[sorry for taking so long]

Back in the DEO Alex Danvers stood in front of a screen. She didn't know what she was looking for exactly when she watched the sequence repeatedly. Something was eating all cats in a small neighborhood. This was the only footage of a creature that was supposedly the 'cat-eater' – a video taken by a 14 years old's cellphone. She watched the same video for the sixth time when she received a message. Aeneas sent a photo of himself, his mother and – Kara! "We are fine in case you wondered where your sister was hiding 3. Love you" said his text.
"Didn't she say she was staying in Spain for a while with Lena?" Alex thought out loud.
"Who is in Spain with Lena?" Brainy asked suddenly from behind of her.
"Oh god Brainy! What have I told you about sneaking up on people?"
"You have indeed told me, not to do so" Brainy recognized and nodded.
"Well, Kara told me she was going to stay in Spain with Lena for a couple days…but now my husband shows me she is with him in Greece…"
"Spain and Greece are geographically on the opposite ends of Europe – even for Supergirl not too near" Brainy commented.
Alex sighed and narrowed her eyebrows in thought.
"Something is off about this" she mumbled skeptically.

After Lena put her luggage in their suite they went to check out the pools and the beach. However neither of them had any bathing suits with them since neither of them planned any of this, so they didn't go inside. Instead they went back to the hotel area where a small hotel bar was almost crowded. Lena ordered a drink for herself and asked Kara what she was having. Since Kara didn't feel the effect of alcohol she ordered an ice tea. After managing to find out that melocotón was peach Kara take a look at the bar's interior furnishing. Two guys were singing off-key "Hey DJ" by CNCO at the karaoke stage. Lena followed Kara's gaze. She giggled.
"You should sing a song" she suggested. Kara turned surprised.
"What? NO- noo. I am only gonna make a fool of myself" she was sure.
"Of course you won't. I know you make a good singer" Lena disagreed. She grabbed Kara's arm. "Seriously, you have a beautiful voice- you kind of always reminded me of this girl from glee…" Lena said.
"Uh, you're not the first to say that. I mean this lookalike thing. Anyways, I wouldn't dare all alone in front of all these people" Kara admitted.
"Aha, the girl of steel, afraid of singing?"
Kara blushed and lowered her glance a little ashamed. That's when two guys approached them.
"I am sorry but I overheard that somebody's a good but shy singer" said the handsome dark-skinned British guy. He was charming which made it less weird he 'overheard' their conversation. His friend, a skinny Spanish guy with a man bun who looked like he was into indie and alternative music grinned as his side.
"We are in a band and I'd like to sing a black eyed peas song with him but we're missing a Soul" the long-haired said. He had a strong Spanish accent and he was cute. Another man approached them. He was tall and bald and didn't say a word.
"And- and you want me to sing with you?" Kara asked insecurely. Lena smiled and gently pinched Kara in the side.
"Come on as if this wasn't fate" she said.
"Do you know MAMACITA? It's a rather new song with Ozuna" the handsome said and pointed at his friend while saying Ozuna.
"This isn't Ozuna" Lena said confused.
"No of course not but he will sing his part. And you will sing the girl's part?" he suggested. Kara looked at Lena almost tormented. But Lena didn't let Kara chicken. She turned Kara around so that she faced the pretty man and answered for her: "yes she knows the song and she would love to sing it with you."
Then she gently pushed Kara with the men to the stage. The Spanish guy whispered something in the 'DJ' s ears and the song started. The crowd immediately was into it and started dancing. [if you listen to the song MAMACITA by black eyed peas it will be cooler - Soul's voice somehow reminded me of Melissa Benoist's btw]
Kara rocked it. Her voice was even more beautiful than her appearance. Lena watched her with big wide eyes and was so attracted to her Alien friend. "You got me caliente too, Kara" Lena whispered to herself. She cheered with the crowd as the four performed their song laughingly and visibly enjoying it. Kara almost beamed.

