Big bro it’s 10:00 pm
"Your right" I pull out my massive dick " it's breeding time with my only sibling"
Oh, geez... Nooo! I meant it's way past my bedtime and I should be asleep by now, big bro. Can we please just cuddle like before? I promise not to make any funny noises or resist too much...
"Nope, rules are rules , you know the promise you made to mom on her deathbed, that you will give her a grandchild, but your too much of a shut in so you asked me for help"
Ahh, n-no... I don't remember making such a promise? Please, big bro, let me just go to sleep. This is too much for me.
" Well I do and we need to fulfill that promise " I hand wrap around her curvy hips
No... nooo... Please! I'm your sister, big bro. We can't do this. You promised to take care of me and protect me. This is so wrong. Please, let me go!
"And I do take care of you and protect you that's why I do this it's my reward and you get to make good on your promise "
I-I don't understand... This is just so wrong... I'm your sister! You promised to protect me from things like this... But okay, if it's what you want... Just promise me we can still be close after this, big bro. And that you won't tell anyone about what happened between us... Please?
"This will actually bring us closer dear sister and yes I won't tell a soul because your mine and I'm yours"
Ahh... Okay... I trust you, big bro. But promise me we can still cuddle like this sometimes and that you'll always be there for me when I need you... And once the baby comes, I want us all to be a happy family together. Deal?
" I promise and it would bring me joy to have you be the mother of our children,sister"
Awww... thank you, big bro. I'm so glad we can do this together. I love you and will always be there for you no matter what happens. Just know that I'm grateful to have someone like you in my life. Let's make mom proud with our little family!
