A girl in front of me showed off her panty flash. Your dick is already fully erect. So, what do you want to do with your fully erect dick? Have her take off her panties and put it in her pussy… no no! Since she's wearing such cute panties, taking them off would be a buzzkill! The girls understand your feelings, so don't worry. They'll keep their panties on and let you stick your dick inside them for pleasure!
