cock shape becomes equine. then it grows bigger & bigger until it's a huge throbbing stallion member...After an entertaining 4 hours of watching their modified cumslut's equine cock twitch and grow and leak without climax, the Masters decided to put their renewed toy to use at their next party.
With equipment that size, it's going to provide some satisfying cumbath for the Masters' guests...
