Alanna gave birth to twins with different dads

Osric and Alanna had sex every night after that. The servants hear their fucking but pretends they don't.

A few months after, Alanna's belly gets bigger and she tells Osric she is pregnant. Few more months later Alanna gave birth to twins with different dads because both Osric and his dad creampied her in the same menstrual cycle and fertilized her eggs with their sperm!

Osric is overjoyed to be a dad (his daughter Penelope has his eyes) but feels weird because his daughter's twin sister is also his half sister (baby Samantha has Osmond's eyes).

The Greenfield family tree has become very weird but no one suspects the truth.
