She plays it cool. Yumi... doesn't.

Mason was literally watching the seconds tick by when the bell finally rang. A whole fifteen seconds late he might add. Yumi and Vina wasted no time saying hello. Mostly because the Muslim girl had to almost immediately book it to her next class. Though she still managed to fit in one bone-bruising hug before she left.

He did his best to not make the "love to watch you leave" joke. Though it did cross his mind. (Mostly because it was one of Mamita's go-to not-technically-a-Dad jokes.) But his heart wasn't really in it. Not that Vina's curvy body wasn't nice to ogle. He just would have preferred to have more time with his new girlfriend.

Maybe the app could help with that somehow?

He would have to put a pin in that though. His first girlfriend was shaking like a leaf next to him. Yumi's round face was looking up at him, looking a little green around the gills.

"What's wrong," Mason asked her. He put an arm around her shoulders which seemed to help her relax. At least enough to let her answer him.

"Nervous," Yumi muttered, her little voice barely audible over the hubbub of their fellow students. Really it was thanks to the fact that Mason was holding her close as they walked to class. Not exactly subtle, but when his oldest friend was in this sort of state he couldn't care less what rumors started.

He also could understand why she felt that way. Oddly though, Mason felt a little buoyed. Sure they were still walking into something absolutely insane. But compared to his vice-principal, his history teacher was just a lot more approachable. And while Ms. Bailey always could (and had every right to) change her mind, the most dangerous part of this tightrope walk might be behind them.

At least, he hoped so. Then again he hadn't seen her in almost a full day. Which may not have seemed like a long time. Until Mason thought about everything that had happened since he last saw her.

"Hey, you two," The blonde woman said as they walked into her classroom.

It was a positively normal scene. Ms. Bailey stood at the front of the room wiping her last class's lessons off the whiteboard. She wore a ruffly, grey blouse and a plum-colored tulip skirt over white tights. The only thing missing from her outfit was her typical sweater. But Mason spotted the cardigan draped over her chair. What also proved to not be absent was her smile. It was as bright and cordial as always. It reached all the way to her eyes which shined with friendly blue light.

It was like any other day. Ms. Bailey just seemed happy to see two of her favorite students.

"Hello," Mason said back. As he and Yumi walked back to their desks the two shared a look. The short girl gave him an astonished look, eyes as round as her circular frames. And he probably had a similar look on his stupid mug. Ms. Bailey had played it cool as a cucumber. In fact, she may have an even better poker face than Ms. Rosso.

The two sat down pulling out their books. They actually beat most of their classmates there. So they actually got to watch most of the other teens stream in. They largely looked torn between being tired at the end of the day and happy that both it and the week, were almost over. Mason wasn't really sure what he was looking for, but something told him to watch. It wasn't until he turned his head that he realized what he was feeling.

Sitting in the back was a familiar goth girl staring at him. Charlotte was leaning on one hand, and twirling a black pen with the other. And as he had noticed more and more her wide pink eyes were locked on him. So Mason offered her another wave. One that should have elicited some reaction. But as usual, she just stared him down with an eerie calmness.

When he turned back around he saw a pair of Hazel eyes locked on him instead. Yumi was a little confused, at least he guessed that was why she cocked her head. But before he could ask a question the bell rang and Ms. Bailey started her class.

The blonde's passion for the subject matter was plain as the nose on her beautiful face. They were still in the middle of the colonial era. An era that was, to put it mildly, a bummer. But as Ms. Bailey had stressed when they got to the 1600s that the bad parts of history were the ones that they really needed to take a good hard look at. She was also spectacular when it came to providing just historical distance to make things comfortable and even fun.

This was one day when the latter was going to be a little tough. They had reached the point in world history where there was going to be just a flood of relatively dry historical documents. Or as Ms. Bailey called them, valuable primary sources. And today she had a small packet of them for her students to read and discuss.

This was the first time that things derivated from the norm. Because usually, Ms. Bailey would go with the tried and true method of handing a stack of papers to the first person in each row and having them pass back the rest. But now she walked up and down the aisles handing them out one at a time while giving a primer on what they were reading.

Mason noticed it but didn't think much of it. At least until he started reading. They sat there in silence reading the first of the three documents, all of which would provide rotating views on the Dutch invasion of Brazil. But when Mason turned to page two he was snapped from 1635 all the way to the present. Because there was a note in the margins. Written in Ms. Bailey's neat handwriting.

Dinner tonight at my apartment. 7:00. I added an extra page to your pack and taped a guest parking pass to it. Dress up nice and I'll do the same. See you then.

