Changing lanes without signaling

It's when a man goes from the vagina to the anus in one quick motion without warning his partner.

I was changing lanes without signaling on Renee in the shower and she went deaf for a minute.

When you go from vaginal sex to anal sex without warning the girl. Must be done in a quick fashion.
