A/N : Btw, I purposely spelt hormones wrong. For some odd reason, FanFiction is not allowing me to post this chapter as a whole so I'm breaking it down into sections.
The rest of their drive was relatively quiet. About 20 minutes later, Derek was approaching their driveway.
"I guess this is where we part. Meredith, I'd love to see you again." he turned and told the older Grey. Lexie could've swore she saw a twinkle in his eye.
"Well Derek, it all depends on my sister. We don't ever do anything without one another."
Lexie felt obligated to say something.
"Oh no no no, if you guys wanna go out on a date alone I'm more than fine to-"
It was Mark who interrupted her and he was smiling.
"Nah its cool. Lexie and I could always do something without seeing you two love birds shake it up."
Meredith clapped. "Perfect! It's a double-dateish."
Derek nodded. "Mark and I are having a house party on Friday, you shoud both come!"
They all got out of the truck and walked towards the house. Turning around, Lexie came face to face with pretty much the hottest guy she's ever seen.
"A-are y-you sure? I-I mean y-you d-don't have-"
"Lexie I'm more than sure. I'll see you Friday." Mark smiled, and kissed her cheek. Although they pretty much just met she was sure she'd end up feeling some type of way for this mysterious fella.
...
The guys were on their way home when Mark broke the silence.
"They seem pretty cool, those Grey sisters. Not to mention extremely hot." he smirked.
Derek laughed. "Tell me about it! Meredith is beautiful."
"No way. Have you seen Lexie? God she's gotta be the fucking hottest one between the two. And her ass? I mean seriously Shep, have you seen that?" shaking his head in protest, he continued. "I mean yeah she's pretty and she's got an amazing body, she's perfect."
"Mark, I don't want you to see her as just another piece of meat. I think Mer is pretty amazing and I don't want your whoremones towards her sister screwing this up."
"Shep, I'm not that heartless. I'm not just gonna fuck her and not talk to her. I'm not sure if I'm even gonna fuck her but-"
Derek cut him off. "No. Little Sloan does not enter Little Grey."
Now he was confused. Did he really just...?
"What?" Mark looked at his bestfriend perplexed.
"Little Sloan does not enter Little Grey."
"That was just rude...and inaccurate. Big Sloan!" Mark stretched his arms in front of him to prove just how "big" he was.
Derek just laughed and continued driving.
