Some times when I'm with my period I get extremely horny, and don't know if it's normal or not. I beg to my brother but in my condition he doesn't like it so the only way I have is to let him do me in the ass. Normally I don't like it very much but when I'm on my period and feeling horny as hell everything feels good and my brother loves it because it's the only time I let him inside my back door...
