A lesbian couple, Clara (Lilith Grace) and Amy (Vanessa Vega), is having a hard time orgasming lately. But on the latest visit with their gynecologist, Dr. Williams (Charlie Forde), the gynecologist is prepared to try something new to unlock their orgasming potential: urethral sounding! The couple is intrigued and willing to try anything, which leads to both of them being sounded by Dr. Williams... and it works! Feeling so relieved and horny, the couple then has a threesome with the gynecologist as a way to thank her.
