She woke to the weight of her own body, pressed into something soft—too soft, the mattress giving under her like a cloud. The hotel room smelled different now. Cleaner. Sharper. That metallic tang underneath the perfume.
She tried to lift her hand to rub her eyes. Her wrist didn't move. She tried the other. Same thing. Her ankles, too—spread wide, straps biting into her skin. Panic flickered through the fog in her head, quick and electric. She was sprawled across the bed, arms and legs stretched to the four corners, completely open.
"Henry?" Her voice came out cracked. Thick. Like she hadn't spoken in hours.
Movement at the edge of the lamplight. A chair creaked.
"There she is."
Henry stood, stretching like he'd been waiting a while. He crossed the room in three easy strides and stood at the foot of the bed, looking down at her stretched body with open satisfaction.
"What—" She licked her lips. Tasted nothing but dry. "What is this? Henry, untie me."
"You said you wanted a surprise." He was calm. Easy. The same voice he used when he told her to clean the kitchen. "A few weeks ago. After the shake. You were half-asleep, but you said it. 'I want you to surprise me. Fill me when I don't expect it.'"
She searched her memory. Came up with nothing. A hot flush of shame and something else—something that tightened low in her belly—pulsed through her. "I don't—"
"You don't remember. I know." He moved to the side, and she heard the scrape of metal against the floor. A tank. Tall. Shiny. Party-size, the kind they rented for kids' birthday parties, except this one had a regulator attached, a hose coiled around the neck like a sleeping snake. "But I do."
Her eyes traced the hose. Followed it to the Y-splitter connector. Two ends. Her mouth went dry.
"Henry. Wait."
"Shh." He crouched beside the bed, his hand finding her face, thumb brushing her cheek. "You're going to love it. Trust me."
She should say no. Her brain was catching up, slotting pieces together—the two hoses, the tank, her bound body—and every instinct said this was too much. But her cunt was already clenching, a warm, wet pulse that betrayed everything her mouth was about to say.
He saw it. Of course he saw it. His smile deepened, and he leaned in, pressing a kiss to her forehead.
"That's my girl."
He rolled her onto her stomach. The straps allowed just enough give for the movement, the mattress sighing under her weight. She felt his hands on her hips, then lower, parting her thighs from behind.
"You've been wearing it all night," he said. "Like a good girl."
She'd forgotten. The buttplug—the one with the port in the base. He'd talked her into it before bed, calling it kinky, promising he'd take it out in the morning. She'd fallen asleep with it inside her, and it had stayed, a faint pressure she'd stopped noticing.
Until now.
His fingers found the plug. Teased it. Pulled it out an inch and pushed it back in, slow, deliberate, and she gasped into the mattress. "I need you ready," he murmured. "Open."
He pulled it free completely, and she felt the sudden emptiness, the raw, unsheathed sensation of being hollow. Then something else pressed against her—cooler than the plug, narrower. Silicone. The hose.
He worked it in slowly, twisting it through the port of the plug until it seated deep inside her, the base of the plug locking it in place. She felt it coil inside her rectum, a foreign presence, and she whimpered against the sheets.
"Good. That's one."
He rolled her onto her back again. Her legs were still spread, the hose trailing from her ass across the sheets, connecting her to the tank like an umbilical cord. Her eyes followed it to the Y-splitter, then to the second hose. Coiled. Waiting.
He picked it up.
"Henry." Her voice cracked. "Please. Not my mouth."
"You said surprise." He was calm. Certain. The hose in his hand, the other end already connected to the tank. "This is it."
She shook her head, but her body was betraying her—her nipples hard, her hips shifting, the slick heat between her thighs undeniable. He saw. He always saw.
"Open."
She kept her mouth shut. Pressed her lips together. Shook her head again.
He waited. Didn't force it. Just stood there, the hose in his hand, watching her with that patience she'd come to know—the patience of someone who knew he'd win because she wanted to lose.
The seconds stretched. The hiss of the AC. The beat of her heart.
She opened her mouth.
The hose was cool against her tongue. Silicone, faintly slick. He pushed it in until she felt it at the back of her throat, and she gagged, tears springing to her eyes. He held it there until she adjusted, then taped it in place—a strip across her mouth, sealing her lips around the tube.
She couldn't close her mouth. Couldn't push it out. The tape held her open, held her receiving, and the hose led straight to the tank.
