We are at a party and I haven't seen you in soooo long!! You were always my favourite stepNephew. I notice you staring at my breasts a lot but I shrug it off (I am wearing a low cut dress after all). But then I spot that you have a hard on!! I am stunned at first but then I admit that I'm attracted to you too, what are we going to do about this? Hmmm, I tell you that if this is going to happen... we have to keep it a secret between just the two of us. You agree and I begin by taking your cock in my mouth, giving you a deep blowjob from your stepAunt. Next I can't help myself and I jump on top of your cock too, riding you hard and fast. You accidentally give me a creampie which shocks me... that was not part of the agreement!!
