Today, my eldest sister, Ellen had a week long school break and was taking a flight back home. Rose, my sister a year older than me, and my mum and I when to meet Ellen at the airport. We had a light exchange and Ellen said she was going off to see a few old friends in town and will be back late that night. So, mum dropped her off at a subway on the way home and Rose and I spend the rest of the day at home.

The day passed quickly and soon it was one in the morning. The house was dark and unlit. My parents and my younger brother, Josh had already went back to their rooms and were asleep. At the backdoor, I met Rose. Both of us had already left our clothes in our rooms and were completely nude and bare. We started with a bit of a warm up by 69ing in the backyard.

The sky was starless and our neighbors’ rooms were not lit. On the grass, Rose crawled on top of me and started to eat my already wet pussy. I returned her back the favour and used my tongue to probe into her pussy and arouse her clit. Our hands roamed around to grope each other’s breasts and bottoms.

Half-way through our 69 session in the cooling night, a bright flash came from the backdoor with a “click!”. I turned my head to the direction of the flash and saw Ellen with her iPhone in her hand.

“Wow, my two sisters having sex in our backyard at night. How cute!”

Oh no! We had completely forgotten that Ellen was back home.

“Ellen, it is not what you think it is! We were just just..” stammered Rose.

“Cut the crap. I saw the whole thing and I even have a photograph on my phone to prove it.”

Rose and I quickly separated from each other and used our hands and arms to cover ourselves.

“Ermm, Ellen. Can you please don’t tell mum and dad about this?” I coaxed Ellen with a sweet voice that worked on Rose when she caught me in a similar situation before.

“Why would I? I am in control of you two now. Stand up so I can get a better view of your bodies.”

“But!”

“Shut up! And listen. Do you want to wake Mum and Dad up and for them to see for themselves what you are doing now?”

Without any choice, Rose and I stood up with our arms beside us. Ellen took a stroll around us and had a view of our naked bodies. Then she stopped at the door and said,“Turn around, face away from me.” Next, Ellen passed both of us a piece of long cloth and said again,“Use it to blindfold yourself.”

Obeying Ellen’s instructions, I secured the piece of cloth around my eyes, plunging me into complete darkness.

“Stand still for the next few things that I am going to do to you.”

In the darkness and with the fact that I was at the mercy of Ellen, turned me one a little.

“Open your mouth.” and I felt something big being inserted into my mouth and strapped on to the back of my head. A pair of rough muscular hands grabbed my wrist and brought it to my back and tied it up with a piece of rope. Just then, I realize that that was not my sister and it could be somebody else. Panic took over me and I struggled, but was held tightly by a pair of arms and I tried to shout but the mouth gag prevented much sound from escaping.

Then I felt that I was being dragged away! I was dragged for quiet a distance and I deduced that I was out of my house already. Next, I felt I was thrown onto something hard and cold like metal. Using my tied up hands, I managed to push myself upright in a sitting position and then I heard a engine being warmed up. The inertia of the starting vehicle pushed me down again and I laid on the cold floor. I could feel Rose’s breathing behind my back and that calmed me down a little. At least I was not alone.

Half way through the ride, I felt a smooth hand grab my face and pulled me back to a upright position. That must be Ellen’s hand.

“Okay girls, now you are all mine. I always like to humiliate girls in public, it turns me on. Now you are in James’ van. You will also have to listen to James as he is my boyfriend, do you get it?”

I gave a slight nod.

“Now we are on the way to a park in the region and we are going to have some fun!”

The van stopped after around 5 to 10 minutes. I heard the door slide open and a gust of cold wind hit my exposed body. Ellen guided me off the van and mine blindfolds were removed. My eyes quickly acclimatized to the surrounding darkness and I saw that Rose and I were standing in the car park.

“Bye! See you at the picnic area in 30 minutes time. If you don’t make it in time, you will have to walk yourselves home.” Ellen said and closed the van door and drove off with James.

Rose and I quickly scampered to the nearest brick fence in the car park to take cover. Rose and I were panting madly and my heart was beating fast. Squatting behind the fence, we rested for awhile, the chilly breeze quickly stimulated my clit. Soon my pussy was wet and was dripping a little.

With the mouth gag, we could not talk much. I nudged Rose’s shoulder with my elbow and looked in the direction of the boardwalk entrance.
