THIS IS A LOT MORE LIKE A RECAP OF A FIC THAN A FIC ITSELF; ASSUME EVERY EVENT MENTIONED HERE WILL BE EXPANDED AND TOLD WITH CONVENTIONAL NARRATION. It was less a problem back before the world changed, when Gau was an enthusiastic, energetic, eager little kid. Things got a little awkward after the end of the world when they met him again and everyone got to learn how loudly he jerked off, which. Which, well, there were certain things that Sabin did during the three years of his life that everyone else called the End of the World that he did less because he wanted to do them and more because someone needed to and he had to be that person, and somewhere around the middle of that list is "talking to Gau about how to jerk off quietly." Things got more awkward— more awkward for him, not for Gau, because Gau never had any shame whatsoever, as again everyone found out in the summer when they found him out in the Veldt running around completely naked. But things got specifically very awkward for him near the end of their big adventure to save the world when he realized that out of everyone Gau had gotten a huge, mind-consuming crush on him. And since despite their best efforts Gau's social abilities could be best described as "terrible", that meant he had to put up with varying types of attempted seduction, ranging from Gau sprawling out naked in his tent at night to one time that he has seriously managed to wipe all memory of from his brain, when Gau actually pinned him down and rubbed against him, naked and hard. The worst part is that Gau is growing up hot; lithe and muscular, tanned all over. If he was a few years old— and he hadn't known him since he was 13— he might actually consider it. But he wasn't, and he had, and plus he was one of the kid's (many) father figures. He was the one to teach him to /shave/, even. Which, of course, he didn't take to at all, and sadly the short beard and streaming hair made him look like he was maybe in his mid twenties and not, oh, still seventeen. [...] [ and then sabin sees gau getting fucked by a behemoth or smt ] More shocking than seeing a behemoth passive like that was what Gau was doing with it. Him. The behemoth's hind legs were spread and Sabin had an all-too-clear view of its cock, the kind of thing he'd expect to see in nightmares. It was a pulsating red-purple, covered in thick ridges and spikes, like some kind of torture device. As Gau growled and gobbled against the Behemoth's neck — not even an inch away from its huge fangs; every time the Behemoth growled back its lips turned up, showing off teeth a handspan long, yellow-red; all it would take is a tiny sideways motion and the fangs would be straight through Gau's neck — the Behemoth's erection kicked and pulsed, getting even bigger, knobs and bulges flaring out along the shaft, the bloated head fattening, another row of spikes slowly unfolding along the shaft. It twitched, a shimmering line of fluid spurting out with enough force to hit Gau's legs; Gau grunted and leaned more heavily against the Behemoth, his profile almost vanishing in the Behemoth's shaggy fur. The Behemoth let out a particularly deep, lingering growl, the kind that made Sabin's skin break out in goosebumps. Gau laughed, the sound bizarrely human after nothing but growls and snaps, and he pulled back far enough to bump his nose against the Behemoth's. The Behemoth opened its mouth and its tongue lolled out, thin drool dripping down its length, all across Gau's chest, and then Gau leaned forward and pushed his open mouth against the Behemoth's huge fangs, kissing. The Behemoth practically shoved its tongue into his mouth, drool shining across Gau's face, smearing over his skin as they kept pressing against each other, Gau swallowing over and over, drinking its drool down. His hands clenched tight around the Behemoth's shoulders, working back and forth under the fur, and for the first time Sabin noticed Gau's cock, jutting out the side of his skewed loincloth. Gau rutted against the Behemoth's foreleg, smooth shaft grinding back and forth against him, his entire body arching up into their kiss. Gau pulled back, his face shiny with drool. He growled shortly at the Behemoth, and the Behemoth rolled onto its side with a thud Sabin could feel even at this distance. Its cock was erect, enormous, spanning up along its underbelly. Gau knelt down, sliding his fingers through the Behemoth's thick fur, matted and dark with precome. Sabin swallowed thickly, even more sure he shouldn't be watching this, but he couldn't bring himself to look away. Gau settled himself against the Behemoth's cock, the thing almost as big as his entire body. The