The Coffee Cup Prank

Shota/Els

The games the teachers play on one another are always so silly, Elly thought as she crept into 1-A's homeroom. It was the same in America as Japan; the staff kept each other on their toes by friendly (and sometimes not so friendly) rivalries. This time she had been approached by class 1-B to steal Aizawa's coffee cup. 

Ridiculous.

But she would be seen as a spoilsport by not participating, and really, the chance to tweak the cranky man was too tempting. They had been flirting for so long that the faculty was starting to believe they were dating. She truly would welcome any attempt made on his part, but so far all he had done was tease her. She slipped in behind the black suited hero as he came back from lunch. It was common knowledge that he napped every chance he got and she was thinking this was her best opportunity.

But this time Eraserhead didn't nap.

He sat down in his chair and looked casually around, sighing when he confirmed his solitude. He furtively reached below his belt, unfastening a pocket or zipper or something. She nearly choked, her eyes bulging and tail fluffing out in all directions when she saw him slip his stiff penis out. Elly gasped and found that she couldn't look away. She stayed where she was, not even willing to place her mask over her mouth for fear of making a sound that would alert him. 

He carefully ran a hand along the pale, trembling member, his expression somewhat dreamy. After only a few strokes, however, he stopped. Aizawa paused, frowned, and then slowly licked his palm before returning it to grip the firm length below. He pulled his hand up, sliding the skin underneath with his saliva causing a faint squelching sound. "Yes," he moaned. She watched, fascinated and just a little afraid. What if he turned and used his quirk on this side of the room? She hadn't spoken for fear of embarrassing him, but it would be far more awkward if she was spotted now. And as she grew more uncomfortable, he suddenly did something that temporarily eradicated all thought from her mind.

"Ches," he panted hoarsely, groaning her name, hair swinging forward to cover his face. "Take me..!" His breathing came and went in hoarse, ragged gasps as his hand squeezed and pulled faster and faster. She held her own breath, sensing from his jerky movements that he was close. Aizawa stiffened and his hair flew up in that strange, unseen breeze that happened when he used his quirk. His eyes were glazed with pleasure but still dark, not red. Her heart beat crazily in her chest, thumping so hard she pressed a hand to it. 

It happened when he had an orgasm.

She didn't even see him covering himself with a handful of tissues he had gotten ready ahead of time. She just concentrated on breathing. She was weak in the knees and knew she couldn't stand much longer. His performance had destroyed her on both a physical and emotional level. There was an unbearable plumpness between her legs and her heart felt like it was about to burst.

She wanted him more than ever. 

He carefully wadded the tissue up and tossed it in the wastebasket next to his desk. After that he sighed gustily, rolled some distance away in his chair and threw his head back. A buzzing snore filled the room. 

Elly snuck up and carefully took the cup, shaking as she did. This close she could smell him, and she wanted more than anything to kiss those dry lips. Pushing the thought from her mind she crept back out, thanking her lucky stars she hadn't been caught. The door clicked shut behind her and Aizawa raised his head, one eye opening slyly. A slow, creepy grin split his lips as he sat back up and opened his desk drawer. Inside sat his actual mug. 

The one she had was Vlad's. He had stolen it previously when he heard of the prank. Aizawa snickered softly and set it down. That's what she got for trying to sneak into his classroom.
