Hermione can hear Cho's screams of passion subsiding.  They get more quiet as Cho recovers and as Hermione walks down the hall away from that not-quite-closed door.  Professor Snape comes storming through a side hall right toward her.  Doesn't that guy ever sleep?  He's marching right along as if he's out to investigate something.  Guess which way he turns when he gets to Hermione - toward Harry and Cho.  Hermione is confident that she's invisible in her catsuit, so she just steps out of Professor Snape's way.
She needs a diversion, though, or the professor will catch her friends in their very friendly act.  She quickly thinks of a charm she could use to enchant any of several things around the hall.  She can't.  No wand.  She's caught out without her wand and she's as mortified as if she was caught naked.  Oh, wait.  She's that, too.
"The pocket!" she thinks.  "This is suit built for witches of our sort, after all.  That pocket is for a wand."
She'll be able to carry it in a place where the tight suit doesn't need to bend.  That's no help now, though.  She sees a suit of armor standing at the side of the side hall.  Like all the others, the hollow knight inside is fast asleep in the shining armor.  She dashes over to it and unhooks the round shield from it's metal glove.  She sails the shield down that hall like a Frisbee.
"CLANG!" goes the shield as it hits the stone wall.  Professor Snape stops in his tracks. "Clatter Clank!" the shield bounces off the stone floor.  Professor Snape turns around and comes back to investigate this noise.  "Clang Clackity Clunk rattle" the shield hits another wall, falls to the floor and slides farther.
"Damnable poltergeists," Professor Snape mumbles as he marches past Hermione.
The young witch smiles, proud at being able to put one over on Professor Snape.  She prances along the hall to a dark corner.  She waits in the shadow until Harry and Cho come out of the classroom.  They're dressed and skulking along under Harry's cloak.  Hermione hopes her gray suit hides her in the shadow.  She scrambles away before they get close.
Hermione runs to the Gryffindor tower.  She expects Harry to see Cho to the Ravenclaw wing and perhaps they'll enjoy a lingering good night kiss.  Hermione will have to be inside Gryffindor house to avoid being seen, then she can take her time getting through the commons.
The fat lady in the picture is asleep, as they all should be at this hour.  Hermione wakens her by saying the password, "Color of Night."
"Come right ahead, Hermione," says the groggy lady as she unlatches her frame.
Hermione pulls the door open and starts to step through.  Her glance happens onto a landing on the other side of the ever-changing staircase.  Professor McGonagall is standing there under her cloak.  She's covered from the tip of her pointed hat to the tips of her pointed shoes.  She's invisible to everyone except Hermione.  She'll also be visible to Harry and Cho soon enough.  She's dressed all in black as usual and there are shadows around.  Maybe she just wanted to be seen this time.
They make eye contact.  Professor McGonagall smiles with something that looks like pride.  Hermione's smile is much more sheepish.  She realizes just how much detail her skin-tight suit, or rather suit-colored skin, shows.  She goes through the door and closes the picture frame behind her.  That brings the fat lady fully awake.
"That was Hermione, wasn't it?" the fat lady asks nobody in particular.  "Right. Of course it was."
Hermione enters her room quietly and leaves the door ajar a little to let in some light.  She stands in the shadow, opens her dresser and gets her nightshirt.
"Granger?  Is that you?" comes from Ginny Weasley in her bed.
Ginny wouldn't see Hermione in that suit anyway, but she'll be less suspicions if the sound comes from a shadow.  Ginny hasn't made too much fuss about Hermione being out late, at least since that one time last year with Viktor.
"Yes, Weasley, just off to the loo.  Go back to sleep,"  Hermione assures.
Hermione goes to that little-used washroom on another floor.  You remember the one that goes unused because it's haunted by the ghost of a former student - Moaning Myrtle?  She lives in one of the toilets there, you see.  She does, too - Myrtle sees, that is.  She sees Hermione in that suit.
Hermione stands in front of the mirror and tugs at the flap below her hood.  It doesn't whip right off this time.  It takes a constant, hard pull to get the fabric loose from her skin.  The fabric and her skin both stretch.  Hermione gets worried that it will hurt or maybe tear the fabric.  Neither of those happen.  She just has to keep pulling steadily.  Her face and head are slowly revealed in the mirror reflection.
"Kinda tight, isn't it?" comes from one of the toilets.  "At least you can get it to stay on you."
That would be Myrtle.  Harry, Hermione, Ron and several others are acquainted with Myrtle.  Only a few tolerate her, and only when they have to.  She's such a downer with her complaining, whining and, well, moaning.  Hermione keeps tugging and peeling the fabric off her body.
