I get my gf off all the time with it. Shortly after she climaxes, I whisper “Coochie-coochie-coo!” She goes berserk because her clit tickles again! Her orgasms rock her body as her ticklish clit makes her explode with laughter and overloading sensation! I nibble her neck and ears while fingering her and tickling her upper body until she safe words and passes out.
