He quietly moved naked into the room, before checking the bottle still in his teeth. It was almost empty.
Paul was shocked and confused, not sure when he had drunk all his wife's breast milk from the bottle, but couldn't deny. He felt thirsty.
Knowing he would need to get more, Paul stepped out of the room while unscrewing the cap and drinking the rest of what there was. It was delicious.
Paul was still thirsty, so when he got to the fridge he pulled a bottle out to prepare for Henry, and a second one out for himself. While he was heating up the bottle for the boy, he opened the other one and downed it in seconds. Then swiftly drank the one he'd meant for Henry as well.
He was just about to reach for a third when a devious thought hit him. The relief of swallowing with his dick coupled with the creamy cool breast milk from the fridge. Paul didn't even hesitate, opening another bottle and prying his still stinging urethra open, he brought it up to his tip and poured the contents right down. It took a few moments and a little bit of persuasion to get his cock to drink all of his wife's milk, but eventually he'd drank it all into his balls.
It was blissful.
He could swear he was tasting his wife's cream with his testicles; it was sweet with notes of vanilla, and slightly nutty. So specific, Paul was certain he was not imagining things, as he squeezed his junk, feeling the liquid churning inside his sack, just one nut filled his hand completely being nearly the size of a softball. He gave himself a quick firm squeeze on his surprisingly soft nads. His massage on the outside of his balls felt good. Relieving tension throughout his body, but especially his nuts. It was a different stimulation than he was used to, eliciting tiny bursts of pleasure deep in his dick, like his cock was enjoying hundreds of tiny micro-orgasms with each squeeze
All this milk mixed with the cum left in him from his earlier sex with Henry. Not as much as before, but the sperm was still active, and still changing Paul in ways no one could have predicted. His stomach hardened, his abs gaining more distinction and strength, and his pecs firming beneath his a-cup breasts. The muscles in his legs swelled again slightly, and if his arms were like steel before, now they must be tungsten. His breasts swelled slowly, barely noticeable at all, in order to accommodate the increased number of mammary glands his body had grown, all of which started to begin the process of making milk. His nipples elongated and flattened till they were sticking out over an inch and at least as wide around as a pencil eraser. His areola darkened, preparing themselves for what was to come. All these changes made Paul hard, and with Paul playing with his balls, began edging towards orgasm.
Paul, oblivious to all this, rummaged through his fridge, looking for any more milk he could find. There were only two bottles left, one barely half full. He absentmindedly unscrewed the lid on the full container and polished it off in seconds. His belly now finally feeling full, he moved to the last bottle.
Henry! Paul was making it ready for the boy! How could he forget to feed his wonderful sex god of a son! He had to mix the bottle with some formula, but he couldn't neglect Henry's needs any longer. Any of his needs…
It took the last of their formula, but Paul was ready to take care of the boy, sauntering back into the room with that perfect phallus. Lifting the boy out of his crib, careful not to disturb his sleep too much, Paul fed Henry the bottle while gently stroking his own dick. They sat together in an armchair he had put in the boys room when he was born, Paul cradling Henry in his arms. His dick felt nearly on edge, but didn't want it to stop. Flexing his new abdominal muscles, he forced his bubbling orgasm to subside and moved his now free hand from stroking himself to caressing his boy. He released Henry's penis from it's tight diapered confines as it began to stir from its sheath, but focused his attention to Henry's sleeping face.
Henry was so peaceful, nestled up against Paul's chest. Paul's heart nearly burst with love for him, mind filled with endorphins and surging hormones. Paul was overwhelmed, eyes filling uncontrollably with tears as he held the boy against his naked body. Henry was completely finished with the bottle when his father lost control of his emotions, and the tears fell on his cheeks as the man feeding him tried and failed to fight them back. Henry let go of the bottle, still hungry after everything he'd been through, when he noticed his father's new darker areolas and their swollen nipples, a small bead of white creamy mother's milk forming at the tip. Henry reached out and latched onto his father's breast.
Paul let out an involuntary yelp! His boy was feeding from him! He was sucking on and gently chewing his sensitive nipples! Paul was so close to orgasm, and here his boy was milking his extra sensitive breasts. Henry was gonna make him cum. Paul was gonna cum all over his baby boy's backside, and Henry was the one who would make him do it!