"Good evening, Myrtle," she greets the ghost with half a turn toward her.  "Can you see this suit I'm wearing?"
"Ghost, remember?  Half here and half in another dimension.  We can see the invisible,"  she answers.  "I only see the suit where you peeled it off.  Otherwise, it's your skin ... all skin ... and just you."
Hermione accepts that, but wonders at the way Myrtle expressed herself.  She keeps peeling the suit down her arms and chest.
"Oh, my.  Have you grown in a sudden spurt or has someone been playing with your tits?  It must be nice to have ones that can be touched."  Myrtle points out something.
The ghost has another reputation.  Beside being such a sad drag, she uses her place in the plumbing to look over the student's bodies.  Harry told a few very close friends about the time in the prefects' bath last year.  He wondered why the sight of his naked body didn't impress the ghost girl very much.  Hermione rolls her eyes about Myrtle having a good enough impression of her body to make a comparison.  It is a valid comparison, though.
"They are quite engorged, Myrtle, but it's self inflicted.  I have trouble keeping my hands off myself when this suit gets so smooth on me," Hermione admits.
She peels off more of the suit.  She's comforted to see her body with all the familiar colors around her face, nipples, pubic hair, vulva and a few assorted moles.  She has the suit peeled down to her legs.  She sits on a toilet so she can reach lower.  No, that's not Myrtle's toilet.
"It's a shame you have to take care of yourself.  At least you can," Myrtle says.  "Hey, did that hole come in the suit?"
Hermione follows the ghostly pointing finger to her suit.  It seems there's a little finger-size hole in the exact center of the crotch.  A hem is now neatly stitched around the hole.
Hermione blushes bright red when she admits, "No, that's self-inflicted, too."
Myrtle gets a bright, mischievous smile on her face.  That's the first of those Hermione's seen on her.
"Did you finish well enough?" the ghost asks pointedly.
"Not really.  There were distractions, but why would you care?"  Hermione replies.
"Mmm, I wish ..." Myrtle muses, then disappears into her toilet.
Hermione tugs her suit off down past her knees.  That thing goes on easily and quickly enough.  It should be much easier to remove, she thinks.  Of course, then it would have to stay out of her skin and wouldn't be as much fun by far.
Myrtle suddenly pops up in Hermione's toilet, right between the witch's legs.  Hermione is leaning forward, reaching to her knees.  The ghost girl sticks out her tongue at Hermione's face and turns toward her body.  Myrtle puts her tongue out as far as it will go and licks upward through Hermione's vulva.  Hermione just watches.  She feels nothing from the formless ghost, and doesn't really like the idea.
"That isn't working, Myrtle.  Sorry," Hermione informs her.
The suit is bunched at Hermione's knees and the stretch is holding her legs together.  It's hard for her to stand let alone walk away.  Hermione reaches for the handle and pulls.  Myrtle flushes away in the swirl.
Hermione finally gets the suit off and her nightshirt on.  She's seen and greeted by another girl on her way back to her room.  It's comforting to know that the invisibility wasn't permanent.  That's just one of the thoughts that troubles her sleep.  She questions just what she was to learn by skulking.  She would be very surprised if the sexy lesson she observed is what her professors intended.  That gets her to the guilty feeling about her voyeurism - especially for watching the closest of her friends becoming intimate for the first time.
She decides to start studies of two things in the library tomorrow.  Reading and studying are where she's comfortable.  That thought is enough less troubling that she gets to sleep at last.
She's up bright and early.  She's dressed and leaving when Ginny first stirs.
On her way out the door, she just manages a chirpy encouragement, "Up Weasley!"
She finds Cho walking ahead of her to the library.  The shy Scot is perky, peppy and very excited.  She must have liked something about last night.  She is walking funny, though, as if something's irritated.  Hermione catches her up and tries to give as bright a greeting as she gets.
The one librarian is always on duty.  She never seems to sleep.  Is she some other sort of ghost?
"Right.  Chang and Granger.  You can go on back," the librarian motions toward the shelves.
"What?  No supervision?" Hermione asks and Cho looks shocked.
"You're going to the section for that book, aren't you?" she asks pointing at the book Cho had last night.  "Students on the total access list only need supervision in the heavy magic sections.  You know, to keep you from reading about conjuring monsters with a wand in your hand, or some such."
Cho shrugs, smiles and takes her book back to that section of the shelves.
