Chapter 1
He could still remember it as if it was yesterday. His first heat. He was in the past, training in the hyperbolic time chamber together with his father. His father from that time line who wanted nothing to do with him. No father-son bonding for him. The moment they stepped inside he knew he was on his own. When he woke up one morning three months into their year stay in the chamber feeling off he didn’t know what was going on. He never felt this hot in his life before.
10 years ago:
When Trunks woke up that fateful morning three months into their training in the hyperbolic time chamber he didn’t know what was going on. His mind was clouded and he felt like he had a high fever. The sheets were clinging to his body and some specific part had formed a nice tent under the sheets. He couldn’t suppress a moan when he sat up. Quickly, he looked over to the other bed but it was empty and looked like no one had slept in it. He let out a big sigh of relief that he wasn’t caught when he laid his head back on the pillow. His clouded mind was making up images of a good looking woman licking his erection. His hands slipped down to his hard cock. He brushed his fingers over it lightly while he imagined a woman doing that to him. The light touch was sending shivers up his spine. His cock gave a light twitch. He really liked to tease himself. It felt so good. He took the sheets between his teeth and bit down to suppress his moans. His eyes were tightly shut. The woman in his mind's eye was licking his shaft up and down. Pressing her tongue in the slit on top. He did the same with his thumb. The woman took his cock into her mouth and he let out a growl of appreciation. He started pumping his cock while the woman bobbed her head up and down over his cock. He could feel the pressure building, he was getting close. Quickly, as to not dirty the sheet, he kicked them off. His hand was rapidly pumping his cock. When he reached the edge he arched his back and sprayed his seed, coating his stomach with it while he grunted his release.
He got out of bed and made his way over to the adjoining bathroom. While he turned on the shower he looked at himself in the mirror. “What the hell?! I look like crap.” His eyes were bloodshot and he looked like he hadn’t slept at all. He rubbed his eyes and let out a sigh as he made his way into the shower. The cold water felt amazing on his feverish body. With one hand he reached behind him and grabbed the soap bottle. He squished a decent amount in his hand and placed it back into the rack behind him. Slowly, he let his hand slide over his body, starting at his chest and arms, making his way down. His cock was again standing at attention mode, hard and firm. When he touched his erection he let out a soft moan. He spread the soap over the head and pushed it down. Pleasure shot through his body. “What the hell,” he thought. “I thought I just took care of you,” He couldn’t stop touching it and his mind started to cloud over again. It felt so good. He placed his head against the cold tiles and kept on teasing his cock. With his other hand he made his way down to his testicles. Rolling them in his hand. He squeezed his eyes shut and tried to picture that nice curvy woman teasing his cock again. He picked up the pace. His breath was quickening. He felt the pressure build up, he knew he was getting close. He bit his lip to stop himself from almost screaming his release against the tiles. His legs felt weak. He turned around and slid down to the floor of the shower with the back of his head against the tile wall. It took a few moment before he got back from his high.
Still horny, Trunks looked down at himself. His erection was still there as firm as before his powerful orgasm. He moved to sit on his knees and touched himself again, starting with his nipples. The sensation sent electric shocks down to his cock. He moaned softly while he worked his way down his body. With his right hand he took a firm grip of his cock. With his thumb he teased the slit on the top. Pressing it in a little caused him to moan again. He started to stroke himself teasingly. He was so getting into it that he first didn’t notice the banging on the door. “If you don’t open the door now I will break it down,” his father yelled from the other side while he banged on the door again. “Well that killed the mood completely,” Trunks thought. “Just two more minutes” he yelled back. He finished his shower quickly, turned it off, and grabbed a towel. Putting it on his lower half, he hoped it would shield his father eyes from his erection that just didn’t seem to want to go down. He flared his ki to dry himself down while he opened the door to let his father in. “Hmpf took you long enough,” his father said while pushing him aside. He signed as his father close and locked the door behind him.
Back in the bedroom he dressed himself in his already torn cloths to start his training for the day. His erection felt very uncomfortable in his confinement. “Well it'll just have to do for now,” he thought, “it will go down after a while. I just need some distraction.” He ate some breakfast and left the living quarters for the open endless void of the hyperbolic time chamber. After a few minutes of flying, he thought that he was at a decent distance from the living quarters to start his training. He started by warming up, stretching all his muscles. But with every move he could feel the fabric of his boxers move over his, what looked like, permanent erection. Trying to ignore the feeling, he just kept going. Feeling he had warmed up enough, he used the mirror technique to make a clone of himself that he could spar with. He was so gone in his training that he forgot all about his morning wood. A few hours later when he decided to go back for some lunch he noticed that his cock was still standing at attention. “This is getting ridiculous,” he thought.
He got back to the living quarters. “Well, let’s just first deal with this problem,” he said to himself. He walked into the bedroom to get to the adjoining bathroom when he saw his father sleeping on one of the beds. His eyes ravaged over his father’s body.
