A/N: So this story has obviously been kind of AU but here comes the start of the VERY AU prom chapters.
Santana hated prom dress shopping. It was hell. Okay, it wouldn't have been hell normally. Santana loved dress shopping because with her dad's salary, the sky was the limit and Santana looked smoking in half of the dresses. She hated this dress shopping because it was with the glee girls and their prom dates would be joining them in an hour. And it was bad enough that, even though Santana looked hotter, she'd already seen on Berry try on seven different dresses. Dresses she'd be wearing while she danced in Finn's arms.
And Santana thought that was bad. Oh no, when the guys came it was worse. Sam was bearable as he watched in awe as Quinn came out in dress after dress. Artie was also tolerable as he went gaga over Brittany's dresses. Mike was quiet, so Santana could stand him. And Santana got a kind of sick amusement of watching Puck and Lauren do their prom thing. Blaine and Kurt were cute, and Mercedes was going with some Warbler who was nice, so Santana could deal with those people. It was Finn that hurt.
It hurt because while Santana tried on gorgeous dress after gorgeous dress, Finn was staring at the less beautiful Rachel. He told Rachel she looked pretty, that he loved her...that no girl could compare to her. It made Santana want to tear Berry's head off. So, in her anger, she tried on a formfitting, strapless red dress. She fluffed her hair once in the mirror before stepping out to show Kurt and Blaine, the only two people out off the whole group to help her with dresses.
"Oh my god, Santana," Kurt breathed in awe. All fourteen New Directions kids (thirteen if you counted Blaine) got silent as they all stared at her. Santana saw exactly the kind of satisfaction she was looking for. Rachel's eyes filled in inferior envy and she excused herself, cursing all the now 'ugly' dresses. Santana caught Finn's eye. He couldn't keep his gaze off of her. The other kids migrated to the other side of the store. Finn stayed to 'wait for Rachel'. As soon as they were gone, Finn pulled Santana into the dressing room.
"This is a lady's dressing room," Santana teased him. He didn't smirk. Apparently he wasn't in a playful mood. He pressed her against the mirror and kissed her slowly, making her shudder.
"Do you have to look so goddamn beautiful when Rachel's around?" Finn asked. Santana pulled away from Finn for a moment.
"Keep it in your pants Finn," she said. If he got caught, their fun and games would have to stop. Finn pouted and nuzzled her neck.
"But I want you," he whined. Santana used all of her will power not to cave.
"But Rachel will be back any minute," Santana murmured. Finn sighed and pulled away from her. He slipped out of the dressing room unseen. Santana sighed and fell back against the mirror, running a hand through her hair.
She'd come so close to succumbing to her want for him.
She knew that their relationship was changing. She was starting to feel for him and starting to show emotions around him. He was acting sweet around her. Santana repeatedly told herself that only reason she wasn't stopping their fling was because the sex was too good.
Santana bought a dress -a different dress, mind you- and left with Kurt, Blaine Quinn and Sam. Sam and Quinn being back together was like heaven to Santana. Quinn was nice again, Sam didn't think that he was in love with Santana and that made Santana happy. Blaine dropped Quinn and Sam off at Quinn's house and then dropped Santana at her house.
"He does care about you," Blaine told her before pulling away.
When Finn came over later that night, he brought some Chinese takeout with him. Santana had always had an infatuation with Chinese food and so eating came before sex for once.
"So, did Berry pick out a dress?" Santana asked. Finn nodded, slurping his noodles.
"Yup. But she won't let me see it. She insists the same superstitions apply to prom as they do to marriage," Finn rolled his eyes. Santana laughed.
"She's psychotic. I wonder why you chose to date her," Santana snickered. Finn set down his chopsticks slowly.
"Well, I love her," he shrugged. Santana's laughter stopped. They'd reached a very, very sore subject. There was nothing Santana hated to talk about more than Finn's feelings about Rachel.
"If you love her so much, why are you here?" Santana asked him softly. Finn set his lo mein aside. He cupped Santana's face.
"Because you are my gorgeous nightmare. You're tempting, infatuating and completely addicting. I miss you when I'm away from you," Finn told her. Santana nodded and lifted her chin so that her lips were pressed against his. Finn moved Santana's cardboard box of chicken and Chinese vegetables before laying her down.
Santana looked up at him, his words resounding in her head.
I miss you when I'm away from you
"I miss you too," she murmured so low that he couldn't hear.
