Chapter 1 - Soles on the Trail

Pepper’s breath came steady through her nose, matching the rhythm of her footfalls on packed earth. The path climbed here, enough that her calves pulled taut with each push through the stand of Douglas firs.

Natasha ran three strides ahead, red hair caught back in a ponytail that swayed with her gait. She moved like she always did—economy in every motion, no wasted energy. Her shoulders stayed level. Her footfalls barely disturbed the carpet of shed needles.

“Maria’s seeing someone,” Natasha said over her shoulder, voice even despite the incline.

Pepper’s lungs expanded against her sports bra. “Since when?”

“Two weeks. Maybe three.” Natasha glanced back, green eyes glinting in the filtered sunlight. “She’s being cagey about it.”

The trail leveled out and Pepper closed the gap between them, matching Natasha stride for stride. Sweat trickled down her spine, dampening the small of her back where her tank top clung. “That’s not like her.”

“No.” Natasha’s jaw worked. “It’s not.”

They ran in silence for a stretch. The forest opened up on their left, revealing a ravine where morning fog still pooled in the hollows. Cool air drifted across Pepper’s face, welcome against the heat building in her cheeks. Her quads burned from the sustained effort.

Natasha pulled ahead again. Not by much, but enough to sting.

Pepper watched the controlled flex of Natasha’s calves, the precise placement of each foot. She pushed harder, driving through the balls of her feet, forcing her lungs to take deeper pulls of pine-scented air. The gap closed. Natasha’s ponytail swayed close enough to reach.

“You’re keeping up better,” Natasha said.

“I’ve been running more.” Pepper’s words came clipped.

“I noticed.”

The trail dipped, then rose again. Pepper’s heart hammered against her sternum, in her throat, in her temples. Her running shoes struck stone, then dirt, then a patch of exposed roots she had to adjust for mid-stride. The micro-corrections pulled at her ankles, demanded attention from stabilizing muscles that were already fatigued.

Natasha eased her pace, subtly enough that most people wouldn’t register. But Pepper felt it in the shift of relative position, the way she no longer had to strain to maintain the distance between them.

“Don’t slow down for me,” Pepper said.

“I’m not.”

“You are.”

Natasha’s shoulders lifted in a shrug. “The view’s better from here.”

Heat crept up Pepper’s neck. She focused on the trail, on the placement of her feet, on the burn spreading through her thighs.

They rounded a bend where the forest thickened. The temperature dropped several degrees in the shade. Pepper’s skin prickled with the change, sweat cooling too quickly. Her breath misted.

“Tony mentioned you closed the Singapore deal,” Natasha said.

“Yesterday afternoon.” Pepper’s lungs protested the additional demand of speaking. “Their legal team tried to renegotiate at the last minute.”

“But you didn’t let them.”

“No.”

Natasha glanced back again, a smile tugging at the corner of her mouth. “Of course you didn’t.”

The trail narrowed. Pepper fell back into single file, watching the rhythmic pump of Natasha’s arms, the controlled rotation of her torso. Everything efficient. Everything measured.

Pepper’s left hamstring tightened. Not quite a cramp yet, but the warning of one. She adjusted her gait, tried to work through it. The muscle complained, pulling wrong with each extension.

Her steady inhale-exhale pattern roughened. Her footfalls grew heavier, less precise. A root caught the edge of her shoe and she stumbled, caught herself with a hard step that jarred up through her knee.

Natasha stopped.

Pepper pulled up beside her, hands on her hips, chest heaving. Sweat dripped from her chin. Her legs trembled, fine muscle fibers pushed past their comfortable limit.

“You alright?” Natasha asked.

Pepper nodded, not trusting her voice yet. She bent forward, palms braced against her thighs, trying to force oxygen deeper into her lungs.

“There’s a clearing just ahead,” Natasha said. “Want to take a break?”

Pepper straightened. Her hamstring twinged again. “Yeah. Okay.”

The clearing was barely twenty feet across, ringed by sword ferns and young hemlocks. A fallen log provided seating, its bark soft with rot in places but mostly solid. Pepper lowered herself onto it, grateful when it held her weight.

Natasha stood a few feet away, barely winded. Her chest rose and fell, but the rhythm stayed controlled. “How far do you want to go today?”

“However far you planned.” Pepper stretched her legs out, feeling the pull in her hamstrings, her calves. “I just need a minute.”

“Take your time.” Natasha’s gaze tracked down to Pepper’s feet. “Your shoes fitting alright?”

