He got bolder with her, watching her from other places; he'd peeked down the hall into the kitchen when she'd be doing the dishes in a pair of tight, white shorts, spurting his cum into his hand as he peeped at her motherly, chubby ass. Her panty lines were visible through the white material of her tight shorts, and he got very aroused and spurted his cum copiously as he masturbated to this erotic view of his mother.
The height of his peeping occurred when she took a shower one night.
He snuck into her room and slightly parted her curtains so he could race around to the backyard and watch through her bedroom window as she emerged from her shower, completely naked. It was at first weird to see her completely naked like this, but soon he was aroused. He'd gotten hard by this point and already had his cock out in his hand as he watched her come out and stand before her mirror. He had a pair of her used panties, and he sniffed and luxuriated in the musk of her pussy while he watched her towel dry, mesmerized, at the sight of her soft motherly hips and naked ass; he stroked his cock in his amazement!
She put on a pair of white panties and was bent over rubbing lotion into her thighs, and this caused her son to begin spurting his hot cum against the outer wall of her bedroom window, and his heart beat wildly as he watched his mother's tight pantied ass, sniffing the pungent odor of her cunt while he came!
As his orgasm receded, he watched as his mother slipped into a baby doll negligee, her white panties enticingly visible through the sheer baby blue fabric.
