"Control"

Of course everyone was confused, as that's the only thing they've been doing the entire time he was busy working on his special project that he refused to tell any of them about.

"I get that you're confused, but powers are divided into two types of control. One is the control you've all been doing, but today I want to tell you all about CONTROL."

Everyone looked even more confused at what Billy was trying to say, as it just seemed like he was saying the exact same thing twice, just one a bit more serious, probably because of how tired he seemed to be.

"What you've all been training in, I'm guessing, is all the different ways you could possibly think about how your powers could be used, right?" Billy asked as everyone nodded their heads, as what else could they have been doing this entire time?

"Now..." Billy takes a deep breath as he straightens himself up a bit and takes a deep breath. "How many times can you use your powers for a day? How many seconds does it take? Is it possible to quick-shift between doing one thing and another? How about the limit for how long you can continuously use the power without feeling drained?"

Billy said as fast as he possibly could, confusing everyone, which just made him smile as he remembered when he had to deal with the exact same thing when he first heard it from his trainer, who was way too used to this to care if they memorized what he said or not.

After repeating himself a couple of times, everyone finally memorized and even wrote down what Billy said. They all realized they had no idea about anything he asked, as that's something they never even thought would be necessary.

"Don't worry about not knowing about this, as it's something optional that's only told if you plan on actively using your powers for your future jobs. And as I want to be a professional hero, I must know my limits better than anyone else, and so should all of you, as it's just something I think is good to know."

Billy walks away for a bit and then comes back with three booklets with their own color-coded pens, with Faith being green for her former school's cheerleader uniform, Deana being normal black as she wanted to play soccer, and Tamara getting pink as she was a seductress and everyone knew it.

"For the entire week I don't want you to ever use your powers without thinking about how long they last, what their limits might be, and just how many times you can do it in a row."

Having nothing left to say, Billy left the group as he headed towards the kitchen, where his sisters had been hiding, as they didn't want to disturb Billy's class... or at least that's what they told the group as they entered the house.

When in reality what they really wanted was to tease and mess with Billy, as anytime Billy looked up, they were either making out with one another, pressing their tits together by hugging with their shirts off, showing off their bodies by doing a sexy little dance with their clothes on, or just straight up flashing him by revealing their tits, ass, or pussy.

Having had enough of this, Billy got up and walked over to his sisters as he forcibly kissed Danni while making sure to grab her right breast as he cupped Stephanie's left cheek and **** her close to him as he parted ways from an eager Danni and went over to Stephanie.

After two minutes of kissing both of them, Billy stops kissing both of them as he whispers into their ears. "Thanks to all your teasing these past three weeks I'm harder than ever, so do be sure to keep it up."

Squeezing the girls, causing them to moan a bit, Billy let the two go as he walked back over to his class, who were entirely silent as well as bright red for some reason. "Well, now that you all know what to do, I hope you all have a nice week, and I'll see you next time."

Calmly standing up, Billy walked towards his room and closed the door as he began panting, as he so wished that the girls didn't hear what he was about to do to his sisters or realize that the wrinkle in his pants wasn't really a wrinkle but more of an outline.

Using his enhanced senses to their max, Billy saw right through his door and watched as his students shrugged and began walking out of the house, as Stephanie and Danni were very red and seemed to be very impatient for the girls to leave.

Once they finally left, Danni locked the door and quickly made a mad dash towards Billy's room, trying to beat Stephanie, but the two girls for some reason first made a stop inside Stephanie's room, and that was when Billy stopped watching as he began eagerly waiting for them.

With a gentle knock on his door, Stephanie and Danni both entered Billy's room wearing nothing but very see-through lingerie, which was nothing more than a little dress where the bra had a cut revealing their nipples.

"My, my. Eager, aren't you girls?" Billy joked with a chuckle as the girls were basically panting as they were constantly rubbing their legs together.

The first one to pounce was, of course, Stephanie, as she couldn't hold back anymore, and thankfully Billy got undressed, as from the crazed look in their eyes, he was certain they might have torn his clothes off!

"Oh, you can't believe how much we need this as well, Big Bro." Stephanie said, and Billy could swear she practically moaned the last bit. Which almost distracted him from the fact that Stephanie just called him "big bro" in such a gentle way.

And if not for the fact he was seconds away from fucking her, this would have brought a tear to his eye, but as it was, Billy was too distracted to feel anything other than the desire for Stephanie to quit teasing him and finally drop!

