The Younger Sister

Twenty-five year old Harry Potter had just sat down after a long day of work and poured himself a glass of Ogden’s Finest when he received an urgent message through the Floo.

This was fairly common in his line of work. After defeating Voldemort, the Auror Department practically begged him to join up. Since he had already planned on it, he did so with happiness. Even though the training program was long and difficult, he persisted and tried his hardest. After three months of grueling training, he finally graduated to the lowest rank of Aurors. He didn’t mind. Everyone started out the same way. After another three months, he ranked up again and was no longer on probation. Since then, he slowly worked his way up until he was made Head Auror at twenty-four.

His promotion rankled some feathers, but no one could honestly say that he didn’t deserve it. He always got the job done and knew how to play politics. This was thanks to his friendship with Daphne Greengrass. She too worked at the ministry but had aspirations to reach the very top. She wanted to be the Minister of Magic one day. Since Harry wouldn’t touch that position with a ten-foot pole, it made sense for them to form an alliance. He would help her rise to her desired position, and she would help him. So far, things had worked out well for them both.

That’s why when Harry received an urgent Floo-call, it wasn’t out of the ordinary. He was often pulled into work at strange hours. Usually, it was because some heir to some important house got busted doing something stupid. This time, it was something a bit stranger than that.

Narcissa had called him with an emergency. She wouldn’t say what, but he knew that she wouldn’t call without a valid reason. Narcissa wasn’t the type to panic unnecessarily.

Harry had also built a strange rapport with Narciss Malfoy. Her husband Lucius was killed during the final battle, and her son, Draco was seriously injured. Harry wasn’t sure where she kept Draco, but it wasn’t anywhere in the country. Rumors were that he was getting secret treatments somewhere abroad. From what Harry remembered, Malfoy was in really bad condition. He couldn’t walk and could barely move his arms. That’s what happens when a Giant steps on your spine, Harry guessed. It was ironic that the Giants were supposed to be on Voldemort’s side, and they ended up killing and injuring more of his followers than his enemies.

After Lucius was buried and Draco was shipped off, Narcissa had the unenviable task of trying to fix her family’s reputation. For a while there, no one wanted to have anything to do with her. Those who opposed Voldemort were angry at her for obvious reasons, and those who supported Voldemort were trying to fix their own reputations. They didn’t need someone else making their jobs harder. In the pureblood-supremacist community, it was every man, woman, and child for themselves.

Because Lucius and Draco were now out of the picture, she had complete access to the rest of the Malfoy fortune. While it was true that Voldemort had drained their bank account significantly, there was still plenty there. That’s how she got involved with Harry.

Harry’s bank account was decent enough. He had enough to last him a while if he spent conservatively. Narcissa, however, offered him a great deal of gold if he helped her get out of the gutter and back into the good graces of the magical community. At first, he outright refused, but after talking to her and finding out that she really wasn’t that bad, he agreed. The money was simply too good to pass up, and if she screwed up again, he would make sure that no one would ever speak to her again.

With Harry’s reputation, it was easy to get her back into civilized society. In fact, there were even rumors that they were secret lovers. This happened to be true. While Narcissa was older than him, she was still quite the looker. She was no longer married and had little desire to be courted by some old, ugly pureblood looking for a sweet piece of ass. As such, she seduced Harry and talked him into a friends-with-benefits kind of deal. The arrangement worked out well for both of them.

Harry set his drink down and walked over to the fireplace. Tossing some floo powder in, he watched as the orange flames turned emerald green. He stepped into the green fire and called out, “Malfoy Manor.”

He stepped out of her fireplace only a moment later and waved his wand to remove the ash from his clothes. Looking around, he saw Narcissa walking up to him. Kissing both of his cheeks, she grabbed his hand and began pulling him somewhere.

“Would you mind explaining what is going on?” Harry asked the sexy blonde.

“It’s my sister,” Narcissa told him, pulling him up the stairs.

“Andromeda?” Harry asked. As far as he knew, neither of them was too fond of the other.

“No … Bellatrix,” she confessed.

“Bellatrix?” Harry asked, confused. “She died during the final battle,” Harry said. He watched as she took a curse in the chest. He wasn’t sure what curse hit her, but she went down like a sack of dirt and didn’t move. She was still laying there with her eyes open hours later when he walked the killing field. He just assumed that she had been killed. Narcissa shook her head.

“She was severely injured. The curse messed up her insides quite badly. I collected her body along with my husband and son’s thinking that she was dead. I later found out that she was barely alive,” she confessed, not looking at him.

