Chapter 1: The Training Room Incident
The gym always smelled the same—synthetic cleaner, old sweat, and the sharp, metallic tang of ozone that lingered after a repulsor blast. Natasha moved through her routine with a mechanical precision, the burn in her muscles a familiar, almost comforting pain. Control was a language she spoke fluently, each movement a word, each set a sentence constructing the calm, impenetrable narrative of her day.
The heavy bag shuddered under a final, vicious roundhouse kick.
She was grabbing her towel when the door hissed open. The rhythm of the compound shifted, the air itself changing charge.
“Natasha? Oh, good, you’re here.”
Wanda. Natasha didn’t turn immediately, using the towel to wipe her neck, buying a second to compose her face into something neutral, friendly. Just a teammate.
“Couldn’t sleep?” Natasha asked, finally glancing over.
Wanda was already padding toward the free weights, her back to Natasha. “Too much energy. My mind… it buzzes sometimes. Physical work helps.”
Natasha’s breath caught. Stalled. The younger woman was wearing thin, grey training pants and a simple black sports bra. Under the relentless fluorescent glare, the fabric of the pants did nothing to hide the curve of her ass. Nothing. And as Wanda bent to adjust a weight plate, the light confirmed what Natasha’s treacherous, instantly firing neurons had already guessed: she wasn’t wearing anything underneath.
A wave of heat, entirely separate from her workout, flooded Natasha’s chest. She looked away, focusing on a scuff mark on the floor. Don’t. Look.
“What are you working on?” Wanda asked, straightening up. Her tone was open, guileless.
“Core. Done now, though,” Natasha said, her voice thankfully even. She should leave. Right now. This was a minefield she had no business walking through.
“Would you spot me? I’m trying to increase my bench. Steve says I rely on my powers too much for physical strength.” Wanda smiled, a little self-deprecating. It was a sweet smile. A trusting smile.
Natasha’s mouth was dry. “Sure.”
She positioned herself behind the bench, her gaze fixed on a point on the wall above Wanda’s head. Wanda lay back, settling herself, and Natasha’s careful plan evaporated. The sports bra stretched tight. The line of her throat was exposed, vulnerable. The grey fabric of the pants pulled across her hips as she planted her feet.
“Okay,” Wanda breathed, gripping the bar.
She lifted, and the first low groan punched straight through Natasha’s gut. It was a sound of pure strain, effort, pain. It was utterly unselfconscious. Wanda lowered the weight, her arms trembling slightly, and pushed back up. Another soft, pained noise escaped her lips, a faint “unngh” that was almost a sigh.
Natasha’s hands, poised to assist, curled into fists. Every moan was a lit match tossed on the kindling of her restraint. She could see the tension in Wanda’s abdomen, the shift of muscles under smooth skin. This was an exquisite, private torture.
“One more,” Wanda gasped, her voice strained.
“You’ve got it,” Natasha murmured, her own voice rough.
The bar wobbled on the ascent. Natasha’s hands came up, not touching the bar, but hovering, her fingers inches from where Wanda’s grip was slipping. She caught it, taking the weight, her arms brushing against Wanda’s as she guided it back onto the rack.
For a second, they were frozen. Wanda panting beneath her, Natasha leaning over, their faces close. The scent of Wanda’s shampoo—something like vanilla and lavender—cut through the gym smells. Natasha could see the pulse fluttering in Wanda’s throat.
“Thanks,” Wanda exhaled, turning her head on the bench pad to look up at her. Her eyes were very green, still hazy with effort. “I almost lost it.”
“You didn’t.” Natasha pushed back, putting space between them, the cold air rushing in where their body heat had mingled. “That was good weight.”
Wanda sat up, shaking out her arms. A sheen of sweat made her collarbones gleam. “It feels… primal. Just muscles and bones against metal. It’s quieter than the other stuff.”
“The power.”
“Yes.” Wanda stood, stretching her arms overhead, and the hem of her sports bra rode up, exposing a strip of toned stomach. Natasha’s eyes tracked the movement before she could stop them. “Sometimes it’s so loud in here,” Wanda tapped her temple, “that I just want to be… normal. Just a person lifting a heavy thing.”
