With a yelp, Karen jerked her cunt out of her son's face. Clutching her tits behind her left arm, her right hand between her legs, she ran from the room, yelping in embarrassment, wanting to get away from her daughter's big, staring eyes.

Robbie, his cock standing up with raging hardness, couldn't move. He could only lie there and look up at Judy. His cock felt as if he was about to come at any second, and with a groan he clutched his balls tight in an effort to prevent his come juice from spewing over his stomach.

Judy was rooted to the floor, her eyes glazing glassily at her brother, at his upstanding cock, his hands holding his balls. Her small body trembled, her fists balling up and pressing at her thighs. Her sweet mouth was open in surprise.

Karen had raced to her bedroom, wrapping her nakedness in her robe, her face flushed. The flush was a mixture of still-boiling hunger and embarrassment at being caught by her daughter. She sat on the bed, wringing her hands, wondering how this was going to turn out. Judy was very close to her father, her daddy's girl all the way. Judy might tell him, and if she did, that would be end of her marriage, Karen was certain.

She realized her son had not jumped and run behind her.

Nervously, she left her room and checked his, but it was empty. Not wanting to think he was still in the living room, she slipped quietly down the hall and peered around the corner.

Robbie was still on the floor, now clutching his balls, his cock as hard as she had left it, jerking back and forth. She saw her daughter standing near the door, her huge eyes glazed, staring at her brother while Robbie looked back at her upside down.

"Robbie…" Karen heard her daughter whisper, and saw her small body shaking. "Robbie…" Judy took a stumbling step forward. She walked as if hypnotized, her blue eyes steamy and never leaving her brother's jerking cock.
