When Stevie saw his mother in the shorts, his eyes went wide. Susan knew he was looking at her curling pussy hair, and she arched her hips out a bit, in a not-so-subtle way to let him know she didn't mind. As he stared at his mother, Janice slipped her hand into his.

Stevie looked at Janice, his eyes showing puzzlement. Then he looked back at his mother again. Susan smiled at her son, then turned around. The two kids gazed at her tightly encased ass, seeing the arousing curves of her round ass cheeks provocatively exposed under the highs tight legs of her shorts.

Stevie was not certain what was happening; he had never seen his mother this way before. But his cock was getting hard. He looked at his mother and felt Janice squeezing his hand. Janice seemed to be glowing, her eyes misty with sexual desire.

Some music was playing on the stereo, and Susan writhed the cheeks of her ass and ground her hips to its rhythm, knowing her son and Janice were watching. She glanced over her shoulder at Stevie, seeing if he was ashamed, or if there was interest in his eyes. She saw interest, and a peek at the front of his pants was all it took to show her his cock was very hard.

But Susan also knew that Stevie wasn't going to do anything with Janice as long as she was there. Turning to face the teenagers again, she arched her tits and hips forward.

"I'm going to take along shower," she said, her eyes gleaming meaningfully. "You two get to know each other better."

Stevie and Janice both gazed at Susan's swaying ass as she left the room. As soon as she was gone, Janice squeezed Stevie's hand tighter, looking up into his face shyly.

"What would you like to do?" she asked, her voice very soft.

"I don't know," he replied, seriously. "What would you like to do?"

A shiver went through Janice as he returned the pressure in her hand. She glanced down and saw the outline of his cock. As if by accident, she let the back of her hand brush against his hard cock. She felt his prick, then pulled her hand away, giving him a shy yet knowing smile. "Want to play with my tits?"
