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 step-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 step-mom about this if you don't tell step-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 step-mom and step-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.