As soon as Cho gets away, Hermione says, "I want something on invisibility, actually."
"Oh.  This way, then," the librarian obliges.
The librarian gets up and leads Hermione to the correct shelf.  She's also still sitting at the desk.  Hermione takes one of the books she's shown.  It looks about right for what she needs to know now.  She thanks the librarian and follows after Cho.
The subject of Cho's book is the other thing Hermione wants to study - sex.  After last night, she thinks she's way behind her classmates.  Do you think it's that or that Cho's ahead?  Cho raises an eyebrow when Hermione starts looking over the selections on that shelf.
"Th ... This one ... It helped me the most ... a ... and I read several," Cho says as she hands Hermione the book from last night.
Through all that, the shy girl was looking down, talking softly and blushing brightly with a sly, sheepish grin.  Hermione notices a different volume on the same subject in her hand.  Perhaps something more advanced?  Who would need to be more advanced than those two were last night?
The girls meet up with others outside the dining hall before breakfast.  Harry walks up looking a little tired.  He gives Hermione a nod, but not much of a smile.  He gives Cho a quick but close and warm kiss.  Ron and some of the other boys give him "Ooh" and catcalls.  He and Cho both blush brightly and pull each other more tightly with the arms they have around each other.  That'll teach them.  They can't walk very far with their arms around each other.  Cho has to sit at the Ravenclaw table.
"As you like to read so much, Hermione, there are some books I could recommend.  The subject is invisibility,"  Harry starts in a tone of light banter.  "One needs to know of things that are merely naughty and of things that are truly dark and bad.  I do think you would know and draw the line at merely naughty."
The others think its just more teasing about how much Hermione reads and studies.  She remembers how Harry acted almost like he knew she was there last night.  He didn't get it right about where she would draw the line, though.  Hermione replies by holding up the book she just got from the library.  Harry doesn't understand her blush.
"That will do," Harry approves.
Hermione turns to Ron for some more light talk over the waffles, "So, Ron, did you have a nice dream last night?"
"Rather.  I've been having good ones almost every night lately," Ron says, then gasps.
He looks around at Harry, Neville and Ginny.  They would be able to connect that statement.  Fortunately, their attention is elsewhere.  Hermione gives him a happy, knowing smile that he thinks is just friendly.
"Glad to hear," she says and goes on to other stuff.
Their first class is with Professor McGonagall.  Gryffindor is together with Ravenclaw.  The students come scurrying in.  Cho is walking in company with Hermione, Ron and Harry.  She's trying to keep up with their fast walk and looks quite uncomfortable.
The professor calls Hermione to the front before class starts.  She looks Hermione up and down as the youngster approaches.
"Well, did you learn much while skulking about?"  Professor McGonagall asks.
"More than I expected.  It was exciting to observe what I saw, but more uncomfortable to think about it afterward.  Did that go beyond naughty skulking?  Is that the sort of thing I'm supposed to learn?" Hermione wonders.
"Well, if you mean observing those two who were sneaking in after you, yes.  That's exactly what we would have you learn about.  It's naughty, yes, and it can be a little dark but more a part of growing up.  You can make good use of both the books in that pile, as is your way.  Take care, though, to learn from experience," Professor McGonagall instructs.  "Did you experience that suit and what it does when worn with nothing else?"
Hermione has her back to the class.  Only Professor McGonagall sees her shrug her shoulders forward, squeeze her breasts between her arms, reach both hands down to her skirt and press against her mound.
"That ... that was ... extraordinary," Hermione stammers remembering what compelled her to keep her hands on herself.
The professor nods to acknowledge that and dismiss Hermione.  She gets on with the class.  It's as delightfully filled with magic as everyone expects.  Hermione misses a lot of it because she's thinking about what the professor said to her.  They really do expect her to see and learn about graphic and intimate goings on.  It strikes her that Professor McGonagall said to learn by experience - experience, not observation.  She's preoccupied with that all through the class.
At the end of class, Professor McGonagall calls Cho to her desk.  Hermione and Harry are having some discussion nearby.  They pretend to continue while eavesdropping.
"May I suggest, Cho, that it is less irritating after that special night if one walks more slowly," the older witch says quietly.
Cho puts her hand over her mouth and flees before she's dismissed.  She dashes up between Harry and Hermione blushing and sweeping the room with wide eyes.
"H ... How many know ... about us?" she asks with a tone of panic.
Harry puts his arm around her and gives her a squeeze.  He hopes that will comfort her as much as it thrills him.
