Chapter 21

Following an intensive study session in which Harry proved that yes, he did indeed seem to have a talent for Runes, the Gryffindor duo went to the Great Hall for lunch. They were talking about their teacher, Professor Babbling, and what test she might have prepared when a furious looking Professor Snape entered the large hall.

"Potter! Where were you and your girlfriend?" he raved as he stalked inside.

Harry ignored him as he handed a bread platter to Hermione. "I wonder if Professor Babbling will give me that test today?" he asked her.

"Potter! Don't you dare ignore me!" Professor Snape walked closer and made to grab Harry by the arm.

Quickly, thanks to his Quidditch reflexes – and years of abuse by his fatter and stronger cousin – Harry twisted away, and now faced the unpleasant man.
"Keep your hands off me, Snape," he snarled back.

"Detention, Potter. And your little girlfriend as well," Snape stared him down.

"Stuff it up your cauldron. I'm not going to detention with the likes of you," Harry countered. Snape turned red and went for his wand.

"What is going on here? Severus, put your wand away!" Tonks said as she walked up to them.

"Potter and Granger here decided to skip Potions class and now talk back and refuse to accept the fact I've given them detention," Snape informed her.

"Mr. Potter, Miss Granger, why exactly were you not in Potions class?" Tonks asked them.

"Dumbledore called us for a meeting that caused us to miss Charms and the start of Potions, and since Snape hates my guts I doubt he would have let us come in late as it is. So instead Hermione tutored me a bit in Runes," Harry explained.

"That's Professor Dumbledore, Mr. Potter. Still, that is no excuse to skip the class completely. I think Severus was right to assign detention to you," Tonks said after a moment, then allowed a small grin to show. "Severus, do you mind if I add that detention to Mr. Potter's back log he has with me? I can use someone to repair the training dummies the sixth and seventh years destroyed."

"Perhaps hard labour will teach the brat to hold his tongue. I accept," Snape told her, then gave her a nod, Harry a sneer, and walked off.

"Detention tonight then. You know the way, Mr. Potter," Tonks said in a haughty tone, but her eyes were sparkling. Harry pretended to be annoyed as he turned back to his food.

His guess that Professor Babbling would have a test for him in Runes proved to be right, and he spent the full hour working through a modified version of the end of year exam Hermione and his other new classmates had had to take the previous year. When the hour was over and they had to leave for History of Magic he had only just completed it when he had to hand it over.

"How did you do? Did you remember that Sowilo can mean both Wholeness and Success?" Hermione quizzed him.

"Yes yes, and that it is supposed to guide the energy flow to the Hvel as well," Harry commented. "Merlin, that was a hard quiz. Are they all like that?"

Hermione laughed. "Oh no, usually we just have to work on a sequence. In fact, that's what we were doing today. I'll show you later if you like?"

"Thanks, appreciate it," Harry smiled back at her, giving her a quick hug before he walked off again. Momentarily Hermione felt weak in the knees as she remembered the previous night.

"Oh Harry," she softly said, looking at his rear side as he walked off before she grounded herself and rushed to take his side once more.

History was their last class of the day and they worked on their homework following dinner, until time for the 'detention' came. To his surprise, Harry found Hermione following him into the corridor.

"What are you doing?" he asked her.

"Professor Snape assigned us both detention, didn't he? And you wouldn't let me be alone with him in the dungeon now would you?" Hermione pointed out.

"Yeah, but..."

"Come on, Professor Tonks will be waiting for you," Hermione grabbed Harry's arm, and pulled him along. Not willing to argue in the corridor where a prefect or one of the professors could come across them at any moment, Harry just went along.

"Come in," Tonks called out when Hermione knocked on the door. She stepped through first, and found her DADA teacher wearing a skimpy negligee only.
"Oh!" they both said at the same time.

Harry followed Hermione, and froze in the door opening, allowing his eyes to roam over his older girlfriend's body. "Wow..." he said.

"Shut the door Harry, you don't want someone else to see do you?" Hermione said. "Hello Miss Tonks. That is a sexy outfit, it really shows off your body."

