The jounins of Konoha were walking over the Hokage Tower because Tsunade had called them over to talk to them about something. "What would Tsunade want us to do now?" Genma asked, as he yawned. All of them expect for Asuma had shook their heads no, but Ibiki had noticed that Asuma didn't do anything when Genma had asked the question. "Asuma." Ibiki started and Asuma looked over to him with eyes any of the jounins could describe what he was feeling at the moment. "Are you okay?" Ibiki asked and Asuma just smiled and shook his head yes. When they made it to the Hokage Tower, and walked inside of the office, they all saw Senju Tsunade and Shizune holding a paper.
"Good." Tsunade started. "You all are here." She said while.she got up from her desk and walked in front of all of them. "Tsunade-Sama, No one else here have a sibling, or anything here according to the paper." Shizune said while she read the paper carefully when he was walking up and went by Tsunade's side "What else does the paper say Shizune?" Tsunade asked and Shizune read the paper out loud. "Any Clan of any sort, either have a sibling, cousin, nephew, etc,"She said while she continued on reading. "Must practice incest at all cost." Shizune said as she finished. All of the jounins eyes went wide and looked over to Asuma, while Asuma, himself was also shock, but he was blushing.
"So you're saying that," Ibiki started while he and Asuma made eye contact with each other, then they look back at Tsunade. "Asuma has to have sex with Konohamaru? His nephew?" Ibiki asked while Asuma blushed at the thought of Konohamaru, his nephew fucking him. "Yes but it's only this one time, unless he gets addicted to it, which can happen to some people when they practice incest for the first time." Tsunade explained while Asuma blushed even more. When they left, Asuma went to go pick up Konohamaru from the academy. It had been days since his father Sarutobi Hiruzen had died due to his student killing him. It hurted Konohamaru the most, and Asuma had offered to moved back into the Sarutobi Compound to take care of Konohamaru, and to look after him. After he moved back in, him and Konohamaru had gotten closer during the past few days.
Asuma stood outside of the ninja academy for Konohamaru to come, normally he would smoke a cigarette outside, but after what Tsunade has said, he thinks he couldn't even pick up a cigarette after what he heard. He then saw Konohamaru running out of the academy and over to him. "GET BACK HERE KONOHAMARU!" Someone had yelled from the inside, and coming outside of the academy. Konohamaru then ran into Asuma's arms, holding for dear life, when Asuma felt this, he hold back a moan, and cross his leg to try and get rid of the wanting something rock and hard like a cock to inside his ass, especially Konohamaru's. "What happened?" Asuma asked as he hold back his moans when Konohamaru had tighted his grip around him.
"Well Konohamaru here tried to snuck out of class." The teacher at the academy explained as Asuma looked down to Konohamaru. Konohamaru then looked and chuckled nervously. Asuma sighed and apologized to the teacher for Konohamaru's actions, the academy teacher appreciated the apology, but he thinks Konohamaru should be the one to apologize not his uncle. Asuma understood and him and Konohamaru walked off going to Sarutobi Compound. When they got there, Konohamaru then went to go take a shower, and Asuma also then but he went to bathroom in his bedroom. When they both got done, they ate dinner, but Konohamaru had noticed that Asuma had looked like he wanted to do something, but he knew it was wrong. So when he saw Asuma walk into his bedroom, he decided to walk behind him.
When Konohamaru had gotten inside of Asuma's bedroom, he saw Asuma strip his clothes off, and sit on the bed. He blushed when he saw his uncle's body. Konohamaru then walked up behind Asuma and grop his ass which Asuma moaned at and turned his head behind him to figure out who did it. When he turned his head around, he saw Konohamaru gripping his ass, and he blushed. Asuma then picks up Konohamaru, walked over to his bed, and placed Konohamaru down on his bed. Asuma then told Konohamaru to take off his clothes, which Konohamaru was confused at but he did what his uncle told him to. When he was done, Asuma then went up to Konohamaru, and began to lick and suck his cock. Konohamaru was shocked at this and moan. "U-Uncle." Konohamaru started and Asuma looked up to him with hearts in his eyes. "W-Why are you doing this?" Konohamaru asked and Asuma took Konohamaru's cock out of his mouth. "We have to practice incest, Lady Tsunade said so." Asuma siad while he continues to suck and lick Konohamaru's cock. Konohamaru moaned louder.
