Yandere Lost boys x Oc

Everyone in this is age up so there won't be underage sexual content stuff.

Lily was the little sister of the leader of the lost boys David but not biological. Lily is only half vampire unlike David and the others except Star and Laddie but the thing about Lily is she has never shown her face since the time she turned half vampire even David who knew her before they turned doesn't even know what she looks like right now the only person who know how she looks is Laddie and Star which also comes to that star is her mate that's right when she showed her then felt sparks and knew they were but what Lily doesn't know is she supposed to have more than one mate even David, yes her they one she calls. Her brother and the others (except Laddie you like his mom but he still yandere) and the only one who knows this is Max he know she has more than one mate and that Lily should have 9.The reason he know this is because of how innocent she is and that's rare (Let's pretend that's why). So what happens when one day Star convinces Lily to get dressed up without covering her face and go to the Boardwalk where she meets some people that were to be hers and theirs and to find out David and friends are also her mates. (Sorry if this is a bad description I didn't want to make it to long)

Warning: I don't own anything and there will be sexual content and swearing
