Pholus looked down when he awoke, seeing a very familiar sight. A pillar bigger than anyone could take, with a pair of balls that could impregnate a Japanese city in a day. That particular measurement had been pretty funny at the time. Knowing that he produced up to 20 liters of cum with optimal nutrition was a bit less so. Especially given that it meant a cock hole he could stick his thumb down.
He'd done the math one time. He came over 11 meters (35 feet) a day. 11 meters of hypervirile hormone filled, supernaturally charged jizz, capable of either making him the most prolific father in history, or giving elderly men and women a good night out. He groaned, his hips popping as he shifted his weight, his balls large enough to force them apart at night. It hadn't been as much an issue when he'd fallen asleep against Bill's perfect ass, though the rug burn was a bit annoying, but waking up alone because all of them had been totally drained was... almost demoralizing. Their bodies couldn't handle being together, at least not without a couple IV tubes to prevent them from totally dehydrating as their dreams became increasingly focused on bodies bathing in their cum and pregnant bellies... He groaned in frustration as that mere thought was enough to soak the bedspread, his body eager for another day of release.
He rolled out of bed, muscles tensing to hold up his swaying sack, as he forced it behind his legs. He remembered when a jockstrap could contain his body. Not anymore, as his dick and balls rested comfortably against his knees, constantly dripping a stream of cloudy pre. They'd given up on living at home. It was just... too much. Their parents and siblings affected by the cloud of musk that constantly followed them, the therapy sessions for dealing with inadequacy. Bill had even gotten a paternity test, his dad unable to quite believe that his son was...
As usual Pholus's breath was taken away when he saw best friends. They radiated an aura of... he couldn't describe it as anything other than attraction, even when they were matted, smelly, and drinking their first chemically balanced shake of the morning. He grabbed his, and joined them, settling into his usual spot, pelvis thanking him for giving his balls some support against a molded padded surface.
"So... what's left?" He asked, sipping.
"Same as usual. A day of fun fucking some tubes and then a night of fun fucking some tunnels." Bill said, as Beth blushed, her nipples tenting already.
"And what about Persephone?" Beth asked, unable to resist pressing her shoulders back, her nipples leaking against the fabric.
Bill made a face. "Cerberus, Cattle, and Hind." He confirmed. "I have no idea what the Hind would be. Cerberus could be three puppies if we wanted to get it over with... Cattle, ugh, I don't even what to think about it."
Beth made a face. "Look, you two are amazing as partners, and my sex life has never been better in any of my memories, but... fuck, Pholus can barely walk. I don't want to give her ideas. I'm not even sure what three puppies would encourage her to do."
"What is a hind anyway?" Pholus asked. "I know it has to do with the Argonauts, but I don't remember much about it."
"I think it's a legendary leather bit of fabric. They killed a something and skinned it, before the Ship of Theseus lost the entire crew in tragic Greek hubris." Bill said.
Beth groaned. "No, that's the Golden Fleece. The Hind was a deer." She said. Sometimes the boy's habit of sneaking off in the middle of class and flooding the third floor bathroom meant that they lacked a certain experience with the classics. Of course, she joined them extremely frequently, but she at least would look stuff up.
The other two looked surprised. "I thought that was a good flow. The Argonauts was a cool story." Bill said. "So many possibilities to break it."
"So... what? You thought we needed to look for a golden piece of vellum and... we'll, what? Grow to the size of boats?" Beth joked.
Bill's face went white, as he stared at the TV. Normally, it was running porn, to help them get in the mood and raise the baseline level of horny. This time... there was a line of the interchangeable doctors the three of them vaguely remembered hanging around. Pholus remembered his paper that had changed their lives, that had been years ago. Since then, they'd been reacting to each other, becoming larger and larger, producing more and more, tests to increase their output being trialed and run, always accepted when they were horny enough, as in any time between when they'd doused the bedroom with their morning wood and when they got to breakfast.
There was a person on screen. Talking about the Nobel Prize in Medicine. Apparently ratcheting up Humanity's horniness and average dick/bust size had had some... effects. It wasn't exactly the fix to everything, but, it was undeniable that violent crime rates had fallen, and the endemic declining population had been halted. Thanks to them.
And, with the gold medal, came a vellum certificate. "Fuck you Persephone." Bill groaned.
The world shifted, Persephone laughing at taking their exact words. Wasn't like there was a such thing as a definitive myth anyway, just what people remembered.
***
Bill, Beth, and Pholus couldn't remember the last time they'd walked. They were too heavy, their bodies too needy. Most of the day was passed in a haze of jizz, milk, and injections. So many IVs to keep them hydrated and producing at maximum rates.
It had been... sort of an ego thing at first. Bill and Pholus, showing off to each other. Pholus had been the one to respond most favorably. Bill regretted the day he'd grown longer than his torso, his chest pressing against his massive shaft when he was standing. The moment he'd finally been larger than his best friend. That's when Pholus had asked for a few more of the experimental treatments. Beth had followed suit. She used to be able to reach the ground with her front legs. Then had come the harness, since there was too much pressure. Her growing breasts had fixed that soon enough. The surgeries to deal with her legs being spread too wide weren't... a good memory.
Still, they'd encountered the same. Growing well beyond anything reasonable. Nothing that could possibly fit in... to be honest anything.
Occasionally they all emerged from their libido induced haze at once. And managed to catch a game of Smash. To chat. To enjoy a good meal together, rather than just the IVs.
Occasionally, it felt like Persephone won. They were trapped in their bodies, a slave to their lusts, exactly where she wanted.
"Bill?" Pholus asked, voice a bit rusty from not speaking except to moan, or scream.
"I'm here." Bill replied. It'd taken a couple trucks, but they'd managed to arrange themselves so that they could hold hands. It... helped. It really helped, even when they couldn't consciously squeeze back. All three of them together.
"You two up?" Beth asked, squeezing Bill's other hand.
"Yep" "Yeah." Bill and Pholus said.
"Two more to go. Cerberus and the Cattle." Bill said after a few seconds of silence.
"You really want to tempt her?" Pholus asked, looking in front of him, his cock most of the length of the warehouse, his balls larger than the average suburban pool.
Beth laughed, exhausted already. "Fuck it. We've been through this shit together."
The three sat there in silence for a minute, desperately holding onto each other. "Thank you. For being here. Helping me stay sane." Bill said.
