Prompt: "This is definitely what you think it is."
"Remember what I told you," Alex said as she straightened her sister's collar. "Sloooooowly, Kara."
"I'm so scared," the younger girl replied. "I don't want to break this guy's nose too, Alex."
"And you won't if you just do what I say, ok? You'd never hurt me. Pretend he's me."
The krytonian teenager nodded. "I just... I'm not sure what to do. I mean... do I use tongue straight away or... or... do I wait for him to do it?"
Brown eyes rolled. "You're waaaaay overthinking this. Just do what feels natural. There's no handbook for kissing, Kara. You have to just find a rhythm that suits you both."
"Alex, can you teach me? Like... can you show me?"
"Uh..." Alex swallowed. "I'm not sure that's a good idea. Sisters aren't supposed to do stuff like that."
But Kara looked so dejected that the older girl sighed and went to their bedroom door to close it. Then she sat on the bed next to her adoptive sister and took her hand. "Ok, I can show you how to do it but... keep it to yourself, ok?"
"Ok," Kara agreed. "Thanks, Alex. I really appreciate this."
"Ok, so let's start with loosening up. I can see how tight you are from here. Roll your shoulders and your neck, take some deep breaths and relax." Alex waited as Kara did as she was told. "Good, better." She took a deep breath herself. "Ok, now just close your eyes."
Kara resettled herself and her baby blues disappeared behind fluttering eyelids. Her senses registered Alex moving closer and then a warm palm settled against her cheek. "Just relax," Alex whispered as her thumb ghosted across the younger girl's lips. Then the thumb went away, and Kara gasped as a pair of soft lips brushed hers. "It's ok," Alex added. Then kissed Kara again, this time with firmer pressure. It lasted only a few seconds and then she was tilting her head, changing the angle. Kara's hand came up and hovered in the air as she kissed her sister back, but she gasped again as Alex's tongue barely brushed her lips and then moaned instinctually as the tongue barely sipped into her mouth. Her hand suddenly knew what it wanted to do, and it tangled into her adoptive sister's hair to pull her closer.
Alex moaned this time and the kiss deepened. The older girl's hand was on Kara's chest now, caressing gently and her skin went from tingling to burning.
"WHAT THE HELL IS HAPPENING HERE?!"
Alex's mouth disappeared with an audible pop and Kara, slightly dazed, had to take a deep breath before she could register what had happened.
"Mom!" the older girl exclaimed. "This is totally not what you think it is!"
Eliza's face was pale, and her eyes were conflicted. Kara saw the potential for explosive anger, and she came to her sister's aid. "No, it's definitely what you think it is! There's a guy I want to kiss at school and Alex was teaching me how to do it because the last guy I tried to kiss, I broke his nose with my indestructible face!"
Eliza blinked but her shoulders sagged and after a moment, she nodded. "Ok, alright." She cleared her throat. "You're lucky to have her to help you, Kara."
The kryptonian smiled. "Oh, I know, Eliza. She's the best sister on Earth."
The eldest Danvers turned and left the room. "Get your homework done, Girls."
"Sure, Mom!" Alex called after her, then turned to make sure Kara was ok... only to be met with soft lips as Kara pulled her close and kissed her again.
"We're not sisters by blood," the kryptonian whispered then.
"I... we can't," Alex said, shaking her head as she put a finger against Kara's lips. "It's not... we shouldn't."
And then she escaped the room, leaving a dejected younger sister behind, even more confused than she was before.
