' Okay, I am intrigued. Be back in a few luv,' Harry kissed Hermione and squeezed her bum, then stepped out with Tracey . Tracey led him to a compartment where two other Slytherin girls were sitting , one of whom Harry recognised as Daphne Greengrass from his year. The other one was a third-year he vaguely recalled, but could not think of her name.

Daphne was a notoriously silent girl. She seldom spoke, and the rumour was that she was either terminally shy, or hated men . Harry doubted both theories, as she was aloof to girls and boys alike, and the few times he had seen her outside of the Great Hall or class, she was definitely not a wall flower. But Daphne tended to be easily overlooked in the overwhelming presence of Tracey .

Daphne was a cute girl, with long brown hair, and blue-gr e y eyes. The unknown girl looked a lot like a younger version of her, but had brown eyes, and looked to be more assertive.

None of the girls wore their school robes. Susan was again wearing a plaid skirt and a tightly buttoned up shirt, her breasts straining to pop out. Daphne was wearing a modest green vest and black ankle-length skirt, and the youngest girl was wearing a white T-shirt advertising the Holyhead Harpies, and was wearing tight blue jeans.

'Here he is girls,' Tracey smiled, and closed the door behind them, 'he was walking rounds with the Granger girl. I had to wait for him, but he Lovegood and Weasley girls kept me company, along with the new DADA professor.'

Harry waved a bit, 'Hi Daphne, hello girl-whose-name-I-don't-know.'

'Astoria Greengrass, at your service,' the young girl said, looking at him contemplative. 'Tracey, are you sure he can help us? I know he is Harry Potter, but –'

'Trust me girls, Harry will help. Won't you Harry?' Tracey smiled at him.

'I have to know what with first Tracey,' Harry smiled back at her.

'See? He won't help us,' Daphne said, frowning. 'This is a waste of time.'

'Not so fast girls,' Harry countered. 'What is it you want from me?'

'Harry, we need to ask you for a huge favour, but I promise it won't damage or hurt you in any way. You'll save two lives if you agree. But you must agree to it before you are told the details, okay?' Tracey begged him.

Harry scratched his chin, 'I don't know Tracey, I mean I want to trust you, but how do I know I can? I mean I know you're not one of Malfoy's goons, but I don't know you or Daphne that well, and this is the first time I've ever seen Astoria from close up.'

Tracey was still standing behind him, and suddenly he felt her hands on his bum. The Slytherin girlleant in, and whispered in his ear, 'please say yes Harry. I promise it is a good thing.'

Harry wavered, then steeled himself, 'what's in it for me?'

'Good, you are not that stupid,' Daphne nodded, 'I know you are Lord Potter and are richer than Croesus, so I won't offer you money. Instead I can give you Slytherin House.'

Harry sat down on the bench across from Astoria and Daphne, and leant forward, 'Okay, you've got my interest. I accept, I'll do you a favour in return for the unspecified reward. Now explain your last comment, Daphne.'

Daphne stared back, then had to look away with a blush, man that boy could stare a girl down... she took a moment to regain her breath, 'you probably think Draco controls our House? Well you're wrong. Draco is the decoy, the idiot we send out to make the others overlook the real Slytherins.'

Tracey had at some point taken off her robes, Harry saw in the corner of his eye. She was once dressed in an expensive looking silk shirt, and was wearing a long skirt that went down to her knees. Tracey sat behind direcrly Harry, and leant up to him, pressing her body against him.

'And who are these "real Slytherins" Daphne?' asked Harry, ignoring Tracey's hand, which had lited up his shirt, and slowly crept towards his crotch.

' Montague, Warrington, and our oldest sister Queenie aree the true leaders of the house,' Daphne calmly replied. 'Queenie graduated this year and the other two graduate next year, and your year is worthless, so I am being prepped to take over together with Urquhart and my cousin Vaisey. Astoria will take over once I graduate in turn .'

Tracey's hand was beginning to unbutton his pants, and Harry looked at her with a raised eyebrow. Tracey smiled, and continued her ministrations in plain sight of the other girls. None of them seemed bothered by it.

