Chapter 22 - It's Hard to Grow Up

"So… our sweet little boy is about to start a crash course in potty training," Quinn told Rachel the minute the singer had stepped through the front door after being at the studio for most of the day.

Rachel raised her eyebrow questioningly. She kissed her girlfriend on the lips then sat down next to her on the couch. "Oh yeah? What happened?" she asked, lacing their fingers together.

"I caught him peeing in the backyard," Quinn stated, not at all happy.

Rachel had to quickly stifle the laugh in her throat. She knew Jaxon wouldn't be the only one in trouble if Quinn found out that she had already witnessed their son's peeing expeditions in the backyard. "Oh yeah?" she asked innocently.

"Yes. Britt and I were in the backyard with Jaxon today. She was teaching him some ballet sequences when he just stopped midway through and ran over to the tree. Then your son proceeded to take off his diaper and pee on the tree."

Rachel bit her lip, holding in her smile. Her kid was totally awesome! But of course Quinn couldn't know about that. "That's horrible!" she tried inserting a shocked tone.

"My point exactly!" Quinn exclaimed. "So… you and I are going to the store today to buy him some pull-ups, underwear and everything else he's going to need to learn how to use the toilet."

~~~~~QR~~~~~

Rachel tossed several packs of underwear for Jaxon into the shopping cart, then walked away again.

Curious, Quinn picked up one of the packs and laughed. Of course Rachel would get little boy underwear with music notes on them. And then there were two packages of music instruments underwear, and two with microphones and guitars. There was also one with…

"Hold on, Rach," Quinn said as the singer approached the cart again, dropping in a few more things. "We can't get him these."

Rachel looked at the package of underwear her girlfriend was holding up. "Why not? He loves watching 'Frozen'."

"Yes he does," Quinn agreed. "But these are girl underwear."

"But I couldn't find any 'Frozen' boy underwear," the brunette defended.

"But girl underwear is very fitted and doesn't provide the… extra space that a boy needs."

Rachel looked confused for a split second then her eyes widened. "Okay, I am officially an idiot. Sorry, my brain must be on meltdown, it's been a long week at the studio," she said sheepishly as she took the girl underwear and walked off to return it to its rack.

"And what is this for?" Quinn asked, holding up a jumbo package of M&Ms.

"Hello! Target practice!" Rachel exclaimed.

Now it was Quinn's turn to look confused.

Rachel explained, "You put a couple in the toilet and Jaxon will aim for them. It's a fun game for boys."

The blonde rolled her eyes. "That reminds me – you are the one who gets to potty train Jax."

"What?!" Rachel exclaimed, her eyes wide.

"You heard me," Quinn stated.

"But… Why me?" Rachel whined.

Quinn stood in front of the brunette with her hands on her hips in a stereotypical HBIC pose, her eyebrow perfectly arched. Whenever Rachel saw Quinn with that expression on her face, she could just imagine what the blonde was like in high school. No doubt everyone was scared piss-less of her.

"Because, Rachel," Quinn explained, "You have a penis… he has a penis…"

Rachel threw her hands in the air and exclaimed, "So what?! That automatically makes it my job to potty train our son?"

"Yes," Quinn stated firmly, end of discussion. But when she saw the same stubborn look in Rachel's eyes that she so often saw in Jaxon's, she knew she wouldn't convince the singer by sheer force. She needed to be smart about this, make it seem like the potty training was in Rachel's best interest. "I'm sorry, Rach," she said sweetly as she ran her hand down Rachel's bare arm, wanting to lower the singer's defenses.

Rachel sighed and closed her eyes, willing the arousal that shot through her body by just that simple touch to go away. She open her eyes to see her girlfriend inches away from her, fingertips still stroking her arm.

"Please, Rach. I'll make it up to you," she purred.

Rachel knew she was being played, but one look into those soft hazel eyes and her resolve evaporated.

"Arggg! Fine," the diva gave in. "But I expect an all-nighter from you."

~~~~~QR~~~~~

"Jaxon! Come in here please!"

