Input: Text: this happened about 5 years ago when i was 15. 
i was at a public swimming pool with my little sister and i wearing one of those string bikinis, the ones that have a piece of fabric at the front and back with string tied together connecting them.

anyway i jumped in the water and all was good until my little sister decided to go in the whirl pool. so we did and as we were going around i could feel one of the ties coming loose but i just thought i could fix it up later. keep in mind my little sister was not a good swimmer so i was holding her up.

then i felt it. the string had untied itself. so holding up my sister in one hand and trying to tie it back together with another i was in a tricky situation.
then the worst thing happened.
i bumped into someone.
i saw their eyes move down and the horror on their face when they realized.
i swam away as fast as i could, put my sister down, tied it back up then ran far far away.
