A student's secret desires: Part 5

Alex's lust is rapidly changing his body and he is almost always seeking pleasure and release, and this time, he seduces his biology teacher, Miss Foster.

He approached the biology classroom with glee, he was more than ready for his next lesson. He couldn't stop feeling a major sense of pride over his accomplishments and his lust only grew more powerful as his dick rose again. His lust was becoming extremely strong by this point and was granting Alex superhuman-like powers. His balls were producing cum at an extraordinary rate and it was forcing him into and endless cycle as he constantly seeked pleasure and relief, it was quickly turning him into a monster as he lost all fear and all care for others. He continued to stand outside of the classroom for a short while whilst daydreaming about his accomplishments, but his trance was soon broken as the classroom door opened and his biology teacher emerged. Her name was Miss Foster and she was in her early 30's, was Asian, had dark hair, brown eyes, a small pair of tits, a cute ass, a thin figure and she was also quite short at around 4ft 10. Alex towered over her as she looked up at him with a beaming smile, seemingly happy to see him. She closed the classroom door behind her before asking "Alex, what are you doing here??? You should be on your lunch.". Alex's faced quickly turned to one of confusion as he replied "No it's not, it's fifth period...". Miss Foster laughed before correcting him "I love the enthusiasm Alex, but it really is your lunch at the moment." Alex continued to stand there in confusion as Miss Foster walked away and down the halls. He quickly snapped out of it though as he saw that the classroom door was unlocked, Miss Foster forgot to lock it... Alex scanned the hallway for any staff or students before sneaking into the room and closing the door behind himself silently. He headed straight towards Miss Foster's desk and found that she had left her computer logged in. A smile creeped onto his face as he sat down at her desk and began to search through her computer. He started with what his teacher already had open. It started with her timetable which showed Alex that she had just had a free period, it also allowed him to take a picture of it for his own use later on. He didn't spend long looking through her timetable before minimising the window and enlarging the next, and he was shocked. His teacher had been watching porn. He sat there stunned for a second before pushing it all aside with a devilish smirk. He was slightly impressed as she had made it quite far through the video and she also had multiple tabs open. He looked at what each one was and found one not to be porn but instead a different website which she had been reading a sex story on. He quickly skim read through the story and from what he gathered, the story was about a teacher and her student endulging in their forbidden desires. Alex began to smile before catching something in the corner of his eye. One of the drawers in Miss Foster's desk was cracked open. He reached over and pulled it open, his smile grew as he saw what was inside. It was a vibrator and it had clearly been used recently as he could see his teachers juices coating it. He picked it up and attempted to turn it on but it's batteries had ran out. Alex's dick was begging to be used by this point, the discoveries that Alex had made were overwhelming and he NEEDED a release. He swiftly removed his pants and underwear allowing his cock to escape and stand painfully erect. He began to slowly stroke the length of his shaft but as he did, he heard the door open and watched as Miss Foster stepped into the classroom and started to walking towards her desk. "Alex, what are you doing in here???" she asked. Alex didn't reply, instead he sat in silence with a devious smile on his face. Miss Foster slowly approached her desk and as she went to step behind it, she saw it all and was stunned. Her vibrator drawer was open, the sex story she had enjoyed earlier was on her computer screen and Alex was sat in her chair with his raging erection revealed. "A-Alex, what are you doing!?!?! You weren't supposed to see this..." she said with a shaky and fearful voice. "It's ok Miss" he replied "I like what I've seen so far and don't you want to indulge in your fantasy?". "Alex, we can't... It's... It's not right..." she shamefully admitted. "And?" He said as he stood up towering over her "It's fine as long as no one finds out". "No, we can't..." she replied. "Look how much you enjoyed reading about it though Miss" he said