Their father's commands echo in their minds, "You mustn't move!" Yet, innate lubrication soaks the shaft as Michelle slowly sinks down, rubbing her tight, virgin cunt along the hard length. They collapse into post-coital remorse, their taboo lust leaving them smeared with juices and fluids, seeking absolution for their sinful acts.
