She tried not to sound too eager about that fact, her breathing just as intensive as her boyfriend's was. Focusing on the point of contact between them, Melanie began pushing her cockhead against Alex's asshole; it was going to be a tight fit no matter what, but hopefully her preparations helped in the matter. Alex immediately moved away from her, his body instinctively dipping forward as he tried to escape the girthy invader. Seeking to rectify this behavior, Melanie took her hand off her shaft and roughly grabbed his hips, coaxing him back towards her until they were touching again. Now that he was in his proper place once more she continued her forward march, squishing her fat tip against his rear.

"Don't worry baby, this is gonna feel good." Melanie comforted him as she nuzzled her cockhead harder against him, "You can trust me

"I do Melanie, it's just a lot!"

"I know Alex, just bear with it. Try and relax for me."

Easier said than done! Alex could feel the tip of her tip begin to barge into his asshole, and it made him already feel more stretched than when she'd been fingering him! He couldn't help but grunt and grit his teeth, every ounce of reason in his body fighting with him, urging him to make a run for it - but he wouldn't. He couldn't! It was too late now, the cards had been dealt and he had played on them. What willpower he did have left kept him glued in place as he was pulled apart more and more, Melanie going as slow as she'd promised she would, her massive helmet still not fully inside of him.

To Alex it felt like the large end of a baseball bat was being inserted into his rectum, Melanie's cock was so incredibly enormous. He was almost afraid he'd tear from it! But he trusted her, and - as he'd considered in the past - if other guys could take her he could too! Trying to do as she said, he did his best to loosen his muscles and not clench down around her bulbous battering ram, pretending for a moment that he was doing something much less sexy; this helped him a bit, especially as he heard Melanie moan as she sank more of her cockhead into him. He almost had it all in, even if it was just the beginning of what the rather-delicate girl possessed!

Melanie was on another planet.

She almost felt like pinching herself to make sure this wasn't all a dream! Alex was even tighter than she'd imagined, than she'd fantasized about for so many years, and once again the fact that it was him made the whole thing even better. Moaning as her cockhead buried itself all the way into his once-taut-rim, she stared at his stretch hole with lurid desire, wanting to plow him as hard and fast as she could! Acting the part of the good girlfriend instead, she paused her fucking, allowing him to get used to the feeling of fullness that he was undoubtedly dealing with at the moment. God he felt good!

"You okay baby? It's not too much is it?"

"I-I'm fine," Alex grunted, trying to sound strong, "I can, can h-handle it!"

"Just tell me if it's too much!" Melanie reassured him again, "We can stop whenever you want!"

That was hard to say - she didn't want to stop ever!

"You're good Mel, I can do this!"

Purring at his display of courage, Melanie took a deep breath before continuing. Placing her other hand on his hip so that she had both firmly held, she inched forward, sliding the start of her venous, bitch-breaking shaft into his clenching depths; it was like trying to fit a loaf of bread into a Dixie cup, but she persisted regardless! She learned forward as she pumped gingerly into him, her constantly-leaking cum greasing her cock and his hole, the lube next to her unneeded. After she managed to embed another section of her shockingly stiff spear she pulled back, sliding her member back and forth, fucking Alex with a mere fraction of what she had to offer, moaning at how tightly he gripped her pole.

Not able to do much but rest on his hands and knees and bare it, Alex did everything he could to find pleasure in his girlfriend's actions, something that was becoming surprisingly easier to do the more she fucked him. Like her fingers had but much more roughly the sides of her stupendous shaft ground into his pleasure center as she pumped it steadily into him, nearly flattening it painfully in the process but stimulating it just enough to still feel good. Alex tried to focus on that and the way it made his cock get hit with jolts of ecstasy, his own member dripping precum; he never thought that getting fucked would make him feel like this! It still wasn't his favorite thing he'd ever experienced, but it was getting harder and harder to deny that he liked it.

