Plot setting: minimum

Andromeda never was cut off from the Black family, and tonks never joined the Aurora corps

It was the Sunday before classes started up for the year, and Harry was Plotting on who he would take next. He had thought about it for a bit now, of course while still fucking Daphne Astoria and Cassandra into submission every night, and one girl had caught his eye. Professor Tonks, a beautiful woman in her very early 20's, was too gorgeous for Harry to pass up. He knew she was his cousin of sorts, now that he was Lord black and tonks was a daughter of house black, he felt a family connection to her through his title. He didn't think much of it, all he could think about was the sexy professor he'd soon control.

He was walking down the hall of the 5th floor when he noticed the girl of his thoughts walk past him, giving him a smile as she did so. The two hadn't talked yet, but Tonks obviously knew the Lord of her house. Harry watched her as she past, eyeing the way her ass jiggles up and down. He looked around and saw no one else was in the hall, so he silenced his steps with a wave of his hand, and quickly followed Tonks down the hall.

He followed her to what looked to be an abandoned classroom, and followed her inside, confused what his professor could be doing. He disillusioned himself and saw Tonks walk up to a plain wall, "Professor Tonks wishes to enter" Tonks states, and as was the same with the room of requirement, a door appeared out of nowhere, allowing Tonks to open the door and enter the room behind it. Harry quickly followed, making sure to not touch the door as he did so. He looked around the magic room, seeing that it was a huge bathroom in the style of a swimming room. A hot tub lay in the corner, along with a big round bath in the middle and showers on the sides. Towels hung from racks to the right of the room, while toilets were on the left.

He saw Tonks start to strip, until she was completely naked in front of him, unaware of her spectator. Harry saw the beautiful form of the woman, seeing her luscious tan body that will soon be his, her cute tan bubble butt, her pink, shaved pussy and big creamy mounds fit with red areolas. Last but not least, the woman's beautiful and sexy heart shaped face, with full pink lips he knew would be around his cock soon.

Tonks stepped into the prepared bath and sank down, signing as she felt the water envelop her naked skin. Harry, seeing this as his distraction, quickly took the pendent off his neck and became visible again. He waved his clothes off and silently snuck up on his young professor. When he was right behind her he held the pendent to her eye level, and spoke.

"You're so hot Professor Tonks" He said calmly, instantly catching the girls attention. Tonks screamed in surprise, turning around quickly to see who it was, and that was the last thing she'd ever see as a free woman.

Harry saw Tonks go into the trance, and spoke the words he had spoken 4 times already. He added that she would help him control her mom one day, and ended the trance. Tonks awoke from her glazed condition before adopting the same submissive look in her eyes. Harry entered the bath and sat opposite his new slave, wondering how'd he like to start. Before he could decide, he felt one of Tonks soft feet poking at his manhood from under the water, before the second one joined it. Soon, Tonks was sluttily looking at Harry as she sandwiched his cock with her small feet. Harry groaned as she pumped him up and down, knowing this would be one exotic girl. After a bit of foot play, he grabbed Tonks leg and pulled her on top of him, making her straddle him with his cock inches away from her pussy. Tonks looked at him in devotion, ready for his next move. "Kiss me Tonks," Harry ordered, and Tonks quickly took her new master into a liplock, lovingly making out with him. Harry took this time to squeeze and massage the girls creamy boobs, pinching and twisting her nipples, making the girl moan into their kiss. Harry pulled away making Tonks mewl in disappointment, until he took her by the hips and dropped her down on his cock, bottoming out in her pussy. Tonks wasn't a virgin, so the scream that followed was one of pure ecstasy and pleasure, as Tonks started to bounce up and down his cock. Harry was infatuated with her beautiful bouncing breasts, as he started to lick and kiss all over them while thrusting deep into the girls vagin.

Tonks kept bouncing on his cock, having already cummed twice and about to cum a third time, she quickened her pace until with a loud moan she orgasmed again. Slumping against her master, she rested her head on his shoulder, as Harry kept thrusting into her tired pussy. Harry quickly cummed inside her, making her remember she wasn't on protection, but she didn't care. If she got pregnant with her master and lords child she would be happier than ever.

"Let's get up Tonks, I want you on the floor with your ass up high" Harry ordered. Tonks, though tired, did as her master asked and got off his cock and laid on the hard tiled floor doggy style. She stuck her sexy ass out, awaiting what he'd do.

Harry saw his new slave before him, ass up face down. He quickly moved into his position, grabbing her round ass cheeks and squeezing them, before spreading them, leaving her cute clean asshole presented to him. Harry moved his cock right to her back entrance, before slowly penetrating her with his head. Tonks moaned out, knowing it's be a tight fit already, when suddenly Harry thrust his entire length into her ass, causing her to scream in total pain and submission. Harry was an animal, leaning forward to press his chest into her back, taking her boobs into his hands from behind, as he ravaged her asshole. He knew it was painful for her, but he didn't care as he moaned at her tightness. Tonks was crying now, tears running down her face as her ass was dominated. Truthfully she had cummed several more times, although still in a hell of pain. Tonks soon passed out from the rough treatment, allowing Harry to continue fucking her unconscious ass. Harry kept this up until he released again, this time filling her backdoor with his seed. Harry stood up, picked Tonks up bridal style and laid her on a side couch he had conjured. He magically cleaned her off, careful to leave his semen inside her two holes.

Harry smiled, content with the day.

Next chapter will be between Daphne and Harry
