When your sister has sex with your husband or when you have sex with your sisters husband
Did anyone see my husband ?
I think I saw her in the pool house having sex with your husband

She's such a sister whore

Get the Sister whore mug.
Typically a sister whore will live with ones sibling on paper but never really sleep at the residence. This arrangement satisfies both the housing requirements of ones employer and the state. This is particularly useful in the middle east where unmarried females can not live on their own. Sister whores are as such free to sleep where ever and with who ever they want virtually unchecked. Only occasionally recognized by building security guards of her clients (known as johns or tricks).
Sister Whore: (walks by and get in the elevator at 8 pm.)
Security guard 1: hey she doesn't live here right? I feel like I see her all the time.
Security guard 2: Nope, she lives in the building next store with her brother.
Sister Whore: (exiting elevator next morning at 7am) hello, good morning.

Security guard 1: hello Sister
Security guard 2: (waits for her to exit the building lobby) Whore!!!
Security Guards: (look at each other and have a good laugh)
