Welcome to Boxer & Rice

His dad was training--when was his dad NOT training?--Goten was with his girlfriend(s), Gohan was doing whatever a Saiyan with glasses did, Pan was out with Goku hunting down the ruined dragonballs and he, Trunks, Super Saiyan and Super Genius, President Of Capsule Corp was--
Laying on his bed. Naked. Staring up at the ceiling. While his hair dried. (Just gotten out of the shower and all. Hated to put his clothes on before he was completely dry.)
And because he was naked, and bored and male and saiyan--his mind drifted to happy naked thoughts. Thinking back to all the many times he had seen Goku naked, and his hand that had been on his stomach (the other behind his head) drifted downward. Twitched against his skin until he felt himself stiffening, and he let his eyes close, thought more happy naked thoughts--

"You're thinking of Goku aren't you?"

He opened his eyes and tried to sit up by there was a hand--a naked hand--against his chest that pushed him back down and he was looking up at himself?

Had he just learned Tien's technique and forgotten to remember it? He couldn't split himself off into other people. And there certainly wasn't another one of him lying around--naked.

"Who are you?" he demanded. (And finally remembered to move his hand off his erection. But only because he needed it to push the look-a-like back. But the look-a-like did not move.)

"I'm Trunks," he said. Smirked. "I would have thought you knew that." Then he looked down between them, at his erection and dragged his eyes back up to his face. "We masturbate a hell of a lot don't we?"

"...I don't know what you're talking about."

And this other Trunks just smiled at him. An arrogant sort of condescending look that he would have attributed to his father. The sort of look that he, the real Trunks, just did not make. He was a genius, he did not have to be arrogant to be a genius.
His eyes drifted down, over the identical face, his neck, to his chest where there were scars that he had never gotten (so he didn't split--who was this guy?) and like a moron he ran his fingers over the scars, felt the little indent of the new skin. Followed the little scars down, over the stomach, past his navel and stopped when he realized that he was feeling up a mysterious naked twin.

"Just who are you?" Trunks demanded again.

The answer he got was a much-put-upon sigh. "I'm you. Sort of. I came from an alternate future to help defeat Cell and keep Goku alive. Mom had to tell you about it--or someone."

He shook his head. "Sorry."

Trunks shrugged. "Doesn't matter. Now, back to thinking about Goku..." And there was a perverted little smirk on his face, a private sort of grin. Insinuations that he--the fake Trunks--had any comprehension of what he--the real Trunks--was thinking about. (Never mind he was right.)
"Oh, don't give me that look. I'm you. When I jack off I always think of Gohan or Goku." And he rolled his eyes at him.

Trunks sat up, shoving the fake twin back.
"Look I don't know who you think you are buuauuuuuuuuuuuuuuaaaaaaaaaaaaaaaaaah!"

The bastard curled his hand around Trunks' erection and slipped his hand between his thighs, right where leg met hip and was rubbing him. Pressing all the right places, leaving him helpless and clinging to the other Trunks. Panting and sweating all of a sudden--mind blank and mouth hanging open. And the jerk was just smirking. Like he was so much better.
So Trunks closed his mouth, leaned back, curled his fingers into his non-twins' pale ass and pulled him forward, so their erections rubbed together and pressed one of his palms against the tail scar on his back, brought the other around to rub his nipple.

And look at that mister-future-boy was panting helpless too. Hands tightening and moving with more purpose and urgency on Trunks, but he was jerking between the two hands on him.
Just like him. So maybe the liar was telling the truth. Maybe he really was from the future and maybe he really was Trunks himself. He was willing to take a little on faith (just as long as that hand kept doing its wonderful thing.)

The other Trunks moved the hand away from his thigh, leaned them back until he was against the bed and then he was kissing him. Kissing HIM!

This was--no, not incest. They were the same person. This was masturbation.

"Now," the future version of himself said. "Lets go get Goku."

"No--" Trunks said. Licked his bruised lip and looked up at (himself) Future boy. "He's just a kid--and he's got Pan, and there's dragons and--"

"He's horny."

"What?"

