Ginny Weasley, the last child in Weasley family, the only daughter in the family, she is doted on by her parents and brothers. Although sometimes this caused her trouble, especially when she is secretly reading some books that she stole from her parents room.
She is always curious about this ever since she saw her parents having sex on bed. As she grow up her curiousity about this only increased. When she received her Hogwarts at age 16, which is the age every witch or wizard will receive their letter, she is ecstatic.
But soon found she can't use magic as she pleases. She needs to find a male friend in school that can help her purify her magic which has many harmful energies mixed in. Apparently this appeared nearly 3000 years ago when wizards fought against other races.
They won the battle but also got a curse from the combined might of other races. Their descendants will have their mana with impurities, when directly used this mana will cause them arousal in use and if you used it more often you'll be dead because of mana poisoning.
Wizards and witches did everything in their power to get rid of this curse but failed. Nothing worked, not even temporary solutions are there. The only known exception is if the wizard or witch possess an angel or fallen angel bloodline that can provide them with passive holy power to offset this curse.
But the last fallen angel descendant died 1000 years ago and since then this is seen as nothing more than a myth.
The purification process is to hold hands and circulate one's own mana into the other while the latter do the same. After both the mana get's mixed, it'll purify itself since the mana in a boy is completely opposite to mana in a girl. This purification needs to be done once every two weeks.
Of course if you use too frequently, this duration is irrelevant and purification needs to be done as soon as possible. Since the wizarding world cannot live without magic, wizards and witches started experiencing the arousal very regularly making sex a regular thing in their schedule. Restrictions of being a virgin is removed as a marriage conditions.
As Ginny Weasley entered Hogwarts, she dreamt off the boy who lived being her partner in purification of her mana. But sadly she got to know it's more complicated. They tested her mana compatability which is necessary for mana purification andshe got a boy from her own year. He goes by the name," Allen Shafiq ", a pureblood from Shafiq family and worse he is a Slytherin. Although hebis very good looking in Ginny's heart, Harry is the only one or she thought.
She gritted her teeth as she got no choice. Male count in wizarding world is in a serious decline afterall. In her year there are only 20 boys to 40 girls. She thought senior students will be here to make up the difference but instead every boy is assigned to two girls.
Luckily she didn't get another slytherin. Her friend Lunar Lovegood is also assigned to the same but as their mana also matched. But she observed Allen often talks to himself and curse while looking at nothing but empty in front of him. She thought her Hogwarts won't be peaceful.
When they did the ritual she felt butterflies in her stomach and her pussy suddenly feeling warm and weird. Luna is same, she has a dreamy look with a haze in her eyes. A lewd expression is formed on both the girls faces while Allen also has a blush as his dick stood erect.
Ginny is flabbergasted just looking at the size it reached almost 8 inches or more maybe. And it's thickness. Ginny gulped as she saw it's definitely reaching enough to break her completely. She used dildos from her mother's stash secretly afterall.
Luna on other hand is back to her normal look and said," that felt weird yet addicting ", Ginny blushed when Allen looked at them both back and forth. Every week they met to hold the mana purification ritual and each time this weird arousal between three of them became more and more evident.
Ginny is frustrated enough to use dildos everyday. And adding to that there is a weird dairy o a student named Tom Riddle that gives replies to what she wrote, so she shared her story to Tom Riddle although she left the parts where she acts like a dirty slut always trying to push dildos into her holes. Turns out it's this thing that is the reason for her recent blackouts. She is afraid and threw it away. But then she robbed it again from Harry Potter.
Then she lost consciousness once again. When she woke up though, she is in the arms of Allen. Her brother Ron and Harry are also there. After knowing the full story, she is scared. Allen and Harry fought against the basilisk to save her. She is grateful to them both but thinking about Allen even now she is feeling from her pussy.
One evening she finally confessed to Allen that she wants to have sex with him. Allen just smiled and said," then you have to agree to everything I'm going to do to your body and obey all of my orders. Think carefully ", she knew what he is asking and she read about those things in books from her parents room and also saw them doing those things.
After contemplating for two days she agreed finally and Allen asked her to come to an abandoned class room in seventh floor without wearing any underwear and in an old uniform with skirt. Although she wanted to refuse she agreed and even wrote a contract in magic. She got no choice. As she got there a hand wrapped around her mouth.
She wanted to scream but no sound is coming out. When she woke up to the lewd sounds. She saw Luna moaning like crazy. Her hands are tied behind her back, she is wearing a blindfold and she is completely naked. She is riding Allen's massive dick. Ginny wanted to strangle Allen but she soon find out she can't since her limbs are tightly bound. Her hands are tied both at the wrists and joints. Her legs are spread and she felt something. There is a buttplug inside her along with a dildo. She is almost naked with only her skirt on her body.
