Ryuk got ready for bed after a long day. Ryuk was in the washroom brushing his teeth and looking in the mirror seeing a light brown furred dog with black hair and black ball tail, Ryuk spit out the toothpaste and rinsed his mouth out. He turned off the light and got into bed instantly falling asleep. Overnight Ryuk tossed and turned in his sleep, scratching his balls then shaft, as the night passed his genitals would give the sound of stretching while they would grow inches and heft by the hour. The sun rose and birds chirped loudly as they were conversing with each other forcing Ryuk to wake up. He yawned and stretched but as he did that his pajama pants and underwear creaked and ripped opened, feeling confused but didn’t think too much about it and got dressed, even realizing that his pants became tight which made him more confused but coughed it up to he is growing wider. He got his shoes and heard voices outside as he went to look he saw his friends and waved then went to the door and locked up before meeting up with them outside. They all greeted each other with high-fives and went off into the main streets and entered in the arcade they always go to.

Ryuk and his friends went to the counter and bought a bag of coins for the machines, paid for them then ran into the giant room filled with arcade games and other type of games. Ryuk went to Pac-Man first, put two coins in and focused on the little yellow dude and the dots, staying away from the ghosts till he needed the power-up to eat them. While he was flying through the levels with ease he noticed he had to scratch his genitals a good bit but never really thought why as his cock and balls throbbed and stretched in his tight pants, his balls growing more in size and getting heavier, producing more sperm by the hour. His cock stretched longer, became fatter. Ryuk felt his face get hotter and bit his lower lip, his eyes started to play tricks on him making the ghosts in the Pac-Man game to get a full human body with a fat ass and Pac-Man would also get a humanoid body with a fat huge veiny cock, he would go after the ghosts and pounced on them, mate pressing every ghost and fill them up his spunk. Ryuk stepped away from the machine and left with a blushy face with one of his friends looking at the screen and seeing a normal Pac-Man game with Pac-Man running into a wall till the game over screen came up. Ryuk went to every machine with the visuals of every character for their respected games were breeding each other making Ryuk to run out of the arcade, walking back home he looked down at his stretched pants seeing a massive wet spot on his crotch and touched it and sniffed his finger being relieved that he didn’t pee himself.

Ryuk walked into the apartment and wiped the sweat off his face, he moved into the living room to sit and relax as well as watch television but when he turned around the wall he saw his dad on the couch sleeping and snoring with his ass in the air. That sight made Ryuk pant and his cock throbbed making the barely holding on pant stitching snap and fling his cock out at full mast and dripping in pre-cum. Ryuk walked to his dad and yanked the pants to his ankles and climbed onto the couch, he then placed his new massive cock between his dad’s ass cheeks and thrust slowly, rubbing his cock flesh on his dad’s ass flesh till he couldn’t wait and shoved half his cock deep into the warm ass and moaned lustfully. Ryuk stood there gripping at his father’s ass and gave a massage, feeling the slight softness of the ass grinding along his own cock. He slowly thrusted in and bit his lower lip, gave the ass a nice slap which made him surprised none of what is happening is even waking up his dad. Ryuk smiled putting both feet on the ass cheeks and climbed up, reclaiming his balance and he thrusted faster making sure he hits the base of his crotch and bulging Jair’s belly out, Ryuk could feel the couch from inside the flesh of his dad’s body which is making Ryuk drip saliva from his mouth onto the back, he moved his hips faster his balls flying into the air and slamming against the cheeks. Ryuk throws his head up and lolls his tongue out panting and grunting, Ryuk not going easy on his dad’s ass he was aiming to mark and claim it for himself.

“T-take it you slutty father~”

Jair’s eyes slowly open from the rocking of his body and the moment he became fully conscious a flood of abdominal and anal pain flow through his body and he screamed loudly, trying to get his son off him but Ryuk got a lot heavier with their new genital size. Ryuk didn’t pay attention to his father’s scream of pain and kept thrusting wildly into Jair’s anus. Jair grips his paws into the fabrics of the couch and biting into a couch throw pillow, blushing like hell but also in so much pain. 

“S-son please st-stop you a-are hurting me”

Jair was begging and pleading to his son but Ryuk was not letting off, he just kept going harder and harder, holding onto the back rest of the couch and Jair’s hip to keep his balance. A loud plapping emitted into the apartment complex Ryuk showing his dad who the real man of the place is with the rough intercourse and the ignoring of the whining pleads, he gave that ass another swat leaving a red paw-print shape mark on the right cheek. Jair couldn’t handle how rough his kid was going on him, his vision started to go, his belly feeling raw and his anus was burning. 

“Dad! Im gonna c-cum~”.

Jair was too weak at this point he couldn’t do anything and before he could speak he passed out while Ryuk went faster and harder till his pre-cum turned into thick warm cum, flooding his dad’s insides and bloating that belly. After Ryuk was finished he plopped onto the couch, his cock pulled out and settled between Jain’s cheeks and slightly pumped out tiny splurts of cum onto the back. Ryuk sighed in relief and grabbed the television remote and put on a show.

