Pleasurable Sensations




  It was a windy April day, and Luna Lovegood was wandering down the path to
  the lake, humming to herself softly. For some reason, Madame Malkin had cut
  her skirt quite fully that year, and Luna watched, pleased, as it belled out
  with the wind, rising up to mid-thigh. It looked pretty, like one of those
  old-fashioned hoop skirts. Unaware that a group of Ravenclaws was behind her,
  and a pack of Slytherins walking towards her, Luna continued walking,
  unconcerned.

  When a particularly sharp gust of wind caught her skirt and blew it up over
  her waist, Luna giggled slightly, and immediately smoothed it down. It was
  then that a jeering voice caught her attention.

  "Sweet Mother of Merlin!" Draco Malfoy was having trouble speaking through
  his laughter. "Loony Lovegood doesn't even have sense enough to wear
  knickers!"

  Luna stared at him, wide-eyed. "Why should I? It just makes more washing."
  From behind her, she could hear a chorus of giggles, and saw some of the
  Ravenclaws of her year trying to smother their laughter.

  "Nice rear end, Loony," one of them, braver than the rest, called.

  "Thank you," Luna said, automatically, trying to hide her rising concern. Of
  course, she wasn't terribly pleased that everyone had seen her private parts,
  but surely it was just one of those things that happened sometimes, wasn't
  it?

  "Will say this," Draco drawled, "You've got a nice little snatch. Maybe you
  should stop hanging around Gryffindors all the time."

  Luna flushed crimson. She'd never heard that particular word before, but his
  meaning had been unmistakeable, and the way Malfoy was looking at her made
  her feel...dirty. Deciding that feeding the giant squid could wait for
  another day, Luna hurried back up to the Ravenclaw dormitories.

  Curled in the window seat with her stuffed swan, Luna tried to analyze what
  had happened. Didn't they understand that it was just the wind? It wasn't as
  though she were some kind of exhibitionist. And it wasn't just the
  Slytherins, the other Ravenclaws had seemed to find it just as funny. Luna
  bit her lip, and resolutely dismissed the matter from her mind. It couldn't
  be helped.

  *****

  At the usual Saturday afternoon meeting between the headmaster and the heads
  of house, Professor Flitwick interrupted the usual bickering between Snape
  and McGonagall, and apologetically said, "I'm afraid there's an issue with a
  member of my house that needs to be dealt with. Miss Lovegood, actually."

  "Luna No Knickers Lovegood?" Snape smirked.

  "Yes, and I really believe this matter would have been far less problematic
  if the students of Slytherin house had not felt compelled to make up a song
  to that effect."

  "They're very musically inclined."

  Minerva shook her head impatiently. "Of course something needs to be done,
  but what? We can't be on the students constantly to make sure that they don't
  harass her."

  "That wasn't precisely what I was thinking," Flitwick said carefully. "I was
  hoping that one of the, er, female staff members would be good enough to - to
  ensure that this incident doesn't repeat itself."

  There was a moment of silence while this sunk in. "You want one of us to make
  Miss Lovegood wear knickers?" Professor Sprout said incredulously.

  Flitwick shifted uncomfortably. "Not to put too fine a point on it, yes."

  Professors McGonagall and Sprout stared at each other warily. McGonagall
  looked quickly at Flitwick. "Can't you just tell her? It needn't be a lengthy
  conversation."

  Flitwick shook his head vehemently. "Oh, no. What if she has questions? And
  someone will have to ensure that she gets the necessary garments. This is a
  matter for a woman to deal with."

  "Poppy," Professor Sprout said hopefully. "She could do it, she's used to
  this sort of thing..."

  Dumbledore shook his head. "I'm afraid Madame Pomfrey is far too busy at this
  time researching and stock-piling remedies to be able to deal with this
  matter." There was an infuriating twinkle in his eye.

  "I did that Slytherin girl," Sprout said suddenly. "The one who didn't
  understand about shaving." She shuddered slightly. "So it's your turn,
  Minerva."

  Minerva tried to think of a way to argue her way out of that, but it was
  true. It was her turn. "Oh, very well. I'll have a talk with her this
  evening."

  Snape leaned back, a broad smile on his face. "there are times when I bless
  the fates that decided to make me male."

  "Oh, Severus, that reminds me," Sprout said, "Ermie Macmillan's developed a
  habit of wanking quite audibly at nights. It's starting to make the other
  boys nervous. I trust you can see to the matter?"

  Snape's reply made even Dumbledore lift his eyebrows, and Minerva decided, on
  reflection, that she had perhaps gotten off rather easy.

  *****

  That night, as Luna finished dinner, she was startled by a firm hand on her
  shoulder. She turned, then relaxed. "Oh. Hello, Professor McGonagall."

  "Miss Lovegood. I'd like to speak to you for a moment, please." Minerva tried
  to keep her voice from sounding too sharp. She didn't want to make this any
  harder for the child than necessary.

  Luna nodded, and followed Professor McGonagall back to her office. When
  instructed, she sat down in a chair, crossing her ankles, and received a
  biscuit. Taking a dainty bite, Luna waited for Professor McGonagall to come
  to the point.

  "I'm sure you know what I want to discuss with you," Minerva said, cursing
  her own embarrassment over the matter.

  Luna shook her head, thinking hard. "Is it about class?"

  "No, Miss Lovegood. It's about - about the incident last week." Minerva
  gritted her teeth.

  "Oh. You mean when the wind blew my skirt up?"

  "That's correct. I understand that you - er - were not wearing any
  undergarments?"

  "I should think the song would have told you that," Luna said, her voice
  momentarily sharp.

  "Indeed," Minerva said, pleased at having penetrated Luna's dreaminess. Deep
  down, the girl was sensible. "I understand that you've been raised mostly by
  your father, and there are some things he may not have explained to you-"

  "Daddy doesn't like talking about girl things," Luna interjected.

