So you woke up with a device around your dick and unable to get hard. Why? I'm sick of you watching Me and jerking off to Me. I know you think you're sneaky but I've seen you out of the corner of My eye many times. I thought you were over it but apparently you aren't. I'm your stepsister and that's disgusting. It doesn't matter that We're adults now. We grew up and were raised together. Now you'll be permanently locked in chastity and unable to ever jerk off to Me or get hard again.