Both Jair and Ryuk slept on the couch together while Jair woke up and shakily walked to his room and got ready for the day. When ready he looked over at his son to see him still sleeping and walked out of the apartment for the day. As the hours go by Jair felt weird and off, feeling confused on what his body is feeling, he had no choice but to go on with his day then he felt eyes stare at him and as he looked around he saw many pair of eyes just looking at him, mainly a bit lower down on him, so he followed the glances and saw his chest popped out with small supple breasts which made him quickly cover up and in embarrassment he ran into a public bathroom, pulled off his backpack and took out a sweater he would put it on to cover up and hopefully hide them from the public, Lair then went to the urinals and opened his pants and pulled out his dick and in shock with a panicked demeanor he rubbed and pulled at his dick seeing it baby sized. Now being more confused and in horror on why his body is changing like that he slapped his face cheeks to snap out of it. He decided to finish his day up with more staring, but he didn’t know why others are still looking, so he followed his body with his paws but nothing new popped out. He just decided to ignore it and try to not pay any attention to the eyes. But than he guy came up behind him and slapped his ass hard as they passed and Jair grabbed his ass from the pain then came to realization that his ass grew three times it size and he now has a dump trunk. That was his last straw and quickly got what he needed to get done and headed home for the night, quickly as he made it home he put everything away and ran into his room to hide in his blankets.

The next morning Jair got out of bed and walked to the kitchen to make breakfast, he took out eggs and bacon and began to fry them humming to himself completely forgetting what happened yesterday. Ryuk came out of his room stretching and yawning, scratching his thick shaft and walked into the kitchen to the fridge to grab a glass of milk, when he put the milk back in he notices his dad’s body. Looking intently at him and feeling his cock trying to break free Ryuk slapped and gripped his dad’s ass and went in, wrapping his free hand around Jair’s wide hips and reached into his pants.

“Wow dad~ Your dick is so damn punny and look at your tiny breasts~”

Ryuk started to fully violate his dad’s body gropping, squeezing and rubbing everywhere till Ryuk pushed his dad onto the floor.

“Look who is the real man now you sissy baby dick! Why don’t you be useful and worship your sons cock like a bitch you are!~”
 
Ryuk proclaimed as he whipped his dick out and jerked off in his dad’s face, moving a lot closer where his sweaty cock firmly presses against Jair’s cheek, lathering the puff of flesh in sweat.

“See dad you were born to worship your son, now choke on it!~”

Ryuk grabs his dad’s head and his own cock and shoved the thick shaft deep into his gullet and started to thrust in and rape that tight dad throat. Ryuk lolled his tongue out feeling that throat grind against his shaft, Jair’s saliva coating every inch like nothing, forcing some to fly off in every direction. “gulp” “glek” “slurp” Jair was being used like a bitch but he couldn’t do much since his son was strong, and he was a shy weakling, so all he could do was take it and slurp down the shaft. Ryuk pulled at his dad’s ears to pull him further down his length as Ryuk thrusted and gripped harder and with the sheer tightness of his dad’s passage that he cummed pretty fast. Ryuk pulls out and covers Jair’s body in thick cum before taking the food that was cooking and went into his room to relax and eat. A couple of hours later Yampi came home with his mom greeting her lovely son as he put his things down and hugged her tightly.

“Yampi honey how was your stay at your friends”

“It was good mom, we chilled, gamed, and enjoyed each others company for the past couple days!”

Yampi smiled and took more steps into the apartment seeing a huge mess of white stuff in the kitchen. The mom went to the couch and sat down while cuddling up to her husband that was still covered in thick layer of cum. Yampi looked confused on why Jair looked like that and all of a sudden Ryuk bolts behind him and tackled him to the ground, ripping off Yampi’s clothing. Ryuk can see his step-brothers bright yellow and white body as he licks his lips and Yampi looking scared and confused, wondering why his brother did that. Ryuk grabbed his cock and looked toward their mom, seeing her get pantless and start playing with herself Ryuk went ahead and shoved his hyper cock into Yampi’s ass making him squirm and yelp from pain. Ryuk took some pleasure in giving his brother anal pain, so he didn’t go easy at the beginning like he did for their dad and rammed to his base, his cock hitting the floor withing the belly of Yampi.

“M-mom! Help me!”

In pain, he looked over at his mom even seeing her enjoy what Ryuk is doing to him as she was shoving her fingers fully into her vagina. Ryuk fucked harder with more velocity, balls slapping him rough leaving red marks on Yampi’s thighs. Ryuk grabbed Yampi’s neck and brought his face up to his with a lustful grin seeing Yampi’s face all teary, he thrusted faster as well as made their bodies straight up giving the parents a view of the massive abdominal bulge constantly popping in and out. 

“You, you like that Yampi you dirty dog!~”

Before Yampi could open his mouth Ryuk covered it with his hand to keep him quite, ramming his cock into Yampi. Ryuk’s cock throbbed every couple of thrusts making a small load of pre-cum burst into the yellow belly, Ryuk lolled his tongue in bliss ready to cum deep and overfill his step-brother to his absolute limit.

“H-hope you hungry you yellow cumdump!~”

Ryuk bites into Yampi’s neck as Yampi’s fit slim body pudged out while Ryuk unleashed massive ropes of cum by the second. After a few ropes went in Ryuk’s paw got slimy as cum poured out of Yampi’s mouth making Ryuk grip tighter forcing his step-brother to swallow it down.

“Yampi dear, Ryuk is the man of the house now so if he says you are his cumdump than that’s what you gonna be”

The mom giggled after those words and pulled her fingers out as Ryuk pulled his cock out leaving Yampi on the floor with a cum gushing asshole. Ryuk went into the kitchen grabbing a cup of orange juice and relaxed on a seat drinking his drink.