  "Quite." Minerva contemplated reproving the girl for interrupting her, but
  decided that the conversation was problematic enough as it was. "The thing
  is, Miss Lovegood, I think you'll find that it would be better to begin
  wearing such undergarments, in case of future - untoward incidents."

  "It just makes more washing," Luna said doubtfully.

  Minerva bit her lip to contain the sharp comment that wanted to emerge. "Yes,
  but young ladies should always wear them. You want to be a lady, don't you?"

  "Oh, yes," Luna said, eyes wide. "Dad always said that what he loved most
  about Mother was that she was always a lady, even if she was taking off all
  of her clothes and running about in the front garden."

  Minerva choked slightly, but recovered herself. "So you see, you must begin
  to wear proper undergarments."

  Luna nodded thoughtfully, finishing off her biscuit. "I never knew it was so
  important. But I haven't got any, you see."

  "I'm sure your father..." Minerva trailed off as she imagined having that
  conversation with her own father, an eccentric recluse who lived by fishing
  and sheep-farming, and refused to allow English to be spoken in front of him.
  Obviously not a desirable option. "You can procure some in Hogsmeade."

  "I haven't any money," Luna said simply. "And there isn't another Hogsmeade
  weekend for quite a while."

  Pulling off her glasses, Minerva began massaging the bridge of her nose. "I
  suppose," she said grudgingly, "that I could take you into Hogsmeade
  tomorrow. We can have the bills charged to your father's vault. I'll write
  him a letter, explaining, discreetly, that you needed some new clothes."

  Luna nodded. "He won't mind. He's very generous. He's a good father, really."
  For the first time, her voice betrayed a hint of anxiety.

  Minerva smiled a bit, remembering how she had defended her father in much the
  same terms. "I understand. Very well, then. Be down in the entrance hall at
  nine o'clock sharp."

  "Yes, Professor," Luna said, standing up quickly and automatically smoothing
  down her skirt. She looked up at Minerva shyly. "Thank you."

  *****

  The next morning, Luna was downstairs ten minutes early. Despite the fact
  that Professor McGonagall was so far being very nice over the matter, Luna
  had been a little afraid of her ever since she'd arrived at Hogwarts. She
  could be very sharp in manner at times, and had reproved Luna and taken
  points for inattention and tardiness more than once. Luna began to tense up
  just thinking about it.

  When Minerva arrived in the entrance hall, she was pleased to find Luna there
  already. She noted a slight anxiety in the girl's face, but put it down to
  their rather unusual goal for the morning. "Very well, come along then."

  Luna obeyed quickly, and soon they were walking down the path towards
  Hogsmeade. Luna had to almost trot to keep up with Minerva's long stride.
  When Minerva addressed a short comment to her about the weather, Luna gasped
  slightly. "S-sorry," she said, breathlessly, as she received a sharp look for
  not responding.

  Minerva realized the problem, and slowed her stride. "You should have said
  something."

  "I'd've had to've caught my breath first," Luna said in a rush, settling into
  a more comfortable pace.

  A little smile threatened, but Minerva quashed it. It would be, she was
  beginning to realize, entirely too easy to become very fond of Luna Lovegood,
  and the last thing she needed was to grow attached to this airy, unfocused
  child. "Don't be impertinent," she said shortly, ignoring the fact that Luna
  hadn't really been impertinent.

  Luna bit her lip, her tension increasing with the reproof. "I'm sorry,
  Professor." So apparently Professor McGonagall still disapproved of her as
  much as ever. Luna was surprised at how bad that made her feel.

  They were quiet for the rest of the walk into Hogsmeade, and Luna felt quite
  unhappy until they actually reached the shop, and were in the delicates
  department. She'd never imagined that there were quite so many different
  types of knickers. "Which ones-?" she asked, awkwardly.

  Minerva pursed her lips. "It's really up to you, but I would think that plain
  cotton would be most suitable."

  Luna nodded quickly, and began picking out white cotton knickers. She was
  distracted, though, by the sight of a pile that were trimmed with eyelet.
  "Would these be all right?"

  "I suppose so." Minerva found that she was having to fight very hard not to
  imagine the delicate lace, nestled between Luna's thighs.

  Luna was distracted by the sight of a mannequin wearing a brassiere. "What's
  that?"

  "A brassiere. Don't you-" Minerva stopped at the obviously bewildered look on
  Luna's face. "Obviously not. Very well, we may as well do this properly. Pick
  out a few of those as well."

  Luna obediently picked out three brassieres that more or less matched her new
  knickers. Minerva made arrangements with the sales lady, then said, "Is there
  a changing room we could have use of for just a moment?" She was determined
  to get the entire situation resolved as quickly as possible.

  The young woman, smiling, directed them to a room, and Minerva nodded at it.
  "Very well. Go put them on." Minerva's tone was brusque.

  Luna, feeling obscurely ashamed, went into the dressing room, and Minerva sat
  in the small chair outside the room, feeling rather pleased with herself for
  having dealt neatly with the entire matter. Her complacency was interrupted
  by a small voice from within the dressing room.

  "Professor McGonagall? I think I did something wrong."

  "Well, perhaps you can correct it?" Minerva said, desperately.

  "I don't think so." Luna's voice was doubtful.

  Minerva murmured a few choice swear words she'd learned back in her
  Quidditch-playing days, and, gritting her teeth, opened the door to the
  dressing room. The sight that greeted her was even worse than she could have
  imagined. Luna's knickers were desperately twisted about her thighs, so
  tightly that Minerva wondered how on earth the girl had managed it, and her
  brassiere was strung from one shoulder to the opposite ribcage. Minerva
  didn't want to laugh, tried hard not to, but in the end, it was impossible.
  She covered her mouth with her hand, trying to smother the sounds of mirth.

  A look of ineffable hurt crossed Luna's face, and she turned away quickly.
  "Just tell me how to put it right," she whispered.

  Minerva quickly sobered. "Child, I didn't mean to laugh, but you must admit-
  " Luna didn't answer or turn around. "Come here," Minerva said, softening her
  voice.