Trunks gave him one of those condescending time smirks again, and moved his hand away from his erection (which throbbed pitifully at the removal of such a hand) and the other boy pulled back, stood (naked) at the end of the bed and looked at him.

"You can stay if you want. But I'm going." He picked up his pants and shoes and jacket off the floor, pulled it all on and moved toward the window. Turned back to see Trunks getting his pants on and grinned.

"Bring the lube--we're going to need it."

By the time they finished the flight over the frigid sky (it was dark outside now--strange but--okay) they found Goku sitting outside a nice little hotel-type thing in a city that wasn't destroyed yet. He looked up at them. (Child. Child. Child.)

Both of them.

Blinked. Then had a huge genki grin on his face. "Trunks!"

And he actually hugged this boy from the supposed future.
(What was he doing here again? --Right, on a midnight mission to go see Goku to have sex with himself and the tiny version of the world's strongest warrior.)

"I never thought you'd come back." (That was unexpected.) And then the little blue-clad kid jumped on future boy, knocked him to the ground and sucked on his face.
(He'd seen Goku eat--this was a lot like that.)

And Trunks set them back up and rubbed his head, Goku turned looked up at him and smiled in the most fiendish, evil, conniving, 'I'm-so-going-to-fuck-your-ass' way. It was an incredible look for an eight-year old face. He felt a twinge of uncomfortableness that was completely outdone by the wave of lust that overtook all the other 'what the fuck?'ness of the moment. Then he turned back to look at future Trunks and ground his round little bottom right down against the boy. Leaned forward and said something to him that made future Trunks laugh.

Then they stood up.
"I know just the place!~" Goku said and he took off happily.
"What--You've done this before?"

Future Trunks blinked at him like he was a moron. "Yeah." Then went after Goku.
They found him outside of the city, in a crater (oh--that used to be a shadow dragon) stripped naked. He grinned at them when they showed up and future boy stripped down right to his skin. No problems.

"Oh, come on, Trunks," Goku said. Looked up, tipped his shoulders back and curled his hands into fists. He didn't even have to scream, he just burst through the levels of Super Saiyan until he got to four and then he looked at him, gold ringed eyes and the hair--perfect black hair. Smirked at him then and spoke with the voice that Trunks remembered. That still made him twitch in his dreams.

"You don't have anything I haven't already seen on him." And he pointed at the the future Trunks.

This logic was true. And his father taught him that logic should prevail in every situation. Therefore, he stripped as well, and tossed the lube (that Trunks demanded he bring) to the other version of himself and Goku and the other version of him grinned together. Had some sort of silent communication, and then he was attacked. Being kissed by himself (weird.) Big hands against his skin, strong (damn strong) body against his back, tail wiggling between his thighs, parting them as the strong hands moved down, over his hip bones, pulled his legs apart and Trunks (himself) moved between them.

Oh, and the monstrous erection against his back too. And the one (not as monstrous but intimidating) against his own. He whined between kisses, felt the teeth and the suction on his shoulder and rocked back and forth between the two of them, fully realizing that he was helpless--and that he was okay with that helplessness.
Definitely beat a night of masturbation.

Then fingers against him, down there--slipping into his body while the mouth still sucked on his, and the hands pulled his legs up farther, pulling his knees wider apart and giving the fingers pressing into him more room.

"Do you want to stop?" Goku asked him, right in his ear, so he could feel the lips moving, the tickle of his hair, and he jerked his head away from the other of his selves, and licked his lips, looked at Goku. Put his hand on him, in his hair, felt his back twisting as the fingers drove deeper and shook his head.

"No." Kissed Goku. So much energy. He could feel all that power, and it was paralyzing. Amazing. He slipped between the two of them. They were so hot, and he was drenched in their sweat and his and he reached his arms back, wrapped them around Goku's shoulders and held onto him as the other version of himself dropped down to his knees and continued to thrust his fingers (three now) into him as he tilted his head to one side and licked him. Lapped at his erection and then licked his lips and looked past him at Goku.

"You, him, me?"