Danni, meanwhile, walked over to the two with a sway in her steps as she straddled Billy's face, and he happily enjoyed the meal the two brought him.

Grabbing Danni's legs and holding them in place, Billy activated his enhanced body, enhanced senses, and speed. Billy started targeting everything that seemed to be a weak point for his sisters, as whenever he touched them, they'd moan even louder.

With his enhanced senses, Billy could see that his sisters were rubbing up against each other as well as kissing whenever they managed to get close enough, which caused Billy to get a little sadistic as he sped up whenever they got close to kissing.

Thanks to his superpowers, the girls quickly came, and it was finally time for Billy to show them what it meant to tease a man of lust for three solid weeks straight!

Rising up and forcing the girls on top of one another Billy started fucking both of them at the same time which greatly drained his stamina but he didn't care as thanks to his lust being his prominent trait whenever it comes to powers Billy could last far longer than others.

Well, that and energy drinks are amazing, especially when you get them for free, as having super speed is something that can apparently be deadly if he doesn't consume enough calories, and these had more than enough to last him a single day.

Which kind of sucks, as he needs them to last a week, but whatever, his stockpile didn't mean anything to him at this moment, and Billy was going to make sure his sisters knew just how bad of an idea it is to constantly mess with him!

Fucking both Stephanie and Danni at the same time is interesting, as even though he already knows how they feel, it's interesting to see just how much they love him and each other, as whenever he switches, he could hear them pout as they playfully attack the other.

It was also funny to hear Stephanie try and act like a queen as she punishes Danni for daring to go against her even though their brother is in complete control over everything, and this just makes it a lot more fun for Billy.

Reaching his limits, Billy pulled out of them, which weirded out the girls, as every time they've been with Billy, he's never done something like this before, and they were curious to see what he's doing.

Billy grabs both of his sisters and comes all over their faces, which annoys them as they didn't enjoy the feeling and were very vocal about it. "What the hell! Why'd you do this!? Do you have any idea how annoying this is going to be to clean!" Both Danni and Stephanie shouted at Billy, who apologized to the girls and quickly grabbed some tissue to clean up his mess.

Now that Billy's fuck-up was a thing of the past, his sisters want to punish Billy even more, as they wanted him to just watch as they got it on with one another.

Which didn't really work, as he knew what they really wanted, considering how they entered his room and how, no matter what he did, they seemed to be very into everything he was doing up until his major fuck-up.

Billy, with an anger in his eye, suddenly appears before Stephanie and Danni as the two went from making out with one another as they pressed into each other and rubbed each other's pussies with their hands as well as bit into each other's necks.

Now they were suddenly lying down on their backs, legs spread apart as Billy turned his fingers into a vibrator as he moved in, out, and all around. Before either of them could even wonder what was going on, they started moaning harder than they ever thought they could before as Billy made sure to hit the right spots over and over again within seconds.

"Okay, not that I'm done with the warm-up." Billy pulls out his hands and has the girls lick up their own juices until his fingers are somewhat clean. "Let's get back into it!" Billy said while licking his lips as he began fucking Danni as slowly and passionately as he possibly could just to mess with Stephanie, because, you know, why not?

Stephanie grabs and holds onto Billy's neck as he holds her tight in the warmest hug he could possibly give as the two make out with one another as Billy pumps in and out of her very slowly but with a powerful and sudden thrust that causes her to jump every time.

While Stephanie pouted, she crawled over to Danni and looked at her fiancée with admiration for how beautiful she looked but also jealousy, as she would have loved to swap places but knew she had to wait.

Stephanie, meanwhile, was losing her mind, as anytime she began to think of something, it seemed like Billy was hitting her reset switch, as every time he slammed into her, she would forget anything that might have been going through her mind.

As Danni shuddered and bounced around drooling all over the place, his drool went all over Billy's bed, wall, and sister as well as her own breasts and face whenever she and Billy parted lips so he could breathe normally before he went right back to kissing.

Or at least that's what he would have liked, but he saw his sister steal Danni's lips from him, and taking a look at her, Billy saw that she was rubbing her legs together in great anticipation while also fingering herself with her right hand.

Seeing this just made Billy grin as his desire to mess with his sister grew even bigger than it already had as he began wanting to hold back cumming as much as he could just to see what Stephanie would do.