  A small, instinctinve sound of denial escaped Luna's lips, as she continued
  to stare at the prettily patterned paper on the wall. "Never mind," she said
  after a moment. "I'll fix it myself."

  "Don't be foolish," Minerva snapped, but Luna didn't move. Impatient, Minerva
  strode over to her, unhooking the brassiere with a quick twist. "Come along,
  get them off and start again."

  Luna shuddered at McGonagall's fingertips brushing against her skin, and her
  breathing sped up slightly. "Can't," she breathed. "Too twisted."

  Minerva tugged the brassiere off, hearing a little whimper as the fabric
  caught on one of Luna's nipples. "Sorry," she said in a low voice, and laid
  the garment aside. She couldn't help, though, the rush of sympathetic
  pleasure that went through her at imagining the pressure on that small, soft
  nipple. She turned to the knickers, trying to slide her fingers under the
  fabric that was digging into Luna's hips.

  "They hurt," Luna said vaguely.

  "I'm quite sure they do, if you twist them to kingdom come," Minerva said
  tartly. "Just hold still." But of that, Luna seemed to be incapable,
  squirming as Minerva tugged and pushed patiently at the fabric. Slowly,
  laboriously, she pushed them down Luna's legs, but the girl's agitation
  didn't ease up. Instead, she shifted her legs, seemingly trying for maximum
  contact with Minerva's hands. Little shivers ran through her body, and her
  breathing was quick and excited.

  Minerva was discomfited, but could think of no reproof appropriate to the
  situation. Untangling the fabric, she held the knickers out, waiting while
  Luna stepped into them daintily. She tugged them firmly up the long, slim
  legs, trying to ignore Luna's increased shivering.

  As Minerva was just finishing pulling the knickers into place, her fingers
  brushed between Luna's thighs. The girl's body arched like a bow, and she let
  out a loud gasp, shuddered hard, and slumped against the wall.

  Minerva, shocked, was silent, and for a long moment, there was no sound
  except for Luna's soft panting as she recovered. Slowly, Luna opened her
  eyes. "What was that?"

  Minerva racked her brain for a way to explain to a fifteen-year-old girl that
  she'd just had her first orgasm. "Never mind. Here, hold your arms out."

  Luna shifted languorously, and allowed Minerva to put the brassiere on her.
  Her eyes were half-lidded, and she looked almost ready to go to sleep.
  Minerva, not wanting to prolong the experience any further, dressed the
  docile little girl, and propelled her firmly out of the shop.

  The fresh air seemed to revive Luna, and she said, as she trotted once again
  to keep up with Minerva's pace, "Professor, I'd really like to know what that
  was. Although, if you don't feel like talking about it, I suppose I can go to
  Professor Flitwick. He's very good about explaining things. I was having
  trouble with my Cheering Charms, but then he explained it very clearly and I
  did quite well on the exam."

  Minerva winced, and realized that she wasn't going to be able to get out of
  this easily. They were passing a tea shop, and she decided that it might be
  easier to handle the matter over a cup of tea. "Let's have a cup of tea, Miss
  Lovegood."

  Luna assented happily, and, once inside, agreeably accepted a cup of the same
  China black that Minerva ordered.

  Minerva stared down at her teacup, trying to come up with an adequate
  explanation. "As you get older, Miss Lovegood," she began cautiously. "You
  will find that your body is changing, and certain things may cause
  pleasurable sensations."

  "Like touching between my legs?"

  "Yes. These things are enjoyable, but private." Minerva struggled with
  herself. She had always advocated teaching children honestly about the
  pleasures of their own bodies, but had never expected to find herself in the
  position of having to do the teaching. "You may find, with some
  experimentation, that you can bring yourself to these pleasurable sensations.
  You want to be cautious, though, about who else you allow to touch you, until
  you are older. Boys, for example..." Minerva trailed off, trying to frame her
  next statement.

  Luna, however, nodded. "Dad told me a little bit about that. Not letting boys
  touch me and so forth."

  Minerva gave a sigh of relief. "Very good. Just remember, these feelings are
  natural, but very private. You mustn't talk about them to anyone."

  Luna nodded again, seriously. "I won't. But may I talk to you about it? If I
  have questions?"

  Minerva pressed her lips together tightly. "If you must."

  Luna finished her tea quietly, having sensed that Minerva didn't feel like
  talking just then, even though there were a good many more things that Luna
  wanted to know, chief among which was why she felt so oddly damp between her
  thighs. When they had both done, and were ready to return to Hogwarts, Luna
  inserted her hand into Minerva's a little hesitantly.

  Minerva was startled, and embarrassed, but could think of no way to remove
  her own hand without hurting Luna's feelings. And, in truth, the soft little
  hand in her thin one felt nice, childishly alluring.

  They were just crossing the long grounds of Hogwarts when Professor Flitwick
  approached them. "Ah, Professor McGonagall, Miss Lovegood. I trust you
  procured everything that you needed in Hogsmeade?"

  "Oh, yes," Luna said calmly. "Would you like to see?" She made to remove her
  hand from Minerva's to open the bag, but Minerva held it tightly.

  "Miss Lovegood, I believe it is time you were returned to the castle.
  Immediately." Minerva's voice was very sharp.

  Luna looked up at her, wondering what on earth she had done wrong. Minerva
  seemed to change moods so unaccountably. Sighing, Luna said goodbye to
  Flitwick, and allowed herself to be led up to the castle.

  *****

  It was only three days before Luna sought Minerva out again, and in
  retrospect, Minerva was only surprised that it had taken that long. Luna came
  to her office just before curfew, and stood in front of Minerva's desk,
  politely waiting to be invited to sit.

  "How can I help you, Miss Lovegood?" Minerva made her voice deliberately
  uninviting.

  "Are you angry with me, Professor?"

  Minerva sighed. "No, Miss Lovegood. I am not angry with you." She paused,
  then grudgingly said, "Sit down."

