I love it when a woman wears her panties more than once and getting more of her cream on the gusset. Not sure about having them stuffed in my mouth as a gag but would definitely sniff and lick the gusset and rub them over my hard cockI have problems identifying humiliation. A little trick I love is to put back on yesterday's practical pair of thick soft cotton panties just before a session. Once my little toy is stiff as a poker and desperate for me to allow him to come I'll straddle him, drop my panties, gather them up, wipe between my legs with the gusset, form the panties into a ball with the inside of the gusset facing outwards and then use them to gag him. Ought to be so humiliating being gagged with a pair of dirty panties but it appears to turn my poor toy's on even more. I can't say humiliation, or more accurately degradation is a primary fetish of mine but it's a very useful tool for teasing an already overexcited little toy.
