Penny sat a top a stool in her lab looking at the latest results of her work on energy deflection. She'd altered the nano tubes as much as she could and yet they showed no discernible increase in their ability to deflect any more energy than they did. She'd used silicone, carbon and exotic combinations and still nothing.
Most people would have given in to frustration and possibly rage but Penny wasn't wired that way. No to her all this meant was that she had discovered one more mystery of the subatomic world of physics. Mysteries were to be solved and the pursuit of solution was her drug and she was addicted.

[B][I]Penny......Penny........Miss Penny, it is time to close this project and attend armor training[/I][/B] says a soft feminine voice from the air around her.

[B][I]Oh...is it that time already Matilda?[/I][/B] asks Penny as she moves her hands through the holodynamic control board and puts her research to bed

[B][I]Yes Penny it is that time once more[/I][/B] answers Matilda with a soft chuckle

[B][I]Okay then please prep Maiden to the required specs of today's lesson plan.....oh and did you replace the catheter with the one designed yet? The standard one made me itch after insertion[/I][/B] asks Penny as she hangs her lab coat on it's hook

[B][I]Of course Miss Penny, we can't have you itching after class....the urge to scratch is unlady like[/I][/B] adds Matilda as she confirms that she's altered Maiden to Penny's request

Matilda is like all the other aids at Stark and an extension of the Jarvis AI but Penny had customized her partitioned aid / companion. Her voice was sampled from Mary Poppins and Angela Jolie's Laura Croft and sense of humor. 
It wasn't that Penny didn't want a male voice so intimately connect with her but that she had no female friends 
When Penny exited her lab she's already changed into her academy uniform her hair pulled back into a flaming red ponytail as her tailored shirt molded to her curves with jaw dropping effect as did her slacks.
Penny knew why she had the affect she did on the opposite sex as well as a few of her own but the lack of self control was still a mystery. She herself found several of those around her arousing but she managed to control her physical urges and not stare.
She had come to a conclusion that trilled her surrogate parents and that was that she was most assuredly bisexual. She'd discovered this during unarmed combat training and she'd felt her body heat up in response to the contact more from desire for the person than friction. 
One day soon she was going to have to take a chance and enter the relationship game and try her luck her Uncle Fred had told her. He'd even suggested she take on multiple partners for comparison and fun. Most people would have been shocked by. Her and her surrogate Uncle's conversations but Penny adored them.
She didn't need to check in like the other students because she'd already committed the lesson plan to memory and knew that if there'd been another revision that she'd have been informed by Matilda. She instead went to the assembly point and using her pad began a check on everyone's suits and their position in the maintenance schedule.
That's when she received a text from Mr. Stark asking about her project and how her assessment of the Armor training was coming along. She sent him her finding thus far hoping his wonderful ability to see solutions could help and added that she was sure she'd receive a gold star for her attendance. 
Tony for his part asked when he'd authorized the wasteful use of gold and that he'd never got one when he was training in his armor.
When Penny signed off after trading a few light jokes with her employer she sighed. She was quite sure if he'd not been involved with Pepper that she'd have wanted to be among his conquests. His charm and skill as a lover was renowned and who better to begin to explore herself with than someone like him?
"Oh well she sighed as she resumed her eariler work with a bright smile
