Tim’s sexual urges had been through the roof over the past few weeks. He had been jerking his cock off non-stop to incest porn. There was something about it that turned him on. The videos on Xvideos were great but he loved to read the various stories that he downloaded through torrents. These stories went even deeper and fed his fascinated mind with lots of detailed hookups between mother and son, father and daughter, and even sister and brother.
His hand would go to his cock as he read the stories in bed. Slowly, playing with himself as his eyes quickly took in the words on the screen. It didn’t take too long for him to get wet and for his precum to ooze out of his cockhead. His hand would pump his cock furiously as if it was his last opportunity to pleasure himself.
Many times, he would cum before he even finished the stories. His lust would take over and he would cum into a nearby tissue to catch his hot semen. He would moan and watch his cock twitch in his hand. Tim would not stop jerking his cock until he was completely drained. Every drop of his cum needed to be out of his balls.
Tim found that he could not stop reading these stories and noticed that he had a particular genre that he enjoyed the most. Sister and brother incest was what he really liked. He loved to read stories where the younger brother would corrupt his older sister into having sex.
It made Tim think about his own older sister Karen. He had always been attracted to her but knew that it was wrong to think like that. But, he couldn’t help himself. Karen was hot. She had long blonde hair that fell past her shoulders that Tim wanted to smell. She was petite and fit from always going to the gym. Tim would catch his eyes straying to her ass especially when she was dressed in tight workout pants. Karen had a great firm ass that made his cock twitch with lust.
She also had nice perky tits that weren’t too big or small. They were just right and Tim would stare at his sister’s hard nipples through her clothes whenever he got the chance.
The first time Tim jerked off to Karen was in a state of absolute horniness. He had been jerking off all day to his incest stories and was going to the bathroom when he walked by Karens room. Her door was slightly open and he saw that she was changing her clothes. Her bra was off and Tim stood frozen in place as he looked at his sister’s bare chest. Her pink nipples poked out from her small breasts. Tim’s cock instantly started to grow.
His eyes were locked on her breasts. He watched them jiggle as she put a shirt on. His cock was now hard as fuck and he quickly retreated to his room. He got into his bed and pulled down his pants. His hand flew to his cock and he began to jerk himself off rapidly. He closed his eyes and imagined Karen’s small perky breasts. Those pink nipples and those small mounds drove him crazy with lust. He came quickly and his hot semen came out in droves. It was a lot of cum and it flew all over Tim’s hand and legs.
He softly moaned his sister’s name while he played with himself. Afterwards, as he cleaned himself up, Tim felt a wave of shame and guilt hit him. He couldn’t believe that he had jerked off to his own sister! He had to be a sicko!
It proved to be difficult to look at Karen later that night as the family sat down to eat dinner. He could not meet her eye when she spoke to him because he thought that she would just know what he did. Karen noticed that he was not looking at him and made a comment about it. Tim said that he just wasn’t feeling good and was tired.
He went to bed that night with a mix of conflicted feelings. He thought about Karen and the image of her breasts came to mind. His cock grew hard but Tim tried to push it down with shame. Little did he know that his lust for his sister was not going to go away so easily.
