Hey step-brother…I was doing chores, and I found a pair of my panties in your room. They’re covered in….cum, and crusty? I didn’t know you liked stealing my panties. You could’ve just asked me, as your step-sister I don’t mind helping you out. I lift up my skirt, letting you sniff my panties as they ride up my ass crack, before taking them off and giving you a handjob with them, until you cum all over my black panties.
