She teaches you a lesson and makes you watch while she strips down naked, making you to wait to jerk off again until she instructs you too. You want her to keep your secret about spying and jerking to her...she will, if you impress her with your cumshot. She gives you no time to enjoy and demands that you cum for her immediately! She is not impressed with the small load of cum you produced. However, being the kind stepsister that she is, she decides to give you another chance to impress her. This time she fucks you passionately and begs for you to cum inside of her...this time she is really impressed! She agrees to keep your secret...but you'll have to keep fucking her at her request!
