This is Magic: Ereri Harry Potter AU! Fanfiction

Chapter 17: Fifth Year

Seriously, fuck Eren.

The past two years had been exceptionally kind to that brunet bastard, who was now approaching a height of 5"7. Levi was seething every time their height difference was pointed out. Seeing as he only stood at 5"2, the lovers' contrasting height was pretty noticeable.

Although the boys had decided not to publicly announce their relationship after that one night during Year 3, it was overwhelmingly obvious to everyone that they were together. It's pretty hard to miss it when the two were constantly holding hands and blushing. Armin and Mikasa were the first to pick up on it, and though Armin showed full support, Mikasa had serious doubts. Even now, she still checks with Eren to make sure he's not suffering in any way. Levi found it annoying, but he also knew that she was just being protective.

But, let's go back to that damned height difference, because it was currently making Levi feel a special level of anger.

Eren's tongue laved at Levi's pale neck, and his mouth occasionally stopped to suck the tender skin and leave bites that wouldn't fade for days. Levi was torn between kneeing his boyfriend in the stomach or moaning in pleasure. The moaning won out once Eren trailed his hand down from Levi's back, sliding over his taut stomach and cupping him through his black slacks.

Eren was totally dominant in this position. He was towering over Levi, pressing him against the wall and pinning his hands above his head. In all honesty, Levi had the strength to rip his hands out of the teal-eyed boy's grip, but it was kind of hard to focus when said boy was rubbing at his dick like a fucking genie's lamp.

"A-ah, you little shit—" Levi panted as Eren's mouth trailed lower to capture a pert nipple in his mouth. "Fuck you and y-your goddamn height—ngh..." He could feel Eren's lips twisting into a smile as he continued to swirl his tongue around Levi's left nipple. Shivers ran up and down the raven's spine as his lover blew cold air on his chest.

"You know you love it," Eren teased, shifting his burning gaze to Levi's own eyes. His dark eyes were swirling with mischief and lust, and they kept eye contact as Eren lowered to his knees. Levi let his hands fall and grasp at Eren's robes on his shoulders lightly, his breath hitching in anticipation.

All of a sudden, a loud voice rang out just outside the empty classroom's door.

The boys fumbled to fix their disheveled clothes and hair as the door swung open to reveal Professor Hanji, her wild brown hair flying around as she waltzed in. "Hello boys!" she waved cheerily, thankfully not questioning why they were alone in an abandoned room together. She hummed a small little tune as she kept walking towards the front desk and reached into one of the drawers. "Forgot some of my research papers in here. Ha! Imagine that! It's kind of embarrassing, actually. Well, don't mind me! Carry on," she smiled, waving the papers around, and then left the room just as quickly as she arrived.

The teens watched her leave wordlessly. "Fuck, there goes the mood," Eren muttered, slumping down with disappointment. Levi took the opportunity to kick the brunet's shin, reveling in the loud yelp that his boyfriend let out.

"Next time, I'm gonna power bottom so hard that you'll beg for my ass every day," Levi called over his shoulder, smirking as he walked out of the room. From the floor where he had fallen, Eren smiled.

"That sounds like a challenge!!"

Eren's head was dizzy with excitement as the smell of leather and wood overwhelmed him. He stood just inside the Gryffindor quidditch tent along with Levi and the rest of the team. It was the day of the championship match, Gryffindor vs. Slytherin. As usual, Eren was vibrating with excitement, Levi was nonchalantly inspecting his nails, Reiner and Mikasa were discussing tactics, Jean was scowling at Eren's stupid face, Annie was silent, and Sasha was frantically looking through her bag for any and all edible products.
