ARM-873 A girl who fixes the rotor to Ji Po over the briefs and masturbates the nipple with the vibration of the glans

Girls who love to masturbate nipples with a rotor are appearing. Instead of hitting the rotor directly on the nipple, they seem to prefer to tie the rotor to the tip over the briefs and masturbate with the vibration transmitted to the glans. Apparently it's lonely to masturbate by hitting the rotor directly on the nipple. Please do your best not to ejaculate until the girl reaches the climax! Don't go ahead of the girls! ??
