Lucy had thought it all through carefully. She knew that she was as guilty as Jack was for what she had done with some of the students in the school. But Jack had tried to be vindictive and blackmail her, knowing that he had done the same thing she had. He was an idiot to let her find out what he had done with Chloe Finch. He was a bigger idiot for believing she was now on his side. She was going to destroy him. Did she feel bad that Chloe, who was a nice girl, would maybe get used along the way in her plan? A little. Did she feel bad that Greg was going to get humiliated for a second time in her plan? Not in the slightest.

First she needed to get Greg to agree. She wasn't concerned about Chloe; from what Jack had said, Chloe was likely to do anything he asked her to. But she needed to hook Greg, and it shouldn't be too difficult.

She had some free time after her first lesson of the day, and she emailed Mr Kline, who she knew was taking a Science class that Greg should be present in, to ask him to send Greg to her classroom after first period.

Greg had no idea exactly what Miss Riley wanted, but he was interested to find out, given how things had ended at her Sex Education lesson a week prior. All he knew was that she had wanked his cock and sucked his cock, to orgasm both times. He was so blind that he didn't even register that she pitied him and almost openly mocked him both times. He simply saw it as something that she enjoyed. He reached her classroom and knocked, and heard her call him in.

"You wanted to see me, Miss Riley?" he asked.

"Yes, come in, Greg, and sit down," Lucy replied, gesturing to the seat in front of her desk.

She knew it would be easy to seduce him. She was, and always had been, well aware of how much many teenage boys, particularly the 16- and 17-year-olds in the Sixth Form, looked at her during lessons. Watching her ass, her breasts, her legs as she moved around a classroom. She needed to distract Greg from whatever he was thinking before he came to her classroom.  She perched on the edge of her desk at the head of the class and slowly, deliberately crossed her legs, making a big show of it and making sure the swish of nylon on nylon could be heard. It worked. Greg's eyes were on them in a flash, until she cleared her throat, making him snap out of it and look up at her face.

"Greg, I just wanted to speak to you, as I had been thinking about how things ended after that Sex Ed class last week."

Greg nodded, saying nothing, unsure where she was going with this.

"Now, I am sure you have not said a word to anyone," she continued. Greg shook his head to say he hadn't, which he was, of course, lying about, as Lucy carried on. "But I also realise that I wasn't especially fair to you that afternoon. I did make you look a bit silly in front of the class. You did deserve to be called up for how rude you were to Ryan, but I shouldn't have kept on at you like I did. So I am sorry for that."

"That's alright, Miss, what we did after the class finished helped make up for it!" Greg chirped back.

Lucy had to force her smile back and stifle her laughter...he actually was grateful for the quick wank she gave him and the pity blowjob, and didn't even notice her mocking tone about how quick he was on both. This was going to be easier than she thought. "Yes, that's what I was going to come to. It's bothered me since I made you stand and watch as I let Ryan have sex with me. So, I wondered if you would let me make it up to you?"

Greg couldn't believe his ears and stammered, "Errm, well... yes, Miss. I mean, yes, if you feel bad, you can make it up; I mean, I would be happy to. Errr, I mean, how?"

"Well," Lucy said. "You and Ryan are not the only students in the school to have got involved with a teacher. And I am not the only teacher in the school to get involved with a student. One of your classmates from that day has been coached by a teacher as well."

Greg's eyes widened, wondering who it might be. Miss Riley continued.

"I was wondering if you would like to join me, with them, to show what we learned in my class properly...you were paying attention in my class, weren't you, Greg?"

"Of course! ...I mean, yes, Miss Riley, I was paying attention."

"Good! Well, I need to speak with the others, but I am pleased you want to join in. I will let you know where and when... discreetly, of course."

"Yes, Miss Riley."

"And Greg, I mean, discreetly, mind you. If you don't understand that word, this doesn't go ahead at all, understand?" She checked.

