As he moves he quickens the pace of his finger inside her ever so slightly till it's a half-step out of rhythm with everything else. His breath comes a little faster as her touches skate closer, his arousal present and heated against her. He makes no move to slake it, though, still teasing his finger up and down between her legs, slip-sliding through her juices and swirling over her clit. Softly but deeply kissing, coaxing her higher and higher with every movement of his body.