as he picked up her vibrator and pressed it against her lips "Don't you want to experience it in person?". She slowly opened her mouth and wrapped her lips around her vibrator as she nodded in response. "Well then, let's do it" He told her as he pushed her vibrator deeper into her mouth whilst she used her tongue to clean her juices off of it. She nodded again in response as Alex let go of the vibrator. "Sit down Miss" he ordered. She obediently listened and sat down in her chair before spreading her legs nervously. She then removed her shirt and lifted her skirt, Alex then helped her with the rest by unclasping her bra and pulling off her soaked panties. The sight of his nude and obedient teacher made Alex's cock pulsate in anticipation. She was already wet and Alex couldn't wait any longer. He pushed her further back into her chair and lifted her slightly before pushing his cock against her hole. Miss Foster released a muffled scream and her body tensed as she felt Alex's cock press against her hole. Alex began to try and penetrate her, Miss Foster gripped both of the chairs arm rests fiercely in response to the pain and discomfort. He kept going but struggled to get his cock inside of her. Miss Foster removed the vibrator from her mouth and exclaimed "THAT'S THE WRONG HOLE!!!!!" before bracing her body. Alex looked up at her with a smirk as he continued to push against her ass hole. Her body continued to tense up, but eventually, Alex managed to bypass her sphincter and enter her asshole bringing them both pleasure, pain and discomfort. He slowly continued to push his cock deeper into her ass as Miss Foster gasped, moaned and tensed. Her rectum squeezed Alex's cock tightly as she tensed granting Alex a lot of pleasure. Soon enough, Alex had inserted as much of his length as possible and stopped moving. Miss Foster quickly became confused and asked "Why did you stop?". He smirked at her before telling her to "Beg". Miss Foster hesitated for a moment, unsure on whether to obey Alex's request or not, but she did and reluctantly began to beg "Please Alex, fuck my ass". His smirk grew "More" he demanded. "Please, please... it's been so long since I've had a dick inside of me, please fuck me!!!". "More" he repeated. "PLEASE ALEX, PLEASE. I NEED THIS, FUCK ME IN THE ASS ALEX, PLEASE!!!!!" she begged. He chuckled before beginning to slowly thrust back and forth inside of her asshole. "Ow, fuck, YES, FUCK ME ALEX, ow" she pleaded followed by moans of pleasure and pain. Her rectum continued to squeeze his cock tightly as she continued to tense her body. "You're so tight Miss" Alex said. "YES I AM, NOW FUCK ME FASTER, PLEASE ALEX PLEASE!!!!!" she pleaded. "Ofcourse Miss" he replied before beginning to fuck her faster. His cock kept plunging deep into her ass and back at a rapid pace, it intensified the pain and pleasure for both participants and their climaxes began to build simultaneously. "yes, yes, yes, it feels so good!!!" she exclaimed. "Your ass... it's going to.... make me cum... " He said whilst breathing heavily. "Yes Alex, cum, CUM IN MY ASS!!!!!" she demanded. He pushed her further back in her chair and lifted her ass further into the air as he fucked her asshole vigorously. She continued to tense and moan, her rectum was extremely tight and was squeezing his cock. "I'm so close Miss..." Alex said. "ME TOO!!!" she exclaimed "DON'T STOP ALEX, PLEASE DON'T STOP!!!!! FILL MY ASS WITH YOUR CUM!!!!!!". She looked into his soul with pleading eyes as she bit down on her lip seductively which muffled her moans. Her walls clenched his cock as she begged for his cum and soon enough... they both exclaimed "I'M CUMMING!!!!!". They both released loud moans of pleasure as Miss Foster's juices began to swiftly pour out of her pussy whilst her rectum milked Alex's cock and he painted her walls with his cum. Their climax's last for a short while as they were both experiencing extreme levels of pleasure. Miss Foster juices wouldn't stop flowing and Alex couldn't stop releasing spurts of sperm deep into her rectum. By the eventual end of their climax's, they were exhausted and both froze for a few minutes as they tried to recover from their orgasms, however, they were cut short as someone began knocking on the classroom door...

Author's note: sorry for the wait, I have been struggling mentally recently and haven't felt like doing much. Also, sorry if this isn't as good as the other parts or if their are any inconsistency's with the story (I don't think there is but it's been a while since I wrote the last part so it's definitely possible).
