i wear CK microfiber boy shorts, purely because they are so soft and its bliss when the fiber rubs against my clit. also, they make my ass look great. ooh, yes i do like to cum on my panties (i gush more than squirt, not a lot really but enough to soak most of my panties). it feels so naughty when i cum on my panties and then pull them back up against my puss, making it squelch as i walk, FANNY FARTS!!
i would reccomend the microfiber sort for sure but make sure to wash them regularly to keep them soft if you are cumming in them a lot
