I went straight to my room and lay on my bed, rerunning everything that had happened.

My head was spinning, would it happen again, should I have done more and will she tell?

Time flew by, and in a couple of hours, mum called us for dinner. I slowly went downstairs, hoping my sister Maddy hadn't said anything.
As I went into the dining room, there sat Dad reading his newspaper, and Mum was dishing up dinner. Mum said, "Where's your sister?"

I quickly replied, "I don't know."

Dad looked over his paper straight at me as Maddy entered the room. She kissed my Dad on the head and said, "Hi Daddy, evening Mum," and went and sat opposite me with that cheeky smile.

Mum said, "What's going on with you two?"

I said, "Nothing, Mum." As I felt Maddy's foot on my crotch.

Dad put his paper down and said, "Something's going on between you two. When you've finished dinner, I want you to go upstairs and sort it out. I don't want to see you till you've kissed and made up."

Maddy looked at me as she rubbed my cock with her foot and said, "Ok, Daddy."

The room went quiet and Maddy continued to rub my now rock-hard cock.

As soon as I'd finished my food, I left and went to my bedroom. I shut the door, dropped my trousers and jumped on my bed. I closed my eyes and started stroking my cock, thinking about my sister.

Suddenly the door burst open, I quickly covered myself and saw it was my sister pushing the door closed as she walked towards me. She said, "Don't stop I want to watch like you watched me."

"What about Mum and Dad?"

Maddy smiled, "Don't worry about it. Daddy told us to kiss and make up."

She stood over me, well, I slowly stroked my hard shaft.

She leaned forward, nearer my cock, "You have a lovely cock wank it for me."

"This is so wrong."

"Shhh, just enjoy it, it's fun."

I kept wanking, I was so horny; I wanted to make her happy. She moved in and kissed the eye of my big purple mushroom. I watched as my pre-cum coated her lips just before she took me into her mouth. She managed to take most of me before she gagged; it felt so good. Then she came up and licked around my helmet, then started bobbing up and down on my shaft.

It was so much better than before in her room.
Just then, my dad came into the room and walked straight over to Maddy. He lifted her school skirt up and pulled her little white cotton knickers down. I watched them hit the floor as he pulled out his fat, hard cock.

He spat in his hand and rubbed it over his cock, then spat in his hand again and rubbed my sister pussy, before shoving his cock deep in her.

She moaned around my cock as my dad grabbed her hips and started pumping into her. She let go of my shaft and looked up to him and said, "That's so good, Daddy." Then went back to sucking me.

I watched as he lifted his hand and slapped it hard on her ass, leaving a red handprint. She screamed on my cock deep in her mouth. Maddy lifted her head and said, "Yes, Daddy, spank your naughty little girl."

I lay there watching them fuck as he spanked her, and she sucked my cock. His body slammed against her ass, her ass cheeks looked sore, but she was loving it.

I watched as my sister's legs started to shake, and her breathing got faster. I knew she was having an orgasm on my Dad's cock.

Not long after I saw my Dad's ass cheeks tighten and he let out a groan, I knew that he was filling my sister's belly with his seed.

As soon as he'd pumped the last of his load in her, he pulled out and pulled up his trousers and started to leave. As he reached the door, he turned and said, "Remember, kids, no one needs to know, and keep the noise down."

Once he had left, I checked Maddy was alright, she just climbed up on the bed over my face and said, "Lick me."

I lay there looking up at my first pussy, not sure where to lick or if I'd like it. So I stuck out my tongue and ran along the edge of the lips. It felt soft and wet, and it tasted sweeter than I imagined.

So I pushed my tongue a bit deeper and slipped it up towards her little mousey brown trimmed bush as I moved up, Maddy started to moan, so I pushed deeper and found what I guessed was her clit because she went crazy when my tongue flicked across it. I continued to play with her clit with my tongue as she started to rock on my face.

I was starting to really get into it; her juicy young pussy tasted great, so I worked my way down her crack towards her tight little ass, when I noticed the juices were getting saltier and thicker.

I then pushed my tongue into the tight little hole of her beautiful pussy. Maddy was still sucking me and now squeezing my balls.

That's when I remembered my Dad had filled this hole, and the creamy salty taste was him, but I was enjoying my first time, and it didn't taste bad, so I continued.

I could feel myself getting close, so I went back to her little clit and sucked and licked it. I know I was doing the right thing as she was moaning and riggling on my face so I kept going.

Soon I was cumming hard in her mouth, which tipped her over the edge, and she squirted on my face, and as soon as her legs stopped shaking, she got off me.

She picked up her white panties and wiped her pussy. She started towards the door, then she stopped, turned, and threw her panties at my face and said, "Remember, tell no one." Blew me a kiss and left my room.
