Another entry for prompt party. Prompt 6: Regina is the (little) sister of Robin's over-protective best friend.

Robin was distracted and it wasn't good. He was in the library with his friends and they were supposed to be studying for finals, not that most of them were studying anyway, unless playing flip the bottle was classed as revision. He wasn't even concentrating on that though. He was concentrating on something else entirely. Why was she doing this to him? He knew she was doing it on purpose, knew exactly what she was up to and when he next had the time, he was definitely going to be punishing her for it.

She knew the rules and so did he, there was no way they could break them without Robin having his arse severely kicked. No one could find out about them; she was off limits and that was all there was to it. She was stood at the bookshelf directly opposite where he was sitting and kept bending over to look at books, wriggling her ass in his face.

He sat there for a couple of minutes longer before she glanced over her shoulder and met his eye, a sultry expression playing on her features, that really did it and he couldn't take it anymore. Clearing his throat, he shook his head before pushing his chair away from the table and standing up, "does anyone want anything? I thought I might pop to the shop. Snacks?"

"Yeah I'll have some jolly ranchers if you're buying," Will grinned.

"Jolly ranchers got it. John? Graham?"

"I'll take a soda."

"Salt and vinegar chips," Graham added to the list, glancing up at him from his textbook, "how come you're going to the shop? I thought we were going to be making sure we did revision this afternoon."

"Yeah well, I need to stretch my legs and grab some food, so…"

"We've literally been here half an hour."

"I know, just… never mind, I'll bring everyone what they want back. See you in a few." He grabbed his jacket off the back of his chair and glanced back to the bookcase where she had been stood. She wasn't there anymore the minx, she knew what she had done and now she'd gone and disappeared. With an almost animalistic growl, he began weaving in and out of the shelves in order to get to the exit.

He certainly hadn't been expecting his arm to be grabbed and his whole body to be shoved up against one of the bookshelves as a warm body pressed into his own. "Excuse me, I was wondering if you might be able to help me find something?" she breathed.

He looked down at her, noticing the mischievous twinkle in her eyes. It was alright for her, she was a first year, she didn't have to worry about final exams and dissertations. She was a distraction, a very, very hot one, but a distraction none the less. What was worse was the fact that she knew it, she knew just how capable she was when it came to seducing him or distracting him from what he was supposed to be doing. "Well, maybe you should ask the librarian."

"Oh, trust me, I don't think the librarian would be able to help me find what I need to. You see, it's a little personal and I wouldn't trust just anyone with that kind of information."

"Regina," he groaned, shaking his head as his hands went to her waist before running down to her hips, "as much as I would love to play your little game right now. I'm trying to revise."

"You're way too tense to revise," she whispered, her voice husky as she watched him, allowing her hands to map out his chest, though she was fully familiar with it already. "You need to relax a little, loosen up."

"Regina, we can't do this here," he warned her half-heartedly if he thought he could get away with it, he would be forgetting about revising altogether and bunking off with Regina, but he knew that his friends would be suspicious as to why he hadn't returned. "I'm on my way to the shop to get snacks."

"Robin, I haven't seen you in days."

"You were literally at mine yesterday."

"Yeah, hiding in your room," she sulked, folding her arms over her chest as she cast him a poignant look, "I'm sick and tired of sneaking around. It was fun to begin with when we were casual, but now I can't stand it. I don't want to be your dirty little secret."

"Regina, you know it isn't that easy, if it was everyone would know about it. If you weren't who you are we could tell all our friends right now."

"Please don't play that card. Robin, we've been seeing each other for an entire year. I know it wasn't meant to be a serious relationship when we started out, but it is now, isn't it? I want to be with you Robin and I don't want to have to worry about people seeing the two of us together."

"But your…"

"God, fuck Graham!" she spat with a shake of the head, "I don't care what he says about us."

"He's your brother Regina it…"

"Robin please," she took his hands in hers, "please, I don't want to sneak around anymore. I want to be able to come over to the apartment and chill out on the couch, but I can't do that because you live with my brother and he'd be suspicious."

Robin took a deep breath as he looked at her, she had a point. He wanted to be exclusive with her too and wouldn't be annoyed if people found out about them. It was just Graham he was worried about; he was scared about what his best friend might think about him having a relationship with his sister. He knew how protective Graham was of Regina, but maybe it was worth the risk, no, screw the maybe, they were worth the risk.

"Robin, if we can't tell everyone about us, I don't know how much longer we can be together," Regina whispered, looking down to the ground and he could see tears welling in her eyes. "I love you, but I can't do this anymore. I hate feeling as though I'm not worth it."

"God, of course, you're worth it! We can tell people about us. Today if you want, I won't lose you," he cupped her cheek, wiping away the tear that ran down it. "Baby, don't cry, please," leaning in he pressed his lips to hers gently, "we'll tell everyone, I love you and you're right, I want everyone to know."

"Are you serious?" she asked, smiling up at him, "really?"

"Yeah really," he chuckled, nudging his nose against hers, "in fact, come on!" he grabbed her hand and pulled her through the library, heading back to the chairs were his friends were sat.

"Robin…"

"Come on," he chuckled, tugging her with him, "hey guys."

Robin's three friends who had been sat at the table all looked up at them and Will was the first to speak, "bout time, where are those snacks at then, I… shit."

"I… we have something we need to tell you," Robin stated nervously, his hand tightening around Regina's hand. His eyes met Graham's as the other man looked from one to the other.

"What's going on here?" he asked.

"I'm kinda in love with your sister."

"What?"

"Regina and I are together and I'm in love with her," Robin quipped.

"Regina?"

"He's telling the truth and I love him too," she nodded confidently.

"Well, I'm glad that the two of you can stop sneaking around now because I'm sick of hearing you messing around in the middle of the night. Do you know how thin the walls actually are?"

"What are you saying?" Regina question, her eyes widened as she stared at her brother.

"I'm saying, you idiots, that I have known about the two of you for a while and I'm just glad you are serious about my sister otherwise I would have had to kick your sorry ass into next week."

"You knew?! This whole time we could have been honest because you already knew?"

"Yep," Graham grinned, leaning back in his chair with a smug smile.

"Oh my god," Robin breathed, relief flooding through his veins. He couldn't believe what was going on.

"Well I'm happy for the two of you, but Regina, you need to leave so Robin can study for finals."

"What if I wanted to sit here with you?" she scoffed.

"No, now get out of here and I suppose we'll see you at the apartment tonight?"

"Fine," Regina huffed with an eye-roll before pressing her lips to Robin's for a moment, "I'll see you tonight, thank you for this."

"Okay, so I might have been cool with this, but I'm not ready to see that yet," Graham shook his head. Regina walked off laughing whilst Robin returned to his chair with a cheesy smile on his face.

"Mate! The jolly ranchers, are you gonna go get them or not?"

"You know what, I'll go buy you all the jolly ranchers you want right now," he chuckled, standing back up again and hurrying to catch up with Regina, glad that there was a massive burden lifted off his chest. He could finally be with the woman he loved without losing his best friend and he couldn't have been happier.