casualness with which Gau straddled it made a strange twisting rise in his stomach. His legs wrapped around its base, chest pressed tight against it. The cock shuddered, bucking like it was a wild chocobo, and the massive muscle was strong enough to lift Gau up for a brief moment before it came slapping down against the Behemoth's stomach. There was an explosion of come as it pressed tight against its stomach, huge ropes of come spraying in a thin, wet mess all across the Behemoth's underside. Gau leaned forward, mouth open wide, come spraying across his face and dripping down his shoulders as the Behemoth convulsed, rocking his cock against Gau's body. Sabin thought that might be it; that they were done, but neither of them even slowed down. The Behemoth's tail lashed back and forth wildly, flattening the grass around them. Gau pushed his face right up against its bizarre, animalistic cockhead, pointed like a spear-tip, and laved his tongue across the sloppy flesh, his hands tugging and twisting at the huge backwards-curving spikes jutting from the crest. The Behemoth growled and hissed, another huge volley of come launching from his cock and wrapping around Gau's head in fat, flabby strands. Its come — precome, who knew — was thick and heavy, but there was just so much of it that it poured in globby sheets down his face and jaw, drippy strings hanging from his narrow chin. Gau kissed, open-mouthed, the huge opening of its cockslit, and Sabin gaped as he slowly worked his face inside, nose dimpling into the wide hole, chin rubbing up and down over the slit — and fuck, Sabin felt a sick lurch in his stomach when he thought of Gau touching his stubble, frowning at the rough edges, saying it was too prickly — until with a wet swell of fluid his jaw sunk inside the Behemoth's cock. Gau's Adam's apple bobbed again and again as he worked deeper, thick fluid still spilling out over his cheeks as he drank down its precome swallow after swallow. Gau kept pressing further, head slowly sinking inside the Behemoth's cockhead, the huge flesh distending as Gau pushed deeper. Gau seemed to reach a limit, the cock not quite elastic enough to fit his entire head. He pushed harder, fingers gripping the huge fat lips of the Behemoth's cockslit and pulling it wider, but he still couldn't fit any deeper. He struggled harder, until the Behemoth growled, definitely annoyed. Gau pulled out with a lewd slurp that sounded clear all the way to Sabin's vantage point. Precome poured out from the Behemoth's unblocked cock, its cockslit gaping wide open, revealing nothing but a constant upwelling of thick, translucent come, pouring in chunky threads over Gau's body. The Behemoth's fur was matted with it, the heavy, shaggy fur on its underbelly plastered flat to its skin. Gau licked around the distended ring of its slit in apology. Come poured out in a constant stream, more viscous now, huge orbs of fluid dripping down and exploding like bombs when they hit the ground, spraying fluid everywhere. Gau had one hand braced around the massive swell of the Behemoth's cockhead, rubbing and stroking along the crested spikes all the way up to the spearpoint tip, his other hand tugging and rubbing at his own cock, sharply erect and standing straight up his stomach. He jerked off his loincloth with a snap, tossing the shred of leather aside as he bodily rutted against the Behemoth's cock, face buried against its cockhead, his feet wrapped around its base, just above its sheath and bloated balls. The Behemoth made a strange sound, growling and yipping, and Gau pulled back, a solid sheet of come webbing between his face and its cockhead, his features completely obscured by the mess of fluids dripping down his face. He shimmied up the length of its cock until his legs were spread around its cockhead, ankles locked around each other against the tube of its urethra, a thick flange along the underside of its cock. Sabin's breath caught in his chest, thinking Gau would thrust his cock inside the Behemoth's cockhead, but the reality was so much worse. Gau shifted somehow, straining atop the Behemoth's cock, and it took Sabin a long moment to realize he was trying to fit it inside him, in his ass. The thing was the size of his entire body and he was trying to put it in him. There was absolutely no way — it would kill him. But Gau hadn't seemed to notice the utter impossibility of what he was trying to do, and so he rocked himself back and forth atop the Behemoth's cock, his ass rapidly becoming coated in a thick, dripping layer of come, a practical river of it drooling between his ass cheeks and slopping down between his legs in a messy stream. He