It was late Saturday night, everyone in the Hannigan family had gone to bed except for Jack who was up in the kitchen getting a glass of water when he heard a quiet thumping coming from upstairs. He finished his glass and started to make his way back up to his room when he heard faint moaning. His cock sprang straight to life, recognising the moans as Candy's.
"That little whore just can't get enough!" he thought to himself.
He walked up to Candy's bedroom door and slowly opened it. There was Candy lying on her back with their Dad now lying still on top of his little sister, startled by Jack now standing in the door. "Ah son.. I.." he started..
"Daddy it's okay" Candy moaned into his ear. She started writhing underneath her Daddy, wanting him to keep fucking her. His cock stuffed deep in his little girl's sopping pussy Peter Hannigan started moving in and out of her hole again with his eldest son now watching.
Jack stroked his cock while the show continued on the bed in front of him. Candy was holding her knees up high so her Daddy could fuck her deeper and it was obvious that their father wasn't going to last much longer the way he was grunting and telling her how good her pussy felt around his fat dick.
"You wanna cum in your little girl, Daddy?"
"Ohh fuck, I'm gonna cum in your tight little pussy baby, uhh.. uhhh...." Peter called out as his thick cum shot up his little girl's pussy.
"Mmmmmmmm Daddy you dirty old man, filling your daughter's fuckhole with your hot cum" Candy moaned underneath him, still slowly grinding her pussy up against her Daddy.
Peter crawled off his little girl's bed and headed back towards his bedroom, passing Jack in the doorway.
"Probably best if you don't tell your mother, son" Peter said with a hand on Jack's shoulder.
"So how long has this been going on for?" Jack asked as he walked towards his little sister who was still lying on her back in bed massaging her tits with one hand and the other reached down playing with her cummy pussy.
