If you drive up (or approach) a girl marked with an icon on the radar and press Caps Lock (if not in a car, then Shift), she will give you a blowjob, for which you will be charged money.
If the cops are looking for you, the girl will not get into your car. And she won’t fit in any car either.
This mod straight from 2008 is a real rarity. Own animations and sounds, as well as a written script inside the main. Worth checking out.
The mod works even without CLEO - that's a plus. The mod replaces main.scm - this is a minus. Therefore, be sure to make backups of your files before installation so that you can restore everything.
