"Oh, good girl," he said, almost in a growl, fingers still gentle. The effort, the tension, was more than a little of what turned him on so, the forbidden nature of it even more, but the way her tongue moved, the eagerness to please, had his body quivering like a plucked guitar string.

"Almost there... gonna give you such a fuck as a reward if you can make it." Not that he wouldn't be giving her the fuck anyway, but everything was nicer as a reward, right? He let his hips push forward, very slowly, kept his fingers light but insistent, and kept up that steady, almost reverent eye contact.
