Finn had been having a nice quiet day with no girl drama whatsoever so it really should not have come as a surprise to him when he found himself bodily hauled into an empty Biology classroom on his way to his Physics lab. Once the door had been barricaded behind him Finn found himself facing both Rachel and Quinn with determined looks on their faces and he realised he would much rather be facing a firing squad. "Finn, do they know?"

"No." Finn answered far too quickly. He realised his mistake as soon as Rachel and Quinn raised their eyebrows at him. Not only had they not said who 'they' might be but also they had not said what 'they' might know. He sighed in defeat and then admitted it. "Yeah Brittany and Santana know about you two."

Rachel gaped at Finn in disappointment. "Finn! I cannot believe that you told someone about us, least of all Brittany and Santana! What were you thinking?"

Finn folded his arms across his chest and gave Rachel a wounded look. "Hey! I didn't tell them anything. I promised I wouldn't say anything and I didn't!"

"How did they find out about us then?" Quinn demanded.

"They saw you doing it in the Astrology room."

"Astronomy room." Rachel absently corrected.

Quinn glared at Rachel. "That's what you choose to focus on?"

Rachel folded her arms and returned Quinn's glare. "I told you we should have been more careful after he caught us."

Quinn raised her arms defensively. "Hey, you could have stopped it at any time."

Rachel pointed at Quinn accusingly. "Well it is quite difficult to concentrate on anything else when your hand is shoved up my skirt!"

"It was your idea to have sex centre stage Ms. Exhibitionist!"

Rachel blushed. "I think we're getting off topic."

Quinn nodded her head in agreement and then an idea entered her head that had her grinning in the way that made Finn incredibly uncomfortable. "They don't know that we know!"

Rachel smiled at her girlfriend in the way that terrified Finn. "Ah yes, now we can turn the tables on their Machiavellian scheme!"

Finn looked between the two very scary girls he used to date and realised that he needed to make safer life choices. "Can I go now?"

Rachel's eyes were locked on Quinn's but she absently indicated Finn could leave with a wave of her hand and Finn bolted out of the room. Rachel walked over to her girlfriend and pulled her into an embrace. She then whispered in Quinn's ear. "I'm several weeks ahead in AP History if you're interested in doing some Machiavellian plotting of our own?"

Quinn shivered at the contact and the feel of Rachel's warm breath against her ear. She reached down and brushed the bangs out of Rachel's eyes. "Baby, I could plot with you all day and all through the night."

Rachel's mouth formed a predatory grin. "I'm intrigued by your ideas and wish to subscribe to your newsletter. Perhaps you could elaborate on your ideas at length in the janitor's closet?"

Quinn nodded her agreement and dragged Rachel out of the Physics lab towards the nearest janitor's closet; they were both absent from class for the rest of the day.

Brittany and Santana had been the first ones to arrive for that day's Glee practice so that they could try and puzzle out what to do for their psychobilly assignment while Finn sat trying to solve a puzzle on his Nintendo DS.

Brittany's mobile rang and once Santana reminded her how to answer it she answered it with a bounce in her step. "Hello?"

"Hello Brittany. I've been thinking about you all day." Rachel purred through the phone.

Brittany froze. "You have?"

"Yes, I've had time to think about your offer and I've decided that I am most amenable." Rachel gave Quinn a satisfied smile to which Quinn responded with an eye roll and mouthed. 'You're talking to Brittany!' Rachel quickly added. "By which I mean I've thought about what you said earlier and I'm up for dessert and maybe you could rip off one of my skirts too!"

Brittany panicked; this was not how she had expected this to go. Sure, she found Rachel hot underneath those awful clothes but she and Santana were trying to be Proper Girlfriends now, which meant no sex outside dating. "Uh, can I get back to you?" She asked Rachel before hanging up the phone. "San, Rachel wants me to rip her skirt off and have me for dessert!"

Santana shot up from her seat in a rage. "I cannot believe Trumpkin would do that to Quinn, I'm going to kick her ass so hard…" Santana trailed off in her ranting when she saw Finn desperately trying to look anywhere other than at her. "Finn, do they know we know?"

Finn squirmed under Santana's intense gaze. "…No."

"Finn." Santana warned in a menacing tone.

Finn crumbled like a cheap cookie. "They know, you know."

Santana scoffed. "Those two thought they could screw with us? They've got nothing on us when it comes to sexual manipulation!" Brittany nodded her head in agreement with Santana as the Latina came to a delicious conclusion. "They don't know that we know they know we know."

Brittany turned to Finn and gave her best shot at an evil glare. "You can't tell them Finn."

Finn shrugged. "I am so tired from trying to understand what's going on my head hurts and I just want to go to sleep."

The rest of the Glee Club chose that moment to enter the choir room, as everyone settled into their seats on the risers and began to idly chat Rachel hung back by the piano organising sheet music and wearing a triumphant smirk over her successful attempt to nonplus Brittany.

Rachel was so pleased with herself that she did not notice the blonde dancer approach her and casually lean against the piano, getting all up in Rachel's personal space. Brittany leaned in to whisper breathily in Rachel's ear. "What you said earlier? I'm totally in. How about dinner tonight?"

Rachel tried to disguise her surprise as well as the shiver that ran through her at the look Quinn was giving her with Brittany so close she could feel the girl's hot breath on her neck. "Really?"

"Sure!" Brittany chirped. "Is seven good for you?"

Rachel knew that Brittany was upping the ante and that if she and Quinn were going to win she needed to respond in kind. "That is a perfectly acceptable time, in fact my Dads are out tonight so if you come to mine we will have the house to ourselves."

Brittany smiled, as she realised that it was on. "Cool, do you want me to bring San?"

Rachel gulped at the idea of trying to handle both Brittany and Santana at the same time. "Not on this occasion Brittany."

"Are you sure?" Brittany asked before adding seductively "I know how much you love an audience."

Rachel almost choked on nothing but air. "Maybe another time." Brittany flounced off to her seat and Rachel turned to give Quinn a scandalized look to which Quinn responded with one of her patented eyebrow raises. It had taken a great deal of time and study on Rachel's part but she had eventually decoded the meaning behind each of her lover's eyebrow raises. This particular one was to remind her that she was currently giving the game away so Rachel turned back to the piano to focus herself.

Mr Schue continued to demonstrate his sense of timing by choosing that moment to enter the Choir Room and usher Rachel into her seat next to Artie and start practice.
