“Oh god. Oh fuck! Nat, I don’t think this is a good idea!”
“Just relax Bruce. We both know you’ve always wanted to do this” the redhead purred before wrapping her lip back around his cock, sucking it expertly making the scientist groan.
Bruce was aware of how much he had wanted to be in this position with Natasha, for so long. But every time she offered he turned her down. It was too dangerous. The other guy was always temperamental. Any increase in his heart rate could bring him out. It made getting excited risky, which made relationships complicated. Not even when he was with Monica did they get further than second base. He should’ve known Nat was up to something the moment she suggested a walk out into the canyon after a mission, away from civilization and other forms of life. They found a spot behind some rocks overlooking the desert and before he knew it she was on her knees in front of him fishing his penis out of his trousers. It only took a couple of kisses to subdue any resistance before he was letting her giving him a blowjob. And such a good blowjob. So long since he’d done this, it wasn’t long before his balls were begging for release.
But he could also feel the other guy drawn to the surface too. Nothing like sexual frustration to draw out the big guy. “Nat…it’s coming” he warned, his voice deepening as his eyes glowed green.
Natasha looked up from his lap, continuing to suck his cock to hide the smile. “Yes, that’s it” her other called, wrapping her tongue around his head to stimulate the scientist milking his dick. Nat plunged her mouth all the way down his cock, taking it into her throat as it throbbed painfully. She felt it pulse in her mouth as Banner dug his nails into the rock he was sitting on, the hard surface cracking beneath his fingers as his veins turned green. “Yes, bring us the big guy. Not puny Banner. We want the Hulk!”
While Nat would normally scold her other for such a statement, as she rather liked puny Banner a lot, on this particular occasion she was seeking the big guy to test her limits. Her symbiote friend had enhanced much of her abilities and skills lately, but she’d been curious to see if said enhancements could withstand the strain from their strongest avenger. She didn’t like using Bruce like this, but she figured bringing his alter out like this would be more humane than making his mad. And she’d been begging to have sex with him for a long time. Hopefully one day they’d find a way to do it.
For now, one simple blowjob was enough to give Banner some much needed stress relief as he ejaculated into her throat, while at the same time triggering his transformation which made his body grow tearing his clothes apart. Nat felt his penis expand in her mouth and quickly removed herself from his still dripping dick watching it grow to ten times its size right in front of her eyes. She’d only caught glimpses of the Hulk’s manhood during their time on the Avengers and it always left the Russian spy stunned. It also made her gulp down the last of Bruce’s sperm as she realized this was what she was attempting to take into her body today. “I hope you’re right about this” she whispered under her breath to her other.
“We are stronger now” it assured her. “Our body is stronger. Will adjust and adapt. We can take it.”
Natasha lifted her head and looked up at the Hulk, who now sat in Banner’s seat looking down at the small woman kneeling in front of him. “Hey big guy” she smiled warmly, hiding her trepidation as she reached out and put her palm on his penis. Unlike before where her hand could wrap around Banner, his cock was too big for both her hands to wrap around. She felt it throb against her skin, shivering in anticipation as her other hand unzipped her costume slowly. “Sun’s getting real low” she muttered under her breath before opening her uniform and pressing her chest against him.
Hulk watched as the Black Widow rubbed herself against his shaft, her breasts brushing his thick green skin as she wrapped her arms around him. He stared at her silently, breathing heavily as she peppered his cock with kisses. She couldn’t tell what he was thinking, if he liked what she was doing. She hoped so. She’d hate to be tossed into the canyon for underperforming. Her first sign that the Hulk was aroused was when his cock pulsated between her breasts and leaked precum over her hair. She looked up at him and bit her lip, rising to her feet and climbing out of her costume. “Here goes nothing” she whispered as she climbed up his knees onto his lap, hoisting herself up to position her pussy over his cock. She locked eyes with the Hulk, who gave a small smirk as he rubbed himself against her. She took hold of his dick to steady herself and sucked in a deep breath.
Either her symbiote would help her body adapt so it could insert a dick of this immense size, or the Hulk was about to rip her apart. With a little mental encouragement from her other Natasha Romanov muttered a prayer before lowering her hips down onto the erect organ waiting for her.