Under that were an address and a phone number. If Mason was a betting man he would say they were hers. He looked over at his petite girlfriend but her nose was buried in the assigned reading. Not that he could really talk about the note at the moment. Well, he could if he wanted to out the whole sordid affair.

Potentially sordid affair.

The butterflies in Mason's stomach must have been throwing a rave. That would explain the wild flip-flopping he felt in his guts. Then again maybe it was because his gorgeous teacher, the subject of a small crush for the last few years, was actually going to have at least one date with him. He tried to keep his eyes on the paper, but he kept glancing up at Ms. Bailey. She seemed more beautiful than ever before.

And all of this was because of Lilith and the app. Even if he was terrified of what she would do if she ever had free reign over his life.

But thinking about Luxuria reminded him that he had set up a surprise for Yumi. He just had to wait for the right moment. It took a while for that to happen. After talking about the first document, a relatively dry, Spanish pamphlet condemning the Dutch aggression, they were back to reading. And that was when Mason acted.

When Ms. Bailey turned to write on the board again, prepping for their next discussion, Mason pulled out his phone. He unlocked it and tapped his way to Luxuria. Then, with an eager grin, he turned on her Oh, You Tease trait. It took effect even before he looked up. Her back had arched to push her bubble-butt out at him. Only this time it wasn't just for his eyes.

He looked over at Yumi who still had her head down, completely oblivious to what he had done. It was a little disappointing, but the tiny nerd was too cute to be mad at. All it meant was that he had to change tact.

"Ms. Bailey?" Mason asked, raising his hand. She turned to look at him with a helpful smile. That got Yumi's attention too. Though the look on her face was very different. Her mouth curved into a small frown and her eyebrows scrunched. It was a silent question. One he answered with a small, playful grin.

When the two looked back at their teacher she finally noticed. Her mouth fell open and her face turned cherry red.

Ms. Bailey was strutting down the aisle between them like it was a runway. Her ankles crossed with each step, helping her hips swing from side to side. She was showing off her figure for them, with the cut of her skirt emphasizing her feminine form.

Yumi snapped her mouth shut and did her best to look back down at her assignment. But try as she might her hazel eyes kept flicking up to follow her teacher's long legs with each sexy step. Except when they watched him enjoying the view instead.

"What is it, Mason?" Ms. Bailey asked. When she stopped next to him, she cocked her hips with one hand on her thigh and the other toying with her hair. Yumi by contrast was hiding behind her hair. She watched the unfolding scene through her glasses and between the long, black strands.

Which was exactly what he was going for.

"I'm just not sure who this is." Mason pointed at the three-part name in the middle of the page.

For a moment Yumi looked relieved, and Mason couldn't help but wonder what she was expecting. Of course, his petite lover wasn't out of the woods yet. And he shot her a wolfish grin to let her know that.

Ms. Bailey slowly bent over to see what Mason was pointing at. He couldn't see exactly what was happening, but that was fine. His personal experience filled in the blanks. She would lewdly arch her back and straighten her long legs. That way she could shove her luscious ass in Yumi's face. Then maybe she would give it a little shake just to twist the knife.

It was no doubt leaving Yumi flustered beyond belief. But as far as he was concerned, this was just a turnabout. Which was obviously fair play. Granted his girlfriend didn't know that one of her questions put him in the exact same position. (Save for the fact that Ms. Bailey's ass was at exactly eye level for the short teen.) But that was small potatoes.

"Ah, yes. So Moses Cohen Henriques was a Jewish pirate who worked as a privateer for The Netherlands." Though to be fair it wasn't like Mason wasn't getting an eyeful as well. Ms. Bailey had propped herself up on her elbows. She lifted her hands to gesture, meaning her forearms pulled the thin fabric of her shirt tight across her chest. It laid bare every detail of her ripe, round breasts, right down to the lace edging of her bra. But what really caught his eyes was the way it strained her buttons. It gave him a few precious slivers of pale flesh to look at.

But he couldn't think of another question to keep his teacher in her unknowingly compromising position.

"Thank Ms. Bailey," Mason said as she slithered upright. It was a short, little moment. A little too short and too little for his taste. But it was at this moment he realized he was both blushing and hard again. So maybe it was for the best.

"Of course. I'm happy to help. And if anyone else has a question don't hesitate to ask," She said, first to him then to the class as a whole. Her butt swayed hypnotically as she swaggered back to the front of the room.

