[MF] Tim’s Lust for His Sister Part 6 [Incest]

Tim spent the rest of the day feeling very excited and anticipated Karen’s return home. She had gone to the park and met up with her friends afterward. Tim had been disappointed because he had wanted to talk to her about what happened last night. He needed to know if she had masturbated and what she had masturbated to.

His cock had remained hard all day as he thought about his sister masturbating in her bed. He pictured her naked with her small perky tits and erect nipples in the moonlight. He imagined Karen rubbing her pink pussy with one finger. Her pussy was wet and ready for a cock to enter her. Tim thought about what Karen’s clit looked like and imagined her rubbing it fiercely as he moaned in the other room.

Their parents were home that day so Tim spent a majority of the day helping them with chores. He had a major hardon the entire time but was fortunate to wear jeans that were tight enough to keep his bulge from showing. It hurt to be so turned on but he couldn’t help himself. Karen kept popping up his mind as he cleaned the house.

Later in the day, while he was working on cleaning out his closet, he heard Karen enter through the front door. His heart jumped in his chest in excitement. He heard her greet his parents then she walked to her room. He quickly put his clothes back in the closet and closed it. He listened to Karen moving about in the next room.

He noticed that his cock was hard again in excitement. It was painful with the tight jeans on so he took it off. He heard a knock at the door and it opened just as he was stepping into his basketball shorts.

“Hey, are–Oh! I’m sorry,” Karen said as she saw that he was not fully dressed. Tim’s bulge in his underwear was on full display and there was no way that Karen had not seen it. An astronaut in space would have seen Tim’s obvious bulge!

“No, it’s ok!” Tim said quickly. His face had gone red in embarrassment but he was also excited to know that Karen had seen his bulge. “I was just changing. I helped mom and dad all day with cleaning so I was just changing.”

“Oh ok. I just wanted to see how you were doing,” Karen said as she stepped into his room and closed the door. She was still wearing her workout clothes from earlier and Tim’s eyes went to her legs momentarily before going back to her face. God, she was so hot! He thought as he looked at her.

“I’m doing good. Just trying to stay productive,” Tim said with a sheepish smile. Why was he so nervous? He could barely speak!

“Ok,” Karen said. Her eyes glanced down at his bulge that just would not go away. “Is everything ok? It seems like you’re aroused. Were you looking at porn?”

“No,” Tim said quickly. “I-I”

Karen laughed. “It’s ok. Don’t freak out, Tim. There’s nothing to be ashamed about. I would lock your door though with mom and dad basically in the next room.”

Tim forced a laugh. His heart was pounding in his chest and sweat had started to form on his forehead. He felt like he was going to have a heart attack if he didn’t calm down soon!

“What were you looking at?” Karen asked him curiously as she walked towards his desk. She sat down in his chair and opened his internet browser.

“I-I-I,” Tim stuttered.

Karen laughed again. “Come on, I want to see. You had to be looking at something really good to be so hard. What was it?”

Tim walked over to his desk on shaky legs. He prayed that he had cleared his browser history! If not, Karen was going to see all the incest porn that he had been watching.

“I-I was watching some videos with blondes,” Tim said quickly.

“Bring it up,” Karen said with a smile. “I want to see these blondes you like so much.”

“I-I-”

“Come on, just show me. How about this if you show me what you like to jerk off to, I will show you what I masturbate to,” Karen said.

Tim looked at Karen in surprise. She was looking back at him with a smile on her face. She was going to show him the porn she masturbated to! There was no way he was going to let this opportunity fall out of his hands. His cock twitched in his pants as he took the keyboard and then typed in Pornhub.

He saw immediately that he was still logged into Pornhub and that his recommended videos were all incest and stepcest videos! The recommendations were videos that he had been wanting to see but hadn’t gotten around to because he had many favorite videos that he watched all the time.

The titles of these recommendations were beyond wild such as “Stepsister begs for stepbrother’s thick cock,” “Fuck me like the whore I am, stepbrother!” and “Let your sister take care of you.”

“Oh, there’s a lot of incest and stepcest stuff here,” Karen said with a smile. “I don’t think I’ve seen any of these ones.

“You watch these types of videos?” Tim asked her in surprise. His heart was now slamming in his chest in excitement.

Karen laughed as she looked at his surprised face. “Yeah, of course. It’s like the most popular porn right now. Everything you see is about siblings or stepsiblings. A lot of it is hot, too.”

Tim was shocked by what he was hearing. His sister watched incest porn too! His cock twitched in response.

“Is that what you mainly jerk off to?” Karen asked him.

Tim nodded. “Yeah, it can be hot like you said.”

“Show me one of your favorite videos,” Karen said as she leaned in closer on the desk. Tim could see her cleavage and his cock twitched again.

He took the computer mouse and went to his favorites which had nothing but incest and stepcest videos saved. He clicked on a video that he constantly returned to. It was called, “My sis teases me before taking my cock.”

The video featured a blonde petite pornstar and a tall man. The sister walks in on her brother in the shower and she begins to tease him as he tries to get dressed. This leads to them fucking in the brother’s bedroom.

Tim looked at Karen as she watched the video with a slight smile on her face. She seemed to be totally engaged with the video. His cock was getting even harder from both the video and his sister.

“This is hot,” Karen said. “I like it. I’ll have to check it out tonight.”

Tonight?! Tim thought. She was going to masturbate to his favorite video tonight?!

“Did you masturbate to this last night?” Karen asked him curiously. She looked at him with a small smile on her face.

Tim knew he had to lie. He couldn’t say that he had jerked off to her! He quickly nodded.

“It’s so fucking hot. I like the way he fucks her against that wall,” Karen said.

“Did you masturbate last night?” Tim asked her quietly.

“Yeah, I did. Let me show you what I masturbated to,” Karen said. She typed in threesome in the search bar and then she scrolled down the page until she got to a video of two girls and a man fucking on a balcony.

“This is one of my favorite videos,” Karen said as she looked at Tim. He watched as the three of the pornstars fucked intensely on the balcony of a house. Tim was getting turned on by it. It was a hot video!

“What do you think of this video?” She asked him.

“It’s sexy. Those girls are hot, especially the blonde one,” Tim said as he watched the video. He was now stiff as a board.

“How about I watch your favorite video tonight and you watch mine?” Karen asked him.

Tim nodded quickly. “Yes, that would be cool.”

“Great. Thanks for showing me your video. Hopefully, my favorite video will help take care of that later,” Karen said as she pointed at his hard cock.

Tim looked down at himself and tried to cover his bulge with his hands in embarrassment. Karen laughed.

“It’s ok, Tim. I’m wet myself,” Karen said with a wink before she left his room and closed the door.

Tim stood there with his raging boner and thought about what they were going to do tonight. He was going to watch the video that was for sure but he was going to cum to Karen.