Felt the nod behind him. And his legs were let down.
"Suck on his chest," Goku said in his ear. Made him shiver as he realized he was going down, falling to his knees, being drawn back to this future/alternate self and the legs (just like his) parted around him, pulled him closer and Goku's hand was between them, around his erection showing him how to move his hips and then he was pushed--inside.

Inside of future boy.

Hot and slick and--he kept blinking. That was all, fell to his elbows and pressed his face into the sweaty chest and blinked for his ability to retain reason. Heard the chuckle from future boy and heard Goku's knees hit the ground behind him. Pull him out of Trunks just enough that he was at the right angle. He clenched his teeth, felt the pale fingers on his ass, pulling him open and then--Goku pushed into him.

Stretching his body out, making his back tighten up and he pounded the ground, felt the instinct to fight rising and snarled, jerked between the two of them and Goku was driven further into him. Stretching him farther. Making him panic, but they both moved, Goku's arms around him, and Trunks' arms around him. Holding him still and kissing him. Purring or trilling or making their little noises, petting him everywhere. A mouth on his--his mouth on his--and hands in his hair, hands on his chest and his stomach, and Goku was inside of him all the way now, he felt the hips against his ass, and the Trunks in front of him nodded, leaned back down.

So he swallowed hard and Goku leaned down over him, so he was trapped on his elbows between them again. He moved a little, forward, into Trunks and felt Goku sliding out of him, pulled out, felt the stretch as he slid back in.

Whined, because something--something. Suddenly it was hard to breath and he couldn't explain the way his stomach clenched or the spots behind his eyes. Only knew what he could feel.

Aching, throbbing, heat, almost painful need to move. So he thrust into Trunks, centrated on the body that quivered around his, the inside of him that was hot and wet and the eager sounds he made as he slapped his hips up against the thrusts. Wanting more. And he moved more, felt Goku move in him, driving into him and doing something. Making the ache worse, making him want more of that too. He leaned back against the chest as he thrust hard into Trunks under him. Felt the fur on his, saw the pink-red tail flip between him and Trunks and wrap around the erection.

He drove his hips faster, everything felt everything--it tickled and it hurt and it felt like he was going to break, spiraling higher and higher and he was shaking so hard he couldn't do anything, didn't want to do anything because suddenly he was terrified that if he just kept moving, if he just moved his hips a little more and jerked a little harder back against Goku that was going to break.

He didn't want to break.

He whined and tried to stop, but the two of them were moving him now. Stronger than him, driving his erection into Trunks under him, and fucking him from behind. The sound of Goku saying his name--the sound of that voice, purring with pleasure like it was, strong heat inside of him, buried in his body--that hardness, and the voice and he felt it shatter inside of him. Light and heat and energy exploded out of him, and they held him again, kissed him, petted him. Mewled their little whatevers and he kissed them and nodded and pulled away from them to lay on his side and curl up. Exhausted. Blinked and watched.

Goku grabbed the future boy by the hips, hauled him back, rolled him onto his knees and thrust into him. And kept moving, thrusting into him as Trunks made his sounds, echoed back everything to him. Goku's name and nasty little things, and harder and Goku was jerking the boy forward with every thrust of his hips. Tail wagging in the air, sweaty and smelly and shining. Face twisted up primal and teeth bared. Gold eyes looking down at his conquest as he drove himself into Trunks until the two of them came with a cry loud enough to wake the dead all the way in Otherworld.

They collapsed and attacked one another again, ripped at skin and hair and kissed and came down from their high with the same energy they got there with. Goku rolled onto his back and he was the kid version of himself again.

"That's so pervy," Trunks (he, not the future one) said sleepily. "You're just a kid."

"Better get back to Pan," Goku said (like everything was normal.) "And you guys better get back too. Wouldn't want someone to come looking for you." A wave and he was gone.

"Care to explain that?" Trunks asked, got to his feet unsteadily and stumbled and limped his way over to his clothes. The other version of himself was still laying on his back.

"Not really."

MT: O.o!
Trunks: ...*so scared*...
Goku: *sniffle* Having two versions of Vegeta's son is still not as good as having Vegeta.
Vegeta: HA! *has a victory shag*
Once again--Happy Holidays!
