My step-brother comes back to my place after a family 4th of July party. I am wearing a skimpy micro bikini, it doesn't take long before we start flirting with each other, I tease my step-brother and show him my tits. I take off my clothes and sit of my step-brothers face! This feels so wrong but right at the same time. We fuck in multiple positions before taking it to my bedroom and my step-brother giving me a big creampie! A few months later I have a secret to share with my step-brother...
