In the house alone

It all started when I was 16. Me and my twin sister were alone in the house, my Dad and Step-Mum had gone on holiday for 2 weeks and left my sister Becky in charge.

We were getting on just fine but three rather boring days of watching movies had passed. We decided to watch one more movie and then get something to eat. Becky told me to go upstairs and pick a movie out of dads office but we had watched all the movies we had in. So I started to look if I could find some new ones. After five minutes of not been able to find any I saw the corner of a dvd box under the desk. I picked it up but the was not any cover and the disk did not have any name. "Damn, it’s a blank," I thought.

I continued looking when Becky shouted, “Emma hurry up.”

So I grabbed the blank disk and ran down stairs at the same time saying "I had found a dvd but I don’t think there’s anything on it."

When I got downstairs beck said, "Well, have a look".

I put it in and pressed play. The next thing I knew was my sister shouting "OHHH MY GOD!" I turned around and on the 52inch TV was my dad and my aunty, his sister, getting it on.

"Turn it off!" Beck screamed but I just sat there watching in amazement. Then she turned it off. For some reason, I don’t know why, I demanded that she put it back on. Which she did. After five minutes of watching my dad’s cock, which must have been at least seven inches long, fucking his sister, I got up to turn it off.

When I heard I small voice saying, "Please leave it on". I turned around to face Becky. When I saw her rubbing her self, all she could say was, "Are you going to help me then?"

I had always admired my sis’s body and those 32C boobs, we were both used to seeing each other nude. Sharing a room means you have to be. It's then I noticed that my pussy was so wet for my aunty. I quickly nodded my head and sat on the sofa. Seconds later, Beck was tearing my clothes off. By this time somehow she was already nude.

She gave me the most passionate kiss I have ever had. Then she paused for a second and said, "How about we leave Daddy and Aunty Claire a little present and film this for them".

I said, "yes," just to get her back to fuck my ever more hungry pussy.

She set up the camera and then started to eat my virgin pussy, I couldn’t believe it. The first time of having sex was going to be with my sister whilst at the same time watch my aunty get fucked by my dad.

Then I felt the most amazing feeling ever. I looked down to see my sister fingering me this feeling was building. I didn’t know how much more I could take. Two minutes later that was it. I couldn’t take it. I had reached climax, the most amazing orgasm ever followed.

I quickly filled my sis’s mouth with my juices, She quickly swallowed and said, "It’s much better when someone does it for you isn’t it."

Then she said, "Ohh by the way you should close the door when you masturbate. Me and dad have been watching you for months."

I just looked up smiled and said, "Ha-ha yeah I know. Why do you think I leave the door open?"

Keep a watch out for part 2.