When Konohamaru had climax, Asuma was shocked because Konohamaru didn't warn him about it but it did like the taste of cum inside of his mouth. When Konohamaru had finished cumming inside of Asuma's mouth, he pulled out of Asuma's mouth and panted for air. When he looked up, he saw his uncle get in doggy style and he blushed. "Come Konohamaru and fuck me." Asuma said while Konohamaru walked over to the other side of the bed where Asuma was, got on the bed, and positioned his dick to Asuma's entrance. Konohamaru then positioned his cock to Asuma's asshole, and having his hands on his uncle's hips,and pushed it inside, groning at how tight his uncle's ass was, and how his uncle's ass was clutching over his penis.
"Oh my fucking god! It's so huge and thick!" Asuma yelled as he gorned and moaned in pain and pleasure. Konohamaru then pulled out of Asuma's ass, and turned Asuma over to his back, and Asuma was confused. Then Konohamaru positioned his cock to Asuma's asshole, and pushed it inside, and began to thrust inside of Asuma, not giving his uncle enough time to adjust to his penis size. Asuma moaned loudly. He didn't care if the whole village could hear him and his nephew having sex, it was the most happiest time of his life. They went on for another minute or so in that position before they switched again.
This time Konohamaru was on his back while Asuma was riding his penis screaming loudly as he felt his nephew's huge and thick penis go up inside of his ass. "Ugh! Oh god! How is your penis this huge and thick!" Asuma yelled as he moaned and closed his eyes while Konohamaru giggle led at how his uncle was being at the moment. 'Lady Tsunade! How could agree to this!' Asuma thought as continued riding Konohamaru's cock, and he felt something hot, and sticky fill his ass. 'Konohamaru cummed inside of me didn't he?' Asuma thought while he gorned as he pulled off of Konohamaru's dick, and went to get tissues so that he could get some of the cum that was in his ass out, and he could go take a shower, but Konohamaru grabbed his arm, and Asuma looked Konohamaru with confusing eyes but then his eyes widened when he saw that Konohamaru's penis was hard and was ready for another fuck session.
Konohamaru then pulled Asuma back over to the bed, and Asuma sighed while he got in reverse cowgirl position with his legs by Konohamaru side. He then pushed Konohamaru's dick inside of his ass, and began to ride his penis again while this time Konohamaru was licking and sucking his nipples while Asuma thought this was weird because no one had done this to him before and Konohamaru is the first person to do so. "K-Konohamaru." Asuma said while he muffled his moan by biting his lips. Konohamaru looked up to him. "Don't tell you l-like this?" Asuma asked while he moaned loudly. He couldn't believe that Konohamaru was liking having sex with him.
Konohamaru didn't respond, but he began to thrust upward inside of Asuma, which Asuma thought it was really uncalled for, and Konohamaru then kissed Asuma, french-kissing him. Asuma was shocked by this but he kissed by, moaning into the kiss as he let Konohamaru do the thrusting for now as he moaned. "U-Uncle I love you!" Yelled Konohamaru as he went faster and harder with his thrusting and Asuma began to mon out of control. Asuma's eyes went wide when Konohamaru had cummed again inside of his ass again. 'I hope Konohamaru is done.' Asuma thought as he pulled off of Konohamaru's dick for the second time, but this time Asuma had saw that Konohamaru didn't let him go.
This scared him a little because he thought Konohamaru wasn't going to like having sex with him at all. "Uncle I want to have sex with you until morning." Konohamaru said while he positioned Asumain another position and began to fuck him until Asuma was either mind broken, drooling of pleasure, etc but he didn't think about that. All he thought about was his uncle begging for him to go faster and harder inside of him.
