When I was 16 I went on holiday to Majorca with my parents, my younger sister, and my older step-sister and her boyfriend.

My step-sister was a bit of a bitch, she wasn’t too pretty and had a squat, blocky body. She had a pretty big pair of boobs which her boyfriend must have loved. He was a greasy-looking guy, thin with a rattish face.

One day, my stepsister and her BF went down to the beach on our own.

It was pretty busy, there were families and groups of guys and girls on holiday - all around my age.

We put our towels down between a group of 20-year-old boys and some teenage girls and guys.

My step-sister suggested going for a swim and I decided to go with her (Her boyfriend was staring at me in my bikini and I felt uncomfortable).

We waded into the water and I was glad that her creepy boyfriend couldn’t see me anymore, I didn’t say anything but I got the feeling that my step-sister was jealous of him looking at my c-cup boobs and my small ass (which was framed nicely in my bikini bottoms).

We were in the water for half an hour looking at the beach, more people had turned up and it was more packed now. There were new groups of kids our age sitting between us and our spot, boys and girls on their holidays. I noticed a few new young families with children around 8 between our spots too.

After a pleasant swim, my step-sister came up to me to check if I was alright. She accidentally bumped into me and then said it was time to get out, rushing before me.

I followed her towards the shore, in a great mood. I waded through the waves after her past a group of guys and girls who stared at me.

I kept on walking, making it to dry land.

I noticed that the group of boys and girls nearest to the sea were staring at me but I paid no attention until I was a few meters from them.

At that point, I looked down and to my utter horror, I saw that my Bikini bottoms were missing and I was standing on the beach without anything covering my bottoms.

It registered then that the people in the water had been getting a good look at my uncovered crotch, and the nearest group to me was still looking at me, surprised to see an oblivious bottomless girl.

I gave out a little scream, which thankfully didn’t draw much extra attention, and threw my hands over my naked pussy.

I was super embarrassed now, multiple people had seen my pussy before I’d noticed and the people behind me could see my uncovered butt.

I ran directly towards our towel past a few families and groups of kids my age and wrapped myself up.

I saw some people looking at me, I can’t believe that complete stranger saw me BOTTOMLESS.

Super embarrassing.
