Chapter List
- 1-Coop x Millie
- 1
Millie Burtonburger turned 13 years old, growing up in a phrase where hormones were killing her childhood, she couldn't help but enjoy the presence around her older brother named Coop Burtonburger, who is only two years older than she is and she started to suffer some kind of love for her brother. But this was wrong... It was incest but at the same time, she couldn't help but have some sexual and romantic feelings for the only sibling she has.

One day, Millie was allowed to make an Instagram account on her phone, she decided to check out what her sweet sugar boo brother was up to, she opened his account from a different phone because his account was private on Instagram and she didn't like the idea that her own older brother would private his account. She managed to get in and saw a liberal amount of photos of Coop shirtless, in his swimming trunks, and more hot and arousing photos of her own brother.

Millie smiled at the photos of her brother, she slowly reached down to her bottom that was between her legs, she inserted her right hand inside her bottoms and she began rubbing her folds while she left out some moans. She reached for her vaginal opening, inserted her finger inside and she began masturbating for her brother.

Just when, Coop Burtonburger... The fifteen year old teenage boy walked in, noticing Millie was... Masturbating for something, he knocked on the door and Millie let go of her bottom, saying with annoyance and frustration "COOP! HAVE YOU-"

"I know what you're going to say!" Coop interrupted, his hands up in the air and he said "I came in to hear you moaning and I was thinking, what are you masturbating about?" Millie began blushing at her brother's presence, God he was so fucking hot and she couldn't handle hiding his feelings for him.

"Coop... I have something to tell you." Millie began saying with confidence "I have a crush on you, I love you more than a brother and I want you to be my boyfriend." When Coop heard those words, he felt disgusted and he wanted to vomit, he said "Millie! Are you insane!? We're siblings, biological brother and sister, blood-related siblings, we can't be together as boyfriend and girlfriend."

Suddenly, Burt Burtonburger walked in to see the whole thing, he asked his teenage son "What's wrong Coop?" The man in his forties asked his fifteen year old son, Coop pointed to Millie and began explaining everything to their single father "She has a crush on me! I'm her brother and I can't have anything sexual or romantic between her! She's my sister!"

"Coop... Whatever Millie feels is normal," Burt said, his arms crossed, defending Millie for her teenage phrase "She's going through puberty, or hormones to say the least and besides, how did you think humanity started?" Millie chuckled, adding "Daddy's right Coop, humanity started with incest, it's because there weren't many humans back then and siblings had to ride each other to keep the bloodline going. We didn't have to worry about inbreeding at all back then."

Coop couldn't believe what his father and sister were saying, this was completely wrong, he didn't want to be in an incest relationship with his own sister and he knew that this was wrong. "Dad? Millie? Are you insane!? I can't be in a relationship with my own sister!" Coop shouted, his fists clenched together like balls, Burt got angry and said "Okay! Millie, kiss your brother and let's see if he will change his mind."

"WHAT!? ARE YOU INSANE!?" Coop asked, nervous and shocked that his father, by blood would suggest something so sinister about this and hopefully, he doesn't-

Millie ran to her brother, grabbed his shoulders and pulled him closer to her lips, Coop tried to get away but after a few seconds, he suddenly embraced back and kissed his sister. Maybe being in a relationship with Millie isn't so bad at all and he couldn't wait for more time with her.

Burt watches, smiling that his own two children are now having a wonderful time, he said "Now I will leave you two alone for some private time, enjoy and remember to be careful." Burt said, he began walking away from Millie's bedroom and locked the door with his keys.

The two Burtonburgers pulled apart, Coop smirked and said "You're right Millie, thank you and I guess humanity did start with incest." Millie smiled, facing her brother's crotch and she grabbed hold of his pants, saying "Watch and learn about humanity."

Millie pulled out her brother's half-hard cock from his jeans, she began stroking his cock up and down, hearing him moan out her name and she began to plant a kiss on his sensitive cock head. She began sucking on his cock, going up and down, enjoying his tasty shaft and precum leaking out of his cock, she was enjoying her first blow job to her own brother and she couldn't believe how big his cock was.

Coop couldn't believe how good this feels, having his first blow job from someone like Millie, his own sister and her tongue was so sticky like bubblegum. Millie continued to blow him, she sucked harder until she felt his semen down her throat and she let go of his cock, strings of saliva connecting onto his penis.

"How does that feel?" Millie asked, she got up and began taking off her shirt, pants, and then her underwear, leaving only her bra on. Coop gave a thumbs up, Millie said to Coop "Lay down and I'll ride you." Coop nodded, Millie placed her foot on her brother's hips and she inserted her vaginal opening on his massive erection.

Millie moaned as her brother's shaft was getting sticky inside of her walls, Coop grabbed Millie's hips and pulled her down. Coop moved his hips up and down, making sure Millie was enjoying this and she grabbed hold of her brother's shoulders, clinging onto them.

The two moaned as their sexual way was on the floor, enjoying their incestuous encounter, Millie moved her hips and soon enough, she felt her brother's cum inside of her. She gasped louder, Coop did as well and the two let go of each other, they got up and kissed one more time.

Now they're together.
