Title: Unforgivable

Author: Gilmoregirl7878

A/N: I got this idea while listening to Rihanna's Unfaithful and I was watching Tristan and Isoldel. I thought of this within seconds. I know I probably shouldn't write ANOTHER story, but I am.

"Rory, you ready yet?" Collin asked coming into the room that they had shared for the past ten months.

"In a minute, Col. I'm almost finished." Rory answered while trying to latch her necklace behind her. Collin came up behind her and latched it for her. He locked eyes with her through the mirror and kissed her neck.

"You're beautiful." He murmured. Rory smiled and grabbed his hand before dragging him out the door and grabbing their coats and leaving the apartment. "We're going to be late to Finn's party." Rory scolded playfully.

"I don't care, let's go back inside. Finn would understand." Collin pleaded while Rory dragged him down a floor of stairs to Finn's dorm, where the party is being held.

"Collin, stop it. It's Finn's birthday!" Rory opened Finn's door and stepped into a room packed full of people.

Collin grabbed two drinks off the bar for himself and one for Rory and greeted Logan who had walked over to them.

"Hey, Ace." Logan smirked at Rory.

"Hi, Logan."

"Having fun?"

"Oh yeah...all two seconds that I've been here." She teased.

"Where is the birthday boy?" Collin asked, rolling his eyes at the antics of his best friend and girlfriend.

"He's around here somewhere, probably corrupting some sweet, innocent redhead just like you corrupted our sweet, innocent Ace." Logan joked.

"No sweet or innocent girl would look at you or Finn twice. Which is why I got Rory." Collin stated seriously, smirking at Logan.

"Too true." Logan agreed while grabbing a drink from the bar and starting to walk away. "I'll see you two kids later, oh and Finn wanted you to find him as soon as you got here." He called over his shoulder.

"Come on, babe. Let's go find Finn." Collin said while leading Rory further into the party towards the loudest corner, where Finn was sure to be.

"MATE!" Finn yelled drunkenly, hurrying over and hugging Collin then picking up Rory and spinning her around in a hug. "You made it!" He said happily.

"Of course we came, Finn! It's your birthday!" Colin insisted, smiling at his best friend.

"Mate, if I had a girl like that I wouldn't leave my bedroom for a million redheads." Finn joked, staring intensely at Rory until she looked away.

"She had to push me out of the room before we came here. I don't care how much I love you Finn, you don't look like that in a dress." Collin continued unaware of what was transpiring between his best friend and girlfriend.

"I don't blame you, Mate. Well, drink and be merry! For tomorrow, we will all be in a great deal of pain." Finn announced before winking at Rory and walking off into the crowd.

"Finn's quite an original." Rory stated, smiling after him.

"He's one of my best friends for a reason, but you, my dear, look amazing." Collin said while studying the black mini dress that she was wearing.

"I'm glad you think so." She responded. Collin smiled at her and wrapped his arms around her petite waist.

"Really?" He teased.

"Really." She said softly. He kissed her softly, but their moment was interrupted when a drunken guy knocked into the back of them.

Collin smiled sadly at her when they broke apart and told her he was going to find Logan. She nodded and went off to find Stephanie.

She found Stephanie at the bar, as per usual.

"Hey Steph." Rory greeted while plopping down into the seat next to her.

"Hey Girlie. Having fun?" Stephanie responded.

"I was." She said while looking wistfully at the guy across the room.

"And how is Lover Boy?"

"He's great. We're great." Rory replied, gulping down the rest of her drink.

"What's wrong?" Stephanie asked knowingly.

"Nothing's wrong!" She insisted.

"Yes, there is. You just finished half your drink in one drink. What is going on with you lately?"

"Steph, I wish I could tell you, I really do. I just have some stuff going on right now, okay? It'll be fine, don't worry." Rory pleaded.

"Fine, but promise that when this is too much for you, you'll tell me, you promise?"

"I promise." Rory smiled and Steph held up her glass, they clinked glasses and took a sip.

"Hey, Steph, I'm gonna go find Collin and head home. I'm not feeling too well."

"What? No!"

"Yeah. I'm sorry. See you tomorrow." Rory finished her drink and went to find Collin. She found him and he kissed her lightly when she reached him.

"Having a good time?" He asked.

"I was, but I'm not feeling too good, I'm gonna say goodbye to Finn and head back."

"I'll come with you," Collin told her.

"No, stay here and spend some time with your friends. I'll be fine after some sleep," Rory insisted.

"You sure?"

"I'm positive. I'll see you in a little while." She kissed him and searched through the party to find Finn. She found him and gave him a hug.

"I'm going back to the dorm, Finn. I don't feel to well," She told him.

"Ah, Love. Leaving so soon? The night is still young," Finn told her, smirking knowingly.

"Well, you know I'm not much of a party girl."

"Yeah, you like quiet, comfy places, right?" He said softly, staring at her.

"Goodnight, Finn." She responded, walking out of the dorm and headed back toward her's and Collins'.

Rory took off her shoes and walked into the bedroom, she felt a pair of arms wrap around her waist.

"You came." She stated.

"Were there any doubts?" He whispered huskily into her ear.

"Never." She breathed before his lips captured hers. He lead her backwards toward the bed and laid her down gently covering her body with his.

His kisses trailed down her neck and down to right above the dress started. His hands trailed up her thighs to her back and slowly pulled down the zipper of her dress and pulled the dress off her body.

He groaned when he saw that wasn't wearing any panties.

"I thought you would appreciate that." She whispered between her already heavy breathing. Her hands quickly unbuttoned his shirt and slid it off his shoulders, raking her nails down his toned chest, her lips finding his own desperate for the release that they gave each other.

They worked together to rid each other of the rest of their clothes and he looked into her eyes before entering her.

It was never slow. It was never fast. It was the greatest thing Rory had ever experienced, it was like that every time they were together. She closed her eyes and prayed to God that this feeling would never end.

She dug her nails into his shoulders and screamed out her release, taking him with her. They laid there together until they could see straight again and he got up while watched as he got dressed quickly.

He turned to look at her while she sat on the bed holding the sheet up against her body and opened the door to leave, but stopped when she called his name.

"Happy birthday." She told him, smiling. He smirked back to her and winked before shutting the door behind him.

Rory got dressed into her pajamas and laid back down on the bed that she and her boyfriend Collin had shared for the past ten months to fall asleep.

The bed that she had just had sex with his best friend in.
