The set up:
Nick, the cop has invaded Kris, the dominatrix's personal space. She can't hold him at arm's length forever.
He stood, his closeness making her feel claustrophobic. She stepped back, colliding with the wall as he placed his hands on either side of her, effectively fencing her in.
He stared at her hungrily, telegraphing his need, then lowered his mouth to hers but stopped, his breath falling soft against her cheek. “C’mon, Baby, you can do this. It’s just a kiss.”
Her tongue darted out to moisten her lips and he grinned. “You’re killing me here.”