Pepper looked down at her running shoes—expensive, fitted professionally, barely two months old. “Why?”

“You were favoring your left side for the last quarter mile.”

Of course she’d noticed. Natasha noticed everything.

“They’re fine,” Pepper said. “I might have a hot spot forming.”

Natasha moved closer, crouched in front of her. “Let me see.”

“Nat, it’s—”

“Let me see.”

Pepper leaned back against a section of sturdier bark, watched Natasha’s nimble fingers work the laces of her left shoe. The Aesics came free and Natasha slipped it off, then peeled away the moisture-wicked sock.

Cool air hit Pepper’s damp skin. She curled her toes reflexively.

Natasha’s fingers pressed against the ball of Pepper’s foot, testing. “Here?”

“A little lower.”

The pressure shifted, found the spot where friction had been building. Pepper’s breath caught.

“Tender?” Natasha asked.

“Some.”

Natasha’s thumb circled the area, gentle at first, then with more intention. She cradled Pepper’s heel in her other hand, supporting the weight. Her fingers were warm, a bit rough at the tips.

The tension in her arch started to release, and the ache in her sole spread outward from where Natasha rubbed.

“Other foot too?” Natasha’s eyes flicked up, held Pepper’s gaze.

Pepper swallowed. “If you don’t mind.”

Natasha reached for the right shoe without breaking eye contact. The laces loosened under her fingers. The shoe came away, then the sock, both set beside their partners on the forest floor.

This time Natasha used both hands, thumbs pressing into Pepper’s arch while her fingers wrapped around to the top of her foot. She worked upward from heel to toes, finding knots of tension and coaxing them loose.

Pepper’s head tipped back. Her eyes closed. The sensation traveled up her calf, into her knee, sparking a warmth low in her belly.

Natasha’s grip tightened fractionally. Her thumbs dug deeper, following the line of tendon and muscle. “Better?”

“Mm.”

The massage continued. Natasha’s hands moved with purpose, reading the responses in Pepper’s breathing, in the small shifts of her weight. When she found a tight spot, she lingered there, applying steady pressure until the fibers yielded.

Pepper’s right hand gripped the log beneath her. Wood grain pressed into her palm. Her other hand rested on her thigh, fingers splayed.

Natasha’s thumb traced up the inside edge of Pepper’s foot, following the arch to the base of her big toe. She applied pressure there, circular motions that sent heat radiating outward.

Pepper’s lips parted. Her breath came slower, deeper.

Natasha switched feet, giving the left the same attention. Her fingers slid between Pepper’s toes, separating them, creating space before releasing. The stretch was exquisite.

“You run yourself too hard,” Natasha said quietly.

Pepper opened her eyes. Natasha was watching her, hands still cradling her foot.

“So do you,” Pepper said.

“That’s different.”

“How?”

Natasha’s thumb pressed into the center of Pepper’s sole. “I was trained for it. Built for it.” Her fingers flexed, grip firm. “You just refuse to quit.”

The weight of Natasha’s attention was palpable, the focus that usually sharpened around weapons and targets now directed at her.

Natasha’s hands shifted. Less therapeutic now. More exploratory. Her fingers traced the curve of Pepper’s ankle, the hollow below the bone. Her touch lingered there, warm and deliberate.

Pepper’s pulse jumped in her throat, in her wrists, in the sensitive arch where Natasha’s palm still pressed.

“Tell me to stop,” Natasha said.

Pepper held her gaze. “I don’t want you to stop.”

Natasha’s breath changed. Deeper. Slower. She lowered her head, red hair falling forward to curtain her face. Her lips brushed the top of Pepper’s foot, barely contacting the skin.

Pepper’s fingers tightened on the log.

Natasha kissed her instep. Soft. Gentle. Then again, lower, where the arch began its curve. Her breath warmed the skin.

“That’s—” Pepper began.

Natasha’s tongue traced a line from heel to ball, wet and silken.

Pepper’s hips shifted forward. The log scraped against the back of her thighs. Her free hand moved to Natasha’s hair, fingers tangling in red strands.

Natasha’s mouth opened wider. She took Pepper’s big toe between her lips, tongue swirling around it. The wet heat made Pepper’s cunt clench. She tugged at her handful of red hair.

Natasha hummed approval. The vibration traveled through skin and bone. She sucked harder, cheeks hollowing, before releasing with a soft pop. Her full lips moved to the next toe, then the next, giving each the same loving attention.

Pepper’s breathing roughened. She watched Natasha work, watched the elegant line of her neck as she bent forward, the flex of her jaw, the way her eyes closed in concentration.

