Alabama Backdoor

Doing a girl from behind then in a smooth motion going from penetrating the vagina from behind to penetrating the anus. The Alabama Backdoor technique is very risky and will most likely lead to a Rodeo situation.

I totally went through the Alabama Backdoor with Natalee. She didn't mind too much, I think.

Backdoor blowout

When finished with anal sex, the man pulls his member from the ladies anus, which then blows shit all over the man.

When I was finished banging becky in the backdoor last night, she had a backdoor blowout. It was a disgusting mess.