  Luna happily sat down, and came to the point of her visit. "I tried to make
  it happen again."

  Minerva bit back another sigh. "And?"

  "It didn't work."

  "Well, I'm sure if you just keep trying-"

  "I want you to show me how to do it."

  Minerva's eyes narrowed. "Do you think it is appropriate for you to interrupt
  me?"

  "No, ma'am." Luna sounded wholly unperturbed. "But I still want you to show
  me how to do it."

  "Out of the question." Minerva's reply was immediate.

  "Then why did you correct me for interrupting you before you said no?"

  A moment's silence, as Minerva floundered for an answer to the question. "I
  don't think that matters. I am not going to show you how to do it."

  "Why not?" Luna was, if nothing else, persistent.

  "Because it's inappropriate."

  Luna seemed about to ask why, in a child's maddening progression, then
  paused. "You've been watching me," she observed. "In class. Today."

  Minerva felt a flush rise up from her throat. So the child had caught her. "I
  always watch you. You're a troublesome child."

  Luna gave a tiny laugh. "But I would be so good for you if you'd let me."

  Minerva's breath caught in her throat. Could the girl possibly understand
  what she was doing to her? "If you were going to be good, you would do it
  without importuning me to immoral acts."

  A little shake of that delicately poised head. "I don't think that follows."
  Pale eyelashes veiled Luna's eyes, and then she said, "You told me it was
  natural. The pleasurable sensations."

  "They are," Minerva said, wondering why she didn't just send the girl to bed.
  "But it's not natural for me, or any adult, to engage in such activities with
  you."

  "Not natural, or not normal?"

  "Neither," Minerva replied sternly. "But mainly the latter."

  Luna gave a half-shrug. "I don't mind not being normal. I never was. Though I
  did try for a while." A long sigh, and she leaned forward, resting her elbows
  unself-consciously on her knees, propping her chin in her hands. "Professor,
  please. I wouldn't ask if I could work it out for myself. I promise I'll be
  good afterwards, if you'll just please show me."

  Worn out with arguing, Minerva allowed herself to be persuaded, though she
  suspected that Luna could have recited dirty limericks in that little silvery
  voice and it would have convinced her. "Very well," she said, standing up.
  "Come with me." She led Luna through to her private rooms, and as she led the
  child across the threshold murmured, "Alea iacta est."

  "I beg your pardon?" Luna said politely.

  "Nothing." Minerva eyed her bed, and Luna. She came to a decision. "Go stand
  facing the corner." There was a moment's hesitation, then Luna did as she was
  told, her obedience sending a small thrill through Minerva's body.

  Minerva stripped quickly, folding one by one her dress, her chemise petticoat
  and stockings. She pulled on a nightgown and dressing gown, then climbed into
  bed, propping herself up on a mass of cushions, drawing the down coverlet up
  around her. She paused for a moment, gloating over the sight of the
  uncertainty in Luna's posture, then said, "Come here, Miss Lovegood."

  Luna joined her on the bed, and required only a little tugging to be drawn
  into Minerva's lap, the soft coverlet between them. Luna gave a small sigh,
  and dropped her head back against Minerva's collar bone. "I like this."

  Minerva found that, once committed to the course of action, her impatience
  brooked no delay. Her long fingers slid delicately down Luna's sides, moving
  to cover one soft little hand warmly. With the other hand, she tugged up the
  hem of Luna's skirt, watching as smooth white thighs that had been haunting
  her dreams were revealed.

  When Luna's skirt was all the way up around her waist, Minerva began guiding
  Luna's right hand, moving it to rest on the soft frills of her new knickers.
  "Sometimes it feels pleasant to touch through the fabric first. Like this."
  She gave a soft squeeze, and was rewarded with a gasp.

  "Why does it feel so different, with you? So much better?"

  Minerva smiled. "Having a partner increases your anticipation, which makes
  you more sensitive to touch. You can, however, by knowing the right places,
  do it for yourself." She squeezed Luna's hand again, increasing the pressure
  on the soft mound.

  Luna pushed her hips up, turning her head slightly so that her breath was
  warm on Minerva's throat. "Under the knickers now? Please?"

  There was no way to deny her, and Minerva moved their joined hands to slip
  under the elastic. The wetness there was a pleasant surprise. "Rub the
  wetness over yourself. Like this." Minerva moved the fingers in a circular
  motion, so that Luna was coated in slick moisture.

  "Oh, yes." Luna's eyes had slid shut, and she was panting slightly. "So good,
  Professor."

  "Firm slow circles," Minerva whispered, guiding Luna's hand gently, almost
  ready to come herself from the sight and feel of the needy girl.

  "Faster?" Luna gasped, not begging, but there was a definite pleading note to
  her voice.

  "If you're ready," Minerva replied evenly, feeling Luna's hips rising and
  falling in a restless rhythm.

  Luna nodded, and then Minerva increased the pace, rubbing furiously, slick
  fingers sliding and bumping over the sensitive nub, until Luna gave a loud,
  keening cry, and came, her hips thrusting madly. Exhausted, Luna let her head
  fall back again, knocking painfully against Minerva's collar bone.

  Neither moved for a moment, and Minerva listened to the shallow breathing,
  savored the warm weight atop her, the slickness she could feel against her
  fingers. Slowly, she pulled her hand out of Luna's knickers, and wiped it on
  the coverlet, resolving to use a cleaning charm later.

 Luna gave a long, peaceful sigh. "Is there a name for it?" she asked
  absently, cleaning her fingers in the same manner.

  "Several. None I care to teach you, though." Minerva cursed herself for a
  hypocrite that she could bring the child to an orgasm, but not say the word.
  "You should return to your dormitory. It's very late."

  Luna didn't move. "I feel so good here, though. Like a baby crocodile
  sleeping across its mother's nose. Safe."

  Minerva stiffened. "You see me as a mother figure." She recalled that Luna
  had lost her mother, and wondered why she hadn't recalled that before.

