But, Jess is known to be the mistress of scheming and so, don't mess with this vixen. For now, Jess will play along with whatever Tess wishes for her to do as whatever Edward wants from Jess. " Yes, Master. I eagerly await my lessons and my new lease in life to please you, to make you happy to do what Tess wants too. Thank you for accepting me as your slave and into your family, your home. We will get along just fine, lovely Tess." Jess says in a sincere tone that they can see is sincere  as she sweet talks her way into their hearts. She can't wait for the master / slave events to begin. She assumes there are more surprises in store for with these two and Jess is ready for it all.