Nat couldn’t recall what the biggest thing she’d stuffed into her vagina was. But whatever it was, taking the Hulk’s cock dwarfed anything she might’ve come up with. The moment it pressed up against her entrance doubt seeped it. His tip was larger than a fist, a flat bulbous fist pushing against her undercarriage. She felt the big guys gaze upon her as she tried to lower herself down upon it, his hot breath blowing on her face as he waited in anticipation. Her symbiote helped her along by lubricating her entrance, which was pried open by two helpful tendrils which also aligned his cock properly. She pushed herself down and felt it begin to slide inside. There’s no way this will fit she thought.
“It will” her other promised, forcing her to keeping going and slide down the shaft. Nat grimaced as she felt her pussy stretch, attempting to accommodate it. It stretched as wide as it could, but it didn’t seem to be enough. But then her body slide further and Nat gasped, feeling the symbiote altering her body to expand further, stretching over the impossibly large dick. “Yebat!” Nat screamed, her foot slipping causing her to fall onto the Hulks lap, halfway down his shaft. She froze, eyes wide as she looked down and saw the large bulge in her stomach, felt his cock pressed against her cervix, her body stuffed with his penis.
Fuck, I’m alive.
“Told you” her other gloated.
Hulk grinned from ear to ear. This was the first time a puny mortal had been able to take his dick. He groaned in excitement as Natasha regained her balance and began tentatively lifting her hips up and down. Each time she slide down she moaned loudly, feeling him shift her insides as her body squeezed him. It was like the symbiotic made her flesh elastic. She ran her palm over her belly and felt the head moving inside her as it was pulled in and out. She leant against his muscular chest, riding him slowly finding a steady pace that didn’t feel like she might tear apart. But after a minute the Hulk got impatient. Before she could say anything his palm fell onto her lower back and was pushing her further. She cried out as his dick penetrated her uterus, sheathing inside it making her gasp and shudder. Her body squeezed him tighter, adjusting to the additional intrusion. She couldn’t be sure if she just climaxed or was mistaking it for agony. Maybe her symbiote was simply switching off her pain receptors. This is too intense. “Hey big guy. Could we maybe slow down a little?” She asked.
“No” he grunted, too eager to fuck as he thrust his dick into her cunt, enjoying the way she massaged him too much.
She moaned and gasped and whimpered as he pressed her to his chest, forcing her to bounce on his cock, her legs hooked over his swollen balls. She felt them throb and she realized what was coming, her skin turning pale. “Wait! Wait, I don’t think…Bruce! Hulk! Please, don’t…”
Too late. The hulk slammed her onto his lap and growled, ejaculating into her tight and sterile womb. Natasha’s eyes widened as she felt his sperm shoot inside her body like a geyser, her mouth falling open as her mouth failed her. The symbiote was quick to react, making her body form a tight seal to catch the radioactive semen. She shivered as her belly expanded, cum leaking from her pussy dripping onto the rocks. It was more than any man could’ve expressed, enough to make the Russian spy appear nine months pregnant by the time she was lifted off his lap so his cock could exit. Instantly her elastic pussy snapped back to normal, holding as much of his cum inside her as she could.
Nat looked down at her swollen belly and instantly felt sick, slumping against Hulks chest and immediately forcing her insides to force the cum out. She wasn’t worried about getting pregnant, that was impossible, but it was too much even with an alien organism bonded to her. Her other helped her expel the cum, after taking a moment to feed off the radiation through her uterus, draining her insides until she was panting heavily against the big green Goliath. “Satisfied” it asked her.
“Okay, point proven” Nat mumbled, feeling very drained as she shifted uncomfortably on Hulks lap. She looked up at the big green guy, patting his chest affectionately. “Good job. That was…an experience. We should head back to the Chimera” she suggested.
The hulk looked down at her as she tried to climb off his lap. With a low growl he wrapped his hand around her waist and lifted her off her feet, holding her in front of him. She clung to his fingers grateful for the loft, happy to be carried back home. But when his other hand came up and tilted her body backwards, she looked down and saw the throbbing cock still erect and primed. She looked up and gulped as he fixed his intense gaze on her lower hand, his other hand spreading her ass cheeks with two fingers. Oh no! She panicked.
