Little Sister: Lilly's Corruption

Little Sister

An Erotic Story by H.G. Collins

---

This is an older story I recently updated. It was posted a few places after I stopped writing regularly for Lasiter on ASSTR and became a fan favorite among my work which was slowly getting darker at the time. In the past, I had a number of requests to make this into a longer series of stories. If there is enough interest, I might do that in the future. Enjoy! - H.G. Collins

“Anna, go get her.”

“No!” the girl whined again. “I’ll suck your cock really good. You won’t even need to hold my head when you cum this time.” The nine year old Anna stood defiantly in front of her father, unkempt brown hair strewn around her shoulders, wearing only a pair of red panties. It was a Saturday morning and as usual, her mother was out of the house.

“Go get her right now and bring her here,” her father responded sternly, pushing Anna in the direction of her little sister’s room. She could see that fighting it would be no use. Anna had been dreading this day, avoiding it for as long as she could. Whenever her father had mentioned breaking in her little sister, Lilly, she did everything she could to stop it.

Anna would start working hard to make her father happy and get him off before he could make a move on her younger sister. Just a week prior, she had forced herself to deep throat her father’s cock, nearly puking on her parent's bed. Anna hated it, but so far her efforts had kept her innocent little sister safe.

Of course, her father could have decided at any time to break in his youngest daughter and put an end to Anna’s hopeless plight. But he had enjoyed weeks of watching his nine year old willingly debase herself in order to stop him from defiling Lilly. Such a good big sister. But now, it was time.

Dejected, Anna made her way down the hallway and slowly pushed her little sister’s door open. “Hey, Daddy wants you,” she struggled to make out the words.

“Okay!” the five year old popped up and skipped down the hallway, unaware of anything out of the ordinary. Even Anna’s state of undress was quite normal around the house as both girls often sauntered around with little on in the early morning or evening before bedtime. Anna followed her younger sister apprehensively, dreading what her father would do with the girl.

"Good morning Lilly," their father said cheerfully. She replied, skipping up to the edge of the bed where fer father was sitting.

“Anna, why don’t you get started and take your sister’s clothes off?” He looked over at Anna whom had just walked in the room. Anna was hesitant, but she knew it was more of a command than a suggestion.

Her heart sank as she looked down at her little sister. It was bad enough that their father was going to have his way with Lilly, but forcing Anna to participate too made it so much worse.

“I’m not asking you again, young lady.”

With a sinking feeling of dread, Anna walked behind her sister, put a hand on either side of the girl’s shirt and began to pull it up.

“What are we doing, Daddy?” Lilly asked. Too young to think anything out of the ordinary, though, she lifted both arms, allowing her older sister to lift her shirt off effortlessly. Then, Anna’s attention then went to her pants, unbuttoning them and pulling them down as well. Their father admired Lilly’s much smaller frame. Her nipples were small and childlike, her body was shapeless unlike that of her older sister whom in a few short years would be filling out and growing tits. Their father was excited to start enjoying his youngest daughter’s body, too.

"Both of you go ahead and take your panties off too," their father insisted. "You girl's look so pretty when you're both naked."

"Daddy, what are we doing?" Lilly piped up again, suddenly aware that something was a little strange.

"No need to worry, sweetie, I think you'll like it," he responded slyly. Both girls removed their panties. He admired his two naked girls for a moment, comparing Lilly's pudgy nipples and childish frame to Anna's more defined, yet still child-like shape. He instructed Anna to lay down on the bed.

She was surprised at the instructions. She was sure that her father would be dying to get his hands all over her little sister and had been dreading having to watch it. But only making her little sister watch wouldn't be so bad, Anna thought as she took her place in the middle of her parent’s bed and spread her legs like usual.

“Alright, Lilly, now climb up here,” he helped the five year old onto the bed and set her next to her sister. Then, he took his usual position in between Anna's legs.

The nine year old relaxed and closed her eyes, preparing to feel her fathers rough facial hair rubbing against her sensitive skin or perhaps his cock pushing into her pussy. But she only felt his coarse hand resting on her thigh.

“Alright, Lilly, bend over and give her a lick right here,” he pointed to his eldest daughter’s pussy. Anna opened her eyes, realizing what was about to happen, and instinctively began to close her legs. But her father was ready for it, and held them open.

