Summary: Coopbastian oneshot (a prompt I filled on Tumblr). Sebastian and Cooper go to an amusement park and the outcome was not expected at all.

Marry Me
A Coopbastian Oneshot

"You're insane," Sebastian said, looking up at the giant rollercoaster, "Have fun."

"Nope," Cooper grabbed his hand, "You're coming with me."

"Ha, you're funny," Sebastian snorted and Cooper started dragging him towards the entrance.

"I take that back!" Sebastian said quickly, "You need to be in the nut house! Let me go!"

"No, I'll get scared if I don't ride with my boyfriend," Cooper kissed him as they walked down the dark hallway, "I love it here in October. It's all the Halloween shit and it's scary."

"R-Right," Sebastian growled, "Fun."

Cooper laughed quietly.

"What?" Sebastian asked.

"You're cute," Cooper said as they got in line.

"Sebastian Smythe is not CUTE," Sebastian snorted.

Cooper laughed, "Yes he is. His boyfriend said so."

Sebastian glared at him and his eyes widened when the rollercoaster pulled up, "I changed my mind."

Copper rolled his eyes, pulling him into the car, "You need to switch me spots."

"Why?" Sebastian demanded.

"I'm bigger than you and I don't want to crush you. Blaine and I made that mistake when we were little," Cooper said, "And he said he made it with Kurt last month."

"Gay-face is taller," Sebastian muttered.

Cooper pinched his hip, "It's Kurt and he is about ten pounds lighter than Blaine. I swear the kid is anorexic but he can pack it on."

Sebastian rolled his eyes, "If you want to have some fun tonight, stop talking about KURT or I'll never get hard."

Copper rolled his eyes and the bars went down and he felt Sebastian's hand slip in his, "Are you scared?" he asked.

"No," Sebastian croaked.

Cooper laughed, putting his arm around him, "I'll protect you."

"You don't need to protect me," Sebastian said. He had the same look a cat would have if it got thrown into water.

The rollercoaster started and went down a hill instantly.

Sebastian yelped and hid his face in Cooper's shoulder.

Cooper looked at Sebastian and smiled. The twenty two year-old was everything he wanted. There was a person under Sebastian's hard shell and he was proud to say he was the one that broke it…and made him stop drinking so much coffee and alcohol and switch to fruit juice.

"C'mon!" Cooper called, "Open your eyes!"

Sebastian shook his head.

Cooper laughed, "It's not like you'll fall out."

Sebastian smiled into his neck, "I like cuddling with you though."

Cooper wrapped his arms around him until they stopped and he shook him, "Hey, Seb. We stopped."

Sebastian looked up as they both got up from the cart.

"Hey!" a worker called to Cooper and held up a little black box, "You dropped this!"

Sebastian looked at him wide eyed.

"Oh…" the worker said in shock, handing Cooper the box.

Copper caught Sebastian's arm before they left, "Marry me."

"What?" Sebastian whispered.

"I want you to be my husband," Cooper whispered.

Sebastian stared at him for a second and kissed him, "Okay," he breathed out, "Yes."
