Your ocean science professor, Professor Arlert, always drove you crazy. There was just something about him that had you clenching your thighs. He was so proper, so quiet, and so unassuming, god you would do anything to take a bite out of him. You watched as his slender fingers traced across his keyboard, wrapping up his lecture with his standard dismissal, his blue eyes meeting your own as you sat to the left side of the lecture hall. Armin's face flushed red as he darted his eyes back down to his computer upon meeting your gaze, and you fought back a smile at the way he seemed to try to disappear into his blue sweater.

The lecture hall cleared out, scores of students leaving the room to get to their next class or simply go back home, but you lingered behind, only starting to pack up your things when the room had become slightly empty. You took your time placing your things away, the air between you and Armin growing thicker as time passed. Making your way down the lecture hall steps, you approached the lectern, Armin attempting to avoid looking at you until you cleared your throat.
Professor?" You spoke, looking up at him and stepping a little closer than you needed to be.

His face turned a soft pink as he turned his head down to look at you. "Yes, y/n?" You could hear the slight shake in his voice as you smirked up at him, taking another step closer.

God, you could do this all day just to drink in the way he reacted to you. It was precious, and the thought of what he would look like under you had arousal building in your core.

"Do you think that if- " Your sentence was interrupted, Armin jumping back from you as the next lecturer entered the room.

"Ah, Professor Arlert, my apologies! I thought your class would have cleared out by now." They spoke, their attitude upbeat.
"Professor Hange, I was just about to leave. y/n just had a question for me." He hesitated, his voice catching. "What was it that you needed?" You could see the remnants of a blush on his cheeks as he made eye contact with you. It was cute how he was trying to keep his composure, cute how he was pretending that your proximity to him didn't have him hard in his pants.

"Ah, nothing. I'll come back for your office hours." You chuckled, waving your hand. "Make sure you save me a spot okay? I've got a lot to ask." Your gaze lingered on him for a second before you turned to Professor Hange. "Nice to meet you."

Armin knew he shouldn't be looking at you like that. He knew that as a professor, he had to be professional, you were a student after all, just trying to get your education. Still, he found himself antsy at the idea of spending time alone with you, even if it simply was to go over course material. He'd even gone so far as to tell other students that his appointments were booked for the day, just in case you wanted to spend more time in this cramped meeting room.

However, his worst transgression in his mind was the way he'd groomed for you. The way he'd trimmed himself and showered before his office hours began because there was some part of him that hoped your real reason for coming was far more sinful. What he didn't realize was just how correct he was.

"Professor?" You rapped gently three times on the ajar door to his office, pushing the door open slightly to peek in.

"y/n, come in." His gaze found yours, motioning to the array of chairs in front of him.

You smiled sweetly at him, walking over to the chair beside him and taking a seat. His eyes widened at your choice, breath hitching as you scooched it closer to him. "How are you today?" you asked, leaning your cheek on your hand.

"I'm good, y/n. And you?" He was being formal, his back straight as he pretended to occupy himself with organizing his papers, pretending he couldn't see the way your eyes hungrily scanned over his figure.