  "No," Luna protested dreamily. "My mother was a remarkable woman, but the
  sight of her never made me want to run to the loo and touch myself."

  Minerva was aroused by Luna's bluntness, but didn't allow herself to yield.
  "Up," she said, in a voice that permitted no disobedience.

  Luna shifted languidly and climbed off the bed, looking at Minerva
  reproachfully. "You get so cross."

  Minerva stood up as well, and strode over to the bookcase. Looking over the
  titles, she found the one that all teachers were issued for students with
  sexual questions. "Here," she said, thrusting it at Luna. "If you have any
  further difficulties, you may refer them to this text." Belatedly, she
  remembered that the reason the book was rarely used was because most of the
  teachers found it excessively informative. Well, so much the better. At least
  she wouldn't have to deal with any more questions.

  Luna took the book, and left the room without a word, hurt at the sudden
  dismissal. What, she wondered, would she have to do to make Professor
  McGonagall be kind all the time, and not in fits and starts? She resolved to
  read the book thoroughly. Somehow, she would find a way.

  *****

  Three weeks passed before Luna came to Minerva again. Minerva, who hadn't
  entirely expected Luna to heed her directions to stay away, found herself
  almost shamefully disappointed as night after night passed without Luna
  coming to her.

  She told herself, sternly, that it was better, that the situation had been
  wrong in the extreme. All the same, she found herself watching Luna far too
  much. She watched Luna during class, letting her eyes devour the sight of
  Luna's tiny pink tongue emerging slightly as she concentrated on her
  transfigurations. She watched Luna during meals, eating her food daintily,
  but always sitting alone, at the end of the Ravenclaw table.

  One morning, she saw Luna in an unexpected place. On the Quidditch pitch,
  watching the Gryffindors practice. Minerva could think of no reason for her
  to be there, and was considering going and scolding her, and arguing with
  herself as to whether she simply wanted to scold the child so she could talk
  to her, when Harry lit down, and began talking to Luna.

  Minerva watched through narrowed eyes as Luna responded, giggling slightly at
  something Harry said, then reaching out to pluck a dead leaf off his robes.
  Without thinking about her motivations, Minerva stormed forward. "Miss
  Lovegood. Is there some reason of which I am not aware that you need to be
  here?"

  Harry looked surprised. "I asked her to come and watch us practice,
  Professor."

  "Watch you practice, or distract you? Miss Lovegood, I should think you have
  better things to do with your time than to hang about the Quidditch pitch,
  mooning over Potter. At least, you do if your Transfigurations marks are to
  be believed." The latter was a blatant lie. Luna was very good at
  Transfigurations, seeming to have an inherent understanding of the
  possibilities for transformation.

  Luna lifted her head, and gave Minerva a little smile. "I've already done all
  my homework this weekend, Professor. And Harry asked me to come watch."

  "Fine," Minerva snapped, and walked away. It frightened her how angry she was
  with Luna, how much she wanted to drag the girl off to her office and berate
  her until she cried, then kiss the tears away.

  *****

  It was that night, when she had given up expecting Luna to come, that she
  came. Maddening, typical behavior. "What do you want, Miss Lovegood?" Minerva
  demanded coldly.

  Luna sat down, this time, without waiting to be asked. "Why are you always so
  angry with me?"

  A pang of guilt assailed Minerva. It was true, she had been snapping at Luna
  constantly. First for seeking her out sexually, then that morning on the
  Quidditch pitch. She took refuge in her teacherly role. "Because you don't do
  as you're told."

  Luna nodded, twice, and looked pleased. "In that case, I wanted to ask you
  about this." She opened up the book that Minerva had given her, and slid it
  across the desk.

  Minerva looked, astonished, at a picture of a tiny witch with a man bent over
  her lap. She was spanking him vigorously, and both of them appeared to be
  very happy with the situation. "What did you want to ask?" she said, clearing
  her throat.

  "I want you to do it to me," Luna replied calmly. "You're always saying that
  I'm troublesome and disobedient, so I thought you should probably spank me."

  Minerva lifted her eyebrows, shocked out of embarrassment. "Miss Lovegood, a
  spanking is a punishment. One does not ordinarily seek them out."

  "The man in the picture looks quite happy," Luna observed. "And I know you
  won't hurt me too much."

  "And what makes you think that?" Minerva asked coolly, trying to stay calm,
  trying not to imagine Luna bent over her knee, squirming.

  "Because if it's you, it could never be too much." Luna spoke as one stating
  an incontrovertable fact.

  A rush of pleasure passed through Minerva at that expression of trust. She
  tried to hide it in sternness. "And I suppose if I say no, you'll badger me
  incessantly?"

  Luna dropped her eyes quickly. "I suppose so," she said quietly. She didn't
  like the thought that Professor McGonagall only did things with her because
  Luna badgered, but maybe she would think it was another good reason to spank
  her.

  Minerva stood up and walked around the desk, holding her hand out to Luna
  mutely. Luna stood and accepted it, then suffered herself to be led into
  Minerva's private quarters once again. "Take off your clothes," Minerva said
  calmly, sitting down in an armchair.

  Luna hesitated for half a second, then shrugged off her outer robes, hands
  flying to the buttons on her blouse, undoing them one by one. Quickly, she
  removed blouse and skirt, letting them drop to the floor. After an instant's
  hesitation, she took off her undergarments as well, and stood, naked, in
  front of Minerva.

  Minerva beckoned her over, and took a moment just to look at Luna, to drink
  in the soft curves of her body, the graceful lines of throat and waist. Her
  hands strayed to Luna's breasts, and she took one soft nipple between thumb
  and forefinger, pinching. The little gasp that Luna gave was irresistable.
  "Over my lap."

  Luna obeyed, feeling very, very naked. She squirmed around a bit, trying to
  find a comfortable position, but was deterred by a sharp slap on her bottom.
  "Keep still," Minerva hissed.