Henry stepped back. Admired his work.
Then he walked to the corner of the room and picked up the camera.
She watched him set up the tripod. Frame the shot. Check the lighting, adjust the angle until she was perfectly centered—spread, bound, hosed at both ends, her belly the only empty thing left in the frame.
"For the fans," he said. "They're going to love this."
She tried to speak, but all that came out was a muffled, vowel-thick sound around the hose. Her eyes said everything her mouth couldn't—fear, arousal, disbelief, hunger—and he read all of it as he pressed the record button.
The red light blinked.
He walked to the tank. Crouched beside it. His hand found the valve.
She watched his fingers wrap around the knob. Watched his eyes find hers, holding them through the distance between them. He smiled—that slow, knowing smile—and she felt her cunt clench, her body betraying her one last time, telling him what her mouth couldn't: yes.
He turned the valve.
The hiss was soft at first. Almost gentle. The sound of a balloon being filled, a whisper of gas moving through the hose. She felt it in her ass first—a cool, expanding pressure, like she was being inflated from the inside out. It spread through her rectum, her colon, pushing outward, filling spaces she didn't know she had.
Then she felt it in her throat.
The helium moved down her esophagus, a distinct sensation of something going *down*, reaching her stomach, pooling there. The two pressures met in the middle of her belly, a collision of cold and expansion, and she felt her abdomen begin to rise.
It was slow. Inevitable. Her belly, already slightly heavy from the previous night's batter, began to stretch outward. She watched it from above, her eyes wide, her bound hands useless at her sides. The skin tightened. The curve became more pronounced.
Henry crouched beside her, his hand finding the dome of her swelling stomach. He pressed lightly, feeling the pressure inside, and she whimpered around the hose.
"There it is," he said. "There she is."
The hiss continued. The gas flowed. Her belly rose higher, rounder, smoothing out the softness of her post-pregnancy belly into a tight, gleaming sphere. She could feel the helium filling her, lighter than air but building pressure, expanding her from the inside until she was taut and full and still growing.
The stretch marks on her flanks began to tingle, the skin pulled thin and bright. She remembered the twins, the last weeks of that pregnancy, the way her belly had felt before they came—tight, heavy, impossible. This was different. This was pure cavity, pure expansion, no baby pressing against her ribs, just gas filling every corner of her gut until she was nothing but belly, nothing but the curve of her own fullness.
Her muffled moan escaped through the tape. She couldn't stop it. The sensation was too much—the pressure, the stretch, the helplessness of her own body inflating beneath her. Her cunt was soaked, pulsing, and she was ashamed and aroused and desperate for him to touch her there, to give her something to clench against.
He didn't. Not yet.
He just watched. His hand on her belly, feeling it grow under his palm, the skin warm and tight and rising. His eyes on hers, reading every flicker of fear and need.
She felt herself rounding out. Becoming a sphere. The hiss was steady, the tank's pressure constant, and her belly pushed against her ribs, against her hips, spreading wider, rising higher, until she was nothing but the curve of her own belly, suspended in the lamplight, her limbs forgotten, her voice stolen, her body a perfect, swelling globe.
The lamp caught the high point of her stomach, casting a single gleam on the smooth, tight skin. She watched it rise. Watched Henry watch her rise. The camera's red eye blinked between them, recording every inch of her growth, freezing the moment for the followers who would watch it later, would see her become what she was always meant to be.
Full. Stretched. Held open and filled.
And still the hiss continued, still the gas flowed, still her belly grew, rounding out beneath the lamplight like a moon rising over the bed.
She saw it before she felt it—the way his boxers strained, the fabric tenting forward, a dark spot of moisture spreading at the tip. He wasn't hiding it. He wanted her to see.
Henry's hand slid down his own body, slow, deliberate, making sure she watched. He hooked his thumb under the waistband and pulled. His cock sprang free, already hard, the head slick and dark against the lamplight. He wrapped his fingers around the shaft, gave it a single, lazy stroke, and her mouth went dry around the hose.
He stepped closer. The bed dipped under his weight as he climbed on, straddling her, his knees on either side of her hips. He was above her now, his cock hanging inches from her face, and she could smell him—salt and skin and something muskier underneath.
He didn't put it in her mouth. Instead, he dragged the head across her cheek, leaving a wet trail. Then across her lips, smearing the tape. Then down her chin, along the column of her throat, between her breasts, over the tight curve of her belly.
