Jeanie Wilson unlocked the front door and walked in. Her mom's car wasn't in the driveway, so she knew her mother wasn't home. She shrugged. She was about four hours early anyway. She set her suitcase in the kitchen and hung her coat in the hall closet. That was when she heard the faint noises drifting down from upstairs.
Jeanie listened for a moment. It sounded like someone was having sex! She had sat many Saturday nights with her ear pressed to the wall adjacent to her parent's room until she started spending her weekends in search of her own. She knew when people were having sex. If her mom wasn't home, and her dad was gone until the weekend, who could it be?
"Ohh..." she thought, "Could it be Marty?" Then "No way, it sounds like a grown man!" Jeanie's curious nature made it impossible for her to ignore the situation. She just had to investigate.
Jeanie crept up the stairs. It was coming from Marty's room! She paused in front of his closed door, wanting to find out what in the world was going on, when she realized two things. She could tell it was coming from the television in his room, and she recognized her mother as one of the participants! Shocked, Jeanie opened the door slowly.
Marty heard a small "oh!" behind him. He froze for a moment, then slowly turned, his hand still around his cock. He looked up at his sister standing in the doorway and back to the television set. He quickly leaped up and turned the set off, knowing it was far too late for that. He grabbed the towel on the end of his bed and covered himself with it as she walked in, knowing it was a little late for that too.
"Well, well... what have you been up to, Marty?" Jeanie taunted him as she walked over to the vcr. She pushed rewind and turned around. "Don't be embarrassed, Marty. Everyone does it, even me."
She turned back to the television and hit the "on" switch, then restarted the tape. "Let's see what my brother's been doing."
The few seconds of lead passed, and the view of Selena on her knees giving a strange man a blow job came on. Jeanie's mouth dropped open, then she slowly closed it. She sat and watched the whole thing without a word, so stunned she didn't even realize when her hand went between her legs. She turned to Marty when the tape was over.
"How did you manage this?" she asked. Then she giggled, looking at the towel tent in his lap. "And how ever are you going to manage that?"
"Well if you hadn't come in, I would have managed just fine, thanks." Marty returned. "Now I guess I'll get over it."
He glanced pointedly at her own hand in her lap. "Looks like you got something to manage yourself."
"I told you everybody does it," Jeanie replied. "I do it all the time. Well, whenever I'm horny and I don't have my boyfriend around, that is. And once I even did it in front of him."
"Wow." Marty was impressed. And his stiffness wasn't subsiding at all. If anything it was even more demanding. There was something too wild about listening to his sister tell him she masturbated in front of her boyfriend right after they watched their mother being fucked on tape.
"I wish I could see that up close," Marty said. His hand brushed across his towel-covered cock almost absently before he settled it on his knee. "I've never even seen a pussy up close."
"You're still a virgin? Oh, Marty!" Jeanie gaped at him. Then she asked, curious, "So how did you come by this tape?"
"I filmed it myself." he answered. "I stood in the doorway and watched through the camera while she let two guys fuck her. It was awesome."
"Wow," said Jeanie as she reached over and rewound the tape. "I can't believe you did that!" She hit the play button again and sat there watching and listening to the two men fuck her mother senseless.
"Damn, that is so hot!" she exclaimed when the tape finished. "I can't believe Mom is such a slut! Has she ever done this before?"
"I came home one day," Marty began, "and there was some guy fucking her in the garage. I watched it all as he slapped her hard on the ass and fucked her right off the floor. I heard her talking to Glenda after that and telling her how much she liked it. Then I heard Mom talk to her about setting her up to fuck somebody else, so I was ready. I didn't know it would be two guys!"
"Watching that tape has made me so horny!" Jeanie looked sideways at Marty. "Do you really want to see what a girl looks like when she's masturbating?"
