Being bolder, but don't go crazy.

For a moment Mason simply admired his handy work. While on their own his teacher's recently expanded breasts were nothing extraordinary, he couldn't take his eyes off them. Part of it was just how good they looked on her. They were wonderfully full and round and looked all the bigger on her svelte body. Part of it was an attempt to make it seem like he was still listening. Nice as she was she would still probably confiscate his phone, something he now wanted to avoid at all costs. And part of it was the shock that this app was for real. It didn't cause the sky to fall and did exactly what it said it would. Ms. Bailey's bust had expanded and neither she nor any of his classmates seemed to have noticed.

It was a rush. It was such a simple change, but it whetted his appetite. The new trait was from the lowest level box and was only level one. Who knew what else this app could do for him? He certainly didn't. But he was eager to try and find out.

While Ms. Bailey tried to explain the Battle of Blood River to her class, Mason contemplated his next move. Knowing that, even though they were random, the traits he unlocked weren't automatically activated and that they could be turned off later was a game-changer.

At least it was if he was right and traits could be switched back off. A quick glance showed that indeed the blonde woman's new Apples and Oranges trait did have an option to turn it back off. That was good. That gave him the confidence to try something else with his teacher.

He still wasn't sure how or even if he wanted to mess with Ms. Bailey's kinks. While she was undoubtedly hot, there were two big problems. The first was that the two weren't in a relationship. Her kinks really didn't mean much to him if they weren't sleeping together. And the second was that even if somehow did get under her skirt that could cause serious problems. If Ms. Bailey got caught sleeping with a student, she would definitely be fired and possibly arrested. That was definitely not something he wanted for his favorite teacher.

In theory, the app may be able to help him with one or both of those problems at some point. But at least for now, the kinks panel seemed like a waste of time. Mason also decided to not check on the relationships menu just yet. Relationships were complicated and he needed to split his attention between the app and pretending to listen to Ms. Bailey's lecture.

But directly below the body menu was an intriguing option. Behavior. Before he was a little worried about this option. It wouldn't be too hard to change how Ms. Bailey acted for the worse. She could be made meaner or coarser or just worse at her job. And of course, it also could also get her in trouble if the app made her do something really crazy.

But in light of how the app seemed to actually work, it was the most interesting option. If the app gave him a really crazy option he could just not turn the trait on. Or at least wait until the time was right. So now he clicked his way to the behavior menu. It was almost identical to the body menu, but it was still blank.

Mason tapped the icon to buy traits and found himself looking at the same three presents. He stopped and thought for a second. He only had five hundred and three silver left to spend on his teacher. And at the moment he had no clue how to gain more silver. He still couldn't afford a large present. So he was left with a conundrum. Part of him wanted to try a medium present, but that would only leave him with three coins.

His inner gamer told him to conserve his resources. What if he needed them later? But he tamped that part of him down. This wasn't a game. So he nutted up and tapped the medium present. The same animation played and another scroll unfurled.

Congratulations! You unlocked a new Trait!

Oh, You Tease: Rank 1! She just can't help but flaunt the goods. Whether she knows it or not she'll show off when you're around. (Note: If you set other's awareness to on she'll tease them too!)

That sure was something. If Mason wasn't in class he may have jumped for joy or laughed maniacally. But he couldn't do either without causing a scene. He still couldn't stop the big stupid grin from spreading on his face. If this kept up his cheeks were going to be sore for the rest of his life. But he decided that was a price he was willing to pay and activated Ms. Bailey's new trait.

He contemplated for a moment about the awareness toggles. But it was only a moment. He left her's off. He'd test the awareness toggles on someone else. Someone he liked less and wouldn't mind messing with. And as for everyone else he decided to keep them in the dark too. He still didn't want his favorite teacher to get in trouble. It definitely wasn't because he was just feeling selfish and wanted the show all to himself. No, sir. Perish the thought.

At first, he didn't really notice a difference. There was Ms. Bailey writing on the whiteboard. As usual, she was condensing her lecture up to that point into the important bullet points. Her right hand started as high as she could reach, filling the void with her clean, legible script. Her left hand held as many markers as it could, letting her easily change colors whenever she changed the topic or needed to highlight something important. It was so normal, in fact, that Mason found himself actually paying attention to what she was saying.

But that didn't last long.