But Mason tore his gaze away as soon as he could. Partly because he remembered that people could notice him staring. And partly because there was another lady that demanded his attention. He turned his gaze to Yumi and was met with a floored expression. Her jaw had dropped and her glasses were only a few centimeters from clattering onto the floor. She looked so shocked that some of the color had actually drained from her face, leaving her closer to pink than red.

That only lasted until he flashed her another toothy grin. That made her flush all over again. The killing blow though was when Mason leaned back in his chair. He had been sitting forward in his desk, Tegan often complained about him leaning over too much whenever he read something. Which helped hide the boner he had popped. But now he made sure his girlfriend got a good look at its outline in his jeans.

Yumi saw it. Her eyes didn't flick down, but Mason knew she saw it. Because all of a sudden she turned away from him, pushing up her glasses and staring resolutely down at the paper they were supposed to be reading.

For a moment he faltered. Messing with Yumi like this was… Okay, he would admit it. It was downright fun. But for just a moment Mason wondered if he had gone too far. Sure the way the petite girl squirmed in her seat made it clear she was enjoying this. At least a little

But he couldn't help but worry if he had gone too far. In fact, he felt ready to slap himself when he realized Yumi couldn't use her safe word in the middle of class.

Are you alright? Mason scribbled onto his notebook so quickly that he had to do it again. For legibility's sake. She looked over as soon as he angled his notebook at her.

Yes. Yumi wrote back.

Do you want me to stop? He asked her.

No. That was what she wrote, but Mason wasn't convinced. Sure he didn't think she would lie to him about something that important. He just wasn't sure that she wouldn't get swept along by her Subby For Hubby trait.

Tap three times if you change your mind. That made the girl look at him with hazel eyes filled to the brim with love. Yumi gave him a quick thumbs up before she went back to reading.

Though every now and then she glanced up at whatever erotic pose Ms. Bailey had adopted. Mason might have given her some shit about that. But he didn't want to be a hypocrite.

After that, the class was almost normal. Ms. Bailey led them through a discussion on the next two sources. Mason did his best to participate in the discussions and act like his teacher wasn't posing like a Playmate. Yumi didn't. But even that was pretty normal. The shy girl usually would just sit and listen until she had a question. So she silently absorbed what was happening even if she wasn't doing a very good job of hiding what she was staring at.

Though to be fair, she probably didn't have as much experience in subtly leching over her teachers.

Yumi's eyes would occasionally also glance around at her classmates. It was another moment Mason recognized even if he had never seen it from the outside before. After all, he had been in utter disbelief that no one else noticed anything as well. Though he imagined, in fact he was sure, that the petite girl's awestruck expression was a lot cuter than his.

Once they were done with their reading, Ms. Bailey set out in a more traditional lecture. She carefully laid out the problems with primary sources. The implicit biases and what (as well as who) was often left out. After that, all that was left was to walk the class through either verifying or refuting all the things their reading assignment said.

Treating it all like a big mystery made things a lot more interesting. But Mason's mind couldn't fight the urge to wander. It wasn't a knock on Ms. Bailey or her teaching. It's just that Lilith had more experience when it came to garnering male attention.

So when Ms. Bailey turned to write a few more notes on the board, he tore his eyes away from the way her skirt hugged her backside and looked down at his phone again. When they had walked into class earlier he only had eighty-eight silver left for his favorite teacher. Which, frankly, was nothing in the grand scheme of things. But he suspected that had changed.

Zoey Bailey scheduled a date with you! Hope you're ready for some private tutoring! You earned 150 silver for Zoey Bailey!

Zoey Bailey shoved her ass in Yumi Kamiya's face! And you stared at her tits! Hopefully, this is foreshadowing! You earned 100 silver for Zoey Bailey and Yumi Kamiya!

You and Yumi Kamiya enjoyed the show Zoey Bailey was putting on during class! You earned 50 silver for Zoey Bailey and Yumi Kamiya!

388 silver on the other hand offered some possibilities. Well, two possibilities. He could buy a new trait or upgrade an old one. On the one hand, he had yet to get a bad trait out of Lust Box. And Ms. Bailey in particular had done well with the small ones. But a lot of traits so far didn't have an immediate effect. Which was fine, but at the moment he wanted Yumi to be able to enjoy the shenanigans.

So that meant upgrading a trait. His first thought was obviously Oh, You Tease. Not just because he had already gotten a lot of mileage out of it, but because it could also help him get more silver for later. Then Mason deflated when he remembered that particular trait came out of a medium box. So he had nowhere near enough silver to upgrade it. And, unless something crazy happened, he wasn't going to by the end of class.

