This happened when I was 22, my cousin is 2 years older than me.
Once we were on a beach and a big wave dragged us, when we could get back up I saw that the dragging had taken out a tit out of her bikini, I tried to look elsewhere but she realized.
She chuckled a bit and took my hand, she rubbed it against her tits, she fixed up her bikini and told me
> "see, nothing to be afraid of"
And then we returned with our families, it was awkward to see her again, I'm 25 now and she has a boyfriend that seems like a serious relationship but I will never forget that moment on the beach.
I wonder if she still thinks about it.