The feeling of fullness was another aspect of being on the receiving end he had to wrestle with. It was uncomfortable how packed his bowels were, a strange sensation he had trouble coming to terms with. If he already felt this with what had to be less than half of Melanie's cock inside of him, how would it be when she was using all of it!? Alex couldn't help but moan as she pistoned to him, his body beginning to rock back and forth under her steady thrusts, his hands and knees sliding across the towels and leftover refuse. Sweat drenched his form from the effort it took to simply take her, his muscles straining and flexing once more, giving her a great view to ogle from behind him.

And what a view it was!

"Fuck you're so tight Alex!" Melanie gasped, not holding back her innermost thoughts anymore, "and you look so fucking sexy taking my cock!"

Sexy barely began to describe how good he looked at that moment! His asshole was gaped around her ramrod, stretched to sheer whiteness, pulsating in time with her movements. His ass constantly flexed against her arms and shaft like he was twerking for her enjoyment, the rotund, firm cheeks bouncing rapidly due to her quickening-thrusts. His torso and arms were magnificent and huge, sheening with moisture, glowing under the overhead lights. Fuck, she just wanted to ravage him! Growling, she lost another bit of self-restraint and picked up more speed, shoveling her cock halfway into him before pulling it out, her whole body jerking with her driving lust.

Every feature of her figure jiggled and jostled with her movements. Melanie's breasts flopped up and down on her chest, slapping loudly against her own skin. Her hair swayed to and fro, smacking off her back and shoulders, wet and heavy with her cum. And her balls swung like a pendulum, the sperm-stuffed grapefruits bouncing off her thighs and the bottom of her pert ass, not yet close enough to beat into Alex. She held Alex's wide hips tighter, her fingers denting his flesh as she plowed into him, her eyes wide with unbridled lust, her mouth hanging open with drool dripping from her lips; she looked like a woman possessed, one whose singular goal in life was to reshape her boyfriend's insides to better fit her awesome appendage.

And Alex was certainly feeling the carnality driving her every action!

He was panting loudly, his own eyes closed and his tongue slipping from his lips. Body wrenching back and forth under Melanie's forceful ministrations, he was helpless, unable to do anything else but try and survive! His pleasure increased with each passing moment, his girlfriend's cock touching more and more places inside of him he never knew existed, sending shockwaves of euphoria coursing through him. Package flopping around wildly, Alex wished that he could at least jerk himself off, his hands too busy keeping himself aloft to do so, his member ignored by the much grander one above it. Looking down at his torso, peering between his heaving pecs, his eyes bulged in their sockets at how much cock Melanie had outside of him still, her enormous cum factories oscillating violently under her monster - and that wasn't all he saw either!

"Fuuuuck! Melanie!"

His exclamation was a mixed one, both from rapture and horror. Alex's normally muscled, somewhat rounded stomach had taken on a different shape, one alien to him; there was a bulge denting the skin above his groin, one that had a specific shape he was becoming intimately familiar with. Melanie's cock, in all its oversized glory, was tenting his flesh, needing to make extra room inside of him just to fit! He could see the path it took through his guts perfectly, the outline of her mushroom-shaped glans leading the charge, sliding back when she did before barreling back through him. It was enough to almost make him pass out from shock, hardly able to even fathom the sight! What the fuck was she doing to him!?

"That's right baby, fucking take it," Melanie snarled, revealing the personality she'd hidden from him, the one that only came out in the throes of coitus, "take my big fucking cock!"

It wasn't like Melanie wanted to be vicious or forceful, but it wasn't something she could control when she was fucking someone; her libido was as massive as her cock was, and it had a tendency to take the reigns in times like this. Due to her size of her gigantic member she needed as much stimulation as she could just to get off and this usually came in the form of rough, violent sex. That was why she got so many noise complaints from the neighbors, why the walls around her bed were full of dents and cracks, and why men who left her bedroom did so with a limp in their step! She became an animal, one who sought nothing but pleasure from her partners.

