She tells me that it isn’t all that bad, we were teenagers. But still, she is my first cousin, we grew up together more like brother and sister, we were not even old enough to date. Yes it was a safe way to learn with each other as opposed with someone who you don’t really know. But still having s** at 14 with her was way wrong, she is my blood relative and all her assurances don’t make the guilt go away.
