So here's the deal. I can't decide how I want to continue my story; so I decided I'm going to write two versions of chapter three(one involving aliens, magic and sex change, and the other being much darker and involving rape and murder), and whichever you guys like more, I'll continue from. Sound cool? If not, you can suck it because it's what I'm doing. Without further ado, the lighter version.
Ch 3: Goin' Hero
"Come on Gwen! You know we hardly ever get any alone time. I miss having fun."
"I know." responded Gwen calmly. "But we can't take chances. What do you think would happen if Grandpa saw what we were doing?"
This silenced Ben. They both feared being caught, since society viewed what they did as wrong. "Fine. But tonight I'm gunna sneak into your shower by 'accident'"
"That's just fine Benny." said Gwen with a wink. She loved performing for Ben. Though in honesty she missed having sex with Ben. It had been a few months since their weekend of experimentation and fun, and the time had taken its toll of both of them. They loved having sex and since they couldn't do it very often, they missed it very much. But whenever they did get to do it, it was very, very steamy and fun for both.
"I'm back." Grandpa Max announced as he walked through the side door of the RV.
Gwen let out a sigh of relief knowing she made the right choice and saying no.
WEE-OHH. WEE-OHH. They all knew what this sound meant. The RV was sensing an alien presence somewhere near. Grandpa walked to the front and sat down at the steering wheel. Immediately a GPS spun out of the dash, showing the best route to get to the alien. Max sped off after it as Ben and Gwen were both flung into the back of the RV.
After five minutes of driving they arrived at the scene of the alien. A giant dog beast alien creature was tearing apart a local park. Max recognized it. It was the same creature that was the cause of the special plumber trip those few months ago.
The door to the RV flung open and Ben jumped out as Four-arms and lunged on top of the beast, wrestling the alien to the ground. Then using his four arms he picked the beast up by all its legs while Max walked out and put special restraints on the legs that forced them together so it couldn't move. Gwen than walked out of the RV with the null-void gun and opened the portal. Ben tossed the alien into it.
"Easy enough." said Ben with a laugh, being pretty proud of himself.
The portal closed as Grandpa said "Kids get in the RV. I have to call a special plumber gathering. If ones here again, than it means an army is coming."
Both Gwen and Ben got into the RV as instructed. Normally Ben would have argued, but he could see that his grandfather was pissed.
"You know what this means right?" Gwen asked with an unusually large smile.
"What?" Ben asked completely confused.
"Grandpa is going to be pretty busy tonight…" said Gwen, trying to get her idiotic cousin to understand.
"…..ohhhhhh…" Said Ben as he started to realize what was going on. "Yes!"
"But you gotta act normal in front of Grandpa. We can't have him expecting anything."
Just as Gwen finished speaking, Max walked in the door and gave Ben a weird look. Ben looked down and realized he was still Four-arms. Grandpa shook his head, dismissing what he saw because he had more important issues to deal with. "You two are going to be alone for a little while again. Since us plumbers know what's coming, we're going to try to prepare and be able to defeat this threat quicker this time. But you two might be alone here for a few days."
"Aww grandpa. I don't wanna be stuck her with him." Gwen fake-whined. She than elbowed Ben.
"But I wanna go Grandpa!" Ben fake-whined as well.
"No Ben! And that's final." said Grandpa Max with authority.
"Fine." Ben said and he walked away pretending to pout.
Grandpa than turned to Gwen. "Here's fifty bucks. I don't have time to get you guys a hotel again so you're going to be stuck in the Rust Bucket. Will that be ok? The money's for food and fun. Don't go crazy."
"Alright Grandpa." Gwen said with a good whiney voice. "I guess we'll try to survive each other."
"That's my girl." said Max as he ran from the RV and caught a taxi.
"Alright, he's gone!" shouted Gwen and Ben ran to her and picked her up and swung her around, rather easily as he was still Four-arms. "We're gunna have to wait for you to get back to human before we do anything. We don't even know if aliens are like us or even have anything down there."
"That's right." said Ben. "But we could find out."
Ben than looked down at the pants and shirt that he never really realized Four-arms wore. Ben sat down and slowly pushed his pants down, half expecting to find another arm or something really weird. What he did find was the same penis he normally had, except it was red. And there were two. One on top of the other.
"Wow. I think I like this." said Gwen with a wink. Than she grabbed one penis in each hand and licked each of their full lengths and felt them getting harder in her hands. They kept growing harder and longer until they reached their full length, each being about and inch longer and wider than Ben's normal dick. "Oh I really like this." said Gwen as she pushed one into her mouth and jacked the other one off.
Ben as Four-arms starting panting feeling double the satisfaction as normal. But feeling double made him a lot more sensitive and he exploded cum into Gwen's mouth and all over her face. Ben blushed, feeling embarrassed that he had finished so quick.
Gwen looked up and smiled at him. She than wiped off her face and said "It's ok. You were just getting warmed up. Now's for the real fun." after she said that she pulled of her blue shirt, revealing her red training bra. Ben could feel himself getting hard again. Than Gwen dropped her pants, showing off her matching, cute red panties. Ben was definitely getting harder now. Than Gwen slowly pulled of her red bra, one shoulder at a time, slowly revealing each of her underdeveloped breasts that had actually grown about a cup size since the hotel stay. She than slid her panties down and flung them at Ben who grabbed them and held them, feeling his dicks shoot straight up and down. Gwen's vagina was beautiful, so tight and young, and the small patch of red hair that she shaved into a heart looked awesome to Ben.