"Know?" Hermione tries to seem innocent.
"S ... Surely you guessed ... in the library," Cho answers.  "W ... With you, I'm not ... ashamed."
Hermione spends a lot of time thinking of skulking about, that catsuit and "experience."  She goes through the rest of the school day, supper, studies, extra reading and a little time in the commons with that distraction.
She has the usual banter with the usual tension between herself and Ron Weasley.  It's the sort of picking at each other that just asks for attention.  Hermione has that figured out tonight and gives Ron plenty of attention.  She's saying goodnight to her friends at bed time when an idea strikes her.
"Pleasant dreams, Ron," she says with another knowing smile that Ron doesn't get.
Her thoughts follow that into a plan.  She walks back to her room slowly while she thinks it through.  Ginny is in the washroom when she gets there.  Hermione changes into her nightshirt and carries her catsuit and wand to Myrtle's washroom.  She strips off the nightshirt and hides it behind a box of tissues.  She sits to pull the suit up over her legs.
Myrtle pops out of the next toilet.  There's no greeting, just a leering expression on her ghostly face.  Hermione reaches for the handle of that toilet.  Mytles expression changes to fear and she ducks down into the water.  The ghost pops up again several toilets away from Hermione's reach.  She just keeps watching without trying anything, so Hermione leaves her alone.
As soon as the suit is up over her legs and hips, Hermione checks it out.  The leg seams are crooked and wavy again.  The pocket shows clearly, running along the straight outside edge of her thigh.  She quickly slips her wand into the pocket.  She watches as the seams disappear and the gray fabric starts to blend with her skin.  The fabric of the pocket tightens around the wand, then relaxes.  It stays in the form of a pocket.
She stands in front of the mirror.  She can see her body from the waist up.  There's no reflection of her hips or legs.  The wand doesn't show either.  She reaches into the pocket with two fingers, grabs the end of the wand and whips it out with more force than usual.  It comes easily.  The extra effort makes Hermione's little breasts flip and shake about on her chest.  Myrtle sees that and moans.  Hermione sees and feels it.  Her other hand goes to her breasts, she scowls at Myrtle and then rolls her eyes.  She doesn't have the suit all the way on and she's already fondling herself.
She easily slips her wand back into the pocket.  It kept the second layer of fabric out of her skin ready to hold the wand again.  Hermione pulls the suit up, slips her arms into it and puts the hood over her head.
"How do I look," she asks as she spins around in front of Myrtle.
"To die for," moans the ghost.
Hermione checks for herself.  She sees nothing in the mirror, so she has to check with her hands again.  All her hair is gone.  Her body is smooth.  After the suit blends with her, everything feels like the soft girly skin that always covers Hermione.  Her firm breasts yield to her lifting and squeezing of them.  Her nipples harden under her touch, then tingle when she tweaks them.  Her buttocks are round and soft with no fabric bridging the separation between them.  She can feel every detail.
She carefully checks her vagina before she gets too carried away.  The hole in the suit has put itself in exactly the right place.  Hermione can get her finger where she will want it to go in just a minute.
She starts on her vulva in earnest.  The fingers of one hand stroke slowly around her legs and mound.  Her other hand lingers on her breasts for a while.  She gets to her labia and her stroking gets faster - as fast as her gasping breath.  One hand gets to her inner labia and vagina.  She has a finger working inside herself while the others work around the opening.  Her second hand arrives at her mound and those fingers find her clitoris.  The intense tingling of two-handed stimulation works quickly on Hermione.  She's soon mixing the gasps with squeals and her whole body is shaking around on wobbly legs.  She reaches climax, pulls her fingers tight against herself and something near a scream forces its way out of her tight throat.
When she recovers her senses, Hermione finds herself sitting on the washroom floor.  Her legs have given out.  She becomes more aware and her breathing eases.  Her heart is still pounding, though.  Soon she can feel the hard stone floor under her as if she were completely naked on it.  That's because she is sitting on it with bare skin.
"Finished well enough that time.  I don't have to worry about you, do I" Myrtle observes.
Hermione just sighs.  She stays there only as long as it takes her legs to stabilize.
Her plan calls for skulking into the boys' wing of Gryffindor house.  She gets through commons easily enough.  The prefects are busy with other things, so they don't notice either door open with nobody there.
