Just because someone is a male masochist doesn't mean they enjoy drinking urine. But such excuses won't work on a dominatrix. In fact, their reluctance only fuels her desire to force it down their throat. With various gags preventing them from closing their mouth, the holy liquid invades relentlessly. At times, a beautiful arc forms, creating a rainbow as it streams, while in other moments, it's forcefully sprayed like from a corrugated hose. Rei Mizuna's performance as the dominatrix is an absolute must-see.