It was too much for Paul!
He quickly scooped up Henry and ran for the hall bathroom. Flipping a light and shutting the door, he knew he was seconds from exploding when he stepped into the tub. Paul's breasts were too new to provide Henry with the meaningful meal he needed, and his one breast was already running dry when they made it to the bath. Desperate for a drink, Henry bit down with his gums and sucked hard on his father's nipple. The pain and pleasure merged again in Paul's mind, setting him over the edge.
Paul fell to his knees as his ejaculation forced itself through his dick, erupting from his tight hole with the force of a shotgun plastering his chest and Henry's backside with modified cum. All the milk he'd drank had revitalized his dick enough for another orgasm, and it was a doozy! Paul was dazed after his release, slumping backwards against the wall, but Henry didn't stop chewing on his nipple. It wracked Paul with pleasure, but was too much for him right now, and he had to push his boy away.
He held Henry between his legs for a moment while he caught his breath, which was just long enough for the boy to see something he liked. Henry saw his father's cock covered in a recent orgasm and assumed it was more milk. So he reached up to the still spasming tip, and did his best to latch on to the leaking dick. Henry liked the taste too! The milk and cum mixture tasted salty and sweet in a way no other milk Henry had enjoyed before did.
Paul meanwhile, was on the verge of blacking out before he felt something massaging his tip. Shooting upright he looked down to see his boy on his cock. He was in heaven, elated to see his son sucking him off, but he couldn't let it continue. It was too soon! He wasn't ready! And his cock was still so sensitive from this past orgasm, that if Henry continued, Paul might have a heart attack right there in the tub with him.
No, instead, Paul figured the boy was still hungry, so lifted him off his dick and offered him his other nipple. Henry was happy to suckle at his dad's breast, and lucky to get a bit of that tasty dickmilk with his breast milk.
Paul was ecstatic. Each time Henry sucked on his nipple, he felt rocked by another micro-orgasm. He needed to return the favor. So, gently massaging his boy's balls, he teased Henry's dick further from its hiding place. Once it was half hard, the two foot cock on full display, Paul lubricated his hand with his own milky jizz and began stroking Henry along his entire length.
He gripped the boy's shaft firmly, careful not to be too hard on him, Paul stroked his mammoth penis. Starting from the tip, Paul slowly slid his hand all the way to the base, then squeezing just a bit tighter, steadily worked his way all the way back up to the top, rolling his wrist to slide his hand around Henry's gargantuan prick as he leisurely progressed upwards.
Down… then back up… then down again.
The entire two foot journey Paul's hand took to pleasure his son lasted mere seconds, but for both parties involved it might as well have taken a lifetime. Henry was getting antsy at the feeling of having his cock tortured by these slow strokes, but Paul just bent his neck to kiss his boy on the forehead, before forcing his baby's mouth back up to his nipple.
By the time Paul had made it to the base of Henry's cock a third time, the shaft had reached its full height and hardness, foreskin peeled all the way back to reveal the angry red head of Henry's godly prick. The masculine spire looked like a baseball bat glued to the crotch of the toddler, it was so out of place. Like sticking a telephone pole on the back of a moped. So fat that Paul couldn't reach his fingers all the way around with one hand and so long a prize stallion would have felt self-conscious, Henry had the perfect cock as far as Paul was concerned. He could hear his son's balls preparing to unleash their load from this superior penis, and Paul was ready to worship this divine instrument.
He picked up the pace with his hand swiftly. He tried desperately to get his mouth all the way around the head as his hand moved with a fury. He jerked the boy off while suckling at his tip. He went as fast as he could, but there was so much cock! He couldn't pump with just on fast enough. Shifting himself as best as he could to keep Henry on his nipple, not knowing he'd already run dry in that breast too, he wrapped both hands around this beast, one above the other and began to jerk him off as quickly as he could.