Hermione passes boys in various states of dress, mostly in night clothes.  Some are in boxer shorts or briefs.  She thinks she prefers briefs because she gets a better view.  Some of the boys are as well built as Harry.  Some are bony, some are softer and some even flabby.  She passes some rooms with doors variously open, closed or in between.  The open ones give her more views of the forbidden boys' rooms.  They're actually a lot like those in the girls wing.  They all are the same size and have the same furniture.  They're populated by individuals, though - all different.  The boys rooms are decorated differently as a whole - more of the sports and less of the frilly.
The boys are not all on their best behavior.  Some are bickering, some teasing in jest or to torment.  Yep, that part is just like the girls' wing, too.
She skulks into Ron's room and quietly closes the door.  Ron is asleep in one bed and Harry is on the other.  Ron is lying under covers on his side with his head on the pillow.  Harry is mostly dressed, sitting up, back against his pillow, has a book open on his lap and has left a candle burning.  He's slumped back against the wall behind his headboard.  Now why would he be so tired?  Whatever will he do when he meets Cho tonight?
Ron is more of Hermione's concern this time.  She walks to his bed and looks down at him.  He seems to be sleeping soundly and peacefully.
"Pleasant dreams - of me," she whispers and kisses him on the cheek.
That seems to be enough to make him stir - perhaps enough to start a dream.  Ron breathes deeply and moans in his sleep.  His hands reach down in front of himself.  Hermione stands beside his bed, just watching.  Ron shifts and his covers slip off his shoulders.  He's wearing a tank top, so Hermione gets a little eyeful of his build.  He's not as sharply defined as Harry, but his muscles seem a bit larger.
Ron kicks his legs and rolls onto his back.  The covers are kicked completely off him.  Hermione gets another eyeful.  The shorts of his nightwear have a loose, open fly in the front.  Ron's erect penis has come out through that fly.  His head, the whole shaft and the testicles clinging nears its base are all out where she can see them clearly.
"Hermione," he whispers as he draws his arms to his chest as if hugging someone.
Hermione is thrilled that he whispers her name.  She imagines herself being embraced in that hug.  It's probably the same scene Ron is dreaming.  She finds her hands at work on herself again.  She has her vulva wet and excited.  Her labia are separated and really ready.
Ron moves his hands to his face, clutching as if someone's head was in front of him.
"Hermione," he whispers again as he kisses the face between his lips and his hands.
This is the best way her plan could have gone.  Hermione is sure now.  She'll make his dream come true, and enjoy it herself.  That erect penis looks far larger and more filling than any of her fingers.
She climbs onto Ron's bed slowly and gently straddles him.  She sits on his hips, pressing the shaft of his penis under her.  Ron's moans loudly and his hands go toward his crotch.  Those hands end up on Hermione's legs, belly and mound.  She gets extra tingles from being touched by someone other than herself.
She slides a little lower on Ron to release his penis.  She touches it with her finger tips, gently and even tentatively.  This is quite new to her.  She senses the hard shaft and the softer head at its tip.  Ron moans again and his penis twitches under her touch.  She takes it between two fingers and lifts it away from Ron.  It's stiff and gets hard to pull after angling up a few degrees.
She slides up on him so his penis is at her vulva.  It touches her labia and sends tingling sensations through her.  She thinks about what that is touching her and feels so ready.  She reaches down, lifts his penis again and presses against the head with her vulva.  Her labia part and let his head enter her.  She's not lined up properly.  There's too much pressure to the front.  She has to lean forward so his penis doesn't need such an angle away from his body.
That brings her breasts down onto Ron's chest.  His hands run up her sides and back.  He moans and whispers her name again.  The name and the filling pressure of his penis entering her are both thrilling.  She slides up and down on Ron, pressing against his penis more every time.  She can tell that her wetness is spreading around on him, wetting more of his shaft every time.  She can soon slide the first inches of it freely in and out of herself.  It rubs on that spot inside her vagina and spreads the tingling all over her.  She presses his penis in more deeply.  That takes some extra pressure.  As she rises to release that pressure, her clitoris drags along Ron's body.  That feels as good as his penis in her vagina.  She presses his penis into herself again and is sure to run her clitoris over Ron.
He's whispering her name again and again and running his hands where he can reach her back and sides.  She's leaning forward on her arms and brushing her breasts over him with every move.  The sensations in her vagina and on her clitoris drive her to drive him into her with all the extra pressure it might need.  She feels a sharp sensation as Ron's penis goes all the way into her.  That sensation is almost like pain.  When it's mixed with the tingles from her vagina and the pinch of her clit when it hits the base of his shaft, that near-pain sends Hermione into the most intense orgasm she's experienced.  She writhes, bucks her hips and rubs everything she can on Ron's body.  Her voice is in the act, too.  She doesn't choke back the screams this time.
