I'm your roommate's sister, and I catch you stealing my dirty panties. Instead of freaking out, I have you jerk off in front of me, and we play red light green light. When I say red light, you stop touching your cock and when I say green light, you are allowed to stroke again. I take off the panties I'm currently wearing and make you smell them while you stroke for me. I'll give you a cum countdown when I'm ready to end the game and I surprise you by instructing you to eat your cum.
