Shock, Horror, and Arousal?

Josh looks around to where his mother could be, looking in several of the open rooms. The people inside seemed to be more into each other than what was going on around them, and he was certain he heard the sounds of sex from some of them. He was really thinking this was NOT your average bbq.

As he made his way down the hall, he heard a familiar voice coming from a room with a door cracked open.

"Henry! We can't!" Despite the protests, the woman's voice was clearly happy.

"Yes we can, Claire," comes a teasing male voice. The sounds of kissing can now be heard.

"No, no way that's-" Josh quietly sneaks by the door, and peeks inside. He was shocked to see his mother making out with a guy who was clearly not his dad! The man appeared to be Asian, and around his mom's age. They stopped kissing, the man moving to kiss his mother's neck. To his horror is mother was smiling, her hands in the man's hair.

"We shouldn't, Henry," Claire Winters protested, but she was moving his head to her breasts. "What about your wife?"

"Henry", as that seemed to be the guy's name, kissed her breasts through her dress. His hands went to slide the top of her dress from her shoulders. Josh was frozen in place as his mother actually helped push the top of her dress down, exposing her breasts.

"What about your husband?" He asks in turn, smiling and taking one of Claire's nipples into his mouth.

What Claire said next horrified Josh.

"Fuck him," she said with lusty determination. "No, better idea: Fuck me."

Josh wants to yell, to barge in, but he keeps standing there, quietly watching. His breath hitches when his mother turns to the dresser, and hikes her dress up, giving him a unhindered view of her full ass. Henry undid his pants, letting them drop to the ground. He quickly came up behind Claire and rammed his cock insider her.

"Yes! That's what I needed!" Josh barely recognizes the tone of voice his mother was using. It was husky, deep, and..alluring. Claire was looking herself in the mirror. "Make me cum, Henry. I want to watch myself get off."

Henry chuckles, thrusting hard into her. Josh watches mesmerizes as he watched his hot mother's breasts bounce, and the way her ass moves when Henry pushes into it. He always knew his mother was very attractive, but this was something else.

Josh's thoughts are interrupted when Henry asks a question.
