Aubrey starred at Beca with a look that was a combination of shocked, disgusted, and turned on. "You're not serious are you, Beca?" The blonde asked with an amused laugh that she let herself think for a second that the brunette was seriously suggesting this.

"Actually, yes I am." Beca responded with a stone cold expression.

The blonde sat back and seriously considered what the brunette was suggestion. She had been wracking her brain for weeks about what to get for her girlfriend and best friend for their birthdays on Saturday. Beca's suggestion would take care of both at once and she knew for a fact that they would both like.

Aubrey let out a laugh of frustration, knowing that Beca had her in a checkmate. "You know the only reason I'm even considering this is because you're my best friend's girlfriend so I know you're clean and we're doing it for Stacie and Chloe and we won't catch feelings for each other, right?"

The brunette waved Aubrey off, "Don't worry Brea, I know that you aren't into kinky shit and you find me and my piercings repulsive and it's only simulation, blah blah blah."

The blonde nodded in joking seriousness. "Exactly. But in all seriousness, you don't have the slightest concern that this could backfire and ruin our relationships with Stacie and Chloe, but all of our friendships?"

Beca let out a heavy sigh. "of course it did and still does, but I also trust all of us to understand that it has nothing to do with feelings, it's just a show we're putting on for them."

Aubrey let out a sigh of defeat. She knew that Stacie and Chloe would really love this gift and if she was being honest, the idea of having sex with Beca was something that turned her on more than she'd be willing to admit. "So what are the logistics of this plan," Aubrey asked with more than a little cockiness in her voice.

A victorious smirk spread across Beca's face as she realized the blonde was agreeing to her plan.

So when do I get to open my birthday present," Stacie tried to ask casually as she watched her girlfriend clean up the kitchen from her birthday breakfast.

A sly grin spread across Aubrey's face. "I told you, not until after dinner with Beca and Chloe."

The brunette let out a frustrated groan. "Can't I just open it now, rewrap it and act surprised when I open it later?"

"Who said your present is something you can open?" Aubrey asked cockily before disappearing into the bathroom, leaving Stacie with her jaw hanging open on the couch.

After the initial conversation, Stacie didn't have much time to think about opening her present because Aubrey had kept their day jam packed with activities that started at the Barden museum of science to lunch at Stacie's favorite sushi restaurant to a couples massage.

When the brunette and blonde came back to Aubrey and Chloe's apartment, the shorter brunette and redhead were already in the process of coking the burgers they would be having.

A large smile spread across Chloe's face when she saw her roommate and her girlfriend walk through the door. In a matter of seconds, the redhead had made her way from the kitchen to the living room to wrap her arms around Stacie's waist. "Happy Birthday Stacie!" She squealed.

Stacie smiled before returning the hug. Chloe was so damn cute. "Happy birthday to you too Chlo."

"Has Bree given you your present yet? She's been teasing me all week, saying it's going to be the best gift she's given me in the 16 years we've known each other."

Chloe and Stacie missed the warning glare Beca shot at Aubrey.

"No she hasn't. She's been totally tight lipped about my present. No hints or anything. I practically tore the place apart looking for it while I was waiting for her to get home from work yesterday." Stacie said sadly.

Before Chloe or Aubrey could say anything about Stacie digging through their stuff, Beca cut them off. "Chloe and I are almost done with dinner, Stacie and Aubrey; why don't you guys set the table?"

Stacie tried to set the table, only to have Aubrey rearrange everything once she was done.

The four sat eating their dinner while the birthday girls told each other what their girlfriends had done for their birthdays.

When they were done, Aubrey and Beca cleaned up while Stacie and Chloe turned on a random reality show.

"Are we really going to do this?" Beca whispered to Aubrey while drying a plate.

The blonde raised a concerned eyebrow at the brunette. "Yes, we are," there was a moment of silence before she continued. "Unless you are really truly uncomfortable, because if so you need to tell me now."

Beca thought for a moment. Aubrey was her friend, she wouldn't do anything to hurt her. They were doing this for Chloe and Stacie's pleasure, not cheating on them behind their backs. "No, I'm not backing out, just a little nervous, I guess."

Aubrey gave the brunette a reassuring smile, "Me too, but I know my girlfriend and my best friend, they'll love it."

"I'm sure they will," Beca agreed as she returned the blonde's smile before following her into the living room. "Beca and I have to get your gifts read in my room, we'll come get you one we're ready," Aubrey said authoritatively before making their way to her room and closing the door.

The blonde and shorter brunette emerged moments later to their girlfriends' mouths wide open while they ogled Aubrey in red lingerie and Beca in black.

