As Don finished packing his pack for his trip to summer camp, he heard noises coming from his parents' room. Past experience had taught him that when he heard noises at this time of the day coming from his parents' room, that that could mean only one thing. Quietly moving to his closet, Don silently opened the door and entered, moving to the back where a poster of Rachel Hunter hung on the wall. Carefully unhooking the bottom of the poster, it rolled up, revealing a hole about one inch in diameter in the back wall of the closet. Putting his eye to the hole, Don was able to see into the closet on the other side of his wall and through the open door of that closet into his parents' bedroom.
As he looked into the hole, Don could see his father, John, pulling his mother's, Doreen's, t-shirt off over her head, allowing her breasts to fall free. As he watched, his mother's nipples hardened and knurled into knots on the ends of her breasts, sticking up into the air. As his father leaned over and took them one by one into his mouth and sucked on them, he saw his mother fumbling with his father's pants, undoing the waist and pulling the zipper down. As his father sucked on his mother's nipples, Don saw her pull his father's cock out of his pants, squeezing it in her hand as she did so.
Don was always amazed when he saw his father's cock. It seemed so big to him. Even though he was only 18 years old and his own cock now frequently grew hard in his hand, the size of his father's cock still amazed him. He hoped that when he was older his would be as big as that.
As he continued to watch, his mother pushed his father backwards on the bed and pulled his pants off. Returning her attention to his cock, he watched as she fondled it, squeezing it in her hands and reaching down to hold and fondle his balls, rolling them in her hands. Then he saw his mother flick out her tongue and lick the end of his father's cock, tasting the drop of liquid that had formed at the slit of his cock. Then he saw her open her mouth and stick her tongue all the way out, licking the underside of his father's cock and then slowly sucking it into her mouth, closing her lips on it as she slurped on it, much like slurping on a popsicle.
As he watched, his mother continued to suck his father's cock into her mouth, constantly letting her tongue slide out of her mouth around the cock and lick it. After several minutes of watching her suck and lick his father's cock, Don saw her sit up, still holding his father's super hard cock in her hand. As she reached down to pull her shorts off, his father sat up and almost ripped them off of her. Don knew from past experience that his mother didn't wear any underwear, so when his father pulled her shorts off and he saw his mother's smooth ass and the thatch of blonde hair between her legs, it wasn't anything new to him.
As he watched his father push his mother over onto her back on the bed, spreading her legs as he did so, Don could see right into his mother's pussy, spread open and pointing right at him. At the sight of it he began rubbing himself through his pants, feeling his own cock growing as he did so. As he rubbed himself, Don watched as his father lowered his face between his mother's legs and stuck his tongue right into her pussy, causing his mother to arch her back.
Watching his father begin to lick and suck on his mother's pussy, Don let his own pants slide to the floor, and stepping out of them began to massage and fondle his cock, which had by now grown to its full size of 6". As he watched his father sucking and licking his mother's pussy, Don could see his mother squirming on the bed as he continued to stroke his own cock. So engrossed was Don in playing with himself as he watched his parents through the hole in the closet wall, he didn't hear his twin sister, Debi, as she came into his room.
Debi had finished her packing and was checking to see if Don was ready as she walked into his room, the door being slightly ajar. As she walked into the room, Debi called his name out. Once in the room, she couldn't see Don but she heard a sudden noise coming from the closet as Don frantically tried to pull his shorts up and cover the hole in the closet wall. When Debi heard the noise, she walked over to the closet and looked in, just in time to see Don fall down as he tripped trying to pull his shorts up. Debi gasped in surprise as she saw Don fall over on his back, his cock sticking straight up in the air, his face flushed with embarrassment.
"Don, what are you doing?" Debi asked, her eyes wide as she stared at his cock pulsing in the air.
"Nothing, nothing," he stammered, struggling to pull his pants up to hide his raging cock. "What are you doing here?"
"I finished packing and just wanted to see if you were through," Debi explained, fascinated as she watched him stuffing his still-hard cock into his pants as he finally succeeded in pulling them up. "What were you doing?" she asked.
"Nothing, it's nothing," Don stuttered, still embarrassed at having been caught by his twin sister.
As he tried to stand up, he glanced over to where the Rachel Hunter poster was still rolled up above the hole, where light was showing through into the closet. As Debi noticed his darting glance in that direction, she also glanced over to see what he seemed to concerned about and noticed the light coming through the hole.
"What's this?" she asked, moving towards the hole.
"That's nothing," Don answered frantically, trying to stop her before she could look into the hole. But he was too late as Debi bent over and looked into the hole. As he tried to pull her away, she gasped as she realized what she was seeing.
"That's mom and dad in their bedroom," she announced incredulously. "You're watching them," she accused.
"No, no, it's nothing," Don insisted, trying to pull her from the closet. But Debi wasn't having any of it. She pulled her arm from his grip and returned her eye to the hole.
"Wow, I can't believe this," Debi said. "I just can't believe this. They're doing -- they're doing -- doing
IT
," she exclaimed in shock. "This is amazing. Dad's pushing his thing into mom. I can't believe you've been watching them," she said, not moving an inch from her vantage point at the hole. "Wow, mom sure likes what dad's doing to her," Debi noticed.
Don just stood there in total shock. He had no idea what to do now. He couldn't believe his sister had caught him. He had been watching them for almost a year now, ever since he discovered the hole one day when he was changing posters on the wall. As he watched Debi watching through the hole, his cock stirred as he imagined what she was seeing.
Debi watched in delight as her parents fucked. She was fascinated by the sight of her father's cock sliding back and forth into her mother's pussy. She knew about these things, she had just never seen anything like this before. Turning from the hole, Debi looked at Don.
"What were you doing while you were watching them?" she asked. "Were you masturbating? I've heard that's what boys do," she said smugly as Don looked at her in horror.
"N-n-no," Don stammered, "of course not."
"Well, I saw you with your pants down and your thing all hard and sticking up in the air," Debi said. "What were you doing?"
"It was nothing," Don said, looking very uncomfortable, feeling his cock pushing out against his pants as it throbbed.
Just then they both heard a noise from their parents' room and they both started towards the hole. Debi, being closer, fixed her eye to the hole as Don caught himself.
"Wow," Debi exclaimed, "I can't believe she can do that."
"What?" Don asked, his curiosity starting to get the better of him.
"She's got it in her mouth and is swallowing the whole thing," Debi narrated.
"Oh, yeah, she likes to do that," Don said, then gulped as he realized what he had said.
