Work Text:
Boruto was very irritated with his father…
It was New Year's eve but, as always, he didn't come back to dine with his family, too busy with his job as Hokage to even take care of his own children.
Since he became Hokage, it was always like that, his father was just a father in name, always absent for important events like their birthday. At most, he left a clone to 'be here' but it wasn't the same as being here…
Boruto couldn't take this situation any longer and decided to act to retrieve his father (even if it meant losing the Hokage).
He asked his friends for advice but as none of the proposals worked, he tried to ask his mother for his weaknesses but in vain…
He decided to barge directly into his father's office to talk with him but as always he was occupied and the boy was driven out of the office. He was so irritated that he decided to try mind-controlling drugs sold in a pretty beaten shop, recommended by Mitsuki.
That night, his father was sleeping in his office, too tired to return home after a particularly hard day. Boruto infiltrated the building and entered the office without a sound, like a proper ninja, but Naruto was not sleeping as deeply as Boruto thought, so he woke up from his sleep to see Boruto in front of him.
"What are you doing here in the middle of the night Boruto? I told you to go home!"
"It's your fault if I'm here. You are busy everyday and you don't even care about us so I'm going to drag you home, even if it's by force, for Himawari and Mom."
And like that he threw the bottle on the floor in the direction of his father. What both didn't know was that the bottle was a sexual mind-controlling drug.
Naruto, surprised by the reaction of his child, was delayed to react and breathed the drug in full.
"Yes, it succeeded! So now, come back home, father."
"Yes master, I will come." And like this Naruto stripped and started to masturbate.
Boruto was surprised at the reaction and 2 things bugged him: 'Why he stripped?' and 'Why is he masturbating?'.
He finally read a part of the instructions of the bottle, in his pocket, and it said: To have your own sex slave, this bottle is the best product to own. (This has a 1 week effect so don't use it randomly on yourself >_<).
As he read the contents, he was pretty confused but Naruto's voice excited him: "Master I came so what are we doing now?"
Boruto didn't know how to respond but his body wanted to have some fun apparently as he was harder than his kunai. His father's 19" dripping with cum was appealing but he didn't want to have a sex slave with a bigger dick than him, even if it was his father, but for the moment, he couldn't have the solution for that problem so, for now, he ordered his father to suck his 7 incher and to masturbate at the same time.
After being exhausted to the core by his stamina-idiot father, the night was almost finished and the office was covered in cum. He ordered Naruto to clean the office and to work as if nothing happened, to not arouse suspicions, and went back home, trying not to wake up his mom to not have to face her fury as he was out all night…
The next day, Boruto woke up sleepy but as hard as yesterday's night.
*I did all of these things yesterday to satisfy you and it's like nothing happened…*
He went to school, feeling tired from yesterday's events but excited about what he would do tonight. As he left his imagination and desires free, he didn't listen to the lessons which brought him some punishment but he didn't care and was fixed about tonight's events.
After school, he went to the drug shop and bought the size theft drug and a stamina booster as a solution for the problems he encountered yesterday. As he did not have as much stamina as Naruto, who had a lot more chakra with Kurama, he was utterly exhausted by yesterday's session.
He drank the stamina booster like an energy drink and waited for the night to go to the office where Naruto was waiting for him, as Boruto forbade anyone to come to disturb him at night except himself.
Boruto arrived and he told his father about the size theft drug, which has the effect of stealing the person who drinks the red part's cock size, but only if he's consenting, to the other person who drinks the blue part.
It can be stopped at any time by the person whose size is stolen, but with the mind controlling drug the consent was easy. They drank the bottle and stripped to see the effects live with a measuring tape in hand. The growth of his cock was synchronized with the shrinkage of his father's and as he was controlling Naruto, he could stop whenever he wanted. As his cock grew from 7 inches to 8, he felt like he was about to cum but wasn't able to so it was both painful and pleasurable. And it was far from being done as the growth amplified also his sensitivity along with the size. He also sensed an increase in libido.
Not thinking about the consequences, he wanted more and more so the cock grew to 9, 11, 14 inches… He was assaulted by a wave of pleasure and pain intertwined. But as he wanted to be bigger than Naruto, he wasn't done and the growth continued. As his length was at the 19" mark of the tape, he looked at the cock of Naruto to see his former size and he paused the growth for the moment to compare his former small size (even more on the body of Naruto) to his newly grown monster.