Jaxon ran into the living room when he heard his mama calling. She was sitting on the couch so he crawled up into her lap and gave her a kiss on the cheek. "Hi, Mama! You go shopping?" he asked, looking at all the shopping bags on the floor.

"Yep. And Mom 'Chel and I bought you some things."

His eyes lit up. "Presents?"

Rachel walked over and sat down next to them. "Kind of." She opened one of the bags and pulled out a package of new underwear and showed it to Jaxon.

The little boy's eyes widened. "Drums!"

Quinn opened the package and held up the instruments underwear. "These are your new underwear," she told her son.

At the word 'underwear', Jaxon's excitement instantly deflated. "No," he stated firmly.

"Jaxon," Quinn said sternly. "Remember when you peed on the tree and we talked about how it was time to be a big boy and use the toilet?"

He crossed his arms and pouted. "No. No toilet. Just 'iaper."

Rachel pulled him out of Quinn's arms and set him on her lap. "Oh come on, Jax. I have a few games we get to play to make it fun."

Still pouting, he shook his head. "Un'wear boring."

"Oh yeah?" Rachel smirked as she reached down and pulled a certain pair of underwear out of one of the bags and held it up for her son to see.

Jaxon's eyes widened and his jaw dropped. "'Reen? 'Itch hat?" he asked in awe.

Rachel chuckled. "Yep. Your mama and I stopped by a very special person's house, and lo and behold, she happened to know you loved the color green and witches hats and broom… so she had bought you some underwear and was saving it for when you were ready." She looked at him with a raised eyebrow. "Was she right, are you ready? Or should I give them back to her?"

Jaxon shook his head furiously. "No! No, I wear!" he exclaimed, he tried to grab them from Rachel's hand, but the singer pulled them out of reach.

"Nuh uh. Only boys who use the toilet get to wear them."

Jaxon stared at Rachel, then over to the underwear. He looked at Quinn as he bit his bottom lip, weighing the options. Freedom to pee anytime OR green underwear? Big decision.

