Based on YouKu's interview where all the EXO members seemed to be feeling up each other. Especially Yixing who touched Kyungsoo's crotched, smacked his bum and kissed his cheek. 

As soon as they got back to the safety of their hotel floor, Kyungsoo delivered a strong punch to Yixing's shoulder. Yixing cried out in pain which brought a smile to Kyungsoo's face and a frown upon Jongdae's.

"You shouldn't hit your hyung, Kyungsoo-ya." whimpered Yixing as he rubbed his shoulder.

Kyungsoo glared at him. "I wouldn't have to if my hyung didn't touch my crotch, slap my and kiss my cheek without my consent. Hyung that's ual harassment."

"Xing!" reprimanded Jongdae.

"He's so cute I can't help myself." Yixing gave Jongdae the puppy dog eyes.

"You need to learn how to control your boyfriend." Kyungsoo said to Jongdae. "This is getting out of hand. There were cameras for God's sake!"

Jongdae sighed. "Firstly, he is a human being who is an adult capable of making his own decisions and taking responsibility for his own actions. Also, if I knew how to control him, don't you think I would've done it already?! Do you think I like my boyfriend groping everything that moves?!"

They both looked over to where Yixing was cuddling Joonmyun and groping his arse. When Joonmyun saw Jongdae scowling, he detangled himself for Yixing but Yixing just latched onto the next member who happened to be Baekhyun.

Jongdae pursed his lips. "He's just too ually charged. If he doesn't get rid of all that whilst dancing, then he s me into next week but if that still doesn't work, then you get this."

Kyungsoo wrinkled his nose. "Ok TMI. But why don't you him into next week?"

Jongdae gave him an unimpressed look. "Because he's one of our main dancers and we can't have him out of commission." He sighed. "Maybe I should give him permission to have with other people."

Kyungsoo's eyes widened. "Would you really be ok with that?"

"Not really but it's better than seeing him touch the other members. As long as I don't know who he's having with, it's fine. I just can't keep up with him and I know he's making the others uncomfortable."

Jongdae gave him a small sad smile and walked towards his room. Kyungsoo frowned and glanced around for Yixing. He found him trying to kiss Chanyeol's cheeks with a giggly Chanyeol trying to get him off. He walked up to them, plucked Yixing of off  him and slammed him against the wall. This caused the security team and some members who were still outside to look their way.

"Kyungsoo." Chanyeol tried to reason with him. "I know you're upset about Yixing touching you like that-"

"Shut up!" snapped Kyungsoo.

The rest of the members shared uneasy looks and the security was poised to take action if necessary.

Yixing his lips nervously. "Kyungsoo, I'm sorry-"

"Shut up!" Kyungsoo growled as he slammed him against the wall again. "Shut up and listen. Jongdae loves you. And I love Jongdae, even though he can be a little sometimes, I do love him. He's a great friend when he wants to be. I respect you a lot hyung, but you are hurting him with your antics. You are going way past the line of skinship and Jongdae can get insecure. He's actually considering letting you other people because he thinks he can't satisfy your needs. The only reason I'm talking some sense into you instead of Umin hyung, is because he didn't hear the conversation we just had but you can be sure that if he did, he'd have broken your jaw by now." Kyungsoo took a deep breath and let Yixing go. "If you keep hurting  him, we'll break you two up because this is bad for group dynamics and Jongdae's feelings. Now go and talk to him."

Yixing nodded before heading towards his and Jongdae's hotel room. When he entered, Jongdae was changing out of his suit and therefore in his boxers. When Jongdae noticed his boyfriend, he smiled at him before resuming folding his suit. Yixing walked towards him and gently took the suit out of Jongdae's hands. Before Jongdae could ask what was going on, Yixing picked him up bridal style and carried him to their bed.

Once Jongdae was laid down, he asked; "Can I please finish folding my things up before we start? You know how I like everything put back in its rightful place."

Yixing lowered his head and kissed Jongdae deeply before pulling away. "Never think that you are not enough."

"What?" Jongdae asked in confusion.

"I'm sorry if I make you feel insecure. I'll try and control my limbs from inappropriately touching anyone. But please don't suggest that you can't satisfy me and definitely never give me permission to anyone but you because I will some sense into you."

"Xing-"

"I love you Jongdae. I know I don't say it a lot but I thought that maybe expressing it would be enough, apparently it's not. I don't want to make you feel insecure because you are the only one for me. As cheesy as it sounds, you complete me in every way possible so why on Earth would you think I would need anyone else but you?"

Jongdae didn't meet Yixing's eyes. "Because you are so all the time! You take out most of your ual frustration when you dance and then on me but there is always a bit left which you take out on the members and it makes everyone uncomfortable sometimes."

"That's really your fault."

"What?!" snapped Jongdae finally meeting his eyes. "It's my fault?! How is it my fault?!"

Yixing pecked his nose and smiled cutely. "You make me so , you have no idea."

Jongdae turned red and hit Yixing's chest. "Xing!"

"It's true! Sometimes I'll be thinking of all the things I want to do to you and I want you to do to me that my body will wonder and then you get incidents like today."

Jongdae groaned and tried to hide his face in the pillow. Yixing held his chin to make him look at him again before resting his forehead against Jongdae's.

"You are always on my mind Jongdae, every second of everyday."

Jongdae rolled his eyes. "You stole that from a movie."

"You stole my heart."

Jongdae groaned. "You are so cheesy!"

Yixing smiled. "But you love me anyway."

Jongdae couldn't help but smile too. "Yes I do."

"And I love you too."

Yixing bent his head down for a kiss when Jongdae suddenly moved. "I need to put my suit away."

Yixing groaned. "Jongdae!"

Jongdae moved from under him. "Two minutes Xing, I swear."

This is longer then I planned but words just happened. Also I might make a less seious version with this event later.