“Fuck,” Pepper whispered.

Natasha’s eyes opened. Green and intent. She pressed a kiss to Pepper’s ankle, then higher, teeth scraping lightly against tendon. Her hands slid up Pepper’s calf, kneading the tense muscles.

Pepper spread her legs wider. The position pulled at her hamstrings, already fatigued, but she didn’t care. She needed the space, needed cool air against the damp fabric between her thighs.

Natasha’s tongue traced the curve of Pepper’s arch again, long strokes that went from heel to toe. She paused at the ball of the foot, sucking at the tender skin there. Her teeth grazed, not quite biting.

Pepper’s hand in Natasha’s hair tightened, controlling the angle, the pressure.

“Both feet,” Pepper said, voice rough. “I want your mouth on both of them.”

Natasha pulled back to look up. Her lips were wet, flushed darker. “Yes.”

She shifted position, bringing Pepper’s left foot up to join the right. She cradled both heels in her palms, thumbs pressing into arches. Her tongue found the space between Pepper’s ankles, licked a stripe up to where the bones pressed together.

Pepper made a sound low in her throat. Her fingers dug into wood, into hair. Heat coiled tighter in her belly, spreading lower.

Natasha kissed her way across both feet, alternating between them, mouth hot and eager. She took three of Pepper’s toes at once, sucking hard enough that Pepper’s back arched off the log. Saliva slicked her skin. The forest air cooled it, sent shivers racing up her legs.

“Good girl,” Pepper heard herself say. The words both foreign and perfect. “Keep going.”

Natasha moaned. The sound vibrated through Pepper’s bones. Her tongue worked faster, more desperately, painting wet trails across sweaty skin. She pressed kisses to Pepper’s soles, her heels, the delicate web between her toes.

Pepper leaned forward, bringing her face closer to Natasha’s bent head. She tugged the red ponytail, forcing Natasha to look up.

“You’re going to clean them,” Pepper said. “Every inch. I want to feel that tongue everywhere.”

Natasha’s pupils were blown wide. She nodded, mouth still pressed to Pepper’s instep.

“Say it.”

“Yes.” Natasha’s voice came out ragged. “I’ll clean them. I’ll use my tongue everywhere.”

“Everywhere?” Pepper’s fingers tightened in red hair.

“Everywhere.”

Pepper released her grip, leaned back. “Show me.”

Natasha bent with renewed fervor. Her tongue traced each toe individually, dipping between them, dragging through the spaces that had been compressed in socks and shoes all morning. She licked the creases where toes met foot, sucked at the thin skin there.

Pepper’s thighs trembled. The muscles burned, but the ache blurred into a throb between her legs and made her hips rock forward.

Natasha’s mouth moved to Pepper’s sole. She licked long strokes from heel to toe, over and over, coating the skin with saliva. When she reached the ball of the foot she sucked hard, teeth scraping.

“Fuck.” Pepper’s free hand moved to her own thigh, nails digging in through the stretchy fabric. “Don’t stop.”

Natasha didn’t. Her tongue explored every curve, every callus, every sensitive hollow. She paid special attention to the arch, that tender span between heel and ball. Her lips sealed around it and she sucked, pulling blood to the surface, marking territory.

Pepper’s vision blurred at the edges. She was distantly aware of birds calling somewhere overhead, of wind moving through fir branches, but those sensations felt abstract, unimportant. Everything narrowed to the wet heat of Natasha’s mouth, the skilled movements of her tongue, the obscene sounds of outdoor foot worship.

Natasha switched feet again, giving the right the same thorough treatment. Saliva dripped down Pepper’s ankle. Natasha caught it with her tongue, slurped it back up.

“You look good like this,” Pepper said. “On your knees. That cocky mouth full of my toes.”

Natasha whimpered. The sound went straight to Pepper’s clit.

“You like it, don’t you?” Pepper pressed the ball of her foot against Natasha’s lips. “Being put to filthy use.”

Natasha’s tongue darted out, licked across the curve. “Yes.”

“Yes what?”

“Yes, I like it.” Natasha’s breath came in pants. “I like being used.”

Pepper smiled. Cold and pleased. “Then open wider.”

Natasha’s jaw dropped. Pepper fed her toes in slowly, watching them disappear between those famous plump lips. First two, then three, then four. Natasha’s eyes watered but she didn’t gag, just accepted the intrusion and started sucking.

“That’s it.” Pepper’s voice dropped lower. “Take them. Get them wet.”

