Runs Off. Brian learns something is wrong.

Part of Ashley almost wanted to compliment him. It was a really attractive cock. But, no it was...weird...and creepy! She told herself. "Ugh...GOD...Brian...put it away! GO in your room or something....ughhhh!" She peeled her eyes away and **** herself to get out of the situation. She ran in the bathroom and locked the door. "Weirdo! I'm your sister!" she yelled from the bathroom.

Finally, Brian reached down and put his erected cock back in his boxers. He couldn't even button the fly back up as the head of his erection stretched out enough to make it tough. He simply ran back into his room and shut the door. "What the fuck....." he said outloud to nobody. But by the look he was giving his crotch, it was directed at his cock.

It was throbbing and the slight flexes seemed involuntary. He had to do something about it. It was one of those erections he knew wouldn't go down unless he relieved it. He walked over to his bed and kicked down his boxers. His cock did look really big! It had to be at least 8 inches and much thicker. He immediately grabbed it, and noticed his hand barely grasped around it. He then realized he could add a second hand. He had a full two hander! He was stroking himself with as much charisma as if it were his first time. His balls jiggled with his stroking movements and he could feel them jostle back and forth. After a few strokes suddenly, his sister came into his mind. As attractive as she was, he never looked at her differently. But images of their awkward encounter flooded his mind. He began to notice her loose fitting t-shirt with the big V-Neck that showed off her cleavage. Were her nipples poking into the shirt? Her tits are bigger than he thought. His cock flexed into his hands as subconsciously felt himself rocking his hips as he was fucking his own hands. The unnatural thoughts kept coming and each time it did, his cock bucked into his hands.

Her lips look really...full. She probably sucks a really good dick. The way they would wrap around it and suck on the head. Maybe she likes to lick and suck balls? She would look so good licking his big balls.....

He shook his head. "NO.." he said out loud. Why is she turning him on right now? Instantly, like a inner voice, the thoughts kept coming.

Because she looked at his dick. Didn't she? She looked for longer than she should have. Especially for someone who was disgusted and ran off. She licked her lips and then bit her lower lip, or at least his mind displayed the memory as such. He wondered how his cock would look inbetween her breasts. She must give an amazing titjob. Did she talk dirty? She probably did.

Brian was in a complete conflict between his brain and his cock. What he didn't know, was that something was different within him. Specifically, his penis. It was starting to influence the arousal centers in his brain. Right now, all he could think of was Ashley and all the dirty things she could do with him.

Within a couple minutes, his orgasm began to build and his entire body felt it. Every inch of his body was feeling amazing as it was all leading towards his cock. Her tits, her ass, her legs, her lips.........his hands and hips operated on auto-pilot as he moaned loudly and the cock flexed back towards him and began to erupt. Rope after rope of thick cum showered into the air, all over him and the bed. Brian was lost in the most intense orgasm of his life. His cock continued to pump over and over. After a lost track of time, everything finally stopped and subsided. Brian eventually regained some consciousness as he was soaked in his own sticky fluids. His cock softened and laying on his hip. It almost felt like an outer world experience. Brian knew he wasn't dreaming, but he also knew something wasn't right. It was like something was planting those sexy images of Ashley in his head...
