought his sister. This is Melissa.“

Melissa shook hands with them, and they made a bit of small talk. Amy and Jacob left to continue their discussion somewhere else.

There was a small collection of filled champagne glasses on the table waiting for them. Lisa gave each of them a glass. „Cheers, ladies, I’m so happy you are here!“

Alice and Melissa toasted to Lisa's birthday, and Alice was happy to finally have a normal evening out and just be with friends. Although Melissa was alluring as ever, Alice felt safe in this environment. That was, until Jake entered the room.

„Lisa, your guests are demanding you in the living room. Oh, hey Alice.“

„Oh, alright!" Lisa replied. "Do you have everything you need, Jake?“

Alice's eyeballs popped out as she saw Lisa gently put her arm on Jake's chest. What the fuck?

„I’m fine, thanks,“ he replied with a smile, and turned to Alice and Melissa while Lisa left them.

„What are you doing here?" Alice asked. "I mean... she invited you?“

Jake shook his head, looking mildly confused. „Of course she did. It’s my friend group, too, you know? Anyway, nice to see you, Alice.“

Alice was still dumbfounded that he was here. She had to be careful around him, especially with Melissa standing right next to her. Alice made sure to act as casual as possible when Jake frenched her in greeting. When Jake was done kissing her, she tried to look unfazed, so that Melissa didn’t get the wrong idea.

„Nice to see you too,“ Alice replied and patiently let him squeeze her breasts while checking her out. Nothing out of the ordinary so far, which was a relief. Alice even gave Melissa a look and rolled her eyes, as if she was annoyed. She had to be careful not to make herself suspicious.

„You look hot,“ he concluded, and Alice felt herself blushing.

„Thanks," She replied meekly. "You remember Melissa?“

„Of course, I do." Jake turned to face her. "Nice to see you again.“

„Hey.“ Melissa said, and shook his hand, her expression polite.

Jake grabbed a beer from the fridge. „Gotta find Jacob. Need to talk to him, man to man. If you know what I mean?“ He winked at Alice and left.

Melissa raised an eyebrow. „Any idea what he means?“

„No clue.“

They both chuckled.

„So, you're okay with your ex being here?“

„I don’t know... I mean, I don’t really care about him, but I think Lisa is acting off.“

„She seems to be a bit tipsy, but it's her birthday party, after all.“

„No, that’s not it. I mean, yeah, that too, but she hates Jake. At least she used to... This is strange.“

„I don’t know about that." Melissa leaned in. "Maybe she just didn’t like you two together. Maybe she likes him.“

„What?! No way! Trust me, I know her.“

„Didn't look like hate to me - Quite the opposite, to be honest.“

„I have to talk to her. I think he might have done some... Never mind.“

„What?“

„It’s nothing. I just have a bad feeling about this.“

„Are you jealous? I won’t tell Mike if you are. It’s okay.“

„I... No, I’m not. I swear. Why would I be jealous?“

„Just a hunch. I mean, you did love him once, didn’t you?“

„Yeah, but that doesn’t mean... Why are you so obsessed with this anyway? You know I’m dating your brother, right?“

Alice got weary of Melissa's questioning. It was as if she wanted Alice to admit something. She felt very alert about this, and it was also a bit odd.

„I know,“ Melissa said, and came slightly closer. She whispered, „But I also know that you and I have a dirty little secret. Maybe I’m the jealous one?“

„Don’t do this to me now!" Alice hushed, "Let’s go to the others, alright?“

„Sure!“ Melissa grinned, back to normal, and they walked out of the kitchen.

Alice and Melissa greeted everyone in the living room and sat down on the couch. 

Melissa crossed her legs and turned to Alice. „Okay, give me the 'Who's who'.“

Alice pointed at the living room table. Three quiet, bigger girls were sitting there. "They are in Lisa's feminist club at the university. They can talk your ear off if you're not careful. All in all, super nice girls, though."

"And why are they giving Lisa the stink-eye?"

“I guess because she is a bit too drunk too early? I don’t know, I mean, look at her...”

There was a handful of people on the dancefloor, and Lisa was right in the middle, dancing with a slim guy with horn-rimmed glasses and bad acne. It looked like she was twerking on his dick.

"Greg has had a crush on her since forever, and everyone knows it." Alice explained, "You need to understand that Lisa is usually very conservative, quiet, and... basically the opposite of what you're seeing tonight. She just doesn't get like this, even when she's drunk. That’s what worries me."

Melissa shrugged. "Maybe she just wants to enjoy her birthday? She looks happy."