He thought it was very exciting as his new monster was now 1/3 of his height of 4'9", but he continued the growth to finally stop at 24" or 2'. On the other hand, Naruto's cock was now a pitiful 2", 1/12 of the new size of Boruto and almost 1/10 of his former size. It was ridiculously small compared to the monster Boruto was packing now. Of course, his balls weren't spared as the former baseball-sized balls were now the size of an acorn and Boruto's former tennis' balls were now coconuts.
As soon as the growth finished, the restrained pleasure assaulted him all at once and he came hard… So hard that he thought his cum would penetrate the ceiling as it flew with so much force it splashed off on the ceiling, raining down on them… After a minute or two, his cock stopped shooting but his cock didn't give any sign of calming down, even harder than before, it was ready for the second salvo.
After admiring his new size, which he couldn't do, he wanted to test the increased sensations. He ordered Naruto to suck his cock, but as his size increased greatly, the sensations were much more intense than expected, so he came really fast but harder than before and the cum production was almost 2 times as much as his earlier orgasm. His orgasm persisted for almost 5 minutes, covering the floor, Naruto and himself with cum.
He ordered Naruto to lick his body to remove the cum all over himself and, as he executed his order, Boruto admired the scene, his cock twitching with pleasure. When Naruto finished licking him, he ordered him to give him a blowjob, and to swallow all his cum. As he was trying to give him a blowjob (trying because the cock was too thick to enter in a normal mouth) Naruto, with the help of the Transformation Jutsu was taking the entire beast in his mouth. The sensation was too intense for the virgin Boruto as his cock's enhanced length was covered by the moisture and the hotness of Naruto's mouth and with his increased sensitivity, he was cumming before long, releasing volley after volley in Naruto's mouth.
He was like he was pissing cum as he saw Naruto's stomach gradually bulging with more and more volume, as he filled cum into it. After a few minutes and a considerable number of volleys of cum, he unsheathed his cock from his father's mouth, leaving him with a belly like a full term pregnant woman.
Boruto felt refreshed but his cock had a mind of its own as it was as hard as if nothing happened. Because of the combination of the increased libido and the stamina booster, his cock refused to go down, even after 3 mind-blowing orgasms. So Boruto decided to go all the way to satisfy his monster…
He ordered Naruto to be on all fours and to prepare his ass to receive his mighty beast. Naruto inserted one after one his fingers, voicing louder and louder moans with Boruto masturbating to the scene. He continued to prepare his ass until he could enter his whole hand inside, as his son's dick was now thicker than his whole arm. When his hand could enter, Naruto already came three times as, even if he was experienced in sex with women, he was still an anal virgin.
As he saw his father cumming, a thought floated in his mind: 'I want to see more of this face'. And as he finished preparing his ass, Boruto, without warning, plunged his cock into the hole well prepared to receive it but as his cock was much thicker than expected, Naruto screamed and moaned at the same time as his son's monster entered into his no more virginal ass and was rearranging it as its own. Boruto was halfway through when his father came for the fourth time. It was so intense that he didn't pay attention to his father and was focused on the sensation of flesh of his father's asshole, enveloping his length with a tightness, moisture and hotness incomparably better than his mouth.
Although he was only halfway through, he was almost cumming but, pridefully, he pushed his cock throughout the way to feel even more better and, as he was fully into his father, both were cumming, but the sheer intensity of Boruto's orgasm shamed his father's pitiful one, it was like day and night from before the growth.
Boruto's cum was pushing through the digestive system of Naruto, giving him a belly even bigger than before. He continued to fuck his father throughout the night and returned home to sleep for one hour or two, leaving his father the clean-up and to his job for the day.
The next morning, Boruto was very horny, even if he came at least 10 times that night, he was urgently in need to masturbate as his cock was painfully hard so he feigned a cold to rest home to play with his newfound monster all day, but with the enhancement and the stamina booster his cock refused to go down even after hours, giving him almost infinite sex drive and endurance…
But, as he continued masturbating, he found it was no longer enough for him and what he wanted was to have sex with his father as the sensations were unmatched compared to masturbation…
To be continued?
