Mom

Matt didn't really pay close attention to his sister and their dad. She had always been flighty, and he was more than a bit of a nerd, so looks didn't really raise too much interest in Matt's mind. His mom, however, was a mystery when it came to her job. She kept talking about the millions of dollars that passed through her company, and the celebrities she would meet on a regular basis, and it made Matt jealous. He didn't recognize any of the names she mentioned, but had googled several names she had mentioned. The first few had been noted as extras in "B" movies, and one of them was a actual star, but apparently the star herself had never even been to the office, trusting her advisors to bring her tax statements in. He wondered if he would be able to get more information on better known celebrities, so he set his mind to jumping into his mom's mind.

"I'm going to go to bed early," Lily said, her eyes darting up to their father before falling back to her plate.

"Yeah, me too," Matt chimed in, "I'm still not feeling 100%, and I could definitely use a good night's sleep."

"Well, you'll both have to get the dishes done first," their dad said, "I'm sure if one washes and the other dries, it won't take too long."

Oddly enough, Lily didn't object, and Matt was too preoccupied to speak out, so the rest of dinner passed in relative silence, Matt watching as Lily and their dad exchanged glance after glance. After they all finished, Lily stood up and started putting the leftovers away, and Matt gathered the dishes while their dad went into his study after stopping at the refrigerator for a fresh beer.

Lily washed while Matt dried, and as he stepped behind her, he couldn't help but look at her. Like his mom, he had never thought of his sister as a sexual being, but the events of the day had opened his eyes to the world around him. His twin had their mother's looks, with a youthful look, thinner body and smaller breasts, she gave a look at their mom's teenage years. For a moment, Matt was tempted to jump into her, just for a moment, in order to try and get her to strip down for him, or maybe come into his room after everyone was asleep, but his curiosity about the looks on both Lily and their dad's faces during supper.

After she was finished washing, Lily drained the sink, and walked out of the kitchen without a word. Matt finished drying and put the last of the silverware away, going to their dad's study and knocking. "Dad?"

Matt heard the desk chair squeak, and his dad clear his throat before responding, "Yes?"

"I think Lily went to bed, and I'm headed up to my room. Night," he replied, trying not to let his nerves rattle his voice.

"Okay, Matt, sleep well."

He went up the stairs, his eyes darting to the closed door to his parents' bedroom before he turned into the bathroom, brushing his teeth quickly. He didn't spare a thought about his sister next door, or his dad downstairs as he finished up, wiping his mouth before going into his bedroom. It had been at least thirty minutes since his mom left for work, and at this time, that should be more than plenty of time for her to have arrived at work. Matt lay in bed, and focused on thoughts of his mom, and jumped.

He had been to her office before, during the day, and had seen the walls covered with books, and rows upon rows of file cabinets, so he knew what to expect as his mind settled.

Except what he encountered was nothing like what he expected. His mom was kneeling on a bed, her naked body moving with rhythmic thrusts of the man kneeling behind her, her C cup breasts swaying with the motion. The sudden feeling of penetration caught Matt by surprise, but her body had obviously had gotten used to the sensation already, so Matt bit her lip to stifle the sound. There could be no doubt that his mom was having an affair!

Matt felt a hand in her hair, holding her head still, so she couldn't look around to see who was fucking her with such vigor. The cock inside her thrust again and again, almost pushing grunts out of her mouth. Then Matt felt an explosion of pleasure deep inside her body, her pussy clenching around the invading cock as she came. The man behind her kept thrusting through her orgasm, not slowing his rhythm until her orgasm had passed.

With a small, light slap on her ass, the man behind her growled, "Turn over - I want to see your face when I cum." He pulled out and turned her over, and Matt almost froze as the man's face came into view.

The man fucking his mother was her...
