They two finally pulled up to Murphy's house a half hour late from making out a little too much in the car a couple of blocks away. When they got to the door, they could hear one of Clarke's favorite Machine Gun Kelly songs, nothing inside, blasting from inside the house. When they opened the door someone turned the music down.

"THE PRINCESS IS HERE!" Bellamy yelled as he ran over to Clarke and Lexa.

"Hey Bell." Clarke said giving him a hug.

"Happy birthday Princess."

"What took you guys so long?" Octavia asked walking over with Raven.

"Oh you know, just lost track of time, didn't start getting ready in time." Clarke said shrugging her shoulders as she looked over at Lexa and tried to hide a smile.

Octavia and Raven looked at Clarke suspiciously then looked at each other.

"Well...LET'S PARTY!" Raven yelled.

Everyone laughed, sang, drank, danced, and Clarke opened a couple of presents from people who were leaving the party early. She mostly got new sketchbooks, color pencils, and other art supplies.

Almost an hour later Clarke pulled Lexa aside and whispered something in her ear.

"I can't wait till we get home. I need you now, the third floor last bedroom, like the first time?" Clarke asked as bit her lip.

"We can't. Remember what happened last time?"

"Yes, but you're officially my , and I would very much like to hear my moan as I fuck her."

"I- okay. Wait for me upstairs." Lexa said blushing.

While Clarke went upstairs Lexa grabbed a water and walked back over to her friends.

"Hey where's Clarke?" Bellamy asked Lexa.

"I don't know." Lexa said shrugging her shoulders.

"Probably went upstairs with some guy." Octavia said.

"No, she knows that's not allowed in my house." Murphy said.

"Yeah, but it's not like we all don't do it." Raven said.

"I hate you all." Murphy said looking at everyone.

After a couple of minutes later Lexa excused herself from the group to use the bathroom when really she walked upstairs to the last door to find Clarke on her phone laying on the bed.

"Took you long enough." Clarke said as she got up.

"We couldn't just disappear together." Lexa said as Clarke wrapped her arms around her, "That would be very suspicious."

"What did you tell them?"

"They think I'm in the bathroom and O said you're probably with some guy."

"Nah I'm just with my girlfriend." Clarke said with a big smile then kissed her.

"Girlfriend." Lexa said returning the smile and kiss.

The kiss became heated as Clarke backed her against the door and kissed down her jawline, to her neck. "Off," she said trying to pull Lexa's shirt off.

Once the shirt was off Clarke took the brunette's bra off and palmed the uncovered breasts earning small gasps from her girlfriend. She took one of the nipples into her mouth, sucking and swirling her tongue around it as her hand went up to gently pinch the other.

"Fuck Clarke." Lexa moaned as her hips jerked forward.

She let go of the breasts and kissed Lexa on the lips.

"I wanna taste you," Clarke said slowly kneeling down, kissing the tightening abs as she went, "Can I?"

"Yes, god yes." Lexa practically begged.

When she got down on her knees she pulled down the brunette's pants and underwear.

"If you feel like you can't stand let me know and I'll move you," Clarke said looking up at Lexa who nodded her head.

Clarke spread Lexa's legs a little and moaned when her tongue hit Lexa's center. "Fuck you always taste so good." She mumbled into the brunette's folds, causing a hand to grab Clarke's head.

Clarke chuckled at Lexa's reaction and felt the hand tighten in her hair. She spread Lexa's legs a little wider and took long strides up the slick, wet slit, sucking on her outer lips every once in a while. With one last long stride up, she sucked the brunettes clit into her mouth. Lexa rocked her hips forward, pushing Clarke's head in her center.

The blonde sucked a little harder right before dragging her tongue back down to Lexa's opening and pushed her tongue in. Clarke moaned, not knowing if it was from how much and how good Lexa tasted, or at how rough Lexa was being by accident, tightening her grip to an almost painful amount in the blonde's hair, pushing the blondes face into her center as she rocked her hips forward. As she pushed her tongue inside she grabbed one of Lexa's legs and put it over her shoulder, so she had a better angle.

The feeling of having Clarke's tongue deeper than it ever felt before and Clarke's nose hitting her clit every time she thrust her hips forward, caused Lexa to let out the most pornographic moan Clarke had ever heard, as the hand that wasn't on the blonde, gripped the bookshelf next to them.

"Clarke, oh fuck Clarke." Lexa moaned as she started fucking herself on the blonde's tongue, rocking herself back and forth, not caring about the rhythm Clarke was trying to set. When she felt Clarke's mouth move away she let out a whimper that was immediately replaced with a moan as she felt two fingers stretch her and her clit back in Clarke's mouth.

Clarke curled her fingers forward and sucked the brunettes clit a little harder with each pump. She could tell she found the spot as she felt Lexa's legs start to tremble and her rocking becoming frantic. She looked up to see Lexa holding onto the bookshelf for dear life, eyes shut tight with eyebrows scrunched together, and mouth parted in an almost perfect o shape.

"Are you okay?" Clarke asked when she released Lexa's clit, "Do you need to move?"

All Clarke got in return was the telltale signs of Lexa's orgasm and Lexa's hand pushing her back to her clit. Once her tongue swirled around the swollen nub while her fingers curled forward, hitting the spongey, bumpy texture patch on the brunette's front wall, Lexa's hips stilled.

"Fucking god Clarke...Fuck!" Lexa moaned, coming on Clarke's hand and mouth, her hand still tightly gripped into Clarke's hair, not letting her move, as her head fell back, hitting the door, her legs shaking, her chest heaving, her breathing heavy, and her eyes shut so tight she could see stars.

"I- that- fuck...wow." Lexa said once she finally rode out her high.

