sexmouse
A common fantasy or fetish which involves one person who hides in the closet of their roommate and makes mouse sounds during the day/eats cheese to create an authentic 'mouse in the house' experience. However at night, this mouse gets a bit freaky and will come out of the closet/Mousehole. Wearing appropriate garb (I personally recommend the sexy mouse costume from Amazon) the sexmouse emerges and proceeds to suck their roommate's dick and ensure to eat the dick cheese/smegma of their roommate.
