Slip the panties in your pocket and quickly leave her room ?
From Create Your Own Story
I put mom's panties into my pocket and dashed back to my room, just in time, mom came up the stairs and into her room.
I was hoping to get a glimpse of her as she walked along to the shower room, in just her panties and bra. My mom has a great body with the nicest arse I have ever seen, wide arse with slim waist, so hard-on inducing.