Things changed when she reached about halfway down the board. Any other day, when she got too low, the blonde would just start a new column. Even fifteen minutes ago that's probably what she would have done. But she kept going, writing lower and lower. Most women doing this wound probably just crouch, keeping their legs together if they were wearing a skirt like she was.

That is not what Ms. Bailey did. No. She slowly arched her back and shuffled her feet backward to help facilitate her bending at the waist. And the lower she had to write, the further she bent until she reached the very bottom of the board. Then there she was, her legs spread, her skirt riding up ever so slightly, her body bent almost a perfect ninety degrees, and her butt almost level with her blonde locks. There was no other way to describe it, she was sticking her ass out at her class.

And it wasn't just at any ass. It was the ass of Zoey Bailey, his favorite and hottest teacher. The ass he had ogled for four years. For his entire tenure, he had tried to get the best look he could at it through the modest skirts and slacks she unfortunately always wore. Now here it was, straining against its fabric confines. Almost every detail of its round, bubbly heart shape was on display. As he took it in, impulses and fantasies flashed through his mind. He wanted to reach out and get two big handfuls of those lovely cheeks. Or maybe sink his teeth into that delightful peach. Although he could also give it a few firm smacks, just to watch it jiggle and shake.

Another part of his mind also reminded him of an important detail. She technically wasn't sticking her ass out at her class. She was sticking it out at him. Or maybe it was for him. After all the app made it clear that as long as others weren't aware she wasn't teasing them. Just him, it was all for him. It made him wonder if he had made the right decision in leaving her awareness off. Mason had been operating on the assumption that Ms. Bailey would be puppeted around by the app, her body **** to move against her wishes. And while that may have been fun to inflict on some women (a few of his other teachers came to mind,) it wasn't what he wanted for her. But what if that wasn't how it worked? What if it made the beautiful, blonde, belle actually want to tease him?

His mind wanted to try and figure this out. Or figure out a way to test it. But he could hardly think. That may have had something to do with most of the blood in his body had traveled far lower than his brain. He had never been harder in his life. Erections were nothing new to the nerd. In fact, it usually didn't take much to get his dick ready for action. Now though he was pitching quite the tent in his jeans. There was even a growing wet spot in his boxers where glossy precum was leaking from his tip. He could only hope no one noticed.

Unfortunately, he was granted a reprieve. Of sorts. Ms. Bailey did eventually straighten up and turn around. She also cocked her hips to the side, her right hand resting on her thigh. Meanwhile, her left arm crossed across her chest just under her breasts, pushing them upwards and making them all the more noticeable through her sweater. She was practically offering up her tits on a platter for him. And Mason was all too eager to let his eyes devour her.

And that was the next half hour of his world history class. His bespectacled, blue eyes stared in amazement as his lovely teacher both taught her class and relentlessly teased him. Well, he assumed she was still teaching them. Honestly, everything she said simply went in one ear and out the other. He could only hope it wasn't anything really important.

And he felt no guilt about not listening to her. None whatsoever, given his current situation. Despite his teenage hormones making him more or less constantly horny, he had never actually creamed his pants before. And at that moment he felt very grateful to still be able to say that honestly. But given how achingly needy his cock was at the moment, it probably wouldn't take more than a stroke or two before he would be cumming his brains out.

And all because his teacher was posing like she was on the set of a softcore, pornographic photo shoot.

Part of him wondered why this turned him on so much. Logically, this shouldn't be that amazing to see. Mason had been to the beach and seen women in bikinis. He had the internet and had seen women in lingerie or nothing at all. And yet Ms. Bailey in a comfy sweater and woolen skirt outclassed them all.

Maybe it was because of how she was dressed. It could have been something about the juxtaposition of her modest clothes with utterly licentious posing. Something in the way her voice kept calmly teaching African history while her body screamed "Fuck Me!" Or maybe it was something about how out of character this was. The blonde had always been relatively reserved. She never dressed in any way short of professional, never talked about her own romantic life, or acknowledged the raging hormones of her students. And yet now, here was her sexuality in full bloom. Or maybe it was seeing four years' worth of his fantasies actually coming to life. This absolute goddess had been a fixture in his spank bank for quite a while. Although his dreams usually didn't stop here. But the app would almost certainly help with that. And maybe that was it. Maybe this was all just a power trip he was on. It could just be that the thought of turning his ordinary life into one of boundless hedonistic delights was already getting to him.

Whatever the case, it had to be said: This was far and away the best class he had ever been in.

Unfortunately, it was ending soon. And it left him with a question.