“Gods, that body is sculptured by a god. Look at those abs and those thighs. I wish I could touch them. Make him sing for me,” he thought while he looked with lust in his eyes. “Wait a minute! What the fuck am I thinking?! I’m straight! Why would I think about a man like that, my father at that for crying out loud.” He whispered to himself in panic when he realized his thoughts. With a crimson embraced look on his face, he turned around and made his way into the bathroom.
What he didn’t know was that his father woke up the moment his son's aroused smell hit his nostrils. The smell that came off his son was overwhelming. Vegeta could pick out the smell of a Saiyan in heat. It was making him hard in an instance. “This is going to be fun,” he thought.
He got out of bed and made his way to the bathroom door. He opened it slightly. His son forgot to lock the door behind him. He peeked inside. His son was standing in the shower again. The smell of sex was in the air again just like this morning. He heard his son let out a frustrated grunt. He chuckled to himself, “yeah, that isn’t going down anytime soon, son,” he thought with an evil smirk on his face. Slowly, as to not startle his son, Vegeta made his way into the bathroom. He was really enjoying the show before him. His son was standing with his head arched upwards to let the water fall over him while he was jerking himself off again.
Trunks was so into it that he didn’t notice his father standing there. But he did notice when he felt fingers pressed against his tail scar. He released immediately just from the sheer pleasure it gave him. He had to grab the wall to steady himself. With big surprised eyes he looked at his father’s smirking face.
Vegeta saw the disbelieving stunned face of his son. It made him smirk, the overwhelming heat and sex scent was all around him making his cock twitch in his pants.
“F-father?”
“You’re going into heat. Is this your first one?”
“I think so?” Trunks replied.
“You’re going to need more than ‘just masturbating’, boy.” Vegeta closed the distance between them and sniffing along Trunks neck line. Pheromones assaulted his senses and the prince started getting aroused.
“Father! What are you doing?” Trunks pushed Vegeta away from him. His father’s intentions weren’t lost on him, and Trunks felt torn between giving in and resisting his advances. This was wrong, by human standards.
“Isn’t it obvious, boy? You need my help.” The Prince took the hand that pushed him away and pulled Trunks to him.
“You’re a guy. And my father…!” Trunks protested.
“Does that matter?”
“Among humans, YES!”
“You’re only half human. You’re also part Saiyan, and in the Saiyan culture sex is shared with family. It’s a learning and bonding experience.”
Vegeta pushed Trunks back to the shower wall putting both hands on the tiles locking Trunks in. He smirked at his son’s expression. The conflict that was going on in his mind was visible on his face. He lowered his head to his son’s neck and licked the spot where his future mate's mark would one day be.
Trunks gasped, his father’s actions sending shivers down his spine. His mind was still in conflict. He was taught that doing it with a guy was just disgusting and wrong specially if that guy was your father even if he was from a different time line. But his father smelled so good and the pleasure he gave him felt amazing that his instincts were winning from the moral thoughts.
Vegeta could feel that his son was on the brink of giving in and upped the stakes by pressing their lips together. With his tongue he licked those full lips. He smirked as he finally felt a response. Trunks opened his mouth to let his father's tongue enter and explore his mouth. He touched the intruding tongue with his own and moaned from the delightful taste. He wanted more of that and pushed his tongue into the awaiting mouth.
Vegeta ended the kiss looking Trunks straight in the eyes. He could see them radiating lust. It was almost overwhelming, Almost! Confident that his son would not try to escape him he started to explore the naked man in front of him. He pressed their mouths together again while his hands got to his son’s chest. Vegeta let his fingers slide over the nipples making Trunks moan at the sensation. Vegeta left his mouth and went on a quest down. Kissing Trunks skin all the way down to his nipples. He took one in his mouth and bit softly on it which caused Trunks to press his hard cock against his father’s erection, only the fabric of his father’s spandex pants separated them.
Those pants were starting to bother him. He wanted to feel his father's skin against his. He grabbed the rim of his father’s pants and ripped them off. Vegeta looked up at his son’s face he saw him smirking down at him. His son pressed their erections together causing both of them to moan at the touch. Vegeta grabbed Trunks' arms and pushed them next to his body against the tile floor while he kissed his way down dipping his tongue in his navel. Trunks was getting louder, he was so sensitive due to the heat that he felt the pressure building. He was starting to crave his father's touch. Not even in his wildest fantasies could have ever thought it would feel this good. It was like a door was opened to a part of him that he always ignored up to this moment in his life. He wanted to reach the edge, he was so close. Vegeta must have notice the desperate grunt that escaped his mouth. Vegeta licked his son’s cock from base to tip making his son release all over his father's face with a surprised yell.
Trunks looked down at his father's semen covered face. He could feel his face turn red. “OMG,” he thought, “who would release just before he is getting a blow job? Father must think I’m still a virgin.” His father just smirked at him and used his hand to wipe the semen of his face. He liked it off his fingers. “Damm, he tastes good.” Vegeta thought. He took his son’s still firm cock in his mouth all the way to the brim. He wanted to taste more of his son’s tasty juices. “Oh my GOD!” Trunks gasped out. His head fell backwards against the wall. His body was shivering from the pleasure.
