His power is strong! His power in swift! His power is wonderful!

At first Tonks eyes were clouded, as she was under pheromone effect, and lived in some kind of fantasy where she explaining her favourite student details about the spell.

Then her eyes cleared and were full of panic and fear, when she snapped out of her trance and realised where she truly is.

And a couple of seconds later her eyes filled with joy and peace, when she became a ****. She, Nymphadora Tonks was a ****, and Harry Potter was her beloved and dear master. And he had just fucked her hard, which was the very best thing that could have happened. She felt him withdrawing from her and was greatly disappointed, but her master knew best what to do. She turned on her back, so that she can see him.

“Master, what can do for you?” asked Tonks, looking up at him adoringly.

“Oh, I’ve some ideas,” Harry smiled back, happy to see her submission and willingness to obey. “And I hope you will help me to achieve it.”

“Anything for you, master!” eagerly nodded teacher, and then tilted her head interrogatory. “But… may I ask, what happened?”

“Recently I’ve gain ability to produce the pheromone of Sirius,” he didn’t see any reason to hide it from her. “Any woman to receive my cum become mine.”

“Yes, I’m yours,” confirmed smiling Tonks. “Thank you for making me your ****, my master!”

“You are welcome,” smirked Harry putting back his underwear. Auror seemed little disappointed, that there would be no second round, but followed his example. “As for what I need you to do…”

“So, the additional practice in battle spells?” asked Hermione in one of many empty classrooms of the castle.

“That’s it!” confirmed Harry. “Next lesson Tonks will announce, that we need more practice and that it’ll be easier with smaller groups, so that she’ll randomly chose four students to work with them in the evening. And of course, in the first four there’ll be both of us and them as well,” Harry smiled darkly.

Once he gave instruction to his new accomplice, Harry bid her good evening and left – Tonks had some teacher obligations to attend to. Hermione was dutifully waiting nearby, being ready to prevent anyone from crashing her master’s party. They went away together, but before going back to the tower Harry decided to go once again over the next part of the plan. Hence them being alone in this empty classroom. And Harry DID lock the door this time and even added silencing charm.

“So, your plans are proceeding well, master,” stretched her words Hermione, while stretching herself in the most seductive way possible.

Hogwarts robes were doing a very good job hiding the… improvements in her figure, but at this moment her new curves were undeniable and very attractive. Harry felt his pant getting too cramped for his little friend, who was not so little now. It seems that his time with Tonks was enough to satisfy him today.

“Are you trying to seduce me, Hermione?”

She smiled guiltlessly and putted hands on her robes buttons, wordlessly asking for permission. Harry just smiled and begin to work on his pants. It seems their return to the dorm will have to wait a little more. His pants decided to be somewhat difficult this time and he had to concentrate a little before pulling them down. Once he looked back at his friend she already did removed all her clothing – it would seem she gained a great proficiency in that task. And her lips at this moment were so kissable, that Harry just couldn’t resist.

As their lips met and their tongues engaged the fierce battle for dominance reached down with one hand, slid a finger inside her, finding her wet and ready for him. He picked up his **** and pushed her up against the wall. She raised her legs and wrapped them around his waist while wrapping arms around his neck. Then, breaking off the kiss, she looked into his eyes as she sank down onto his cock, her cunt lips parting and stretching at the penetration. Her breath coming out in wordless moans and gasps, Hermione held on and moved slightly in Harry's arms as he carried her to the nearest desk. He laid her down and pulled out of her so he could finish undressing. Hermione moaned at the loss of the feeling of being filled by her master as he did so, but he was rapidly undressed, and he came back, passionately kissing her as he slid his dick back into her welcoming pussy. He thrust into her a few times, then got a glint in his eyes and rolled over, placing her atop him and commanded her in a demanding voice, "Ride me."

She pushed herself up off his body, so the only point of contact between the two were their hips and she began grinding her cunt against him on every downward thrust. He brought his hands up, cupping her full, firm breasts, running his thumbs across the nipples. She rode him until he came within her, making her cry in ecstasy as she orgasmed.

They needed some time after that to clean themselves and then return to Gryffindor dorm. The day was well spent.