Natasha hollowed her cheeks. Her tongue worked between Pepper’s toes, thorough and desperate. Drool escaped the corner of her mouth, tracked down her chin.

Pepper pulled her foot back, watching the string of saliva connect her toes to Natasha’s lips. It stretched, held, finally broke.

“Messy,” Pepper observed. “You’re making a mess of yourself.”

Natasha’s chest heaved. “I’m sorry.”

“Are you?” Pepper pressed her wet foot against Natasha’s cheek, smearing moisture across flushed skin. “I don’t think you are.”

“No.” Natasha turned her face into the touch. “I’m not sorry.”

“That’s better.” Pepper dragged her toes across Natasha’s lips. “I want you honest when you’re down there.”

Natasha’s tongue caught Pepper’s big toe, guided it in deep. Her eyes stayed locked on Pepper’s face, green and glassy.

Pepper watched her work for a long moment, enjoying the sight. Natasha Romanoff—deadly, precise, always in control—reduced to kneeling in dirt and pine needles, mouth wrapped around toes, making desperate sounds.

“You look like a whore,” Pepper said. “Anyone could walk by. See you on your knees, sucking my feet like you’re starving for it.”

Natasha moaned. Her hips rocked forward, seeking friction against nothing.

“Would you stop?” Pepper mused. “If someone came down the trail right now. Would you stop sucking feet or would you keep going?”

Natasha’s answer muffled around Pepper’s toes but the meaning was clear. She’d keep going. Nothing could make her stop.

“Filthy slut.” Pepper’s smile widened. “Show me how filthy. Put your tongue between my toes. Clean all that sweat out.”

Natasha obeyed immediately. Her pink tongue pushed between Pepper’s big toe and second toe, licking deep into the crevice. She worked thoroughly, coating every inch with saliva before moving to the next space.

Pepper’s free foot pressed against Natasha’s chest, against the rapid rise and fall beneath sports bra and damp tank top. “You’re going to lie down now.”

Natasha pulled back, lips red and glistening. “What?”

“On your back. On the ground.” Pepper gestured with one foot. “Now.”

Natasha stared at her for a heartbeat, processing. Then she moved, lowering herself to the forest floor. Pine needles and moss compressed under her weight. She settled on her back, arms at her sides, looking up at Pepper with wide eyes.

Pepper stood. Her legs protested the movement, muscles stiff from the run and the sustained position. She ignored the complaint, stepped over Natasha’s prone form.

The angle put Pepper in a position of complete dominance. She looked down at Natasha beneath her, red hair spread against dark earth, chest heaving, lips parted.

“Stay still,” Pepper said.

She lowered one foot, placed it carefully on Natasha’s sternum. Bone and muscle yielded under her weight. She pressed down until Natasha’s breath caught.

“This is what you wanted,” Pepper said. Not a question.

“Yes.” Natasha’s hands fisted at her sides. “Please.”

Pepper shifted her weight forward. Her foot slid up, toes dragging across the dip at the base of Natasha’s throat. She paused there, pulse hammering against her sole.

Natasha’s eyes fluttered closed.

“Look at me,” Pepper commanded.

Green eyes flashed open.

“Good.” Pepper moved her foot higher, across Natasha’s jaw, up to her cheek. She pressed down firm enough to make her head turn. “Open.”

Natasha’s lips parted.

Pepper dragged her toes across that open mouth, feeling tongue and teeth and breath. Natasha’s head turned, trying to catch the digits, suck them in.

“I didn’t say you could do that,” Pepper said.

Natasha froze.

“Just keep your mouth open. Let me feel it.”

Natasha’s jaw hung slack. Drool gathered at the corners of her mouth.

Pepper traced the outline of those pillowy lips with her big toe, slow and steady. She dipped inside, just past teeth, touching the wet heat of tongue. Then she pulled back, smeared the moisture across Natasha’s chin.

“You’re leaking,” Pepper observed. “Can’t even control your own drool.”

Natasha made a sound—half whimper, half moan.

Pepper sat back down on the log, Natasha’s head between her knees. The strain in her legs had become irksome, but luckily she had a good little red-headed foot slave to ease the discomfort.

Her left foot found Natasha’s chest, pressing down on her left breast. The firm flesh compressed under her sole, the hard point of nipple discernible even through layers of fabric.

“Sensitive?” she asked.

“Yes.” Natasha’s voice came out strangled.

Pepper applied more pressure, rolling her foot in slow circles. Natasha’s back arched off the ground, pressing up into the contact.

