It was a warm summer day and the end of our vacation was approaching. It had been a good one, my eyes had feasted on my older sister in her sexy bikini. But the highlight was yet to come. With two other siblings: my 20 year old sister and 19 year old brother, we had to share rooms during our sunny retreat to France. We stayed in a three room caravan and took turns taking one of the rooms to ourselves.

Tonight, I got to sleep with my sister. The room was tiny, two small beds with a gap just big enough to walk through sideways. I announced I would go to bed early that day, after brushing my teeth I closed the curtains, stripped and got into my bed.

After waiting for around an hour I heard her stumble inside, the walls were so thin that you could hear every sound from the other side of the caravan. Quickly I closed my eyes and pretended to be asleep already. Quietly she opened the door and thinking I was far gone she went to grab her pajamas. With some light from the still opened door, I got a great view of the outline of her shapely ass when she bent over. Unfortunately she didn't change in the room, not wanting to wake me. Feeling a little demotivated I waited until she got back.

It took way longer than expected, but when she returned I noticed my patience hadn't been for nothing. It was almost entirely dark, but I could make out that she was only wearing an oversized shirt. Then i pretended to roll over, away from her. She thought that she had awoken me and called out a few times. I tried my best to make it seem like I was peacefully asleep and a few minutes later I rolled over again, but this time I let my arm fall on her bed. To my dismay I felt nothing but the cold sheets.

Nothing had gone according to plan, so I turned over to my stomach trying to get as close to the edge of my bed as possible and then I felt it. She was covered by a blanked, but with my eyes closed it felt like a mountain awaiting to be conquered. Still I got no reaction, I started to panic that she might have already been asleep. So I waited a bit and slipped my fingers under the blanket, fueled by the desire to touch her big tits which had been hidden from me for eighteen years.

Having no idea what position she was in I opened my eyes just a bit. She was on her side, but i couldn't make out anything more. Slowly my fingers crept forward until I felt something, I was touching the back of her shoulders.

Then out of nowhere she suddenly moved, after feeling my hand touch her back she called out again. Not thinking clearly I decided to mumble something and pretend I was sleeping restlessly. Never in a million years would I have thought that the following would happen:

Slowly but surely she rolled over to her back and then her side so that she was facing me. She called out my name again to confirm that I was sleeping and put her hand on mine.

It was amazing feeling her soft warm hands in mine. She laid like this for what felt like an hour, then I made a move. I took my hand out of hers and began to slowly move it towards her

She gasped knowing what was about to happen and put her hand on mine again to stop me. I was asleep so i couldn't be bothered by this and continued pushing. Strangely enough she didn't stop me, and after an eternity i felt it.

My knuckles bumped into something soft and warm.

I had done it, I reached my sisters tits and she was none the wiser. Now I was on the home stretch. Trying to not immediately maul her tits, I tried to move as nonchalantly as possible and rotated my hand to it's back.

Moving forward i felt her nipple touch my palm, I moved further and then my hand was fully wrapped around one of her amazing breasts. She let out the tiniest of moans and I felt her nipple harden on my hand.

It was everything I had dreamed about and more, incredibly soft and even bigger than the tags on her bras suggested. I started softly kneading them and received even more whimpers in return.

I heard her reaching down and start fingering herself as she pushed my hand even harder against her tits. I almost came right there from feeling her big tits and hearing the fast sopping of her fingers going in and out of her moist cunt. It was a shame I couldn't stroke my extremely hard dick.

The next morning I woke up before her and tried to get a peek under her blanket. Her tits were covered up by the shirt but in between them it was pressed to her ribs making her amazing boobs seem even larger. Looking further down I saw the shirt was still drenched from multiple amazing orgasms that night.

This was my first work and ALL help is welcome, whether you have good advice or want to point out parts that you didn't like. Please comment and I will do my best to improve.