But things didn't go as he planned; he reached his limit after five minutes and came inside Stephanie as hard as he could and pulled her away from Stephanie to give her a final kiss as he pulled out of her.

With zero hesitation Stephanie climbed over Danni and presented herself for Billy with a pleading look in her eyes as she pulled her pussy apart, revealing just how wet she truly was. "Please... Big bro, can you please hurry up and fuck me already!"

Billy was already inside Stephanie and fucking her before he even knew what was going on but didn't really care and sped himself up as he started fucking her as fast as he possibly could since he knew that's what Stephanie liked even if she'd never admit it.

Two minutes into fucking Stephanie, Danni wakes up and sees what's going on as Stephanie was over her and her breasts were rubbing against Danni's as fast as Billy could fuck, which, considering he was still using his powers, was pretty darn fast.

Danni grabs Stephanie by the neck and pulls her in for a deep and romantic kiss, which just makes the two feel even better, as they were making out with the woman they loved as well as rubbing against each other as fast as possible.

Because of just how fast he was going, Billy lasted far less than with Stephanie, but neither girl knew that, as Danni just woke up and Stephanie was losing her mind over what her brother and fiancée were doing to her.

Cumming inside Stephanie just as hard as he did with Danni. Billy was finally feeling normal again, which was still really horny, but he knew neither girl could last any longer than they had if he still wanted them to be sane, at least.

"Alright, it's been fun, but I have to clean my bed now, as well as all of us needing a shower." Billy said as he kicked the girls out of his room, only to later join them both in the shower as they made out and then started taking care of Billy like a king.

Honestly, Billy could get used to this type of feeling, as it made him feel very special and at the same time superior to the two girls, but he quickly gave up that feeling, as he didn't like how he was slowly becoming dominant in this relationship, as he still wanted to treat the people he cared for with love instead of like they were tools for him to use.

When they were finished, Billy left the two girls mumbling something in the shower as they tried to help each other stand up as their legs wobbled.

"Life is good, but as good as this is, it's sadly not the life I really want." Billy thought to himself as he looked at his phone and groaned upon seeing just how long it would take him to go from being a newcomer to an agent, which would let him help at least a bit more than he does now.

Meanwhile, unbeknownst to him, the girls were watching everything go on, and they've begun seeing their teacher in a brand new light as they've realized just how hot he can be along with just how dominating.

The only one to have any problems was Tamara, and that was because she was a fan of dominating others versus being dominated.

Also in the den of the night, the crate of vials that started Billy's shift in life has finally gotten some of the crates that they could get away with, and the big boss is wearing dark armor resembling a dark lord from fantasy and a power suit.

They hold out their arm and begin **** out the nearest minion, who is ten meters away from them, as well as slowly forcing them over to them. "I. AM. MISSING. THREE. VIALS. WHERE. ARE. THEY!!!!"

The dark master said through an electronic voice modifier that they had the power to alter their vocal cords, but no matter how artificial or natural they sounded, they were very intimidating, as when they cracked the neck of the poor minion, someone immediately stepped forward and began screaming for everyone to empty their pockets along with checking to see if they might have dropped them somewhere.

Sadly for them, they couldn't find the missing vials, and their master wasn't pleased at all over someone stealing what was rightfully theirs as they snapped at another minion. Thankfully for the leader, it wasn't him, but unfortunately it was instead his best friend.

"I. WILL. LET. YOU. OFF. THIS. TIME. BUT. NEXT. TIME. I. FIND. ANYTHING. MISSING. YOU WILL. ALL. PAY. THE. PRICE!!!"

Storming off while flipping their cloak in a way that for anyone else would look super lame, but they make it look super intimidating as they suddenly vanish into the night, earning great fear and admiration from all the crooks inside the abandoned warehouse on the other side of the city.

Meanwhile, back at home, Billy had injected himself with the last mental vial he "found," as he didn't know what it might do, but he did know that he didn't want something like this remaining in his room any longer than it already had.

"With this my anxiety should fall back to normalish levels for a hero in the making who's done some shady things in their past." Billy thought to himself as he threw the vial as hard as he could at one of his neighbors, as finding something thrown at their house was very common.

Before falling asleep, Billy made a plan to speed up his plans as he began thinking about finding a way to get his former teachers and principal, along with the vice principal, on his side, which should get him more reputation than he does by just being a teacher's aide.
