Your step-sister is on the floor trying to scrub a stain off the floor. She's looking flustered and stressed out where she doesn't want to get into trouble with mum and dad, but you're far too distracted with the view you have down your stepsisters' shirt. Your cock is twitching, and Laura can see you perving. She must be feeling a bit naughty herself because she's telling to you get your dick out and wank it in front of her!