His blue eyes drifted over to his girlfriend. Despite the pink in her cheeks, Yumi was once again totally focused on the lecture. In fact, her studious note-taking took up enough of her concentration that she hadn't even noticed him messing with his phone again.

For a moment Mason was reminded of how much he loved her. Maybe it was the way her eyebrows furrowed when she concentrated. Or maybe it was the way she color-coded her notes. Or the way she occasionally had to blow a few stray strands of hair out of her face.

Or maybe it just was the lifelong relationship that had slowly but surely built up a bond of mutual respect and affection.

But whatever the reason it made Mason drift back to their conversation last night. And one particular moment Yumi really enjoyed.

"Eep!" The tiny girl squeaked loudly enough for everyone to hear. More than one of their classmates jumped.

"Yumi? Is everything alright?" Ms. Bailey asked, with a concerned look on her face. But Yumi didn't answer her immediately. She was too busy staring at her teacher's chest. The older woman's shirt was now stretched tight across her bustline. Or more specifically her new, larger breasts. If Mason had to guess he would say they were now big, full Ds.

"I-I-I'm alright, M-Ms. Bailey," Yumi automatically stuttered out her answer. But she quickly changed her tune. "Um, actually could I use the restroom?"

"Of course. Just don't dawdle," Ms. Bailey answered immediately. She had never answered "no" when asked that question. At least not in Mason's experience.

So when Yumi scurried over to the door, grabbed the hall pass, and made a hasty retreat, no one really paid much mind. Sure a few other students exchanged confused looks. But most people just wrote it off as a weird thing from the quiet, nerdy girl and went back to listening to (or pretending to listen to) their teacher's lecture. Though part of that was also the fact that Ms. Bailey hardly broke her metaphorical stride. A signature good teacher move to sweep away a potentially embarrassing moment.

When the door shut Mason looked back down at Luxuria.

Apples To Oranges: Rank 2! You can now increase Zoey's boob size by one cup! Hope you can still pay attention in class! Rank 2 Bonus: Better change that to two cups! I think they now officially qualify as "Bazongas!"

But the trait description wasn't the only thing that had been updated.

Yumi Kamiya watched you enlarge Zoey Bailey's tits! Now that's what I call a show! You earned 50 silver for Yumi Kamiya!

Well, that was a nice bonus. Mason was a little disappointed that hadn't gained silver for Ms. Bailey too. But he supposed it would be a little broken to gain silver for spending silver. He supposed that even Lilith had to care about balance a bit.

That was when his phone silently received a pair of messages.

Lilith: Hey I care a lot about user experience! Just not as much as user experiences! If you catch my drift! ;)

That just merited a roll of the eyes. Even if he knew that would just make his demonic patron giggle harder. The second one was more consequential.

Yumi: Sorry! I just needed a break. Please don't be mad…

Mason: Why would I be mad? I was intentionally messing with you. And it's not like I forbade you from leaving or anything.

Yumi: … Shouldn't I have asked for your permission?

Mason had no idea how she would have been expected to do that. They were in the middle of class and all eyes were on her. It just didn't seem reasonable.

Unless that was the point.

Mason: If I didn't know any better, I'd say you were fishing for a punishment.

For a few moments, he watched the dots appear and disappear. Apparently, his submissive girlfriend was having a hard time figuring out how to put her thoughts into words. Or, knowing Yumi, she was just too embarrassed to write it out.

Mason: We'll talk after class.

Yumi: Ok.

While texting Mason also couldn't help but notice the clock in the top right corner. There actually wasn't much time left in class. So, with a heavy sigh, he chose to do the responsible thing. Once again he disabled the trait to give himself, and now Yumi, the chance to cool down.

Ms. Bailey's posture went from lewd to professional with the flick of a switch. And it wasn't long before Yumi skulked back into class. She looked extremely embarrassed at first but seemed to relax a little when she realized her teacher was back to normal. Well, other than her still expanded breasts.

But even with that, things were once again normal. After another fifteen minutes or so the bell rang, ending another wild day of school.

Ms. Bailey bid her students farewell as they shuffled out. Mason knew the point of her note was to eliminate the need for him to stay late for the umpteenth day in a row. But he and Yumi were still some of the last out.

"Have a good afternoon you two," Ms. Bailey said as they walked past her desk.

"See you later Ms. Bailey," Mason said with a quick nod. The two locked eyes. An unspoken acknowledgment that they would see each other again in a matter of hours.
