Chapter 7: Sister's headquarters
The next day, Alex woke up refreshed. He cleaned his room, took a shower and went down to the kitchen, finding his mother. He walked up behind her and gave her a hug.
"Good morning mom. Thank you for yesterday, that was really good."
Mary, who heard the footsteps coming, turned around just before receiving the hug.
"Oh, honey. No problem, it was also very good for me. And you know that in the future it will be a daily thing, right?"
Even though his mother was clean, Alex felt the breath of cum coming from his mother's mouth.
"Of course mom." Alex gave a dazzling smile.
"Excellent." Mary says this while picking up a large glass with white contents.
Looking at this, Alex asks.
"Is this…Jason's cum?"
Mary smiles. "Yes, that's the sperm he cummed in my pussy yesterday."
Hearing this, Alex had an idea.
'System, I'm going to make my sister drink this glass of cum, by doing this, I want her to have a great desire to feel the same taste again.'
[Alright, I'll improve her blowjob skills so she can get a cumshot whenever she wants. I recommend that the Host shows her the photos on your cell phone so she can cheat on you faster. And don't worry, just like what happened to Mary, I will also influence her mind.]
"Mom, I want Jude to take this cum."
Mary looked at the glass and felt a little sad.
"Since it's my daughter, it's fine, but I'll just take a sip first and I want compensation in the future."
"Of course mom, in the future you will drink a lot of thick cum from strong men."
*Sip*
"Hmmm, I love this taste, I think this is the most wonderful "food" in the world."
Mary made good use of that flavor. With her tongue, she passed it from one side to the other in her mouth. Her tasting lasted a long time, with her face turning red with excitement, she couldn't help it and started rubbing her pussy in front of her own son.
"Alex, cum in the glass to fill up what I swallowed."
Alex wasted no time, taking his small dick out of his pants and aiming the tip into the glass. Pre-cum began to be released, shortly after, Alex dumped his load into the cup. The two cums didn't mix, which didn't surprise Alex, after all, Jason's superior cum was much denser.
About 5 minutes later, Jude came down and greeted her family.
"Good morning mom, good morning brother."
"Good morning Jude."
"Good morning daughter, I prepared a special drink for you to have lots of energy today." Mary said handing the glass to her daughter.
Jude thanked her mother, but looked suspiciously at the glass.
"What drink is that? It is white and has a strong smell."
"This is a special milk. It's something that took time to get." Alex replied
"Ok." Jude said, bringing the glass to her mouth and taking a sip.
The moment she drank it, she thought it was strange, but the system influenced her, with every second she liked the taste more and more. She felt the flavor and texture of something different too, it was of a lesser quality, but that didn't stop her from continuing to swallow that nectar. She felt that the drink was difficult to swallow, it stuck in her throat, but that only made her happy, as it meant that the taste would stay in her mouth for longer. Normally she drinks quickly, however, she decided to drink this one slowly to enjoy it for longer.
When she finished drinking, she licked the rim of the glass to not waste any drop of her new favorite drink.
"*Haa.* Wow mom, this is really good. Although it had another… inferior flavor mixed. Anyway, I liked it. Is there more?" Jude said while she licked her lips. There were white drops on her tongue, and the strong smell of cum was trapped in her mouth.
Alex's cock leaked pre-cum again upon hearing his sister calling his cum inferior compared to Jason's.
"I know daughter, I love this flavor too. You need to see what it's like to drink straight from the source hehe. Unfortunately it's already gone, I drank most of it yesterday, but we can get more."
Jude hearing this became excited. "And what is the source?"
Mary looked at Alex. Feeling his mother's gaze, Alex decided to move on.
"The source of that milk is Jason's balls, you're drinking his thick cum. Yesterday I asked mom to fulfill my greatest desire to be a cuck. She gave blowjobs and had raw sex all afternoon with Jason."
"I got so much cum inside me I must be pregnant now." Mary said, already thinking about how her belly would grow in a few months. Even though she hadn't gotten pregnant by Alex's choice, she was starting to like the idea of having a new child.
Jude started out in disbelief, but again with the influence of the system, she just accepted it.
"If mom sucked his dick and drank the milk straight into her mouth, I want to do that too."
Mary and Alex smiled.
"Of course sister, we can do this today in college."
"So let's go, I need to get my mouth on that dick."
Alex felt his dick getting hard. His pants had a barely noticeable bulge. Yesterday his mother had turned him into a cuck. Today it is the sister who would do this. He couldn't help but be excited.

Halfway to college, Jude, who had several doubts, looks at Alex.
"So you have a cuck fetish?"
Alex hearing this gave a smile.
"Yes I do, it makes me very excited."
Alex takes out his cell phone and shows photos of his mother fucking and sucking Jason.
"Mom had a lot of fun yesterday... And so did I."
Jude blushes when she sees the size of that cock, she felt her pussy pulsing and getting wet, but what surprised her most was the size of the balls, she instantly knew that this man would be able to produce enough milk to quench her thirst.
"Hmm, and when did you start having this fetish?"
Alex remembered the past.
"Well, I used to masturbate all day long. It was a lot of fun, but after a while, it started to get boring. My dick wouldn't get harder no matter what I did. Until one day, Jason sent a photo on my cell phone of a black man cumming inside a woman while her husband was on the sidelines watching. At that moment my dick got hard again and I found out about the cuck fetish, so I started researching. I think that was the day I cummed the most, until yesterday of course. After that day I started to imagine mom and you having sex with Jason and turning me into a cuck."
Hearing this, Jude looked at Alex. Instead of telling her brother to stop, like a normal person would do, she asked a question that left her eager for the answer.
"So, you want me to turn you into a cuck too?"
Alex responded quickly.
"I would love."
Jude didn't understand why, but she was happy with the answer.
"Then let's go to college, cuck."
CREATORS' THOUGHTS 
CuckedGuy
CuckedGuy Hey dear readers.
Sorry for the delay. My novel was blocked for having characters under 18 mixed with sexual content.
I confess that I didn't know about this webnovel rule, but thinking about it now it makes sense.
I had to tweak the story a little. You can reread it if you want, but here is a summary of the changes:
- Now no character is or will be under 18.
- Alex's late father had a company that he left to the family.
- Alex and Jude are studying business to learn how to deal with the company.
There are few changes but they give a direction to the story.
As always, if you find any errors, feel free to say so. And also, if you want some kind of cuck content you can tell me in the comments.
Enjoy reading.
