1.
It was another hellish day at school for young Alex, a skinny and pale 17 year old with messy black hair. She had recently came out as trans a few months ago and since then the local school bullies, a band of jocks lead by Mike, captain of the football team and the favorite of the teachers, had made her life impossible. Alex one and only friend was a classmate named Ana, which whom she had been paired in some recent class projects recently and had shown to be the only person in the whole school who didn’t actively tried to make Alex’s life a living hell.
Speaking of, it was close to noon on that day when Mike ambushed Alex in her locker.
“Hey there freak” he said with a dumb smirk, much to his friends’ delight “I heard you were eyeing my girl, Suzy early”
Suzy was, indeed, Mike’s girlfriend and cheerleader captain. Alex had an impossible crush on Suzy, even tho it was pretty clear the cheerleader follow her boyfriend’s opinion on poor Alex.
“C’mon Mike, that’s not truth” answered the girl.
“Oh, so I’m lying then?”
“N-no, just maybe you heard wrong…”
“Oh, ok then, so I’m stupid is what you’re saying”
Mike pushed Alex against her locker while the other jocks cheered in the back.
“You know? I don’t give a shit what you call yourself now, I’m still gonna knock your lights out, ya hear me!?”
Before Mike could throw a punch, something happened inside of Alex, something she had never felt before. To everyone’s dismay, she began rapidly expanding. Her shirt and hoodie soon started squeezing her torso, her baggy jeans became tight shorts and her shoes disappear below her feet. Eventually her head smashed through the roof while her whole outfit exploded, leaving her completely naked. She kept going and going until her head went through a second roof, exposing her to the hot spring sunshine. She looked at the sky in disbelief completely paralyzed. She could feel the two layers of concrete cutting her at neck hight and waist hight and soon started to hear the screams of the people inside the building.
Panicking, Alex started to shiver, making the whole roof fall around her. When the dust settled, she was standing in a giant hole that went through the two floors of the school. She could see all the students and teachers running away in the second floor and when she looked at her feet she saw Mike and his crew standing up from the wreckage.
“What the hell…” the jock started to say when he got cut off by the amazing sight before him.
There it was the small little twerp he enjoyed kicking around, bigger than the town’s square statue, fully naked, with her magnificent member hanging between her legs.
Completely at a lost for words, Mike felt to his knees.
“What are you doing man? Let’s make like a tree!” screamed at him one of his mates.
Seeing the little jock that made her life miserable being so struck by her figure alone gave Alex a huge rush going up her spine. A rush of something she had never felt in her entire life: a rush of power. Without even thinking of it she crouched down, extended her hand and cut off Mike’s little crew’s escape.
“You aren’t going anywhere” she said with the coldest tone any of them had ever heard.
In one sweep she scoop them all up in her hands. They started squirming trying to get free, but her strong muscles kept them in place. The sight of all these big guys make Alex feel aroused and she started feeling her dick twitching.
“Y’all made my life hell” she mumble, tho perfectly clear for any of them “I hate you all”.
Without saying anything else, she scooped a handful of jocks into her left hand, squeeze them tightly and throw them into the air with all her strength, like pitching a meaty baseball. A few seconds later they started to fall down around her, like a rain of tiny people. They all hit the payment at full force, practically imploding in the process. A few unlucky ones didn’t die tho, and Alex quickly disposed of them with her feet. The feeling of their bodies cracking under her soles send shivers up her spine once again and she finally sense her cock get fully erect.
In her right hand she held the remaining jocks, crying and pissing themselves. Without skipping a bit, Alex brought her left hand at full force, clapping them all out of existence. Their bodies exploded in a paste of blood and viscera that rain upon the tiny little Mike, still kneeling below her former victim. His eyes were red from crying, his body was shivering like a leaf and he had peed and shit his pants. And yet he was unable to move when the giantess above him crouched once again.
“ugh, still here? Gross…” she said.
The guy couldn’t even scream when two pair of fingers came before him and flick him at break neck speed. His body was sent flying across what remained of the hallway and splatted against a wall. He was dead before that tho, his spine shattered into a million pieces due to the shear force of the giantess’ fingers.
Once the squad had been dealt with Alex looked around. The school grounds seemed to have been emptied. Yet, she suspected where was everyone else.
“It’s payback time” she thought while heading for the gym.

2.