Almost like the thoughts of what she was capable of were spurring her on, Melanie began fucking Alex even more ferociously, battering at his reddened, sore asshole with renewed fervor. Most of her cock was inside of him now, her crotch separated from his ass by less than half a foot of girthy shaft, her balls finally making contact with his genitals; each time she thrusted into him they would swing swiftly and collide with his much smaller pair, squishing his cock into his stomach. Her ruts picked up more and more speed, her cock swelling as larger and larger gouts of seed pushed its way through her cum tube, steadily filling Alex with her gooey progeny, cupfuls leaking out of his ass around her shaft and splashing onto her groin.

Now Alex really knew what it meant to hold on for dear life!

His eyes were even huger, still focusing on the same area of his stomach - though it was getting harder to maintain his vision as his body jerked back and forth under Melanie's powerful pistons. He could see her cock tunnel deeper through his guts, pushing his other organs out of the way to make the necessary space it needed, the bulge nearly at his chest; this was made even more difficult to watch as he winced every time her sagging, elephantine scrotum made contact with his own, her giant globes bullying his drained-walnuts again and again. Panting, moaning, crying out in pain, Alex was practically feeling the entire spectrum of emotions at once, each different sensation fighting with each other as his brain tried to make sense of all the different forms of stimulation bearing down on him.

First and foremost was how fucking stretched he was. Alex could feel every inch, every bloated blood vessel, every gnarled ridge and knotted crest of his girlfriend's cock with such clarity he could have drawn a picture of it without having to see it. The different parts of her member, from her flared, wide glans to her swollen urethra, pressed into different areas of his depths all at once, punishing his prostrate in an admittedly pleasant manner, and altering the rest of his insides at the same time, gouging him out like it was trying to come out of his mouth. With every powerful jackhammer it was like she was finding new ways to distend his stomach, crown cock darting around inside of him, punching at different sections of his figure.

And then there was how completely and utterly full he felt; he was right, the more of her member Melanie mercilessly thundered into him the greater the feeling of being crammed to the brim became. It was like she actively creating more expanses for her to fuck into that weren't there before, turning him into a living plaything for her to enjoy and use up. Not only was her colossus keeping him stuffed, her cum was doing its own share of the work in doing so as well. Alex thought he could hear the liquid virility she'd packed into him slosh with every thrust, like he'd drank too much beer after a night out. It was hot and dense, weighing heavily in his bowels, pushed and swirled around as she ravenously mixed up his guts. This was all new to him - new and amazing.

"Mel- Mel, I think I'm, I-" Alex panted and gasped, trying to say something, anything at all, "I'm gonna...!"

Right as he was about to complete his utterance, something he'd never imagined was possible happened. Melanie hilted. Melanie hilted inside of him. Despite everything he knew, everything he was sure was feasible, his girlfriend managed to bury every single inch of her fantastical, unreal cock into his asshole, her crotch meeting his backdoor with a wet smack. She stopped moving when it happened, sucking in a loud, ragged breath of air as she did, her hands tightening against his hips like she was trying to crush his body like a soda can. They stayed like this, shaking, entangled in connected rapture, until Alex suddenly howled.

"FUCK!"

The moment he screamed his arms gave out and he fell face-first into the bed, held up by nothing more than Melanie's strength; her strength and her cock. Simultaneously his dick straightened and his balls pulled up against Melanie's enormous, all-encompassing pair. He was cumming. Still half-yelling, Alex's body pushed back against Melanie's - an instinctive action he had no control over. His cock throbbed as he orgasmed harder than he ever had before - more powerfully than he had when fucking her - ropes of cum shooting from his pulsating tip. Cords of all the remaining semen in his testicles fired onto his chest, stomach and the bulge of Melanie's member distending them, her enormous glans splitting his pecs like a pair of breasts, covering himself in his own gooey excretions, seemingly unending as he twitched and moaned from his first ever cock-induced climax.

