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.

"Oh Brandy! That feels so good!" Tim moaned as he turned to give her better access to please his cock. "Can I touch you?" he asked in a little boy voice hoping she would let him fondle her massive breast. So many times he had dreamed of sucking them and now it may come true.

Brandy had a painful look on her face and replied, "Oh baby, I really shouldn't even be doing this," she softly said, "Maybe later at the pool I'll let you give me a body massage!" She smiled pulling her hand from his stiffened cock. "Let's finish eating so we can get this day off and running!" she added giving him a sexy wink and started eating her breakfast.

"You ready for me to show you how to use my face cream?" Brandy asked as she walked into the bathroom wearing a small white string bikini, which barely covered her big breasts and went about half way up her rounded ass.

Tim couldn't help but stare at her as she leaned against him. "Fuck! You look great!" He gasped looking to her breasts as they tried to fall from the tiny covering and could feel his cocking coming to lie.

"I'm glad you like it! I wore it just for you." She smiled as she slowly turned around, giving Tim a look at all of her body. "I love the way it becomes see through when it gets wet." Brandy spread her legs, and added, "Even when I get excited, you can see all of my pussy." She teased Tim as she saw his eyes widen looking between her legs.

Tim looked at her face and replied, "You trying to kill me?" he asked as she moved to the sink and turned on the water. "I'm not sure what looks the best, your great tits or this wonderful ass!" he added as he pushed his stiff cock into her ass crack, enjoying the feel of her soft, warm flesh against him.

She lie back in his arms and replied, "Oh my, brother is all hard for his big sister," she giggled pushed her rounded ass into his hard cock, wondering what it would be like fucking her 18 year old brother. She could feel the heat forming between her legs and knew she was going to need help fixing it.

"Yes, I'm very hard for you!" Tim whispered in her ear as his hands moved under her fat breasts and he gently squeezed them. "Do I get to play with these later? I'll suck your pretty nipples," he whispered again as he moved his cock between her legs to her now wet pussy. "I'm hard and someone is nice and wet, is it all for me?"

Brandy closed her eyes and enjoyed the hard cock as it teased her delicate pussy lips. "Yes! It's all for you, my handsome brother," she moaned out, slowly spreading her legs to give the cock more freedom to explore her better. "You can do anything to them!" gasped when he began to roll her excited nipples in his fingers.

"So, I can massage them," he whispered in her ear as he softly kissed it, "and maybe I'll suck them, too!" he teased her as he gave them a tiny pinch, enjoying the feel of them.

Brandy was in his control and couldn't move. "Yes, you better suck them or I won't help you fix this!" she said as she turned to face him, squeezing his hard cock in her hand. "Let's get finished in here so we can get to the pool and have some fun." She started rubbing the cream on his face and felt his cock slowly moving between her legs. "Who's going to kill who? You have me more turned on than I've ever been in my life!" her pretty green eyes closed as his cock gently spread open her excited folds of flesh.

"You are so hot!" Tim moaned as his cock pushed against his sisters' excited pussy. "No wonder I hear you moaning so much at night. Something this hot needs a stiff cock in it day and night." Tim said pulling her against him, smashing her over-sized breasts into his chest. "Now all you have to do is, call me!" he added, moving his cock back and forth, teasing her pussy.

Brandy couldn't breath she was so excited, "Really? You'll fuck me whenever I need you?" she asked with love in her voice as she looked into his brown eyes. "You'd be willing to commit such a sin to please your big sister?" she asked as she moved her hips in time with his cock as it moved between her legs.

"Yes! I'd love to fuck anytime, anyplace!" he replied leaning to slide his tongue into her mouth. His hands moved to her rounded ass and he began to dry hump her pussy. "I want to cum on you so bad!" he moaned moving faster.

Brandy pulled from him, "No, let's save it for later. It will be better when we turn each other on as much as we can," she smiled and left the bathroom leaving Tim with a painful hard-on.

Tim casually walked towards Brandy as she lie on a recliner next to the pool. His hard cock led the way as he stepped over the chair and placed his cock on her mouth.

"You pervert!" she teased him taking his stiff cock in her right hand and proceeded to slap his bare ass with her left. "I'm your sister, what would people say if they saw this beautiful thing in my mouth?" she giggled leaning up to kiss the head of it. "Frankly, I wouldn't give a fuck!" Brandy moaned taking him deep in her wet mouth and began to suck him as hard as she could.

Tim looked on as his cock went down her throat. "Oh sis! You're wonderful!" he cried out hoping he wouldn't cum too soon. He tried pulling from the vacuum of her mouth but couldn't. "I don't want to cum in your mouth, I want to in your pussy!" he said as he finally pulled from her. "Let me fuck you, please!" he begged her hoping she would free him of being a virgin.

"No, I told you everything but that!" She replied trying to suck him more, but he pulled away. "Come on Tim, let me suck it," she pleaded with him. "I'll let you cum in my mouth!" she added giving her thin lips a long, slow lick.

He did everything he could to stay back; he had to hold out for the ultimate prize. "No, I want some of that hot pussy and I know you need a hard cock in it, fucking you crazy," he replied jumping into the cool water of the pool.

"Damn it, Tim I can't fuck you, I'm not on the pill," she moaned as she watched him swimming under the water hoping he'd settle for her mouth and maybe even her virgin ass. She always wanted Billy to take it, but he said, 'ass fucking was for fags.'

Tim swam to the top of the water and said, "Come on in so we can play!" A big smile filled his face hoping her horny body would take control and make her give in to him, if not he could always make her a new CD.

She returned his smile and knew it would be hell trying to refuse his advances. "You better not try to fuck me Tim." Brandy said as she walked to the pool, "I'm not on the pill or I would." Brandy added as she slipped into the water next to him. "I stopped taking them when I broke up with Billy."