The school gym was a separated building that stood behind the main one. Under any case of emergency, everyone was instructed to seek refuge there. Inside there was a boiling pot of people, students from all ages chatting with each other, discussing what had happened a few minutes ago. Despite the sightseeing of a giant woman in the school grounds, the most accepted theory among everyone was that something had crashed against the school. It was the most logical answer after all, everything else was being attributed to hysteria and mass delusion.
In the staff area, the teachers weren’t much better than their students. Principal Evans, and old fart who reassembled a pug tried to put some order.
“Have we called the authorities yet Miss Hopkins!?” He screamed at the top of his lungs.
His assistant, a younger, more wider woman with a very conservative dress and hairstyle, a reflection of her own views and personalities, answered back.
“We tried, but the phones are down and there’s no signal, it has been like that for the entire morning” she said with her soft voice.
“Then someone go out there and find help!” the principal yelled “It’s not like Godzilla is attacking the city! GO!”
“Y-yes Sir!” said the chubby woman.
With quick steps Miss Hopkins left the staff room and went outside the building. She didn’t made two steps before stopping dead on her tracks. Before her, stand the giant figure of Alex, looking down on her.
“Oh my! Mister Robinson!” she screamed “Is that really you? How could this be!?”
Alex frown and picked up the frozen woman who started screaming at the top of her lungs.
“Mister Robinson please! Put me down!”
When she was face to face with the giantess, the later spoke.
“When I came out you humiliated me. You punished me for trying to used the women’s bathrooms. You called me a perverted boy. Said I was just dressing up to spy on my classmates. What a sick fuck you are.”
“I… I… don’t-” before the older woman had time to answer, Alex popped her into her mouth and used her tongue to place her right below her molars.
With a quick press, Miss Hopkins exploded under the strength of the jaw, liberating all her inside juices into Alex’s mouth. She swallowed without much thought.
“ugh, disgusting bitch” she mumble.

Inside the gym things hadn’t changed. Suzy and her squad was sitting at the top of the benches looking down on the rest of the students.
“It’s so unbelievable they make us stay in here with this weather” She said while waving some air with her hand.
“Yeah right?” said Samantha, her second one “At least turn on the AC, for crying out loud”
“So, what do you think happened anyways?” asked Sandra, the newest member of the team.
Suzy sighted.
“Obviously a plane crashed into the school, idiot, didn’t you listened to the principal?”
Sandra looked away trying to avoid Suzy’s gaze.
“Oh yeah, you’re right… it’s just that it doesn’t sound possible that a whole plane had crashed down on the school and didn’t… like kill us all or something”
“Oh my god girl, you’re so stupid, of course it wasn’t a big plane, it was one of the small ones, like the ones you see on the beach flying signs and stuff”
All the other girls started nodding and complimenting Suzy. She inflated her chest with pride. It didn’t happen often she had a chance to actually show off her brains.
The round of glazing got interrupted by a loud rumble. The entire gym went silent. Quickly after there was another one. And then another one.
“What the hell is that?” said someone in the crowd.
Like an answer to the question, the gym’s door got blasted away by a massive truck. The ceiling above gave in and the entrance was definitely blocked. Next, the entire roof got pulled away by an impossible force, making ruble fall unto the scared crowd below. Among the confusion, a giant head peak inside from above.
Alex felt like she had kicked an anthill. She saw hundreds of tiny bugs running around to nowhere, clashing against the blocked doorways and mindlessly jumping on top of each other. She felt almost entertained by the sight, and her fun grew larger when the tiny people started to take notice of her presence. Completely dominated by their instincts they started screaming and shouting, slamming themselves against the walls and doorways. The windows were too far up and yet some tried to climb the basketball hoops trying to reach them. The few that didn’t fall immediately ended up falling to their deaths trying to reach the locked windows.
Finally Alex’s gaze meet what she was looking for. In the benches, her eyes met with Suzy’s, who was completely paralyzed with her jaw on the floor. Not in a million year the lead cheerleader expected to see the giant face of her disgusting little torture project looking down on her with the widest smile she ever saw on her face.
Without minding the other students Alex reached inside the gym and carefully grabbed Suzy. She didn’t made a sound. Slowly the giantess brought her to her face.
“Hey there cutie” said.
Suzy couldn’t form any words.
“What? Cat got your tongue?” Alex laugh. She brought her giant finger to the little lady’s head and gently stroke her hair.