When the intense orgasm releases her from its grip, she hears Ron grunting.  She opens her eyes to see his eyes open.  He's awake and having an orgasm of his own - inside her.  That thrills her even more.  She tenses all over again and another wave of passion sweeps over her.
Ron and Hermione both recover from their orgasms at about the same time.  Harry is now wide awake and staring at them - well, at Ron.  He can see Ron in his night clothes and it looks like his penis is still inside the shorts.  It's actually inside Hermione and invisible.
"What was that about?" Harry asks.  "No, wait.  Don't explain.  I know."
"She's here!  Right here on me!" Ron exclaims as he runs his hands over Hermoine.  "... and she's naked."
Harry knows of this sort of fantasy.  He's had enough of his own.
"Whatever, Ron," he says with a roll of his eyes.
"Really!  You said you thought she had something that made her invisible.  Well, it doesn't keep her from feeling good ... or being naked," Ron tries to reply.
Hermione pushes up on her extended arms.  Ron tentatively touches around her front to explore.  He finds the breasts he's seeking.  He presses on them and makes Hermione gasp.  The young witch was trying to keep quiet and tease the boys.  Harry hears the gasp.
"There is someone there!" Harry realizes.  "Who are you?  Show yourself!"
Hermione likes that idea - at least showing herself to Ron.  She'll have to show at least something to Harry.  She reaches for the flap under her hood and starts to pull.  She hasn't worn the suit that long, so the hood peels back quickly.  She leaves the hood on her back and shakes out her hair.  To Harry and Ron, her head appears over Ron's bed connected to nothing.
"It's really me," Hermione chirps at them.  "I must admit, Ron.  I heard you say you dream of me.  What better way to get my first experience?"
"You could have asked him," Harry accuses.  "You just jumped on and took advantage.  It's using the magic of invisibility for your own dark gain.  It's ... it's rape!"
Hermione blushes, not knowing how to defend herself.
Ron is a little quicker, "She made my dream come true.  I was dreaming of her.  She would know that I'd say yes if she did ask, but it would have spoiled the moment for her.  It was a good moment, wasn't it?"
Hermione can only nod.  She can feel less pressure from the penis inside her.  It's softening.  That's more new sensation.  So is the little pop it makes when it falls out of her vagina.  That's when it becomes visible to Harry and Ron.  Ron reaches quickly to tuck it into his shorts.  Hermione has to move for that.  She climbs off Ron and off the bed.
Harry is still disturbed by Hermione's behavior.  He takes a moment to think.  Hermione takes that moment to pull off more of her suit.  She quickly peels it from her shoulders and arms.  She finds both boys' eyes on her.  They see her bare arms and shoulders moving to push the suit down.  They gasp when that reveals her bare breasts, then her belly and hips.  The boys can see her pubic hair, her swollen vulva and a few inches of her legs.
"Hermione!" Harry protests.
"Hermione?" Ron wonders.
"This suit can be worn with nothing else.  It blends with my skin, so I am virtually naked when I'm wearing it.  Completely naked is the only way I can be when I take it off," Hermione explains.
"Not only do you take advantage of Ron, now you're showing us everything!" Harry protests again.
Ron defends her again, "She did as I would have wished.  There was no harm.  Far from it.  There shall be no complaint.  Now, I want nothing more than to see her."
"And do it again?" suggests Hermione.
"Whatever!  I ... I have to ... see Cho," Harry gives up for the moment.
Harry puts on his shoes, picks up his invisibility cloak and that parchment, and leaves the room.
Hermione sits on Ron's bed beside him.  She takes his hand and holds it to her still-invisible leg.
"It really was my skin you were feeling.  Pull here," she lets him peel the suit down a little more.
She pulls her wand from the pocket and finishes removing the suit.  Suit and wand wind up on the floor.  Hermione winds up on Ron.  He pulled her there as soon as the suit was free of her foot. 
"Really, Hermione, was that your first time?  Did you enjoy it enough?  I have no idea how long we were going," Ron asks
"Yes, it was my first time.  I'm so thrilled it was with you.  And, oh yes, I enjoyed it completely," she tells him.  "There's often a time in a girl's first experience when it hurts.  Rarely that hurt is orgasmic.  That's what happened to me.  It was right at the first penetration.  It didn't go long at all, but it didn't need to."
She starts the kiss and he returns it.  He starts the groping around her body.  She returns that with her hands all over his chest and shoulders.
