Arguably the worst mistake you could make is hooking up with a family member. Is there ever a way to come back from that?

This story comes to us from the subreddit Today I F**ked Up. And well, yeah. When you accidentally go on multiple dates and end up sleeping with your first cousin...That's how you know you f**ked up.

But there's something about this story specifically that burns a little deeper and slower. Maybe it's because we've all heard the sleeping with your cousin trope. Whether it's in movies, or shows, or jokes. But this story is unfortunately VERY real.

Not only did these cousins sleep together, but they also didn't figure out they were cousins until they attended an actual family function together. Yikes, yikes, yikes! I don't want to spoil it for you, so I'll let the Redditor tell the rest, but buckle your seatbelt. You're in for a wild ride.
