This is Magic: Ereri Harry Potter AU! Fanfiction

Chapter 16: Third Year

During summer, things changed.

Eren was really confused, in all honesty. He had been with Levi for a year and a half already. They had been inseparable since they'd shared the same dorm in their 1st year. So why, out of all times, was Eren feeling so weird? Why now?

The question kept circling around in Eren's head as he watched Levi emerge from his pool. When the brunet glimpsed the beads of water rolling off of Levi's smooth, pale skin, he started squirming uncomfortably. There was a burning feeling in the bottom of his belly, and his heart was hammering. If he were to look into a mirror at that moment, Eren was sure that his face would be as red as the hair on Isabel's head.

"Why aren't you swimming again?" Levi called out to Eren as he approached him leisurely. Eren gulped and glanced back down at his book.

"I'm not a fan of water," Eren mumbled, slouching and trying to calm himself down, to no avail. His body was going haywire as Levi approached him. The raven got so close that Eren could make out the details; Levi and he were 13 now, and they had both started to grow. Eren was shooting up, now at around 5'4", while Levi was filling out rather nicely. And boy, could Eren tell when he looked at Levi's amazing body that his friend had been staying healthy.

Levi shrugged, grabbed his water bottle, and headed back towards the pool. Eren was disappointed for the wonderful view to be gone so quickly.

Year 3 was an interesting one, to say the least.

The feelings that Eren had acquired over the summer didn't go away. In fact, they seemed to grow as time passed.

A year ago, Eren would've been completely fine with the situation he was in at the moment.

A year ago, Eren would most certainly NOT be secretly ogling his roommate as he changed from his robes into more casual clothes.

A year ago, Eren didn't have these weird feelings...

The burning in his belly was back.

Eren turned away from Levi's creamy skin and developing muscles, trying to will away the odd feelings. It must not be normal. After all, nobody had talked to Eren about feeling strange around this age. Everyone else seemed to be doing just fine! So why was the brunet feeling this way? Was he a freak? Why did he have the sudden urge to....touch himself....

"I'm leaving now," Levi's voice cut through Eren's thoughts and startled him enough for the brunet to jolt.

"Oh, um, have fun," Eren said with a smile that screamed "fake". Levi watched Eren with his silver eyes for a little longer, deciding whether to comment, before leaving with a wave and nothing else.

Eren let out a huge sigh once the door closed behind Levi. The brunet flopped backwards on his bed, and lay there for a while, just thinking. He turned on his side, away from the door.

All of these urges were completely new...Why was he reacting this way? Eren blushed hard when his hand subconsciously brushed past his lower body. It wouldn't be so bad, would it? It's just instincts... Biting his lip and throwing caution to the wind, the teal-eyed boy rubbed at himself with hesitance.

"A-ah," he let out a small cry. The pleasure he felt coursing through him was unexpected, but not unwelcome. Eren let mental images of Levi shirtless flow through his mind, and his hand quickened it's pace.

He paused quickly to roll his shorts over his hips and down his legs. Then, he took the hem of his shirt and held it in his mouth. This way, Eren's voice would be muffled, and he could have more access to his body. A moan passed through his lips, which was clamped down on his shirt, as he applied feather light touches to his dick.
