Tim Johnson walked down the hallway to his older sister's bedroom he dearly wanted to copy the new music CD that she had bought earlier in the day. He lightly tapped on the door and waited for a reply, but no reply. So he tapped it again and patiently waited, still no answer.
He reached to the door and gently turned it and couldn't believe his eyes. His sister Brandy, lay across her bed, her nightshirt pulled up exposing her fat 38-inch breasts and as he looked down he couldn't believe how wide her legs were spread. And the thing that really caught his eye was the 10-inch vibrator she was ramming in and out of her pussy.
Tim knew she masturbated, but had no idea that she ever did things like this. As he watched he could feel his cock filling with blood. He had never really looked at his sister in this way, but what the hell, she was lying spread-eagled on the bed fucking herself with a giant vibrator. He had never seen anything this cool in his life. Sure he watched his share of porno movies, but this was so much better.
"Oh God, I'M CUMING!" Brandy screamed out as her hips thrust up and into the air driving the vibrating toy so far inside her it disappeared. "Fuck me Billy! Fuck me hard baby!" she screamed again reaching to twist her tits huge excited nipples. Her hips continued moving in circles as the long vibrator remained deep inside her. She twisted her tender nipples so hard Tim wondered if she was trying to rip them off.
By this time, Tim had reached into his boxer shorts and began to stroke his long cock. He watched his sister's overweight body as she brought herself to what seemed to be a wonderful orgasm that was still going on. Her stomach looked so sexy and smooth when she lie on her back like this, most times it slightly hung over jeans. And her hips and thighs were so sexy spread out so wide.
"Oh Billy, I love your big cock in me!" Brandy moaned out to her imaginary lover as she reached to pull the vibrator from her soaked pussy hole. "I hate to stop, but I need to take a nice hot bath after that," she moaned easing her long toy from her body. She turned her head and that's when she saw Tim, watching her with wide eyes. She watched his hand down his shorts and couldn't believe how long his cock was. "You God Damn fucking jerk!" Brandy screamed as she jumped from her bed. "You fucking pervert! How dare you watch me do something so private!" she quickly walked to Tim and continued yelling as she looked down to his long, stiff cock. "Did you get your rocks off?" she screamed one last time as she shoved him so hard he fell into the hallway.
Tim lie on the floor in a daze looking up to his sister. "I knocked on your door, but you didn't answer. All I wanted was the new CD you bought today," he said looking up to see under her nightshirt and her dripping, wet pussy.
Brandy leaned down to his face as he sat on the floor, "Next time if I don't answer, do not come in my room!" she yelled out as her arm swung around and she slapped him hard across the face knocking his glasses halfway down the hall.
Tim sat on the floor rubbing his burning face and thought 'What a fucking bitch! I'll get even with you!' and he went off to his room to continue checking out some good porn sites he had found earlier in the day.
He clicked around a few sites until something very interesting caught his eye. 'Amazing new software that allows you to insert a subliminal message on any CD or DVD'. Tim had heard of the company before and knew they had a very good reputation so he decided to give the software a try.
The next morning Tim sat at the kitchen table eating a bowl of his favorite cereal when Brandy came into the room. "Hi pervert, got any plans on spying on me today?" Brandy asked in a very hateful voice as she reached into the refrigerator to get the milk. She quickly turned and hit Tim in the head with the large gallon jug knocking him to the floor again.
Tim wanted to kill her, but he also did not want to spend the rest of his life in some prison being butt fucked by some fagot the rest of his life. Brandy had always been very abusive and hateful towards Tim and he never knew why. "Your time will come, bitch!" Tim said as he pulled himself off the floor. His dear sweet sister would be his first experiment with the new software. When he ordered it he made sure to click next day delivery, so he knew it should arrive that day.
Brandy laughed at him as hard as she could and replied, "Sure thing, ass hole! I'm shaking in my panties!" and she wiggled her slightly overweight ass in his direction. Brandy never knew why she really hated her brother so much, maybe because he was so smart compared to her. Her only asset was her body and it was slowly deteriorating due to her excessive eating and her compulsive masturbating. It was nothing for her to masturbate 15 or 20 times a day and still be horny.