“I’ve had a private Healer looking after her, trying to get her back to normal.”

“Narcissa, if she’s alive then she’s a wanted criminal!” Harry rebuked the woman.

“I know! But she’s my sister,” she looked back, pleading with him. Harry sighed.

“If people find out, you’ll be dragged into the street and stoned,” Harry shook his head.

“I know. That’s why I came up with a plan. It just didn’t turn out quite right,” she said, leading him to a locked door. She tapped her wand against it and opened it up. Harry walked inside to see a young and very sexy Bellatrix unconscious on the bed. Her long, dark hair was a bit scraggly and unkempt, but it added to her sexiness. Harry walked up to her and began waving his wand. He wasn’t an expert Healer by any means, but being an Auror, he needed to know the fundamentals in case he needed to quickly patch himself up.

“What happened to her?” Harry asked Narcissa while trying to decipher the readings that his spell was sending back.

“As you know, my family practically brainwashed her in her youth, and she was never very strong-willed, to begin with. Then, after spending so long around the Dementors in Azkaban … Well, her already shaky mind seems to have broken. You remember what she was like after escaping?”

Harry remembered the baby-talk and insane cackles. “And her youth?”

Narcissa blushed heavily. “I hired a very talented Potions Master to develop a tonic that will keep me looking young. He made one even better. I can actually look younger now!” she said with excitement. She then looked at Bellatrix with envy.

“I had planned to smuggle Bellatrix out of the country, but I couldn’t let her go with a broken mind. That would be really bad for everyone. I hired a Mind Healer to fix what he could, then he erased the memories of the last several decades. Bella thinks that she’s only a few years out of Hogwarts. As for her youth, she’s still the same age. She just looks younger,” Narcissa explained to him. “I went a bit overboard with the tonic. I had planned on making her look young and dyeing her hair before sending her to live abroad.”

Harry shook his head. He suspected that Narcissa used her as a bit of a guinea pig to test the limits of the youth tonic. He didn’t bother bringing that up.

“So what’s the problem?”

“The tonic seems to stimulate the body and cause certain urges to form. It’s not very noticeable when taken in moderate quantities. But ... “

“When taken in excess, you become super horny?” Harry smirked. He could smell Bellatrix’s arousal the moment he walked through the door. Narcissa nodded.

“What did the Healer say?” Harry asked.

“She needs to be overstimulated so her body can burn through the potion. Then she’ll still look young, but won’t suffer through the side effects,” Narcissa looked at him, blushing. She didn’t tell him that she planned on taking a healthy dose at some point.

“Overstimulated?” Harry raised an eyebrow.

With pink cheeks, Narcissa nodded. “It will need to be both of us. That’s why I came to you … for obvious reasons.” Harry sighed and nodded. He couldn’t believe that he was going to let Bellatrix go. Though he’d tag her and make sure that she never harmed anyone again. Harry stripped down until he was completely nude and watched as Narcissa did the same.

They crawled onto the bed, and Narcissa pulled Bella’s bedsheet down. Instantly, he was hit in the face with the intense smell of arousal. Bella’s pussy was dripping wet. Narcissa waved her wand, and Harry watched as her eyes fluttered open. Seeing two nude bodies, Bella didn’t even say anything. She just grabbed Harry by the back of his neck and pulled him down for a kiss. Harry’s eyes widened at the intensity of her kiss. She was trying to suck the tongue from his mouth as she maneuvered him between her legs. Harry moaned as she rubbed her soaking wet pussy all over his massive erection.

“She needs it badly, Harry. Give it to her hard!” Narcissa told him while reaching between them. She grabbed his hard, throbbing cock and placed the tip against Bella’s opening. She felt Harry push forward, and his cock slid through her closed hand as he penetrated her sister. Narcissa then broke their kiss and leaned down between them, taking Bella’s hard nipple into her mouth. She softly bit down on the hard nub while she moved her hand to the point of their connection. Her hand slid down Bella’s sweaty belly and over her incredibly smooth mound until her fingers found the engorged nub that she was looking for. Flicking her fingers over it rapidly, she heard Bella moan loudly as her hands groped at Narcissa’s nude body.

