Since Tony had started going out with Loki, his understanding of “a wide variety of sexual experiences” had changed wildly. The god had thousands of years to put notches in his bedpost. He’d done things Tony blushed to think of. But on rare occasions, Tony could teach Loki something.
This starts out rather innocently. Tony is tinkering with the shoulder joint on his Iron Man armour. Loki is reading an erotic novel. He makes no secret of how much he enjoys the explicit fictional encounters, though he keeps his pants on unless they’re in the penthouse. (For Tony, seeing the fabric strain as it tries to contain his impressive cock is more exciting than having him naked.)
“Tony, what does ‘skinny dipping’ mean?” Loki asks, halfway finished reading a page.
Tony adjusts one of the cables weaving through the suit’s arm. “It means going to a lake, river, or ocean and swimming naked.”
“Why would you want that?” Loki’s dark brows furrow as he stares.
“Because it’s fun. It’s a spontaneous thing. It doesn’t have to be sexy, but it can be - with that book, I’m going to guess they fuck in the lake.”
“Thanks,” Loki says before returning to his reading.
Tony sets his wrench down. “You’ve never gone skinny dipping? We should do that sometime. Unleash that wild side I know you have.”
“We have bathhouses, which are communal spaces. We don’t swim nude in lakes because the bathwater is cleaner and warmer.”
“I thought you liked it dirty.”
“How did I know you would say that?” Loki hides his smirk behind his book. “I do believe that your jokes are getting predictable.”
“All right, then. Let’s all go out. Take you to the lake and see if we can make you a little naughty.”
“My dearest Anthony, is that a challenge?”
“It might be.” Tony shrugs, hiding his own smirk.
Loki stands, placing his paperback on Tony’s workbench. “Then I might accept.”
Tony quickly wraps up what he’s doing with his suit. He informs JARVIS that they’re taking the upgraded model for a test drive. JARVIS doesn’t raise too much of a fuss - he’s used to Tony pushing the limits of his technology. Loki dons his flight suit, a simple black suit made of Asgardian leather, and summons his mask from his pocket dimension. The golden horns on the mask give it a personality that Tony’s masks seem to lack.
Tony lets Loki climb on his back. They’re used to flying that way. (Tony would prefer to carry him bridal style, but Loki refuses to admit he finds it charming.) It’s only a short flight until they arrive at what’s quickly becoming a favourite camping spot for them. This small wooded area is difficult to reach by road, but easy to find via the air. The Florida temperatures mean that even in winter, it’s never too chilly for a bit of outdoor amusement if someone might feel inclined. If they’re not, Tony’s built a cabin just big enough for two people. A sparkling clear lake is next to the camping area. Most of the time, they use it to get water, but now it has a different purpose.
Tony lands carefully, minding the grass. They’re facing the lakeshore. When Loki steps down, he takes in the moss-scented air. Tony disassembles the suit as soon as he has space. It folds into a neat carrying case at his feet. He tucks it under a log.
“Race you to the water,” Tony says, already stripping out of his shirt.
The competition helps Loki run faster. He uses magic to make the rest of their clothes disappear. Chilly lake water quickly comes up to his waist. He dives under the surface, letting his hands graze the rocks on the lake bed. When he resurfaces, Tony is grinning. He grabs Loki by the arms and pulls him close. Their kiss is wet and brief. Tony’s already starting to get hard.
“You’re quite shameless.”
“Give yourself a minute,” Tony says, smoothing Loki’s hair. “We’re going to be like that couple in your book soon.”
“Oh, they never get to the lake. They get together in the car instead.”
“More fun for us, then.”
Loki raises an eyebrow. “I’m not sure what you mean.”
“You’ll pick it up,” Tony smirks. The real question is: what should he do first?
