Your girlfriend's step-daughter Katie is looking for her step-mom, but you do not know where she is. Since you two are alone, Katie wants to have a talk with you. She thinks that you are a good boyfriend to her step-mom and she wanted to let you know that. There is something else she wants to discuss, though. Katie is attracted to you and she wants to know if you feel the same about her. You do echo her feelings, but you never thought that anything would happen. You were wrong. She tells you to take out your cock and you quickly do so, right before she takes off her shorts. Clad in a light pink bodysuit, you can now get a good look at her tight body. She must get that body from her step-mother, you think. As she turns to show you her ass, you definitely notice the family resemblance. When her perky titties are exposed, you nearly lose control. Katie suggests putting your cock between them, but you know you ought not to touch her. The offer to see her pussy is almost too much to bear, but you cannot look away. Your hand is stroking your hard dick quickly, but you speed up even more after you notice her full, dark bush. Finally Katie coaxes a large load of sperm out of you. She promises not to tell her step-mom about this and you silently agree.