Meanwhile Kakahi, Might Gai, Kureani, and Iruka had just came from the bar, well they all didn't drink, but the other jouinins did, and they were walking over to Kakashi's apartment to play a game. When they walking over to Kakashi's apartment, they heard noises from the Sarutobi Compound, which is five blocks away from Kakashi's apartment. Kureani, Kakashi, and Gai were shock but Iruka was confused.
"You guys don't think that Asuma is actually having sex with Konohamaru do you?" Kureani asked while Kakashi and Gai nodded while Iruka's eyes had went in shock. Why would Konohamaru and Asuma be having sex if they're uncle and nephew? Why is this supposed to be happening? He had questions that needed to be answered and fast. "Yes it seems like it Kureani." Kakashi said while he was chuckling as well as Kureani and Gai. "And it looks like Asuma isn't the one doing the fucking, it Konohamaru." Kureani said as she chuckled at the thought of Asuma's face.
"What do you mean Asuma and Konohamaru are having sex? Aren't they uncle and nephew? Iruka asked while Kakashi, Kureani, and Gai laughed. "Apparently clans that have a sibling, cousin, etc, must practice incest and by the looks of it. Konohamaru may be getting addicted to it more then Asuma." Kakashi explained while Iruka's eyes went even more widened when he realized that one of his students is fucking his uncle.
"Why don't we go look inside and see what Konohamaru and Asuma are doing." Said Kureani as she dragged Iruka with her, Kakashi, and Gai walked over to the Sarutobi Compound. When they got closer, they all went over to the window that was to Asuma's bedroom, and looked inside. By the looks of it, Asuma didn't have any curtains on his bedroom window so they could see and hear everything that was going on inside, and also the walls inside of the house was thin so they could hear the moans that Asuma was making while he was being dominated by his nephew.
Konohamaru was lying on his back while Asuma was riding his cock and he was moaning and drooling of pleasure, and Konohamaru had his hands on Asuma's hips as Asuma rode his cock. "Uncle I think you like riding my penis." Konohamaru said while Asuma was moaning and throwing his head back as Konohamaru's dick had hit certain places inside of him that he didn't know that Konohamaru could reach.
"Your cock is something else Konohamaru. I never knew it was going to feel this good." Asuma said while he moaned louder when he felt Konohamaru cum inside of him, for the sixteenth time. Konohamaru then pulled out of Asuma and began to thrust inside of Asuma while holding Asuma's leg as he pounded into his uncle, and Asuma had his head on his head and was using his other arm for support to hold him up.
They french-kissed each other, and when the kiss was over, Konohamaru thrust harder and faster inside of his uncle, and this caused Asuma to moan louder than he ever did before as he kept his grip on Konohamaru's head.
Meanwhile outside of Asuma's bedroom, Iruka was blushing hard after what he just saw, while Kakashi and Gai had a nosebleed and was asking Kureani for a tissue. Kureani chuckled and give both Kakashi and Gai a tissue so that they wipe away the blood from their noses. After Kakashi and Gai wiped their noses from blood, everyone that was outside of Asuma's bedroom had left and going over to Kakashi's apartment for a game night. They all decided that they should invite Asuma to the next one because he busy right now.
After Konohamaru and Asuma was done with their sex session, they both decided that they should take a shower in the morning, because Asuma's legs hurt and he didn't feel like getting up out of his bed, and Konohamaru didn't want to go take a shower by himself, so he waited until the morning to take one.
Asuma just couldn't believe that he just had sex with his nephew. He just couldn't believe that he had to practice incest, and he would be wrong if he said that it was good, but it was good, and he wanted to continue having sex with Konohamaru. He doesn't care if Konoha or other villages would give him weird looks, he would continue having sex with his nephew and there's no one stopping him from doing it.
And with that Sarutobi Asuma went to sleep, while he couldn't wait until tomorrow to come, he just couldn't wait for Konohamaru to fuck him again. He threw goes to sleep, thinking about how this is going to be the next level in his and Konohamaru's relationship and he's ready for it.