“Greedy Russian bitch,” Pepper said. But she didn’t stop. She worked Natasha’s breast with her foot, enjoying the weight and softness of it, the way Natasha’s breathing changed—sharp inhales, shaky exhales.

Her other foot lifted, pressed down on Natasha’s forehead, and slid down her upturned face, across her jaw to her throat. She pressed there again, loving the vulnerability.

“Stick your tongue out,” Pepper said.

Natasha’s tongue emerged, pink and wet.

Pepper dragged the heel of her foot across it, slow enough to sense texture, to coat her skin with fresh saliva. “That’s better. Keep it out.”

She wiped her sole on Natasha’s extended tongue, using it like a washcloth. Back and forth, heel to toe, making sure every inch made contact.

Natasha’s eyes watered. Her tongue trembled but stayed extended, obedient.

“Such a good little slave,” Pepper murmured. “So useful.”

She moved her foot to Natasha’s other breast, gave it the same attention. Natasha writhed beneath her, hips bucking uselessly.

“Stay still,” Pepper said sharply.

Natasha went rigid, fighting visible tremors.

Pepper looked down at her work. Natasha’s face was flushed deep red, lips swollen, chin wet with drool and saliva. Her chest heaved under Pepper’s feet. Her thighs pressed together, seeking friction.

“You’re a mess,” Pepper said. “Look at you. Covered in spit. Desperate.”

“Please,” Natasha managed.

“Please what?”

“Please use me. Any way you want.”

The words sent heat coursing through Pepper’s core. She shifted her weight, placed both feet on Natasha’s chest. The pressure made Natasha’s breath wheeze out.

“I’m going to walk on you,” Pepper said. “Step on that pretty face. You’re going to stay exactly where you are and take it.”

Natasha’s pupils dilated further. “Yes. Please. Trample me.”

Pepper tested her balance, then stepped up from the log and fully onto Natasha’s chest. The position was precarious—she had to engage her core, keep her knees bent. But Natasha’s athletic body provided surprisingly solid support.

She looked down. The view was intoxicating. The mighty Black Widow spread beneath her, pinned under her feet, looking up with desperate want.

Pepper shifted her weight to her left foot, lifted her right. She placed it carefully on Natasha’s cheek, pressing down. The Russian’s face compressed, cheekbone prominent against her arch.

“How does that feel?” Pepper asked.

“Good.” Natasha’s voice was muffled. “So good.”

Pepper transferred weight, pressed harder. Natasha’s head turned with the pressure. “You like being stepped on.”

“Yes.”

“Walked on like a floor.”

“Yes.”

“Used like furniture.”

“Yes!”

Pepper moved her foot to Natasha’s mouth again. Toes pressed against closed lips. “Open.”

Natasha opened. Pepper fed her toes in, all five this time, cramming them past teeth. Natasha’s jaw stretched wide. Tears leaked from the corners of her eyes, but she accepted the intrusion and started sucking.

“There you go,” Pepper said. “Choke on them.”

Natasha’s throat worked. Her tongue struggled to move with her mouth so full but she tried, desperate to please.

Pepper’s other foot pressed down on Natasha’s right breast, grinding. The rapid tattoo of heartbeat came prominent through her sole.

She pulled her toes free of Natasha’s mouth with a wet sound. Saliva strung between them, dripped down Natasha’s chin.

“Disgusting,” Pepper said. The word came out affectionate, almost tender. “You’re absolutely disgusting.”

“I know.” Natasha’s voice broke. “I know. I’m sorry.”

“Don’t apologize.” Pepper stepped down, planted both feet on either side of Natasha’s head. She looked down into large green eyes. “I like you like this. Ruined.”

She gathered saliva in her mouth. Let it pool on her tongue.

Natasha’s eyes widened.

Pepper leaned forward, pursed her lips. Let the glob of spit fall.

It landed on Natasha’s forehead, thick and viscous. Slid down the bridge of her nose.

Natasha moaned. Her hips bucked off the ground.

Pepper gathered more, spit again. This time it hit Natasha’s cheek. Then again, landing on her parted lips. Natasha’s tongue darted out, caught some of it, pulled it into her mouth.

“You like that?” Pepper asked. “Being spit on?”

“Yes.” No hesitation. “Yes. Please. More.”

Pepper obliged. She spit across Natasha’s face—forehead, nose, cheeks, chin. Watched the moisture coat pale skin, mix with sweat and tears and drool.

“Open your mouth,” she commanded.

Natasha’s jaw dropped wide.

