Trunks layed on his bed, his room lit by the moonlight. He kept his ears open for any noise, waiting for his father to come in and use his ass hole again. The thought of his fathers hard cock made him fully erect within seconds. He couldn't wait for Vegeta's third load of the day.

He kept the but plug in his ass, holding Vegeta's seed in all day, just like the prince of all Saiyans had asked him to. He could feel his Vegeta's cum in his ass as he layed there, slowly stroking his cock to the imaginary image of his fathers long, thick, uncut cock.

Trunks layed there, looking at the ceiling with his cock pointing straight up. His ears peaked as he heard footsteps in the hall and then the handle on his door slowly start to turn. He covered himself up and slipped under the covers in case it was someone other than Vegeta. The door opened to show his father, stood there in some speedo like boxer shorts. His large bulge on full display, he was clearly already hard.

Trunks moved his covers off of him and showed his own cock off to Vegeta. Vegeta's mouth slightly arched, smirking at his son's eagerness.  Vegeta walked in and closed the door behind him. He made his way over to his son's naked body on the bed, he stopped by the bedside cabinet and turned on Trunks' lamp, filling the room with a dim light.

Vegeta stood back and spread his legs slightly, Trunk's eyes were glued to his father's concealed package.
"Come on then boy, it's not going to suck itself." Vegeta said quietly. Trunks wasted no time and hopped off his bed, his eyes never leaving his father's bulge. Trunks pressed his face up against Vegeta's crotch, feeling the large cock twitch against his face. He opened his mouth band started teasing Vegeta through the cotton prison of his boxers.

Soon, Trunks couldn't wait any longer, and neither could Vegeta. Trunks grabbed the waistband and quickly pulled it down. Vegeta's cock sprung straight up, slapping his son's face with a meaty slap.  Vegeta let out a small audible moan as this happened. Vegeta's cock pointed straight at his son, the tip slightly touching the lavender haired saiyan.

Trunks wasted no time in putting the mighty prick inside his mouth, engulfing as much as he could. Soon though, his nose was buried in Vegeta's trimmed bush and his chin was pressed up against the very balls he came from. Vegeta also sped it up a bit, thrusting his hips into his son's eager mouth.

Vegeta grabbed the back of Trunks' head and started face fucking him, making him gag on his cock. His balls slapping against his small chin, filling the room with noise. 
"Mmmm... Yeah! Suck your fathers cock!" Vegeta almost yelled as he violently fucked his sons face. Trunks kept sucking, humming on the meaty length that was in his mouth. 
"Finger my ass boy!" Vegeta said quickly before returning to moaning. Trunks reached under Vegeta's balls and spread his father's ass cheeks apart with two fingers before digging his middle finger into the tight, pink ring of muscle.

Trunks' finger slipped all the way in his father's tight ass hole, burying it til his hand stopped at the round globs of ass cheek. Eventually, Trunks added another finger in Vegeta's ass, fitting two fingers in. Trunks could feel Vegeta's dick twitch in his mouth. H e reached up with his spare hand and started playing with Vegeta's balls, rolling them between his fingers as he massaged them.

Vegeta grabbed Trunks by his hair, getting rougher with his new sex doll and started to pull on the purple strands, dragging his head on and off his cock until he slammed his hips forward and dragged his son's face into his pubes. He unleashed a large flood of hot saiyan cum into his son's mouth, filling it and his stomach.

Vegeta let Trunks clean his still hard cock as he held his head in place. Trunks swirled his tongue around the thick rod that was in his mouth, lapping up all of the creamy saiyan seed that gave him life. Vegeta slowly slid Trunks off his dick until it was completely out of his mouth.
"Turn around, I want to see my cum in your ass. You'd better not have removed your new... Toy." Vegeta said as he turned his son around.

Trunks ass now faced Vegeta. Vegeta could clearly see that Trunks has kept the but plug in. He kneeled down and pushed Trunks onto all fours as he did so. He grabbed the two round cheeks and spread them even more, showing off the flat base of the but plug.

Vegeta massaged Trunks' ass before gripping the but plug with his fingers. He twisted as he pulled it out, more and more of the small rod part showed itself before the round head came out, coated in Vegeta's spunk.
"Here, clean this for me." He leaned over and fed the but plug to Trunks who quickly shoved it in his mouth and sucked all the cum off.

Vegeta looked back down at his own seed leaving his son's ass, he couldn't let it go to waste though. He leaned down and started licking Trunks' ring, cleaning his ass from all of his seed. Vegeta's tongue swirled and licked as much of his cum up as he could, doing his best to clean Trunks' ass. 
"I think you've earned a reward for being soo good Trunks..." Vegeta said as he cleaned the rest of his cum up.
"Yeah?" Trunks said, not feeling his fathers warmth behind him now.

Trunks' turned his head towards his father, only to see two round mounds accompanied by a low hanging ball sack beneath. His eyes widened as they locked onto his father's tight ass hole, surrounded by black hair.
"You can fuck me Trunks for leaving that in all day." Trunks could see that Vegeta was wanking himself off as he displayed his ass to him.

Trunks wasted no time in getting behind his dad and lining his small cock up against the hole. He slowly pressed his head in and started thrusting, his purple pubes soon pinning against Vegeta. It wouldn't be long 'til Trunks came and they both knew it. Vegeta was quickly wanking his cock as he was getting fucked by his son.

Vegeta could feel Trunks' movements get stiffer and stiffer until he felt the cock in his ass twitch, without warning Trunks unleashed his hot seed into Vegeta. This just turned Vegeta on even more. He pushed Trunks out of him and got onto his back spreading and lifting his legs, showing his used ass off to his son.

Vegeta kept wanking his cock, his balls bouncing up and down as he did so.
"Don't just sit there, clean up your mess." Vegeta said in a playful tone. Trunks dove straight in and started cleaning the mess he made of his fathers ass, cleaning up all his cum. Vegeta kept wanking off until he could feel that most of the cum was gone.
"Fuck! Suck my cock now! I'm gonna cum!" He yelled at his son as he grabbed him by his hair, dragging him down on his cock and pinning him there, forcing Trunks to eat all his cum, not that Trunks was against it.

A large wave of cum erupted from the prince's cock, even larger than the one before. It quickly filled  Trunks' mouth, some came flying out the sides and landed on Vegeta too. Trunks did his best to keep all of it in his mouth, some still sliding out of the corners. He gulped down the ocean of cum in his mouth, loving the sweet taste of his fathers cum. He then leaned down and started cleaning the cum out of Vegeta's hairy legs, treasure tril and shaved bed of pubes. Not to mention the but of cum that somehow managed to get onto his chiseled abs.

They both layed there for a while, breathless. Vegeta had to go now though or he would have attempted another round, but he couldn't have Bulma finding him in their son's room, naked. He walked over to his speedo like boxers before he bent down, showing his ass hole off once more for Trunks.
"Remember, no-one can know about this... Not even Kakarot's brat." Vegeta hastily covered himself up and left the room, leaving Trunks naked and alone in his room.
