Her head shook once more when he repeating the obvious, the fact that she couldn't have possibly known, because it still didn't make her feel better. She supposed that was what she was always doing to him, throwing logical conclusions at him despite the fact that there was no way for them to force through the wall of doubt that she had put up in her head. It wasn't the time to argue about it, though, Natasha didn't bring Steve upstairs to make him comfort her.
Her eyes closed again when she felt his hand move to her face, head tilting just slightly into his hold before turning so she could press a tender kiss against his wrist. She believed him. It was that simple, Steve said something and she believed him, she had never experienced anything like that before with anyone. Just him. Her body felt stiff with tension, the overwhelming sense of being wrong hanging over her head, but when she saw that light smile cross his face before he leaned back into her Natasha felt it start to melt once more. She couldn't remember the last time she saw Steve smile without knowing that there was force behind it, but that one was genuine. Maybe this was a bad idea, but for right now, she was convinced that it was the right thing to do.
The feel of his hand was surprising to her, but all of this was surprising. Steve took his risks on the field but when he was off of it he was a reserved man, chances weren't something he liked to take unless his life was at at stake. Which she saw the irony in. She also knew that he wasn't well versed when it came to women. She didn't know what his experience was, but she definitely knew what it wasn't, and that was a whole new level of concern. She probably should have moved his hand away to keep it on top of her shirt but she was too far gone by now, she didn't care what contact they had, she just craved the contact. This place destroyed a person. Natasha was used to loneliness, but not like this. She was surrounded by people and still felt abandoned in her own head, and although that was no different than how it usually was, the environment was so much harsher that she actually found herself craving companionship. So maybe she was making the wrong choices, but for the first time in her life Natasha didn't seem to possess the will power to pull herself back. She moved further into him, encouraging the way his hand moved up her bare back, and her own slipped beneath his shirt to creep its way up his waist and around until the hard muscle of his chest was beneath her warm fingertips.
She was too close. Natasha was teetering on a dangerous brink, and she made one last effort to clear her head by pulling away from him once more with a breathless sound. "...You should sleep," she forced out, showing no sign of moving further. "You haven't slept in days, Steve, you need it. You know you do."