Pepper leaned down further, aimed carefully, spit directly into that open mouth. Watched the glob land on Natasha’s tongue, pool there.

“Swallow it.”

Natasha closed her mouth. Her throat worked visibly.

“Good girl.” Pepper spit again, then again. Each time Natasha accepted it, swallowed it down. “Such a good little slut.”

The word made Natasha’s whole body shudder. Her hands came up, grabbed at Pepper’s calves.

“Did I say you could touch?” Pepper asked.

Natasha’s hands fell away. “No. Sorry. I’m sorry.”

“I know you are.” Pepper said. “But you’re going to have to earn the privilege back.”

“How?” Natasha’s voice was desperate. “Tell me how.”

Pepper considered. Her gaze tracked down Natasha’s body—the damp tank top, the running shorts, the lean muscle of her thighs.

“Pull your top up,” Pepper said. “I want to see your tits.”

Natasha scrambled to obey. She yanked the tank top up, sports bra with it, exposing full pale breasts. Her nipples were hard, dark pink against white skin.

“Nice,” Pepper said. She stepped back onto Natasha’s chest, both feet planted between her breasts. Strong ribs flexed beneath her weight. She slid one foot onto her left breast, pressing the soft tissue flat beneath her sole.

Natasha cried out. Her back arched.

Pepper rolled her foot, the nipple dragging against her arch. “Sensitive?”

“Yes. Fuck. Yes.”

Pepper transferred to the right breast, gave it the same treatment. Natasha thrashed beneath her, hands fisting in pine needles and moss.

“Stay still or I stop,” Pepper warned.

Natasha went rigid again, every muscle locked tight. Small tremors ran through her frame but she didn’t move.

“Good.” Pepper walked across Natasha’s chest, tiny steps that covered every inch of exposed skin. Ribs and breastbone and soft flesh beneath her feet, accompanied by Natasha’s rapid breathing, the heat radiating from her body.

She moved higher, placed one foot on Natasha’s throat again. Pressed hard enough to make the windpipe shift beneath her sole.

“You trust me,” Pepper said. Not a question.

“Yes.” It came out a half croak. “With everything.”

The words settled in Pepper’s chest, warm and weighty. She eased off the throat, stepped down to straddle her waist.

Natasha looked up at her. Face a mess of spit and tears and drool. Green eyes wild with need. Chest heaving, breasts flushed pink from attention.

She looked perfect.

Pepper gathered more saliva, leaned down, spit across both breasts. Watched the moisture coat pale skin, drip down the curves.

“You’re mine now,” Pepper said. “My toy. My plaything to use.”

“Yes.” Natasha’s voice broke. “Yours. I’m yours.”

Pepper spit again, this time into Natasha’s open gasping mouth. “Say it again.”

“I’m yours. I’m your toy. Your plaything.” Natasha swallowed, tongue darting out to wet her lips. “Use me however you want.”

Power surged through Pepper, bright and electric. She’d given orders in boardrooms, commanded respect in meetings with world leaders. But this was different. This was the Black Widow. Natasha Romanoff—dangerous, lethal, always in control—willingly giving up that control. Offering herself as a slave.

“Roll over,” Pepper said, easing the weight off to give her room.

Natasha flipped, face pressed into moss and needles. Her red hair spread across her back. The subtle knobs of her spine protruded through her tank top and bare skin.

She stepped onto Natasha’s back, one foot between her shoulder blades. The position brought her higher, made her balance more precarious.

“How’s that feel?” she asked.

“Heavy.” Natasha’s voice was muffled. “Don’t stop.”

Pepper walked up Natasha’s spine, each vertebra a hard point beneath her feet. Another massage for her tired soles. When she reached the base of Natasha’s neck she paused, pressing down with her heel.

Natasha made a sound—pleasure and pain mixed together.

Pepper stepped down onto the back of Natasha’s head, pinning her face to the forest floor. Firm enough to keep her there.

“Don’t move,” she said.

She stood like that for a long moment, one foot on Natasha’s head, the other on her upper back. Breathing forest air. Claiming her trophy. Owning her bitch.

Then she turned, walked down the length of Natasha’s body. Over her hips, her thighs, her calves. Nothing but lean muscle beneath her feet, powerful and lithe.

When she reached Natasha’s ankles, she turned and walked back up. Keeping her balance on the narrow surface was a real challenge, but her slave remained dead still beneath her, making the journey a bit easier. This time she paused at Natasha’s ass, pressed both feet into the generous curve of dense muscle.

