Sister fucking is one of those things that every good brother does. I remember when my young’uns were younger. I used to have them fuck for my entertainment while I looked on and played with myself. They would really get into it, too! My son used to love to eat my daughter’s pussy until her legs were shaking, and then he’d get on top and pound her into oblivion.
And for her part, my daughter was a huge fan of sucking her brother’s cock, too. I love reminiscing about watching the two of them together. I taught her how to fucking deep-throat that dick very early on. Then, she always wanted to do it every time thereafter!
I think one reason I love this sort of brother/sister sex so much is that I am only child myself. I always played with my parents, of course, but I had no siblings to get down and dirty with. And I always felt that was unfortunate because I would’ve enjoyed it, I think. So I orchestrated my son and daughter playing because I was living vicariously in a way.
Now, I let the grands play together, too. And as far as I know, my son and daughter still get together sometimes for some good, old-fashioned sibling fucking as well. The family that fucks together stays together, after all!
