I kinda like a freaky girl, one that wears something erotic. I prefer some form of sexy lingerie, specifically a fishnet outfit that has accessible holes to her vagina and butthole. A good example is, when I step inside, she's already into it, playing with herself with toys, making good moans, and setting the evening to a memorable session.
A girl that's really into it knows how to set the atmosphere and put on a climactic performance that will win five stars from the theater. That is sexy to me. She convinced me that she is in to me, and puts on a good effort or act to please me.
