A/N: By the by, when I started writing and planning this, Prom was a long way away. So I'll be writing a prom chapter later that's completely different than the episode, just a heads up. And this chapter is slightly sort of kind of bordering on M, so...be warned. It's not smut or anything close to that...because I suck at writing that stuff.

Santana rapped on the door thrice, and Finn pulled it open. His regular goofy smile was panted on his face. Santana hadn't realized how much she'd missed it until now. But his smile turned into a frown when he saw that it wasn't Rachel.

"Santana?" Finn asked. Santana smirked and cocked her head to the side, brushing past him and coming into the house without invitation. Finn closed the door and waited for her explanation.

"What's up Finnocence?" she asked all too innocently. Finn looked at her skeptically.

"Shouldn't I be asking you that?" he asked. Santana walked over to him and dragged her fingertips across his chest. He shuddered.

"What do you want?" He continued. Santana cocked her head again, staring up at him.

"What do I want, Finnocence? I want you," she grinned impishly. Finn gaped at her.

"But...I...you...we. I-I'm dating Rachel," Finn finally formed a coherent sentence, much to Santana's surprise. Santana smirked, placing her hand flat on his chest.

"Yeah, and you were dating Quinn the first time we became fuck buddies," Santana licked her lips. Finn backed away, shaking his head. Santana quirked an eyebrow. He should've known better than to resist. Santana always got what she wanted.

"But I love Rachel," Finn pressed. Santana rested her hand on her hip.

"Do you? Then why didn't you cheat on Quinn with her? Face it Finn, you want me. I can see that you want me," Santana teased him. Finn blushed and tried to block himself from her view.

"Santana, please don't do this," Finn begged. Santana bit her lip.

"Finn, be my Bad Boy again. Let me be your Gorgeous Nightmare," Santana murmured. Finn shook his head defiantly, trying to convince himself that she was wrong. It was cute, really, how hard he was trying to stop her.

"Santana, please, stop" Finn pleaded. Santana decided to play her final card, the below-the-belt hit. She ran a hand through her glossy hair and sighed.

"Fine. I guess I'll just go find Sam and give him one last round of fun," Santana said and started to leave. Her fingers had just grazed the doorknob when Finn's hand landed on her wrist and her twirled her around to face him. His face was dangerously close to hers. His free hand crept around to grip her waist. Santana smirked slightly.

"Sam will not touch you again," Finn breathed, his eyes burning with jealousy. Santana was so close to satisfaction.

"I won't be abstinent for you. Fuck me or I will go to Sam," Santana gave him his ultimatum. Finn's face twisted with longing and with desperation. He was very clearly torn.

"I want you back Finn. I want my Bad Boy," Santana whispered. Finn looked up at her, and the only thing in his eyes was want. Santana smirked. She'd won. Finn crushed his lips to hers, pressing the back of her head against the wall and also placing his other hand on her waist. Santana kissed him back hungrily.

Two weeks without Finn was too long. And Santana felt so happy to be his 'mistress' once more. She wrapped her legs around his waist and he carried her upstairs. She'd forgotten that he was so good at sex since being with her.

Santana was panting slightly when they were done. She looked up at Finn. She rolled over so her head was on his abs - which, by the way, he did have- and smiled.

"That...was incredible," she said, trying to catch her breath. Finn bent over and kissed her shoulder.

"That was fucking amazing," he agreed. Santana was starving. She looked up at Finn pleadingly.

"I'm hungry. Make me some eggs?" she asked. Finn rolled his eyes and climbed out of bed. He looked at her, sprawled out on his bed in nothing but her underwear and tank top. She watched him take her in.

"How can I say no?" Finn sighed, holding out his hand to her. Santana took it and he gave her his shirt. She slipped it on over her head and they walked downstairs. Finn made her scrambled eggs and they sat at his counter in silence as they ate. Santana used to hate silence, but she didn't mind silence with Finn. Suddenly, there was a sharp gasp. Finn and Santana whirled around.

"You're...basically naked...in my step-brother's shirt...and it's late at night...you both have bed head and smell like...Finn's bed," Kurt gasped. Finn leapt to his feet.

"Kurt it's not what it looks like!" Finn insisted. Kurt quirked an eyebrow.

"You're fucking Santana behind Berry's back," Kurt said. Finn cast a look at Santana. She shrugged indifferently.

"Okay, maybe it is what it looks like," Finn nodded. Santana rolled her eyes, and decided to take control of the situation.

"Kurt, I know we haven't always been on best terms, but please don't tell the hobbit. I'd like to keep my fuck buddy," Santana said. Kurt looked at his step-brother, then to Santana and back at Finn once more.

"Fine. I won't talk. But only because I want to pretend I never saw this and also because I hate the dwarf more than I hate Satan," Kurt said. Finn's jaw tensed.

"Don't call her that!" Finn yelled. Santana frowned, thinking he was defending Rachel.

"Wow, you two are in deep if Finn's defending you," Kurt shook his head and left. Santana gaped at Finn. He turned and walked over to her, kissing the nape of her neck tenderly, sending tremors down her spine. He placed his hands on her smooth thighs.

"It would suck if you're mom walked in," Santana whispered against his head. Finn continued sucking at the skin of her neck.

Santana walked into glee club the next day, proudly showing the bruise that Finn had raised the night prior. None of them might not know who gave it to her, but Finn knew. And his face lit up when he saw it.

He had marked his territory.

And she enjoyed it.
