Priceless by Cassie
Sesshomaru is the CEO of his father's company. On his way home from work one night, Sesshomaru's beast stirs, which hasn't happened in over 200 years. What could this mean? Sesshomaru had kept it locked up for so long, why is it coming back to the surface now of all times, and what is with this odd sense of urgency? Rated mature for graphic depictions of self-harm and abuse, as well as some strong language. Be warned!

Hello all,
