Darcy was tired. It was a Friday night and Jane had made her stay for over three hours longer than usual in order to help her record an anomaly she had found. All Darcy wanted to do was curl up with James in bed and fall asleep. But life had other plans.

Darcy made her way up to James' apartment, her feet dragging over the carpet of the hallway as she walked. It wasn't odd to see her heading straight for her boyfriend's apartment. In fact, she practically lived there, spending five out of seven nights of the week in James' bed. Darcy found it odd that the door was slightly open when but in her exhausted state she ignored it, walking into the apartment, dropping her bag at the door and slipping out of her shoes in a smooth well-rehearsed move before stumbling into the bedroom.

Only to find it already occupied.

Darcy stood frozen in the doorway, suddenly wide awake as her brain processed what was happening right in front of her. The sweaty bodies of one Captain America and the Winter Soldier we getting it on. Her boyfriend and his best friend were currently fucking. They were both buck naked, hands grasping skin and mouths tracing curves and Darcy short circuited.

Her brain stopped functioning as she took in the pornographic scene before her. She would admit to having one or two fantasies about this very sight. She was a modern girl, who could blame her? But seeing it in the flesh, and what a lot of flesh it really was, was hard to swallow. Not only did they look hot together but Darcy was starting to feel slightly hot herself. For a moment she thought she was hallucinating, but when they groaned together, reality set in.

It occurred to her that what they were doing completely betrayed the trust and relationship that she had been building with James for the past eighteen months. She felt a sharp stab in her heart at the thought that he was cheating on her. She didn't understand what would drive him to do that; hadn't realised that Steve and he felt that way about each other. Their epic bromance wasn't a bromance at all but a romance and he hadn't shared that with her.

As they moved together, getting faster and moaning loudly, the sounds of their bodies slapping together filled her ears and she felt sick to her stomach. But she couldn't look away. She was captivated by them as they built up their pleasure, not even noticing her presence. And when they came together, her heart broke into pieces. She had to lean against the doorframe to keep from falling to the floor in despair.

"God, Bucky." Steve groaned and Darcy flinched.

"Fucking hell." James said as he pushed Steve lightly so that he would roll off of him. And that was when they saw her. Darcy hadn't noticed that she was crying until a sob ripped from her throat. Her eyes locked with James's and she saw the horror there. The realisation that he'd fucked up, that he's been caught.

"Darce…" He said, his voice still silky and deep from desire and Darcy found herself again.

She ran.
