I recommend it
People. If you've ever been tempted, at all, by the prospect of incest... and if you ever feel that such a relationship is possible, I say go for it.
Tomorrow morning, my sister and I are leaving on vaccation far away, to a place where no one knows us, so we can act properly like what we are: a couple. We've been secret lover since we were in high school, and since no one can ever know about us, we only get to be a real couple on this situations. It sounds hard, and it is, but everything else is worth it. I don't think there's any other woman on Earth I'd rather make love to.
Going on vacation is great because you can be yourselves.
My brother took my virginity when I turned 14 and he was 15 and we've been lovers ever since that was 5 years ago.
I'm a 20year old female and and my twin brother and I started experimenting sexually when we were 13. We started masturbating together, then each other, then orally and had full sex when we were 15. We're both in college now and plan on living together for the rest of our lives. Since our last names are the same, it shouldn't be difficult to live as man and wife.
I've been messing around with my hot older sister for years, and, also highly recommend it if someone has the chance and are into it. Have taken a few getaway weekends as well, and, as she doesn't live in my immediate area, we've gone out for drinks and dinner where I live very often. Bartender girls at my usual place love her, and always tell me to bring her around more often. They don't know she's my older sister, only that she and I kiss and get hands-on at the bar, like a couple.
I went to a wedding reception with her once, as a favor. We only intended to stop in, make nice, then leave, but ended up staying. Had people at our table telling what a great couple we made.