"Oh yes, Miss, of course," Greg replied. He was too stupid, and too blinded by his own admirable, if misplaced sense of self-confidence and ego, to not see Lucy's proposal for what it was: an obvious trap and something he should avoid at all costs. But 17-year-old boys think with their cock, not their brain, a lot of the time.

Lucy was good friends with Miss Roberts, the Drama teacher at the school. She knew that on Thursday, she would be on a field trip, taking her senior class to the Theatre to watch a production and look at the backstage areas and preparation of a real theatre show. Her drama studio would be free. She caught up with her in a corridor and stopped her. "Helen, can I have a quick word?" Lucy called.

"Sure, Luce, what's up?" Miss Roberts said, stopping.

"I know you are out of the building on Thursday with your exam group, so I guess the Drama Studio will be empty all day?" she asked.

"Yes, it will be. Why?" Helen replied.

"Oh, I am doing a project with one of my first-year groups, and we are going to be making a world map, and I will need a big floor space to set it on so we can move around it and discuss," Lucy lied. "Thought your studio would be big enough; we don't need the Assembly Hall or gym; they are too big and probably already in use. The Studio seems ideal."

"Oh sure! Of course," Helen beamed. "Sounds like a great project for them! Here," she said, handing some keys to Lucy. "Take my spare keys. I normally lock the studio overnight, so on Thursday morning it will be locked when you come in; use the spare set to let yourself in. Just remember to lock up again when you leave."

"Oh, absolutely. Thank you, I appreciate it, Helen." Lucy said, grateful that her plan was starting to take shape.

Later that afternoon, Lucy got herself mentally prepared to let Jack know that the arrangement was on, having to pretend to like or in any way tolerate him. She opened her email and wrote: Hey You! I have Greg on board, thankfully! I also have use of Helen Roberts' drama studio this Thursday so that we won't be disturbed. Does 12 o'clock work? You got Chloe to agree? Lucy.

His email reply followed a couple of hours later: Hey Luce, of course Chloe is on board; she does anything I say! Thursday is good, and 12 is fine, around lunchtime, so I don't have classes to rearrange. Looking forward to it; glad you came to see things my way! Jack

Lucy caught Greg in the schoolyard and mentioned Thursday lunchtime to him. He made note, and she asked him to meet her at her classroom just before 12.

On Thursday, at 11:50, Greg sheepishly made his way to Lucy's classroom. She was waiting for him. "Hi, Miss Riley, am I too early?"

"No, not at all, just on time. Come with me," Lucy replied.

They set off to the other side of the main building, to the Drama studio. Lucy had already been in there first thing. She knew that they had a video camera in there to use for recording their Drama performances and watching them back for analysis. It was always on its tripod in the corner of the room. That wasn't unusual. Lucy had angled it and zoomed slightly toward the Desk that Helen used at the front of the studio, and she set it to record. She knew that the battery life on it was good for several hours. Also, the red record light was on the side facing away from where it was pointing, so nobody would notice that it was on. Lucy unlocked the studio with the keys she had been given and led Greg in. They waited silently for Jack and Chloe.

Jack led Chloe into the room. She wasn't a bad girl, but she had been blinded in adolescent fantasy by Mr Ross, and loved the attention he showed her. She was proud that he wanted her to do this special thing for him. Chloe was a bit taken aback when she saw Greg was in the room. She didn't like him all that much; he was a bully, but Mr Ross assured her that he was a changed man and that Miss Riley was keen for all of them to have a nice time.

"Glad you could make it!" Lucy said, closing and locking the studio door behind them. "Chloe, you seemed so confident and knowledgeable in my Sex Education class. Mr. Ross has told me why that was. I was impressed, but he tells me I would be even more impressed if I saw how well you have been doing." Lucy said to Chloe, sounding very caring, yet curious and seductive.

"Yes, Miss," Chloe said, as Jack smiled proudly.

"Come here, Chloe," Lucy said, guiding her strategically to the desk at the front of the Studio. "Let's take a look at you."