"Wha... Harry... Hermione, what the hell are you doing here?" Tonks finally found her voice again, deciding to tackle the issue head on.

"As I told Harry, you took over our detentions with Professor Snape. Our, so mine as well. Harry, follow her to her personal quarters and I'll just be here revising until you finish, okay?"

"Errr... Nym?" Harry hesitated near the door still.

"We'll talk later okay, Hermione?" Tonks waited until Hermione nodded, then took Harry by the arm and guided him inside her bedroom.

Once the door closed behind them, Hermione put away the book she had taken out of her bag, and rummaged in it, taking out Harry's invisibility cloak. She covered herself in it and then cast a silencing charm on herself. Hidden and silenced, she walked to the door connecting the DADA classroom to Tonks' personal quarters, and opened the door a little. Through the gap she saw Harry and Tonks kissing, and took the chance to slip inside the room, closing the door behind her.

There was a chair in the corner near the door that had nothing on it and she sat down in it.

"When did you become such a great kisser?" Tonks asked, licking her lips after they broke off.

"I have a wonderful teacher," Harry replied. "And I just love kissing you..." To prove this, he began laying a trail of kisses down her neckline that led him to the top of her breasts, covered only by the flimsy material of her nighty.

"Oh, hero, that feels so good," Tonks nearly purred. "Get those clothes off love, I want to see what's mine."

Harry quickly stripped, then Tonks guided him over to her bed. They lied down side by side, until he rolled slightly over her and kissed her again. As they kissed, his hands started moving her negligee up. Tonks raised herself a little to allow him better access, and soon it was over her head and gone. Harry moved his head down to kiss her breasts, starting with the right one.
Tonks moaned at the sensation on her nipple. Feeling the need to return a little, she reached down to grab Harry's semi-hard member in her left hand and softly began pumping it. Harry proved he knew her body well by moving to her left nipple before her right one got sore. Tonks let out a gasp of delight when out of nowhere his fingers were thrust into her.

"Oh! That... that feels wonderful," she commented. He managed to hit that special spot near the top that turned her insane, and she moaned deeply, forgetting to do anything with his stiff prick. Harry pumped his fingers in and out a while, driving her mad, until he removed his hand quickly and placed it on her clit.

"Oh Harry! Yessssssss..." Tonks arched her back, then moved her left hand on top of his, trapping it in place. He rolled the little nub and softly pinched it, causing Tonks to let out a deep moan and finally she shuddered, her juices splattering all over their arms as she came.

"I want you in me," she managed to say when her strength returned. Harry needed no further prompting and moved back over her. She reached down to guide his cock where she wanted it and both moaned as his firmness parted her folds.

Across the room, Hermione had three fingers of her right hand inside her soaked knickers, and her left hand was pinching her right nipple as she furiously masturbated to the sight, imagining it was her in the bed with Harry. Somehow she managed to pace herself to keep herself on the edge. When she saw Harry shudder and heard him moan, followed by Tonks letting out a very contented moan, she pinched her clit and that brought her over the edge as well. Unknown to the couple on the bed, their voyeur came at nearly the same time as they both did.

Her legs weak below her, Hermione looked on in envy as Harry's member moved out of Tonks, allowing a small white pool to form below her.
'I love you, Harry,' Hermione thought, making her way stealthily for the door.

Harry left Tonks' bedroom more than a quarter hour later, looking like the Boy-Who-Shagged. Hermione sat in the same chair she had been in when he had left her, a book in her hands, and looking as prim and proper as always. "Have fun?" she asked him.

"Errr... yeah. Look, Hermione, don't tell anyone okay?" Harry begged her with his eyes.

"Don't worry, I won't say a word. I'll cover for you both even," Hermione promised. She started putting her book away as Harry walked closer to her.

"Thanks, you're really a good friend," he said, smiling.

"Let's go back to Gryffindor Tower then," Hermione proposed. Harry was a bit surprised to notice her skirt had a large wet spot as she rose, but since he knew he didn't exactly look like a proper student right now, he didn't comment on it.

Tonks was in her bed, sleeping the sleep of a well shagged woman. When she would wake hours later, the soaking wet chair in the corner had already been cleaned by the same House Elf who made it his job to keep her room clean, Dobby.