  Minerva watched the little jump that Luna gave in response to the slap, and
  issued another. She felt all the anger that she had felt that morning, rising
  up in her. Luna was just a typical teenager, senseless and flirting, but at
  that moment, she was under Minerva's power. Minerva issued another round of
  stinging slaps.

  Luna tried to keep quiet, but couldn't smother a little moan. Even though
  Professor McGonagall was hurting her, just being with her made Luna feel safe
  and comfortable. And the painful spanking was arousing her even more than she
  had expected it would. Luna squirmed again, trying to find purchase to rub
  against.

  "Hold still," Minerva repeated, spanking the soft thighs painfully, pleased
  with the little start that resulted. She continued until Luna's body began
  moving more away from her hand than toward it. A last hard spank evoked a
  small, mewing cry, that almost made her want to continue. She wanted to push
  harder, to bring out the whole range of sounds, whimpers, breathless sobs,
  little screams if she went long enough. But Minerva refrained. There were
  better ways to get what she wanted.

  Minerva let her hand trace over the reddened skin. "How does it feel?"

  Luna drew a deep breath, and tried to compose herself enough to reply
  properly. "It burns," she whispered. "Stings dreadfully. But it feels...so
  good."

  Minerva smiled, knowing that Luna was telling the truth. She felt fiercely
  possessive of the child sprawled heedlessly across her knees. "I'm glad.
  Because from now on, whenever I feel you need it, this is what you'll
  receive. It might be like this, or I might bend you over my desk and paddle
  you until you cry." Minerva let her mind play over all the different ways
  that she could spank Luna, each more delicious than the last.

  Luna gave a throaty gasp. "Yes. Oh, yes, please."

  Minerva reached down between Luna's legs, feeling the slick wetness coat her
  hand. The girl was soaking wet, and Minerva cupped her firmly in her hand,
  squeezing. Another little moan. "Has anyone else ever touched you here? Tell
  the truth."

  "Never," Luna said quickly, startled at being asked. "Only you." She tried to
  move, to shift the pressure, achieve the rhythm that she needed, but
  Minerva's hand was firm.

  "Not Potter?" Minerva squeezed a bit more tightly, making Luna whine and try
  to buck her hips.

  "No one," Luna assured her, breathlessly. "Oh, Professor, please..."

  Satisfied, Minerva moved her hand, thin fingers seeking out Luna's
  sensitivity, rubbing quickly. She watched as Luna's back arched powerfully,
  and after only a moment, Luna gave a little cry, a hard push with her hips,
  and then went limp.

  Minerva gently withdrew her hand, and rubbed Luna's back for an instant. "All
  right. You may get up."

  Luna made a small, abortive movement, then lay limp again. "I don't think I
  can," she sighed. "Take care of me, please?"

  "You need to go back to your dormitory. Your classmates will start to worry."

  Luna shook her head. "I don't always sleep there. No one ever notices.
  Sometimes I sleep in the Astronomy Tower. Let me stay here tonight."

  Minerva struggled with herself briefly. But the thought of having Luna for an
  entire night was all too tempting. "Very well." She helped Luna off her lap,
  and led her into the bathroom, sitting her down on the small bench there
  while she ran a bath. She noticed Luna squirming slightly at the pressure on
  her bottom. "Do you want me to heal you?"

  Luna shook her head. "No. I like it - like knowing that you did it."

  Minerva didn't answer, didn't trust herself not to reveal the possessive
  thrill that statement gave her, just finished running the bath, poured a bit
  of sweet orange oil into it, and helped Luna climb into the tub.

  Luna was passive, and quiet under Minerva's hands, allowing herself to be
  bathed like a small child. She moaned a little when Minerva parted her legs,
  washing gently between them, but Minerva just smiled and shook her head.
  "You've had enough for tonight."

  Luna wasn't at all sure about that, but subsided anyway. She was enjoying
  being taken care of so completely, and when Minerva tucked her into bed, Luna
  smiled up at her. "I like being with you so much."

  "Close your eyes," Minerva said gently. When Luna obeyed, she stripped off
  her clothes and put on a nightgown, then slid into bed.

  Luna snuggled up to her comfortably. "Why won't you let me see you?"

  Minerva wanted to say because it wasn't appropriate, but the things she'd
  done that evening made a mockery of that answer. The truth was, at over
  seventy, her body was not quite as perfect as it had once been, and next to
  Luna's supple, perfect curves, she was ashamed of her own lean body. "Just
  because."

  "Do you like to be touched, too?" Luna let her fingers trail suggestively
  over Minerva's ribs.

  "Yes," Minerva said cautiously. "But you needn't."

  "I want to. Please?" The girl's hand crept lower, under the covers.

  "If you want," Minerva said, jerking slightly as Luna's hand brushed a
  sensitive spot on her lower stomach.

  Luna rucked up Minerva's nightgown. "You're not wearing any knickers," she
  said, her tone faintly accusing.

  "One doesn't always when going to bed." Particularly when curling up with a
  sexually insatiable teenager, Minerva added mentally.

  Luna slipped her fingers between Minerva's thighs, finding the slickened
  clitoris easily. "I've been practicing," she said conversationally.

  "I can tell," Minerva said, her voice slightly strained. Her eyes were
  tightly shut, and her breathing came quickly. "Love...can you put two of your
  fingers inside me?"

  Luna pressed a soft kiss to Minerva's shoulder. "Of course I can." She gently
  pressed two fingers to Minerva's entrance, and let them slide slowly in.
  "Like this?" She wiggled the fingers experimentally.

  "Yes..." Minerva's voice was high and breathy, as no one had heard it in
  years. "Push them in and out...oh, Merlin, just like that!" Her head tossed
  on the pillow as Luna followed her instructions enthusiastically. She reached
  down and caught Luna's hand forcefully at the wrist, increasing the pressure.

  Luna watched her, enraptured. She'd been faintly embarrassed about her own
  reactions to touching, but it seemed that Professor McGonagall liked it just
  as much, if not more. "Do you like it, Professor?" she whispered.