Finally he took a deep breath and sighed, his shoulders drooping. "Fine. Pee in toilet."

~~~~~QR~~~~~

Quinn was jolted awake in her bed when a body landed on top of her. Normally it wasn't a big deal since it was usually just Jaxon, but this body was definitely much bigger than a three year old's. Then the bouncing started, and her own groaning began, "Go away."

"Good morning, Quinn!" the high pitched voice cut through the air.

The blonde rolled her eyes and sat up, pushing her younger sister off of her. "Charlie, what the hell are you doing here so early?" she grumbled, flicking a few pieces of unruly bed-hair out of her face.

The younger blonde looked offended. "Excuse me? I have been out of town for months! So sue me if I wanted to immediately come see my old, old sister – who by the way, looks like hell."

Quinn glared at the smirk on Charlie's face, then slid out of her bed and headed toward the en-suite bathroom.

"I don't even get a hug and an 'I missed you, Charlie'?" the young girl called out.

"Not until I have a cup of coffee!" Quinn responded.

Charlie huffed, then grinned as she jumped off the bed and ran to her nephew's room. She knew at least he would be happy to see her.

After Quinn took a shower to wake up, she threw on some shorts and a tank top and made her way to the kitchen. She had to laugh when she saw her son and her sister in a full on tickle fight. She knew Jaxon loved playing with Charlie, but it had been so long since he had seen her, Quinn was worried he wouldn't remember her. But by the look of pure happiness on his face, she need not have worried.

"Good morning, you two," Quinn called out as she opened the cupboard to grab two coffee mugs.

"Mama! 'Arlie back!" Jaxon squealed, throwing his arms around his aunt's neck and peppering her cheeks with kisses.

Quinn chuckled. "Yes she is. And I for one am very happy." She set the mugs on the counter and crossed over to her little sister and enveloped her in a warm hug. "Welcome home, sis. I really did miss you."

"Oh! So now you're happy to see me!" Charlie teased. "It didn't sound like that 20 minutes ago."

Quinn pushed away and walked back over to fetch the coffee mugs. "You know better than to interrupt my sleep!" she defended. "Anyway… do you want some coffee?"

Charlie nodded. "So… what's been happening since I've been gone? Someone only sent me a handful of texts the whole time!"

"Hey! I knew you were safe!" Quinn defended herself.

"Yeah, only because I texted you at least once a week!"

"So sue me, okay! I've been busy!" the older blonde laughed as she poured the two coffees, making sure to put extra milk in Charlie's, just the way she liked it.

"Doing what? Categorizing lame pieces of artwork and socializing with rich snobby antique collectors?" Charlie said, rolling her eyes as she accepted the coffee from her sister.

"No. Hanging out with Rachel."

"Rachel who?" she asked, taking a drink of her coffee and raised her eyebrow in true Fabray fashion.

Quinn smirked, "Rachel Berry."

The only sound in the kitchen was the spewing of Charlie's coffee all over the table. "WHAT?!"

"Gross, 'Arlie!" Jaxon made a disgusted face at his aunt then went back to his cereal.

Quinn laughed. "You heard what I said."

Charlie gasped loudly and shot her hand up to cover her mouth. "What the hell-"

"Bad word!" Jaxon exclaimed, looking over at Charlie. "Mom 'Chel says I no say bad words."

"Your mom is right. Bad words are bad," Quinn told him, running her fingers through his slightly messy brown locks.

Charlie's eyes were as big as saucers as she looked back and forth between her sister and nephew. She couldn't believe they were talking about Rachel Berry like it was no big deal having the singer in their lives. "Now we're talking about the Rachel Berry right? As in, the-best-singer-in-the-world-member-of-the-hottest-band-I-would-bed-her-immediately-if-I-swung-for-that-team-yet-she-fathered-my-sister's-baby-Rachel Berry?!"

Quinn rolled her eyes and took another sip of the hot coffee. "That would be a 'Yes'."

"Quinn Fabray!"

"Charlie Fabray!" she mocked her sister and smirked as Charlie stood up and paced the kitchen floor.

"You're not kidding, are you?"

"No, I'm not," Quinn laughed.

The young blonde's breathing seemed to get heavier and heavier. "I think I'm gonna pass out," she said, her hand covering her forehead.

Quinn just stared at her sister in confusion. "Charlie, why the hell-"

"Mama! Bad word!" Jaxon called out, finishing his cereal. "Me play now?"

She turned and saw that he had, surprisingly, eaten his entire bowl. Nodding, she lifted him out of his high chair and watched as he ran into the living room. She looked back at her odd sister and asked, "Charlie, why is this freaking you out?"

"Because it's Rachel Berry!" Charlie exclaimed like Quinn was dense.

"You've known for years that she is Jaxon's other parent."

"Yeah. I know," she said. "But… Q, I know what she did to you back then was shitty. Really shitty. And I know that deep down, even though you didn't want anyone to see it, you have always loved her. You have secretly wished for years that she would come back into your life."

Quinn just stared, slack jawed, at her sister. "How did you know that?"

It was now Charlie's turn to smirk. "Because I'm your sister, dumb ass. I see through you a thousand times better than even Santana does."

Quinn smiled. "Of course you do. It's always been just you and me, huh kiddo?"

"Yep," Charlie answered. She grabbed an apple out of the basket on the counter and took a big bite. "Besides, the main reason I am so stoked is because… Hello! Rachel Berry is the hottest rock star in the world!"

Quinn couldn't help but laugh at the stars she saw in Charlie's eyes. "Of course you would have a girl crush on Rachel Berry. I should have known."

"Dude, New Directions' music is awesome! It just gets better with each album! I would have to be dead not to have a girl crush on her like every other female in the world!"

The other blonde was about to reply when her phone rang. She grabbed it from the counter and saw that it was Rachel. She smiled up at Charlie. "Speaking of the sexy devil…" She pressed Answer, "Hey, Rach!"

She giggled when she saw her sister's eyebrows hit her hairline and her jaw hit the floor.

"Good morning, Quinn," Rachel smiled through the phone. "I was wondering what you and Jaxon were doing today? If you already had plans?"

"Our day is completely open. I took the next few days off to spend time with Jaxon. So we don't have any plans."

"Good."

"Oh! And guess what? My sister Charlie surprised me this morning. She's back from Europe!"

"That's great! Do you all want to go out for ice cream or something?"

Quinn grinned. "Sure! That sounds wonderful. I know Jax would really love it, especially being able to spend more time with you. And I'd love to introduce you to Charlie."

"I can't wait to see him too," then she paused. When she spoke again, her voice was slightly deeper, "But he's not the only one I'm excited to see. You have been on my mind all night… and morning, Quinn Fabray. Being woken up this morning from a… very vivid dream I was having was a huge disappointment. I wanted to stay in it forever."

Quinn blushed, then stepped out of the kitchen so Charlie wouldn't overhear. "Oh yeah? What was so… vivid about it that you wanted to stay asleep?" she flirted.

"It was definitely something I can't explain," the singer husked, causing Quinn's sex to tighten. "Perhaps I can… demonstrate it to you sometime. Actions speaking a lot louder than words, and all that."

"Shit…" was all the blonde could mutter, her mind going in all dirty directions.

"So…" Rachel's voice turned back to normal, knowing full well what she was doing to Quinn. And she loved it. "I'll meet you guys at the ice cream parlor by the park in… let's say, 20 minutes?"

Quinn took a deep breath and bit her lip, trying to smother her arousal. "I hate you, Rachel Berry."

Rachel chuckled. "Awww… Are you hot and bothered, Quinn?" she teased.

"I hate you… and we'll see you in twenty." Then she hung up. "Damn sexy singer," she muttered to herself before going back into the kitchen to talk to Charlie.

She told Charlie about Rachel inviting her and Jaxon to go get ice cream. She wanted to introduce Charlie to Rachel, so she invited Charlie along as well. The younger blonde was ecstatic. Even more so than Jaxon when he heard, and that kid gets excited!

