Yes

Haley opened the door and froze. She witnessed a sight that would scar any normal child for life if she and her siblings hadn't already walked in on their parents having sex on their anniversary.
Her mother was masturbating in the bathtub and Haley could see everything, her mother's legs sprawled along the sides of the tub. Her tits heaving up and down as she panted through what looked like a strong orgasm.
"Oh Haley," cried Claire as Haley stood in shock.
"Oh my God, mom! What are you doing?" Screamed Haley as she ran from the room.
"What? No, Haley! Come back! It's not what you think!" Yelled Claire from the bathroom as Haley ran into the hallway flashing her barely covered ass to her mother as she went.
As Haley turned down the hall to take refuge in her room, she stopped dead in her tracks.
Luke was standing between Haley and her room holding his phone with look of shock on his face. He made eye contact with Haley. Haley turned red as her own brother looked her up and down until resting on her crotch.
Haley could hear her mother splashing out of the tub. Wanting nothing more than to hide under a blanket, Haley pushed past Luke towards her bedroom. She reached the door.
