Cat, who sells panties and socks as well as masks on Snifffr, said she’s been selling the masks for almost a year. “I think people like them because they’re able to enjoy a fetish outside of their home. I think it’s like a little secret only they know and it makes it risky and fun,” she said. “It’s personally thrilling to me knowing that a mask I’ve had in my panties or shoes is now being worn on someone’s face and they’re enjoying it.”