~~~~~QR~~~~~

Quinn and Charlie were walking down the street to meet Rachel. Jaxon was bouncing excitedly in his aunt's arms, babbling away to her about his Mom 'Chel and everything they had done together. After telling Charlie about the ice cream invitation, Quinn filled her in on everything that had been happening since she and Rachel met again at the Halloween party. Needless to say, the young Fabray was dumbfounded. But she was so happy that the two women were now on good terms and were building a real relationship together.

The ice cream parlor came into view and Quinn decided she better make sure her sister didn't freak out when she met Rachel. Even though Charlie had known about Rachel and Quinn's… involvement for years, Rachel Berry the rock star was causing her to have fan-anxiety.

"Char?" Quinn said.

"Yeah?"

"You know Rachel is just a normal person right?… I don't want you to go all 'crazy fangirl' on her, okay?"

"I would never!" the younger blonde gasped in a mocking tone which made Quinn roll her eyes.

"Just… chill. Okay?"

"Don't worry, I'll try and stay sane," Charlie laughed.

"Thank you."

They carried on walking until they neared the ice cream parlor and saw Rachel standing outside. Quinn almost stopped in her tracks when she noticed, once again, how insanely beautiful the brunette was. She was wearing simple denim shorts and a blue tank top, accompanied by white converse sneakers and black sunglasses.

Jaxon spotted the singer at the same time. "Mom 'Chel!" he cried out, instantly getting Rachel's attention. "Down, 'Arlie! Me down!"

Charlie set her nephew down on the ground and watched as he ran the last several yards and threw himself into Rachel's arms. Rachel caught him and picked him up into her arms, huge matching grins on both brunettes' faces.

"Oh my… Q, that's Rachel Berry!" Charlie harshly whispered, her eyes never leaving the singer.

Quinn rolled her eyes. "Remember, Char. It's just three normal women and one little monster that is soon to be hopped up and sugar. That's it. No famous singer today. Just us. Okay?" When Charlie nodded, she let out a breath. "Okay. Come on." She grabbed her sister's hand and pulled her over to the two babbling brunettes.

