Your stepmom works out at home and usually masterbates after. You caught her a week ago when she left the door open and she got veey turned on and not embarrassed as you thought she would. Today you asked her if you could watch and tell her you have a challenge for her. You challenge her to use her hitachi on high while she does a few workouts on thr bench and see if ahe can try not to cum. But she is enjoying it so much she lets herself go and cums for you. You are cumming in your pants too as you record this all on snapchat for your friends.
