With a flick of her wrist, she unhooked the skirt, but in doing so, she lifted it high for a moment. She heard the sharp intake of her son's breath – she had just shown her tightly pantied ass to her son.

"Is there anything special you want, honey?" she asked.

By now Johnny was pushing the cart with one hand, his other hand stuffed into his pocket to bide his bulging hard-on. She let her eyes linger on the front of his jeans for a moment, then when he said he didn't want anything, they went to check out what small items she had selected.

As she stood waiting for the purchases to be rung up, Johnny slipped past her from behind to help bag the items. Jennifer felt the hardness of her son's cock brush over her ass, and her breath caught.

Johnny loaded the grocery bags into the trunk of the car, and Jennifer could not resist one more exposure. While her son was busy, she hooked the hem of her skirt to the edge of the trunk, and when Johnny closed it, her tight skirt was held high.

"I'm caught, Johnny," she said, trying to keep enough skirt over her legs. She handed him the key. "You have to open the trunk for me."

While he fumbled with the keys, Johnny was looking at his mother. She was sideways to him, and he was seeing the swell of her lacy panties, the curves of her mouth-watering ass. Just a little more and Jennifer's skirt would be around her waist.

When she was in the car, her skirt was again high, and this time she made sure the creamy flesh above the tops of her nylons showed.

Johnny had a very hard cock all the way home.

While her son put away the purchases, she went to her room and sat on her bed, hands folded in her lap. She was excited, very excited. There was no doubt that Johnny was looking up her dress every chance he had. And getting a hard-on, too.
