A Twist Before

"Ok so... I just need to know what exactly you did to me before." Anna stopped Ben.
"Nothing." he said and giggle.
"Ah come one! You can tell me. I am not gonna be mad. Promise!" she beckoned him, but he just kept laughing for a while.
"Seriously. I did nothing!" he repeated "All I did was to boost my confidence with girls a little and figured that might help us to figure out something we can do later while watching the movie." Anna stared at him confused for a moment.
"Dude... I've been seriously horny ever since I left you alone with this god-like device, so don't tell me you did nothing!" she laughed, feeling slightly embarrassed.
"Well that's probably you having a fetish for god-like control then." Ben responded uncharacteristically direct, which made Anna question if he in fact actually just upped his confidence. She decided to change tactics.
"So what would you have changed then?" she questioned him.
"I don't know." Ben answered "That's what we need to discuss."
"Well I would have given you a bigger dick." Anna said with a smirk to lure the truth out with her own confession. "Well if that stupid program would let me..."

Ben stared at her sudden revelation dumbfounded for a moment, then realized: "You really do love changing people, do you?" Anna decided to stay silent and just smirk, hoping he would reveal his secrets now still. But instead he just continued: "So... like how big would you make me?"
"I... uh..." Anna was caught off guard "Dunno... what's in fashion these days?"
"Come on... you can't drop that line and then not tell me what you have in mind." now it was Ben teasing her.
"I... don't know just like... bigger I guess? What's wrong with a bigger dick, right?" she suddenly felt trapped in her own plan when Ben opened his profile, went for the dick size, and then stared at her, waiting.
"Just tell me, you are allowed to have some fun as well." he offered.
"I... I..." Anna stammered, desperately searching for an excuse. Especially she didn't want to offend him with a size that would make him feel too small. "I am really bad at deciding, you know." she finally decided for an escape. And for a moment Ben looked like he aborted his little stunt, but then with a smirk moved his focus to the free text command box.
"There is a thing I read in one story that might fit your fetish well." he pronounced that word in a way that made Anna shiver a little.

Anna can change the size, shape and state of my dick at will. No matter the change, I will always stay safe and healthy.

"You... seriously just did that?" Anna stared at him clearly excited, when a sudden tingle hit her. "Woooow..." she said slightly spaced out "I can now like... sense your dick and... do things..." Her eyes focused on his crotch blatantly, and suddenly Ben felt a little tingle followed by his cock expanding slightly.
"Figured that might help you for when you finally decide on something." he commented with a smirk, feeling strangely empowered by his recent confidence boost. He really just managed to go through this without dying like his former self would have. "How big did you just make me?"
"6 inches?" Anna said. Her nipples where rock hard and poking through her shirt. She clearly was turned on by this new power.
"Nice." Ben responded "So can we now watch the movie?"
"I guess?" Anna was breathing heavily. She really did have to get used to this new power she held over him. Probably a movie was indeed a good idea to keep her from giving into those urges that want to add a lot more than just a single inch to his cock.
"Well then..." he gestured towards the door. And when Anna walked through it he quickly added: "I hope my pants still fit me after the movie." causing Anna to giggle with a hint of power madness in her voice.
