The Brother's Oath: Impregnating the Sister-In-Law

Maverick Spencer, my husband's older brother, sacrifices himself just to save my husband from a car accident. In order to repay him for his benevolence, my husband, Mateo Spencer, decides to move his newly widowed sister-in-law, Lily Shepherd, into our home.

Mateo tells me, "Maverick died saving me, so I must repay him for his benevolence. He was the most worried about Lily when he still drew breath. In order to fulfill his death wish, I must let Lily stay with us.

"Lily's biggest wish is to have a child of her own. I have no choice but to sleep with her. It's to repay Maverick, you see. Don't worry, Phoebe. Once she gets pregnant, I won't touch her ever again. You're the only woman for me."

But since then, Mateo pays more and more attention to Lily. At the same time, he spends less time with me. When I notice the way he looks at me icily, I feel my love for him starting to get snuffed out.

The day Lily finds out that she's pregnant is the day Mateo puts half of the Spencer family's assets under her name. Even the token of love Mateo has given to me on our wedding can be seen adorning Lily's finger.

At that moment, I know that it's time for me to leave.

Lily held her hand up to the light, admiring the massive oval diamond ring from every angle.

When she noticed me watching, she flashed a shy, demure smile and leaned into Mateo, asking, "Isn't this the wedding ring you shared with Phoebe, Mateo? It's no wonder Phoebe likes it so much. It looks stunning on me, doesn't it?"

Mateo stroked her hair with open affection. "I'll get you a bigger one if you like it, since you're bearing an heir for the Spencer family. I've also transferred half of the Spencer family's assets to you, Lily."

Lily beamed with joy but quickly masked it with a look of hesitation, feigning reluctance. "I can't do that, Mateo. I'm sure half of the Spencer family's fortunes belong to Phoebe. It wouldn't be right for me to take that for myself, Mateo."

Only then did Mateo realize I was standing beside them. He gently let go of Lily and walked over to me, a smear of Lily's lipstick still staining his neck like a brand.

"You know as well as I do," he said calmly. "If it hadn't been for Maverick, I would've been the one who died in that car crash, Phoebe. I think it's only right for Lily to get her share of the assets. You're not going to make a scene about it, are you, Phoebe?"
