Nate took the stairs two at a time as he hurried toward his bedroom. The sick feeling he got in his stomach when Claire was telling him about the girl from the site was a thousand times worse. He stopped at the top of the stairs and stared at her door for several long seconds. He thought about busting in and telling her everything but he just could not bring himself to do it. To admit to her that he knew she had made a profile on the website would be to admit that he looked through all of her pictures. She would think he was a disgusting pervert and hate him. Even worse, there was a good possibility that she would tell their parents about what he was up to. The fact that he was perving her profile would trump the fact that she had posted the pictures or made the posts.

He sighed heavily and started to his room. As he got closer he could hear her giggling. He prayed that she was just chatting with one of her girlfriends on IM. He paused and considered knocking on her door and making up some stupid reason for his interruption but he couldn’t bring himself to do it. He knew there was a good chance that he would break down and tell her everything.  Instead, he walked to his room. His computer was still on and logged into the site. He clicked on her profile and then the link to her most recent posts.

His fist slammed against the desk as he saw the comments the others had left for her. The worst was the link to the preferred messenger that allowed larger groups to view webcams. She had promised to put on quite a show for all who wished to watch at 11. Nate glanced over at the clock and noticed that it was in less than 40 minutes. He had to give it one last try. He opened the private message box and began to type a quick message. Instead of sending it to his sister, he sent it to Claire.

“Do me a favor. Warn this chick calling herself PunishmePlease about JR. I’ll owe you big time.”

He waited impatiently for a reply and after a few minutes he got one. She had agreed to do it but doubted it would do little good. Most of the girls there just ignored the warnings. Her next message only said “Told her. She says she will steer clear of him. Remember; bring the cherry scented lube next time.” Relief and satisfaction surged through him as he sat back and stared at the screen. For the moment, he felt a little better.

He decided to retreat to the shower to wash away the scent of sex and cannabis smoke. The room quickly filled with steam as he adjusted the knobs until the water was just right. He left his clothing lying on the bathroom floor where they landed when he removed them. He stepped inside the shower and closed his eyes while the hot water beat down on his skin. For those first few minutes he managed to push all thought from his mind. The bliss however did not last long. Soon they started to creep back in. He knew at any moment Kayla would be starting her broadcast. Dozens of people would be logging in to watch whatever she was willing to do for them on cam. There was a part of him that demanded he just get out of there. If he left the house he could postpone dealing with the inevitable. If he was not there he was sure he could calm himself even if only for a short time.

He again thought of her photos. His cock immediately began to twitch. Her willingness to perform for them meant he could see much more of her. He could watch her face contort in the sweet mixture of both pleasure and pain. He turned the water off and opened the shower door. Nate wrapped the thick ivory bath towel around his waist and stepped out. He walked to the sink and opened the medicine cabinet, careful not to let his own image catch his eye. After he used the stick of deodorant he returned it to its spot. This time he was not so lucky.

His palm touched the mirror and wiped a wide swipe through the fog that coated it. He glared unhappily at the man who stared back at him. He barely recognized himself anymore. It was true that he was no angel. He had done plenty of bad things in his life, but this was unspeakable. Normal people did not long to fuck their blood relatives. They did not lust after them as he lusted after his sister. He told himself it was more than just lust though. He didn’t want to feel the way he did about her but it seemed there was nothing he could do to change it. It made no sense how something the world viewed as so wrong could feel so incredibly right to him. Several minutes passed before he could move. He gathered his clothes off the floor. The door swung open and he stepped out into the hall. It was hard for him but he managed to make it back into his room without so much as glancing at her door. It was a small victory but one he would happily accept. He slipped on a pair of baggy blue boxers and tossed his clothes in the hamper.

It was a struggle to keep his mind occupied but he knew he had to try. If he didn’t, he would end up giving in to the dark need to see his sister’s broadcast. The video games he often played held no interest for him today and neither did chatting with his other friends online. His thoughts just kept turning back to his sister. The thought of those creeps getting off while watching her infuriated him but there was nothing he could really do. He knew nothing short of busting in there and taking away her laptop would stop the show. For a second he entertained the thought of saying one of his friends alerted him to what she was doing and demanding she stop before he tells their parents but he knew that the thinly veiled lie would fall apart quickly. He resigned himself to the fact that the show would go on as planned.

He sighed heavily as he sat down in front of his computer. Just thinking about what he was going to do had his dick growing hard. He looked down at the way it tented out his boxers. There was no denying that he wanted her. Kayla was quite a beautiful young woman. Most of the guys in her life had pictured her naked and daydreamed about doing the same things he had fantasized about. The only difference was she wasn’t their little sister. She was his. He knew he was sick but he didn’t care. As long as no one knew the truth, he would be ok.

He clicked on the link and was immediately redirected to the room where she had set up her video chat. There were already dozens of guys and a few of the females lurking in the shadows as they waited for her to begin. The laptop was positioned at the foot of her bed so that she would have plenty of room to stretch out once things got underway. There sat his not so innocent sister wearing a little purple tank top and black panties. The way she smiled made it clear to him that despite what the others may have thought she was not that happy. Line after line flew by in chat as the viewers greeted her and begged for her to undress. He sat there and watched in silence as she responded with a few courteous hellos. It pained him to watch her do this but he knew this was what she thought she wanted.