"Yeah, I guess. Over there in the armchair is Amy, whom you met in the kitchen. She and Jacob have been together since I've known them. They seem to be always in a fight for one reason or another, and I guess today is no different." Amy sat there with crossed arms, pouting at nothing in particular.

"And who is that?" A girl with long dark hair, a big, excited smile, and a lot of cleavage just entered the room. "That's 'one reason or another'. Evie is always flirting with Jacob, and he is the only person on the planet who doesn’t get it. Amy does, obviously." Melissa nodded, noticing the spiteful way Amy looked at Evie, who didn't seem to notice and joined the dancefloor with a loud, "Whooooo!"

Shortly after, Jacob and Jake entered the room, each of them carrying a plate filled with shots. Alice felt her face getting hot, and she tried to avoid looking at Jake. She remembered how he fucked her yesterday when she wore the leather kitty costume. Alice quickly shook her head. This was not the time to think about that.

Jacob started to serve out shots at the table and dancefloor, while Jake came over and put his tray down in front of them.

"Cheers," he said and took one of the little glasses. Alice did a shot with him and was relieved that he joined the others on the dance floor right after. He left the tray of shots in front of them.

"I should not drink too much tonight." Alice told Melissa, "I have a feeling that Lisa is going to need me soon." 

"Look at me."

Alice was struck by the commanding way Melissa spoke and turned to her. As soon as she looked into her hazel eyes, Alice felt her heart skip a beat.

"You should totally have some fun tonight, don't you think? I can't drink because I have to drive, so I can look after Lisa and you. You trust me, don't you?" Melissa just had the sweetest voice. The answer was obvious.

"Of course I trust you." Alice looked down as Melissa pressed another shot glass in Alice's hand, and Alice felt a very special tingling where their fingers touched. Alice looked up again.

"Drink up, Alice. Tonight's gonna be so much fun!"

Alice nodded and gulped it down.

***

Two hours later, the place was crowded. Lisa had never felt this alive and happy. And she got so much attention! Everybody seemed to have a great time, too. Except for her jealous feminist friends, but they left early, thank god. Lisa was dancing with Greg a lot and was totally planning on sucking him off soon. His boner was grinding her for hours, and she loved the confirmation that she looked hot. But then Jake came and grabbed her for a dance. Greg seemed pissed, but Lisa didn't care - Jake was a priority, obviously. He was the hottest guy she knew.

They danced some more, and Lisa noticed soon that Alice was staring daggers at her. She looked drunk, too. Lisa shrugged it off. This was her birthday, after all.

A few minutes later, when Lisa left the bathroom, Jake stood in front of her.

"Sorry, I didn't know someone was waiting." She smiled seductively.

"I'm not here to use the bathroom," Jake said with a smirk, and put his hands on her waist, pulling her close.

Lisa relished making out with her crush. Someone shouted something. Jake stopped kissing Lisa, and they both turned their heads to look at Alice, all red in the face and full of anger.

"I thought you were my friend, but you jus' a bitch traitor!"

Lisa noticed that Alice could barely stand. How much did she have to drink?

"Shit, Alice," Lisa said, worried about her friend. "I think you should sit down. You look like you need some water."

"Bitch!" Alice shouted again, and then Melissa came. The caramel-skinned beauty put her hand on Alice's shoulders and spoke to her, calming her down. Lisa thought that Melissa did a great job, guiding Alice away, back towards the living room. Lisa turned back to Jake. He seemed rather amused.

"What are you so happy about?"

"Oh, so many things, Lisa. This is a great party." Jake chuckled and slid his hand under her skirt to grope her ass. "Get me another beer, will ya?"

He walked back to the living room while Lisa giddily hurried to the fridge.

***

Alice felt dizzy, and everything was blurry. She remembered shouting at Lisa, then talking to Melissa. At some point, she was in Melissa's car, where she kept falling in and out of sleep. Now she was in Melissa's bed and watched her sexy best friend undress.

"You're so hot!" Alice heard herself blurt out in a voice she barely recognized.

Melissa sighed and dropped her dress. "And you are very drunk." She looked at Alice and revealed a confident smile. "Which is exactly what I wanted."

Alice giggled. "Why?" she asked, anticipating Melissa to drop her bra.

Melissa bent over to Alice. "Because I want to do some nasty things to you."

"What are you talking about?" Her tongue felt heavy.

Melissa dropped her bra, and Alice was mesmerized by the sight of Melissa’s gorgeous tits. Melissa easily pushed Alice down on the bed and sat on top of her. She bent over and put a finger on Alice's mouth.

"We're done talking, little slut."
