Incest
Teenage nightmare: parents walk in on you while you're having sex. Parent nightmare: walk in on your daughter having sex, with your son. That's what happened to one blissful sunny afternoon. What's worse is, their kids are convinced their love transcends all astigmatism, and they want to prove it to the world.
