Love 'accidently' slipping up my girl friends ass hole, first time it happened she was in the middle of an orgasm, her pussy pushed my cock out, I tried pushing it back in, I thought I was back in her pussy but actually it was her arse, she both loved and hated it but she orgasmed twice as hard from anal, pretty much get told I can give her anal but don't tell her when I'm going to put it in.