'Which brings us to the problem,' Daphne said in her calm voice. 'Daddy owns a majority stake in the business behind the Daily Prophet, Teen Witch Weekly, and most of the other periodicals in our world. Unfortunately he is also a compulsive gambler, and while he usually knows when to stop in time, he has gotten himself into huge problems with Mr Malfoy sr.. He had put the deed to the family business up for collateral, and lost, spectacularly. He owned 15'000 galleons in debt, and to get out of problem without giving up his business, he wrote up a contract for Astoria and myself that basically sold us away as chattel. Daddy cowardly did not inform us of this until we were on the train, so you can imagine it was quite a surprise when Malfoy was in here earlier to "sample the goods". I hexed him of course when he began feeling up Astoria, but with the contract he holds there is little I can do for the long term. He has told Astoria that he plans to take her as his trophy wife, whereas I will be given to Crabbe and/or Goyle for "fun". As you'll understand, that is unacceptable.'

Tracey had reached his cock, and was slowly stroking him. Harry found it harder and harder to concentrate on the conversation, but forced his attention to return. 'Okay, I see your problem. But what does this have to do with me?'

'You are the undisputed leader of our year,' Daphne said. 'You can get Draco into a Wizarding duel with the contract at stake, you can offer anything you like in return. Once you beat Draco you will own our contract, and thus own me, and the future of Slytherin House.' Daphne looked at Tracey's hand, 'take off his pants Trace, I want to see him for myself.'

'Now hang on,' protested Harry feebly, but Tracey took him in a kiss, and Astoria pulled down his pants and boxers, freeing his cock.

'Oh Morgana... he is an Adonis,' Astoria licked her lips, and Daphne looked on in unbridled lust as well. 'Anyway,' Daphne shook her head to steady her thoughts, 'you will take me as a Consort , and you can have Astoria as your betrothed for the future title of Lady Black . Our older sister Queenie is marrying a Muggleborn against my father's wishes and as such is no t eligible to inherit, so you can eventually get your hands on daddy's business, and his noble title. '

Astoria spoke up, 'I suggest you take me as your wife, the age difference will not matter in a few years, and that way Daphne here can be your Consort, and keep the Greengrass name. If you get her pregnant with a son and allow her to name him Greengrass, daddy can get an accident, and you will also be the acting Lord Greengrass until your son comes of age. I really hope you don't wish me to be your Consort instead, as I want to at least get my OWLs before I get pregnant,' Astoria smiled sweetly at Harry.

Tracey kept stroking his cock, and Harry was getting very horny. 'Okay, I can see the logic behind that. But why don't I just use the contract and take you both as my pets, and not take either of you as my wife?'

'You need to learn to listen Potter,' Daphne said calmly as if she was discussing school work . ' Marrying me or my sister will grant you access to the power behind the Prophet. I f you just take us as your slave or even just both as Consort, neither of us will be able to inherit it. Daddy's will is quite clear on that. The deed will go to the husband of one of his daughters, not to her owner or Consort.

' Since you insist on being stubborn , I'm giving you a free taste of what you can earn . Don't get your hopes up Potter, we will stay virgins until you show us the contract, but I think you earned some oral. You are in for a treat Potter, I've learned to give a blow-job in my first year as a way to get the then-leader of Slytherin House Marcus Flint under m ine and Queenie's spell, and I have gotten extremely skilled since. '

Daphne took off her clothes, folding them neatly on the bench. Astoria also stripped, but she was not as careful not to wrinkle her outfit. . The girls were very much alike, they had lithe bodies, with perfectly sized breasts – Daphne was 5'6, with perfect 34B breasts. He judged her weight to be around 118 pounds. She had a light fuzz around her pussy lips, but was otherwise nearly hairless.

Her younger sister had a 3 0A breast size, which looked larger on her smaller size of 5'4. He judged her weight at just short of 90 pounds. She had made the jump to a womanly body already, but still had something tomboyish about her somehow. She had no hair down below, but Harry could not judge if this was because she shaved or because her hair had not yet started growing.

Daphne moved to Harry and knelt before him, and licked his shaft from the bottom to the head. She then took the head in her mouth, and slowly started moving her head down further. Harry looked on in amazement as his cock went past her uvula, and he saw the bulge extend her throat. Daphne kept eye contact with him the entire time, and Harry reached down to brush some hair out of her face. Her right hand was under her, fucking her own pussy.

