Bath

Luke walked up the stairs with his head still swimming with thoughts of his naked mother. It never even occurred to him that it was weird to be fantasizing about his mom. All he knew was he was horny and needed some release.
Halfway up the stairs, Luke took out his phone to find some good porn to supplement his imagination about what it would be like to fuck his mom's pussy.
At the top of the stairs, Luke glimpsed Haley's ass in a pink thong disappear into the bathroom. He thought this day gets better and better.
His semi-hard cock got fully erect at the sight.
"Oh my God, mom," cried Haley from inside the bathroom. "What are you doing?"
Haley ran out into the hallway towards her room. Luke pulled up his camera on his phone hoping to get a shot of his sister's ass as she ran down the hall. Haley stopped at her bedroom door. The door was locked. Luke snapped a quick picture of the pink thong of his ridiculously hot older sister.
Haley heard the photo be taken and spun around wide-eyed in shock.
Luke had a dumb grin on his face.
"Nice ass, sis," said Luke thinking of all the possibilities for the picture.
"Oh God," cried Haley pushing past Luke and running downstairs. Luke turned to follow Haley hoping to get more when the bathroom door opened.
"Haley!" Yelled his mother stepping into the hallway. Luke stood there flabbergasted as his mom tried to adjust her towel and walk at the same time.
It was clear something happened between his sister and mom. Claire was clearly surprised to see Luke in the hallway and in all the commotion The towel slipped free from Claire exposing her fully naked body to Luke.
"Oh my God," screamed Claire as she scrambled to grab the towel, but it was too late Luke had already seen everything.
Luke stood there in shock seeing the still perfectly shaped breasts, the water drip from her well toned body, and completely hairless pussy of a mother of three. Luke managed to take a picture of the goddess before him. The snap of the camera app on the echoed through the hallway saving the greatest moment of his life into the memory of his phone.
After getting her towel back around her, Claire realized what she heard.
"Did you just take a picture of me, young man?"
