It's Zlata Shine's birthday and her girlfriend Sofia Lee has a treat for her: a remote-control vibrator that Sofia slides into Zlata's pussy. Sofia has a blast repeatedly setting the vibrator to go off... even after Zlata's oblivious mother comes to wish her a happy birthday. Zlata's mom notices Zlata shaking uncontrollably and insists they go to the hospital to have this checked out. The sexy doctor figures out what's going on and figures out a way to turn this sexy lesbian fun into a proper threesome.