As they reached the desk, Jack followed behind and bent Chloe over it. Reaching under her green plaid school skirt, he tugged on her panties and lowered them to her ankles, leaving her exposed to the room. Greg stared open-mouthed. He had always fancied Chloe; she was one of the more confident and pretty girls in his year group, and he couldn't hide his erection in his trousers, seeing her brown hair falling over her face, and her pussy exposed to him as Mr Ross held her in his grip.

"Let's show them what you can do," Jack said, as he freed his hard cock from his gym shorts. He ran his fingers through Chloe's slick lips, making her squeak with arousal as he did. "Look at her, Miss Riley," Jack said, holding his fingers up, showing her how wet Chloe was. "Soaking wet like a good, well-trained little slut, come and see."

Lucy knew she had to do as much as Jack asked, to not make him suspect foul play, whilst staying out of shot as much as possible. It was inevitable she would be in shot sometimes, but she could fix that later. She approached Chloe and inspected Jack's fingers. "Wow! So wet, Chloe, you clearly understood what I was talking about when we discussed arousal in class!"

"Oh! Yes, Miss Riley," Chloe moaned as Jack carried on stroking her wet pussy.

"Let's make sure he is ready for you," Lucy said, mentally preparing herself. She crouched, her skirt riding up, revealing her garter as she did, and took Jack's cock in her hand, stroking the length of it, making him gasp. With her other hand, she touched Chloe's leg and leaned in, flicking her clit gently with her tongue. The young girl cried out at the feeling of Lucy's tongue teasing her most intimate area. "I think she is ready, Mr Ross, and you certainly are." Lucy purred, guiding Jack's cock to Chloe's wet snatch, pushing him inside.

"Oh Fuck!" Jack cried out and held Chloe's hips, fucking her roughly and without any particular finesse, over the desk, as Lucy stepped back, out of camera shot.

She turned to Greg, who was watching what was happening, and she could see the bulge in his trousers. Ignoring how sick it made her feel, she stood alongside him. "She's taking it so well, isn't she?" Lucy asked him.

"Yes, Miss, very well," Greg replied, transfixed by it.

"Let's help you out here; you must be aching," she said, putting her hand against his cock straining against the fabric. She unzipped him before he could protest, and stroked his cock as it sprang out of his pants. He shuddered as she jerked his cock. She knew it wouldn't take long, based on his last performance. But she hurried it along anyway, sinking to her knees and taking him fully in her mouth, swirling her tongue around his tip, and within a couple of minutes, he spilled his load in her mouth, with a loud cry as he did. Feeling proud of himself, he didn't even register how little effort it took to get him there.

Meanwhile, Jack's rough fucking of Chloe had brought her to orgasm, and he carried on riding her through the waves of it. "What do you reckon, Miss Riley?" he grunted. "A good student or what?" he asked arrogantly.

"A very good student," Lucy replied. "She is doing so well."

"Oh! Oh my god!" Chloe cried out as another climax hit her hard.

"Do you like that?" Jack asked Chloe, not relenting.

"Oh, yes, I love it!" Chloe managed to say back.

"What do you call me?" Jack asked.

"Sir! Yes, sir. Thank you, sir!" Chloe squealed.

"I think Miss Riley should come and have a turn; she loved it when I did this to her as well," Jack suggested. Lucy wanted to keep up the pretence and also couldn't deny that, as much as she didn't like him, he had made her come when he fucked the other day.

Lucy approached the desk, knowing she couldn't stay there long. She bent over next to Chloe, and lifted her skirt, pulling her knickers to the side, granting Jack access. He pulled himself free from Chloe and drove his cock hard and deep into Lucy. "Oh! Oh Fucking hell!" Lucy couldn't help but exclaim as he plowed her cunt hard. He instructed Chloe to touch herself whilst he fucked Lucy.

Greg, like a rabbit in headlights and a million miles from the stud he bragged about being to his friends, just watched. Not even considering approaching to join in, as he wouldn't know what to do if he did. The scene in front of him, Mr. Ross having sex roughly with Miss Riley, and Chloe Finch fingering herself next to them, made his cock strain hard again.

