Realistic non-vibrating cock looks like a normal dong but turn out the lights and turn on the cock - it glows bright red! 10 insertable inches (25.5 cm) with sculpted tip and 2.5" (6.5 cm) thick shaft. Firm balls and flexible but solid shaft becomes slick when lubricated and stand upright on flat surface. Removable light with 3 red LED bulbs with easy push button operation and a simple twist open battery case. 3-AAA batteries for light (included).