pushed himself harder against the tip, the muscles of his ass visibly clenching and relaxing, opening up, but even the pointed tip was big enough to fit his face, and the fat rim of its cockhead was almost as wide as his hips; there was just no way — Sabin's eyes bulged as Gau's asshole caught against the tip of the cock, his entire body suddenly tense and straining. He stayed taut there for a long moment, long enough for the slime of precome to sluice down his skin, revealing the very tip digging against his asshole, Gau's entire trembling body astride the tip as he tried to take it inside him, his anal ring already spread terrifyingly wide. Gau screamed, and Sabin lurched forward, almost toppling off his vantage point, before he saw that Gau was coming, come shooting in lances across the Behemoth's matted fur as the head ever-so-slowly sunk inside Gau's ass. His ring looked swollen and red, broken open, but as he stared he saw it clench and then open further, practically unfurling around the Behemoth's cockhead. Gau sunk down onto the inhuman cock in uneven lurches, the head spreading him wider and wider as Gau hissed and moaned. Gau went limp, body flexing and clenching against the Behemoth's cock, pathetically small compared to the huge animal. Gau's ass clamped down, pinning the fat spikes on the Behemoth's cockhead tight against its shaft, as even more somehow worked inside him. Even flush against the shaft the spikes were huge; lewd slopping noises sounded as they broke the seal around Gau's ass, precome pouring from him along the indents between the spikes. His ass looked... like meat, like nothing that should be attached to a human, his skin hot red and glossy, shining with thick liquid, his anal ring swollen and distended into puffy, soft-looking slabs, bulging out around the spire of the Behemoth's cock. Slowly Gau sunk deeper, and even the fat spikes somehow fit inside him. The spikes spread against Gau's soft guts, bulged outward, straining harder and harder against his ruined asshole. The moment they vanished inside him the Behemoth flexed its cock, the entire length bulging outward, and Gau's stomach inflated, an uneven lump flaring out across his lean stomach before subsiding, the heavy barbs locking them absolutely together. Gau lurched, his entire body trembling, and he let out a ragged, hoarse scream, enough to set Sabin's teeth on edge. He came again, cock erupting again all over his chest, and he weakly reached up, smearing his load across the bulge of his stomach, grasping at the Behemoth's cock through his strained skin. The Behemoth growled and got to its feet, Gau bobbing at the end of its cock, arms and legs dangling down into the trampled grass. The Behemoth took a lurching step forward, and for a moment Sabin lost track of where Gau was, the moving legs and shaggy fur obscuring his vision — he thought the monster had knocked Gau forward, dragging him forward across the ground, except then he realized Gau had taken it; his arms and legs digging into the ground, tense and ready, an absolutely terrifying amount of cock distending his stomach, bulging it out past his ribs. His mouth was hanging open, his chest heaving as he gasped, throat working without any sound coming out. But then he finally moved, screamed, an inhuman yowl, and in response the Behemoth shoved forward again, burying almost a third of its gargantuan cock in his skinny frame with a meaty, awful thwack. Gau let out a shaky choked noise, rutting his broken-wide ass against the Behemoth's cock, like it was somehow possible for him to fit more, with his stomach bloated out like he was speared through. Even with that impossible length inside him, the Behemoth's cock still stretched out, little more than the tip inside him. It visibly pulsed, throbbing with an uneven rhythm, the raw purple-red skin of it rippling and shifting, thick veins bulging to the surface with each of the Behemoth's heartbeats. It thickened down the length of it, and the knobbly lumps and ridges got bigger and bigger, like fat pearls under its skin, running in zig-zagging lines down its shaft. It flared out into fat ridges at uneven intervals, even the smallest wider around than Gau's waist, and more sets of fleshy barbs stretched out from the ridges, flaring and contracting as the Behemoth flexed its cock, the length twitching up with enough force to slam Gau's back against it's filthy underbelly. Sabin couldn't understand how Gau could take it, not just not get ripped apart but by all signs enjoy it. The Behemoth drew back until its spikes bulged out the flesh around Gau's asshole, the shaft emerging coated in thick yellowish precome. It