Tommy shuffled into the bedroom as you reamed his bovine big sister, rubbing his eyes and wondering what all the racket was. In your sex-filled stupor, you immediately morphed him upon seeing him standing there.
In a flash, black-and-white floppy cow ears expanded out from the sides of his head, replacing his former ears, along with a nubby pair of female cow horns.
Your little brother lost his clothes as his lower body changed to become similar to Jessica's. After a moment, you were able to take in Tommy's new form.
His smooth hairless chest remained the same, slim and boyish, with cute nipples. As your eyes drifted downward to his waist, the pale skin transitioned to white fur with black blotches, matching your sister's Holstein coat.
His new bovine hips expanded out widely, now at the top of thickly muscled cow legs that ended in big shiny hooves. A cute fuzzy tail swished from above Tommy's new huge jiggly feminine ass.
Between his legs, however, he differed greatly from Jessica.
Swinging in front of him with semi-rigidity was an absolutely enormous pair of humanoid male genitals. His dick was the thickness of a soda can and stretched out two feet in front of him, its fat spongy head the size of a tennis ball.
Beneath that was a massive sack of volleyball-sized nuts that hung down to just past his knees. The pendulous orbs stretched their hairless smooth sack tight with virility.
Upon completion, you admired your little brother's improved form as you began to reach your breaking point plowing your sister's cow pussy. Tommy was now essentially a super-well-hung cow femboy. Finishing rubbing the sleep from his eyes, he smiled sweetly at the sight of his sister getting milked by his mom and brother.
"Hey, why didn't anyone wake me?" he asked, feigning irritation. "I need to be milked just as much as Jessica!" With that he reached down and lifted one of his huge nads, its sheer weight actually requiring a substantial amount of effort from the cowboy.
"I was letting you sleep in, sweetie," your mom replied, changing out a full bucket of Jessica's milk for a new one. "We don't have to milk both of you at once. You know I wouldn't let you go a morning without emptying your balls, honey."
Tommy grabbed his fat meatstick and swung it around idly.
"This wouldn't be an issue if I could just empty them whenever I wanted!" Tommy replied, this time with growing genuine irritation.
Your mom released one of Jessica's fat teats with a sigh.
"You know we shouldn't do that, dear. We make a lot of money from selling the fruits of yours and Jessica's 'labor'," she responded patiently. "I know it's difficult, sweetheart. But the whole family benefits from it."
"Okayyyyyyy," Tommy acquiesced.
This exchange nearly distracted you from the fact that you were on the verge of unloading in your sister's snatch. You groaned out as your balls tightened up and you came into Jessica's cow pussy. The sensation made your sister cry out as she had another milk-gasm, squirting what would be the last of her copious quantities of milk into the final bucket beneath her.
"There you go, honey!" your mom announced happily. She reached a hand up and stroked your sister's huge bulging udder before giving it a kiss. "That might be a new record for us."
You pulled your softening member out of your sister with a pop!, noticing how drenched it was in your sister's feminine cow juice. Looking at the carpet of her room, you noticed EIGHT full buckets of milk, making your eyes widen. You were pretty sure that was way more than what an actual cow could produce in one sitting. No wonder your family profited from it.
Aside from that, your sister's wall was covered in ropes of milk from her enhanced tits, the streams of fluid oozing down the wall until it seeped into the carpet.
Jessica turned and smiled at you.
"Thanks, Ben that was great!" she said cheerfully before pulling you into a tight hug, smearing your body with her excess milk.
"Uhh, don't mention it, Jess," you replied, surprised at the strength of your sister's embrace.
Your mom moved the last milk bucket over with the others at the side of the room, let out a sigh and stood up.
"What about me?" Tommy asked, now slowly stroking his thick beef.
"Now now, baby, you know I saved a bucket just for you," your mom answered, grabbing one empty bucket she had left off to the side. "It's a good thing I brought an extra, I just had a feeling your sister was gonna be extra productive this morning!"
She brought the bucket over to Tommy and set it down on the floor in front of his turgid two-foot member.
"I want Ben to do it," Tommy told your mom.
"Sure, honey," your mom replied, looking over to you and beckoning you over.
