And so, next Monday…

Three days before Monday did pass without much happening. Harry decided not to act too hastily and wait for realisation of this part of his plan, before doing something else. So, these days he was doing schoolwork (it was very tempting to let Hermione do it for him, but Harry resisted such urge) and having fun. The only thing that now he could have a… different kind of fun.

He did ask Hermione to adapt coins left from D.A. so that he could contact his three girls when he wanted. So, he several times invited one of girls into empty class and they all were very happy with the result.

During one of such session Luna did speak about her problems and Harry felt great shame after that: girl was still bullied by other members of her house. He knew about it, after all they spoke about it at the end of last school year but… he forgot about it, too much his own troubles. But not this time! He did say, that he’ll take care of what is his, and he’ll do it!

And so, with the rational use of Marauder Map and Hermione’s ideas they made so that a bully tried to worry Luna just as professor McGonagall passed nearby (thanks to Ginny). Harry was somewhat pissed, that his head of house acted so decisively to protect a member of another house, while has never really done anything to help him, when he needed it. Another reason for him to say: “Fuck you!” to the magical world. Either way, bully got literally caught by the ear and dragged to Flitwick. Little man was pissed and acted as a head of house should, so now part of bullies has other things to do and to think about, and those who escaped the punishment are just scared.

And now week-end was over and soon it will be the time to act!

In Hogwarts Library, in the restricted section to be more precise, three young women sat around the table. Nothing particular or noteworthy, students in higher years of Hogwarts often need the knowledge there. Moreover, one of these young witches was Hermione Granger the ever-studious Gryffindor, who spend the big part of her free time there. Ginny Wesley and Luna Lovegood with her were one year younger and didn’t take their studying as seriously but once again there was nothing strange there. The first supposition that anyone from the outside would have while looking at them would be that younger girls asked for help in some project.

And they would be wrong. Because in reality it was Hermione who roped others two into helping her realise her little personal project. On the other side, younger girls didn’t need much convincing, as soon as she explained her plan they gleefully joined and already put forwards many interesting ideas.

Master asked her to modify the old Galleons they used last year for D.A. so that he could contact them when he needed their service. Of course, she did what she was ordered, but she couldn’t help but feel that is was not enough, master deserved better. So, she’ll give him better. And right now, while their master was busy elsewhere and didn’t needed them, girls were working hard.

They would do it, and their master will receive their gift as proof of their love and loyalty.

Harry could hardly keep his excitement in check, so his today’s school work suffered, but it’s not easy to concentrate on your spellwork, let alone potions (Snape had a field day in the morning), when you expect such event in the evening. As the result, even in DADA he nearly botched the counter curse they were working on. On the other hand, it gave a perfect excuse to remain after the bell.

Hermione was one the last to go, she gave him nearly imperceptible nod, confirming that she would guard against unwanted visitors. And so, once they were only them in the classroom, Harry approached Tonks.

“Wotcher Harry,” she greeted him.

“Tonks,” he knew that she hated when he addressed her as ‘professor’ at least out of classes. “I fear I didn’t entirely got the sense behind today’s spell. Could you help me?”

“But of course, ask away!”

And Harry did ask, while he released the pheromone of Sirius. The effect was nearly immediate. Tonks blinked once, twice, her eyes clouded and she begun to disrobe. She clearly didn’t notice it, as she was still explaining in details the curses that the spell could help against and the best way to cast it. Harry was also discarding his clothing, but he was fully conscious about what he was doing. Either it was because he better controlled his power, or just because he was doing it willingly and knowingly.

“So, the most important and useful aspect of this spell is the fact that it can be used both to protect from the curse or reverse it, if you or someone else is already cursed,” Tonks was already naked and lied down on the desk, giving his easy access to her pussy. All the while she actively gesticulated showing the best way to wave the wand.

“It’s really so important? The fact, that spell can prevent damage as well as heal it?” Harry voiced his surprise, while thrusting his cock into his teacher.

“Oh yes!” It seems Tonks didn’t even feel that she was penetrated. “In battle this fact is decisive, and can be the only factor that separate someone who survived and who died!”

Harry conceded the point and asked more clarification about others things, Tonks was happy to answer. And during this discussion Harry was still pounding in her with will. It was funny to see her gasping and moaning in ecstasy in between of her words without noticing it.

Felling his climax near, Harry shoved his length into her cunt as far as he could and let out spurts of cum as he orgasmed. Tonks eyes immediately cleared.

“Harry, what is going on?” she begun to ask, as she became aware that she is lying on her desk, naked, and her pussy is penetrated, overflowing with cum…
