Based on the current roommate(14:23) arrangement that dictates that Chen and Lay share a room. 

Jongdae stirs from his sleep when he feels a soft pressure on his lips. Somewhere in his sleep addled brain, he recognises the touch and reciprocates. Eventually, he pulls away and forces his eyes open.

"Do you always kiss people in your sleep?" asked an amused voice.

Jongdae stretched his limps out a little before stifling a yawn. "Only when they're my boyfriend." He blinked up at Yixing and pouted his lips cutely making Yixing laugh and lean down to place another light kiss on his lips. "I didn't know you were coming back today."

"Surprise." Yixing said as he kissed the tip of his nose.

Jongdae gave him a lazy smile. "Best surprise ever."

Jongdae nudged his teddy bears to the side before tugging Yixing on top of him. He bunched his hands in Yixing's vest before haphazardly throwing a leg around Yixing's waist. Yixing's hands automatically fell at the younger boy's waist and he moved down to kiss Jongdae. Lips languidly moved against each other in a slow procession, both participants much too tired to put all their energy in to it. Jongdae's hands moved from his place on Yixing's chest as the dancer leisurely traced his lips with his tongue. A hand threaded through the elder's hair as he his tongue before moving to lazily tug at his lips. Yixing's hands began caressing Jongdae's sides making the singer's t-shirt ride up. Jongdae sighed in content as Yixing's thumbs began to make circles on his hip bone.

Guessing at where this was going, Jongdae pulled away reluctantly. "Kyungsoo's in the room, we have a schedule in a couple of hours and let's be honest, we're both a bit too tired to be doing this."

Yixing smiled in understanding and stole a few more kiss before speaking. "Has Chanyeol been annoying him again?"

"When isn't Chanyeol annoying him?" Jongdae said as he pulled Yixing to lay down beside him.

Yixing tutted as he pulled the covers over the both of them. "Poor Kyungsoo. Why doesn't he just move in with us? We have a spare bed."

"I did tell him that but he said and I quote; 'Thanks but no thanks. I don't want to hear you and Yixing hyung like rabbits in heat all night long'."

"Do rabbits even go in to heats?" Yixing mused as he tried to get comfortable.

Jongdae cuddled up against him. "I don't know. Now shh, we need to get up in about 2 hours and I want some cuddling/sleeping action."

Yixing giggled but wrapped his arms around the boy and placed a tender kiss on top of his head. "I love you."

"I love you too." Jongdae managed to mumble out before he fell asleep.