His muscles are surely large and strong.  They're smooth and covered with soft skin.  Ron isn't interested in Hermione's muscles.  He goes for her breasts again.  Her nipples don't disappoint him.  They give a stiff reaction.  Hermione gives a gasping reaction when he rubs and presses on those nipples.
Hermione gets off him.  He looks alarmed until she reveals why.  She reaches for his shirt and pulls it up.  He sits up and reaches high.  She has no trouble stripping it off over his head.  He has no trouble seeing her body stretch up to reach - with her breasts right at his eye level.
Ron swallows hard when he realizes what comes next - his shorts.  He'll soon be as naked as Hermione.  He has to accept that when she reaches for his waistband and starts pulling.  He lays back and arches to release the shorts.  Hermione pulls them off, then investigates what they covered.
They're both look into his crotch.  They see what they expect - his soft penis lying across his testicles.  Hermione lifts it gently in the palm of her hand, looking at it closely.  This is more educational than any naughty picture or even watching someone from a distance.  They're both thrilled when Ron's penis rises and stiffens right there in her hand.  Hermione smiles at Ron.  The anticipation has her breathing heavily already.
This time he's awake and Hermione's not invisible.  Ron is enjoying this more than any dream.  He grabs her and pulls her on top of himself again.  She lies flat on him and feels that hard penis pressed tightly between their bodies.  He feels her firm legs, belly and soft breasts against him.  His penis twitches as he squeezes Hermione tightly and starts kissing her.
Ron's tongue licks across Hermione's lips.  She opens her mouth and meets his tongue with her own.  They lick at each other as if doing battle with swords.  Ron wins.  Hermione accepts his tongue in her mouth.  More new things.  This is even more exciting because its closely personal.  The kissing goes along with tongues shared back and forth.  Hermione feels more excited and starts wriggling on top of Ron.  She realizes what her body wants.  She rolls off Ron and lies on her back.
"I shall ask properly this time.  Ron Weasley, would you like to have intercourse with me?" she asks.
"Oh, right.  Be proper," Ron complains about the stiffness of Hermione's request.
The young witch does know the common language.  Ever been around a girls' dormitory?  Believe me, she knows.
"Well then, let's fuck," she shocks Ron.
"Let's quit asking and just do it," he suggests.
Hermione pulls him onto her, wraps her hands around his head and pulls his face into her kiss.  His hands work down her body past her soft and firm shoulders to her even softer breasts.  He knows there are other things for those hands to do.  He just can't get past those breasts.  They're so exciting to him.  Hermione can tell where his focus is.  She's glad he enjoys her breasts as much as she does.
She feels the tip of his penis tapping at her vulva.  That gets her focus.  She wraps her legs around Ron's hips and pulls him.  That presses his penis into her, but they're not lined up right.  Ron reaches down between them and checks how ready Hermione is.  He strokes her labia and sticks a finger into her vagina.  She presses her mound and vulva against his hand.  She likes this and wants more.  She's plenty wet and almost ready.  He uses a few strokes over her clitoris to complete that.  He can tell when she wants him.  She pulls him upward with her legs again.  He holds his penis at her entrance with his hands and lets her pull.  That slides him up her and slides his penis in.
Ron gets up on straight arms and starts with some thrusting action.  He goes slowly at first to spread her wetness and get everything sliding smoothly.  When he gets all the way in, he presses the base of his penis against Hermione.  That pinches her clitoris and brings a squeal from her mouth.  Gasps and squeals follow continuously after that.  Hermione matches Ron's thrusts with her own wriggles.  Ron matches that by thrusting harder.  He's soon pounding into her hard enough to move her whole body at each thrust.  He watches her breasts shake and jiggle.  Her hips buck up when he draws out of her, then fall back to the bed ready to be pounded again.
Hermione knows she's being taken as a man takes a woman.  This isn't the fooling around or experimenting of two adolescents.  Well, it is of a sort, but there's more to Ron's technique.  Ron's manly way with her and all the sensations he's causing drive her to orgasm quickly.  The bucking of her hips gets wilder and her squeals turn to muffled screams.  When the orgasm passes, she finds Ron's lips over hers.  She realizes it really wouldn't do wake all the boys around.
Ron keeps up the powerful thrusts and the impacts they have on Hermione's body.  She goes through all those feelings and actions again.  At the end of her second orgasm, she finds Ron stretched up, pressing as tightly as possible into her, every muscle tense and grunting.  He relaxes and lies on her.  He slides his penis in and out a few more times, then just lies there.  Hermione holds his head, strokes his shoulders and gives him little kisses.
