Shivers ran up Severus's spine, echoing Jennifer's touch. The touch was tantalizing but bordered on unpleasant. He wanted to jump away from her, but seeing as the bar was the direction he wanted to go he could only endure. Jennifer clearly had issues with boundaries - something Severus would need to rectify.
Severus mourned the denial of that last shot, but figured they would get more by the end of the evening.
He caught up to Jennifer on the dance floor, and grabbing her firmly by the upper arm, pulled her back against him, harder than was necessary, but he was making a point.
He lowered his mouth to just brushing her ear. "I need to make one thing clear," his voice was low, and left no doubt of how serious he was, "We touch when I say we touch." His free hand moved to her hip and traveled over her stomach - just because he had not plans to have sex with Jennifer didn't mean he did not find her attractive.
