A movement drew her gaze back to the twins.

She turned toward them. She saw Shari's small hand on her brother's knee, and it was moving, caressing slowly. She noticed her son responding to the touch by his sister, his cock was clearly outlined inside his thin pajama.

Janet's breath caught in her throat, and she couldn't speak. She could only sit there and watch the display of erotic touching between her twins. She stared at Shari's hand sliding along her twin brother's thigh. Janet stared as if mesmerized, unable to move. She saw Barry lean close to his sister and whisper to her. Whatever it was Barry said, Shari giggled and quickly darted her hand to his cock.

Janet swallowed her gasp of surprise.

Shari closed her fingers about her brother's cock, feeling through his pajamas, playing with his prick, stroking it. Janet could hardly believe what she was seeing. She felt as if she should say something, let them know she could see what they were doing, tell them to stop.

Shari was moving her little hand on Barry's cock, actually jacking him, Janet saw. Janet's eyes became wide, but they became glassy, too. She didn't want it, but she was reacting to what she was watching. Her tits swelled up tightly, her nipples throbbing with stiffness, and her cunt started to pulsate in the crotch of her panties.

Janet was hardly aware that she was rocking her crossed foot, the rhythmic ripples of her inner thighs caressing her cunt. She was only aware of what she was seeing, what she was feeling.

As if they were alone, Shari slipped her hand into the waist of her brother's pajamas, and it was obvious to Janet that Shari was holding his cock, perhaps squeezing it, stroking it. Both Shari and Barry kept their eyes on the television though, as if they weren't doing anything except watching the program.

Janet wondered how her daughter could do something like that, with her sitting on the couch, in the room with them. How could such a sweet, lovely little girl be so blatant? How long had they been doing that? Did her ex-husband know? Did her ex-husband teach them, do it with them? Did he allow such a wicked thing?
