Being tickled while not being satisfied

Description: The girl wearing black pantyhose and swimsuit begged me to give her some stimulation. so i tied her securely to the sofa, gently caressed her body with feathers, vigorously kneaded her chest, and stimulated her genitals with a vibrating egg. she, who was physically sensitive, soon reached orgasm. but she is not satisfied yet. i fixed the vibrator between her legs to stimulate her genitals. every time she was breathing rapidly and about to reach orgasm, i turned off the vibrator. repeatedly doing this, while also tickling her. she was played with by me in great pain, but in the end she reached orgasm again.
