Siena is your favorite, playful Stepaunt and you have come to visit her for the weekend. StepAunt Siena is so excited to see you and she is looking hot as ever, in her charming, seductive manner that you're never sure if she's flirting with you or just super friendly. You noticed she was wearing white, nylon panties when she bent over to put your backpack in her chair. Of course she was instantly aware that there was a bit of tension and she was quick to find things to do to fill the day. Later that afternoon Siena finds her panty drawer ajar and realizes that you have been rummaging through her panties. To her shock you had pulled out a pair of her white granny panties out of all the sexy styles she had in her drawer! Your StepAunt calls you in to confront you (playfully) about your recent panty inspection. She isn't mad and is actually quite playful. Her sweet demeaner compels you to confess that you have always wanted to pants a girl and your surprised that she wants to let you have that experience. (After all, as long as no one is talking about what happened, no one would ever know, right?) You get the opportunity a few times and she was such a good sport. That evening your Stepaunt bids you goodnight and is overwhelmed with how turned on she is by you. Her panties haven't been this wet in such a long time! Off to the bedroom she goes to masturbate, thinking about her insanely hot nephew. Your StepAunt Siena hasn't made herself cum that hard in a LONG time, and that was all because of you, sweet Stepnephew!
