"Well, will she do?" A large green figure watched from a secret cctv feed observing a human sat at her desk. "Yes" the partner answered. "She's the perfect size, and a high enough authority for us."

"What's her background?"

"No children, separated from her partner and lives on her own. She is the perfect body for us. I'll go fetch!" The two figures giggled as Miss Burton sat at her desk, unaware she was being sized up, literally…

"Class 13B, apologies for my delay, I was slightly, occupied" Miss Burton chuckled to her self. Her hair was now styled in a fringe, a new look for her and the stomach and hips look slightly larger than when her students had last seen her. She clicked her neck as she stepped through the doorway before seeing the young TA at her desk. "And who may you be?" She questioned imposingly."

"Um, I'm, Sophie, I mean Miss Brooks. I'm one of the new TA's. I was just passing by when I heard the class getting a bit loud and thought I'd do the register for you. I'll, I'll be leaving now" Miss brooks said hurriedly. Miss Burton scared her and she wanted to get out of the classroom as soon as she could. "No." Miss Burton said with a toothy smile. "You will stay, after all I need to thank you for your help!" A wet fart then escaped from her bum, leaving a foul stench in the air. "Oh excuse me, I had beans last night for dinner, terrible wind." The students laughed quietly at the sudden outburst, whilst Miss Brooks nodded her head apprehensively. Miss Burton carried out the register, taking note of certain students when they answered, particularly Ameera. When the bell rang which signalled the end of form, the students began to mingle out of the room, until only the two teachers remained. There was an awkward silence, as Miss Brooks struggled to make eye contact with the intense Miss Burton, who was looking her up and down. Miss Burton then strutted over to the door, before locking it and then releasing another loud fart. "Oh please excuse me Miss Brooks. How very unprofessional of me!" She laughed. "It's, it's ok Miss. It's only human" Miss Brooks said uncomfortably. She really didn't know what was going on with the senior teacher and wanted to get out as soon as she could. "Oh yes, you could definitely say that!" As Miss Burtons belly growled. "I do have to thank you, Sophie…" as she stepped towards the young TA, "You coming in and settling my class down, what would I have done without you?" She giggled. "Oh really it was nothing, but I better be going Miss, I've got a class to get to."

"Oh don't worry about that, I've much bigger plans for you. Much more important than your pathetic career, and life…"

"Wha… what do you mean miss?"

"Well, let's just say my sister can't wait to meet you!" She groaned in delight.

No one else could hear Sophie as she screamed at the sight in front of her. The loud clamour of thousands of students moving around the building drowned her out. A blue light could be seen shining from Miss Burtons classroom. The last thing Miss Brooks saw…

As the day went by, the 3 girls were all sat in their maths class, which was being taught by Mrs Malhotra. She was an early thirties, tanned skin and tall woman. Dark black hair, brown eyes with pink lips, she was very attractive. She had an hour glass figure with big, thick hips and long sexy legs. She had been quite successful in her career and was already an assistant head at the school due to her performance. She was finishing the lesson on equations when she heard one of her students whispering while she spoke. "I can hear you Ameera! You can stay with me after class!"

"Ohhhh" she groaned. The bell rang for the end of the day and after a few moments only Mrs Malhotra and Ameera remained. "Well then Ameera, do you want to tell me why you think it's acceptable to talk over me when I'm trying to teach you and the rest of the class?" The teacher said angrily. "I'm sorry Miss, I had just realised I'd left my phone in my last class, and was asking the girls if they had seen it before we left."

"Well for one, she shouldn't have even been in your phone, and two, you could've waited until I'd finished talking to have your conversation. Go and get your phone then come back here, you can wait with me for half an hour and show me you've learnt your lesson."

"Yes Miss…" Ameera replied reluctantly. She got up and left the room, plodding down to her English classroom. She was about to go up the stairs when suddenly she bumped into the large frame of the TA Miss Brooks. The force nearly knocked Ameera to the floor but she managed to balance herself. Looking up at the TA, she suddenly felt a strange feeling. The woman who stood before her felt like she had a completely different presence than of earlier. Gone were her thick glasses which had covered the majority of her face, and without them she looked unrecognisable. Her clothes were also a lot more filled out now, almost as if she had gained weight since this morning. Before Ameera had a chance to question it, Miss Brooks sneered "What are you still doing here, shouldn't you have left the building child?" Her neck clicked as she addressed Ameera, stepping closer towards her. "Um, I'm just going to get my phone from my classroom, then I've got a detention with Mrs Malhotra."

"Oh do you? Miss Brooks grinned, "why don't I escort you to your phone, we don't want you running off sticking your nose in anyone else's business now do we? Then again, I do have a niece…" she murmured under her breath.