You happily agreed and crossed the room to Tommy. Jessica just sat on her bed, resting from the unnatural amount of work she just endured.
Walking up to Tommy, you kneeled to his right side, hip-to-hip, and wrapped your left arm around his back. With your right hand, you reached over and gripped his megameat, sliding your hand up and down sensually.
Tommy sighed at his big brother's ministrations.
Your mom then did something you did not expect. She got up to the other side of Tommy and reached her left hand around his front and began squeezing and caressing his giant nuts, attempting to coax out as much of his bounty as possible. But with her right hand, she brought it up over to behind his thick meaty ass and closed it into a fist in front of his big fat donut asshole.
Tommy gasped and you felt his cock throb forcefully as your mom slid her fist into his enhanced sphincter, nearly effortlessly sliding her whole arm into him up to the elbow. You had no idea how your kid brother was able to endure having his cock stroked, balls massaged, and asshole fisted all at once.
"There," your mom said, "I know how my baby boy likes it."
"T-thanks, mommy," the feminine cow-boy replied, groaning as you worked his huge penis.
Tommy was soon grunting with each thrust of your mom's arm into his ass, and she was soon pumping it in and out quickly with constant schlorp schlorp schlorp sounds. A constant stream of pre oozed from your brothers inch-long piss slit, dribbling down into the bucket beneath him.
"Come on Tommy," you encouraged him. "Let it all out."
"Oh Ben!" he gasped, he gently tugged at your side with one of his arms, silently requesting you to raise yourself up some. You smiled and did just that as the two of you locked lips and started making out, still with you attempting to milk his cock for all its worth. Tommy moaned into your mouth as you wrestled his young tongue.
Tommy's grunts soon were increasing in pitch and frequency as he was approaching a monumental orgasm. He broke off from his kiss with you so he could pant loudly, his prostate being literally punched by your mom, elbow-deep in his guts.
"Oh Ben!" he yelled again. "I'm! I'm gonna!"
"Yeah?" you replied with a teasing grin. "Whatcha gonna do?"
He groaned the loudest he had up to that point as his massive nuts lifted themselves up to his body. Inconceivable quantities of thick cow cum worked their way up to the base of Tommy's dick.
Your handjob and your mom's pounding of his bovine bussy finally overwhelmed him and he fired a solid half-gallon of spooge at the bucket. You weren't exactly aiming it at that moment so only half went into the bucket, the rest firing across the carpet.
Quickly rectifying this, you pointed his huge meat downward so the rest would shoot straight into the bucket.
Tommy just stared at you with loving lust-filled eyes as his balls unloaded below him. Rope after rope of yellowish cream splashed into the quickly-filling vessel. You watched in awe as his cum was soon approaching the rim. You were worried it would start overflowing, but Tommy's orgasm began to slow just in time.
A few final spurts of semen exited his purple pisshole before your pre-pubescent brother let out a big sigh, signaling the end of his climax.
The bucket was filled to the absolute brim with thick viscous fluid, slowly shifting in its vessel as it settled.
Your mom slid her arm out of Tommy's rectum with one last SCHLOOORP! before wiping her assjuice-covered arm on his furry hindquarters.
"That was wonderful, honey!" she said gleefully. "A full bucket! Your brother must have really been doing a good job!"
"Y-yeah," Tommy replied, appearing exhausted.
"We'll just have to be careful and make sure we keep this bucket separate from your sister's," your mom continued. "Wouldn't want to have another instance of poor Ben here getting himself some cereal and accidentally using your cum instead of Jess's milk, haha!"
She lifted the heavy bucket by its handle, careful not to spill any spooge, and brought it over to the other buckets.
She turned back to the two of you and added, "Unless, of course, it wasn't an accident." She winked at you. "Alright, I'll go get your father, and we'll bring these all downstairs to be placed in the fridge."
You assumed she meant you had one of those industrial-sized fridges, cuz the one in the kitchen was nowhere near large enough to hold all this milk and "milk".
Your mom rose up and exited the room.
Tommy weakly gripped you as he nearly collapsed from exhaustion. You managed to catch him before he brought his face up and kissed you again. In response, you reached down and gave his softening meatstick a long slow stroke, making him moan.
Now that this is over, what will you do next?
