Hetero switch heavily into domination scenes with masked women. I'm a rubber and nylon fetishist, and love games clad in one or both of these materials. I find it erotic to pull on a skintight sheer stocking-mask and do the same to my partner.

Best of all, though, are military respirators. The thrill of watching a kinky, mature woman hood herself with a hideous, sinister Russian gas mask...mmmm!
