Being adopted has its perks with a hot step-sister (Nina Skye)

Being adopted is awesome when you have a super sexy and slutty "step-sister". Growing up she would walk around almost naked in front of me making me so fucking hard I would jerk off in my room for hours thinking about her perfect tits and ass. I always felt like such a pervert until my parents told me I was adopted. Every since then, all I can think of is how good my cock would feel in that pretty mouth of hers and how it would be perfectly fine for her to do it. Because, after all. She isn't really my step-sister at all.