Lucy knew she needed to get Jack back inside Chloe. She twisted her body and turned to face Jack, panting as he fucked her. "I think it's only fair that Chloe takes your load; she’s the one here to show what she can do?" she said teasingly to Jack. "It's going to be a big load, I am sure," she said, stroking his ego.

Jack nodded and pulled out of Lucy, pushing himself back into Chloe. He grunted and gripped her hips hard, and roared primally as he finally spunked hard inside her, making her moan at the sensation of it filling her. "Oh, that's so fucking good," Jack said proudly as Chloe breathed heavily on the desk.

"Such a good girl, Chloe!" Lucy exclaimed. She still wanted to humiliate Greg some more and could see him nursing his less-than-impressive erection. "Think she can take some more?" she said to Jack, gesturing to Greg.

"Oh, I think so, Miss Riley," Jack smiled and beckoned Greg over. "In you go, big chap, show her what you've got!" he said, slapping Greg on the back.

Greg stood paralyzed until Lucy led him forward and took him softly in her hand, and she guided him into Chloe. He had watched enough porn to have a vague idea, and he started pumping clumsily, feeling the squelch of Mr Ross's load already inside Chloe. He barely lasted a minute. "Oooh! I'm gonna...I'm gonna!" he whimpered as he ejaculated inside Chloe and pulled out of her, looking embarrassed.

"Jesus, lad," Jack laughed. "We will need to do something about your fucking stamina next PE Lesson!" he mocked.

The quartet got back into an acceptable state of dress and cleaned themselves up. Jack and Chloe made their way out of the studio. Lucy remained with Greg.

Lucy turned to Greg, who was mortified. She looked at him sternly. "Right then, mister, enjoy that?" she asked.

"Err, yes, Miss, thank you, Miss Riley," he stuttered back.

"Well, just to let you know, I know you couldn't keep your mouth shut last time. I know that you blabbed when I told you and Ryan to keep it to yourselves," she said, looking him dead in the eye. Greg gulped and nodded. "Well, this time, you will never speak of this. I know you won't. Do you know how I know you won't?" she asked.

Greg shook his head, his ego completely stripped.

"Because I know you will not want anyone knowing that not only did you last no more than a minute getting an unenthusiastic blowjob from me, but you also blew your pathetic load in less than 60 seconds the first time you got near a girl's pussy. Chloe will say nothing, as she is as embarrassed as you. Mr. Ross will say nothing. But do not for a minute assume that I will say nothing. You have seen what I can arrange. It won't come from me directly, but so much as a suggestion that you have told anyone, and I will make sure every single one of your friends knows what a pathetic, premature ejaculating little boy you are. Clear?"

"Yes, Miss Riley. I won't say anything, I promise." Greg said, absolutely defeated.

"Good. Now, on your way," Lucy said, pointing to the door. Greg left. Leaving her alone in the studio. She went to the video camera and took out the memory card with the raw footage, locked the studio and continued with her day.

That evening at home, she spooled through the footage. It was wonderful. Clear footage of Jack having sex roughly with Chloe. The bit where she licked Chloe's clit and guided Jack into her was sexy as hell, and watching Jack take her roughly was also pleasing to watch back. But those bits were not important. She spent several hours editing the footage, cutting out bits she didn't need and removing the sound. Until she had a video of around 10 minutes, purely consisting of Jack having sex with a 17 year old student, in her uniform, on school grounds, in school time.

She watched the clip back. Got you, you fucker, she thought gleefully to herself

She got into school early the next day. She went to Mr Jones, the headmasters office, with the disc containing the footage. She knocked on his door.

"Oh, come in, Lucy, nice to see you so early. Everything ok?" Mr Jones asked.

"Sorry to bother you, Sir," Lucy replied. "I don't really know what to say. But I was in Helen's Drama studio yesterday whilst she was out on the field trip. She let me use it as I needed some large floor space for a project with my Year 7 group, and..."

