Quite hard issues.

This is my first futa story ever written, it's kinda short but tell me what you think :D

Naari looked confusedly at the teacher’s misleading drawing board from where she sat, she looked to her left where her best friend Noki was sitting, seeming rather familiar with all the complicated mathematic formulas spread across it.

“Damn it”

Naari cursed to herself quietly,

“Why do I always have to stay up way too long past my bedtime than I should before school?”

She was having a real hard time concentrating on what the teacher was saying and found that fact real annoying, since clever Noki seemed to have no problems with understanding it at all.

Suddenly a thud slammed up into the underside of her desk, a low “bump!” was heard under her desk, and Naari let out a low groan:

“Ghh!”

It seemed that no one had noticed her; she concluded that she did not draw attention to herself in relief.

She bit her lip nervously, as she could feel her overwhelmingly aching erection stirred under her desk, lifting her short skirt that she was wearing. A drop of sweat slowly rolled down her forehead, as her eyes widened in panic.

She hated herself for watching hentai, ‘cause that had been what she had been doing most of the night and what she saw never got out of her head. Instead of listening to the teacher she had thought of all the hot stuff she had found on the web and masturbated to the night before.

She glanced at the clock, there was only ten minutes left of the lesson! If she rose with this huge thing poking up, everyone would see. And since Noki was the only one who knew she was a girl with male genitals, she was terribly afraid of that secret being revealed to all her fellow classmates. She didn’t want to, but it was necessary: She leaned discreetly over to Noki’s side, stuttering, anyone could tell she was excited, and whispered silently in her ear, for only her to hear:

“I-I’m all hard, it stands straight up Noki. Please make it go away before l-lesson is over…”

Noki eyed her uncertainly for a moment, but when she saw Naari’s eager, helpless face expression it just made her feel mean for not helping her friend out.

As Noki sat on the left of Naari she could easily move her right hand unnoticed in under her desk and in between her legs.

Naari whimpered silently for herself as Noki clenched her soft palm around her hard bulge in her panty, underneath her skirt.

“ Nhhh…!”

Knowing she would not be able to hold a concentrated face expression without making a fool out of herself while being stroked underneath, she pretended to be writing notes on her paper.
