My Little Sister Slept Between My Husband And Me On My Wedding Night

My sister came to visit me during her spring break. I took her with me when I went out with friends. My coworker Sam put the move on her, I slapped him and told him she was 17. He pinned me and told me never to slap him again. I apologized and he demanded a kiss, me or my sister. He got between my legs that night. My sister complained that I had interfered, that it was none of my business if she got fucked.

I tried to make amends the next day but she was still angry.

I didn't interfere again, Sam fucked her. I got pregnant later that summer and Sam agreed to marry me. He fucked my sister the morning after we got married, in bed beside me.
