That night Goten couldn't sleep, his mind just kept going over what happened during the day. He got to suck his fathers dick and eat his cum, then he licked Goku's ass hole and then ate more of his cum. Not to mention the fact that Goku said that he can keep sucking his dick as long as no one's in. His room would have been pitch black if it wasn't for the moonlight and the dull red glow of the alarm clock that layed on the desk. '02:11am' was displayed on the front of it. The sound of various animals filled the room. He looks over to see Gohan sleeping, one arm rested behind his head and the other draped among his stomache. Chichi wasn't home tonight because she decided to have a few drinks with Bulma and thought it would be easier to sleep at Capsule Corp. Goten got out of his bed and tip-toed his way to Goku's room. He slowly opened his fathers door, there on full display was Goku sleeping, completely nude and his ass facing the ceiling. His left leg was straight down and his right leg was cocked at a 90° angle, his hairy balls were visable between his legs. Goten moved closer to the bed and then climbed inbetween his fathers legs. Stairing at his dad ass and balls. He reaches out and starts stroking Goku's velvet balls. Goku's hips started grinding into the matress below.
"Yeah...." He says, still asleep. Goten moved down and parts Goku's ass cheeks, revealing the glorieous red ring surrounded by hair. Goten licks his lips then dives in, sticking his tongue straight into the hole and starts wiggling it about.
"Mmmmhh..." Goku moans, feeling the tongue up his ass. Goku starts squirming about to the pleasure but remains asleep. He then moves around too much, causing Goten's tongue to disconect from his ass as he turns over onto his back. Goten's eyes homed in onto Goku's erect pillar. His balls hang low, laying on the bed, covered in pubes. The hair led up to a full bush of black hair where the giant Saiyan dick stood, pointing straight up the the ceiling. The foreskin was slightly parted, letting the red head that was hidden below poke out a little. Goten had an idea. If he wouldn't do what he does to Chichi to him when he's awake then he'll do it whilst he's asleep. Goten takes his pyjamas off and throws them by the door. Goten didn't know that he would need lube but he did want to taste his fathers balls and dick before he rode on it. He lowers his head and starts sucking on the sack of skin with a hungry moan. He licks his way up the pole and engulfs the head whilst wanking him off. He slowly starts bobbing upand down. Soon, he gets bored and decides that now is the time to ride him. He lets the cock out of his mouth but still holds it.
"Here we go." Ge says as he stands up and turns around, his back facing his father. He knows Goku is a heavy sleeper but he didn't want to risk climbing over him until he's got what he came for. He lines the head of Goku's dick up to his tight, hairless ass hole. Soon, Goten was sitting on it like a stool, not penetrated yet but his ass was starting to part as the head was slowly but surely sliding in.
"Mmmghh!" He moans in pain and pleasure. He kept lowering himself until he finally felt it, the head was in.
"Ohhh." He squatted there for a few seconds before going down more and more until he could feel Goku's pubes tickling his ass and the large balls pressing up against his small ones. He sat there for about thirty seconds or so to get used to the feeling. 'Mom likes this?' He though, 'Well he was moving fast... maybe...' Goten started moving back up the length then plopped back down. Goku's rod went straight up, hitting just the right place for Goten.
"Ohh!" He let out a loud moan, he quickly coverd his mouth and sat still, trying to not wake his father. He repeated the process of going up and down the giant cock. The sound of his ass cheeks hitting Goku started to over power the sounds of the animals outside. 
"Mmmhh." He heard behind him.
"Goten? Wha- What the hell!" Goku half yelled. Goten foze in place for a few moments before turning around.
"I wanted to know what it felt like..." He spoke quietly, thinking he's in trouble seeing as his dad told him they couldn't do this. As he says this though he startes bouncing a little again.
"Ohh.... Kami you're tight!" Goku whispers through gritted teeth. Goku's large hands move up and hold onto his waste.
"It feels good daddy!" Goten moans. Hearing this just gave Goku permission to start lifting Goten up and push him back down on his dick. Goku started moaning more, he needed more friction. He scoots Goten up so that he could get on top, doggy style. Goku's large frame covered Goten's small one. Goku started plowing into his son fast and rough. The sounds of his skin hitting skin aggressively broke the air.
"Oh... Ohhh, fuck!" Goku yells, picking up the pace.
"You're soo fucking tight Goten!" Goku whispers into his sons ear.
"Ohh.. I- I won't be able to last much longer Goten." Goku said breathlessly.
"You're soo good!" He exclaims. Goten was in soo much pleasure too, the huge cock was slamming into his prostate.
"It feels amazing daddy! Can you go faster?" He asks as he's getting pushed forward with the force of his dads hips.
"Ohh.. Yeah!" Goku started picking up the pace.
"You want faster, huh?" Goku says. The room lit up with a bright yellow light, Goten looked up to see that Goku took on his Super Saiyan form.
"This should be fast enough!" He says, picking up the pace even more. Another twenty minutes or so go by of Goku slamming roughly into Goten.
"Here it comes Goten.... Uuuurgghghh!" He yells as his hips slow their pace and then he slams back into him one more time. Cum flies straight up Goten ass, filling it to the brim. Goku was panting hard as his dick was still in his son and small beads of cum trickled out his sons ass and down his balls. The glow of the room dims as Goku reverts back to his normal form. He slowly slides his dick out of Goten's full ass.
"Wanna clean this up for me?" Goku asks, pointing to his dick. Goten quickly turns around and starts cleaning Goku's cock and balls.
"Looks like your hard too, huh son." Goku says whilst laughing. Goten looks down and goes slightly red with him being soo much smaller than his father. Goten was on his knees still, trickles of cum started falling out his ass and down his legs.
"I know... Turn around for me again." Goku says excitedly. Goten does as his father says. He feels Goku's hand push his torso down so he's in the doggy position, then he feels his fathers warm tongue lick up the trickles of cum then dive into his used hole.
"Ooh..." Goten moans. Goku reaches round and starts jerking Goten off. Goku's tongue was lapping up all his cum from Goten's ass. Goku and Goten were moaning the entire time. Goten didn't last long before spilling his seed onto his fathers hand and the matress below.
"That was amazing dad!" Goten says, truning back around.
"You're hard again!" He says as he bows down and sticks the huge cock straight into his mouth.
"You're amazing..." Goku moan.
"Do that to daddys ass again Goten." He says roughly. Goku goes onto his back and lifts his legs enough to get Goten's head under to lick his ass. Goten had the best sight of all, Goku's large cock and hairy balls right in his face then further down his red ring. Goten dove straight in, licking from his balls down over his gouch then straight into his ass hole. One hand playing with the large rod and the other massaging the hairy nut sac that rested on his nose.
"Fuck... I'm cumming again!" He yells. Goten kept going, knowing he was making his father feel good.
"Urrgh!" Goku almost screams as he covers his rock hard abs with his creamy jizz. Goten removed his tongue from Goku's ass then licked all the cum from Goku's pubes, up his treasure trail then all the cum that layed on his abs and pecs. Goten fell asleep ontop his father, both exhausted and naked. In the hallway stood Gohan, fully naked and quickly pumping his cock, his balls bounced below as his hand started playing with them.
"U-uugh!" He moaned quietly as he faced his dick towards himself, spilling his own cum on his chest and abs as he watched his brother clean their fathers cum.