“You’re never just that, Wanda.” The words came out harsher than Natasha intended.
Wanda’s expression softened, misunderstanding. “I know. It’s a nice fantasy, though.”
She walked over to the water cooler, and Natasha watched the way the thin grey fabric moved. Acknowledge it. Name it. Lust. Simple, complicated, devastating lust. It was a physical ache, a pull in her abdomen that was entirely separate from her workout. She had slept with marks, seduced targets, used her body as a tool and a weapon for so long that genuine desire felt like a foreign country—and this was its most forbidden province.
“Your control is better,” Natasha said, needing to say something, to be the mentor, the senior agent. Anything but what she was in that moment: a woman staring.
“When I’m not tired,” Wanda said, turning. She took a long drink, water trickling from the corner of her mouth. She wiped it with the back of her hand, a childlike gesture that shouldn’t have been sensual and yet was. “Will you show me that move? The one from the Berlin airport. Where you used the floor to slide.”
“The leg sweep. It’s about momentum, not strength.” Natasha walked to the matted area, grateful for the directive, for something to do. “Come here.”
Wanda stood opposite her, mimicking her stance. Natasha moved in slow motion, demonstrating the pivot, the drop, the scissoring kick. “Your center needs to be lower.”
She moved behind Wanda, her body automatically shifting into instructor mode. She placed her hands on Wanda’s hips to adjust her posture. The heat of Wanda’s skin bled through the damnable thin fabric. Natasha’s thumbs were just above the rise of her ass. She could feel the firm muscle, the slight tremor.
“Like this,” Natasha said, her voice close to Wanda’s ear. She applied gentle pressure, guiding Wanda down.
“Okay,” Wanda whispered. A faint blush painted the back of her neck.
Natasha removed her hands as if burned. “Now try it.”
Wanda moved. It was clumsy, off-balance. She stumbled forward and Natasha caught her, an instinctual response. Wanda fell back against her, all soft weight and startled breath. Natasha’s arms were around her, holding her upright, her front pressed flush against Wanda’s back. She could feel every contour, every breath Wanda took.
Time stretched, thin and hot.
Wanda didn’t pull away. She relaxed into the hold, her head tilting back slightly, her hair brushing Natasha’s cheek. “Sorry.”
“It’s fine.” Natasha didn’t let go. She knew she should. The correct, the professional, the safe thing was to release her and take three large steps back.
She did not do that.
One of her hands splayed across Wanda’s stomach, holding her steady. The other remained on her hip. She could feel Wanda’s heartbeat, a frantic bird against her palm. Or maybe it was her own.
“Natasha?” Wanda’s voice was small, questioning.
The sound of her name, spoken like that, broke the last seal on her control. Her resistance, the careful wall she’d spent a lifetime building, crumbled into dust. She ducked her head, her lips a breath away from the skin of Wanda’s shoulder.
“You have no idea,” Natasha whispered, the words torn from some deep, hidden place, “what you do to me.”
Wanda went very still. Not stiff, but utterly attentive. The ambient hum of the compound’s machinery faded into a distant white noise. There was only the feel of Wanda in her arms, the rapid rise and fall of her chest, and the terrifying, exhilarating silence after her confession.
Wanda slowly turned in the circle of her arms. Her expression wasn’t scared. It was wide-eyed, searching, full of a curious wonder. Her gaze dropped to Natasha’s mouth.
The air between them vanished.
A soft chime echoed through the gym, followed by FRIDAY’s placid voice. “Agent Romanoff, you have an encrypted transmission waiting in the comms room. Priority protocol.”
The spell shattered. Natasha dropped her arms, stepping back so quickly she nearly tripped. The cold, institutional reality of the gym rushed back in.
“I have to go,” she said, the words clipped, professional. The Black Widow mask was back, seamless and perfect.
Wanda just nodded, her arms wrapping around herself. “Of course.”
Natasha turned and walked to the door, every step feeling like a retreat. She didn’t look back. She couldn’t.
As the gym door hissed shut behind her, she leaned against the cool wall of the corridor, closing her eyes. Her heart hammered against her ribs. She had said it. The truth was out, hanging in the ozone-scented air between them.
And she had absolutely no idea what would happen now.
