She's looking to see if we're out here," Emily said. "Do you think we should let her know we're watching?"
"Up to you," he said. "But, I don't mind it if you think that's what she wants."
"I feel so dirty."
"I feel like cumming two gallons," he said.
"Come on." Emily led him closer to the window. Not too close, because she wasn't sure if Charles was in on his wife's little game, but close enough so that the light began to fall on them.
Inside the room, Patty smiled and winked as she rocked back against her husband's forceful entry. Then, apparently to keep his attention off of the window, she said something to him that made him pull out and lay in the bed with his rock hard cock bouncing at an angle over his belly. Patty took the ropes off and knelt over his cock, sucking and pumping him for her neighbor's benefit. A moment later, she climbed up onto the bed to give him access to her pussy, and they continued in a 69 for awhile.
Emily responded to that sight by pushing her shorts and underwear down and sliding two fingers into herself. "Drop your pants," she hissed. "I've got to blow you."
Robert complied, asking, "But what about you?"
"I'll take care of both of us," she said. "Just turn a bit so I can still see the window."
By that time, Danny and Elaine had given up their limited view and sneaked over the back fence and along the hedge at the back of the Trent yard. They found a good vantage point at about the same time that their mother began blowing their father. It was hard to see their parents in the darkness of the yard, but the Trents were clearly visible, and the two grinning teens stood peeking over the hedge long enough to see their dad throw his head back at his release and Charles Trent unleash a torrent of goo on his wife's face. Then, fearing they might be caught, Danny and Elaine ran back to the house and up to Elaine's room, where they sat in darkness, grinning.
By leaving when they did the teens missed the most interesting part. After cumming on his wife, Charles left the bedroom and Patty skipped over to the window and opened it quickly. "Did you have fun?" she asked.
"Oh, yes," Emily answered, walking over to the window with Robert, holding his pants up, in tow. "How about you?"
"Great time. Good, I was hoping you'd bring hubby," she said. "Hi, Robert. Nice cock." She nodded toward his half erect member protruding above his pants.
Hi, uh, thanks."
"Gotta go," Patty said then. "Time for act two. Don't worry about Charles seeing you. He doesn't have his contacts in." She closed the window and returned to the bed just as her husband returned with his cock every bit as hard as it had begun.
"Damn," Robert said, looking down at his own cock. "That's a healthy hard-on he's got."
Emily touched his dick, and it began filling to full size again. "Don't worry," she said. "It's not a competition. So how's about a little fuck, big boy?"
Emily leaned against the edge of the Trent picnic table, her bottom seeming to glow with its own pale light in the light of the moon. Robert stood a moment, watching now as Charles swatted Patty's butt, the two of them laughing, Patty's breasts swaying with each playful blow. His cock grew even harder as he watched, and he dropped his pants and stepped fully out of them to approach his wife.
Robert swatted her butt, and a little yelp of pleasure popped out of her mouth. "Oh, tough guy, huh?" she said, arching her back a bit.
"You're a bad little girl, aren't you?" He swatted her again and then grasped both cheeks of his wife's bottom. "Are you going to open up and let me get at that bad girl little pussy?"
"Yes, sir," she said. "But what are you planning to do to me? Are you going to drill my wet cunt with that huge cock?"
"Oh, you are a dirty girl," he said then, swatting her bottom once more. "Yes, I'm going to slam my rod into your tight little pussy. I'm going to fuck your cunt till you can't stand the pleasure any more." He pushed her feet apart and bent his knees a bit, aiming his cock at her juicy opening. "Now, open wide"
Emily cried out as he jammed his cock home in one thrust. Then she gripped the table and pressed back against him, choking back her normal cries of joy as orgasm after orgasm washed over her.
The ever tightening pulse of her pussy, milked a might load from Robert's dick and he collapsed down on her back on the table.
"Holy shit, that was good," Emily sighed against the wood. "Very good."
"We're not done yet, young lady. Naughty girls don't get off that easy."
"They don't?"
"Oh, no. I think I've learned a few things tonight," he whispered hotly in her ear. "And, after I've got you tied up tight, you're going to have some fun with Big Wally."
Emily smiled. Yes, they were going to have some fun. The one thing she'd been worried about was Robert's reaction to this and how she was going to tell him. A week ago she'd been a sexually normal suburban mom. In five days she'd turned into some kind of bisexual voyeur. She wondered what her marriage was going to turn into now, but what ever happened she knew they'd be having a good time. A very good time, indeed.
