Rebecca Helen Elder, 39, pleaded not guilty to one count of aggravated serious criminal trespass at the man’s home, and one count of rape.
She appeared in Adelaide’s District Court this two days ago.
At trial, prosecutors will allege Elder, of Parkside, broke into a house while its male occupant – who cannot be named – was lawfully on the premises.
They will also say she broke in with the intention of committing a further offence of rape.
Finally, prosecutors will accuse Elder of raping the man by performing an act of oral sex without his consent.
Judge Wayne Chivell remanded Elder on continuing bail until a directions hearing next month.
