Are little brothers the ultimate cuckoldry?
I cannot think or comprehend of anything more cucked than having a little brother. Honestly, think about it rationally. You are feeding, clothing, raising and rearing a boy for at least 10 years solely so he can go and ravage another woman. All the hard work you put into your beautiful little brother- reading him stories at bedtime, making him go to sword practice, making sure he had a healthy diet, educating him, playing with him. All of it has one simple result: him body is more enjoyable for the women that he will eventually fuck in every hole.
Raised the perfect boy? Great. Who benefits? If you're lucky, a random woman who had nothing to do with the way he grew up, who marries him. She gets her tight pussy fucked every night. She gets the benefits of his kind and sweet personality that came from the way you raised him.
As a woman who has a little brother, you are LITERALLY dedicating at least 10 years of your life simply to raise a boy for another woman to enjoy. It is the ULTIMATE AND FINAL cuck. Think about it logically.
The ONLY way to prevent this is to marry your little brother yourself.
