I caught my stepmom having phone sex so I decided to join in on the fun from the hallway by playing with my cock. Stepmom caught me, but that did not really distract her from her call. She stayed on the phone and started to please me while she was still on the phone with my dad. I felt pretty guilty, but also pretty awesome. My stepmom was an outrageous cock sucker. I loved the way her pussy felt too. I came all over her ass and my dad will never know that all the moans he heard on the phone were meant for me and not for him. Am I a bad son, or am I just that fuckable?
