I trembled as she looked up at me and licked me faster, forcing me to breath harder and heavier. Moving my head side to side, I felt myself almost clo...e to coming as she flicked her tongue across me, nibbling my clit in between. I had my legs fully spread for her and wanted her to carry on licking me, but instead, she stopped and planted kisses all over my stomach and breasts before moving to kiss me on the lips.