It wasn’t long before she reached down and gripped the bottom of her shirt and slowly peeled it up over her head. She tossed it aside and let them see her perfect perky breasts. Nate no longer watched his sister’s face. Instead, he stared at the twin mounds of creamy white flesh and longed to feel them against his palms. Kayla’s swollen nipples were noticeable through the thin cotton fabric but now they demanded even more attention. She caught one between her thumb and forefinger and gave it a soft squeeze.

In that moment his eyes went back to her face. He had to see her reaction to it. The slight change in expression spoke volumes about her level of arousal. He watched as she did it again, this time pinching both simultaneously. He envied her for being able to do so. He had tried to refrain from touching himself but she was making it hard to keep from it. She had been sure to leave the sound on so that they could hear the sounds she made. They encouraged her to keep pinching and tugging on her nipples which she did. The faint almost inaudible moans were soon replaced with louder ones.

He could see it in her eyes. She wanted more. The words flew up the chat screen so fast that he was amazed she had time to read any of it. Several of the men telling her to show them what a slut she was.  It made him want to throttle them but he desired the same thing they did. He was desperate to see more. It did not take her long to give them all what they wanted. Her legs were parted just enough that he could see a glimpse of her panties between them. There, he noticed what many seemed to overlook, a small patch of fabric that was slightly discolored from her wetness.

Nate couldn’t hold back any longer. His cock was aching for attention already despite the fact that he had just gotten laid such a short time ago. It was a hard fought battle but the need was too strong.  He stood up just long enough to slide his boxers off and let them fall to the floor at his feet. His thick cock jutted out obscenely as his eyes returned to the screen just in time to see his sister’s right hand drift down over her flat stomach toward her panties.

At first she just slid them over the fabric as she began to rub her clit. Her eyes fluttered as she began to tease the tiny pink nub. The wet spot on the gusset of her panties was becoming larger as it pressed harder against her lips. Line after line of words pushed the previous ones off the screen as they urged her to remove the panties. She gave a slight smirk and shook her head no. Instead, she slipped her fingers under the waistband and began to touch her bare flesh. Her moans grew louder as she manipulated her clit.

Meanwhile Nate’s fingers had wrapped around his cock. He was determined to take it slowly so that he would not cum until she did for the last time. He could almost hear the sound of her voice without his speakers being on. He would have given anything to go in there and push her hand away so that he could peel those troublesome panties off and taste the sweet essence that flowed readily from between her lips.

Kayla’s body shivered as she grew closer to her first climax. Her fingers were moving faster beneath the panties that obscured the view of her perfect little slit. The moans grew louder as well and twice as frequent. It was torture to watch the beautiful girl in the throes of pleasure and not be able to assist her but no one looked away. More and more people joined the room to watch her but Nate barely noticed anything but her. Her chest was heaving as she grew closer and closer to orgasm. The viewers begged her to take off the panties so they could see every last second of it but it was no use. She was so close that she could not make herself stop.

The sound carried through to his room as she let out the loudest moan yet. Her body shuddered as more of the fabric of her panties darkened as more of her juices spilled out. Nate longed to be there lapping up every last drop as he held her in place. She would not have been given the time to recover. He wanted to leave spent and satisfied. He hated himself for how badly he wanted to touch his own sister but the feeling was as powerful as his need to protect her. He continued to stroke his rigid cock as he watched her laying there panting.

When she finally pulled her fingers from her panties a wicked grin formed on her lips. She licked each one clean before she moved both hands down to her hips. She pushed the panties down slowly as she brought her legs together. The panties sailed across the room as she tossed them toward her clothes hamper. Before she settled back into position she leaned over and grasped small handle on the nightstand drawer to pull it open. Her hand reached quickly inside the drawer and emerged with a purple vibrator. Nate’s eyes widened as he saw the size of it. It appeared to be close to the same size as his girthy cock. He let out a soft groan as pre cum trickled from the tip of his engorged shaft. He began to stroke his cock a little faster as he watched her rubbing the tip of her toy up and down her slick lips.

She pressed the tiny silver button on the base and it hummed to life. Her body stiffened slightly as the vibrations began. She was so turned on by the fact that they were watching. Kayla’s fingers guided the toy inside her slowly, taking just an inch of two at first. Her left hand returned to her breast as she began to knead the fleshy mound. Her voice rose again as she fed more of the toy into her needy little pussy. It was almost too much for Nate to bear. He knew that he would cum soon if he continued to stroke his cock. It would be a battle of willpower until the end.

Her body began to writhe as she blocked out the words on the screen or the thoughts of anyone staring at her body. Her mind was focused only on the pleasure that her body was receiving from the vibrating lilac toy. Her hips started to rock as she worked it in deeper and a little faster. Her juices clung to its matte finish causing it to glisten. Her moans were so loud that he could hear each one of them. They were becoming more frequent with each passing moment making it very obvious that she was about to climax. He was so focused on the thought that she was performing just for him he swore he thought he heard her moan his name. It was enough to make him lose control.

His grip tightened ever so slightly as his fingers worked up and down his shaft to the same pace that she worked the toy in out of her tight little wet hole. He imagined how good it would feel to be burying his cock deep inside her. Just as he felt that familiar tingle in his balls he watched her shudder and cry out once again. The sight of his sister in orgasmic bliss made him explode. Thick ropy spurts of seed splattered against his shirt as his eyes remained glued to his sister as she bucked and moaned. One way or another, he would feel her writhing like that as her pussy clenched around his cock in the throes of passion. Of that he was certain.
