Grace and Brittney are sperm vampires and feed off manhood. One of the best and fastest ways of course is the classic blowjob sucking out every last drop out of him this of course leads the victim to transform into a women and the need to feed. Brittney just turned Grace and is showing her first hand the way to feed. Grace is both disgusted and strangely turned on. Of course Brad here will be needed some training too when Brittney is done with her.
