When Patrick planned to find the lovely but trouble-bringing Marcia a husband, he knew immediately who to take her to: his identical twin brother, Richard. Richard had decided to go into wizardry rather than be a knight like Patrick, and as such, was held to different societal standards. A knight of the crown wedding a low-born woman pregnant with multiple children from multiple satyrs would be unseemly. But a wizard doing so? Wizards did far stranger things than that.
As Patrick had hoped, Richard was enthusiastic about the opportunity. Richard was too busy with his work to formally court anyone, so this was ideal for him. He was also excited about raising half-satyr children, to Patrick's perplexion.
Marcia, overcome by her body's feminine desires and urges, quickly switched her affection to Richard once she saw him. After all, he was identical to Patrick, but actually wanted her. And he was magic! Perhaps he could help her turn to being Mark. The last thought, though, was in the back of her mind. She didn't really care about it. Not right now, at least. She cared about wedding her new love.
Their marriage was within an hour of meeting. Consumation of the marriage was an hour after that, in the tower Richard lived and studied in. Unbeknownst to Marcia, Richard cast a minor spell, allowing him to impregnate her despite her pregnancy. He even sped the gestation to match the other babies. Marcia now carried ten infants within her womb. Two were identical twin boys from her new husband.
Soon, Marcia found herself keeping house for her husband and assisting him with his spells and potions. Every day, her belly grew, and her new feminine desires from the witch's potion made her eager to bring into the world some children for her and her love.