The helium made her skin taut, stretched thin and gleaming. She felt his cock press into the dome of her stomach, and the give was different now—less flesh, more resistance. The head of him left a shallow indent as he dragged it across the surface, and she felt it from the inside, the pressure of his weight on her gas-filled cavity, a counterpoint to the steady hiss of the tank.
He circled her navel with the tip of his cock. Then pressed harder, letting her feel the shape of him against the full curve of her, and she let out a muffled sound—half whimper, half moan—and her hips shifted, searching for contact she couldn't reach.
"Look at you," he said. His voice was rough. "Look at how full you are. And you're still growing."
He was. Her belly was higher than it had been when she'd first opened her eyes, rounding out toward the size of her twin pregnancy, the skin pulled smooth and bright. The stretch marks on her flanks were fading into the curve, disappearing into the sphere, and she could feel the helium pressing against her diaphragm, making every breath shallow and precious.
Henry shifted, moving behind her. The mattress dipped as he positioned himself between her spread thighs, his cock sliding along the inside of her leg, leaving a smear of moisture on her skin. She was soaked. She could feel the wetness cooling against the air-conditioned air, could feel her own need pulsing between her thighs, shameless and undeniable.
He didn't enter her yet. He leaned forward instead, his chest pressing against the broad curve of her belly, his mouth finding her ear. "You're going to inflate for as long as I fuck you," he said. "Until I come. That's how long the gas runs. You understand?"
She tried to nod. The straps limited the movement. Her eyes found his, wide and wet, and she made a sound around the hose that could have been yes or no or please.
He smiled. Then his hand went to the nightstand beside the bed, and he pulled open the drawer.
She saw the remote before he lifted it. Black. Slim. Three buttons—a power symbol, a plus, a minus. The same remote from Chapter 3, the one he'd used while she was strapped to the padded chair, the one that had made her see stars while her belly was full of cream and soda and his cock.
Her eyes went wide. She shook her head—a tiny, desperate motion—but her cunt clenched at the memory, and he saw it, and he smiled wider.
"You remember this," he said. "Good."
His thumb found the power button. Pressed it. A tiny blue light blinked on the remote, and through the fullness in her ass, through the steady pressure of the helium filling her colon, she felt the plug begin to hum.
It started low. A vibration she could barely distinguish from the sensation of being filled, a faint buzz at the edge of her awareness. Then he pressed the plus button once, and the vibration deepened, spreading through her rectum, radiating into her core. Her hips jerked. The straps bit into her wrists and ankles. A muffled cry escaped through the tape.
The vibrator was inside her, pressed against her walls, and the helium was still flowing, and her belly was still rising, and she could feel both sensations at once—the fullness of the gas and the pulse of the vibration, layered together like a chord struck inside her body.
Henry watched her face. Watched her eyes go glassy. Watched her mouth stretch around the hose. He pressed the plus button again, and the vibration kicked higher, harder, and her whole body trembled.
Then he reached into the same drawer and pulled out two pills.
Small. Red. Familiar—though she'd never seen them in person. They sat in his palm like two drops of blood, and she knew them the way any woman who'd been with men who had something to prove knew them. A delayer. A quantity increaser. The kind of pills men swallowed when they wanted to fuck longer, harder, and fill you fuller than you'd ever been filled.
Her breath caught. Her cunt clenched. Terror and arousal twisted together in her chest, and she didn't know which was winning.
He held her gaze as he tossed both pills into his mouth. Swallowed dry. The motion of his throat was visible in the dim light, and she watched him the whole time, unable to look away, her body already braced for what was coming.
"Margin for error," he said. "I want to last. I want to fill you." He leaned over her, his face inches from hers. "And I want you to feel every second of it."
He shifted his weight, settling between her spread thighs. His cock brushed against her wetness—once, twice, teasing—and she bucked against the straps, trying to push into him, trying to pull him in. The vibrator was still humming inside her, a constant pulse against her inner walls, and the helium was still flowing, her belly rising another inch, another curve, rounding toward the size of her twin pregnancy.
He positioned himself at her entrance. She felt the head of him press against her—hot, slick, swollen—and she stopped breathing.
