Disclaimer: I don't own Glee, obviously. There will be public sex in this chapter. Don't like, don't read. All of the chapters will be tied together around the idea of trying new things sexually that are outside of the characters comfort zone and will most times be something they have never tried before.

A shout out to Gleeker21 who got my brain whirling with this prompt! Hope you enjoy!

This series is tied together by the idea of how the characters view themselves sexually. Are they vanilla? Or are they excited by new experiences? This is the theme and will be briefly mentioned in each chapter as they go through their journey together.

BTW-Quinn and Rachel are seniors in high school and 18 years old in this fic. I just can't write underage kids getting it on.

I give you chapter 4. I apologize for any mistakes.

Vanilla Sex?

Part 4

Quinn watched Rachel across the choir room as she played the piano and sang quietly, sometimes stopping to scribble on a piece of paper that rested on top of the piano. Quinn couldn't find her more adorable. 'Why does she always have to look so sexy?' Quinn thought.

Quinn glanced around the choir room. Brittany, Mike, Tina and Santana were doing dance moves in the back of the room. Sam and Mercedes were talking quietly to themselves while Puck and Lauren made out behind them, oblivious to everyone. Artie and Finn were playing something together on the guitar and drums, trying to find a good rhythm. It seemed everyone was occupied with something. Even Kurt sat alone texting furiously on his phone, no doubt to his cutie Blaine who attended another school. Mr. Shue was running late as usual and everyone took this time to do their own thing.

Quinn silently stood and walked toward Rachel, quietly slipping behind her onto the piano bench, her legs straddling Rachel's and her front pressing against Rachel's back.

Everyone knew they were exclusively dating so Rachel felt comfortable with Quinn being so close and enjoyed the feeling of Quinn's arms wrapping around her waist. Rachel smiled and looked back at Quinn. "Hey baby. Are you or are you not supposed to be rehearsing right at this moment?"

Quinn smiled even larger. "I am, but you looked so sexy from across the room I decided to come over."

"You really should be practicing Quinn." Rachel replied, turning back to the piano.

"Show me how to play?"

"What?" Rachel asked slightly shocked.

"Show me how to play a song on the piano."

"Umm…" Rachel started, but stopped when she felt Quinn's hands resting on top of her own ready to follow Rachel's lead.

"Show me." Quinn whispered in Rachel's ear.

"This is the song I'm currently working on." Rachel whispered back as she moved her hands along the piano keys, feeling Quinn's hands moving with hers as she struck each note.

"Sing the song." Quinn requested again so quietly only Rachel could hear her.

Rachel didn't reply, instead she began to sing the song she had been working on for Nationals this year.

It was harder than she thought it would be to keep her voice steady and continue playing the correct keys on the piano. She could feel Quinn's breasts pushed against her back, soft hands that rested on her own and the warm breath that softly hit her ear.

Rachel started to grow wet and her body started to tense. Quinn could feel Rachel's body change, becoming stiffer. She hoped it meant what she thought it did.

Again Quinn glanced around the room. Did she dare? It would be so easy to touch Rachel intimately in the crowded room, but also so dangerous. Making up her mind she slowly slid one of her hands down Rachel's side and onto her thigh. Rachel tensed up even more and stopped playing and singing.

"Quinn, what are you doing?" she asked quietly, her wetness pooling in between her legs from her arousal. She was so turned on, but certainly couldn't risk the others finding out what she was feeling.

Quinn slipped her hand under Rachel's skirt and underneath her panties. She placed her lips right at Rachel's ear as she spoke in a hushed tone. "No one is watching. No one will notice. Just keep playing and let me make you feel good."

"Quinn…" Rachel said breathlessly, enjoying the feeling of Quinn slowly circling her clit with her fingers, but terrified of getting caught.

"You said you liked to try new things baby. This isn't vanilla is it? Me touching you like this in front of everyone?"

Rachel just shook her head no, her arousal beginning to take over.

"It's a little exciting, don't you think?"

Rachel nodded her head yes this time, her eyes darting around the room to make sure no one was watching.

Feeling confident they were fairly secluded Rachel pressed up slightly against Quinn's hand, encouraging her to explore further.

Quinn smirked against Rachel's ear. "Keep playing and singing baby. No one will notice, I promise."

