Goku got in the shower after a long hard day of training, water ran down his chiseled body and into the drin. After getting out the shower he realises that the only towel in the bathroom was a face towel, too small to wrap around his body, it barely coverd his junk and pubes. Goku has never been shy of his body and his naivety made him never understand why people should cover up. He quickly got dried and walked out the bathroom to see Goten stoon there, eyes stairing straight at Goku's crotch.
"Wow! It's really big daddy!" Goten gasped as he moved closer.
"And theres hair all over it!" Goku didn't know why people shave their pubic hair, hair is just hair.
"I know when people get older they grow more hair on their legs and arms but not on their weiners!" Goten was so excited seeing his father nude.
"Yeah, you'll have some in no time." Goku said, smiling.
"Can I touch it?" Goten said, moving his face closer to Goku's groin.
"Erm.. I dont know if that's a good idea-a-a!" Goten decided to reach forth and grab it.
"You have more skin here than I do dad!" Goku was never circumcised, neither was Gohan but Goten had an accident when he was younger. Moving his hand all around his fathers groin, intrigued at the differences, Goten brushed Goku's pubes and played with his foreskin. Quickly Goku's blood started pumping south, casing his dick to erect.
"Wow... It's getting bigger!" Goten has never witnessed something soo fascenating in all his life. Goku's mind started racing, his Saiyan blood was taking over, he needed to cum.
"I guess you don't know about the birds and the bees then..." Goku moaned as Goten shuck his head.
"It's how babies are made, when a man loves a woman they have sex..." Goten decided to reach under and ay with the large orbs conceiled in their sack.
"That feels soo good..." Goku's breathing started getting heavier.
"Boys can have sex too... If you want to try it." Goten's face lit up and he started laughing.
"Is it food?" He looked up to his fathers face as he played with the dark pubes that hung from Goku's balls.
"No no... You just play with daddy's weiner... But, differently to what you're doing now." Goten looked back down to the forest of hair and at the fleshy one eyed rod that looked back at him. The head of Goku's dick was exposed from under its skin blanket.
"Yeah!" Goten shouted, geting more excited by the second. Gohan and Chichi were out shopping and with the ammount of food that Saiyans eat Goku knew they'd be a while yet. 
"Come into the living room and sit down near me." The walked to the living room, Goku's cock swayed left and right with every step. Goten's eyes didn't know if they should look at the dick or Goku's fine ass. Goku sat down on the sofa and spread his legs, letting his balls fall down and rest on the seat as his dick stood straight up.
"Okay now son, you just need to grab it and move your hand up and down."
"Okay daddy!" Goten kneeled down infont of Goku and did as his father instructed, his eyes were fixated on the purple head poking out of the skin as he wanked off the man that gave him life. Soon the sound of Goku's wet foreskin filled the room, along side the smell of pre cum.
"What's this daddy?" Goten says as he swipes Goku's slit, picking up a bead of pre cum.
"I'm not sure, all I know is that it happens before a guy climaxes." With that Goten decided to put his finger under his nose.
"It smells weird..." As he says that he puts his finger in his mouth and tastes his fathers pre cum. Goku was amased and shocked that his son just did that.
"How'd it taste?" Goku asked. As he asked Goten swiped another bead and lifted his arm up for Goku to taste.
"I liked it." Goku moved forward and licked the finger.
"Yeah it's not bad..." Goku looked down at his son kneeling and wanking him off, stairing at each bit of pre cum that came out.
"You know son... You can taste more if you put your mouth over the top of my weiner."
"Like this?" Goten moved forward, engulfing Goku's cock head and continued to wank him off.
"Oh Kami yes! Just like that!" Goku's hips started to rock back and forth.
"Use your other hand and play with daddy's balls Goten!" Goku almost screamed. It has been months since him and Chichi had sex and he was dying for a release, not knowing he could have a wank, he always though you needed two people. Goten's hand reache under and started massaging his dad's balls, Goku's hands came down and started moving his son's head up and down.
"Oh god I'm close!" Goku yelped. His balls started to raise, getting closer to his impressive rod.
"Do you want daddy to finish in your mouth?" Goku asked with no intention of cumming any other way.
"Mmmhmm..." Is all he heard and all he needed. The vibrations just made it fell better. Volleys of cum flew into Goten's throat, not knowing what Goku meant when he said 'finish' He didn't really expect it. Goten's eyes opened as he tried to drink as much of his dad's cum as he could but there was too much. He moved off his cock and got showered in cum, soon it ended and Goten swallowed what was in his mouth.
"Sorry there was soo much son, it's been a while..." Beads of sweat fell from Goku as his chest raised up and down quickly.
"It's okay daddy, it tastes really good." He says as he whipes as much off his face he could and put it straight into his mouth. Goku's cock was slowly deflaiting but Goten wanted more, so he reached out and started playing with it again.
"You can't play with it yet, it's too sensitive." Goten's face dropped.
"Aww!" He tried to get more cum into his mouth when he sees some resting on Goku's ball sack, so he leans down and sucks the large orbs clean from sweat and jizz.
"You can't tell anyone about this, okay Goten? This has to be our little secret." Goku says as he stands up to get dressed.
"Okay daddy!" He says back with a smile.
"You need to go shower, you smell like semen." Goku laughes walking back to make sure Goten showers and to get dressed.