Melanie could feel it all. She could feel his balls spasm against her immense sack, paling in comparison to her obese orbs. She could feel his asshole clench so tightly around the base of her mighty trunk it was like a vice trying to cut it from her body. She could feel his cock bounce and lurch against the outline of her member in his torso. Alex was hers now, fully and truly, nothing else left to drive a potential wedge in their relationship. He had cum from her fucking him, and that was all it took to unite them as one. It made her happy and, more importantly, hornier to see it happen, her gaze full of joy and carnal desire as she watched him quiver limply on the bed before her, lost in the best orgasm of his life. It was perfect.

As Alex rode out his mind-numbing orgasm, Melanie shifted her position. Rising up so that she was nearly standing over him, her cock pulling out but not leaving his battered backdoor, she leaned forward, sliding her hands up his back as she did. Grabbing onto his shoulder, her pliable tits squishing around his spine, Melanie put her face as close to Alex's head as she could, her body stretched as far as it could. Letting her warm breath bathe his neck, she kissed his sweat-moistened skin several times, reminding him she was still here, that she still cared for him.

"Did you like that baby? Are you okay?" She whispered into his ear, "Did you like cumming on my big fucking cock?"

His eyes rolled around in his skull as he mumbled incoherently, wearing a sloppy, sagging grin of contentment; saliva dripped off his extended tongue onto the bed below him, his nostrils flaring as he tried to inhale enough oxygen to stay conscious. He was so cute! Melanie stroked his sweaty ginger locks, admiring his blissed-out expression, momentarily broken out of her lurid fury by her admiration for her boyfriend - but only momentarily! While she was staring at him lovingly, his asshole clenched around her shaft, a moan immediately escaping his lips, a tremble running through his body. Her lust was reignited once more.

"Good baby, I'm glad, because there's a lot more where that came!"

All bets were off.

Hunching her back and holding his shoulders tightly, Melanie slammed her monstrosity to its trunk-like base into him, her wrecking balls plowing into Alex's junk. He howled again, his body stiffening against hers, instinctively preparing itself for further ruining, something Melanie was more than happy to take advantage of! She repeated her brutal action again and again, picking up speed as she shoveled her cock in and out of her boyfriend as much as she could, her hips slapping into his ass loudly. Snarling, her visage contorted into something inhuman as she fucked him once more, roughly beating against his asshole in a pile of mush.

"Oh fuck I can't wait to do this to you every day!" She exclaimed, knowing that Alex wasn't cognizant enough to remember anything she said, "When we live together I'm gonna fuck you like this all the time! Wake you up with my cock in your ass, fucking you in the shower and before bed! I need a lot of orgasms to be satisfied baby!"

Her body oscillated violently as she whipped herself into a frenzy,

"Of course you'll be fucking me too. You're so good with that big cock! All our neighbors are gonna know your name from how loud I scream it!"

Melanie's brain was filled with images of them living together. Going on cute dates at fancy restaurants, attending sports games, and having picnics at the park. Waking up together, cuddling, kissing before things got hot and heavy. Having sex in every room in their house, on every surface, against the floors and walls. Alex coming home from work or the gym, sweaty and hot, turning her on just by existing. Pouncing on him as soon as he walked in the door, throwing herself at him, wrapping her limbs around him before he could even get changed. It would be perfect, the life she'd always wanted - that she'd always wanted with him!

Spurred on by these fantasies, she went into overdrive, continuing to tell him how good and tight he felt, giving him constant reminders of what she was doing to him. The bed was now actively pummeling the walls, adding more cracks to its smashed surface, the legs lifting under her forceful fucking and displacing itself from its original position; the towels slid around the top of it as well, falling to the floor, cum joining them - with more cum to come! It was an absurd, erotic scene, a small a girl as Melanie dominating her muscular hunk of a boyfriend, the difference between their bodies almost comical. But anyone who saw or knew what Melanie had sticking from her crotch would understand completely.
