"My gf and I are going through couples counseling because we are trying to revitalize our sex life. Part of the program is having sex whenever and wherever we get a phone call with the code word in it. We don't want to make you uncomfortable while you're over."
This of course could be used as a good segway into a threesome as Bofu pointed out.