"Mmmm," she sighs to herself.  She realizes that this is how contented cats must feel when they purr.
Ron pulls his penis out of her, rolls off and lies on his back.  He's breathing hard and smiling at her.  Hermione cuddles beside him.  She's on her side between his body and his arm.  She has her head on his shoulder.  It's the most wonderful pillow she's ever had.
"That was wonderful, Ron.  Thank you for making my first time such a pleasure," she whispers.
"It was great for me, too.  You really got it out of me," he answers.
They lie there cuddling for a while.  Hermione's heard that it's rare for boys to do that.  She thinks she's lucky with Ron in yet another way.  Ron must have sensed a little shivering, or maybe felt cold himself.  He pulls the covers over Hermione and over his own chest.
Most of her hair and face are covered and she's still when the door opens a while later.  Harry has returned.  He sees Ron drowsy, but awake, on the bed.
"Well, have you enjoyed doing our friend?" Harry starts on Ron.
"You know we both wanted that.  And how is it with you?  Isn't Cho a friend?  Of course you have feelings for her.  Accept that I have for feelings Hermione," Ron defends.
Hermione whips the covers off.  That reveals the completely naked body of Ron and the completely naked body of the very perky Hermione.
"And my feelings for Ron.  We're no different, you and I, in this way at least," she asserts.  "And we are still friends, right?"
Hermione ended that sitting up with a big smile on her face.  Something has made her feel peppy and cheerful.  She gives Ron a big kiss as she slides over him.  Harry gets a good view of all of Hermione's naked back.  Hermione sits at the edge of the bed and starts putting on her suit.  She slips her feet and legs in, then stands to pull it up over her hips.  She doesn't wait to pick up her wand and put it in the pocket.  She doesn't want a chance of the pocket disappearing.
Disappear is what she does.  She sees the crooked, wavy leg seams disappear and the threads of the fabric blend with the skin of her legs.  The boys see those legs vanish.  Hermione from the waist up seems to be floating in the air.  Both boys focus right in the middle of that apparition - on her breasts.
"Sorry to cover the eye candy," she says as she pulls the suit up.  "I take it that you saw Cho safely to Ravenclaw house."
"Yes, after we got past Professor Snape," Harry says brandishing his cloak.  "He must never sleep."
By then Hermione is all the way into her suit.  She bends down to the bed and surprises Ron with an invisible kiss on his lips.
"Good night, Ron.  Pleasant dreams," she says.
"Won't need them now," Ron answers.
She startles Harry even more with her hand on his shoulder when she says, "Good Night."
She strolls through the now-empty halls of the boys' wing.  She could go to her own bed, but she is under instructions to skulk about.  She feels too peppy and perky to sleep anyway.  She roams around the halls of the school for a while and finds herself quite alone with two exceptions.
One is the expected encounter with Professor Snape.  He comes strolling through the hall with torch in hand.  He seems to be walking aimlessly as if patrolling with no particular place to go.  Hermione winds up wishing he would have stumbled onto the other exception.
While she's returning to Gryffindor tower through the large entrance hall, the main doors fly open.  Several robed and hooded figures come in and close the door behind themselves.  They walk straight to the Slytherin dungeon.  On the way, many of them pull down their hoods.  Yep, they're the fifth and sixth year Slytherins.
"We're just playing at this.  It won't summon or conjur anything," comes from a hooded head in a girl's voice.
The boy beside her drops his hood to reveal the white hair of Draco Malfoy.
"Tomorrow.  That will be the third time.  Keep thinking it's play, if you want.  You'll find out," Malfoy answers her.
Hermione waits for them all to go by so she won't run into anyone.  She then makes her way to Myrtle's washroom.  She really feels the need for a shower.  I wonder why.  She starts the water, then gets under it still wearing her suit.  It probably needs a good rinsing, too.  Myrtle pops out of her toilet.  She sees the water sprinkling down over a void.  There's empty space under the shower where the invisible Hermione is standing.  Myrtle keeps watching until Hermione leaves.
Hermione peels off the suit still under the water.  It comes off as before - more quickly than last night, but more slowly than in Ron's room.  Hermione washes herself and then the suit.  She notices the hole in the crotch - it's now more than finger size and still neatly hemmed.
The suit wrings out nearly dry, so Hermione will be able to hang it in her wardrobe.  Her night shirt is still in place behind the tissues.  All in all, this has been a completely successful evening.
