The switch fight was almost over. If he was honest with himself, it would barely even qualify as a fight to begin with. He had hit on an unexpected hot button early ("obey"- basic but classic) and once he had heard her little moan, he leaned hard into more dominant language. 

At the moment he was pretty much just teasing her- she was on her knees while he gently rotated her head, her eyes starting to roll back. He told her to be good and to obey and to switch off... 

Her eyes suddenly snapped open.

They refocused- almost overfocused. Like she could see right through him.

Predator eyes. 

 Oh fuck, he realized.  He hadn't meant to say.... 

She gave him a smirk, enjoying watching the understanding dawn on his face. 

Then- "Hands off me," in a hard, commanding voice.

His hands automatically snapped to his sides. 

She stood up. Suddenly, he was looking straight into her eyes with her hand steadying the back of his skull. A rush of words about rest and surrender and slipping- words that frankly didn't even matter when she said them  in that tone of voice.    

He let the trance take him, smile on his lips. 

He loved to unexpectedly win switch fights.