plowed back into him with no warning, what had to be feets worth of cock plunged into him, his stomach bloating out again, like that was possible, like his tiny teenaged frame could possibly fit that without exploding into a heap of gore. Gau pushed back, fucking his ravaged body back against the colossal cock as the Behemoth pounded him. It withdrew with a ragged lurch that deflated Gau's body only to slam forward again, again and again, both of them rutting like wild animals. Yellowish precome streamed down the Behemoth's cock, pouring out from Gau's fucked-open hole, heavy sheets of ooze erupting from Gau's overfilled ass with each inward thrust. They began to get into the motion, Gau shoving his body back and forth, the Behemoth thrusting in awkward, short movements, its huge claws tearing up the grass at its feet. Sabin couldn't believe he was still watching. He could hear their noises; low growls and harsh cries that he honestly couldn't tell who was making them, Gau or the Behemoth. Even the wet squelch of their fucking, precome lubing Gau up, overflowing from his broken-wide ass, it carried in the still air, wet, heavy noises, like — like nothing he'd ever heard before. Gau braced himself against the ground, fingers and toes splayed wide, digging into the dirt, and the Behemoth slammed into him, like it was fucking something that could take it, cock pistoning back and forth in sharp, rapid motions, jerking Gau's body back and forth, the inward thrusts sending his entire body jerking up into the air, thin arms braced and trembling from the strain. He collapsed back to the ground with each outward thrust, his stomach deflating, his body going limp, and there was a fraction of a second where he just lay there, legs twitching, arms quaking, before the Behemoth drove into him again, sending him lurching forward. And the Behemoth's cock wasn't smooth, wasn't something that slid in effortlessly; the surface of the shaft was a mess of thick ridges and bulging knobs, spiraling across the surface; he could see Gau's broken asshole still catching against the fist-sized obstructions, the heavy ridges catching across his cheeks in an uneven, stuttering rhythm before the force of the thrusts drove them inside. His entire ass bulged outwards for a brief moment on the withdrawal before each ring burst free. Sabin would think he was dead if he wasn't so vocal about it; he was yelling and squealing with each thrust, his cock disturbingly hard throughout it all, even with his body looking like it would burst apart around the cock inside him. Its massive, pendulous balls rolled and twitched in their furry sack, loose enough that they draped back across the ground with each withdrawal and slammed into Gau's body with each thrust, each one alone as big as his thin torso, the sack itself big enough to entirely bury him under it. It swung forward like a massive weight and smacked against Gau's ass, a spray of precome exploding in all directions with each hit, the Behemoth snarling with each brutal thrust. Precome was pouring out of Gau's ravaged ass, slopping in waves down his thighs and splattering against the impossible length of the Behemoth's cock, all its spikes and knobs and ridges greased and shiny with it. The Behemoth's fur had gone from wet and matted to soaking, wet hanks dripping precome in slashing lines with every movement, a thick dense lather forming on the Behemoth's underbelly, splashing in thick dollops against Gau's shoulders. Finally the Behemoth roared, a cry that echoed for what seemed like miles, and slammed into Gau's distended body as deep as possible, the massive shaft stiffening and bulging even further. Its spikes flared wide, the ridges swelling thicker, and at the very base, thankfully too far down for even Gau to fit it inside, a huge swell of muscle bulged outward, thicker than Gau's entire body. Gau went tense, his mouth open in a silent scream, drool — or more precome; he was absolutely slathered in it — dripping from his wide mouth. His stomach rippled again, muscles stretching and fighting against the Behemoth's cock as it bore inside him, its come pouring inside. Sabin could see his stomach fill up, his aching, stretched muscles going slack, his stomach swelling until he looked starvation-full, body strangely thin around the smooth, spherical bulge of his stomach. The Behemoth was nowhere near finished; it kept fucking Gau, cock sliding slowly forward and back as it bred him like a wild animal, its heavy come overflowing and spilling out along the Behemoth's cock. It was thick — incredibly thick — and tinged yellow, pouring across their bodies in slow-moving trails, welling