[Incest, Age Difference]

“Sis? What are you watching?”

It was an ordinary evening. An evening like any other. Or at least it was supposed to. But when a young boy, who didn’t know any better, heard loud sounds from his older sister’s room, his curiosity got the better of him. He was about to go to bed too, leaving him standing in the doorway with nothing but his cute childish boxers on.

He didn’t understand what was happening in front of him. His sister was sitting in her cushy chair, the same that she sat in every time she went on the computer and played all those games when she started swearing and used all sorts of hard words. It was so loud that his mom eventually forced her to get sound proofing, but he could still hear her late at night.

But what was she doing? She wasn’t gaming. She was looking at some sort of video. In the video, a big lady with a big hat and a very long white dress was pressing a boy down with her feet, and she was doing something to him. Why would a lady do something like that to a boy? And why wasn’t he trying to bite her to stop her?

“Ahaha… You wanna know what this is, lil’ bro?” His older sister, a beauty with short red hair and big tits that were barely kept hidden by the tube top she wore 24/7, grinned as she licked her lips a little. She had been wanting a little snack, and… Well, her brother would do the job quite nicely. Even if he wasn’t ripe yet.

He nodded as he closed the door behind him, his eyes transfixed on the screen and the way that the older and bigger woman kept pressing down against the boy. He didn’t understand why, but it was making him really hot…

“Mom never told you about porn, did she?” His older sister said, and he just tilted his head. The word itself had never crossed his mind, prompting his older sister to laugh in response. He was so pitifully naive. Not knowing anything about the world at large. It made it that much more alluring to corrupt him.

“Okay. Come over here, I’ll teach you.” She said, and her little brother approached. All while she spread her thighs, letting a bit of the juice from her hidden pussy pour down her meaty opening. “You see this, lil’ bro? This is what we call a Pussy. Mommy has one too, but hers hasn’t had fun in years.”

He looked into the strange underwear that his sister wore with all the holes that seemed kind of pointless, before looking down at his boxers. “I don’t have one of those…” He muttered, as he looked back at the lips hidden underneath that lacy fabric.

“That’s because boys have Dicks. Big, throbbing rods. Yours isn’t nearly as big as the ones I usually play with, but you’ll grow up sooner or later and then you’ll probably have one that’s as big as your fist. Dad’s was about that big.”

“Dad?” The little brother asked, tilting his head. He didn’t remember a Dad…

His older sister blinked, before laughing. Right. He had left her Mom because he slept around too much. Not that she was any better, that skank. And their daughter was just worse than both of them, considering what she had been up to.

“Why don’t you pull down your underwear, lil’ bro? We’ll watch a bit of Porn together, and then I’ll teach you what you’re supposed to do while you watch.” The older sister said, stretching a little as she patted her lap. Those fat thighs of hers could definitely support a boy his size. Even with the pounds he was putting on.

He quickly climbed into her lap and got comfortable, blinking as she let her huge boobs rest on his head. They were kind of heavy, but they were warm too. So he didn’t mind too much, especially as he looked straight ahead at that movie…

The woman in the movie had stopped squishing her foot up against that boy’s crotch, and had instead picked him up and let him rest in her arms. All while letting him suck on her boobies. A bit of milk started drooling down the boy’s cheek, just like when the little brother drank too much milk from his Mom…

The little brother watched carefully. Unaware of the hands carefully dancing their way down his body, causing him to tremble as they got closer and closer to his crotch. All while his breath grew hotter and hotter, his blush brightening as it crept across his face.

Until the obvious happened. His older sister, who kept on giggling the more she fondled his body without him noticing, grabbed ahold of both his underdeveloped sack and his pin-sized dick, causing him to let out a yelp in surprise as she started to play with both.

“This is what adults do when they’re having fun with Porn. They Masturbate.” She chimed, as she stroked her delicate fingers along that teeny tiny shaft. God, it was the tiniest thing she had played with… And she had been with a lot of young boys. The immorality of what she was doing only served to make her pussy leak even more.

Her little brother was letting out cute little impotent moans as he felt her fingers rubbing all over. And the visual on the screen wasn’t much better. It was of that big woman stroking away at a much larger thing than his. The boy on screen was so much more developed, despite looking his age. Was this what people liked..?

His sister was still watching, of course. There was no way that she would pass up the chance to teach him something that she had indulged in. “You like what you see, lil’ bro?” She asked, and she felt his head slowly nodding along her breasts. All while he kept moaning like the cute little thing he was. Slowly but surely being trained by her careful fingers.

Before he had a chance to experience his first tiny little climax, he found himself tossed and turned onto his back, now laying on his big sister’s lap with his eyes looking straight up at her boob. That big, milky boob. Was it milky? Actually, she was kinda bigger than mom now that he thought about it, so… She had to be milky, right?

The older sister hooked her finger onto her top and yanked it down, causing her tits to bounce wildly as her little brother’s eyes followed every little wobble. “Here, lil’ bro. Drink up. I know you want to.” She giggled, licking her lips as his mouth slowly but surely approached her nipple.

It looked really tasty. And it was definitely filled with milk. How could a little boy, who barely knew anything, resist the call of a tit like this? He almost immediately latched on once he got close enough, using his hands for a bit of support as he dug his cute little teeth into the tender flesh. Suckling and slurping away at it, licking and flicking the nipple to try and coax a bit of milk out of it. All while his adorable cock continued to throb as he awakened his youthful sexual urges…

His older sister just couldn’t help herself once she felt his adorable little mouth suckling away like his life depended on it. It was so, so cute. She could just gobble him up like those really weird videos she watched once. But no, she was going to give him the best orgasm of his life.

Which was why she snuck her fingers down beneath his cock. Beneath his nuts. If she was going to train her little brother, she would teach him the second best thing behind an orgasm.

Her little brother’s eyes widened as he sucked as hard as he could, because he felt something slipping in between his buttcheeks. It felt really weird. It felt super weird. And yet it made him thrust with his hips. What was going on? What was happening? Why did it feel s-soohhhhHHH

Just like that, the older sister smashed her middle finger against his weakest point. Underdeveloped, leaving it even more vulnerable than it would be in the future. And with that, his adorable face contorted into one of pure pleasure, as transparent cum splurted out from the tip of his tiny cock. It didn’t reach very far before it rained back down on his body, the poor boy popping off his older sister’s breast as he struggled to remain conscious after all that.

He snapped back awake after he felt the same powerful sensation rocking his body, prompting him to blush and moan as his prostate became a toy to his older sister. And he didn’t stop her. Because he kind of liked it, his cock throbbing wildly in anticipation…

Just like she had been trained in her youth, it was time for her to train him. Her fellow perverts would show him a good time once he was done being trained, so he could become a sex addict just like her...