“You’ve got a great ass,” Pepper observed. “Shame to waste it.”

She stepped down, circled back to Natasha’s head. “Roll over again.”

Natasha rolled. Back on the ground, face tilted up. Waiting.

Pepper lowered herself, straddled Natasha’s face. Not sitting, just hovering close enough that Natasha could smell the heat of her through the running shorts.

“I think I’m done with your mouth on my feet,” Pepper said. “Time to put it somewhere else.”

Natasha’s hands came up, gripped Pepper’s thighs. “Please. Let me taste you.”

“Not yet.” Pepper straightened, stepped back. “We’re going to finish our run first.”

Natasha made a sound of protest.

“That’s an order,” Pepper said. The words came out sharp, final. “You’re going to get up. We’re going to run back to the house. And then—” she paused, let the anticipation build, “—then maybe I’ll let you finish what you started.”

Natasha stared up at her, chest heaving, face a mess, want and frustration warring across her features.

“Understand?” Pepper asked.

“Yes.” The word came out ragged. “I understand.”

“Good girl.” Pepper reached for her discarded socks and shoes. “Get yourself together. You look obscene.”

Natasha sat up slowly, wiping at her face with shaking hands. It didn’t help much. The evidence of what they’d done was written all over her—swollen lips, flushed skin, wet smears down her cheeks and chin.

Pepper pulled her socks on, then her shoes. The compression felt strange after having her feet bare and worshiped. She laced them up tight.

When she looked up, Natasha was standing. She’d pulled her sports bra and tank top back down. Her hair was disheveled, ponytail half-undone.

“Fix your hair,” Pepper said.

Natasha pulled the elastic out, gathered her thick red strands with trembling fingers, secured the ponytail again. It sat crooked but serviceable.

Pepper stepped close, invaded Natasha’s space. The Russian spy smelled of sweat and arousal and forest floor. “You’re going to run behind me this time. Keep up.”

“Yes.”

“If you fall behind, I’m not slowing down.”

“I won’t fall behind.”

“We’ll see.” Pepper smiled, cold and pleased. She turned, started back toward the trail.

Behind her, she heard Natasha fall into step. Close. Eager.

Pepper picked up her pace, pushing into a full run. Her muscles protested—they’d stiffened during the break, during everything that followed. She ignored the complaint, drove harder.

The trail blurred past. Pine and fir and patches of sky visible through branches overhead. Her breath came hard and fast. Her heart hammered.

Natasha followed behind her. Steady footfalls. Controlled breathing. Keeping pace. She wouldn’t dare try to push past.

The trail sloped down, then up. Pepper attacked the incline, pushing through burning thighs and screaming lungs. At the crest she glanced back.

Natasha was there. Right on her heels. Face set in determination, eyes locked on Pepper’s back. Knowing her place.

Good.

Pepper ran harder. The trail opened up, widened. She stretched her stride, found her rhythm again. Everything else fell away—the fatigue, the ache in her hamstrings, the distraction of what had just happened. Only the movement mattered. The push and pull of muscle. The impact of foot striking earth.

The Stark mansion came into view through the trees. Modern lines and glass walls, incongruous against the forest backdrop. Pepper didn’t slow until she hit the driveway, finally letting herself pull up to a walk.

Natasha appeared beside her seconds later. Barely winded.

Of course.

They walked in silence to the front entrance. Pepper tapped in the security code, let the camera scan her face, waited for the lock to disengage. The door swung open. Cool air-conditioned atmosphere washed over her sweat-damp skin.

“Upstairs,” Pepper said. Not looking at Natasha. “Master bathroom. Get the shower running.”

She heard Natasha’s sharp inhale. “Hot or cold?”

“Hot. As hot as you can stand.”

Footsteps receded—Natasha taking the stairs two at a time.

Pepper locked the front door, reset the security. She took her time, let the moment sink in. When she finally climbed the stairs, her legs protested every step.

The master suite was exactly as they’d left it this morning. Bed made, clothes put away, everything in its place. The sound of water running came from the attached bathroom.

She stepped through the doorway. Steam already clouded the mirror, curled in the air. The shower was a massive glass enclosure, multiple heads running at full pressure.

Natasha stood outside it, tank top and sports bra already stripped off. Her hands were at the waistband of her shorts.

“Stop,” Pepper said.

Natasha froze.

Pepper crossed to her, reached out. Her fingers found the elastic waistband, slipped beneath it. Heat radiated from Natasha’s skin, a jumping pulse at her hip.

“Let me,” Pepper said.

