Class with Progressors Ruby and Onyx could be simultaneously stimulating and excruciating. Stimulating because, well, they were two incredibly hot women with big chests who both seemed to enjoy leaning into their magic side with their dress sense. Excruciating because one of the subjects they taught was History, which was hard to make interesting even on a good day. So during a double period like this, during a bone-dry lecture that seemed to dare you to waste any attention on it, one was left with only the presenters for distraction.

That went double in a large lecture hall like this, when the pair of them were presenting material for a test later. Material Siren had already consigned herself to re-reading later. Or lying her way through. History wasn't a grade she put a lot of faith in. And she wasn't alone in her distraction either. Even though this was an important lecture and sex wasn't actually allowed, with so many students so far away, it was impossible for the pair to keep an eye on everyone, so there was one obvious way to pass the time. Little Mermaid had spotted a couple people in front of her jacking off already, sneaking their cocks out for a few tugs or girls with their hands in their panties.

She had the same idea, but she could do so much better than her hand. In fact she had her cock snug in a bubble already. Not shaped like anyone or anything this time. Just a discreet pink sphere, just big enough to make a good toy. Her right hand still holding her pen as she pretended to take notes, her left holding the bubble and discreetly bouncing and squeezing it, working her dick under the desk as she watch the two pairs of massive funbags parading at the front of the class, completely oblivious to what their owners were trying to teach.
