Author's Note: Trigger warning for discussion of self-harm.

"I don't wanna go," Kara sighed, as they boarded the jet.

"It's nice here, huh?" Lena asked with a smile.

"Yeah, definitely."

"We'll come back, if you want."

"I feel out of place here… There's just so much money. But I love the vibe. It's so relaxing."

"You know what else is relaxing?" Lena asked, voice sultry and low, making Kara arch a curious eyebrow.

"Go on," the girl offered.

"Joining the Mile High Club."

"Huh?" Kara asked dumbly as they sat down in their seats.

"You'll see."

Tilting her head in confusion, Kara buckled her seatbelt and watched as Lena stared smirking out the window.

The jet took off as soon as they were settled, with the blonde gripping her girlfriend's hand tightly, until her knuckles were white. She definitely didn't like takeoff or landing. It was far from comfortable. But knowing Lena was there with her mostly calmed her nerves.

Shortly, they reached altitude, and as soon as this happened, Lena unbuckled and rose from her seat. Kara looked even more confused than before as Lena whispered something to her butler, who disappeared behind a curtain that the brunette drew closed behind him.

"These chairs recline, you know," Lena purred, sliding her fingertips down her partner's arm without sitting down.

"Um… Are we going back to sleep or…"

"No, dear," the star chuckled, shaking her head slightly. "You're gonna fuck me."

"Wait, is that the Mile High Club?!" Kara gaped.

Lena nodded with a smirk and straddled Kara's hips as she reclined the seat for her.

"Do you want to?"

Swallowing hard, the blonde nodded, saying, "Please."

"Good girl," Lena said with a wink, kissing the girl's lips before dismounting and wiggling out of her skirt and panties.

"Lena…"

"Shh," the brunette whispered. "It's okay. The crew knows not to disturb us. We're okay. Just relax…"

When Lena slid her hands down Kara's sides before lifting her shirt up over her head, Kara did the same for her partner, unclasping the bar and letting it drop to the floor of the jet. As soon as the blonde's bottoms were off, Lena straddled her lap again and cupped her face in her hands, kissing her hard. Their tongues danced together until they were both panting, and as Kara's hands brushed over Lena's breasts, the girl moaned softly, her head tilting back slightly.

"Kara," she breathed.

"Can I…" Kara tried to ask, but found herself trailing off as her cheeks became warm.

"Please," Lena whispered back, kissing her again. "You don't need to be nervous."

"I've… I've never—"

"Wait, what?"

"Yeah, um… I…"

"Oh, my God, Kara! Why didn't you tell me?"

"It didn't matter."

"I'm so sorry. I wanted to be—"

"It was perfect," Kara told her softly, sincerity in her voice. "Now… Relax."

Biting her lip, Lena received the command with a nod. Then, Lena gasped as Kara reached down and slid her fingers through her already-soaking folds.

"So wet already," the blonde cooed. "So ready for me. You've been waiting for this, haven't you?"

"For so long."

"Good," the younger girl announced, dipping her fingers in Lena's core, slowly, with one smooth, careful movement.

The next gasp that Lena let out in response to the fullness of her sex was louder than the first, and despite wanting to keep her composure, she her hips rocked forward involuntarily against Kara's hand.

"That's it, honey," Kara urged her. "Keep going."

"Harder," Lena panted, feeling her lover's fingers curl for the first time.

The way Kara stroked her made Lena surprised that she was inexperienced in this area. Her movements were gentle bit firm and touching the exactly perfect places.

"Harder," the brunette repeated, when Kara only increased the pressure a small amount.

"I don't wanna hurt you," Kara protested. "I—"

"Fuck me, Kara," Lena begged. "Please, fuck me. Do it hard. Wreck me."

At these words, the younger girl felt her mouth water. The begging, the moaning, the little gasps Lena was making… it was all too much, and even Kara was getting wet from the sounds. So, urged on by her partner's desperate, dirty pleas, she began to pound her fingers into Lena's core, curling them hard several times before pulling out and pushing in again.

"Good girl," Kara praised Lena, when the girl let out several loud moans of pleasure and continued to rock frantically against her.

It was funny to her that she'd turned the 'good girl' tables on her partner. Now Lena was feeling the rush of arousal brought on by these words and feeling just how incredibly hot they were. It made Kara feel amazing to know how well she was pleasing her girl.

The harder Kara moved, the more Lena begged.

"Please. Please. Harder!" Lena cried, almost screaming.

Briefly, Kara wondered how her butler was feeling, likely hearing all this, but the thought faded from her head almost instantly. Lena's moans eventually turned into screams as her thighs started to quake as they clenched around Kara's hips. It was an awkward angle to be fingering her, but Kara was determined not to stop, no matter how badly her hand was cramping. Luckily for her, it didn't last much longer.

Letting out a long scream that almost sounded like agony, Lena came hard, clenching around Kara's fingers as the girl continued to move, over and over again, hard and fast, drawing out the star's orgasm.

"That was…" Lena started breathlessly, once her heart rate had slowed enough for her to speak again. "That was the best I've ever had."

Kara blushed and grinned triumphantly, having been worried about her performance previously but feeling comforted by Lena's words of praise.

"Good. Do you want another?" Kara cooed, sliding her hands over Lena's thighs, which were still vibrating from the absolutely electric force of her climax.

Lena nodded immediately, grabbing Kara's hand and pushing it back against her opening. Then, before Kara could move again, she shook her head.

"Yes? No?" Kara asked, confused.

Again, Lena shook her head and said, "I… I need a break. That… That was really intense."

Smirking, Kara leaned in and kissed her lover's cheek before pulling her close and hugging her gently, rubbing her back the way Lena had one for her the night before.

But when she felt how stiff Lena's muscles were, she pulled away, looking concerned, and gazed into the celebrity's eyes, which were filled with tears.

"Lena? What's wrong?"

"I'm embarrassed."

"Why, honey? What just happened?"

"I… I don't like when you touch my thighs."

"I'm… I'm sorry, Lena. I didn't know. Is… Is there a reason?"

Closing her eyes to avoid looking at her partner, Lena confessed, "My cuts."

"Oh, baby girl. You're beautiful. All of you is beautiful."

"No."

"Yes. Now, let me hold you."

Sighing, Lena shook her head and started to dismount Kara's lap, but the girl held her gently, keeping her still.

"Don't run away from me. From this."

This caused Lena to connect their gazes again as tears rolled down her tinted cheeks.

"I don't want you to be ashamed of anything, especially not your body. But… Lena…"

"Yeah?"

"Please, honey… Promise me you'll stop. I'll do anything to support you, and if you ever need anything, you can tell me. Don't do this alone. Don't suffer alone. I'm here. You don't ned to hurt yourself."

Inside, Lena realized that this was too much for Kara to ask, but she also knew her girlfriend, as caring as she was, wouldn't be satisfied with anything less than a genuine promise.

"Pinkies don't swear," Lena said softly, feeling a pit forming in her stomach as she held out her middle finger.

Kara chuckled at the 'pinkies don't swear' comment and used her own middle finger to hook into Lena's, solidifying the promise.

"I'll call you," Lena told her. "I just… can't promise I won't be a mess. I'm always a mess."

"I love all of you," Kara vowed. "Especially the messy parts."

This earned a smile from Lena who kissed her partner's lips and hugged her again.

Eventually, Lena fully came down from her high and crawled off of Kara's lap, feeling comforted by their conversation. The two got dressed again, reluctantly separating to do so, and prepared for landing.
