Tao nearly vibrated, this was the edge, the answer, and he was only waiting now for a decision. If he could have, he would have flushed at the sound. Typically he was very uninterested in shifters, but they had been feeling each other out all night, and pushing buttons, looking for tender spots, and it had become incredibly charged. He dropped the robe and Tao didn't hide the way he took in the naked form in front of him. Not just appraising, but devouring.
The shifting, was too much, power, heat and he couldn't hold back the moan that slipped through his clenched teeth. Hands forced into fists in his pockets to keep him from moving. He knew that there was a kind of delicious torture in waiting, in making things wait. He felt breath move, hard and fast as he gained control, with the wolf moving farther away. It gave him a moment at least before the collar was dropped at his feet. He knealt down on one knee and picked it up, fingering it. "Two things. First," he held up the collar, "to wear or control?" He asked making sure he wanted to be collared, or to collar. He glanced back to the door still open a bit. "Second, before I close the door, there is only one rule. One. Everything in this room, stays in this room. Tools, actions, words, nothing leaves here." he warned.