Vegeta let go of Trunks' hand, placing them on his son’s hips trying to keep him from chocking him with his firm cock. He felt Trunks' hand taking hold in his hair. Making him bob his head up and down on that wonderful cock. One hand made his way to his son’s ass kneading the cheek in his hand. He heard Trunks gasp out again. He let his fingers slip over his entrance.
Trunks opened his eyes with a startle, pulling Vegeta off his cock by his hair. That just made it all too real. His human morals coming back to him. “This is wrong,” he said to his father. “Don’t you love my mother? We can’t do this, it will break her heart.”
Vegeta let out a sign and stood up. He grabbed his son’s face and forced him to look him in the eyes. “Yes” he said “I do love your mother.”
“Then we have to stop.”
“I love your mother,” Vegeta repeated, “but what we are doing right now, me helping you get through your heat, has nothing to do with my relationship with Bulma. This is just you and I. Human morals don’t apply here in this situation.” Vegeta licked a trail down to Trunks cock, “are you human, boy?”
“I-I’m part human.”
“Are…. You…. Human?” Vegeta asked again between every lick he gave Trunks cock.
“…No.”
“Good.” Vegeta got back to work on his son’s cock, and his fingers renewed their way teasingly to Trunks' entrance. This time, they met no resistance. He let his fingers swirl around. Getting a moan out of his son’s mouth every time he touched it fully on. He reached up to get the soap bottle and put some on his finger to ease his way in. Still with that delightful cock in his mouth he pressed his way in slowly stopping every time he heard his son grunt. When he was knuckle deep inside he held his finger there so Trunks could get used to the feeling. It didn’t take long before he felt him pushing back on his finger. He slowly pulled his finger out and pushed it back inside. This earned him a moan from his son. He repeated this until he felt the muscles loosen. He added a second finger and tried to open up that entrance for him, scissoring his fingers every time he pulled out. After a few minutes he added a third finger. Tasty pre-cum was now oozing out of his son’s cock into his eager mouth. With his third finger he tried to locate his son’s prostate. The moment he touched it, his son let out a scream releasing himself in the father's awaiting mouth, Vegeta swallowed everything up to the last drop.
Vegeta waited until he felt Trunks' muscles relax again to pull out his fingers while he stood back up. He pressed their mouths together. He scraped his teeth over his son’s swollen lips drawing a drop of blood from the scratch. Releasing his son’s lips he swirled the taste of Trunks blood around in his mouth. He grabbed Trunks by his hips and turned him around. Vegeta took a step back and took a good look at his son’s back. He let his eyes have a good look before he grabbed his son's tight ass and spread his cheeks apart. He coated his cock with the soap he used before and pressed the head of his cock to Trunks' entrance. He could already see his son tensing up. To get Trunks' mind distracted Vegeta let his thumbs ghost over his tail scar while he pushed himself slowly in until he was ball deep inside his son.
It was very hard to keep himself from just trusting inside that tight heat. Lucky for him it didn’t take long before he felt Trunks moving his hips on his own. Slowly he pulled out and pushed back in hitting Trunks' prostate.
Trunks didn’t know what was happening to him. Before this moment he would have never believed that having sex with a guy would feel this good. Every time his father hit that spot deep inside him he saw stars all around him. By now he was pushing back every time his father thrusted inside, moaning his approval. Trunks began to buck and quiver from the strength of each stroke. He could feel the pressure building again, getting him closer to the edge.
“Father! I..” he let out an other moan while he was trying to from words. “I-I’m about to…. To come” The words escaped from his lips.
Vegeta smirked at those words and gave one more well placed thrust to his prostate. He felt the muscles convulsing all around his girthy cock. The sensation made him release as well. He let out a loud grunt while he filled up his son with his seed. He felt that his son was struggling to stay on his feet so he lowered both of them to the shower floor.
Trunks' vision started to clear again. That was the most powerful orgasm he ever had in his life up till now. He was still sitting in his father’s lap with his back pressed against him. His breathing was slowly going back to normal. “Wow!” he said “That was just….” He just couldn’t find the right words.
“Yeah,” Vegeta answered. Somehow he knew what his son was thinking. He pulled his son closer into his embrace and let out a satisfied sigh. The both enjoyed the water falling on them, washing away the evidence from their previous activities.
Trunks' cock finally went limp for the time being. He felt too relaxed that he was on the brink of falling asleep. “Just give in,” Vegeta whispered into his ear. Trunks didn’t respond, he was already asleep. Vegeta stood up with his son in his arms, turned off the shower, and got out of the shower. With a quick flare of his ki he dried them both. He made his way into the bedroom were he put Trunks down on one of the beds. He looked at his son’s face and carefully brushed the locks that were sticking to his forehead away. He lingered there with his hand for a moment, really taking in his son’s face. He pulled back and dropped the blanket on top of him before he made his way to the kitchen. “Better get something to eat now,” Vegeta thought. He knew Trunks would wake up soon hungry for a Saiyan’s touch.
