Following off of something Epic_Emma22 and I did last night for fun.

To explain this situation, the group went on a trail ride with Clint's horses, here's the order:
Horse one- Tony
Horse two- Steve
Horse three- Clint
Horse four- Nat
Horse five- Bucky
Alanza- Namya, Bruce
Alanza Is a white wolf hybrid, her wolf shift Is the size of a full grown horse, or 1.7M. Namya Is a polar bear cub hybrid and Is 13 years old currently. Namya Is Alanza's adopted daughter. Alanza scared Horse one, two and five off by threatening to eat them.

Bucky and Steve's horses walked nearly side by side on the trails ahead of the others. Their horses were still a bit panicked from whatever the she-wolf had said. Rushed galloping was heard before a brown and white spotted horse slowed In between them with Tony on Its back. Bucky rose an eyebrow, looking to the brunet out of the corner of his eye. "Nice of you to join us." He greeted sarcastically. Tony rolled his eyes, his heart rate calming. "Couldn't miss the party, now could I?" He asked In response, a smirk playing on his lips. Steve smiled at the male, shaking his head. "Isn't much of a party, but okay, Stark." He commented. Bucky decided to bring up what Tony had said before Alanza had driven his horse to join Steve's. "Tony, what did you mean by your comment earlier?" He brought up. Steve now looked curious, he had heard the others talking but didn't hear what they had said. "What did you say, Stark?" He pushed. "What comment?" Tony tried to play It off, Bucky gave him an unimpressed look. "Okay, okay! I was just commenting on what Bruce said.." He trailed off, avoiding eye contact. "And that was?" Steve silently motioned for him to continue. "He commented on how you're ahead for once and I said I don't think you'd ever be ahead In bed." Tony finished. "And then Bruce and Nat questioned him and he told them not to worry about It." Bucky added, smirking. Steve bit his tongue, sending a glare to Tony. "If I remember correctly, Stark, you were the one under me." Steve hummed, a smirk threatening to crawl onto the blond's face. Tony's face flushed, he avoided looking at the blond. Bucky's smirk grew, what the two didn't know was that he was recording their conversation. "Shut up, Rogers." The billionaire huffed, trying to gain control over his emotions. "I'm the one that should be quiet? I think you should be telling that to yourself." Steve's face grew a small smirk as he watched Tony become squirmy under his stare. Tony didn't know how to respond to that, so he became silent for once. "I think you broke him." Bucky chuckled. "Oh, I've broke him more than this." Steve winked before the three fell silent and continued on their way. Bucky turned the recording off, he'd have to give that to Bruce later. Blackmail purposes only.

A/N Welp, maybe there really Is trouble In paradise for Nat and Tony. Or, maybe this fling happened before the assassin and billionaire were together. Who knows.
Anyways,
Have a good day/night! <3
