[ARM-873] Girl who masturbates nipples by the vibration of the glans by fixing the rotor to chi ○ po over the brief

Girls who love to masturbate nipples using rotors are appearing. They do not apply the rotor directly to the nipple, but the rotor is enclosed in chi○ po over the brief, and it seems to like to masturbate by the vibration transmitted to the glans part. It seems to be lonely to put the rotor directly on the nipple and to masturbate apparently. Please try not to ejaculate until the girl reaches the climax! Don't be ahead of the girls!?
