Pete woke up and smelled eggs and bacon. He stepped out of his bed, grabbed a towel and walked to the bathroom.
Still half asleep he opened the door and walked in. Inside he noticed his younger sister Christy was in the shower. He didn't move and looked at her naked body. She certainly was a good looking 18 year old girl. She was petite, about 5'4" with a cute butt and pert breasts. Pete guessed it was a B-cup. Her nipples were hard and between her legs he saw a small dark landing strip.
Then he looked at her face and noticed she was smiling. She was staring at his cock. Now he became aware that looking at his naked little sister gave him a huge hard on. In the past he had seen her naked more often. Though that was a while ago and he didn't see her completely naked after she had blossomed into the gorgeous girl he was looking at right now. Christy giggled, "You like what you see?"
Pete smiled and looked her in the eyes. "Ow yeah... I certainly do! Just like you seem to like what you see."
Now she laughed. "Like it? Hmmm.. I think I do. Though all that matters is, does a guy know how to use it."
With a wicked grin she looked at him. "Now get out of here pervert. Looking at your naked baby sister and getting a hard on. You should be ashamed."
Pete laughed. "I should be ashamed? My baby sister shouldn't be talking like that, nor should she be looking at her brothers hard on."
He softly slapped her butt and turned around. "Hurry babe, Mom is busy with our breakfast and I would like to take a shower first."
"Hey bro?"
Pete looked over his shoulder. "Yes babe?"
"Do you?"
"What?"
"Do you know how to use it?"
Pete pointed his finger in her direction. "You better be careful girl."
"Why? Are you going to show me that you know how to use it?"
"You would like that, wouldn't you? Naughty girl!"
Christy laughed loudly and she slowly moved her tongue over her lips. Then their mother Susan shouted. "Breakfast is ready, hurry up!"
Pete raised his eyebrows. "See what I mean? Breakfast first I guess."
When he entered the kitchen Susan was taking the warm breads out of the oven. She was wearing a short robe and because she was bending forward, Pete had an unobstructed view on her legs and most of her behind. She was wearing panties, but these were very small and not able to hide her gorgeous shaped butt.
His memories went back to the night after the family party. The night that he slept in his parents bed, next to his mother because there was no other place to sleep. The night that his mother thought he was his father and he and his mom had great sex together.
A cough and a giggle brought him back to reality. His mom had turned around and had a big smile on her face. "My boy seems to like what he saw."
Pete pretended not to understand what she meant. Then Susan stepped forward and with her finger she touched his hard on. "Put that away sweetie before your little sister comes in for breakfast."
He noticed that looking at his mother's sexy butt had made his cock hard again. His hard on was poking through his robe.
She kissed his lips and continued preparing breakfast. He sat down and when she put things on the table she glanced at his cock. "That big guy is still poking through your robe," she smiled.
Pete chuckled. "Yes, I know. And your finger touching that big guy didn't really help."
She giggled. "I have memories of more than only touching with a finger." "MOM! So do I. How am I supposed to sit here without a hard on with that spectacular night in my mind?"
"So you think this won't help either? " She said and opened her robe, flashing her beautiful big breasts.
Before Pete could say something, they heard Christy walking to the kitchen. Susan quickly closed her robe and Pete tried to hide his hard on. He was wondering what caused his mom to act like this. Since that terrific night there had been some hints, but basically what happened that night was kept unspoken.
When Christy took a chair and sat down, she whispered in his ear: "Is that still because of me or is mom also giving you a hard on?"
Susan heard the whispering and asked Christy: "What did you say? Did I hear you whisper about your brother having a hard on?"
Christy's face colored red. "I'm sorry mom, but he is sitting right next to me with a huge hard on poking through his robe. I think he is getting turned on looking at us when we are naked."
Susan looked surprised. "Well you and I are not naked sweetie."
"Yes mom, I know, but when he entered the bathroom I was completely naked and I assure you that his cock liked it."
Pete didn't know how to react. "Come on you two, give me a break please. I could not help it that Christy was completely naked when I entered the bathroom. Neither could I help it that I saw your half naked behind and your naked breasts."
Susan sighed. "You should have covered your naked body Christy. And you mister, you should turn around instead of getting turned on by looking at your sister or your mother."
Christy giggled. "Ow yeah mom, and you better wear something less revealing or else your big boy will get turned on and suddenly you will find yourself being fucked by your big boy."
For a moment both Susan and Pete didn't know how to react, there was a silence.
Christy's eyes flashed from her mother to her brother. "Did I say something wrong?"
Again she looked at both of them and she grinned. "Noooooo... Did you..."
Susan recovered and interrupted her. "No dear, nothing is wrong. I just think you should not use that kind of language. It is a ridiculous thought and talking like that could cause a lot of problems."
"Ok mom, I am sorry, but I can't help it that his cock has its own mind," she said. "Neither can I help it that his cock really looks nice. I'm sure you have seen that like I did."
Susan looked stern at Christy. "It's enough now young lady. Eat your breakfast!"
*************
Pete came home late in the evening. In the house everything was dark. Quietly he walked upstairs to his room.
When he was about to open the door of his room, he heard some noise. He walked to the corner to see where the sound came from. Carefully he looked around the corner. In the dark he could see Christy standing at the door of their parents' bedroom. He heard the sound again and he saw Christy. She was naked and she had her hand between her legs. This was interesting.
On his toes he got closer. The door of their parents' bedroom was ajar. Christy was looking inside and was so concentrated that she didn't notice Pete. She was playing with herself while she was looking inside the room. Pete could now see what she was looking at.
Their dad was sitting on the edge of the bed. On the floor between his legs he saw their mom sitting on her knees. Both were naked. Susan held Mark's cock in her hands, slowly moving her fingers up and down. Her tongue licked over the head of his cock. Then she took him in her mouth and his cock completely disappeared.
