SISTER JOI is the site for all of your perverted jerk off fantasies. Your step-sister knows you've been creeping in her room when you get home from school and she noticed some of her panties are missing from the laundry. Boy, are you in trouble! She's going to tell Mom and Dad... unless you do exactly as she says. Little sis will guide you through stroking your cock with her explicit jerk off instructions. She gets so turned on watching you that she wants to cum too. This time sis uses a toy... but who knows what will happen next time.