'Oh Morgana Daphne, that is so fucking hot,' said Astoria, as she began rubbing herself. Harry clearly saw her fingers spread her wet pink folds, as Astoria had her legs spread so he could perfectly see her virgin teen pussy. Daphne slowy raised her head again, making as much contact on his sensitive organ with her throat, mouth, and tongue as possible. She released his cock almost completely, until just the sensitive head was in her mouth, and she briefly tongued the slit on top.

Harry could not see Tracey any longer as she was behind him, but had a good idea what was going on as he heard her moan softly. Daphne winked at Harry, and took him down all the way again, a little faster. Then after she had him in her throat as long as she could manage, she let him out again, and teased him with her tongue once more. Harry felt his balls start to clench, 'Daphne... I'm about to cum,' he warned her, and Daphne closed her lips around him in again. Harry shot his load in her mouth, and Daphne sucked everything in her mouth, not swallowing. She finally released his cock, closing her lips around her bulging cheeks tightly. She had not spilled a single drop.

'Daphne? Can I have some?' Astoria asked with a curious voice, and her sister stood up, walked over to her. Daphne pressed her lips around Astoria's, and Harry looked on in awe as the two sisters swapped his cum back and forth, before they swallowed. His cock began to grow hard again.

'Yummy Harry,' Astoria smiled at the older wizard with a blush, 'so that's what it tastes like. I can't wait to drink it from the tap.'

'That is all you're getting until you get our contract,' Daphne added, a blush on her face, 'but if you need some help with that hard cock, I think Tracey is eager?'

Harry faced the third girl. 'Tracey, you up for it?'

'Shove that hot rod up my cunt Harry!' Tracey yelled at him. She was lying on her back, kneading her breast with one hand and pushing three fingers in and out her sloppy hole

'As my lady wishes,' Harry grinned, and guided his cock in Tracey 's willing entrance. The blonde whimpered a bit as Harry pushed in, but egged him on with a whispered 'keep going'. At her request Harry went deeper, and as Tracey pushed back against him , Harry bottomed out in her. He began a fast rhythm of pounding in and out of her .

'Oh fuck me Potter, fuck me hard you Gryffindor bastard,' Tracey shouted , and then she racked her nails over his back. At the sudden pain Harry tensed up, and shot his load up Tracey 's tunnel with five big splurts. ' Oh fuck you're fucking coming inside me ,' Tracey cried out as she came, her pussy milking Harry dry.

Drained, Harry rolled off her. Tracey was lying there quivering, but when her orgasm passed she beckoned Harry over, and cleaned him off with her mouth. After a while more, Harry got dressed again. He looked back at the Slytherins, and saw both were dressed again. Astoria was still flustered, but Daphhe had her signature calm look again.

'So how did this,' Harry indicated the naked and sweaty Tracey, a pool of his cum leaking out of her abused cunt, 'come to pass?'

Daphne grinned, 'Tracey is a my pet, no other way to say it. I saved her life before Hogwarts even started, she had stepped out on a Muggle road and was about to be ran over by one of their horseless carriages. I jumped against her, sending us both out of the carriage's way, and saving her life. When I wanted some girl sex in my second year Tracey was all too eager to help, and I somehow triggered a slave bond with her. Show him your collar dear.' Tracey blushed, and a leather collar much like Ginny's, but bearing the Greengrass 'G', was on her neck as a choker.

Daphne is sneaky and smart, but far too bossy for me , Harry thought. I think I'll bind them all to me, that'll calm her down. Won't she be surprised if she finds I already have a fiancée for one House, and two Consorts?

'One last question, and Daphne, let her answer. Astoria, are you okay with all this?'

Astoria blushed and looked down, unable to keep his gaze. 'Yes Harry. I think you're really hot, and would love to have you be all my firsts, if you will have me.'

Harry smiled at her, and caught her eye. 'Okay then Daphne, Astoria, I will challenge Draco for your contract.' He stood up, and spanked Tracey's arse. 'Trace, thanks, that was a fun ride. If you ever want another round, just let me know.'

A happily whistling Harry went back to his own compartment. On the way he passed a compartment from which he heard soft moans, and peeked inside. Ron Weasley had Lavender Brown on his lap, her shirt was off, and the freckled boy was snogging the girl heavily, while his one hand was cupping her breast over her bra, and the other was on her bum. Good on you mate, Harry thought, walking on.
