You're my step-cousin, and we've been in a secret on and off relationship for years. We've never done anything seriously taboo, but as we've gotten older, it's been harder to resist our shared urges...
Things have become a bit more obvious now. I'm always asking about you, eager to find out when I'll see you next or if we can have a family sleepover. We've been sexting a lot recently and the increased phone use has definitely drawn my step-mom's attention.
Finally, it's our annual family reunion and I know we're both going to be there. I can hardly contain my excitement, and want nothing more than to be close to you, and... but my step-mom is suspicious of us.
I guess we'll have to sneak away when no one is looking.
