"HEY!" Blaine exclaimed as he opened the door and hugged Rachel and Sam in turn, inviting them into the Hudson-Hummel home.

"Where's Kurt?" Rachel asked.

"He went to Mercedes' parent's house early this morning to get ready before I came here." Blaine explained.

"Nervous?" Sam asked. Blaine laughed but also nodded.

"How about you, best man? Nervous about your speech?" Blaine asked.

"Nah, I've got it covered." Sam smiled. He looked at Rachel, who looked back briefly then turned away. Blaine picked up on the tension.

"Well I'm gonna sort out my make-up after my disaster trying to do it on the train, so...yeah..." Rachel drifted off into the next room, which quickly filled with loud laughter and cheering as most of the girls gathered together. Sam watched her go.

"...What's up with you two? You were fine when we left a few days ago." Blaine asked.

"It's, uh...complicated. I'll tell you later." Sam said.

The service went swimmingly well; people laughed, people cried and people cheered. Kurt and Blaine gave emotionally charged vows filled with love and sealed with a kiss as they were finally married. Throughout the service Sam and Rachel kept glancing at each other, but continued to avoid contact as much as they could. Rachel still felt huge guilt over their conversation on the train.

After the wedding came the reception dinner, where Sam's best man speech was very well received and filled the room with laughter and sadness as he made many heartfelt statements about his relationship with Blaine. After many people cried over Kurt and Blaine's speech that they dedicated to Finn, Rachel found herself thinking about her first love and feeling so guilty when she looked over at Sam. However, when she looked at Sam she felt feelings that she hadn't felt since she every time she looked at Finn.

He'd want me to move on, and he knew and trusted Sam. He's a good guy and being with him felt good. It felt right.

Even with that thought, Rachel's head was filled with doubt.

That evening the music of the disco could be heard all around and the dance floor was constantly packed, whether it was with Kurt and Blaine sharing their first dance to a mash-up of 'Teenage Dream' and 'Blackbird' or when a really popular dance hit was played. Sam sat in the corner with a drink as Rachel was talking to Quinn at the opposite end of the room, occasionally looking at him also. Sam grew tired of feeling guilty and rejected when he looked at her so stood up and went outside to get some fresh air. Blaine watched him go and followed him after whispering 'I love you' to Kurt and kissing him passionately.

Sam was sat on a brick wall outside of the hall where the reception was held, staring in front of him. Blaine sat next to him.

"Your speech was awesome." Blaine said. Sam smiled.

"Thanks. Had a good day?" Sam asked.

"Best day of my life," Blaine said with meaning, "And I have an amazing best man to thank for most of it, which is why I need to make sure that you're okay. Normally it's hard to get you off of the dance floor."

"...I don't feel like it." Sam said.

"Is it about Rachel? You two have been really close lately and all of a sudden you're not speaking." Blaine said.

"That's the problem; we got really close this morning." Sam admitted.

"...Huh?"

"Rachel and I, we...we did it." Sam said awkwardly. Blaine looked at him, confused.

"We did it."

Blaine gasped and covered his mouth in shock.

"NO WAY?" Blaine exclaimed and Sam nodded.

"Tell me everything; you're secret's safe with me." Blaine added.

"YOU SLEPT WITH SAM?" Quinn exclaimed as Rachel told her the truth. The two girls had left the hall after Rachel asked to talk to Quinn in the hallway.

"Yes, this morning. It just happened. I can't explain it." Rachel said, flustered.

"And...?" Quinn asked. Rachel seemed reluctant to answer.

"Honestly?" Rachel asked and Quinn nodded. Rachel sighed and put her head in her hands.

"It was AMAZING, Quinn. I haven't felt like I did when I was with Sam since I was with Finn. He's just such a sweet guy, and his body..." Rachel said.

"Oh, I know." Quinn agreed, remembering the time when she dated Sam years ago.

"It felt so right, Quinn, but I have these feelings for Sam but I miss Finn and being with another guy just makes me feel so guilty." Rachel admitted.

"Look Rachel, Finn would want you to move on and be happy, that's how much he loved you. Of course you can never get over him, but Sam is a great guy who has never treated a girl wrongly. Plus, Finn knew and trusted him and I can guarantee he'd look after you. Does he feel the same way you do?" Quinn asked.

"Yeah, he told me on the train here." Rachel said. Quinn took her hand.

"Go for it, girl. You deserve to be happy, and Sam will make you happy." Quinn said.

Rachel thought for a moment and then smiled.

"You did cut her off; she might have said she feels the same." Blaine said, having listened to Sam's explanation.

"She said 'but'..." Sam said, disheartened.

"I bet she's having doubts, of course she is, but she knows in her heart that she can't be alone forever. Her feelings for Finn will always hold her back; she'll always love him, but that doesn't mean she won't grow to love you as well." Blaine said.

"I don't want to replace Finn at all; I want to make her happy, just like he did." Sam admitted.

"Then go for it. Tell her that. You deserve to be happy, and Rachel will make you happy." Blaine said.

Sam thought for a moment and then smiled.

As Sam walked back inside with Blaine, who immediately returned to the disco to dance with his husband and awkward looking father-in-law, Burt, his phone buzzed.

'Store cupboard by the fire exit. ASAP. –Rachel'

Sam read the text and immediately made his way along the corridor until he saw Rachel standing by the cupboard door. She looked beautiful even after spending hours in one boiling room after another all day.

"Hi." Rachel said.

"Hey." Sam replied.

Silence.

"Look, Rachel, I need to say something. So I need to tell you that-"

Sam was cut off as Rachel grabbed his bow tie and pulled him in for a kiss. Sam immediately wrapped his arms around her as the kiss deepened. The two of them leant against the wall as they continued to make out for a while before they parted, leaving them both breathing heavily.

"I deserve to be happy." Rachel whispered.

"I can make you happy." Sam whispered back.

"I know you can." Rachel said. Sam kissed Rachel passionately again and moaned as Rachel kissed back and bit his lip. She untied his bow tie and started unbuttoning his shirt as Sam threw his jacket off. Still kissing the now half-naked Sam, Rachel felt for the door handle opened the door of the cupboard, sending the two of them flying inside the small space. Sam unzipped Rachel's dress as Rachel pulled Sam's trousers down and started unbuttoning his boxers. They leant against a wall and Rachel kicked the door shut. The moaning coming from the cupboard was drowned out by the loud music coming from the nearby hall.

On the dance floor, Quinn approached Blaine and hugged him. As she did so, she whispered in his ear.

"Rachel likes Sam. I told her to go for it."

"Sam likes Rachel. I told him to go for it."

They broke their hug, smiled and high fived.
