Yes, but carefully

Anna can feel her heart pounding in her ears, which makes it hard to even hear Dr. Wood as she begins her lecture. She waits until a few minutes into the lecture and everyone seems focused on taking notes before she lets her hand start drifting down towards her most intimate place. Anna rubs the top of her thighs, moving closer to her folds, and has to swallow a gasp as she realizes just how soaked the inside of her thighs are. Anna didn't realize that even her orgasm in the bathroom earlier didn't actually lower her desire, but led her to an even greater high now.

Anna had to bite her lip to stop herself from moaning as her fingers slid between the drenched folds of her sex. Even the slightest touch was sending jolts of electricity up to her head and down to her toes, which curled instinctively. Anna moved slow and methodically, partially to savor the feeling, and partially to make as little squelching sounds as possible as she moved fingers through her folds. Anna bit down on her lip harder as she brushed against her clit, sending even greater jolts of pleasure through her body as she fought to hold back the moan she desperately wanted to release.

Over the next few minutes, Anna got more daring, moving her fingers against her clit more often, and plunging a couple fingers inside her vagina as consistently as she could. She slid down in her seat a little bit to get a better angle, plunging her fingers deeper inside herself. As she got closer to her climax, she closed her eyes and plunged her fingers as deep as she could, bringing her thumb to her clit at the same time. This drove her over the edge, as she brought her free hand up to bite on, trying desperately with what little conscious effort she had left to stop from moaning out loud in pleasure.

As she settles down, Anna scoots back up in her chair, opening her eyes to see if she managed to get away with it.
