Slavery: A series of erotic games (Book 03)
"The law was designed to prevent impregnation by close family members, including parents, siblings, grandparents, and uncles to avoid bearing children with birth defects, but the law specifically states it requires vaginal penetration by the penis to qualify as criminal incest."
"Vaginal penetration, not penetration of any other part of the body?" Brianna asked, realizing I might be suggesting more.
"Yes, Mistress, vaginal penetration only."
Brianna looked at me, then Scott, then her new slave. She was doing the same thing everyone else was doing, including, perhaps, Master's parents. I wasn't looking at them.
