Kim does nothing

Ben's embarrassment was acute. He covered his shame with both hands, backing out of the kitchen. "I'm so sorry Kim... it wasn't... I didn't..."

Ben was out the door before he could finish his half formed apology. Kim was still on her knees as she heard Ben running back upstairs. He'd been stood right there with the biggest boner she'd ever seen, she thought. She'd wanted to just reach out and touch it. He must have been looking straight down her top. Once again she felt outrage at the intrusion, but it was more than tempered by her lust.

Kim's pussy was burning with desire. She contemplated chasing Ben up to his room and letting him know how horny she was. That was not a good idea, she reasoned with herself. Best to leave it as an exciting, if awkward, encounter. However, she could think of no better way to get back at her unfaithful husband than by fucking his son.

Kim sat down in the kitchen with a cup of tea and attempted to calm herself down. She still felt extremely horny. Kim needed some release; easing her hand inside her panties she tickled her clit gently with her index finger. That felt good. Her finger stroked over her clit in shallow circles, massaging and stimulating.

As she thought about Ben and his huge erection she began to move her hand faster and faster. Kim slipped a finger inside herself, wishing it was Ben's dick thrusting into her. She had stopped teasing herself and was fast approaching orgasm. She was so turned on it didn't take long to orgasm. As she did, Kim slouched into the chair.

Before long Kim was back in bed. Her encounter in the night had taken her mind off her husband's cheating temporarily, and she slept soundly, dreaming of her step-son's young body.
