It just happened one night. They got home from schedules, all six of them beyond exhausted, and Chanyeol decided to skip showering because he was just so tired. As he waited for Baekhyun to come back from his shower, he slipped into the oversized t-shirt he wore to sleep and collapsed on his bed.

He wasn’t prepared for what happened when Baekhyun did enter the room, dressed similarly to Chanyeol (the shirt he wore was, in fact, one of Chanyeol’s), his hair still wet and his eyes drooping with tiredness. He wasn’t at all prepared for the jolt his stomach gave and the sudden energy that flooded his body.

He moved on autopilot as he stood up and before he even knew what was going on, he had Baekhyun pressed against the door. Little electric shocks ran through his body as he connected his lips to the other’s, only intensifying when Baekhyun kissed him back.

He was kissing Baekhyun. And Baekhyun was kissing him back.

He pulled away as if he’d been burnt when he realized what he was doing, but Baekhyun followed. “No,” he whimpered as he wrapped his arms around Chanyeol’s neck and pulled him down so he could kiss him again, and Chanyeol immediately surrendered.

Baekhyun’s mouth felt like heaven as it yielded under Chanyeol’s. The tiny little noises of pleasure that escaped Baekhyun’s mouth made Chanyeol gasp and pull him closer, wanting everything at once.

He wasn’t sure how they made it, but they eventually landed on Chanyeol’s bed, side by side with their lips still interlocked. Their legs tangled and they pulled each other closer, both equally as desperate. They parted for air, sharing the same oxygen with just a few millimeters between their lips, before they started kissing again. It was like they couldn’t get enough, they needed more, they needed everything.

Eventually they had to stop. Their lips were starting to get numb, swollen red and shiny with saliva, and all Chanyeol could taste on his tongue was the mint toothpaste they both used and BaekhyunBaekhyunBaekhyun.

They were breathing heavily as they looked into each other’s eyes, but Chanyeol’s eyelids closed when Baekhyun brought a hand up to his cheek.

“Chanyeol-ah,” he whispered, “no one can know.”

Chanyeol moved in to place another kiss on Baekhyun’s cheek, this one quick and chaste.

“I know.” He placed one of his hands over Baekhyun’s heart, the other over his own. “Let’s keep our secret here.”