As Narcissa let her tongue wiggle around the crinkled nipple in her mouth, she used her fingers to rub and roll Bella’s damp clit while Harry fucked her harder and harder. Bella was breathing heavily and suddenly screamed. Hearing Harry moan, Narcissa knew that she had just came. The wet squelching of her pussy had gotten louder from the sudden tightness of her contracting walls. Harry pushed her knees up into a mating press and came deep inside of her. Narcissa watched as he pulled his massive cock out of her. His long, thick cock was literally dripping with Bella’s juices. Narcissa had never heard of a pussy being so wet.

“Switch,” Harry said. Narcissa watched as he straddled Bella’s chest and shoved his dripping cock into her mouth. Bella gladly took him down her throat. Narcissa watched in amazement as Harry began to thrust, and he actually started fucking her mouth. Narcissa crawled between her sister’s splayed legs and found her pretty, little pussy all pink and violated. It was leaking Harry’s cum from between her plump and tight lips. She saw a streak of white leading down to Bella’s asshole. Leaning down, Narcissa placed her tongue against her sister’s asshole and licked her all the way up to her clit. She didn’t stop licking until Bella’s pussy was shiny and clean. She then used her fingers to spread her tight lips open and revealed the lovely shade of pink underneath. She stopped for a moment when she realized that her pussy was nearly identical. Shaking her head at the thought, she lowered her head and stuck her tongue inside of Bella’s hole.

Harry looked down at the crazy lady who had fought so hard against him. If she had only known that years later she would be taking his cock down her throat, he thought amusedly. He had to admit that Bella was incredibly gorgeous in her youth. Her skin was smooth and creamy with just a bit of a tan. Her breasts were perky C-cups that were capped with large nipples. Her legs were long and sexy, and she had a wonderful hourglass figure. Her pussy was absolutely fantastic, Harry thought. It was perfectly smooth and incredibly tight. She had made him cum faster than he had in a very long time. She looked up at him with pure desire as his cock pistoned in and out of her mouth. Pulling out, she gasped and breathed in and out heavily. Looking back, he could see Narcissa wiggling her tongue against Bella’s hard, throbbing clit. Getting up, he moved around behind them.

Narcissa squealed when he gave her ass a hard smack. She moved out of the way for him. Not so gently, he flipped Bella over and lifted up her ass. Narcissa helped him by spreading her cheeks. She placed her finger against Bella’s naughty hole and began to massage it.

“Would you like it in the ass, Bella?” Harry asked in his deep voice.

“Merlin, YES!” she gasped, gripping the sheets tightly. Narcissa grabbed his cock and held the tip against her hole. Grabbing her wand, she coated his cock in lubricant and used her hand to rub it in as he slowly worked his way into her. Reaching underneath Bella, Narcissa placed her fingers against her clit and started massaging the sensitive nub. Bella’s back arched as Narcissa watched Harry’s cock sink deeper into her. She could hear the pained noises coming from her sister, and she could relate. She remembered the first time that she took Harry’s cock into her ass. The stretching sensation was insane. Still, it seemed that Bella loved it. She was actually moving her ass back to take him in faster. A hard slap on the ass made Bella squeal, and Narcissa noticed that her pussy began to drip. Perhaps she liked a bit of pain, Narcissa wondered.

Harry pulled out until only the head was in. Narcissa re-lubed his cock before he pushed back in. This time, he penetrated her faster than before. Narcissa had a front-row seat as Bella’s ass began getting destroyed by Harry’s thrusting beast. She made sure to keep her hole nice and lubed as his cock continuously speared her opening. Both of them were moaning loudly and Bella was starting to shake. Dipping her head underneath her, Narcissa sucked her clit into her mouth and began massaging it with her warm, wet tongue.

Bella bit down on the bedsheets and cried out, clenching her ass as she experienced the biggest orgasm of her life. She felt the mystery man spurt cum deep into her asshole as Bella’s body quivered in pleasure. Suddenly feeling lightheaded, Bella fell on her side and blacked out. As she did, Harry’s cock was pulled free. Harry and Narcissa watched as Bella rolled on her back with her legs spread wide. He could see her pussy contracting even though there wasn’t a cock inside. He reached down and poked at her clit. Bella’s back arched, and she cried out. Pussy juice began to spray from her tight hole and misted Harry that was standing in her way. Looking at Narcissa, he smirked.

“Looks like you aren’t the only Black sister to squirt.” Narcissa blushed heavily and slapped his shoulder. Without another word, Harry grabbed her by the ass and lifted her up. They shared a passionate kiss as he laid her down on the bed. Over the next hour, they fucked in every position as she was splayed over Bella’s unconscious form.