The girls straddled their girlfriends before pulling them in for heated kisses before pulling them to their feet and leading them to Aubrey's room and sitting them down in chairs facing the bed. Chloe was the one to break the silence. "Um, Beca, Bree what's going on?"

"Beca and I are going to have sex while you two watch," Aubrey said casually.

"Best birthday present ever," Stacie whispered as her eyes dialated.

Aubrey smirked before pulling Beca into a brief, but heated kiss. When they pulled apart, the girls had to stifle a laugh at how turned on their girlfriends already were. "So, here's how things are going to work," Aubrey said authoritatively. "Beca and I are going to have sex on the bed. You two can call out what you want to see us do, but you cannot touch us or each other, only yourselves. Are we clear?"

Both girls nodded as they started unzipping their pants and sneaking their hands into their underwear. "I want to see Beca on top," Stacie said with a husk. Chloe only moaned at the suggestion.

Beca smirked as she turned around and pushed the blonde onto the bed before moving to straddle her waist. Aubrey let out a soft moan when Beca started grinding in her lap. Loving the reaction she was getting at that point, Beca bent down to kiss and nip Aubrey's neck while whispering teasingly in her ear. "Look at dominant control freak Aubrey Posen reduced to a whimpering mess under me."

All Aubrey could do was buck her hips up to meet Beca's. The brunette pulled the blonde in for a kiss as she reached behind her to undo her bra.

Three distinct moans could be heard as Aubrey's chest came into view. As mesmorized as Beca was by the blonde's breasts, she forced herself to concentrate on removing the article before tossing it in Chloe and Stacie's direction.

Beca wasted no time in latching her mouth onto Aubrey's left nipple, sucking and nipping it to a stiff peak before turning her attention to the right nipple. When she was done, Beca started licking her way down Aubrey's toned stomach to the top of her panties.

Right as the brunette was going to rip the blonde's panties off with her teeth, the distinct cry of Chloe's orgasm could be heard, making all three women stop what they were doing and watch the redhead ride out her orgasm.

"Why'd you stop?" Chloe asked when she opened her eyes and saw everyone was looking at her.

Beca immediately turned her attention back to Aubrey, pulling her panties off and tossing them at Chloe and Stacie like she had the bra.

After settling herself between Aubrey's legs, Beca started mercilessly teasing the blonde, teasing her folds and occasionally dipping the tips of a finger in. At first, Aubrey enjoyed the feeling of Beca's tongue and fingers, but quickly got tired of the teasing without any pleasing and forced Beca's face into her crotch.

The action had caught Beca off guard, but she recovered quickly as she wrapped her arms around Aubrey's thighs and set to work. Her actions were clearly appreciated as the blonde started moaning in time with the movements of Beca's tongue.

"Beca, suck her clit," Stacie called out.

The brunette did as she was told before inserting three fingers to replace her tongue. Aubrey let out a long, low moan at the new feeling as her walls started clamping down on Beca's fingers.

Suddenly, a yell could be heard as Stacie threw her head back in pleasure and frantically fingered herself to ride out her orgasm.

Watching her girlfriend come from watching her and her best friend's girlfriend while her best friend and girlfriend watch them was ultimately what drove Aubrey over the edge, followed quickly by Chloe.

Beca helped Aubrey ride out her orgasm and gave her clit a little nip, making the blonde yelp, as she pulled away. "So how'd we do? The brunette asked, turning her attention over to the taller brunette and redhead.

"Best birthday present ever," a very satisfied Stacie moaned as she pulled her pants up and made her way over to the bed to join her friend and girlfriend.

"My thoughts exactly," Chloe said as she followed Stacie's lead, joining the other three on the bed.

"The real question is, are you two ok?" Stacie asked, concerned.

"How do you mean?" Beca asked.

"Like mentally, psychologically. You guys just had sex outside of your relationships while your girlfriends watched. It would be understandable if you guys felt a little weird after."

The blonde and brunette went silent while they thought back on everything that had just happened between them.

Beca was the first to break the silence. "I feel said."

"Why's that?" Beca asked.

The brunette looked around at the three other women in the bed before beginning. "I had so much fun planning this with Aubrey and even more fun doing it that I'm sad it's over."

The taller brunette, blonde, and redhead all looked at each other before nodding at each other, "Beca what would you said if this didn't have to end?" Chloe asked.

Beca's eyes went wide and immediately looked around at the three other women in the bed. "Really?"

"Maybe," Chloe said sternly. "Now is neither the time nor place to have that conversation, tomorrow over coffee and breakfast. Right now, you and I are going to my room to enjoy one-on-one birthday sex and allow Aubrey Stacie to do the same."

Beca followed the redhead as she led her by the hand out of the blonde's room, closing the door behind her.
