Porn Broadcast! 12 Hours of Brother-Sister Sex

* Introduction
"What if you invited your brother, sweetie? He's always so nice to you, and I bet you'd make a nice couple."
Maybe she didn't mean it the way I heard it, but my heart leaped into my throat.
That's exactly what I was fantasizing about. Inviting my brother on a romantic two-week vacation to the cottage.
Even so, knowing that this trip was so I could have sex with him, his response was tepid.
So I said, "Okay, how about this. We're going on vacation in two weeks.
Until then, you're not allowed to masturbate. I won't masturbate either."
That way we'd both be so super horny when we got to the cottage, and it would totally happen.
While I was planning his seduction, my brother said:
"When we go I wanna do a live stream. I've always been proud of you, sis, I want to show the world."
I wasn't very excited about my face being online, let alone... you know what... but I said okay.
Then, for the first time, we kissed.
