She comes home and her panties are soaked. you can't stop her from going out and partying all night but you can try to figure out what that wet spot is. the only way to know is to get on your knees and lick it. maybe she was soaking up all the flirting and teasing and her pussy dripped. maybe someone was in those panties rubbing out the juices. it might even be someone else who left his trace on your girlfriend's underwear. the only way to tell is by scraping your tongue across the gusset. rubbing your cock on her sticky, cummy panties is the only way you get pussy.