  "So much," Minerva gasped, pushing up against the little hand. "Oh, Luna,
  feels so good, right there, oh..." She gave a convulsive shudder, then
  relaxed, tugging Luna's hand away. "No more now."

  Luna cuddled up even closer, still letting her fingers comb through the thick
  curls. "Does it feel nice with them inside?"

  Minerva gave a little laugh. "I think I just demonstrated quite clearly that
  it does."

  "Will you do it to me like that?"

  "I don't really see the need," Minerva said pensively. "You come in about
  three seconds as it is."

  "But I want to try it," Luna persisted. "Please?"

  "All right," Minerva sighed, easily persuaded, as always, by Luna's
  entreaties. She shifted their positions so that Luna was flat on her back.
  Her hand deftly parted the smooth thighs, and she was surprised to find Luna
  wet once again. "Insatiable," she murmured, and probed Luna gently with one
  finger. "How does that feel?"

  "Odd. Not bad, though." Luna shifted a bit as the finger twisted inside her.
  "Another one?"

  "I don't want to hurt you," Minerva whispered, but complied all the same,
  carefully working another finger in. Luna whimpered, and Minerva frowned.
  "Does that hurt?"

  "No - yes - I don't know. Don't stop. Please." Luna spoke in fits and starts,
  and her brow was furrowed. As Minerva's fingers curved, she moaned and her
  hips shot upwards. "Fuck," she whispered, awe-struck, her whole body
  straining.

  Minerva was thrilled at the sound of that tiny obscenity, the first she'd
  ever heard Luna use. She increased the thrusting with her fingers, watching
  as Luna twisted, her body never relaxing, craving more and more.

  Luna took a deep breath, and one more hard thrust brought her over the edge,
  causing the breath to be expelled sharply as a flood of pleasure washed over
  her.

  Minerva withdrew her fingers, and pulled the shaking little girl close.
  "There, sweetheart. It's all right."

  "So good," Luna murmured against her shoulder. "You always make me feel so
  good."

  "Go to sleep now," Minerva whispered, trying to push down the impulse to joy
  inside her.

  Luna nodded, and within moments, her breathing had evened out. Minerva
  watched her for a little longer, then allowed sleep to claim her as well. She
  had never slept better.

  *****

  The next morning, Minerva awoke to Luna pulling on her clothes. A glance at
  the clock confirmed that it was still quite early. "You're up early," she
  observed, rubbing her eyes, missing the warm weight of Luna's body against
  hers.

  "It's a Hogsmeade weekend," Luna said happily. "And I promised Harry I'd go
  with him."

  Minerva's spirits plummeted. After a night like that, Potter was still all
  that Luna could think of. She didn't bother speaking, just closed her eyes
  again, willing the hurt to leave her. It didn't.

  Luna finished dressing, and moved awkwardly towards the silent figure on the
  bed. "Thank you, Professor," she whispered, leaning down to kiss Minerva on
  the cheek. There was no response, and Luna frowned slightly, then left. She
  couldn't imagine what on earth was wrong.

  *****

  For the next few days, Minerva ignored Luna utterly. She caught beseeching
  little glances being cast at her occasionally, but she paid no mind. Quite
  apart from her feelings for Luna, Potter was one of her students, and she
  doubted he would thank her for molesting his girlfriend.

  In Transfigurations class on Wednesday, however, Minerva spotted something
  that blew all of her good intentions right out the window. Ginny Weasley
  leaned over to whisper something to Luna. The blonde responded by taking
  Ginny's hand in her own, and giving her a deep smile.

  "Miss Lovegood! Miss Weasley! Five points from both your houses for
  inattention. Miss Lovegood, you will stay after class please."

  "That's not fair!" Ginny exclaimed.

  Luna merely gave a dreamy smile. "Yes, Professor." And then she gave Ginny a
  reassuring smile that made Minerva's blood boil.

  After class, Minerva wasted no time in leading Luna into her office and
  locking and soundproofing the door. "Bend over the desk. Now." Her voice was
  harsh.

  Luna looked faintly anxious, sensing the hostility in Minerva's voice. She
  did as she was told, however, bending over the desk quickly, drawing up her
  skirt.

  "Did I tell you to take your skirt up?" Minerva demanded. "Or has it become
  habitual with you?"

  "No, Professor..." Luna bit her lip. "Shall I put it down?"

  "No." Minerva stepped forward and hooked her fingers into the waistband of
  Luna's knickers, drawing them down to the knees. Luna wiggled a bit. "Hold
  still."

  Moving around the desk, she opened a drawer, and found the paddle. Though
  corporal punishment was no longer used at Hogwarts, Minerva had saved her
  paddle, more because she had forgotten to be rid of it than for any conscious
  reason. She hefted its weight in her hand, and moved to stand behind Luna.
  Without speaking, she brought the paddle down hard on Luna's bottom.

  A little gasp was the only sound Luna made, but she braced herself against
  the impact. Minerva continued pitilessly, hating the impulse in herself to
  hurt, yet needing some outlet for her anger. How could Luna come to her,
  asking so much, and then be so intimate with the other students? How close
  was she to Ginny? Had they already touched each other, kissed?

  Minerva was distracted when a little choked sob issued from Luna's lips, and
  she could see that the girl's face was covered in tears. Yet still she didn't
  move, didn't try to pull away. Minerva winced as she looked at the burning
  raw skin of Luna's backside. She laid the paddle down on the desk and stood,
  looking down at Luna's lightly trembling figure.

  "Touch me," Luna moaned, and a wave of anger passed through Minerva. That was
  really all Luna wanted then, sexual gratification. She let one hand drift to
  Luna's bottom, and began dragging her fingernails, slowly, across the
  reddened skin, hard. A little half-scream was her reward, and Minerva felt a
  sinful thrill of satisfaction at it.

  "Touch me," Luna repeated, her thighs parting slightly. "Please,
  Professor..."

