I'm cleaning my step-son's room one day when I discover something surprising. There's stains on the sheets - which I expect, he's maturing into a young man! But as I go to fluff up his pillows I discover a pair of my silky panties stuffed in there. I feel bad for snooping but I open his laptop and I'm shocked to discover he has a whole folder of photos of me smoking. I briefly think about telling his father, but decide to confront him myself. Later that night as I'm about to go outside for a cigarette I hear a strange noise and go upstairs - I accidentally walk in on him jerking off. I reassure him that it's nothing to be ashamed of and then have a confession of my own: he's not the only one with a smoking fetish! I light my cigarette and tell him that we can play a game. When I inhale and exhale normally he strokes his cock slowly, then when I leave it at my lips he strokes faster. Seeing him stroking his big hard cock soon has me wet and I begin to stroke my pussy through my panties and then wriggle out of my tight top.

Before long I can't help myself - I haven't had a nice hard cock like that in so long. I climb on top of him, lighting another cigarette and ride his cock while I smoke, telling him to enjoy the tight wet feel of my pussy as my tits bounce in his face and I exhale plumes of smoke. Before I can stop myself I'm cumming on top of him and the pulsing of my pussy makes him shoot his big hot load inside of me as well.