The cheerleader snapped out of it.
“N-no, I mean, yes, I mean… I don’t know… what to say…”
Alex smiled again.
“Well, what did you said the other day?” she put her free hand under her chin and faked meditate for a second “Oh yeah, ‘get out of my sight, disgusting looser’? I think those were your exact words”
Suzy didn’t respond. Alex’s smile grew wider.
“It’s ok” the giantess continued “I’m not resentful. I don’t resent all the harassment, the slurs, the humiliation or the pain you caused me. I’m a bigger person now.”
She laughed at her own joke. Suzy didn’t.
“What? You don’t think I’m funny? Because I remember you laughing at me a lot, don’t you?”
Alex’s smiled faded out.
“I said, ‘don’t you?’”
“Yes, yes I remember” said finally the tiny woman “you’re pretty funny Alex”
The giant opened her eyes wide.
“Wow, you know my name? You know I’m not called ‘freak’ ‘looser’ ‘pervert’ or any of those horrible slurs you and your little bots throw at me all the time?”
“Yes, I mean… I didn’t… I didn’t thought…” Suzy sighted, she was desperate “I’m sorry Alex, I should have been better with you…”
Silence came between them. Then, Alex brought the little woman close to her lips.
“You know?” she started, washing her warm breath on the tiny cheerleader “I was so in loved with you. I loved your hair, your face, your body… you were literally perfect. But you hated me, and I hated myself because of it. I thought to myself ‘it has to be me, there has to be something wrong with me… it has to be my fault, because she’s without them’ and then I came out, and for a second I thought ‘that’s it! I wasn’t being myself, that was the problem! Now that I am myself, she’ll see me and accept me!’… boy was I wrong, wasn’t I?”
“Alex… I’m sorry-” Suzy started but got cut off.
“I know, I know. You didn’t mean it. But you know what? That actually helped me, in a way. It made me realize I wasn’t actually in loved with you, just with the idealized version of you I made up in my head. Not the shallow bratty doll you truly are”
Suzy felt Alex’s gaze going up and down her.
“So thank you, and I am sorry for putting you in that pedestal”
Suzy lifted her eyesight and for the first time she met Alex gaze. In there she only saw a lustful rage that iced her blood.
“I should have know bitches like you only have one purpose”
And with that, Alex lowered the tiny woman to her ginormous penis and started rubbing her up and down. In a second her cock turned fully erect and started pulsating, her veins pumping blood through the entire phallic tower. She quickly reached top speed and her legs started quivering in response. Her moans echoed around the premises, making all of the students below, who had kept mostly quiet up to that point cower in pain covering their ears. She was stroking so hard she almost lost her balance and had to grab to the wall of the gym to stand her ground.
For Suzy it was living hell. The friction and the pressure against the giantess’ skin had raised her temperature to inhuman levels and the constant rubbing pulled her skin up and down creating an extremely painful sensation. The only thing preventing the motion from tearing up her skin was her own sweat, which was working as a less than optimal lube. The little lady hadn’t stopped screaming the entire time, which made the giant one even more aroused.
“OH YES, FUCK, YES, KEEP SCREAMING YOU LITTLE BITCH” she yelled at the top of her lungs, which meant it was probably being hear by the entire town.
After a while, Alex finally felt herself reaching climax. When she couldn’t hold it anymore, she put Suzy on top of the head of her penis and shoot the thickest load she ever shot. Her pelvis motioned back and forth and a sea of white seed engulfed the broken body of little Suzy, drenching her from head to toe.
“Fuuuuck that was… amazing…” Alex mumble.
Next, and without much care, the giantess picked the body of the tiny cheerleader of the tip of her cock and casually throw it to the ground. Suzy fell into the solid pavement in a puddle of thick hot steamy white cum. She cuffed, still alive, tho her body was completely useless. All her bones where broken, she had no mobility in any of her limbs. In a matter of seconds to minutes she would drown in the pile of cum. And the giant goddess above her, the once puny victim of her abuses, didn’t even notice she was still alive.

3.
Inside the gym it was total mayhem. People were running up and down, some were crying, some even gave up all hope and started prying to the giant goddess. She, of course, didn’t care for any of this. She was still recovering form the best jerk off session of her life and needed a place to rest. She placed both her hands on the wall, and with a pretty slick hop, she jumped above it and landed inside the gym. The earthquake that followed sent everyone up in the air and back to the ground. A couple of poor dozens ended up plastered under her soles, turn to a red paste. Without minding her steps, she walked to the benches at the opposite side, turned around and started lowering her big huge ass.