She peeled the shorts down slowly, taking her panties with them. The shift revealed more pale skin, a neat triangle of dark red hair, the slickness of arousal coating inner thighs.

Natasha stepped out of the shorts, kicked them aside.

Pepper took a step back, looked her fill. Lean muscle and skin and want written across every line of the Russian slut.

“Get in,” she said.

Natasha stepped into the shower, into the spray. Water cascaded over her, plastering red hair to her skull, streaming down her tight body.

Pepper stripped efficiently—shoes, socks, tank top, sports bra, shorts, underwear. Left them in a pile. Stepped into the steam and heat.

The water hit like a wall. Almost too hot, on the edge of uncomfortable. It pounded against her back, her shoulders, chased away the stiffness that had settled into her cooling muscles.

Natasha stood under a different shower head, water running down her face, over her breasts, between her legs. Waiting.

Pepper moved to her. Crowded into her space. Skin met skin, slick and hot.

“Wash me,” Pepper said.

Natasha reached for body wash without hesitation. Squeezed expensive soap into her palm, worked it into lather.

Her hands found Pepper’s shoulders first. Rubbed in circles, working away tension. Down her arms, then back up. Across her collarbones, down to her breasts.

Pepper’s breath hitched when Natasha’s palms cupped her breasts, thumbs circling erect nipples. The touch was confident, purposeful. Natasha knew exactly what she was doing.

“Lower,” Pepper said.

Natasha’s hands slid down Pepper’s ribs, over the slight swell of her belly. Then around to her back, kneading at muscles still tight from the run.

“If I may... Please turn around,” Natasha said.

Pepper turned. Faced the tiled wall. Water streamed down her front now, a different shower head taking over.

Natasha’s hands worked down her spine, over her ass, squeezing. Then lower, to her thighs. Strong fingers dug into muscle, finding knots and coaxing them loose.

“You ran hard,” Natasha said against her ear. “Let me make it better.”

Her hands slid between inner thighs, washing, teasing. Not quite where Pepper needed them.

“Higher,” she commanded.

Natasha’s fingers brushed against her cunt. Feather-light.

“I said higher.”

Two fingers slid between folds, found her clit. Circled it with the perfect amount of pressure.

Pepper’s hands braced against the wall. Her hips pushed back into the touch.

Natasha’s other hand came around to Pepper’s breast, pinching her nipple. Her mouth found Pepper’s neck, teeth scraping.

“Is this what you meant?” Natasha asked. “Back in the woods?”

“Yes.” Pepper ground down on Natasha’s penetrating fingers. “But you’re going to earn it first.”

“Tell me how.”

“On your knees.”

Natasha dropped with a double thud. Water pounded down on her from above. She looked up at Pepper, red hair plastered to her face, eyes bright.

“Spread my legs,” Pepper said.

Natasha’s hands pushed at Pepper’s thighs, opening her stance. The position made her muscles protest but she held it.

“Now make me come,” Pepper said. “Use that slutty tongue.”

Natasha surged forward. Her mouth sealed over Pepper’s cunt, tongue diving in. No teasing, no buildup. Just direct assault on her clit.

Pepper’s head fell back. One hand tangled in Natasha’s wet hair, holding her in place. The other braced against the wall.

Natasha worked with fury. Her tongue circled the clit, then flicked across it. Pleasure built rapidly in Pepper’s core, tight and hot. Her thighs trembled. Her breathing went ragged.

“Don’t stop,” she managed. “Right there. Don’t you dare stop.”

Natasha redoubled her efforts. Fingers joined her tongue, two sliding inside while her mouth stayed locked on the clit.

The dual sensation pushed Pepper over. Orgasm crashed through her—white-hot and devastating. Her knees nearly buckled. Only her grip on Natasha’s hair and the wall kept her upright.

Natasha worked her through it, easing off only when Pepper’s hips flinched from over-sensitivity.

When Pepper could breathe again, think again, she looked down. Natasha knelt in the spray, face tilted up, waiting.

“Good,” Pepper said. Voice rough. “Very good.”

She pulled Natasha up by her hair, crashed their mouths together. Tasted herself on Natasha’s tongue, swallowed the small sound she made.

When they broke apart, both breathing hard, Pepper smiled.

“Now let’s get you clean,” she said. “And then I’ll decide what to do with you next.”

Natasha’s answering smile was sharp and eager. “Yes, ma’am.”

The shower ran hot around them. Steam filled the bathroom. And outside, the forest stood quiet and indifferent, keeping its secrets.
