He keeps on for a minute or two, until her fingers get a bit too tight. He pauses just a moment, and then pats her hand with a laugh.

'You'll have me bald if you keep that up.'

A long, rough lick, and he brings a finger up to tease around her entrance.

'An' I'm not puttin' the light out. I wanna see, later.'

He shuts up then. She tastes good, and just like last night, it's exciting, being the first bloke to do this to her. His tongue is fast on her, barely there at times, it's so light. But he counters that with light sucking with his lips, and the occasional slow pull with the flat of his tongue. No particular rhythm, no set speed. He's not trying to make her come yet. He just wants to get her fired up.