The crowd was going wild for them and begged the 'group' for encore. However they left the stage and Kara approached Lena still keeping the excited grin and the seductive eyes. She was so confident and sure. She tugged Lena to her chest and hugged her passionately.
"Thank you for making me do this" she said calmly but Lena could hear the pure honesty. This tone in your voice when what you're saying feel so right and freeing.

When it got dark, Kara grabbed Lena's arms excitedly and bit on her lower lip.
"Lena L- I can't believe I'm really going to say this- Lena Luthor, do you want to go skinny dipping?" Kara offered seductively but laughingly. Lena smirked.
"Tempting" she said "but I don't know…"
"Oh come on, where is rebellious Lena? Besides, nobody will see us. I mean we won't even see each other" Kara tried to convince her. 'That wouldn't be a problem to me' Lena thought and suppressed a smile.
"Kara-"
"No, not Kara. We're doing this" Kara decided. She was stubborn, so Lena did not see any sense in declining anymore.
"I guess you're leaving me no choice" she finally said. Kara smiled and said 'yes' while goofily stretching her fists in the air.

When it was about 00:30 AM there was nobody outside like Kara predicted. It probably wouldn't have been so empty at week-ends or while vacation but Lena and Kara weren't there at peak season. "You wanna go in the sea or the pool?" Kara asked.
"The pool, definitively. I'm too scared there will be anything in the sea" Lena answered.
"Girl, you're with Supergirl, what could happen?"
"Well, you can't see what's in the water when it's dark."
"I have x-ray vision."
"I don't know if that's how it works."
"Fine. The pool it is" Kara gave in and smiled. "It's the least you can choose if you have to get naked for me" she added. She realized too, that it had a certain sound to it but she didn't mind.
Kara began undressing, protected by the dark. Lena was still wearing her summer dress when Kara was already completely naked. Lena had to fight the urge to look at Kara's bare form so much she forgot to undress.
"Hey, take your clothes off" Kara commanded her smiling. Lena decided to join the game.
"Or what?"
Kara raised her eyebrows surprised. "Or else."
"Why don't you make me." Lena responded earnestly. Kara bit her upper lip. Then she approached her friend. The moonlight shone a little on her body which made Lena see her whole body.
"I can always make you take them off" Kara said.
"But I wouldn't like to destroy your pretty dress" she added. 'Lame excuse' Lena thought but smiled. Then she took off her clothes getting as naked as her friend.

Kara tried so much not to stare at Lena but she was fazed by her sexy figure.
"Let's swim, shall we?" she proposed. Lena's hair was tied up in a loose tight bun, while Kara's was in a loose high ponytail.

Lena dipped her toe in the water just to start back quickly.
"Oh god, Kara it's so cold."
Kara went to try herself. Then she grinned brightly.
"Not for long" she promised and used her heat vision to heat up the water. Lena smiled eagerly and Kara laughed. When they went inside, the water had the perfect temperature.
"Have you ever skinny-dipped before?" Kara asked. Lena nodded but rolled her eyes.
"Back in university I went with three guys and two girls but it didn't end well" she told Kara. Now completely in the water, Kara raised her brows.
"What happened?"
"Well, two of the guys started making out with my two friends…"
"And the third thought…"
"…yes. When I told him I wasn't interested he made his friends leave which made my friends upset with me" Lena finished her story.
"So you never got to make out in a pool" Kara guessed. She sounded so seductive. Lena shook her head.
"Not that I didn't have the opportunity- I did too many times" Lena started.
"I don't doubt that" Kara mumbled.
"I just never wanted to." Lena finished looking intensively at Kara.
"You don't doubt what?" she repeated playfully, her eyes fixating Kara.
"That there were many admirers. I bet you had all men waiting for you" Kara whispered while they approached each other slowly.
"Oh- not just men" Lena said and licked her lips.
"I don't- I don't doubt that either" Kara said clenching her fist underwater. They were only about 30 inches [76.2cm] apart from each other. Lena didn't know how many hints she had to throw at Kara until she would made clear what she wanted.