The crew of cheerleader witnessed the fate of her leader completely baffled. Much like Suzy, they couldn’t even fathom what was happening. When everything ended, they didn’t even reacted. It wasn’t until the earthquake caused by the giant’s jump when they quickly came to their senses. They started going down the benches as fast as they could but the huge crowd below made it hard to move around. It wasn’t until they saw the huge shadow looming over them when they realized it was pointless to run.
Alex’s plummeted her ass on the benches with so little care her massive weight turn her behind into a meteor. The wooden structure didn’t hold a chance. It, everyone on it and some poor souls hiding below were instantly crushed by the massive ass of the young woman who leaned back against the wall and stretched her legs.
“You know, y’all could do something actually useful and massage my feet or something…” she said to no one in particular.
Most students immediately ignored her. They were too caught up in their desperate attempt of escape.
Frustrated, Alex rise her left foot and drop it with full might, completely destroying the basketball court below.
“I said MASSAGE MY FEET” her voice rumble the very foundations of the building itself.
Immediately everyone obeyed. Dozens upon dozens of tiny little hands started to grab unto whatever piece of skin they could at the giantess feet. But the skin was so thick it was like trying to massage a wall of concrete. Some started punching it, but it was the same result. Eventually Alex got bored.
“Yeah, it’s not really working guys…”
She was considering what to do next when a new feeling in her crotch gave her the answer. A new sensation building within her long shaft. With a wicked smiled Alex stood up. Everyone backed away immediately.
“A pity” she said “y’all aren’t as fun as I thought…”
And with a chuckle added:
“match is over, go to the showers team!”
Nobody really understood what she meant until they saw her grabbing her dick and aim it at the crowd. Next a golden boiling stream of piss erupted like a geyser and impacted straight on the crowd below. Those unfortunate souls in the direct path got carbonized almost immediately. Those who were closer to the stream got carried away with massive third degree burns and subsequently they all drown when Alex started moving the stream left to right, hitting everyone in the crowd. She was having a blast. After a few more seconds eventually the stream started weakening and finally it dried out. By that point the gym was covered in at least a foot and a half of piss, with many dozens of student’s bodies floating around. Some did survived tho, and were trying desperately for some fresh air only to be met with the strong stench of piss.
“Well, that might be all then” Alex thought to herself “except…”
Ignoring the remaining survivors, the giantess knelt right next to a double wooden door at the side of the gym. The door had a high number of corpses in front of it but didn’t budge due to a solid barricade on the other side. Alex, however, effortlessly punched through the door and the barricade behind and after some careful maneuvering managed to pulled out Principal Evans.
His old ass eyes immediately watered at the stench of piss and his attempts at covering his mouth and nose were all in vain.
“I knew you would be too coward to come out” Alex said with a grin “Do you mind the smell? Don’t worry, it’s about to get worse”
Before the Principal could talk, she grabbed his leg and bend it backwards until a loud crack was heard. The old man started screaming at the top of his lungs.
“There” she said, putting the old man in the ground “Now stand still”
Next she stood up, turn around once again and crouched above the wounded Principal, who at the sight of those huge ass cheeks opening up to reveal a magnificent butthole, was filled with pure terror and started to crawl away. Didn’t make it very far before a blast of methane gas hit him like a nuclear blast from above. Immediately started puking and coughing, unable to even open his eyes do to the corrosive particles in the air. Completely kneecapped, he couldn’t do anything against the huge turd that started coming out of Alex’s asshole. The giant lady pushed two times and the giant piece of shit fell free on top of her dear Principal who got completely buried under it.
“Ahh there you go” she said.
She grabbed some of the survivors who were lying around and used them to wipe her ass, only to casually toss them aside afterwards.

And then Alex looked around. The school was completely destroyed and both students and staff was mostly dead. For the first time in many years she felt truly good. But there was something still bothering her.
“I wish Ana had come to school today” she thought “we could have had fun”.
With no effort, Alex knocked down one of the gym’s walls and casually waked out of it.
“Well, I guess we can still hang out after school, I have somethings I wanna do with her” her attention got caught up by the distant sound of sirens, she smiled “we’re gonna have so much fun!”
