Your step-mom is looking for the laundry detergent, she knocks before entering your room but you aren't quick enough to hide the evidence that you were jerking off.... with her dirty panties! She's MAD and disgusted with you... She throws the panties back at you and demands you continue jerking off with them on your face like an idiot. She takes out a riding crop and hits you with it, she'll hit your thighs while instructing you to jerk off to her panties and big tits. You can't deny her, you can't say no- you just helplessly start stroking right in front of her as ordered. The crop hurts as it hit your thighs, you feel a deep sense of shame but you are so turned on you can't help it. Your hot step-mom tells you to cum all over yourself while humiliating you.... you cum so hard and so much. She laughs at you.... She hopes your thighs and cock will be sore for days- you disgusting pervert!
