Carter awoke, drilling his hips down into his mattress. His painfully hard cock was making a tent in his shorts. His mind was fuzzy. He looked at the clock; it was 11:00 AM. He never slept so late since ages. But considering he was on his vacation, he had all right to take things easy and enjoy life.
It has been tough being posted at Baghdad for the last 14 months. When he got approval on his vacation last week, he was absolutely delighted. He had been looking forward to coming home for a long time.
Right now, he really needed some pussy to fuck and he needed that right then. His cock hurt. He started stroking his cock softly, looking to release. He remembered some of the hot girls he fucked while stroking his cock. He sat up suddenly, went to the bathroom.
On his way to the bathroom, he heard some muffled sounds from downstairs. He stopped jacking-off and followed the source of the sound. He passed through the hall, then his sister Carolyn's room. As he got closer to his mom's room, he was able to recognize the sound. It was his mom Cathy! She was grunting, loudly. He leaned to the door to get a good peek at the happening.
His eyes quickly scanned the room, he saw his neighbor Matt was standing beside the bed. His mom was in front of him, her ass high in the air, her body dropped down on top of the bed. "Come on Matt, fuck me harder," whispered mom. He could see Matt slamming back and forward into his mom. Matt's hips made smacking sounds against his mom's ass.
"Oh my god, what's going on in this house? Mom is fucking our neighbor when dad's gone on his business trip.... Wow!", he thought.
Mom's kept whispering words of encouragement "Yeah Mattie! Harder! Give it to me... harder"
Although Carter's eyes didn't want to believe what they were seeing, this made him hot like hell. He pulled his already hard cock and started jacking-off. He closed his eyes, and imagined his mom's ass high in front of him, open for his cock to fuck her harder.
He felt a hand on his cock and boobs pressed against his back. This was the day for him to freak out. He tried to put his cock in and see who it was. It was his younger sister Carolyn.
"What the heck ....You freaked me out .... Carolyn!"
Carolyn just laughed in the response.
Carter put his finger on her mouth, signaling her to keep it down. He didn't want his mom to hear them.
Carolyn and Carter had previous sexual exploration with each other. But they never had penetrative sex with each other. It had been limited to touching privates and some oral on each other – all this when Carter was in college.
Carolyn still holding Carter's cock smiled and signaled him to go to her room.
Both of them ensured that mom and Matt were still "busy".
Carter got a mind-blowing oral work from his sister. He fucked her good as her reward.
When they lay in the bed nude afterwards, Carolyn updated Carter about the recent family trends. Hearing about Dad and mom involving own daughter made him hot. The sight of moms heaving ass a few minutes earlier flashed in his mind. He sensed that he will soon be inside his mom's gaping holes. This was too much for him to handle. He was hard again. He got his sister on all fours and fucked her as if he was doing his mom. Carolyn enjoyed this extra-powered slamming. Soon both of them were rewarded with terrific orgasm.
Whole day passed by, he didn't speak much to Cathy. Cathy, being a mom, could smell there was something fishy, but didn't clarify.
Next morning, he awoke, smelling breakfast cooking downstairs. He loved a good breakfast, bacon, eggs, and hot cakes. He jumped up, threw on some old shorts and a t-shirt and headed off downstairs. For some reason, he went to Mom's room first. Looking at the state of sheet he knew that what he saw yesterday morning is daily routine. The 2 dents on the mattress sheet were indicative of the "crime" being committed in the doggy style.
He sighed and headed to Kitchen. He found mom alone there.
"Good morning baby," mom cheerfully greeted him.
"Get a good night sleep?" she asked.
"Had trouble getting to sleep, but once I settled down, I slept well," Carter responded.
"Did you now," mom stated, glancing at him.
"Did you hear Carolyn come in last night?"
"Nope, must have been after midnight," He responded.
He took his place at the kitchen table. He had not really looked at his mom as a sexual partner before, but yesterday's incident has changed the whole perspective around that relationship. His friends always said his mom was the greatest. A real cutie they said.
He looked at her now and wondered how she would look when she would be laying naked right in front of him. She was not perfectly toned, but was in good shape for her age. Her hair reached down below her shoulders. She had her bathrobe on, tied around the waist. After a fresh shower, nothing would give the impression that she had been fucked and eaten an hour ago.
He stood and moved to the sink beside the stove. He leaned back on the sink, watching her cook the breakfast. He noticed her face. For her age, her face looked years younger.
Cathy enjoyed his young son's extra attention on her body. After all, getting his son to her bed would complete the full family circle. Once Carter is added to their family fucking "club", she would invite her in-laws over again. The thought of full family orgy made her experienced cunt drip a little.
However, she didn't want Carter to know any of her thoughts at that point, as she wanted to enjoy these hot and tense moments.
"What," Cathy said as she glanced at him.
"Sorry mom," Carter said embarrassed about being caught staring at her.
