An owl was resting on the fence of Heathgate Street in northwest London. It has just delivered a letter addressed to Hermione Jean Granger. The letter was written by professor Albus Percival Wulfric Brian Dumbledore, the headmaster of Hogwarts school of witchcraft and wizardry. Hermione quickly read the letter but it didn't make much sense to her. She never heard of Hogwarts let alone applied for it. Last few months were very strange for her. Sometimes she could move light objects or even close the door with her thoughts. She also noticed few hairs in her private area and decided to shave them.
Curiosity drove her to read everything there is to know about puberty and soon she discovered sex and with that, masturbation. Even though she had no interest in boys yet, she loved pleasuring herself every evening before sleep. First she force her index finger and middle finger down her throat (she could get them both fully in her mouth with little to no gagging by now) to get them nice and wet. She spat on her left hand and got her clitoris sogging wet. She then proceeded to put her right hand fingers into her needy little pussy. When feeling brave, she sometimes tried to put as many fingers as she could inside her. Sadly she couldn't fit more than three yet but she promised herself that in the upcoming year she will train herself to maybe even take on a fist. "How will I get a dick in there if I can barely fit three fingers?" she often said to herself "I need to stretch it a bit".

Hermione showed the Hogwarts letter to her parents with hope they knew what this school was all about. Sadly they also haven't heard of Hogwarts. They decided to write back so they could get some more information. By the end of summer vacation she knew everything about Hogwarts. She read quite some books about it. She also learnt a few basic spells. One particularly useful was vibrationis which made her wand vibrate. The orgasms with it were amazing but it was kind of hard to stop the wand because counter spell required correct hand movement which wasn't easy while the bloody stick was vibrating all over the place.

On the first of September she boarded Hogwarts express. To make the trip even more interesting she inserted a ping pong ball beforehand. It took quite some time and effort to get it in not to mention some pain from her tight hole stretching, but once in, it felt amazing and Hermione was proud about her achievement. She decided to sit with Ronald Weasley and Harry Potter because it was the least crowded coupe in the train. Two boys were friendly but they didn't even read the school books let alone learnt them like she did.

When they arrived at their destination Hermione was blown away by the shire scale of the castle. But what really intrigued her was the biggest man she ever saw. »Oh my god his dick must be huge« she thought to herself. He introduced himself as Hagrid the gatekeeper of Hogwarts. Only first graders went to the castle with boats. Hermione was glad that some water from the lake occasionally splashed into the boat so she could have an excuse why is she so wet. She couldn't stop imagining Hagrid's huge cock plowing her tight virgin cunt, and the pingpong ball inside her didn't help the matters either.
Her thoughts were interrupted by tall strict looking women. Professor McGonagall lead them to the great hall where the sorting had would choose their house. She was hoping she would get into Hufflepuff or Gryffindor. But before that, headmaster gave them some rules of where not to be if they don't want a painful death. Professor McGonagall looked at the parchment and Hermione was the first to be sorted.
»Relax« she said to herself while she slowly walked to the sorting hat. »Hmm very hard working this one, yes. But also really horny, even at such a young age. Hufflepuffs are too strict and don't approve dirty thoughts you know young girl. So I have no choice but to put you in GRYFFINDOR!« it screamed.
Hermione panicked thinking that the others heard what the hat was saying but it seemed like the crowd only heard where she has been sorted and not the reasoning behind it. She let out a sight of relief and walked over to Gryffindor table. With every step she felt the ping pong ball which was buried deep inside her. The pain of having it stuck there for a few hours and the thoughts of Hagrid's penis turned her on. She couldn't wait to get some alone time.