Later that day Brandy had went out with a friend when the UPS truck delivered Tim's new software. He ran to his room as fast as he could go to his computer. He inserted the disk and prayed it would help him take control over his abusive sister.
He carefully read the directions and followed every step. Now it was time to pick out something Brandy watched or listened to a lot. He thought to himself and decided to put his secret message on every music CD she owned and just to make sure he also put it on her hidden porno movies. It took hours to reburn all of the disks, but having control of the bitch that made his life a living hell made it worth it.
Tim carefully replaced each disk back into his sisters' room; she was a clean freak and would know if any thing had been disturbed. Now all he had to do was wait and hope it worked. He stayed in his room the rest of the day and the night not wanting to have another conflict with her.
Tim woke up late the next morning and made his way to the kitchen, finding his sister at the stove cooking something that smelled delicious. "Hi Tim!" Brandy said with a cheerful voice as she turned to smile at Tim. "I'm cooking some eggs and ham, would you like to join me?" Brandy smiled again and waited for his reply.
Tim smiled to himself and knew the software was working. "Sure thing, if you don't mind?" Tim replied as he looked to see her panty covered ass peaking out from under the tiny shirt that she wore. "Another thing, I'm sorry about walking in on you the other night. All I wanted was to borrow that new CD you bought." Tim added giving her rounded ass in another good look.
Brandy turned and saw him looking at her ass and she didn't care. For some strange reason she felt very affectionate towards him for the first time in her life. In fact, it made her very horny having him looking at her plump behind. Her boyfriend, Billy had dumped her for a skinny, tight ass cheerleader. It broke her heart and before she knew it, she was 30 pounds overweight and masturbated more times during the day than she could count.
She finished serving the food and sat next to Tim. "And I'm very sorry for hitting you like I did." Brandy said in a soft voice as she reached to caress the side of Tim's face. Brandy moved closer to her brother, so close he could feel her bare leg against his. "Did it turn you on seeing me doing that to myself?" Brandy softly said feeling wetness forming between her legs.
Tim couldn't believe what she had asked and then figured what the hell, "Yes it did, very much," he hesitantly replied waiting to feel her fist pounding the side of his head. But, it didn't happen; he looked over to Brandy and saw a big smile on her face.
"It did me too. I can't believe I got so turned on having you watch me like that." Brandy said reaching to run her fingers through his thick black hair. She felt sorry for him as she looked at his pimple-covered face. "After we're finished eating, I have some great stuff that will help clear up your face," she added seeing his eyes were focused on her bare legs, so she made sure to pull her shirt up just enough to expose her panty covered pussy.
Tim could feel his cock coming to life in his silk boxers and hoped she didn't see it. "That would be great! Maybe someday I'll have a chance to get laid!" he laughed out loud and leaned against Brandy's large right breast. He wasn't sure, but it felt like she pushed it against him.
"This is kinda fun being with you like this, maybe later we could lie out by the pool together. And if you be good, maybe later tonight, you can come and borrow another CD from me" Brandy said in a soft voice giving Tim a little wink. She would love to have him watch her again, maybe even let him sit next to her on the bed. It would be wild having him next to her while she fucked herself with the vibrator. She might even consider letting him use it on her.
Tim was in shock, "Do you mean what I think?" if he understood her right, she had just invited him to watch her masturbate with her vibrator. By this time his cock was at full hardness and his shorts had become a tent over his cock.
Brandy just smiled and softly replied, "I just invited you to come to my room and watch me fuck myself. Would you like that?" she asked leaning to caress his hard cock through his shorts. "Maybe I can even help you with this, would you like that?" she asked again as her hand began to move up and down his stiff cock shaft. "You're big, much bigger than Billy ever dreamt of. I'm glad Mom and Dad are going to be gone for three more weeks. It will give me and my sexy brother a chance to get acquainted." She whispered as her hand moved under his shorts.
