Roller Coaster
Loki was in a huff as he climbed into the roller coaster car. He kept up a running series of complaints, causing several other riders to crane their necks and have a look.
"Get over yourself – it'll be fun," Natasha said.
He rolled his eyes as the restraints were placed over their shoulders. "This is too reminiscent of my past to be fun," he growled.
After the second big drop Loki figured out the physics behind the entire ride. He was prepared for the oncoming turn and maneuvered himself so when Natasha fell against him, he was able to use it to his advantage. Their restraints disappeared and he captured her in a hungry kiss, both the speed and what their bodies were doing making them breathless.
"I knew you'd figure it out," Natasha whispered as the car slowed. "Why do you think I wanted to sit in the back?"
"Let us go again," Loki demanded.
