I've now lost count of the amount of times my seventeen year old step daughter Leanne and her eighteen year old friend Becky have either flirted outrageously with me, or as in the case last month, both flashing their breasts and Becky her very pink pussy. It all started when Becky visited Leanne and unknown to me walked into my study. I was admittedly masturbating to porn with my wife, Leannes mom away for a two day course. She caught me mid flow and I couldn't stop myself from cumming all over my hands, stomach and chest. I immediately tried to apologise, but Becky just said "Don't mind me, I'd watch you anytime".
This last fortnight Leanne has on a few occassions on her own, flirted by wearing very revealing clothing around me when her moms at work. I even overheard her say to Becky on the phone how much she enjoyed seeing my cock bulge rise. And thought I hard her say "We'll see Becky maybe I'll let him catch me naked first".
I could be imagining it all, but I seriously doubt it, and top it all Becky has told my wife she thinks I'm too young looking to be a step dad. I'm no serial perv, but if you saw how stunning Leanne and Becky are and how they look at me, you'd understand how hard it's been for me not to try and fuck them both.