"Yes, is everything alright Lucy?"

"...and well, I was going to use the camera in the studio to film the children presenting their projects, and I found this footage on the camera." She said, handing the disc to the Headmaster. "I just want to say that I would be grateful if, once you have seen what is on here, that you leave me out of this. I don't want to get tangled up in any scandal, and I just wanted to do the right thing by giving it to you." She said, sounding as innocent as she could.

"Well, I have no idea what is on here, but ok, yes, I can keep you out of whatever it is. Should I watch it now?" he asked.

"I think you should, sir."

Mr Jones put the disc into his laptop, and his mouth hung open as the damning footage played. He closed his laptop in disgust.

"I did the right thing bringing this to you, didn't I? I wasn't sure I should get involved, but I thought I had to."

"Yes, Lucy, you have done the right thing, and I can see why you want to be kept out of this. Don't worry, I won't mention your name," he assured her.

"Thank you, Sir. I better get to my classroom."

"Yes, off you go. Thank you.”

Lucy almost skipped down the corridor, gleeful in what she had done.

Jack put his office phone down, having just been summoned to Mr Jones' office, unsure what he wanted. He went straight there. On arrival, he was called in, and the Head looked stern. He was offered a seat.

"Mr Ross, thank you for coming up so quickly," Mr Jones said. He had been put in a very awkward position. He had considered calling the police, but technically, Chloe was over 16 and was of legal age, so he wasn't even sure if it was a police matter. It was certainly an abuse of his position of power as a teacher to have relations with a student. And also, the local community had already been up in arms about the school beginning sex education lessons. And this scandal would create a frenzy about why they shouldn't have brought it to the classroom in the first place. He had decided to try and get rid of the problem as quickly and quietly as possible.

"Of course, Sir," Jack replied. "What did you want to talk to me about?"

"I need to show you something that was anonymously given to me," he said as he hit play and turned the laptop screen round to face Jack. Jack watched the footage and felt like he had been punched in the stomach.

His mind raced. That Bitch! he thought. He quickly figured out what had happened. He tried to quickly think of how he could get out of this and bring her down with him. But he realised the footage didn't show her. As far as the footage was concerned, it was a private sex tape between him and Chloe; nobody else involved. He had no physical or circumstantial proof of Lucy doing anything or being involved in anything. She had him checkmate. He sank into his chair.

"Erm...Mr Jones, I...." Jack stammered, not knowing what to say.

"Look, Jack," Mr Jones said. "You and I both know this isn't good, and you have put me in a terrible position here. The school and I could do without the aggravation this will cause. Chloe hasn't, as yet, put in a complaint, and from what I can see from that awful video, she was a willing participant. I won't ask why that is. So I will say nothing to the authorities if you just leave quietly. I am not even going to fire you; I will give you the opportunity to do the right thing. I think you would be wise to read and sign this," Mr Jones said, passing a piece of paper to Jack.

Jack read what was passed to him. Mr Jones had drafted a resignation letter on behalf of Jack, and there was a space at the bottom for him to sign it. It waived any rights to any further pay. He knew he had no choice. He signed the letter and handed it back. "I will pack my desk, Sir. And I am sorry," Jack said, defeated, and wondering how he ever let his guard down enough to let Lucy Riley get the better of him.

He slowly walked to his office at the Gym, picked up his personal belongings and took them to his car. On the way, he saw her. Lucy was looking out of her classroom window, smiling wickedly at him, and even gave him a little wave, enjoying her triumph.

Later that night, still high on her victory and on the power that she had wrestled back after having it stolen from her by a man she had always hated, Lucy fired up her laptop, and hit play on the full, unedited footage, and watched it back, every sordid minute of it. Jack defiling Chloe, Chloe moaning as Lucy licked her clit, Jack fucking her roughly as Chloe watched. Fuck with me, and find out what happens! Lucy thought to herself as she masturbated hard, cumming loudly at what was surely going to become her new favourite material for her private time.
