Pitch Black/Riddick Challange

[Guest The Phoenix Falls]

I'm writing a story like this myself but would like to see it happen with someone else

So, here is the challange

Takes place after Chronicles of Riddick, after Riddick becomes Lord Marshal

He is the last of his kind and meets an Original Male Character who is also the last of their kind.

The two are predestined mates.

This must be slash and mpreg

Dominant Riddick, Submissive OC

I'm calling this the

RIDDICK'S MATE CHALLANGE
