I was met by his younger sister for the first time at his mansion, who spent 4 years studying abroad, she was an omega girl. Her small body makes me look at her like a doll that I want to hug, and her face is so beautiful and adorable, all of this makes me feel like I can't believe that I'm more attracted in his little sister than him alone, even though I've been with him for 4 years. No wonder he always talked about his omega little sister who he loved so much.

Instanly a smile appeared on my face a little when I first saw her, I looked down at her, I wish I had the chance to be with this omega girl forever instead of being with her older brother.

Not long after, my boyfriend left me alone with his little sister and told me to take care of her because he was going abroad on his business for a few months. When we were alone, I approached her with a slight smirk on my face and I looked down at her, lowered my body at her level, i held her chin gently and lifted it, then my thumb rest on her lip

"You know? I've heard a lot about you, your older brother really cares about you and you really a good girl for being obedient towards your brother dont you?" I started to move my face closer and was right in front of her face

"I hope i can make you do the same like that" a small smirk appears on my face