The following day at breakfast Susan Bones 'accidentally' bumped into Harry as they entered the Great Hall, and when he got to the Gryffindor table he found a piece of parchment had been pushed in his pocket. Following Herbology he had a free period while Hermione went off to Arithmancy, and he returned to his dorm room to read it.

It was a letter from Amelia Bones, Susan's aunt.

'Mr. Potter, Harry,

I owe you an apology. I tried to keep Madam Umbridge under lock and key until we could interrogate her, but somehow the Minister found out she was being held at the Ministry. He abused his powers to force her release and ordered me to stop the investigation into the Blood Quill. The good news is, he had to do this officially so I now have evidence on parchment that Fudge is abusing his position. Combined with the still ongoing investigation in the 'former' Death Eaters, the noose around his neck is tightening. It really irks me that we could not find the Blood Quill itself – unless she had a head warning somehow, we must assume someone else at Hogwarts is helping her. I think you know very well who my prime suspect is.
For now, keep your head down and do your best to ignore Madam Umbridge. I will keep you informed through Susan if anything changes. Make sure to destroy this message as well – the person who is intercepting your owl post cannot learn you have another way to get in contact with me.'

Harry frowned as he used a small 'Incendio' to burn the paper. Dumbledore helping Umbridge made no sense, did it?

Professor McGonagall was wondering the same thing. "Albus, what are you doing with those things?" she asked, pointing out a small wooden case holding two long, black quills.

"Never mind that Minerva, that's between Dolores and I," Professor Dumbledore answered her.

"Albus, are those Blood Quills? Is that why Dolores was arrested Wednesday?"

"Yes to both accounts. As for why I have them, I couldn't allow the Ministry Aurors to find them now could I?"

"Why on earth not? Don't you want her gone from this school?" Professor McGonagall looked confused.

"Oh, I do. But not when she can so easily be replaced by someone more subtle. Can you imagine what might happen if someone like Selwyn or Lucius Malfoy would be the next person Minister Fudge brings forward? No, this way Dolores knows I have the proverbial sword hanging over her head, and she will think twice before trying another stunt like that." Professor Dumbledore looked pleased as he closed the box, and put it in a desk drawer.

"I hope you know what you're doing, Albus," Professor McGonagall said, still looking doubtful.

Tonks had a worried expression as she sent off her last DADA class of the week. She had wanted to show how dodging could help a skilled dueller survive a fight, but when she tried to morph into a smaller breasted form to do so – seriously, while she appreciated how much Harry liked her natural big ones, smaller breasts were much easier to deal with – she found her magic resisting the change. That combined with the general feeling of something being wrong prompted her to accept the possibility she had come down with something.
She knew Poppy Pomfrey seldom came down to the Great Hall for dinner, so she went straight for the Hospital Wing instead of grabbing some food.

"Hello, Nymphadora. What brings you here?" Poppy was preparing smaller Potions doses in her office and looked up as the metamorphmagus teacher knocked on her door.

"Could you do a general check maybe? I'm not sure, but something seems to be off," Tonks said. She explained the things she had noticed over the past few days.

Madam Pomfrey cast a few wordless charms over her colleague, making 'hmm' comments to herself as the results indicated something only a Healer would understand.
"Are you seeing someone at the moment, Tonks?" she asked suddenly.

Tonks looked at her quizzically but seeing no reason to lie, she answered, "Yes... we're very much in love. I see him every chance I get."

"I thought as much," Madam Pomfrey said. "Well then Tonks dear, I think you and your lover need to have a chat."

"What about? Do I have... an S.T.D.?" Tonks nearly whispered the last part, blushing.

Madam Pomfrey stared at her, then broke out in laughter, "S.T.D.? Oh, that is hilarious! No, nothing like that... you, my dear, are around two months pregnant. I suggest you and the father have a long chat about your future plans at the earliest opportunity."

"Pregnant... how could I be..." Tonks stumbled back, found a chair, and sat down. 'My mum is going to kill me,' was her first thought, immediately followed by, 'Oh Merlin... how can I tell my Harry?'