  Minerva stepped back. "Correct your clothing, Miss Lovegood."

  Luna stood up, pulling up her knickers, letting her skirt fall down. Her face
  was flushed, both aroused and unhappy, but she didn't hesitate to move close
  to Minerva, press her lips to the older woman's throat. Her tear-damp face
  was warm against Minerva's skin. Stammering words began tumbling from her
  lips. "I didn't - don't - please - love - I can't - sorry..."

  "Calm down," Minerva whispered once, then said it again more strongly. She
  pulled out a handkerchief and began wiping Luna's face roughly. "You need to
  go to your next class. Do you want a note?"

  Luna shook her head, swallowing hard. She turned and walked to the door, her
  posture a study in misery. At the last moment, she turned and looked back,
  her eyes wide and unhappy, but with such love in her expression that it took
  Minerva's breath away.

  Minerva stepped forward, and took Luna by the arms. "Meet me by the lake
  tonight at midnight, understand?" She hadn't meant to say that, didn't know
  why she had, and yet she knew that she had to settle this once and for all,
  before she destroyed both of them.

  Luna nodded, her expression lightening just a trifle, though she still looked
  cautious. "I promise." She left then, hurrying off to Potions class, where
  she lost ten points from Ravenclaw for being tardy.

  *****

  Minerva strode down to the lake, determined to tell Luna that it was over,
  that there would never again be anything between them. It was only fair. Luna
  was young, and clearly confused. She didn't need to be tied to a jealous
  older woman who could do nothing but hurt her. But then there was the memory
  of Luna's tearful face pressed against her neck, the hesitant lips against
  her skin. In fact, she really had no idea what she was going to say to Luna.

  The cool evening air made her shiver, but she forgot that when she saw Luna's
  blonde hair shining in the moonlight. Drawing closer, she saw that the girl's
  skin seemed to almost radiate the same silvery glow. Luna was made for
  moonlight, and Minerva felt a fierce satisfaction at having discovered that.
  "Take off your clothes." She wanted to see every inch of Luna's body bare and
  glowing in the dim light.

  Luna blinked, and looked sorrowful for a moment, but pulled them off, letting
  cloak, robes and all fall to the ground. "I don't understand," she whispered,
  almost to herself.

  Minerva wanted to say that neither did she, but that wasn't wholly accurate.
  "Tell me what you're doing. You come to me one night, and the next day you're
  off with Potter. Then you're touching Ginny in class. Tell me what you want."
  She wasn't aware of having moved forward, but then Luna's plump arms were in
  her hands.

  Luna looked surprised, and then a serene smile crossed her face. "I want you.
  Harry's scared. And he likes to be with me because I'm not scared, and that
  makes him feel like things are going to be all right. And Ginny's my friend,
  but not like that." She shivered a little bit, but didn't try to move at all,
  just stood there naked in the moonlight, smiling.

  "You're telling the truth?" Minerva shook her slightly. "You don't want
  Potter?"

  "No." Luna pressed herself close to Minerva's body, slipping her arms under
  the cloak to wrap around her lover's waist. "I only want you. Minerva.
  Please..."

  Hearing her name from Luna's lips brought down all her defenses, and Minerva
  wrapped her arms around Luna's shivering body, tugging the cloak up to cover
  the naked body. "I love you so much," Minerva whispered. "I didn't want to, I
  knew it was wrong, but you kept coming back, you wouldn't stop..."

  "That's because I love you too," Luna replied placidly, and then she stood up
  on tiptoe, and pressed her lips softly, slowly to Minerva's.

  They stood like that, unmoving for a moment, and then Minerva took control of
  the kiss, deepening it, exploring the hidden recesses of Luna's mouth. Luna
  gave a little sigh, and began pressing herself closer to Minerva. When the
  kiss broke, she rested her head on Minerva's shoulder, panting slightly. "All
  day, I kept thinking about you. Because I didn't know what was wrong. And I
  wanted you so much...please?"

  Still dizzy with relief, Minerva could deny her nothing. She let one hand
  drift down Luna's back, cool fingers encountering skin that still burned from
  the morning's brutal punishment. "Forgive me?" she whispered.

  "Only if you'll do it again sometime," Luna smiled, letting her thighs slide
  apart, lifting up onto her toes, and leaning forward to balance against
  Minerva's body. She burrowed underneath Minerva's cloak, seeking out the
  warmth of the firm body against hers.

  Minerva laughed unsteadily, and slid her fingers into Luna's wetness. The
  girl was hot against her cool fingers, and she warmed them there, exploring,
  letting her fingertips seek out the sensitive clitoris. An insistent moan
  signalled her success, and she smiled, pressing down firmly.

  An entire day's arousal had left Luna even readier than usual, and she moaned
  again, lifting one knee to twine it around Minerva's legs, as if she were
  trying to climb her. "Oh, please, Minerva, please, love you so much, I need
  you..." And then her words devolved into a series of sounds, whimpers, and
  then a muffled scream as she buried her face in Minerva's shoulder.

  Luna's knees gave way, and Minerva, unprepared, dropped to the earth with
  her, still hugging her close. "Everything's all right now," she whispered.
  "Luna. Sweetheart."

  "I know," Luna sighed, lifting her head to place a tiny kiss below Minerva's
  ear. "It always was, really." And then she moved slowly, pulling on her
  clothes, allowing Minerva to help her to her feet. "Can I sleep with you
  tonight?"

  "Yes." Logistics, proprieties, those could all be worked out the next day.
  Tonight, Luna was hers.

  "Do you think Professor Dumbledore would give me a job when I leave school?"
  Luna asked dreamily, her hand slipping into Minerva's. "Or I suppose I could
  just stay here as your concubine...you'd like that, wouldn't you? I just want
  to be with you, you know. Forever."

  "Forever," Minerva said firmly, and together, hand in hand, they returned to
  the castle, and the warm bed that fit them so well. Forever.
