Tested by Her Web Master

Sophie's erotic journey into BDSM continues in this second book of the Web Master romance trilogy...He's my addiction, my love—my life. He's my Dominant—my everything. He's changed me, and I never want to go back. 
But now, he's asking for too much. Going too far. It's out of my comfort zone--not who I am. 
I'll swallow my pride and face my fears But something tells me he has ulterior motives for this extreme request, and I will get to the bottom of it. 
That is, if I can pass his test.