After a few seconds of standing in front of the deeply engrossed brunettes and getting no recognition, Quinn cleared her throat. "Sorry to interrupt you two divas, but… Charlie and I are here."

Rachel pulled her attention away from her son and laid loving eyes on Quinn. "Hey, Quinn," she said, softness in her voice as she pecked her girlfriend's lips.

Quinn blushed. She hated that Rachel could get her flustered so easily. "Hi, Rach."

Their eye sex was interrupted by a loud clearing of a throat.

Quinn pulled away and turned toward her sister. "Oh…uh sorry…Rachel, this is my sister, Charlie. Charlie this is Rachel."

The singer smiled and held out her hand to the girl who looked remarkably a lot like Quinn. "Hi, Charlie. It's nice to meet you. And welcome back."

Charlie's eyes were huge as she stared at the famous rock star. Quinn nudged her to shake her from her trance. "H-Hi. It's…nice to meet you too…Rachel," she sputtered, shaking the proffered hand.

"Mom 'Chel?" Jaxon said, wanting to get Rachel's attention back on him. "Ice cream peas."

Rachel chuckled then nuzzled her nose in the little boy's neck, making him squeal. "Oh… you want ice cream, do you?" He nodded enthusiastically. "Well, let's go then. Let's see what kind of special ice cream they have for Mr. Jaxon Fabray." She turned to walk into the parlor, but not before lacing her fingers with Quinn's, causing the blonde's heart to beat faster.

Fifteen minutes later, they were sitting at one of the outside tables eating their ice creams and enjoying the sun. Jaxon finally decided on chocolate fudge ice cream in a cone. Charlie got blueberry cheesecake in a bowl. Rachel decided on a simple tropical fruit ice cream cone. And Quinn got a caramel fudge with chocolate sprinkles. Rachel paid for all of the ice cream, regardless of Quinn's protests.

"So, do you have anything else planned for today, Rach?" Quinn asked, slipping a spoonful of ice cream into her mouth.

Rachel gazed at the beautiful blonde. "Not a whole lot. Just maybe writing some lyrics for a new song. Oh, and I have to meet up with a new artist down at the studio. But it should only take an hour," she said, her eyes flicking over to see that Charlie was distracted with teasing and playing with Jaxon. She held her ice cream cone and slowly licked a wide lick from the bottom of the ice cream to the top, softly moaning so only Quinn could hear.

Quinn swallowed hard as she watched Rachel erotically lick her ice cream. She knew that the singer knew exactly what she was doing to her, but for now she didn't care. She just stared openly at Rachel's soft pink tongue as it lathered up another lick and disappeared into her mouth.

"What about you?" Rachel asked, a sly grin growing on her lips.

"Huh…W-What…?

"I asked if you have any other plans for today?" she husked, quietly. Sending a jolt through Quinn's body.

"I uh…no. No, we do not," she managed to get out. "But I do recall making a promise to a certain brunette who said she would potty train a little boy."

Rachel smirked and gave her girlfriend a kiss. "Yeah, I need to collect that promise soon."

When Rachel finished her ice cream, she grabbed Quinn's feet and brought them up to rest on her lap, and began to massage them.

Charlie and the singer fell into a discussion about the best dance clubs to go to in the city. Rachel agreed with most of the blonde's choices, but added a few more hot spots to the list.

"Sparkage?" Charlie asked. "I haven't heard of that club."

Rachel looked at her incredulously. "Seriously?! You haven't heard of Sparkage? Have you been living in a hole?"

Charlie laughed. "I've been in Europe, remember? Duh."

Quinn had to giggle. It was great seeing Rachel and Charlie getting along and becoming friends.

"Of course, of course," Rachel said. "Good point. Well, the guys and I are heading there this weekend. You two should join us. We can even hang out in the VIP area." She smiled over at Quinn and squeezed her hand. "Peas," she pouted, looking everything like Jaxon.

Quinn rolled her eyes and scoffed. "Low blow, Berry. No fair using our son's cuteness against me."

"Hey, whatever works!" the diva exclaimed, giving her girlfriend a seductive wink.
