Thought It Was a Secret

Hey, i am an 18 year old guy from England. I live with my parents and my sister. My dad is 50, mum is 42 and sister is 16. My dad is a business man and often is away for 2 or 3 weeks at a time, we are fairly wealthy and my mum is a house wife.

On to the story. When we were younger me and my sister shared a bedroom and things like baths...it was seen as a good thing to do by our parents that way one could always keep an eye on the other. Well we did more than that and when we were in the bath would often play with each others private parts - my sister especially like to play with my cock. When we stopped sharing a room and sharing baths it didn't stop us playing with each other. At the age of 13 i recieved a handjob from my 11 year old sister and we never looked back. Blowjobs and pussy eating soon followed. It became so we would try to get it on every chance we had - we would take it in turns making sure at least one of us was pleasured each day.

About a month ago things changed. After school one day my mum walked in on me standing naked in my room with my sister naked on her knees infront of me jacking and sucking my cock. My heart stopped as i expected my life to end. To my surprise my mum din't react angrily but said she'd guessed a long time ago we were doing these kinda things but din't know what to do about it. We said it was purely a pleasure thing. She said she understood but said it had to end before our dad found out or something else went wrong and before it got too late to stop. She did however say that we could have half an hour more and the left the room. We decided to spend that half hour in a 69.

The next weekend our dad was yet again away in Japan on business. My sister was also staying over at her best friends house - my mum had suggested this - i figured it was to keep us apart - but i don't think she would if she knew my sister and her friend spent all their time with their tongues in each others pussies.

That Saturday night me and mum went out for a meal as a treat seeing as the other two weren't around. When we returned home my mum brought up the issue of my antics with my sister. We had a horribly frank discussion about sexual matters and she said she understood we only did things to pleasure ourselves. Then to shock me my mum propositioned me. She said she would allow me and my sister to carry on if she was allowed to join in. She explained that dad wasn't able to please her anymore and he hadn't been for sometime and said that when she was younger she has experimented with girls and enjoyed it. She stressed there would be no penetrative sex and she could teach me and my sister how to satisfy better.

I thought about this bizarre proposal for a minute and then said it was fine by me if my sister agreed (i was sure she would) My mum then asked if i would like a handjob. I din't refuse. All that experience came in to play and it was better than my sisters attempts. Also my mum has large tits so i discovered the tit wank.

I'm sure if anyone could see in our house when my dad is away they'd die. They'd see a 42 year old mother, an 18 year old son and a 16 year old daugther enjoying handjobs, blowjobs and pussy eating.

We think its ok if it doesnt get to sex. Its just pure pleasure which we all enjoy.
