Blair has always felt close to you, her favorite stepUncle. You have always been there for her, at her gymnastic meets, babysitting when she was younger. Now she's an adult, and she wants to show you how much she appreciates you. She asks you to lay down on the couch and starts rubbing her hand over your pants. You can feel yourself swelling as your big-breasted stepniece unzips your pants and pulls out your cock. She has had a crush on you for years, and now she is finally getting what she wanted. Her hand feels amazing, but you know how wrong this is... if your step-sister ever found out you were messing around with her step-daughter, you'd be in big trouble. She stands up and takes off her top, showing you her perfect big natural tits. She wraps them around your cock and slides up and down. It feels so good you can hardly hold back. You might cum any moment! You're surprised at how good this feels - probably because it's so wrong!