“Why?” Lilly asked.

"Because, I want you to. And it will make her feel good too."

"That's where her pee comes out!" Lilly complained, scrunching her face.

“Yep, it may seem a little weird, but you'll get used to it. You might even like it. Get your head down there and lick your sister up and down her pussy. This spot is going to feel the best though.” He spread open his daughter’s slit and showed Lilly Anna’s girlish clit. “If you do a good job and don’t stop until you give your sister an orgasm and she might be willing to return the favor.”

“What’s an orgasm?” the youngest girl asked. Instead of answering, he brought a hand to the back of the girl’s head and forced her head into her sister’s crotch.

Anna watched helplessly as her innocent little sister’s head descended on her pussy. She wanted to protest, but knew that if she did, her father would only make things worse. She wished she could take her little sister and run far away. Moments later, she felt the little girl's head in between her thighs and a tongue touched her soft flesh. Muffled noises came from the little one as their father gently held the youngest girl’s head in place. Tears began to well up in Anna’s eyes. She wished she could have done more to keep her safe.

“That’s it,” their father encouraged. “Get your tongue in there.” After a few moments, Lilly tried to pull away, but her father gently pushed her head back down and continued to encourage her.

As Anna felt her little sisters tongue swirling around her pussy, it didn't take long before she began to feel that familiar tingling sensation. But a wave of guilt accompanied it. She was actively enjoying her sister’s depravity and hated herself for it. Tears fell down the sides of her face.

As Lilly continued however, those feelings of guilt were steadily overwhelmed by pleasure. Anna let a soft moan escape her lips.

After a few minutes, Lilly was beginning to tire and tried several more times to lift her head from her sister's pussy. But their father continued urging her to continue, holding her head down when he needed to, and ignoring an occasional whine. Each time Lilly made a sound to complain, Anna could feel the vibration of her voice in her pussy. It was just another reminder that made her feel like she should have done more for her father so he didn’t start using Lilly, too.

“You’re not done,” Lilly he said forcing the five year old’s head back down to her older sister’s cunt. “I’ll tell you when you can stop.”

Meanwhile, Anna’s moans steadily became more frequent; until finally, her slightly less innocent little sister drove her over the edge. Anna’s hands grasped the bed sheets, feeling overwhelmed with pleasure and guilt. After a few more tired licks from Lilly, Anna's orgasm had subsided.

“Good job, Lilly,” their father complemented her once he allowed her face to ascended. “You just did a really good thing for your big sister. How was it?”

She gave a slight look of disgust, her face wet from her sister's pussy. “Why did you make me do that? It tasted gross!” The little five year old scolded her father,

“Yes, but you made your sister feel really good,” He looked at Anna. “Didn’t she sweetie.” Anna nodded, feeling guilty and wiping another tear from her cheek.

“Now, girls, go ahead and switch places.”

Anna and Lilly could tell their father wasn’t in a mood to argue, so they silently trades places. Without being told, Anna started to lower her head onto Lilly’s pussy, resolving that she would at least give her little sister an orgasm.

“Hold on, Anna,” Her father interrupted her. “If you want to lick your sister down there you can do that later. But right now, you’re just going to show Lilly how a man’s cock works. Go ahead and take my pants off so you can show her how to give a nice hand job.”

Feeling dejected once again, Anna shuffled closer to her father and started unbuckling his pants. Lilly had only seen her father naked once before on accident and lay there in shock and awe as her big sister stripped of his pants and underwear. He dispensed of his shirt by himself.

“Well, what are you waiting for?” Anna, swallowed hard, grasped her father’s cock, and began her task. Lilly watched her sister work his cock as she lay on the bed. Her eyes studied his cock in greater detail.

Lilly hadn't enjoyed eating her sister's pussy out at all, but watching her sister work their father's cock wasn't so bad. For a while, she stared at the funny shape of his cock, or watched her sister rhythmically rubbing it. But soon, she began to get distracted and stared off towards the ceiling.

While admiring his youngest daughter lying there, he reached out and began to rub the five year old’s chest. Lilly flinched at his touch, but didn’t try to move away. Their father instructed Anna to give his cock a few licks, too and show her little sister how much she could fit in her mouth. Feeling all the stimulation getting to him, he knew it was time.

