Your "stepniece" is anxious for you to finish work so the two of you can begin celebrating your birthday. Desperate for your attention, she fidgets at the foot of the sofa and begins to tease you with her body. Though you're in the middle of an important call, you find it impossible to be angry with her. She's so sweet to want to spend time with you and she seems to care so much about your special day! By the time you finish your call you're rock hard and ready for the one-on-one time she's been begging you for. After waiting so patiently, she can't wait a moment longer to have her favorite cock buried inside her. She thinks you feel even better than usual today, it must be because you're another year older and wiser. Knowing how much older you are coupled with the taboo nature of your familial connection drives both of you wild. You've always found her special, but you never imagined she'd grow up to be such a good girl. Your wife will be home in a few hours with a birthday cake, but your stepniece is all you really need.
