I loved my big sister too much
I am a woman (23) and my sister is five years older. She has been married since she was 19 and I was 14. I thought the guy she was marrying was a real creep, and it turned out I was right.
At their wedding reception he told me he needed to give Marly a surprise, so I went with him to a back room in the hotel catering area. There he pushed me down, pulled my panties down from under my dress, and fucked me hard for about two minutes, then came in my mouth and told me to swallow it. I was a virgin and had never touched a man's cock. I cried the whole time, which made him laugh. As soon as he got up off me he told me that if I ever said anything to my sister or anyone about this it would destroy my sister, ruin my reputation because I would swear it never happened, and it would all be my fault. Besides, he said, a lot of girls get fucked at weddings.
He left, and I never told. I should have long ago.
Tell your sister