“That’s enough for now, Anna,” He told his oldest daughter. Anna was shocked at the request since he hadn’t even cum yet and she felt a little relieved before he gave her further instructions.

“I want you to get behind your sister and hold her arms back,” Anna looked down at her clueless little sister as he said it.

“No, please just let me suck your cock!” Anna had been trying to be strong for her younger sister, but tears started to flow again. “I’ll do it really nice.”

“Get behind your sister and hold her arms behind her back,” He repeated sternly, giving Anna a look she had learned long ago not to cross.

Knowing it was no use, she climbed behind Lilly and lifted her off the bed slightly, grabbing both of the girls arms and holding them behind her back like she had been told.

Lilly was somewhat alarmed, but watching her older sister play with their father’s cock had been somewhat fascinating to the child and she was much more relaxed than she was when he made her lick her sister’s pussy. Her apprehension grew when her father climbed over her and began to kneel over her small body.

“Daddy, get off of me!” Lilly whined as she felt her father’s balls rub against her.

“Lilly, open up your mouth and just hold it open for me, okay?” he told her. At that moment, Anna could no longer hold back her tears, realizing the full gravity of what their father was about to do. Unlike her more experienced big sister, Lilly had no clue. She obeyed and opened her little mouth. Anna wanted nothing more than to stop and just let the whole thing be over with, but their father would never be satisfied with that.

Just like Anna had a few moments ago, he started jerking himself off, this time Lilly had a front-row seat, still watching in relative curiosity. Of course, she had never seen a cock up close before and admired the tip of her father’s which was pointed right in her direction. He let out a moan and inched a bit closer.

“Just keep that mouth open,” he said. A few stokes later, he began to cum.

Lilly let out a sound of confused shock when she felt the first stream of cum hit her face. Then a sound of disgust when she tasted it for the first time. The girl didn't have any time to react before more ropes of cum began to shoot at her face. She tried to close her mouth, but she struggled as she began to cry, feeling cum get into her eyes and start to sting. Lilly instinctively tried to lift up her hands, but Anna still held both harms tight behind her back. Meanwhile, more cum shot out, landing all over her face, in on her cheeks, and getting in her hair. The innocent child had been completely caught completely off guard by the sudden onslaught of cum. This made Anna feel even more guilty, wishing she could have let go of her little sister's arms and tried to shield her. Instead, she watched helplessly as the innocent girl gagged on cum and tried with little effort to move her head out of the way of their father's vile seed.

When her father’s orgasm finally subsided, Lilly’s face and chest was caked in cum and her eyes stung. She was whimpering softly as Anna began to speak sweetly and calm her sister down.

“That’s what happens when a man gets an orgasm,” he explained, wiping a bit of cum from her eyebrow. “You’ll get used to it. Won’t she Anna?” Anna wasn’t sure she was even used to it, but for her sister's sake, she agreed.

Their father disappeared for a moment into the bathroom, returning with a towel so Anna could wipe her sister’s face.

“I bet you'd feel better if you had an orgasm of your own," He half-hardheartedly consoled Lilly as Anna began to clean her up. "I bet your sister wouldn't mind licking you and giving you one if you asked. Anyways, I'm going to go grab some breakfast. You girls come out when you're ready. I'll make you both some pancakes.”

With that, he walked out of the room in a very good mood, leaving his two naked daughters on his bed.

"What is this stuff?" Lilly looked up at her big sister who was still trying to get cum out of the kindergartner's hair. She couldn't bring herself to answer.

"Are you going to lick me now?"

"We can maybe do it later, okay?"

"But I did it for you!" Lilly countered defiantly.

Unable to argue with the child, Anna relented and got into place.

She felt ashamed and guilty once again as she bent over her little sister's naked body. Reluctantly, she began to lick her pussy, knowing that everything had gone exactly how her father had intended. The older girl cried as she tongue fucked her five year old sister, listening to her soft coos and moans as the child felt feelings she had never felt before. As Anna began to drive her Lilly towards her very first orgasm, she also knew that it was far from over. Their father would have a great deal more in store for both of them.