Slick. Slick. Slick. The sound of Paul masturbating Henry, dick wet with pre and Paul's jizz. They went faster. Hands moving in a blur. Paul needed to make this thing cum. Henry was shifting back and forth. Pumping his hips involuntarily into Paul's hands. Paul pumped his hands with the motion of the boy. Henry wanted him to go faster, but couldn't make him. Paul was strong now, Henry couldn't knock him about like he had before. He was at Paul's mercy. And Paul wanted to help. Afterall, He needed Henry to cum.
Slick. Slick. Slick.
Paul needed that cum. Slurping his mouth over Henry's tip. Tongue darting into his slit. Tasting the pre. Tasting what was leftover. He could smell Henry's masculinity off this godly cock. He could taste some of Steve's asshole on the tip still. He would want some more of that too. But right now he needed Henry to cum for him.
Slick. Slurp. Slick. Slick. Slurp.
Henry was happy to oblige.
Paul felt the orgasm coming early, it had so far to travel to reach his waiting throat. Henry's urethra stretched wide as a thick load moved up towards his father at lightning speed.
In a flash, Paul was blown off Henry's tip by the force of ejaculation. A firm half a cup was shot straight down his throat, and he coughed uncontrollably.
It took him a moment to compose himself, desperate to get ahead of the rest of Henry's precious cum flow. He bent the boy's dick slightly to bathe his chest and crotch in cum while dealing with his coughing fit. Henry was pushed away from his father to the other side of the tub by the sheer force of his own continuous geyser, landing on and closing the plug. He came in a single unending flow of nearly pudding thick, sperm dense jizz, plastering his father from head to toe and creating a puddle at least two inches thick in the bottom of the tub.
Paul composed himself under the spray of Henry's cum. He opened his mouth wide to catch as much super baby cum as he could, all while rubbing the excessive load into himself, scrubbing it into his skin, lathering his hair and scalp with it like it was a shampoo. As Henry's flow slowed down - the remains splurting out in more watery arcs of jizz, more similar to a normal persons cum, if still four or five times the quantity - Paul reached down to scoop the thick puddle of the floor of the tub into cupped hands and drink it down greedily. He even scooped some up, lubing his two forefingers, and jamming them into his cockhole with the force of abandon, before spreading the hole as wide as he could and scooping handful after handful into his burning dickhead. The pain of being stretched was mitigated by the pleasure of swallowing with his cock, and especially by the knowledge that it was Henry's sperm his cock was drinking down. With his cock full and so much left, he tried to drive it all faster than it would dry, scraping up what he could into his hands. With his fingers so thoroughly coated in the stuff, Paul wanted to try something he hadn't tried since highschool. While down on his hands and knees, bubble butt sticking up into the air, he slathered his fingers with as much cum as he could, and positioned them over his anus. Relaxing his sphincter as much as he could, he pressed against his back entrance and forced one finger inside himself. Going much smoother than his first time with his cockhole, he was able to get the other one in and liberally coat himself inside and outside with Henry's semen, before getting his middle and pointer as far in as he could and pressing down forcefully on his prostate. He enjoyed a quick hands free orgasm from his anal stimulation, even if it was a dry orgasm with how spent he was.
Henry could only watch as Paul pleasured himself with his cum. He was dazed. He had never cum that hard, and his body, powerful as it was, was struggling to keep up. This triggered another change in the boy. His hormones went haywire again, as his body fought with a cocktail of super serum and his own natural and unnatural hormones, and the complement of new hormones he'd ingested in his father's mutated milk. His belly got bigger, looking like more healthy baby fat to most, this new size was the result of his prostate and various seminal ducts widened to accommodate more cum. Then, with a strain and a quiet crack, his chest seemed to barrel outwards to accommodate a larger, stronger heart and bigger lungs. His father was so engrossed in his own debauchery that he missed Henry shift his back and stretch his legs till he'd gained at least four more inches of height, as well as similar growth in the length and girth in his dick. The muscle density in his arms, legs, and core also doubled, his body desperate to not be overpowered again.
Paul only became aware of him when he made a whimpering noise, the act of growing so quickly not being without any pain. Paul was so lost in his own hedonism that he couldn't even recognize the changes in his son, and thought maybe Henry wanted to share in drinking this wonderful super semen that Paul was enjoying so much. Running his finger along the tub, Paul scooped some up, and placed it in Henry's mouth. The baby did not care for the taste of his own cum! It was far too bitter, and nothing at all like his dad's sweet dickmilk that had tasted of melted ice cream, or his breast milk that was even richer than his mother's.