"One more thing," he said. He reached behind her, to the valve on the tank. Turned it a quarter turn. The hiss deepened. The flow increased. Her belly pushed outward faster, the skin tightening, the pressure building, and she whimpered, the sound swallowed by the hose and the tape and the constant flow of gas filling her gut.
"I want you bigger," he said. "I want you full."
And then he pushed inside her.
The sensation was different than she remembered. Tighter. Fuller. The helium had expanded her abdominal cavity, pushing her organs upward, compressing her pelvic floor, making the channel of her cunt narrower, more resistant. She felt every inch of him as he slid in—the stretch, the burn, the impossible fullness of being filled from both ends at once. His cock inside her. The hose in her ass, pumping gas into her colon. The vibrator pulsing between them. Her belly rising against his chest as he bottomed out, buried to the hilt in her.
She came.
It was instant, involuntary, a clench that ripped through her without warning, her cunt gripping him, her body spasming against the straps. He waited through it, holding still, letting her ride the wave of the first orgasm, and when she collapsed back against the mattress, trembling and gasping around the hose, he began to move.
Slow. Deep. Each thrust a push into the tight wet heat of her, the vibration of the plug humming through her core, the helium hissing, her belly growing. She could feel it against his stomach, the curve of her pressing into him with every forward stroke. He was fucking her, and she was expanding, and the two sensations merged into something singular—filling and being filled, stretching and being stretched, the rhythm of his body against the constant flow of gas.
He sped up. The mattress creaked. The camera's red eye blinked, recording every moment, every angle, every inch of her growth. She didn't care. She couldn't care. The helium was pushing her past limits she hadn't known she had, her belly rising past the size of her twin pregnancy, growing into new territory, new curves, new stretch marks glowing under the lamplight.
She could feel the weight of her own belly now. The heft. The pressure. It rested against her thighs, against her hips, against his torso as he drove into her. He reached down, pressing his hand against the underside of the globe, feeling her stretch from the inside, and the pressure of his palm against her full, taut belly sent another shockwave through her.
She came again. Harder this time, her body arching against the straps, a long muffled scream tearing through the tape. Her cunt clenched around him, pulsed, fluttered, and he groaned, slowing his rhythm but not stopping, riding her through the orgasm.
"That's it," he said. "That's my girl. Keep going. Keep growing."
The tank hissed. The vibrator hummed. Her belly rose. The drum of his cock inside her, the stretch of the gas expanding her cavity, the blue light of the remote blinking steady—she was drowning in sensation, every nerve ending firing at once, every part of her full, stretched, claimed.
He leaned forward, his mouth against her ear, his breath hot and uneven. "I'm close," he said. "I'm going to fill you. I'm going to fill you until you can't take any more. And still the gas is going to keep coming. Understand?"
She nodded. The motion was weak, her head barely lifting off the pillow, but she nodded. Yes. Please. Don't stop. Fill me. Fill me.
He drove into her harder. Faster. The rhythm broke, became urgent, desperate, and she felt him swell inside her, felt the first hot pulse of his release, and he came—a torrent of warmth flooding into her, hot and thick and impossibly full, filling the space the helium had left in her pelvic cavity, filling her from the inside until she was nothing but contents, nothing but fullness, nothing but the curve of her own body stretched tight around everything he had given her.
He kept moving. Kept thrusting, slower now, riding his own climax, and the tank was still hissing, still filling her, and her belly was still rising, pushing past her ribs, rounding into a sphere so vast that she could barely see her own bound arms, could barely see the edges of her own body in the lamplight.
She was as big as the last weeks of her twin pregnancy. Maybe bigger. The skin was stretched so thin she could see the blue of her veins beneath the surface, could feel the pressure pressing against everything inside her—her lungs, her stomach, her heart beating against the expanse of her own gut.
She was full. She was stretched. She was held open and filled from both ends.
And she had never felt more complete.
Henry pulled out slowly. His cum leaked from her, a warm trickle against the sheets, but she barely felt it—her body was too full of gas, too stretched and taut, to track a single spill. He collapsed beside her, his hand landing on the dome of her belly, pressing lightly, feeling the pressure hiss back against his palm.
The camera kept recording. The lamp kept burning. The helium kept flowing.
Her belly rose one more inch, rounding out beneath the lamplight, and she watched it rise, watched herself become something larger than she had ever been, watched the sphere of her own body fill the frame.
She was everything. Full and held and his.
