Ben squirmed his young ass on the couch, and Becky was trying to keep from giggling. Julie continued looking at them, her eyes bold and starting to smolder. Ben was wearing a new par of shorts, his chest bare. He was still small, and looked startling like his sister, yet with a masculinity beginning to form on his face.

Both were light-haired, like their father, with bright-blue eyes that were usually filled with mischief. Becky wore a sunsuit with flaring legs and an elastic waist, the top held up by two thin straps. Julie noticed, for the first time, that her daughter was starting to sprout tits. There wasn't much but nipple yet, but those nipples poked at the front of her sunsuit already.

Becky lifted a foot to the cushion of the couch, propping her chin on it, still trying to keep back giggles. Julie saw the slim thigh, and the teasing band of Becky's panties showed near her crotch. A warmth started between her thighs as she looked. There was something exciting about seeing that band of panties, so near Becky's young cunt.

She noticed Ben had slumped on the couch, his ass almost hanging over the edge, and he seemed to be trying to peek past her robe. He was trying to do it without his mother noticing, she realized with amusement.

Well, why not? Julie thought. I sucked his young cock, didn't I? Would it matter if he saw me? Fair is fair, isn't it? I suck his cock off and he wants to peek at my cunt.

No one had said anything so far, yet Julie could feel the tension in the air. There was something like anticipation between them, a heavy, erotic something. Even the air seemed to have the exciting scent of wet cunt and hard cock in it.

Julie uncrossed her ankles, testing her son. She parted her feet almost a foot apart before recrossing them. She watched her son closely, and saw his eyes widen briefly. He had seen her; Ben had caught a brief glimpse of her panties. She lowered her eyes to the front of his shorts, and noticed his cock was starting to bulge against them. Becky kept looking at her, her blue eyes starting to sparkle. This time, though, they didn't shine with mischief, but with a naughty, wicked gleam in them. Julie wondered if her daughter had seen the quick flash of her panties.
