Here is finally the second part! I'll eventually update again today or tomorrow! Enjoy hehe

They made their way downstairs.

'Meredith, hi!' Mark smiled. 'Derek!' He grinned.

'No need to do that, Mark. Keep that fake smile for the drunk college girls you bring here every night.'

'What? Oh, please…you're honestly not better than me, and you know it!' Mark retorted.

'Is that a joke? Seriously, I-' Derek groaned, glancing at Mark.

'Stop!' Emily interrupted. 'We're not in high school anymore. Stop fighting over stupid things!'

'What? Is that what you think? He-' Derek started

'No! I don't want to hear your explanations. I'm tired of it. Don't you realize how extremely annoying you two are?'

'How annoying he is' Derek muttered.

'I have to listen to your constant whining, Derek. Leave Mark alone.'

'Thank you, lil' sis.'

'It wasn't a compliment. You're worse.'

Derek laughed and grinned.

'I beg to dif-'

'Mark, give us a break. You're always trying to annoy the crap outta everyone. It's boring the pants off me'

'I totally agree with that' Derek whispered.

'God, please, can we get over this already? We didn't eat and it's 9. I'm hungry' Meredith interrupted.

'Well, so am I' Emily answered. 'I hope everyone brought their swimsuits. I know a nice restaurant next to the beach where we could eat before going swimming'

Meredith glanced at Derek. He smiled 'I'm gonna win' He mouthed. 'No you're not' She answered.

Emily and mark shared a questioning look.

'What are you two up to?' Mark asked. 'Yes, what are you plotting?' Emily added.

'Nothing' Derek and Meredith answered at the same time. Meredith giggled.

'This is really weird. You two are weirdos.' Mark said, heading to the front door.

'Let's go, people' Emily said, ending the conversation and taking her purse.

'Right' Meredith answered slyly.

Derek closed the door behind her.

'Which car are we using?' Meredith asked.

'I could take you in mine' Mark suggested, smiling.

'Well, I'll take Emily then' Derek announced.

They all made their way to their cars.

Fifteen minutes later, they arrived, parking their cars in front of the crowded restaurant. The beach was empty, though. One hour later, they were all out of the place, few feet away from the ocean.

The glint of the moonlight on the sparkling water, the wind softly sweeping the sand and making the tree branches slightly move, creating shadows and small noises: the scene was breathtaking. Meredith couldn't move, astonished by what she was looking at. She just wanted to dive in, enveloping herself in the peaceful world the sea was providing her. She started walking to the edge of the sea, taking her clothes off slowly. Everything around her had disappeared. She felt like she was alone, billions of miles away from the earth. The smell of the ocean surrounded her. She put her feet in, the feeling of the water on her skin and the cold wind on her body making her shiver. And she kept walking until the water covered her thighs, her belly, her breasts. Only her head was kept out of the water. She closed her eyes. And that's when she felt it. His hands on her waist. She didn't want to move, savoring the excitement it created inside her. He got closer, and she could feel his skin against hers, realizing she wasn't the only winner. His chest was pressed against her back, and he wrapped his arms around her. Her eyes were still tightly closed, her body still hadn't moved. She felt him move, taking her wet hair away from her neck. She wasn't sure what to do. Should she move, should she talk?

'Hey, Meredith! What are ya doing in the water already?' Mark yelled. She felt his hand slip off her body and he started walking away from her. She opened her eyes, turning around. She felt empty now, missing the feeling of his skin, his warm breath on her neck. Derek was already off the water, wrapping himself in a towel.

'God, Derek, why were you naked?' Emily asked.

'Just a bet. And I won' He smiled, looking tenderly at Meredith.

'Me too' She whispered.

Meredith quickly got out of the water, running to her bag and getting her towel out as fast as she could. She wrapped it around her tiny naked body, blushing.

'This evening is definitely worth it' Mark smirked.

'Shut up Mark' Derek said.

'Oh, you two are not gonna fight again are you?' Emily sighed.

'No, it's fine' Derek answered. Meredith put her swimsuit on and let the towel fall on the sand. She looked stunning. Derek stared at her for few seconds. She blushed.

'Well, don't you guys wanna swim?' She asked, smiling.

'Of course we do!' Emily answered, standing up and getting her clothes off, revealing her pink swimsuit. Derek put his own on quickly. They all headed to the sea.

'It's really warm tonight' Meredith stated.

'Yes it is' Derek whispered.

They all went in, Mark starting to drown everyone.

'God, Mark you're so childish. My hair is all messy now!' Emily yelled. And as Mark turned around, his back facing her, she jumped on his back and made him fall into the water.

Everyone laughed.

'Not funny' Mark groaned. Meredith looked at him. He really had a perfect body.

'I have an idea' Meredith stated.

'What?' Mark asked.

'We could make a water fight. You know, the girls sit on the guys shoulders and try to make the other one fall.' Meredith smiled.

'Great idea! I'm with Derek' Emily said, smiling.

'Alright, I'm with Mark then' Meredith answered.

'Grrrreat' Mark grinned.

'You're gonna lose, man' Derek said.

'That's what you think. Meredith might look weak and tiny, but she's as strong as a rock!' He smiled. 'Yes I am' Meredith giggled.

'Oh, don't you think so, I can be pretty strong myself' Emily smiled.

'Let's start, and we'll see.' Derek said.

Meredith and Emily both climbed on Mark and Derek's backs. 'Hold me tight, Markie, you're my hero!' Meredith giggled.

'Markie? God, I like you, but don't ever call me Markie again, babe' He smiled. 'I'm completely willing to hold you tight, though' He grinned as he took her legs in his hands.

'The battle starts at 3' Derek announced, interrupting Mark and Meredith's flirting time. '1…2…3!!!' He started walking towards Meredith and Mark as the girls tried to push each other off the guys' shoulders. Meredith leaned forward, grabbing Emily's arm and trying to make her fall unsuccessfully. She giggled. 'God you didn't lie when you said you were strong!' Emily pushed Meredith backwards. Meredith lost her balance but didn't fall. She wrapped her arms around Mark's head and got back on his shoulders.

'Oh my god Derek, your swimsuit fell off!' Meredith said, faking a shocked look.

Derek looked down at himself, the movement making Emily fall.

'Yay!!!' Meredith shouted. 'We won!' She got off Mark, hugging him tight.

'We did, honey' Mark grinned, putting his hands on her lower back. Derek and Emily were furious. 'You cheated' She said.

'We did not, no one ever said it wasn't allowed to talk!' Meredith giggled.

They all made their way to their towels. Mark and Meredith sat next to each other, Derek looking at them, still angry. 'We're the best water fight team ever!' Mark said, grinning.

'Yes we are' Meredith answered. She looked at Derek. 'Derek, don't be mad, next time I'll be with you and we'll win' She smiled softly.

'I hope so' He answered.