Gwen seductively walked over to Ben and walked around the chair he was sitting in to tease him a little. She than climbed onto Ben's lap, with her back to him and began to push down with one dick in her pussy and the other in her ass. Than she started moving slowly up and down with lots of moans since she was unused to the size and it hurt a little bit. Than Ben wrapped his arms around her and squeezed her young gorgeous tits as he began pushing her up and down forcing her to moan loudly. Even with his huge muscles and structure Ben was being extremely gentle, being afraid to hurt his cousin. Than Ben start pushing Gwen up and down on his cock faster, being a little rougher with each thrust, forcing his dicks deeper into Gwen and making her moan louder till the point of screaming with each thrust. Than Ben began pushing up with his waist with each thrust of Gwen down, being a lot rougher and forcing his dicks deeper into her till the point that they were nearly fully inside her. Than he got up off the chair while holding her up and staying in her ass and pussy and walked to a bed where he put her down and got inside her again and started madly slamming in and out of her making her scream from pleasure from his roughness. She loved when he was really rough and she loved how deep he was going. He than start going faster and faster until he shouted "I'm gunna cum!" and exploded into her, filling both her ass and pussy with cum. Which made her scream and orgasm and squirt cum of her own all over his dicks. Than finally, from exhaustion, Ben turned back into His normal human self.
"That was great!" said Gwen as she flung her arms around Ben and held him to her naked body and kissed him slowly for a long time. As time passed the kiss grew deeper and more passionate as they each pushed tongues into each others mouths and rubbed them together. Finally they had to stop to breathe and smile. "You know, I wonder what other aliens in that watch have. Maybe we could have even more fun."
"Yeah definitely." agreed Ben. "Let's see what else I got to use. Heatblast?"
"No. He'd probably burn me."
"Alright. Not Wildmut or Ghostfreak. I don't have enough control of them. Diamondhead?"
\ "No. He'd probably cut me all up."
"Darn. Stinkfly and Upgrade wouldn't work either. I got it. XLR8!"
"Yeah Ben. That should work." Gwen than kissed Ben. "Turn into him."
"Alright." said Ben as he opened the omnitrix and shifted it to XLR8 and than slammed it down. For once it actually worked right and he turned into him. "Yes!" exclaimed Ben as the face shield lifted and he pulled off the entire helmet. Than he looked down at the one piece suit he was wearing. Gwen walked around his back and found the suit's zipper and she pulled it down, showing off Ben's naked blue body. But there was one problem. XLR8 had a vagina. It was a girl. Ben than looked down at the body and realized the suit had squeezed the body to the point of it being extremely thin and fast. But now that it was off, XLR8's body had turned into a full sized human woman body. Complete with a full D-sized breasts and great hips.
"Oh no." said Ben extremely saddened. "I guess we can't have sex."
"Maybe we can." said Gwen as she pulled he spell book and flipped to a page near the end. She than spoke a Greek spell. Her clit popped out than kept growing until it was a seven inch long cock. Ben could feel himself getting hornier and hotter, but now his nipples got hard instead of his dick. Gwen's nipples grew hard as well as her dick.
"I found this spell. And I guess I found the perfect reason to use it. This will probably hurt at first, but than you'll love it." after she said that she pushed the full woman sized blue Ben down on her bed and got on top of him. She than pushed the tip of her dick in his vagina and listened to him squeal from pain and pleasure. She than thrusted the whole length into Ben's pussy and he screamed and squeezed Gwen's breasts and she squeezed his and she started slamming into Ben. Moving her cock deep and fast as she fucked him hard and they both screamed and moaned from loving it so much.
"Gwen you're fucking amazing." Ben yelled as he orgasmed and squirted all over Gwen's dick and Gwen exploded and came all inside Ben's XLR8 pussy.
Once again, from satisfaction Ben turned back into his human self. Gwen once again smiled and kissed him. "Sex is gunna be a lot more interesting now that we know about your other special powers."
"Yea." said Ben, being almost too stunned to speak from how great that had just been. "Ok Gwen. I have one more idea for an alien for us to fuck with before bed. Go get in the shower and wait."
Gwen stood up and bent down right in front of Ben to pick up a towel from the floor and gave Ben a great view of her great, tight, young pussy. Than she walked into the bathroom, leaving the door open of course, and turned on the water and got in and started playing with herself in anticipation. She than saw a flash of green light from her room, signaling that Ben had changed again and she stopped playing with herself and waited for him. After a few minutes of standing and waiting Gwen got confused. Than she felt her pussy, like she was being fingered perfectly and she began screaming and moaning.
Ben had turned into Grey Matter and climbed up Gwen's leg and now was rubbing her pussy from inside.
Gwen started screaming and moaning louder. Ben felt so amazing inside her. She felt like she could orgasm any minute, but she tried holding it in as long as she could, wanting to orgasm as big as possible. Finally it was too much and Gwen screamed and her pussy squirted like never before, forcing Ben out along with a mass of cum. Ben than turned back to his normal self, still covered in Gwen's cum.
Gwen licked his face playfully, than kissed him as he pushed his hard dick into her soaked pussy and he began slowly and passionately fucking her as they made out. Slowly they made there way out of the shower and onto Gwen's bed even though they were still soaking wet. They kept fucking, with each thrust Ben going deeper into Gwen with his dick and Gwen moaned softly into Ben's mouth between kisses.
"Ben, baby, I'm gunna orgasm." said Gwen softly as her pleasure built and built.
"I know babe. Me too. Cum with me." After Ben said this, they both came. Ben filling Gwen with his hot cum and Gwen coating Ben's dick. They than both made out until they feel asleep in each others arms with dick still in pussy.