Ameera thought her luck couldn't get any worse, when she then heard Mrs Malhotra stomping up behind her, now she was really in it. "Ameera, I told you to go get your phone and come straight back, not stop and chat on the way!" Mrs Malhotra shouted before she came round the corner, then seeing the TA on the stairs. "Oh my apologies, Miss Brooks isn't it? I thought young Ameera was chatting to one of her friends and not following my instructions." Miss Brooks attention went from student to Teacher, looking up Mrs Malhotra eagerly, with a toothy grin. "Ah Mrs Malhotra, no need to apologise. If anything you're just the person I need. I was looking for a senior member of staff to come and help me in the staff room, but if you're busy with a student, not to worry."

"Well, we can postpone this detention if I'm required Ameera, go and get your phone and go home, but if I catch you talking again in my class the punishment will be severe." The maths teacher said.

"Yes miss, sorry miss" Ameera said as she scuttled off.

"Now then, how can I help Miss Brooks…"

The staff room was completely empty apart from the entry of the two heavyset ladies. "Tea Miss Brooks?" Mrs Malhotra offered. "Oh yes please, make it three cups. Miss Burton will be joining us shortly…" she chuckled to herself. Mrs Malhotra turned her back and began preparing the drinks. "So what was it you wanted my advice with?" She asked.

"Well the thing is, ever since I've been here I've found it hard to fit in, with the other staff and students."

"Well that's certainly normal, it's a completely different environment to what you would've been used to. It takes time but I'm sure you'll get there."

"I just wish sometimes I could be someone else, and live their life, someone comfortable in their own skin…"

Confused, Mrs Malhotra was about to question what the young TA meant when before she could the staff room door opened to the large frame of Miss Burton. "Ah Mrs Malhotra, so good to see you! Been keeping her busy sis?" she bellowed to Miss Brooks laughing loudly before turning around and locking the door. "Sis? I didn't know you two were related?" Mrs Malhotra said, now slightly uncomfortable knowing that she had been locked in. "Oh yes, couldn't you tell? We look so alike! Well not when we're wearing this meatbags anyway!" Both ladies belly laughed at the remark before Miss Burtons arse let out a fart. "Oh, there I go!" She giggled. FARPPPPP! "And me too!" Miss Brooks joined in. "What on earth is going on here!" Mrs Malhotra shouted.

"Oh we're just leaving everything out in the open! Don't worry Mrs Malhotra, soon you'll understand everything…" Miss Burton said with an evil look on her face. "Right, this is ridiculous, I'll leave you two to your stupid games but just know the head will be hearing of this!" Mrs Malhotra shouted before stomping her way to the door. "Move away from the door human." Miss Burton stood between her and the exit. "Your body is required…"

"What the fuck are you talking about!" Mrs Malhotra shouted, she was panicking now. "Well you see, this skin is great and all, nice and roomy, but it holds no power here, that's where you come in. You and your big, juicy body, god it's making my mouth water just thinking about it." Miss brooks let out, almost moaning in delight.

"Oh my god what are you…" the terrified human managed to let out. "I think it's time to show her sister, she's all yours!" Miss Burton giggled. The young TA reached up to her brown hair, brushing it to the side. A silver zip appeared and one of her chubby hands grabbed onto it whilst the other supported her wide waist. She groaned as the room was lit up with a bright blue light, almost blinding Mrs Malhotra. Dragging the zip across her forehead she took a minute to look on her prey, her eyes wide with excitement. She then put both her human hands into her scalp, and began tugging and pulling the fat face from her true form. The large green head sprung out, glistening with sweat from the constraints of the skin. She moaned and groaned in delight, freeing herself. All the while Mrs Malhotra was frozen in fear, Miss Burton was laughing manically. Once her head was free, then came the body. Her wide belly shook with every movement, as the TA's skin flopped to the floor. The beast inside stood tall, almost 8ft tall. It stretched its big large muscles, with its long sharp claws pinching the air. "I, AM, SLITHEENNNNN!!!." It cried. "OH MY GOD OH MY GOD" the shocked and terrified teacher cried out. She picked up a chair to try and defend herself, much to the amusement of Miss Burton. "Sister, let your hunt commence…". The Slitheen took a few heavy steps towards its prey, before it towered over her. It swiped the chair from Mrs Malhotras arms, leaving her thick body exposed. In a matter of seconds, the teachers cries were cut out from a claw around her windpipe, and her life was over.

An hour had passed since the slaughter. "Well, how do I look?" Mrs Malhotra twirled her body round in the staff room. "Human" Miss Burton replied with a chuckle. "Oh wait a minute!" PARPPPPP. Mrs Malhotra sighed as the flatulence left her jiggly arse. "That's better. Now, phase 2 of the plan can begin!"

"What shall we do with Sophie?" Miss Burton had the old skinsuit of the former TA in her hands, it was flat and crinkled up, hardly resembling the former human it had been only a few hours ago. "Give it here, I'll store it in this skins office. You never know, we may need her again!" Mrs Malhotra laughed. The two teachers took one last look at each other, ensuring both zips were concealed. Happy with their appearance, they unlocked the room before making their way down the corridor, farting as they did…
