[MF] Tim’s Lust for His Sister Part 10 [Incest]

Tim stepped out of his room and headed over to his sister’s room. He felt very nervous and his heart was beating fast in his chest. What was Karen going to say to him? Was she mad at him because he said that he jerked off to her last night?

He walked very slowly to her door as if walking on death row. His hand shook as he softly knocked on her door.

“Come in,” his sister said.

Tim opened the door and stepped inside Karen’s room. She was stretched out on her bed with a book in her hand. It had been quite some time since Tim had been inside his sister’s room. There were posters of various rock bands and hip-hop artists all over the walls. He saw a big poster of Rihanna over her chest of drawers. There was a big mirror with various pictures taped to it.

“Hey,” Karen said with a smile. “Come in and close the door.”

Tim closed the door behind him and looked at his sister in fear. What was she going to say? She didn’t look upset. But what was on her mind?

“Come over here and sit down.” Karen patted her hand on the bed. Tim slowly walked over and sat down. His heart was beating even faster in his chest. He was so scared but also a little excited.

“So, we were having an interesting conversation before mom and dad came home,” Karen said as she looked at him. “I want to continue it.”

Tim stared at his sister and nodded his head. Karen looked at him with that same warm smile on her face.

“You said that you jerked off to me last night? Is that right?” She asked him.

“Yes,” Tim said in a shaky voice. “I hope you don’t think that I’m a creep or a sick pervert. I’m not.”

Karen shook her head. “I could never think that, Tim. I don’t think you are any of those things. I am not creeped out at all.”

Tim looked at his sister in surprise. “What? Really?”

“Yes, really. I completely understand why you would jerk off to me last night,” Karen said with that same warm smile. “We spent some time talking about sex and porn and what we liked to masturbate to. It is only right that you would think about me as you jerked off.”

Tim was shocked by his sister’s words. She was ok with him telling her that he had jerked off to her! She was not creeped out at all!

“Was last night the first time that you jerked off to me or have there been other times?” Karen asked him.

Tim felt his face blush bright red. He looked down at the bed as he couldn’t look his sister in her eyes because he was embarrassed. This was going to be much harder than he thought.

Karen chuckled softly. “It’s ok, Tim. You can tell me. Remember we can talk about anything.”

Tim looked back up at his sister. “I…I jerked off to you a few times before.”

“Really? What did you think about when you masturbated to me?” Karen asked him. She was very curious which excited Tim. He wanted to tell her everything.

“I thought about your…body…and what I wanted to do to it,” Tim said as he looked down at the bed. He wanted to look his sister in the eye as he told her how he jerked off to her but he felt shy all of a sudden.

“What kind of things do you want to do to my body?” Karen asked him.

Tim felt his face blush even harder but he lifted his eyes and looked at his sister. She appeared to be so relaxed and at ease with what he was saying. It helped him relax as well.

“I thought about…eating you out…and fucking you,” Tim said as he looked at his sister.

“Interesting. Was I doing things to you too in these fantasies?”

Tim nodded his head. “I would imagine you sucking my cock. I also thought about doing 69 with you.”

Karen looked at him surprised. “Oh! I have never done that before! Have you?”

Tim nodded. “Yes. I like it a lot.”

“I bet it does feel very good,” Karen said as she thought about it. “I know Nancy has done it several times. She said that she liked it when her boyfriend ate her out as she sucked his dick.”

Tim’s cock twitched from what his sister just said. Nancy was Karen’s close friend. She was very pretty and had big tits that Tim had jerked off to many times over the years.

“Do you cum in my mouth in these fantasies?” Karen asked him suddenly.

“Yes,” Tim said in excitement.

“Hmm. Do I cum in these fantasies?” Karen asked him with a smile.

Tim nodded his head. “Yes, I always make you cum when I eat you out.”

“Do you like to eat pussy?”

“Yes, I love it,” Tim said eagerly. He truly did love it and would eat pussy every day if he could.

“That is good to hear. I like having my pussy eaten,” Karen said. “Not too many guys enjoy it. I’m glad my little brother does.”

“It’s the best thing ever. I like to get a girl off when eating her out,” Tim said. “It is only right especially if she made me cum from a blowjob.”

Karen smiled at him. “I love to hear that, Tim. I can see you are getting hard as well.”

Tim looked down at his shorts and saw that there was a big ass pant tent. His cock was straining in his underwear. He could feel that he was already wet too from his precum. He blushed in embarrassment.

“I’m sorry,” Tim said. “I can’t help it.”

Karen gave him that same warm smile. “It’s ok. It’s perfectly fine. Don’t feel embarrassed. It’s only natural since we have been talking about sex.”

Tim smiled back at his sister. He was so much more relaxed and happy from having this talk with his sister. She was so open-minded and accepting of him.

“I’m going to ask you something and if you don’t want to do it, it is ok. Would you like to take your cock out for me? Can I see it?” Karen asked him with a smile.
