Fleur was sitting in a chair in Dumbledore's office, with Gabrielle next to her. Dumbledore was sitting across from them. "Fleur, as a Vela you cannot be accepted into Hogwarts. It would cause, erm, problems." (I will not be do French accents) "Sir, there must be a way. Baubatouns has burnt down and I need a school. I will do anything" She started sobbing. Gabrielle started to comfort her, in the only way she could. Her hand slid up Fleur's skirt. Dumbledore was used to Vela be behavior,and he ignored this.
"Fleur, Gabrielle, there is one way. It requre you to give up your freedom, however." Fleur, who was now on her knees, naked form the waist down, and was being double fisted by her sister, was able to talk again.
"We will do it Professor. But only to Harry. I assume sex slavery." Dumbledore nodded. Gabrielle had stopped and both were sitting up again. Hearing this, she got scared. Seeing the head master nod, she peed her pants. Fleur was instantly on her knees, lapping it up. This was considered normal for Vela, and once again was ignored. Fleur took of Gabrielle's panties and put them up her own ass so her sister did not have to wear wet pantieses. "Call Harry, Dumbledore. Lets get this over with."
Harry walked in a few minutes later. He had Ginny and Hermione on leashes nex to him. The leashes lead to enchain that split in two and was connected to their nipples. They were both gagged and had 7 inch in diameter beads is their pussy and ass. It looked painful, but neither girls seemed to notice.
"Harry," Dumbledore said, "I will leave you to the ritual." Then, he left. Fleur and Gabrielle kmew the ritual. It was basic Vela training. The sisters began: "Nok de hiester, nal o dess" (Lord of masters, we undress" They then stripped naked, Fleur pulling the panties out of her ass. Harry continued, "Lo, kon i dipect" (I will inspect [the] slave) Harry waa now allowed to do anyting he wished, except enter them. He felt Fleur's E-cup breasts, squezing them. He then bent her over, intructing jer to stech her anus as much as she could. Fleur got to about 5 inches. He did the same with her pussy, this time getting to 10 inches. Harry moved on to Gabrielle. Her breasts we about DD-Cup. He did the same routine, but the younger Vela only got to 2 and 4 inches, respectivly. He then ordered Fleur to hold Gabrielle like a baby and breastfeed her. It took sometime, but Gabrielle managed to coax milk out of her sister's left nipple. Harry was ready to proceed. "Lo, reccp kon" (I accept [the] slave) Here came the best part for Harry. He needed to cum into their mouths, and get it going though their bloodstream.. He started with Fleur's mouth. She got on her knees and pulled Harry's throbbing cock from his pants. She sucked on the foot long rod, getting only a quarter of the way down. Harry sighed, magically removed her gag reflex, and foeced it all the way down. Gabrielle, never having been told to stop, had started suckling on her sisters right nipple. Fleur Gave Harry's cock a work out with her toungue. After a minute, he ejaculated for 45 seconds, almost fillimg the Vela's stomach. She then unleashed all of her milk into Gabrielle. Havimg completed this, Harry moved onto the youmger Vela He ordered Fleur to spank Gabrielle while she sucked him off. Ginny and Hermiome were released for their gags. Hermiome was made to eat out Fleur, while Ginny was made to spank her. This went on for 5 minutes, the cires of all females in the room ecoimg off the stone walls. Harry, having bomded both girls, fell to the floor, drained of power.
