Well they say you will do anything for your siblings... As MRs Swanson approached and asked what she can do to get a passing grade for her step-daughter..she didnt even finish her sentence and I knew what she had in mind. She took off her clothes and man did she have a smoking body. She said anything you want as she dropped to her knees and began to suck my cock. It didnt end there as she got real dirty and started giving me a rim job. Wow I said ..can I cum on your face too... she said if the is an A grade in it cum where ever you want. Well guess whose getting an A plus.