She let go of the blonde's hair, letting Clarke finally stand up. Clarke helped pull Lexa's pants up then helped her sit down on the floor, against the door. When Clarke sat down next to her, Lexa immediately wrapped her arms around her waist and put her head on Clarke's shoulder.

"Wow," Lexa said again, earning a laugh from Clarke, "I mean it, wow."

Clarke took one of Lexa's hands and slipped it past her pants, to her completely ruined underwear, "You did this."

"Oh my- Clarke you're so- how?" Lexa asked in shock.

"You, that's how. Watching you, tasting you, hearing you, feeling you, I could cum from just that."

A smirk spread across Lexa's face as she ran a finger over the girl's slit through the underwear, "I'm glad I have this effect on you."

"That smirk definitely doesn't help." Clarke pulled Lexa in for a kiss and felt herself become wetter as Lexa drew lazy circles on the blonde's clit and moan as she tasted herself on Clarke's lips.

"Mmm let's go back to your house." Lexa said

"That is a great idea."

The two girls got up, Lexa left first and Clarke came down a few minutes later. They talked to everyone for a few more minutes, then Lexa gave Clarke a look, who instantly knew what she was saying.

"Hey, guys we're gonna leave." Clarke said to all her friends.

"Aww, why? You've only been here for like a little over an hour." Octavia asked pouting.

"We have to go somewhere tomorrow." Clarke answered.

"Where ya guys going?" Raven asked.

"Uhhh we're gonna go to the mall." Lexa said.

"Okay well one, rude for not inviting us. And two, why do you have to leave so early?"

"Well Lexa is gonna sleepover so we were going to stop by her house to pick some stuff up, and we wanna go out for breakfast." Clarke replied.

"And you're not gonna invite us, disgrace." Raven said shaking her head.

"You, you guys can come if you want, and, and sleepover." Lexa suggested.

"Oh my god yes." Both girls said in unison.

Once the girls got to Clarke's house, Clarke and Lexa sat next to each other on the blonde's bed, letting their pinky's touch.

"So whatcha guys wanna watch?" Octavia said plopping down in between Clarke and Lexa.

"Anything." Lexa said handing Octavia the remote.

"You guys pick while Lexa and I get snacks." Clarke said getting up.

"Who said I was coming with you?" Lexa asked confused.

"If you don't help you don't get any." Clarke said walking out of her bedroom, "I MEAN IT."

"Fine." Lexa sighed getting up.

Lexa walked downstairs to find Clarke already getting the snacks ready.

"Don't know why you need me, you can clearly do it yourself." Lexa said pointing to the snacks.

"Just wanted to say," Clarke said walking towards Lexa, "I really wish you didn't invite them."

"Oh well umm I know it's gonna mess up our plans for tomorrow, I- I just felt bad."

Clarke walked closer backing Lexa into the wall. She shoved her thigh between Lexa's legs and rubbing her center.

"It messed up our plans for tonight." Clarke said pushing against her center harder.

"C- Clarke." Lexa stuttered.

"Yes babe?"

"We, we uhh c- can't."

"Do you wanna go in the car?" Clarke asked smirking.

"W- what about th- them?"

Clarke took Lexa's hand and went to the steps, "Hey guys we don't have any good snacks, we're gonna go to the store down the street."

"Don't forget Oreos." Octavia yelled.

"Ooo get M&M's too." Raven yelled.

"Of course." Clarke yelled back

Clarke pulled Lexa into the garage where her car was, she got in the driver's seat while an extremely confused Lexa to in the passenger seat. She drove to the store that was only three blocks away and then parked in the dark corner of the parking lot. Clarke straddled Lexa's lap and started kissing her neck.

"Wait." Lexa said causing Clarke to look down at her, "I think...well I think I still need to finish what I started this morning."

Clarke looked at her confused as she thought, then started to smirk, "How are gonna do that?'

Lexa looked around to make sure there were no cars around, when she didn't see any she slide her hands under Clark's shirt to undo her bra. Clarke realized what Lexa was doing and took her bra off while keeping her shirt on. Lexa could see the blonde's nipples poking through the white t-shirt and licked her lips without thinking, causing Clarke to laugh.

"You wanna suck them, don't you?" Clarke asked smirking.

Lexa's cheeks flushed even more. She felt the seat start to move down until it was completely flat and Clarke was on top of her.

Clarke kissed Lexa, then moved up until her covered breasts were hovering over the brunette's face. She pulled her shirt up, "Go ahead."

"I- I- what if-" Lexa stuttered.

"It's almost one-thirty in the morning Lexa, no one's out, we won't get caught."

()

Clarke gave Lexa one last kiss before sitting back in the driver's seat.

"Clarke."

Clarke looked over at Lexa while she put her hair in a ponytail.

"Well umm, that, that was my first time doing that?"

"You mean car sex?"

Lexa shyly nodded her head.

"Oh okay, I, I feel like I should have asked first then. A- are you okay? Umm was that like too much? I- I- are yo-"

"It's fine," Lexa laughed as she interpreted the blonde, "I was just letting you know, it felt like something that you should know. Yes, I'm okay, and no it was not too much."

"Are you sure you're okay?"

"I'm perfectly fine, better than fine. Clarke, before I met you I honestly hated sex, but now, I don't know, I actually like it, like a lot."

A smirk slowly spread across Clarke's face, "Is it because I'm the only one who knows how to make you cum?"

"I hate you." Lexa said rolling her eyes as she slapped Clarke's shoulder.

"I know you don't." Clarke said as she pulled her in for a kiss, "But we better go or they'll know something's up."

After they bought the snacks they went home. When Raven asked what took so long Clarke made up a lie about needing to go to a different store, which Raven fell for. The four girls watched some Netflix then went to bed.
