September 1st 1994

Harry and Ron were chatting with Ginny when they saw Hermione come through the barrier onto 9 and ¾. She must have been running very late as the Weasley's had been early and still among the last to board the train.

She was wearing a nice skirt and blouse combo. As she got closer Harry saw she had a new wrist watch on.

"Hey Mione wow you missed a wild World Cup." Ron started when she came up and hugged the three of them in turn.

"Yeah I know. I was so worried when I found out. I'm glad you guys are ok."

"So what happened?" Harry asked.

"C'mon I'll show you on the train."

=====xxxxx=====

Ginny was sitting with them as she was worried about her friend Hermione. They got a bit concerned when she pulled all the curtains and locked the compartment door.

"Okay guys before I show you what happened to me I want you to understand this was an unplanned for accident. I made a rather serious mistake that could have happened to anyone."
"You made a mistake. Holy smokes! That can't be?" Ron exclaimed.

"Even the best make mistakes Ron."

"Yeah but you're better than the best."
"Thank you Ron anyhow may I continue?"
"Yeah sure."
She sighed then took her wrist watch off. Her body faded from view until a set of empty clothes remained.

"Blimey Hermione you're invisible!"

Her voice issued from the empty space in front of them "Very observant Ron. The trouble is that I am permanently invisible."

Harry frowned, "Permanently invisible?"

"Yes permanently. Only my body and anything that is actually physically attached to me like a pair of earrings or makeup are invisible. My clothes, my wand or anything else doesn't become invisible."

"So whats with the watch?"

"It has an anti-invisibility runic charm set on it. I had to do some pretty serious work on this thing to make it but when I wear this watch I am visible. If I take it off. This."

Harry reached out to about where her head would be and felt her bushy hair.

"Yes Harry I am still solid, just invisible." She said bending over to untie her shoes. The fact that from Harry's vantage point he could see right down her shirt to her skirt and saw a light blue bra and knickers caused him to take a sharp breath.

Hermione chuckled, "Yeah I know. Here hold my watch Harry."

Harry held it very carefully. Watching as her shoes, socks and then blouse all came off. Soon her carefully folded skirt joined the stack on the seat. A pair of light blue underthings floated in mid air.

Ron's breathing became hitched as the bra seemed to undo itself and join the other clothes on the seat followed soon by the knickers.

"Well I'm totally naked and none of you can see anything at all. And no Ron you can't touch me."

"Yeah oh okay."

Ginny chuckled, "Well this has got to be kinky."
"Yeah I plan on working a lot to grow stronger on my wandless magic. Which by the way did you know the trace doesn't work on wandless magic as most underage magicals are incapable of casting anything wandlessly."
"Yeah right and I guess you can?" Ron smirked.

"Well yes I can." She said Lumos and a warm yellow glow formed in the air.

"This is my right index finger. Pretty cool hunh?" She waved it around a few moments then canceled the spell.

"Okay show off."

Harry felt a weight settle on the seat beside him as a hand started caressing his right thigh.

"Well yeah. Sorry."
"So you're okay?" Ginny asked with a bit of relief.

"Well yeah. Aside from having to be naked if I really want to be fully invisible yeah I'm fine. Perfectly normal and healthy otherwise. And no I'm not going to go mad like Griffin did."
"Who?"
"The Invisible Man. H.G. Wells. Anyhow. I'm not going to go mad. Although I may play around and have some fun." Hermione's voice said as Harry felt the hand slid itself up to his groin. He bit his lip to avoid groaning as the unseen hand gripped his sensitive anatomy.
"Well yeah this is like having your own invisibility cloak." Ron said with a grin.

"Yeah except for the naked part. That's got to suck in the winter." Ginny said. Looking at Harry oddly.
"Yeah I am not looking forward to that." Hermione chuckled.

"Harry are you okay?" Ginny asked.

"Yeah peachy keen." Harry managed to croak out with his voice an octave higher as he was getting stroked through his jeans in front of Ron and Ginny by Hermione. Having her invisible was definitely changing things in their relationship.

"You don't sound okay man." Ron observed.

Harry felt his release building as he groaned out, "NO I'm fine." Stretching the vowels out.

He felt her lips caress his cheek before she whispered in his ear. "Come with me to the loo and I'll show you some more fun."

Harry got up and cleared his throat, "Sorry I got to go to the Loo." He said opening the door and feeling Hermione push past him.

