When banging a MILF named Barbara you pull out of her ass and try to blow your load in her mouth and her son named preston walks in and catches you in the act and you lose your erection
So I was balls deep in prestons mom last night and I was just banging the shit out of her and doing work and right when I pulled out of her ass and was ready to give her a deposite in her mouth preston walks in and right away I get the invisible door.

A close friend who feels comfortable coming into your house via the side door, probably off the kitchen. You, too, are comfortable with this friend entering your house through the side door. A side-door friend is probably one of your best friends. Conversely, front-door friends are those acquaintances you are not all that close/comfortable with.
