U wanted your mom to be the first one to know that you got selected in basketball ball team so u decided to bunk school and come home early to find your bully proneboning your mom on dining table and her moaning about how his big dick is stretching her up
Once you discovered your best friends mom's big secret, you were able to blackmail her into doing everything to you. She was shy at first but now really takes control when she fucks you.
