I have been deeply in love with this girl for 15 years now. it has been non stop sex. we can not get enough of each other. But it has been hidden from everyone else. We have been doing it in the most unusual places. behind buildings, in closets at the high school, our most recent was in a grave yard..But the worst part is We are both only 23 years old, and she is my twin sister. so yes we were only 8 years old when we started. we can not commit any further because we are affraid of what will happen.