After Harry left. "Blimey Hermione a bloke could have some serious fun with an invisible girlfriend."

When she didn't respond Ron started feeling around through open air, "Hermione? Hermione?" He sounded sadder with each repetition.

Ginny laughed, "I think her boyfriend and her are going off to have some more fun after she stroked him off."
"What no way. Harry and Hermione?" Ron asked with a dejected sigh.

"Yeah I watched his pants moving in a very curious manner as she stroked him off."

"Damn him. He gets all the luck."

Reaching the Loo Harry held the door open long enough to let Hermione get in. She had kept her hand on his belt so he didn't lose her.

Getting in the Train toilet she pushed him against the wall and taking his hands put them on her breasts. Their kissing was hot and heavy and she slid down his body to give him some oral arguments.

"Whoa you are really embracing your wild side." Harry managed to croak out after she was done.

"Well I always had a wild side but I never let it out because that would be improper at school. Now like this I can let it out and not be seen."

"Yeah you won't be seen. However I would be seen. And how are you going to carry things?"

"True I'll have to make sure to think about that."

Back in the compartment Ron and Ginny sat reading or staring out the window when Harry opened the door and came back in. His hair messed and his shirt button crooked.

"Have fun you guys?"
"Oh yeah." Hermione's voice as Harry slid back on the seat. Her clothes made a shuffle and she checked her watch.

Harry shifted as Hermione settled on his lap Her invisible form fitting perfectly against him.

"Is Hermione sitting in your lap?" Ginny asked with a grin.

"Yes I am." She said.

"So you two are boyfriend girlfriend now?" Ron grumped.

"Yeah."

"How come you're so open with this nudity thing and all."
"Well we go to France every other summer and have done so since I was a baby. Not to mention there is a naturalist beach in Cornwall that Mom and dad go to. And I might as well embrace it since this is the way I'm going to be for the rest of my life."

Ginny said, "Well I support you. So I'm good with it."

Ron shrugged, "I guess."
"I think you're just jealous because you're not getting any Ron. I know Lavender has mentioned she is interested in you."
Ron looked at Harry then frowning, "You know not being able to see your face makes it kinda hard to know if you're trying to con me or not Hermione.

"Sorry. I'm being serious Ron. No joke."
"Yeah okay. Well when we get to the castle maybe I'll check her out."

"Okay you do that."

Harry and Hermione began kissing and making out a bit before Ron and Ginny started laughing.

"Whats so funny?" Harry asked looking through Hermione at Ron.

"Sorry I know you guys are kissing and stuff but since all we can see is you Harry it looks like a very weird pantomime."
"Seriously Hermione could you come back to visibility. It would look a lot better."

"Yeah okay." She said as Harry reached up and obviously groped her breasts one last time before she began to get dressed. When she was fully dressed she put her watch back on and faded back into visibility.

Ron and Ginny had promised to keep her secret and they held to it. Ron had asked Lavender out and she agreed. It took a bit for the two of them to work out a balance in their relationship, with several false starts, breakups, returns, and cold spots but they managed to do so. Eventually becoming a solidly supportive married couple after the war with multiple children.

Hermione worked very hard to master wandless magic and helped teach it to Harry. With her natural invisibility she became an excellent spy, working with Harry under the invisibility cloak they patrolled the castle and encountered a young blonde girl named Luna Lovegood. They used their lack of visibility to help teach those who bullied her to be nicer people. Luna could always somehow sense Hermione even when she was invisible.

Hermione also used her invisibility to sneak into the boy's dorm to sleep with Harry quite frequently. Although she was almost caught one morning in the shower when the steam outlined her. Fortunately it was just Ron who walked in on her and Harry so he pretended to ignore her.

During the war she used her natural invisibility to spy and scout and steal through dangerous places. Although a Homenium Revelio would still show her, and she showed up on the Marauder's map.

Ginny and Neville had helped each other over the years and fallen in love. After the war they married and became professors at Hogwarts. Although Ginny spent some years on the pro Quidditch tour.

Luna never married but she remained very close personal friends with Harry and Hermione. And if some of her children had bright emerald green eyes no one ever asked about it. Harry and his wife Hermione rose through the ranks at the DMLE. Hermione's special ability one of the deepest secrets Harry protected. Their children were visible which was a relief to Hermione as she was concerned if the invisibility would breed true. Harry had worried a little bit but said they would have figured something out if they had. Their lives were long and happy.
