Like A Knife

Author's Notes: Written for Blood Burns Hotter Than Fire. THIS IS NOT A BASHING FIC BTW!!! Sumia is just fun to bully (affectionately).

It was as if a knife was twisting itself in Sumia’s gut as she listened to the sounds of her husband and future daughter together. Tears stung at her eyes. Her heart was throbbing so fast and so hard that she was scared that it might burst inside of her ribcage. Nausea washed over her. She didn’t know how to feel as their bed—she and Chrom’s, not Lucina’s—bed shook and shifted with every thrust and bounce the incestuous couple made.

She just knew she felt horrible.

The fact that these two didn’t respect her enough to find another room to do such an act in didn’t help matters either.

An hour ago, she was awoken by the thick featherbed dipping behind her. Before she could turn around and see what had happened, Lucina’s voice rang across the room. The undeniable scent of sex hung in the air. The slick sounds of Chrom’s cock stirring up their daughter’s insides soon filled the room. Sumia wasn’t an idiot.

“Father, oh, Father...” Lucina moaned out. Sweaty flesh smacked against sweaty flesh. Sumia didn’t dare to turn around but she could easily imagine the gentle, subtle curves of her daughter’s body bouncing with each thrust. She imagined pearls of sweat rolling down her lithe body as her face scrunched up cutely in pleasure. “You feel amazing... I love you, I love you so much. Never stop. Please never stop. I love this! I love you!”

“You feel incredible, Lucina,” Chrom whispered for the first time that night. At least, to his wife’s knowledge anyway. Who knew what filth the exalted prince spewed while she was in a deeper sleep? “...So tight. So perfect. You’re perfect, my sweet girl.”

A light, airy laugh escaped the time-displaced girl.

Sumia squeezed her eyes tightly together and tried to fall back asleep, knowing she’d never confront her daughter nor her husband for this betrayal.
