This is what happened when me and woodsgal got bored. We made an awesome fanfic of course :P
Ben: *After eating a whole jar of pickles again*...I don't even like pickles *stares at empty jar and shrugs*
Omnitrix: *bleeps*
Ben: Huh...what's going on with the omnitrix...*fiddles with it*
Omnitrix: *glows blue and warm for a few moments* bleep, pregnancy test positive.
Ben:...WHAT...oh shit, Gwen's gonna kill me
Ben: Oh no, oh no, oh no pregnant...what do you mean pregnant....
Kevin: *Walks in* Hey Ben, why the long face?
Ben:...errrr nothing *eye twitches*
Kevin: Ben, you're lying...I can tell...what's up?
Ben: Umm alien business you wouldnt understand. *eye twitches again*
Kevin: Stop lying to me Ben, whats wrong? *notices blue omnitrix* Hey why's the omnitrix blue?
Ben: I have no idea *eye twitches*
Omnitrix: Bleep, I'll tell you once more then! Pregnancy test positive.
Ben: Damn you omnitrix! You're supposed to be on my side!
Kevin: Pregnant...you mean one of your alien's is pregnant again?
Ben: *hopes so* must be.
Kevin: So uh which one?
Ben: I dont know *asks omnitrix* ergh stupid thing why wont you answer me
Kevin: Hahaha maybe that night we you know....*trails off *
Ben: Nah not possible i'll ask the omnitrix for a DNA scan of the baby
Omnitrix: DNA scan complete *scan shows 50% of bens genes 50% of kevins*
Ben and Kevin: Oh shit Gwen's gonna kill us....
Ben: Right...so what are we going to tell people?
Kevin: I don't know...I mean, this is odd even for you Tennyson
Ben: *scoffs* It takes two to make a baby you know.
Gwen: *walks in* Baby? What are you two talking about?
Ben: Nothing much, we were talking about...Tiny
Gwen: *sighs* okay
Gwen: *Sees the empty jar of pickles*...Ben, you ate all the pickles! What are you pregnant...again?
Ben:No...don't be stupid *nervous laugh*
Bens eye twitches again....he realises and looks away.
Gwen: Hey Ben i saw your eye twitch whats going on I though Necrofriggian only give birth every 80 years. What is going on...
*no one answers*
Gwen: wait Kevin this has something to do with you I know it otherwise you would have cracked a joke...in fact lately you two have been much closer now someone tell me whats going on!!!
Kevin: Nothing's going on Gwen, Jeez we don't know what's going on either, It's probably one of Ben's other aliens.
Ben: We were just trying to work it out before we asked you.
Gwen: ...Kevin, I swear to god if you've done anything to my cousin...
Ben: Ha ha, it's not like that *eye twitches but had kept head turned*
Gwen: Fine, well we better get some research done...c'mon let's go ask Grandpa
Ben: Sure *is sighing in relief on the inside*
Later on in Kevin's car...
Gwen: So Ben what's actually wrong is one of the aliens pregnant again..
Ben: Umm I dunno Gwen stop asking...
Kevin: Yeah Gwen stop worrying 'kay it's not a big deal
Gwen: Ergh what's with you two anyone would think it was you guys having a baby..
Kevin and Ben: Hahahahahaha yeah right...crazy...
Gwen: Hmm you two are still hiding something and im going to find out.
*Gwen decides to try and read Ben's mind but is about to give up when*
Ben's mind: oh man what are we gonna do if Gwen finds out Kevin and me had sex
and I got pregnant she's going ot kill us.
*Gwen recoils from Ben's mind and shouts* YOU TWO HAD SEX!!!!!!!!
Ben and Kevin: *Both look at eachother and think Oh shit*
Is this the end or not?
