You're on family vacation at the new beach house, and Mom has no idea that you have a perfect view of the balcony from your bedroom window when she goes out there to read her romance novel. There's not much to see at first - just Mom kicking her feet up, hanging out in her bikini. But after a few minutes she starts to squirm and look around, and you notice her hands drifting to her bikini top. At first she just idly teases her cleavage, but after a moment she's got her top untied and her DD tits out. As she turns the pages of the dirty story, she slips her fingers down her bikini bottom. Eventually she just puts the book down and rubs one out under her bottoms while fondling her own tits, furtively looking around but never noticing her own peeping Tom son watching through the window.
