A Daughter's Revenge

"Your son... just came inside you..." Lisa sensually whispered to the woman that happened to be her mother as well.

"Stop! I'm begging you... Leave Finn out of this. He's too young for any of this!" the naked woman gave it her all to convince her daughter to spare the boy, who had just came inside his own mother after fucking her in doggy style for almost 40 seconds.

"Mom... I'm sorry... I-" Finn was interrupted by Lisa who slid her fingers inside his mouth. The girl brought her face close to his.

"You see, my little stranger brother, you really don't have to apologize." the 20 year old girl started playing with his average penis. The boy's legs were shaking. "After all, it wasn't you who abandoned me at that dirty orphanage before I could even walk."

"LISA, IT'S NOT WHAT YOU THINK, WE CAN TALK THIS THROUGH.. PLEASE!" the mother yelled trying to untie her hands and cover her exposed pussy which was dripping with cum.

"My dear mother... you talk so much while your huge tits are in clear sight, it's funny... Also is it a bad moment to inform you that your son's cock just got hard in my hand?" Lisa said.

"Finn... I'm sorry..." the woman looked away horrified as she was unable to help her son in any way.

"I guess you really enjoyed fucking your mother, didn't you... Don't worry, I'll let you do it again" Lisa said and immediately got her mother's ass close to the boy's cock. "I didn't expect you to be this shy, bro. Don't tell me you are still a virgin..."

"DON'T!! PLEASE!! DON'T DO THIS!" she begged.

Lisa completely ignored her and started poking her butthole with Finn's cock, setting up the grand entrance. "Come on my dear brother, it's her ass you are going to fuck this time. Oh, and if you don't stop resisting it will be my finger going up your ass instead. I think you'd actually love it."

Finn's dick penetrated his mother's ass.

"AHHHH! OHH GOD! OH MY GOD!!" the poor woman screamed. Her son was struggling not to moan from the pleasure.

"Is it your first time mother? I wouldn't have taken you for an anal virgin. Guess your son isn't the only one to have bloomed today." Lisa said.

"Ah... Mphh.." the boy finally gave away a cute moan, action that made his sister very glad, giving her a perfect opportunity to make fun of him.

"Poor young man..." Lisa playfully teased him. "Having him do something so gross and immoral to his own mother..." the girl grabbed his butt cheek and gently started to caress it. "But you are already 18, you are a big boy... And I know what boys do when they are alone... In their bedroom..." she began playing with his butthole as she had earlier promised. "When nobody's watching..." she slowly inserted the tip of her finger inside his ass. "Isn't this what you wanted?"

"DON'T... PLEASE!..." Finn said louder than ever.

The girl got her mouth so close to his ear he could almost feel her tongue's touch. "Your dreams... are coming true!" Lisa said and instantly pushed her finger all the way up his ass.

"AHHHH! OHHHHHHHH!!" Finn yelled with every ounce of his being.

Lisa was moving her finger in and out of his asshole while the boy's dick was doing the same inside his mother's. Their movements were impressively synchronized.

"AHHH.. MPPPHHH.. AHHHHH.." the mother screamed again and again. "Please stop! Ple-ahh! Finn.. Ahhh! This can't be.. Ahh!"

Her son was obviously having the time of his life judging from his heavy breathing and the way his body was moving on it's own, guided by the pleasure. Lisa loved playing with the boy's insides, especially knowing how humiliating it was for him to be used and feminized in front of his own mother.

"Admit it, dude, you fucking love it, you love pounding your mother's ass like that, it feels good, doesn't it?" the girl started playing with the boy's nipples while still fingering him with her other hand. She was obviously getting insanely turned on. "You are so cute, my brother, I'll give you a taste of your beautiful big sis when we finish with your busty and voluptuous mum.

"You.. Ahh.. Fucking monster..! Ahhh!" the woman said roughly.

"Huh?" Lisa took her finger out of her brother's ass and walked in front of her mother, then stuck the finger inside her mouth. "Monster you say? Do you want to know what happened to me at that orphanage? Do you want to know what my birthday presents were? How all the boys bullied and beat me up like I was their toy, only for being pretty? You think the fact that you are tasting your son's ass will make up for that? Still think I'm the monster, do you?"

"Hmphh.. Ahh.. Whht.." the woman tried to reply. "Don't speak when your mouth is full, mother! At least that I was able to learn on my own." Lisa said and turned her attention to her brother. "Oh, you poor little thing! You want to cum so bad inside your mother, don't you? Here, let me give you a warmer place." the girl pushed her brother out of his mother's ass and in a flash took his dick inside her mouth.

"Ahh!! OHH!!" the boy moaned. Lisa started squeezing his butt cheek with her hand. "Oh your moans are so cute my baby, and you taste so good!" she took a break to say it and then started to suck again.

After a few seconds the girl got up and pulled the mother's hair, forcing her mouth on her ass. "Suck on that, bitch, I need my seat to please my butt, so I can then please your son properly. The woman licked her daughter's wet, peachy ass, crying her humiliation out.

"Ahh.. Ohh.. I.." the boy tried to scream but got interrupted by Lisa, who was now jerking him very fast with her hand. "Shhh! You don't need to say anything bro, just cum! Cum by the hand of your sister that you never knew you needed so much! Cum!" she started to kiss him aggressively with her sloppy tongue.

"AHHH!!!.. MMMMPHHHH!!!" the boy released his semen all over his sister and mother. Lisa got up and looked at the 2 of them, the eternal embarrassment was showing all over their faces. "Well, that was fun, my beloved family!" she said as she licked her brother's cum off her hand sensually.
