Based on the video link I've provided above, let's summarize the eye signals and body language of DTF women.
1. Normal but Sexually Aroused. She does triangular gazing looking left and right at the pupils of your eyes in a mesmerized way and then pulling her eyes down your crotch area. She wets her lips. She gulps a little and then looks back up again at your pupils. Most of her gaze time is concentrated at your eyes. Examples: all other ladies in the video except for the ladies in #2 and #3 as described below.
2. Sexually aroused and DTF. She looks longer at your crotch area and then looks quickly at the pupils of your eyes, left-right or right-left and then back down again at your crotch area. She wets her lips and then gulps. She does the wetting of her lips and gulping at her throat several times. Most of her gaze time is spent at your crotch area. Examples: lady in white dress and big lady in blue t-shirt.
3. Hot and Ready for Sex at the John. She does very big motions of the kinesic signals as described in #2. Example: last lady in the video.
The signal for the f-close is when any of the above ladies initiates the kino. That's phase 3 of the courtship process as I've described here:

You can immediately proceed to phase 4 for the f-close with something like, "Would you like to come with me to the bathroom?" Stay silent until she says 'yes' or 'no' or don't speak a word and finally gesture with your body language to the john.
You can also simply say, "Let's go."