Rachel glanced around the room once more before returning her fingers to the keys and starting to play, softly singing the words as best as she could.

Quinn kissed the back of her neck twice and continued to dip her fingers in and around Rachel's opening before dragging them back up to rub at her clit. Rachel began to tense again and slightly shake, but continued to play.

As Quinn worked Rachel's body higher and higher, Rachel started to sing louder and louder. Not to the point that anyone would really look up and notice, but loud enough that her voice could be heard from across the room.

Rachel continued to play and sing, occasionally pushing herself into Quinn's hand or swirling her hips slightly to increase the pressure.

Quinn inserted two fingers and brushed Rachel's clit with her thumb. Rachel's walls tightened around her.

Rachel came hard, her body arching backwards into Quinn, and her voice cracking mid note.

The room fell silent. No one had noticed Quinn and Rachel's intimate sexual encounter, but they had certainly noticed that Rachel Berry had sung out of tune. Rachel's face was flush from her recent release and she could feel all of the glee clubs eyes on her. She felt embarrassed, but she felt oh so good too.

Quinn tried to quickly cover the situation by letting out a slight chuckle. "I probably shouldn't have tickled her." She stated to the room, trying to explain Rachel's cracked note, hoping everyone would accept her explanation and move on.

"Yeah, TICKLED her." Santana replied sarcastically, "If you're going to get it on at school, go to the janitors' closet like everyone else."

Brittany just nodded her head in agreement and added, "Not that it isn't hot or whatever. Once San and I….." but Santana had quickly covered Brittany's mouth before she could finish her sentence.

Finn finally figured out what was going on and became wide eyed. "You mean, you guys just, oh my God. Mailman, mailman, mailman."

"I don't know what you all are talking about." Rachel said, blushing even deeper. Feeling a little more confident she stood up and grabbed her stuff. "I'm going to continue my writing at home if that's ok with everyone." she stated as she began walking towards the door, "Quinn are you coming?"

"I don't think she has yet Berry, but you certainly did." Santana said, raising her eyebrow at Rachel and smirking. Rachel just huffed, turned on her heal and walked out of the room.

Quinn finally got up to follow Rachel, but felt Santana grab her arm just as she was walking out of the door.

"Nice Fabray, I never would have pegged you as kinky." Santana winked at her and let go of her arm, "Go get your midget."

Quinn rolled her eyes at Santana as she left the room and ran into the hallway looking for Rachel, only to find it empty. 'Rachel must really be upset' she thought as she started to walk towards the front doors of the school.

Just as she began to walk past the auditorium she felt a hand grab her shoulder and pull her into darkness. She felt her back being pushed up against the door and her eyes focused on Rachel's face.

"I'm sorry Rach. I honestly thought no one would notice."

Rachel just leaned in and kissed her hard. "You've had your fun baby, but now it's your turn to be center stage. "

Quinn's eyebrows rose in confusion. She had no idea what Rachel meant, and she didn't even seem pissed off that a room full of their friends had found out they had sex right in front of them.

"Rachel, the glee club is coming to rehearse in here literally any minute now."

"Exactly," Rachel said as she grabbed Quinn's hand and led her to the stage. "We'll just have to be quick. No one will even notice, I promise." Rachel looked back and smiled a sexy smile, shooting a quick wink at Quinn.

Quinn swallowed hard as she quietly followed Rachel onto the stage. She hoped Rachel was right, but then again she was too turned on to care.

Ok guys, I purposely left this one open so YOUR minds could fill in the blanks to what happens to Quinn. Are they caught again, or do they get away with it this time? You tell me what you think.

This was a bit of a teaser chapter (I'm not 100% happy with it), but I just couldn't get it out of my head. Next chapter, hmmm I have a few ideas. Hit me up and shoot me a review! Two updates in two days. How can you not love that?

A/N- This series was intended to just be a two-shot but has developed into much more. I enjoy your prompts and will try and fulfill them as best as I can, but the point of this story is not JUST smut. I intend to write this based on an inexperienced couple becoming comfortable with each other sexually and trying new things. Sometimes things will get a little hardcore, but I will always try and keep it light and not write anything too extreme. Rachel and Quinn are just discovering themselves, and their likes and dislikes by trying new things, so they will switch back and forth with who is dominate and who is submissive. I know most of you have preferences, and I will try and meet them as best as I can.
