You are dating Christie's step-sister and you both are ready to take it to the next step, sexually speaking. Christie is going to make sure that you are the right guy for her step-sister, so you must show her your dick. After all, your girlfriend asked her step-sister for this assistance. Christie asks you to start stroking your cock for her because she needs to make sure that you can handle your dick. To help you through this, she makes herself more comfortable and takes off some of her clothing. Christie has the tiniest tits and a shaved pussy. Do you mind if Christie touches herself while you stroke? You would love to watch her stroke her pussy as she watches you jack off. Quickly, though, Christie moves her hand over to your hard shaft and takes a few strokes. She then decides that she wants to have you cum on her small titties. Stroke your dick just like that until you blow your load.