He forced his father's finger from his mouth and shook his head violently. Paul couldn't help but laugh at the boy. He picked him up under his arms and stood up with him, holding him aloft. "Thank you, Henry. We're gonna be doing that again, a lot more from now on!"
Henry responded to his father's declaration by pointing his softening penis at him, and letting out a solid stream of piss. Paul frowned at the boy as Henry let out a playful giggle. Despite everything that's happened to him, he was not yet ready for pissplay, nor did he ever want to get into it.
Figuring the best thing to do at this point was to clean off, Paul pulled the plug and started the shower, cleaning himself and Henry from their now dried jizz and golden shower. As he washed the boy, careful to clean under his foreskin, he noticed some coarse peach fuzz near the base of his dick and on his back near the top of his ass crack. Henry was beginning to grow pubic hairs already!
Paul was so engrossed in this discovery he almost didn't notice his own body changing. At first, it went unnoticed by him; His lips became more full and red. The remaining hair on his arms and legs falling out, his own pubic hair falling out in clumps under the shower head, and his chest and belly becoming bare. The hair on his head grew longer, with the new hair coming in looking golden blonde instead of his existing brown.
Then came the changes he could feel. The bones in his arms and legs lengthened with a creaking and a snap. His spine stretched as he flexed his back muscles, sore for no reason he'd thought, not knowing that those muscles were growing larger and stronger. His biceps and triceps swelled out, giving him almost cartoonish 16 inch arms, and his deltoids could similarly bulk any time he flexed his fingers. His thighs, already muscular and toned, looked herculean as the changes continued to strengthen him. His washboard abs glistened in the water of the shower: Paul had never had a 12 pack before, much less on you could all but grate cheese on. His ass maintained a healthy bit of fat, bubbling out and jiggling a bit if he smacked it: it would probably bounce when he jumped and sway when he walked. But the muscles underneath were not weak at all. His glutes could probably crack a walnut if he flexed them just right.
His breasts swelled again, tips now near constantly leaking milk slowly, Paul felt confident in calling these his boobs. They were large for b-cups, but the nipples stuck out nearly two inches now, and were as fat as one of his fingers. He even worried if Henry could still nurse from him or not.
He felt his jaw crack, his mouth now opening wider, his lips feeling more sensitive to the touch, and his tongue became longer. His cheeks felt puffy.
Paul quickly finished washing himself so he could look at these changes in the mirror.
He stepped out, and still dripping wet, posed while holding Henry. He looked like he could be some sort of Adonis with these immense muscles. His face was pretty more than handsome however, and with his long hair and swollen ass, even Paul might mistake the image he saw in the mirror for a particularly tall, muscular, teenage girl, especially from behind. A sentiment that was more true than he knew, as in every way but mental, Paul was now 16. Right down to his DNA that had been modified by bathing himself inside and out in Henry's super baby cum. He was taller and more muscular than he had been in his youth, but Paul was a teenager again thanks to his baby's superjizz.
His face still deflected most thoughts of femininity from the equation. But still, it made Paul wonder. Is he still Henry's "father", now especially with the lactating breasts? Is "he" even "him" anymore? Paul considered it, but ultimately wasn't prepared to take on a female role in his life. He would take some more time to consider how he should be addressed now that he's changed so much, but honestly hoped he and his sons might even be able to move away from ideas of masculinity and femininity, becoming a new type of humanity altogether. That thought was somewhat alluring.
He could not deny, he was a bit scared of what was happening to him and his boys, and he didn't know where it was going. He didn't know how he was going to explain his new form to his wife; he looked so different she would more quickly mistake him for a stranger than her husband. But he didn't want it to stop. And as he dried himself off, and looked down at the sleeping Henry in his arms, he felt confident he would continue these changes still.
Heading to Henry's room, Paul locked the door behind himself and laid down on the floor with Henry in his arms, covering themselves with a blanket, and drifting off to sleep.
