Her twin brother (GryffinWhore for Slytherins)

Ivy thought of who could she truly, completely and utterly submit to, the thought of people like Draco Malfoy, her rival and how hot it would be, knelt next to him naked and A defeated look on her face as she’s paraded around Hogwarts. Then there is that student from Hufflepuff Zacharias Smith, supposedly an heir of Helga Hufflepuff, her treated as a pet, naked with a dog collar around her neck and a lead/leash connected to it. Being passed around by hooded **** Eaters, or even naked at the feet of her parents and Cedric’s murderer, naked chained to his throne and on her lower back, above her arse was the Dark Mark as a tramp stamp, showing she’d submitted to him a look of blissful defeat on her face. These thoughts were turning her on but then she thought of her twin brother.

Harry had been sorted into Slytherin, that was a big divider in their relationship, but not the only one. He was ambitious and strived to be the best he could be and wasn’t beyond deception to get there. She was sorted into Gryffindor and despite breaking so many rules she was not punished. Instead she was rewarded, yes she saved the school but she still disobeyed the staff. The rift started at a younger age all because she was older by a couple of minuets. Yes she flaunted that fact and it got even worse when they found out that as the oldest twin Ivy would have full control over the family vaults except Harrys’ trust vault which becomes his personal vault. Her mind slipped to envision Harry bending her over the desk and slapping her new fat derrière.

Ivy smacked her arse subconsciously and blushed at the little moan she released. She had an idea, it was hot, it was normally wrong but she could change it.

If the only members of a family left are twins then the younger twin can demand to contest the older twins eligibility,

i) Due to ancient law this can only be done through sex,

ii) The loser is the one who submits first,

iii) If the eldest twin loses then they will be stripped of their position and the youngest gains it.

Harry Potter is in charge whilst the Dursleys are out.

Harry James Potter has since the age of puberty had a 13 long inch penis when soft, when hard it increases to 16 inches long and 4 inches wide.

If Ivy Alice Potter ever willingly gets fucked by her brother she will break on his dick.

Ivy Alice Potter from that moment will never and absolutely can never refuse her twin brother.

When sexually dominated and/or broken the witches own magic will create a certain style of underwear,

i) If the witch in question is still in fact a dominant/Top afterwards then they get full cover panties, if they are a Switch then they get panties that show of their arsecheeks, if the are a Submissive/Bottom then they get Thongs, g-strings and other similar underwear.

Whenever a witch wears a thong or similar style of underwear she is signalling that she is at least a free use slut up to a whore,

i) There are special types of these underwear that have a crest of some kind signalling if they are owned,

ii) Ivy Potter will happily show off her thong when in the magical world, with the Potter family crest on show for all to see.

Ivy Alice Potter will be found masturbating and as punishment will be fucked.

Ivy couldn’t help it anymore, she shoved her hand down her panties to meet wetness, she looked and saw she’d soaked them. Her blush covered her body as she slipped two fingers in her twat. No mater how much she rubbed, fingered or just tried to get release it wouldn’t come. She looked to the door and bit her lip, she tore off her now unusable underwear grabbed a pillow and started humping it. Her eyes closed as her fantasy took over. She was riding Harrys’ knob, her breathing had increased with her arousal, here she was about to lose everything.

“Yes Harry please! Keep going I need it! Oh fuck yesssss, HARRY TAKE IT ALL FROM ME FUCK MY PUSSY INTO SUBMISSION PLEEEEEAAAAASSSSEEEE JJUUSSSTT OOOOWWWWNNNN MMMMMEEEEEEE!” She was so close to cumming, a few seconds more was all she needed, unfortunately for her she was stopped. Her hands were pulled out in front of her as she was pulled up and over the bed. the pillow with her juices all on it trapped under her cunt.

“I Harry James Potter do contest the eligibility of Ivy Alice Potter as Head of the House of Potter!” Harry says with a sneer. She feels her magic accept the challenge and moaned. She couldn’t move except to wriggle about, this did nothing more than show off her assets better. Ivy felt herself orgasm from getting spanked and soon she was panting. She felt his dick line up with her snatch and “tried”to desperately escape. She stopped as he pushed past her lips and started to fill her cunt with his member.

“FFFFUUUUUUCCCCKKKKKK!!!” she cried out as he started thrusting and she felt orgasm after orgasm from him fucking her. She looked back at him and saw his sneer and even knowing it was useless she gathered up all her hatred for him she had and looked into his eyes. “DO IT THEN, IF YOU THINK YOU CAN TAKE IT FROM ME JUST TRY IT” she felt him move his hands to her hips and flip her over before lifting her up and stopping. “WHAT ARE YOU DOING DON’T STOP” Ivy whined.

Harry turned so that he was sat on the chair and she was looking down at him. “Start bouncing or I sell your holes to Piers Polkiss and the other muggle filth” he spat at her and she did, just hearing him threaten that turned her on more. Soon she was willingly riding her twin brothers’ cock.

Ivy had felt it when Harry had claimed the Heir/Lordship from her. Her face had a constant fucked stupid look afterwards. Harry had after winning placed the top of his actual wand against her lower back and using a mirror had branded the word GryffinWhore as her Tramp stamp. He’d paid her a single Knut and laughed at her. She was now getting milked by Harry squeezing her udders.

“As you can now guess Ivy you’re a whore now, here is your thong.” Ivy looked at it and blushed. After telling him about the book he had her alter the size of her breasts, hips and arse. Now she looked like a Bimbo version of herself. Now she puts on the thong depicting a Snake subduing a Lioness with a 1X Bronze Knut at the top. “Well done Ivy, you’re the 1 Knut Bimbo GryffinWhore for Slytherin.”

Ivy had pictures taken and loved the attention of her superior sibling. A letter had come through the opened window from Gringotts to congratulate Harry on claiming Headship of his house. “Ivy” he called her name as she bounced her arse on his dick, “I know your so close to cumming so I thought I’d tell you that I sent letters to all Slytherins, they expect to see their GryffinWhore on the train”

“FFFUUUCCCKKK YYYEEESSSSSS” she cried out as she squirted her juices. The thought of Crabbe, Goyle, Nott and especially Malfoy using her body was arousing.

Where do we go from here?

1) Hogwarts Express. (Write suggestions for what she has to do for the Snakes, the reactions to her new life, how that makes her feel etc.

2) Harry takes her along to visit his fellow Slytherins.(“”)

3) Harry invites his friends around. (“”)
