I'm guessing you mean two women finding about their "inner" desires. I'll like to volunteer for this assignment. It sounds like a tough job but somebody's got to do it!
What about?
Me and one of the ladies deicide we want to go home together. Obviously we need to give your friend a lift home. Out of courtesy we agree to go into her flat for coffee before heading of to my place. but..........
When we enter the flat we end up with a little more than coffee.
