"The King" by John Abbott in Upstreet

The swinging door that opened up to the living room was closed. Reggie pushed it open a little. The room was dark except for the light he was letting in from the kitchen. He stopped when he saw his Mom and Paul on the couch. They were naked. He was on top of her, his butt going up and down real fast. Reggie let go of the door and it swung shut. He walked out of the kitchen slowly, trying not to make any noise. He picked up his shoes from the mud room and took them back to the garage. Read story here.
