Definitely Not Good

I don't own 'Harry Potter'

Warning: genderbend character (Harry); dark fem!Harry; femslash

Ianthe wasn't a good person.

A good person wouldn't have decided everyone in their society could go and fuck themselves before leaving them to their own self-destructive devices.

A good person wouldn't have eagerly delved into the horrific and forbidden magics of the Black family with gleeful abandon, happily shredding every inch of their stifling and sickening Gryffindor mask as they did so.

A good person wouldn't have casually kidnapped half a dozen people to be used in a ritual that would be fatal to them without batting an eyelash at their pain-filled screams.

A good person would never have embraced the darkest aspects of their person so openly without feeling an ounce of regret for their actions, but she was not a good person. She could almost imagine seeing the horrified look in Dumbledore's blue eyes, no longer twinkling in amusement, rather condemning her as evil as they passed hypocritical judgement.

People were a product of their environment after all, and Albus Dumbledore had gotten his little martyr without realising the consequences.

She was never going to be a perfect little hero while growing up having to survive each and every day, and she giggled at how Dumbledore had inadvertently turned her into Tom 2.0 when he was really trying to avoid that exact scenario.

He was an imbecile.

Ianthe Potter wasn't a good person, hence why she had no qualms murdering people just for the chance to go back in time and have some fun.

After all, the possibilities of before were endless.

Ianthe Peverell looked around the Slytherin common room and smirked at how her peers tried ever-so-subtly to catch her attention and favour. She was the Queen of Slytherin, a girl that was Head of her own family, and all her fans were essentially tripping over themselves to be the one she gave her attention to.

Being a Parselmouth in Slytherin House was like being royalty.

Though she did wonder if anyone would be truly happy with her if they learnt about her 'extra-curricular' activities. Killing people so arbitrarily had never sat well with many, and the fact that she'd happily taken out more than a couple dozen adult magicals probably wouldn't go down well with whoever she'd be with.

"Ianthe."

Except her.

Ianthe turned to see her Housemate of seven years and had to concede the Black family were breathtakingly gorgeous. Long black curls were currently pinned back to the crown of her head with a few cascading down to frame her face, silver eyes with thick black lashes surrounding them, and flawless ivory skin she just wanted to run her fingers over.

Yes, Bellatrix Black was beautiful.

She was also startlingly sane considering her future self, but perhaps that had something to do with her insane parents and Walburga Black being amongst Ianthe's list of victims.

It was such a shame the Black family suffered such a terrible duelling accident. On an unrelated note, Ianthe Peverell was a fantastic contribution to the field of ritual research.

"Hello, Bellatrix. You're looking lovely as ever."

The barest hint of red crept over the other girl's face and she looked so lovely that Ianthe decided then and there that Bellatrix would be hers.

Bellatrix was a Black with a penchant for dark magic, she wasn't loudly proclaiming her allegiance to a Dark Lord that no longer existed – Goblins were so helpful when it came to soul magic – and she was incredibly intelligent. She was intriguing, and Ianthe was tempted beyond words.

There was also a part of Ianthe that was still as headstrong as ever.

"Bellatrix, did you want to see that book I told you about?"

Leading the subtly-confused silver-eyed girl through the room and towards the dormitories, Ianthe couldn't help but be incredibly grateful that Slytherins had their own rooms. There was no way this encounter was for anyone's eyes but their own.

As soon as the two seventh-years were in Ianthe's room, she silently warded the room before grabbing Bellatrix and pushing her against the wall none too gently, leaning up on tiptoes to shove her tongue into the taller girl's mouth.

She felt nothing but excitement and smug pride at the sound of Bellatrix's moans. Her tongue tasted every inch of the Black's mouth, lips pressing hard into the other set almost as a mark of ownership. Ianthe had one hand curled possessively around Bellatrix's neck, her thumb pressed just a little too hard for comfort into the front of the throat, while the other was fisted tightly in riotous black curls holding the two bodies close.

Ianthe pulled back, smirking at the sight of a red face and laboured breathing. This was the sort of fun she wanted, and she'd be keeping it if she had her way.

"You're mine."

Bellatrix nodded rapidly, grey eyes alight with glee. "Yours."

Ianthe's lips quirked in a sly grin. She'd basically just won. Now all she had to do was explain her proclivities to her fellow snake and get in contact with Lord Black.

But first … Well, the body in front of her left much to be explored.

A/N: Hey guys!

I see a lot of dark Harry fics, but not any fem Harry versions. Does anyone have any recommendations?

I'd like to thank GinnyLover14 for giving me the inspiration for this one. They said they've never seen a fem Harry/Bellatrix before, so I was wondering if anyone else has. I know I haven't.

Hope you guys liked it, and I'll see you next time!
