A day later, an info story splits that 20-something years back, Julius made use of his personal semen to impregnate his or her sterility customers. Dear previous daddy, with a weak smirk, confirms from his own deathbed to Julia which he indeed covertly provided their source.

Julia, panicked, riffles through the lady dad’s documents and looks at his or her bulletin board of children in a new way. Then fling a “family event” and allow all 100 approximately of the girl biological half-siblings and distribute DNA kit to the individuals that haven’t already tested?

“Oh, you may should …” Julia stammers right at the young woman.

Sam interrupts. “Not their. My personal mom received IVF in your father’s clinic.”

Anecdotal explanation