“We’ll survive” her other promised, already adjusting her body in preparation for what they realized was coming.
“Hulk ready” the big guy grinned, plunging his dick into Natasha’s ass as she screamed from the penetration, her anus stretching beyond its limits as he pulled her down all the way to the hilt. “HULK SMASH!” He bellows as his cock rearranged her insides and thrust into her tight body.
Nat’s eyes rolled into her skull as she blacked out, her symbiote taking over to submit her body to the Hulks sexual rampage.
She had no idea how much time passed after that. She would periodically fade in and out of consciousness as she was fucked relentlessly by the green giant, her body little more than a cock sleeve for him as he pumped his dick in and out of her. She heard a female voice, possibly her own, screaming between moans of pleasure. She heard another voice, her other, echoing hers inside her head. Or was it her voice in her head and her other screaming for more. Her eyes fell open at one point to see the horizon of the desert before them, upside down from her point of view as her head fell back, her arms and legs folded limply towards the ground. She felt the hulk’s hands wrapped around her, pinning her arms to her sides, sliding her onto his cock like a rag-doll, a sex toy. She felt her stomach bulge from every penetration, her insides expanding to fit him, her organs forced out of the way to make room for his penis. Her breasts bounced on her chest, her nipples pointed at the sky. Somewhere in her delirium she glimpsed how she looked, though whose eyes she looked through escaped her. She saw herself, in the grasp of the big guy, her skin covered in the black and red ooze of the symbiote as it stretched around his cock. She looked up and found the Hulk grinning and grunting, repeatedly muttering “Hulk Smash” as he pounded her. She certainly felt smashed as another orgasm rippled through her body lulling her back into unconsciousness, replaced by another letting her pass out so it could enjoy the Hulk for itself.
Eventually it call came to a merciful end as the Hulk reached the climax, his cock throbbing as he pounded Nat with greater force, his grunts getting erratic as she found herself bouncing up and down so fast she was sure to get whiplash. Her consciousness snapped back in time to feel the Hulks final thrust as he buried himself all the way inside of her, his oversized balls unleashing their contents into her clenching ass filling her insides. She screamed as it pumped into her stomach, her belly becoming bloated until Hulk’s fingers tightened p, threatening to crush her as the Hulk lost control. She felt more of his cum spill into her, her eyes rolling into her skull as she coughed up his semen from her mouth and nose, her insides flooded with his sperm. Her body stiffened around his cock, squeezing his cum out until he staggered backwards limply. She hung from his dick a moment before it deflated, slipping out of her gaping anus as he dropped her to the ground. She collapsed limply sprawled over the floor as his cock splurged more cum over her, drenching her in semen while she choked and leaked more from her orifices. She lost consciousness again just before a drained Hulk slumped against the rocks and fell asleep, reverting back into Bruce Banner.
She had no way of knowing how long it took for her to regain consciousness. When she did, had to gag and vomit up more of his cum to make herself breathe again. She opened her eyes and stared up at the evening sky as she heaved in one painful breath after the next. “Now that was a good fuck” her other praised, the symbiote buzzing from the radiation it fed off from his sperm.
Nat wasn’t sure she could say the same as her whole body ached. She could feel her anus was still gaping wide as it leaked more substance, burning from the friction. Her pussy hurt worse, her belly swollen and bloated, her internal organs struggling to maintain her abused body. She could feel her symbiote adjusting her insides back to normal, an agonizing process which it bulled into a constant ache while she fought to breathe. She swallowed a large gulp of cum to clear her airway and gasped, her throat raw and sensitive. When she tried to talk it hurt, so she didn’t. She sluggishly raised her head to look down at her body, covered and stained with cum and sweat. She was a mess, worse than a whore after a gang bang.
She turned her head to the side and found Banner passed out and naked a few feet away. She felt bad about dragging him into this, and still hoped one day they’ll find a way to let them fuck without involving the other guy. But right now she hoped she recovered before he did so she could clean up and be gone before he woke up, praying he won’t remember any of this. She didn’t want to face the awkward conversation of why she brought him out here.
She hoped the Hulk enjoyed her little experiment, because while they’ve officially proven she can indeed survive having sex with the hulk now, she had no intention of going through that experience again.
Her symbiote, however, made no such declarations.
