I noticed you've been staring at my feet a lot lately- especially when I'm wearing pantyhose. What's even more- I found a pair of my used pantyhose is my room! I may just have to tell mom about it, how you've been probably sniffing and smelling them after I've worn them all day then jerking off into them. I figured I can make a deal with you- I won't tell mom about this if you don't tell mom that I've been sneaking out with friends! Need me to sweeten the deal? Fine, I'll even rub your cock with my pantyhose covered feet- but NO telling mom and dad!" Wrapping her soft pantyhose around your throbbing cock, your step-sister rubs her stinky pantyhose all over your cock, teasing you about your freaky foot obsession, until you blow your big sticky load all over her pretty pantyhose'd feet.
