All of that day Goku could only think about what Trunks had done, he didn't know if Goten had told him everything or if he was just curious. 'He must have told him!' Goku thought as Trunks knew exactly what he liked. Goku was worried, Who else had Goten told? He thought.
The next day Goku was home alone, Chichi had gone out shopping and Gohan and Goten were out training. Goku was sat at the dinner table, wearing only the bottoms of his orange training gi. His large, bulging muscles were on full display to the room. He was about to go upstairs when he heard a knock at the door.
Goku made his way over to the door to find Trunks stood there.
"Hey Goku, is Goten there?" He asked, not knowing that Goku had figured out what had happened.
"Erh... Why don't you come in." Goku replied, not wanting to say yes and lie but not wanting him to leave either, he had to get to the bottom of what happened.
Trunks made his way inside and sat on the settee in the living room. Goku had no clue on how to approach the situation,
"Goten's out training with Gohan at the minute, they should be back soon though." He said, this however was a lie, Gohan and Goten had only left about ten minutes beforehand so they were going to be a while yet.
The thought of Trunks on his knees quickly came into Goku's mind as he stood in the doorway watching Trunks. His cock started to swell up.
"Would you like a drink or something getting?" Goku asked, trying to get out the room.
"Yes please, just water." Trunks replied, staring at Goku's bare chest. Trunks had to put a pillow over his lap to hide the fact that he was getting hard. Whilst Goku was in the kitchen his raging boner wouldn't go down. He tucked it into his waistband before going back into the living room.
"Here." Goku said as he handed the glass to Trunks. Trunks started drinking, whilst his head was tilted Goku decided to take this opportunity. He dropped it trousers the floor and stepped out of them, his hard cock bounced as they dropped.
"How'd it taste?" Goku asked, slowly wanking his painfully hard dick. Trunks thought he was talking about the water but in reality he was talking about his cock and cum.
Trunks put the glass down before turning his head towards Goku.
"What the!?" Was all Trunks said before Goku interrupted him.
"I know it was you in my tent, not Goten." He said as he slowly made his way over to Trunks.
"Me and my dad do it too! He says almost all saiyan men did it with their sons as some sort of bonding ritual!" Trunks panicked and blurted out. Goku was shocked that not only did most saiyan men do it but the fact that Vegeta does it with Trunks. The thought of Vegeta and Trunks together made Goku extremely horny.
"Why don't you get naked and help me out with this then?" Goku said, still tugging on his cock. Trunks wasted no time in stripping out of his clothes. His small dick bounced as Goku's did when he stripped out of his clothes. Goku's eyes were fixated on Trunks' hard rod, he noted how it was bigger than Goten's and had a dusting of purple hair around the base.
Goku sat down the couch and spread his legs, causing his large nut sack to rest on the couch cushions below. Trunks got onto the settee and quickly engulfed Goku's large cock. Trunks' mouth was stretched to the limit at the girth of Goku's cock, it was much thicker than Vegeta's and only slightly shorter. After about ten minutes Trunks' nose was finally touching the wiry mass of Goku's raven pubes. As his nose touched them Goku decided to give him a helping hand and push his head down so his nose was now buried in them.
Goku was letting out large moans and Trunks' eyes started to water. Trunks started to play with Goku's balls, rolling them around in his small hands. Goku was getting even more into it, he started stroking Trunks' back and playing with his nipple. Goku made his way further back until he was stroking Trunks' round ass. Soon, Goku's fingers found Trunks' hole and started to tease it.
As Goku made his way into Trunks' hole, Trunks could feel Goku's cock start to twitch in his mouth, he knew exactly what was coming. A flood of hot white saiyan spunk filled Trunks' mouth, making him choke a little. As Trunks started to choke on the cum he lifted off Goku's cock whilst he was still cumming, causing Goku to cover Trunks' face with his cum.
Trunks' face was now covered in thick white ropes of cum. Goku sat there and laughed at the young saiyan, his cock was still hard and Trunks was definitely still horny. Trunks got up and at on Goku's lap, the entrance to his hole was pressed up against Goku's cock as he slowly lowered himself. He was facing Goku as he slid down the large cock. Trunks' face was still covered in Goku's seed.
Goku pulled his hand up and wiped some of his cum off Trunk's face, feeding it to him as he bounced on his lap. The last glob of Goku's cum didn't go straight into Trunks' mouth though, instead Goku put it into his own before passionately kissing the younger saiyan, swapping Goku's thick load between them before Trunks swallowed it.
Goku was now thrusting deep into Trunks as he started to feel his balls tighten.
"I'm gonna cum again!" Goku yelled as Trunks kept bouncing as he was thrusting. Seconds later he unleashed his second wave of cum, even though he had came not too long ago his second release was almost as big as the first. As the started to get dressed the front door opened. Before being seen, Trunks quickly escaped through the back door.
