Ben 10: The Wild And Crazy Days Of Summer
by Andrew Troy Keller (firstname.lastname@example.org)
My name is Ben Tennyson and I was just a 10-year-old boy who was going with
his grandfather named Max and his cousin named Gwen on a cross-country road
trip for the summer in a replica of a GMC Classic Motorhome known as 'The
Rust Bucket', which he had modified with advanced technolgy after he had
served his tour of duty with 'The Plumbers', which was this government
organization that was based beneath Mount Rushmore and assigned to deal
with extraterrestrial, paranormal and other situations that many others were
unable to handle.
But of course, that was before we had stopped at this national park for
the night, which was where I had found a strange alien device known as the
Omnitrix and only thought of it as just a fancy-looking watch but when I had
made the mistake of putting it on my wrist, I had shockingly discovered that
I was unable to get it off.
But that was not the only thing that I had discovered, for as soon as I had
hit the 'face' of the Omnitrix, I had suddenly noticed that it was able to
transform me into ten different alien creatures and it had suddenly became
so cool to me that I had decided to use the powers of those aliens to become
And to tell you the truth, it was a good thing that both my cousin Gwen
and Grandpa Max were able to discover my little secret and decided to help
protect the entire planet Earth against all fomrs of sinister threats such
as this octopus-faced type creep known as Vilgax, who had once squared off
against my grandpa during his Plumber days and is now cooling his heels off
in a prison-like dimension known as the Null Void.
But of course, as soon as I had already used all ten of the aliens in the
Omnitrix--which Gwen, Grandpa Max and I had named Diamondhead, Fourarms,
Ghostfreak, Grey Matter, Heatblast, Ripjaws, Stinkfly, Upgrade, Wildmutt
and XLR8--on some of my adventures and also discovered some new ones, I had
suddenly began to wonder what else does the Omnitrix have inside of it.
But I was unable to do it right away and the reason for that is because
Grandpa Max was still driving The Rust Bucket with both Gwen and me inside
of it and if I were to try experimenting with the Omnitrix and force it to
change me into something that should be considered -- let's just say --
non-human friendly, he was going to freak-out in front of Gwen and use one
of his Plumber weapons to blast me straight to freaking hell.
And it was because of that little piece of logic that I had decided to wait
until Grandpa Max stops at another national park and steps out of The Rust
Bucket for something, which was exactly what he had done at this one national
park within the state of Montana.
You see, it was at that very national park that Grandpa Max had parked The
Rust Bucket at one of the park's campsite and spotted one of his old Plumber
buddies doing the camping-out bit with his family, which had caused me to
turn his smiling face towards both me and Gwen and say, "Okay, Kids. I'm
going to step out and go say 'hi' to an old friend for a little bit. So,
could you kids please do me a favor and keep yourselves out of trouble while
And after the both of us had looked at our grandpa straight in the eyes and
said 'okay' to him, Grandpa Max had stepped out of The Rust Bucket and walked
himself over to his old Plumber buddy and Gwen had started doing some dumb
and boring thing that girls her age would always do.
Anyway, as soon as I had looked out of the window and noticed that both
Grandpa Max and his old Plumber buddy had welcomed themselves back into each
other's lives with open arms and started talking about all the old times that
they had together, I had started rotating the selector of the Omnitrix and
kept on doing that until I had finally discovered there was this one blank
spot inside of it.
But as soon as I had lifted up my hand and placed it over the blank spot of
the Omnitrix just to get a closer look at it, that stupid cousin of mine had
stepped out of the bathroom, placed herself behind me and asked, "What the
hell are you doing with that watch now, Stupid?"
Of course, that had caused me to slam my hand down on the Omnitrix and have
the both of us become engulfed in a room full of this strange bright glow,
which had lasted for only a minute until it had finally disappeared and
caused both Gwen and I to discover that the bright glow has transformed us
from a pair of ten-year-old kids to a pair of full-grown adults.
And as soon as she had finally realized who had caused that latest mess,
Gwen had looked at me with angry eyes and growled, "You stupid idiot! Do you
realize what would happen if Grandpa would come back here and discovered what
we had become and it was because of you fooling around with the Omnitrix?"
"Well, it wouldn't happen if you -- for once -- stop yourself from spying on
me!" that was what I had said to my very own cousin, who had looked at her
newly-transformed self, placed her hand on her forehead, took a deep breath
and said, "Oh, this is just freaking great!Now, I have to go change my
clothes! I hope Grandpa's sweats would be able to fit me!"
And as soon as she had gone into the bedroom to start looking around for
Grandpa Max's sweats, I had taken one more look out of the window and
discovered that he was still having a great time visiting with his old
Plumber buddy and had became unaware of what had happened.
And after I had let out a sigh of relief, I had gone into the bedroom in
order to apologize to Gwen and explain to her why I was fooling around with
the Omnitrix, only to have me discover that she was standing bare-ass naked
in front of a large mirror and staring at her newly-transformed body just
before she had started pumping two of her fingers in and out of her hot, wet
pussy and began carressing her own tits with the other hand.
And then, after I had stripped off all of my clothes and began stroking my
stiff cock right there and then, I had moved myself closer to my unsuspecting
cousin and placed my hand on her bare back, which had caused her to turn
herself quickly around and look at me like she was about to ask, "What do you
want now, Ben Tennyson?!"
But just as she was about to say a single word to me, both Gwen and I had
looked at each other's wonderfully-built naked bodies for about a minute or
two before we had kissed each other ever so passionately on the lips and I
had started licking all over Gwen's nude body -- all the way down to her hot,
moist snatch and carressing her firm breasts.
And then, after she had placed her hands on my bare shoulders and said,
"Aaaahhhh, yeeeessss! That's it! Do it, Ben! Touch me! Touch me there! Suck
my wet pussy dry! Aaaahhhh!" both Gwen and I had laid our nude bodies down on
the bed and I had turned myself around and allowed her to start sucking on my
stone hard dick, which had caused the both of us to suddenly realize that
even though we were two ten-year-old kids stuck inside adult bodies for God
knows how long, Gwen and I were able to experience the one thing that we had
never experienced with each other before, for we were both experiencing pure
and untamed erotica... and enjoying every minute of it.
Just then, after I had placed my stiff cock inside Gwen's asshole and used
each of my hands to carress both her stiff mounds and hot and steamy cunt, my
own cousin has placed one of her hands on my bare shoulder and the other hand
on my bare arm and yelled at the top of her lungs, "AAAAHHHH, YES!THAT'S IT!
DO IT, BEN! TOUCH ME! FUCK THE LIVING SHIT OUT OF ME! MAKE ME WANNA CUM!
And then, after the both of us had started moving ourselves harder and faster
and our lovemaking has also arrived at that very same national park, both
Gwen and I had finally came and collapsed due to exhaustion and fell asleep
with our naked arms in a lover's embrace.
Just then, as soon as Grandpa Max had came back inside The Rust Bucket and
saw his two ten-year-old grandchildren palying a nice and quiet boardgame
(and becoming grateful that the power of the Omnitrix had finally worn-off
and changed us back to our normal selves before he had came back), he had
let placed his gentle hands on our shoulders and said, "Well, I was wondering
when this was going to happen and I'm glad that it did happen."
And after he had given the both of us a gentle pat on the head and went into
the bathroom, both Gwen and I had let out a sigh of relief that our own
grandpa was unable to figure it out and decided to just chalk-up what we had
experienced -- as our adult selves -- as only just one of the wild and crazy
days of summer.
