Last time in "Father's Fall":
Andy played a dangerous game and got what she deserved. Her Dad had to take control and put her in her place. But Mia played hooky and caught Andy and Dad in a compromising situation.

My heart was in my throat. I laid there absolutely frozen. Mia, my youngest daughter was standing in the doorway to my bedroom. How long had she been there? How much of the incestuous ritual did she bear witness to? I swallowed hard and started for the covers when I noticed Mia's sweats were pushed down a bit and the top of her panties were showing. Her shirt was up off her hip as well. I could see that tiny heart tattoo I'd heard so much about, plain as day. Was she... touching herself?
To my surprise, Mia wasn't looking at me. Her eyes were transfixed on Andy. She seemed to study every curve of Andy's body.
"Hi Mia," Andy broke the silence with that syrupy sweet voice. "Wow Dad. She's even more beautiful in person." Mia shivered and squeezed her thighs together, stumbling a couple steps into the room. She was touching herself. And she was turned on.
Mia gathered herself and looked up with righteous indignation. "Why are you calling him Dad? Who the fuck are you?" She took another step closer. She was angry. Mia had the worst temper of all of my girls, this wasn't an act. But there was something else in her eyes now. A charged curiosity. I could tell she was conflicted.
Mia was what her mother called "very bi". She'd had 2 long term relationships with girls in high school and she'd never dated a boy. I'd heard stories that she'd made out with a few guys at parties and it always surprised me how into them she sounded when recounting the scandalous details with her mom and sister.
"I'm Andy." She spoke with a quiet confidence. "I'm your half-sister. Your Dad is my Dad too." Andy looked Mia up and down and made her play. She rolled onto her back and propped herself up on her elbows. Her knees together, she turned her hips side to side slowly, as if to hypnotize her prey into the web of lust and indecency she was weaving all around us. Mia couldn't look away and it was keeping me hard.
"Andy..." I let out a low growl, warning her to tread with caution. Andy didn't care. She sat up and scooted forward on the bed, her legs on either side of Mia. She reached out and pawed at Mia's sweats like a cat with a toy.
