Refuse

Deciding to be a bit mean and tease her, you subdue a smile and answer.

"No."

"Um... pardon?" Caoimhe says, taken aback.

"No, I'm not going to beg."

"Oh, um... OK," Caoimhe nods, her legs tensing up as she quickly becomes nervous and loses her focus, ending her riding of your cock as she pauses, looking nervous. "Why not?"

You don't really have a response, given that you literally asked for her to be in charge, and now Caoimhe just looks embarrassed, and even a little humiliated.

"OK," she answers meekly. "Maybe we should just stop?"

"Oh," you say, realizing your mistake. "OK. Sure."

You slide free of her, as Caoimhe pops off and lies on the bed, clearly feeling down.