up from Gau's broken ass, slopping to the trampled grass below them. It just kept coming, overflowing Gau and then some, heavy cracking, slopping noises sounding faintly as the Behemoth kept moving, churning up Gau's guts with its cock. Sabin couldn't bring himself to look away, eyes caught on the shiny gleam of the Behemoth's cock as it ravaged Gau's hole, crusted so thickly with come that he could only see the ravaged red flesh of his ass after each withdrawal. His entire body was practically buried in the monster's come, the molasses-thick come rolling across his back and clinging to his stomach as the Behemoth spent itself inside Gau's body. It was minutes later when the Behemoth finally finished, its slow thrusts becoming even slower until it finally thrust in and held it, stepping away from the trampled, ruined grass with an easy gait, jerking Gau bodily along with it, his hands and feet emerging from the mire of churned up dirt and come underneath them. The Behemoth took a few slow steps away and flopped over on its side, chest heaving slowly. Sabin waited for Gau to pull off, worry blooming in his head and Gau lay there unmoving, sprawled across the Behemoth's underbelly, his body lurching and shifting with each slow twitch of the Behemoth's cock. Gau finally moved, stretching his limbs like a cat, wrapping his grubby feet around the massive shaft, reaching down with one hand to feel at the swell of his stomach, then moving lower to his ass, leaving a smeared trail of dirt. His asshole was puffy and swollen around the Behemoth's cock, thick come oozing out around it, and Gau lolled back, eyes closed, sliding his fingers through the mess coating his ass. He slowly tugged on his cock with his other hand, come dripping steadily from the tip as he stroked himself, not trying to bring himself off, just luxuriating in the sensation. His stomach and thighs were soon smeared with dirt on top of being coated in the Behemoth's fluids, and Gau just lay there with his eyes shut, making soft, easy whimpers. Sabin felt an awful churning in his stomach, finally able to tear his gaze away. Gau lying there, lying with animals... he couldn't think about it; his brain refused. [...] When he saw Gau again he almost started. After seeing... after that, it was hard to even look at him. It wasn't unusual for Gau for vanish for long hours or even days as they trekked across the Veldt, and when they saw him again... he usually came by at dusk, tired and smelling of the wilds, and it was easy to get him to curl up in someone's tent and fall asleep in minutes. With a sick roil in his stomach, Sabin wondered if that strange spicy smell that lingered around Gau was Behemoth come. His stomach wasn't that swollen, grotesque orb he'd last seen, he wasn't even limping; it was enough to make Sabin want to dismiss it all as if it was some awful nightmare. But maybe there was the slightest hitch in his hips as he loped back into camp, and maybe he could see ragged red seams across the dark skin of his stomach, stretch marks already fading. Gau caught him staring and grinned, that same innocent child's grin he'd always had, but after seeing him suck down a Behemoth's tongue, seeing him work his head half-inside its cock, it just seemed wrong to act... he wasn't even sure what would be right, or how to treat the situation at all. He wished this was just as simple as telling Gau that humans didn't jerk off in front of each other; that at least was comprehensible. [ ... and then gau hits on him again ... ] Sabin couldn't really help it; it was more-or-less his body's completely involuntary reaction to having a really quite attractive guy ('kid', he reminded himself, 'he's sixteen') rub up against him, all bare skin and lithe muscle, and oh Sabin wouldn't even mind it if Gau was just a few years older. Gau moaned as he ground against Sabin, their cocks rubbing against each other, their clothes the most flimsy barrier. Sabin struggled against Gau, actually pushing this time, and flung the boy bodily off him. Gau moved faster than he could see; the instant he realized the throw was unavoidable he moved with it, kicking off against Sabin's chest in a blow that drove the air from his lungs and arcing up in a sharp flip, landing on all fours with teeth bared, growling like a wild animal. "Gau!" Sabin shouted, like he was yelling at a misbehaving pet. [ sabin yells about consent i guess and no-means-no (which gau gets he's just used to a little more violence in the 'no' process) and age of consent (which gau does /not/ get) ] Gau snarled. "In two years Gau will still want this and it will have been two years without any fucking."
